/in /by

Remember the good old days, when airplanes were built from wood and linen, nailed and glued together? Not many people do, actually. Planes quickly became metal machines, requiring new methods to keep all parts firmly together.

With faster engines came stricter building requirements and safety standards. Commercial flights soon took off: the ability to take more passengers helped reduce ticket fees and travel times. Aircrafts with bigger cargo holds meant we could transport more freight per trip. But whatever we did, weight remained a factor that determined the limits.

What a shame that, to this day, much of that weight is contributed by parts that have no other function that to keep it all together: fasteners. No wonder that metal adhesives became a vital part of the aviation industry.

Metal adhesives for the aviation industry

Planes have become behemoths of the sky, and weight reduction is more important than ever. No matter how big the aircraft is, there is always a limit to the total weight allowance of the plane. Often a third of the total weight of a plane is made up by the fuel alone. Taking the maximum takeoff weight into consideration, the average commercial plane can only transport some 20,000 kg of cargo, including passengers and crew. Of course, the payload hugely depends on the type of aircraft and the circumstances, but weight limits remain a deciding factor when it comes to transporting goods through the air.

Large commercial aircrafts are built with millions of parts. A considerable number of those are fasteners. According to many sources, the Boeing 747 is held together with 3 million fasteners! Not all aircrafts may need that many of them, it is clear that hundreds of thousands of fasteners take a considerable toll on the payload.

Of course, certain parts need to be detachable for servicing and replacement. But replace fasteners with a reliable metal-to-metal adhesive, where possible, and a lot of weight can be saved.

Choosing the right adhesive can be a daunting task. With technology constantly raising the bar of what the aviation industry is capable of, it is vital that you are constantly aware of new materials and methods. This is not a quest you should take lightly. Expert help could save you a lot of time, and headaches.

Metal adhesives, requirements and uses

Metal adhesives for aviation purposes must have one paramount property: reliability. The stakes are high and the industry demands an adhesive that performs well under every imaginable circumstance. It must maintain a reliable bond at very high temperatures, but also in the freezing cold. The bond must remain completely stable under extreme stress, withstand numerous hours of low and high frequency vibrations without a problem, and be highly resistant against a fair number of chemical substances.

There are a lot of uses for metal adhesives in the aviation and automotive industry. Think of small magnetic engine parts that must remain in place, no matter what. There is a use for cyanoacrylates in numerous places, for instance to keep parts in place while the actual bond with a slow curing glue or sealant is made. Another common usage is the range of liquid thread lockers, preventing nuts and screws from loosening due to vibration.

Body panel adhesives for vehicles

With the adhesive technology in North-America progressing, adhesive solutions for body panels are created which allow for quicker vehicle repairs and assemblies. These adhesives especially reduce repairing and assembly time where no welded bonds are needed or they are not possible. Furthermore, these body panel adhesives can also be used as a replacement for mechanical fasteners.

These are not the only benefits that body panel adhesives provide. Even though the industry for them has strict requirements, they can be customized for specific vehicles. This means that the bond quality will not falter while possibly speeding up the assembly process of these vehicles. These adhesives are used in transport and vehicles sectors such as road transport, public transportation as well as agricultural machines. The use of these adhesives in vehicle repair and production has been increasing on a global scale, even outside of the United States and Canada. A shift from mechanical fasteners to body panel adhesives can therefore be seen. To understand the reason for such a shift, the advantages that body panel adhesives bring in comparison to mechanical fasteners will be listed underneath.

Advantages of body panel adhesives

  • Lighter: mechanical fasteners are heavier than most body panel adhesives and a switch can lead to up to 80 kilograms of weight reduction. This would mean that the use of adhesives can lead to noticeable reduce of fuel consumption.
  • More efficient: as mentioned before adhesives can reduce assembly lines. The application process for body panel adhesives can be completely automated. Furthermore, the materials for welded bonds and fasteners are more expensive than those of adhesives making adhesives a more desirable option.
  • Anti-corrosion: adhesives are not corrosive unlike mechanical fasteners which will begin to rust during the lifespan of a vehicle. Sometimes adhesives can even prevent corrosion from spreading by functioning as an anti-corrosion barrier between the metal panels, contributing to the overall durability of the vehicle.
  • Noise cancellation: due to the flexibility of adhesives, they can effectively be used to cancel vibrations and noise to be felt and heard within vehicles. This will improve passengers’ comfort which is most favorable for buses, trains or other public transport.
  • Fastening diverse material: body panel adhesives can be used to bond materials of diverse nature. It has the ability to bond metals to composite materials. Since the use of composite materials in the vehicle industry has been increasing many other vehicles might benefit from using body panel adhesive systems.


Advantages of adhesives for repairs

Also in vehicle repairs, body panel adhesive systems have proven to be beneficial. The following benefits come along with body adhesives in vehicle repair applications:

  • Quicker repairs: body panel adhesive can be applied quicker than mechanical fasteners and does not have to rely on specialists to apply them which are needed when it comes to welding fasteners. Therefore, repairs will be executed sooner having transport vehicles ready for service in less time.
  • Allow harder repairs: Tough to reach spots that cannot be welded can be reached by adhesives depending on the manner of application. This opens up possibilities for specific vehicle reparations.
  • Repairing diverse material: Welding is also not an option when the materials are of a variety. As mentioned before the vehicle industry is starting to depend more on composite materials which also need to be repaired. Therefore, it might be easier to depend more on panel adhesives which are not dependent on the nature of the material.

Adhesive applications in assembly lines

car door with body panel adhesives for water stripping
Body panel adhesives are often applied as assembly line adhesives to car doors as weatherstrip and watershield bonding.

Body panel adhesives in vehicle assembly are suitable for the application of roof skins, body skins and quarter panels. We will discuss the most frequent applications which are weatherstrip bonding and watershield bonding.

Weatherstrip bonding, also known as waterstripping, is a way of protecting the vehicle interior from its environment. Body panel adhesives can cancel vehicle vibrations because of their flexible nature even after curing. Most importantly they retain their qualities even in harsh temperatures or weather.

Watershield bonding is when the film is bonded directly to a vehicle’s door to protect the electrical parts from water damage. The adhesive systems for watershield bonding can be systems that are pre-applied or directly applied.

Applications of body panel adhesives

The application processes that were mentioned before can be performed using various adhesive technologies. More or less they can be divided into three: waterborne, solvent based and hot melt adhesives. The most suitable adhesive is eventually decided upon the characteristics of the product and its assembly line. We will mention some of the characteristics of each of the different solutions:

Waterborne are liquid adhesives which do not contain any toxic solvents, making them safe and easy to use. On the other hand, hot melt adhesives are completely solid and environmentally friendly. They are applied by using heat and contain no solvents which results in minimum waste. Lastly, solvent based adhesives are liquid that can be considered stronger than other liquid alternatives. However, they have VOC values that are higher and therefore require safety measures.

Materials that can be found in the body panel adhesives in cars include MMA, rubber silicone, MS polymers and polyurethane. Butyl-based or hot pressure sensitive adhesives (HMPSA) are generally used when it comes to hot melt adhesives.

Finding the body panel adhesive you need

Even now that you know body panel adhesives bring many benefits along it is still tough to find the right one to assemble or repair your vehicles. If you are interested in more information on advantages and solutions for your garage do not hesitate to contact us. We will gladly help you find the adhesive system that fits your product and answer any questions that might have popped up while reading this article.

Adhesives for attaching antennas to buses, trains and trucks

Through technological changes there has been a shift in demand from mechanical fasteners to that of adhesives for attaching antennas to vehicles. These vehicles include but are not limited to buses, trains and trucks. In this article the benefits of these adhesives will be discussed in order to explain why this shift in demand has taken place. It is also important to note that this shift which can be spotted in the United States and Canada is not limited to the North-American continent: it can be seen on a global scale.

Benefits of adhesives for attaching antennas

The use of adhesives as opposed to mechanical fasteners brings many benefits with it, also when applied in order to attach antennas.

electric locomotive with receivers attached with adhesives for antennas
Adhesives for attaching antennas contribute to vehicle weight reduction, allow for aerodynamic design and offer increased durability.
  • Higher durability: mechanical fasteners are prone to create corrosion of vehicles, whereas adhesives prevent corrosion and thereby lead to an increased durability. Additionally, when adhesives are used to fasten antennas, the stress is equally distributed, unlike with mechanical fasteners.
  • Flexible design: adhesives permit more flexibility in their designs, making it easier to reach a more aerodynamic design.
  • Improved production: the production and application of adhesives is a fast process, which can reduce the production time of vehicles that incorporate them. A reduced production time will benefit the production costs leading to a cheaper process. The use of adhesives for antennas also enables fast repairs and replacement.
  • Weight reduction: mechanical fasteners can create up to an 80 kilogram difference in the overall weight of a bus compared to the use of adhesives. Reduced use of fasteners in attaching antennas contributes to the overall weight reduction.

Characteristics of rooftop antennas and adhesives

As antennas are most often placed in plain sight on the rooftops of vehicles, adhesives need to share the same characteristics as these antennas. The most important features these adhesives and antennas possess are:

  • Easy to (re)place: during a vehicle’s lifetime it is highly likely their antennas have to be replaced multiple times. Therefore, antennas and adhesives are to be easily applicable as well as replaceable without the process being too time consuming.
  • UV-resistant: as mentioned before antennas are mostly placed out in the open on the roof of vehicles, which means that they need to withstand the UV-rays of the sun. Adhesives for antennas are therefore also UV-resistant.
  • Conductive: most antennas require to be placed on a surface that is conductive, which means that the antennas themselves as well as adhesives are also made to be conductive. If they are not it can disrupt the magnetic field which antennas require to function properly.
  • Tough: An adhesive has to be tough to keep the antenna firmly in place even when dire weather conditions and high speeds are involved.

Choosing the right adhesive to buy for your vehicle

It is crucial to know which adhesive would be the right fit for your antenna and your vehicle as each of them has their own requirements. Finding an adhesive then, that fits both the antenna’s as the vehicle’s requirements, can prove to be a difficult task.

Increased use of adhesives and sealants in bus assembly processes

There is a trend in the vehicle industry of replacing mechanical fasteners with adhesives and sealants. Buses are acknowledged as one of the vehicles that this trend can be traced back to. Trends can be seen in the bus industry in Mexico, Canada, the United States and many other countries. This article will look closely into the adoption of adhesives and sealants in bus assembly specifically. This is to give more of an in-depth analysis of the possibilities and solutions which adhesives and sealants can offer in the bus industry.

Adopting adhesives and sealants in the bus industry

With the increasing growth rate of the use of adhesives in the bus and other industries it is necessary to discuss the many ways in which adhesives and sealants can be applied. Below we will go into the different ways of application of these adhesives and sealants and some of their benefits:

bare bus body structure supported by adhesives and sealants in bus assembly
Adhesives and sealants in bus assembly are crucial to body structures as they replace mechanical fasteners and improve performance.
  • Assembly of body structures: Sealants and adhesives can lessen the risk of corrosion as well as the ingress of water and standing water, thereby simultaneously contributing to the passengers’ comfort due to it dampening sounds and vibrations.
  • Interior design: The appearance of the bus will be improved upon due to adhesives and sealants leaving no visible traces behind after their application. The most common adhesive used in bus interiors allows for extremely fast processing, because it is hot melt: hot melt becomes liquid when it is heated and hardens when it reaches room temperature.
  • Floors and side panels: The use of modified silicone polymers leads to a higher resistance against extreme temperatures and weather conditions. That is because these seals are watertight and resistant to various chemicals. These applications are bonded with adhesives made of elastic polyurethane, which are often used in trains as well as buses. The dampening effect of these adhesives mentioned before also means that in the unlikely event of a crash the impact is dampened leading to an increase in safety.
  • Bonding of the roof: Bonding the roof with sealants and adhesives instead of mechanical fasteners leads to a reduction in weight on the roof, which improves the balance and makes for a streamlined design. This also applies to the front and rear masks of the bus as well as antennas installed on the roof.
  • Direct glazing: Glazing the buses’ surfaces with adhesives and sealants is a great choice to reduce costs by shortening the production time since many of them are fast-curing products. This means that they dry quickly which speeds up the production process and even more so because this process can be automated. Furthermore, glazing with adhesives and sealants offers protection against moisture ingress and an increase in aerodynamics.

Greener adhesive and sealant solutions for buses

Bus manufacturers have been looking more into environmentally friendly options for the interior and exterior designs of buses. It is therefore not surprising that many manufacturers have started to use sealants and adhesives. While sealants and adhesives are not really affected by the environment, e.g. harsh weather and wind, there are many which also make little impact on the environment. We will look into modified silicone polymers which are commonly used as a green solution in the production of buses.

MS Polymers are sealants which consist of one component, making them easy to process. These glues do not consist of solvents or isocyanates that can be considered detrimental and their volatile organic compound is either zero or near zero. There has been a growing demand for MS polymers and they are mostly used in the sealing of buses’ body structures. Next to that they are also fairly often used to direct glaze buses.

We will help you buy the best products for your bus!

It is important to look into all the options and choose the right products that fit your bus. Hopefully this article has given you a clearer picture of what possibilities there are and which you might be interested in. However, if you are still unsure do not hesitate to contact us! Even if you have already made up your mind we are happy to help you get what you need so your passengers as well as you can enjoy your bus to the fullest!

Increase of adhesives and sealants in road transport industry

There has been an increase in the use of sealants and adhesives for vehicles that transport cargo or people on the road. This increase is due to adhesives and sealants being more advantageous solutions compared to other sealing and bonding options. These adhesives and sealants have been used for agricultural vehicles like tractors to public safety vehicles such as ambulances. They are also used for recreational vehicles like campers and caravans.

In this article we will give information regarding the use of adhesives and sealants for transportation vehicles on the road.

The advantages that come along with adhesives and sealants

The vehicle industry with its eye towards the future chooses to use innovative materials that will improve durability and the efficiency of the production of vehicles. Therefore, many manufacturing facilities for vehicles opt for sealants and adhesives instead of traditional alternatives. The advantages of the use of adhesives and sealants for road transport are:

  • Shock absorption and noise cancellation: these sealants and adhesives can absorb shock as well as cancel out noise. Shock absorption especially can be useful during the production process.
  • Lower chances of corrosion: traditional fasteners are mostly made out of metal which leads to more corrosion because of the metal-to-metal contact. This is prevented with the use of adhesives and sealants, which lessens the chances of corrosion happening.
  • Pressure is spread out: traditional fasteners put extra pressure on certain spots, while adhesive and sealants are sprayed upon the surface and spread out more which leaves the surface with less of an uneven stress spread.
  • Protects the material: adhesives and sealants unlike fasteners such as screws, do not require holes or other damage to be done to the material on which they are used.
  • Easy and fast to apply: systems of adhesives and sealants can easily be part of the production process and can be automated.
  • Lighter weight: by using adhesives and sealants that are light, almost no weight is added to the total weight of the vehicle. This follows the trend in the industry of road transport which is leaning towards using lighter materials.
  • Visually appealing: it is possible to get adhesives or sealants in various colours or even paint over them.

Sealing and attaching of materials in road transport vehicles

Sealants and adhesives made for use in road transport offer a wide variety of ways for application from buses to fire trucks to bulldozers. They offer more strength and high elasticity and durability. Some even offer high chemical or temperature resistance that are needed in harsher environments.

truck front and windshield with road transport adhesives and sealants
Road transport and sealants have long been used for sealing and bonding vehicle windshields.

These road transport application systems consist of adhesives, sealants, adhesive sealants as well as sealers which can be used for the following:

  • Seals: the sealants can be involved in the sealing of welds, panels, chassis, bodywork or the interior like the floor and roof. MS polymers are a common choice of sealant in many applications in road transport vehicles.
  • Bonds: structural bonding of the panels, bodywork, roofing and flooring is often done with the use of adhesives. Adhesives are also suitable for attaching antennas and other receivers.
  • Windows: all but the coatings are mostly used for the sealing and bonding of windows for road transport vehicles. It can be used for windows made out of mineral glass or plastics such as poly carbonates.
  • Floor coating: to increase durability of the floor of vehicles an appropriate floor sealer can lead to optimal results when used with the correct primer.

Certified adhesives and sealants for road transport

Road transport consists of many different types of vehicles, which each is meant for a certain purpose and environment. Therefore, product certification is of great importance when choosing sealants and adhesives. These certificates can also be relevant to other vehicles than road transport, for example, railway vehicles which can operate in a similar manner. Some of the certificates that we consider quite relevant include Wheelmark, FMVSS 212, ISEGA and DNV GL.

Wheelmark assures that the product has a high durability and performs well in harsher environments. These might even be certified for use in ship building and repair, because of following the requirements set by the EU for maritime equipment.

Federal Motor Vehicle Safety Standard (FMVSS 212) is a certification that assesses the product’s performance in a crash situation and looks at the windshield and window’s strength and durability in connection to the seals and adhesives used.

To see if a product is safe to use in any aspect related to food or its distribution you have to look for an ISEGA certification. This certification along with HACCP is needed for seals and bonds used in road transport vehicles that contain food, because they have the lowest risk of food contamination.

For functional safety on the road DNV GL is relevant. It is a certification that assesses road transport products according to international and various European standards. Standards that are included are reliability, maintainability, availability and (system and software) safety.

Long lasting results with masonry veneer mortar

Masonry veneer is a very popular choice for interior and exterior walls as well as fireplaces and numerous other applications. It creates a stone or brick like surface but provides better economy and offers more possibilities for sufficient insulation. The key to successful masonry veneer installation is divided to veneer type, professional workmanship and high quality materials including masonry veneer mortar (or adhesive), water and air barriers as well as pointing mortar.

Traditional vs. modern masonry veneer installation systems

The most common reason for failure of masonry veneer installations is delamination caused by water intrusion. Poor choice of water and air barrier materials and masonry veneer mortar may encourage water intrusion. Therefore, the choice of these materials should be carefully thought through.

Traditionally, the veneer installation process starts with two layers of felt paper on which metal lath is installed. The lath is coated with a mixture which consists of regular sand and masonry cement. The veneer is placed on the prepared substrate by applying masonry veneer mortar to the back of the tile before placing it its spot. The tile must be held in place to make sure it sticks. It cannot be moved once it is put on the substrate. The problem with the traditional masonry veneer adhesive is its strength which is not suitable for heavy duty vertical bonding. Fortunately, masonry veneer adhesive mortars have been developed especially for this purpose.

Polymer enhanced mortar for masonry veneer

The more modern technology for masonry veneer adhesive includes polymer enhanced systems which overcome the two issues experienced when working with traditional mortar: delamination by water intrusion and poor bonding strength on vertical substrates.

Instead of regular sand-cement mortar, the substrate should be prepared by applying two or more coats of air and water barrier in order to create a membrane that does not let any air or moisture through. Get more information on suitable air and water barrier products by contacting us.

masonry veneer mortar applied to stone veneer on an unfinished wall
Masonry veneer mortar can be applied onto the back of the tile which is then placed onto the substrate.

The polymer enhanced masonry veneer mortar comes in a powder form, much like regular mortar, and it is mixed with water prior to application. The masonry veneer adhesive can be applied in two ways:

  1. Back of the tile: first a skim coat is applied to the back of the tile followed by a thicker layer of mortar. The tile is then placed on the substrate, slid an inch or two from its place and moved back to the final position. This is done to ensure good adhesion.
  2. Mortar bed: a faster method of working is when the veneer mortar is applied on the substrate and the skim coated tiles are pressed on it. Also when using this method, the tile should be slid back and forth from its place to guarantee adhesion.

Technical information, product suggestions and training possibilities are available upon request.

Benefits of polymer fortified masonry veneer adhesive

The polymer enhanced mortar systems for veneer have several properties that make them the go-to choice. The most remarkable benefits include:

  • No sagging: regardless of the application method, polymer fortified adhesives do not cause the masonry veneer to sag guaranteeing long lasting results on facades, fireplaces and other vertical surfaces.
  • Antimicrobial: especially the mortar systems approved for exterior use are often resistant to microorganisms, which prevents growth of mold and mildew.
  • VOC free: most mortar systems come as a powder which is mixed with water. The systems cure as the water evaporates. No solvents are involved in the process, which results in zero VOC products.

Buying masonry veneer mortar of quality

One of the most important factors that encourage successful masonry veneer installation is the type of mortar used to bond the tiles to the substrate. If you are looking for a high quality masonry veneer mortar system, do not hesitate to contact us. Our experts are happy to help you find the right products for your project.

MS polymer adhesives and sealants make transport vehicles greener

MS polymer adhesives and sealants, also known as silyl modified polyethers, were developed in Japan in the 80 ́s. Since then MS polymer adhesive and sealant systems have spread to North America, gaining more and more share, also in the transport vehicle industry including manufacturing of buses, trucks, trains and agricultural machinery.

The need for MS polymer adhesive and sealant systems is ever-growing mainly due to their environmentally friendliness. These systems do not contain silicone, solvents and isocyanates.Naturally there is more to it: exceptional properties, advantages to alternative and broad range of possible uses make MS polymer the go to solution in transport and vehicles industry.

Benefits of using MS polymers in transport vehicles

MS polymer belongs to the group of silane modified polymers: the other type is SPUR polymer. MS polymer is usually preferred as a sealant is it is more elastic and slightly less resistant than SPUR polymers. Nevertheless, MS polymers are also used in high performance adhesives.

MS polymers combine the benefits of polyurethane and silicone based systems at the same time cancelling most of their disadvantages. Below we list some of the general advantages of MS polymer adhesive and sealant systems which make them suitable for transport and vehicles.

train assembly with ms polymer adhesives and sealants
MS polymer adhesives and sealants have multiple properties that benefit the transport and vehicles industry.
  • Watertight: when absolutely waterproof seals and bonds are required, MS polymer based systems do the job.
  • Chemical resistant: especially in vehicle manufacture, it is crucial that seals and bonds resist certain chemicals such as fuels and cleaning substances.
  • Environmentally friendly: one of the most important benefits of MS polymers is that they do not contain silicone oil, isocyanates or solvents.
  • Flexible: MS polymers are extremely flexible and therefore, suitable even for the most demanding elastic bonding and sealing solutions.
  • Weatherproof: important for vehicles that are continuously exposed to the elements, MS polymers are weatherproof lasting significantly longer than for example polyurethane.
  • Easy to process: most MS polymer adhesives and sealants do not require any surface preparation, which increases process efficiency. They also adhere to most substrates without pretreatment and bond and seal dissimilar materials.
  • UV resistant: compared to silicone and polyurethane sealants and adhesives, silyl modified systems are more UV resistant and require less maintenance when applied to vehicle parts exposed to UV rays.

No silicone, solvents and isocyanates

MS polymers do not contain any silicone, solvents or isocyanates unlike polyurethane and silicone based products they are often compared to. These three ingredients are common in chemical products as they improve workability in some cases. They are, however, also hazardous as for example isocyanates are classified as possible human carcinogens, solvents may cause respiratory problems and silicone can lead to skin irritation. These ingredients may also contribute to problems in developing seals and bonds. Note that even though MS polymer adhesives and sealants are silicone, isocyanate and solvent free, they remain chemicals and require safety measures to be taken when worked with.

The absence of solvents, silicone and isocyanates also provide significant benefits:

  • No bubbling: when a sealant or adhesive is applied, it comes in touch with moisture in the ambient and in the substrate. If the system contains isocyanates, bubbling is possible due to the isocyanates reacting with water and releasing co2.
  • No staining: some sealants tend to cause staining. This is usually due to silicone oil, which is not used in MS polymer adhesive and sealant systems.
  • Applicable to damp substrates: due to the absence of isocyanates allows for application on damp or wet substrates.
  • No shrinkage: solvent based systems usually shrink as they cure through solvent evaporation. 100% solid MS polymer systems do not suffer from shrinkage.
  • Paintable: MS polymer can be painted with most water based paints. This is not an option when the system contains silicone.

Choosing grout and glue for marble tiles

Marble is a hard and compact yet delicate natural stone which can be used to give a room a hint of luxury or create a special ambient. Marble is commonly used as floor or wall tiling. In this article we are taking a closer look at the needs of a marble tile, and how to define the best grout and glue for marble tiles.

Marble tiles require special attention

Marble is a metamorphic stone which is formed as a result of crystallization of limestone caused by extremely high temperature. The tiles are recognized by their extraordinary vein-like texture which are sheets or plates of crystallized minerals. As marble is a natural stone, laying marble tiles require special attention regarding several aspects:

different colors of marble times waiting for glue and grout
Marble tiles come in many colours: in the US and Canada the light colors are the most popular.
  • Porosity: as marble is formed under high temperature, it has a hard and compact structure as well as a smooth, rather non porous surface. Due to the non porosity there are multiple options for grout and glue for marble tiles.
  • Movement: even though marble tiles are not very porous, they can expand when subject to high temperature, or temperature fluctuations, like in the case of floor heating, or extreme humidity like in bathrooms. The possible movement, or expansion, of the tiles must be considered when choosing grout and glue for marble: one should opt for flexible glue and grout in order to prevent the tiling from failing.
  • Color: Marble stone comes in a range of colors, however, in the US and Canada the black and white shades are the most popular. When choosing glue and grout for marble tiles, the color of the tile sets some limits. White and other light colored tiles should always be granted a white tile adhesive in order to prevent a darker color from shining through and darkening the tile´s appearance. The choice of grout also affects the visual appeal of the tiling. The grout can either be matching with the tile color or contrasting.

The right glue for marble tiles

When choosing a tile adhesive for marble tiles it is important to picture the tiling. Marble tiles are often also dry laid before the actual tiling takes place in order to guarantee the veins form a desired pattern on the finished tiling.

Earlier we have distinguished between three types of tile adhesive for natural stone, in the case of marble, all of the options are available. However, if choosing for a cement based tile adhesive, this should be thin set instead of thick bed. Cementitious tile glues are suitable for most marble tiling applications, horizontal and vertical. Nevertheless, when the tiling is likely to be subject to temperature extremes or fluctuation, a slightly more expensive construction epoxy should be considered. On the other hand, if the tiles may be affected by humidity, a polymerized adhesive offers a considerable option. Like epoxies, polymerized adhesives are also flexible and can withstand possible movement extending the life expectancy of the tiling.

Marble is also a common material of veneer. There is a special mortar for these applications.

Grouting marble tiling

Once the marble tiles have been set to their place with adhesive, it is time to grout the seams in order to seal and fill them. Before grouting, the tiles should be cleaned and sealed in order to create a protective layer on the tiles. The sealer not only protects the tiles from the grout but also later from dirt and staining.

There are primarily two types of grout for natural stone, further divided into sub-types of grout. Both cementitious and epoxy grout are suitable for marble with some precautions. Cementitious grout is by far the most common option for natural stone. It exists as sanded, non sanded and latex modified variations. The latter more flexible than the others. non sanded grout is more popular than sanded grout as marble tiling usually has narrow seams. In case your tiling involves wide seams, and you decide to use sanded grout, be aware that the sand in the grout may scratch the surface of the tile.
An epoxy grout is more expensive than cementitious grout, but it is easier to clean and keep clean, does not require maintenance next to cleaning and it resists humidity and chemicals better. Epoxy grout is also somewhat flexible and therefore, suitable for tiling that may experience movement. There are also superior pre-mixed grouts that have very similar properties to epoxy grout.

Choosing the right type of grout for natural stone tiles

In a natural stone tiling project, once the tiles are put in place using tile glue, the gaps between the tiles must be filled and sealed. This is done by applying a grout for natural stone tiles. The purpose of the grout is to seal and fill the caps, but also to make the seams impermeable to water to prevent liquids seeping to the tile glue layer. The grout also holds the tiles in their place and creates a supportive network over the tiled area.

Especially when working with natural stone tiles, choosing the right grout for tiling is of high importance. The wrong choice of grout may lead to ruined looks of the tiling or failure of the tile installation, in the worst case. So how to choose the best grout for natural stone tiles? Generally, you can’t go wrong if you keep in mind that the tile or stone, adhesive and grout all need to be compatible with each other. However, it is not always that simple. Here you will find some considerations regarding grout for natural stone tiles as well as the most common types of grout.

What to consider when choosing a grout for natural stone tiles?

Natural stone tiles are known to be rather difficult to work with due to their sensitive nature, possibly light colour and porous structure. Some factors that affect the choice of grout for natural stone include the following:

  • Gap width: some tile grouts are designed for wide gaps whereas others can only be applied in narrow gaps due to shrinkage.
  • Hardness of the tile: if the tile has a shiny or extremely soft surface, some grout types may actually scratch the surface, ruining the looks.
  • Porosity of the tile: very porous tiles may become stained by the grout. Fortunately this problem can be overcome by protecting the tiles with a sealer or grout release substance prior to grouting.
  • Tile color: when working with tiles that require a grout of a certain color, some grout options are available. Not all of them come in colors other than white and grey.
  • Tiling location: one must also consider whether the tiling is applied horizontally or vertically, indoors or outdoors, in a high foot traffic area such as a hallway or less used areas such as bathrooms.

The types of grout suitable for natural stone tile installations

Just as there are many types of natural stone tiles (such as granite, marble, slate, limestone etc.) and adhesives, there are various types of grout. The types of grout can generally be divided into cementitious and non cementitious, of which the most common in North America is epoxy. Here we introduce the most popular grout types for natural stone tiles.

Cementitious grout / mortar

The oldest and still by far the most popular grout, also in the US and Canda, is cementitious grout which uses Portland cement as its main ingredient. The other ingredients include filler particles of different sizes and materials depending on whether the grouting system is sanded or non sanded, a water retentive additive and pigments that create the color. It is also possible to strengthen the cementitious grouts by adding ingredients such as latex.

The cementitious grout, also known as mortar, comes in a form of a powder which is mixed with water prior to application. After mixing, the mortar should be let stand for 10 minutes and then be mixed again to make sure no dry material remains in the mixture. The mixing should always be done by hand rather than with electrical equipment.

Cementitious grout exists as sanded and non sanded variations which can both be applied to natural stone tiling. It is important to keep in mind that mortar seams need regular cleaning and sealing due to their somewhat porous nature which makes them prone to dirt and staining.

A sanded cementitious grout for natural stone is needed for wide seams.

Sanded cementitious grout

Sanded cementitious grout, as the name implies, contains sand. The sand in the systems makes it stronger and prevents cracking. Therefore, suitable for wider gaps. The general rule is that sanded mortar should be used when the gap width is ⅛ inch or wider. When working with natural stone tiles, it is important to keep in mind that the sand can actually scratch the surface of the tile. Always test the grout on a sample tile to guarantee compatibility.

Non sanded cementitious grout

The non sanded grout has much smoother a texture than sanded grout. Non sanded grout contains mineral particles that are very fine and do not provide a grit structure. Also non sanded grout is common for natural stone tiling, however, it may stain the tile if the tiles are not protected by a sealer prior to grout application.

Non sanded grout is ideal for narrow seams from 1/16 inch to 1/8 inch. This because of the fact that non sanded grout shrinks as it cures. When applied to wide seams, more mortar is used hence the shrinkage is greater making the grout pull away from the tiles.

Latex modified sanded grout

It is possible to increase the performance of sanded cementitious grout by adding a latex polymer. The polymer can be added into the grout powder or as a liquid while mixing the powder with water. The addition of latex polymer remarkable improves the waterproof properties of sanded grout.

Epoxy grout

If you are looking for the best grout for natural stone tiles, epoxy grout makes a good candidate. However, it is also the most expensive type of grout and not always worth the investment. Nevertheless, epoxy grout is the strongest option available, and it is completely impermeable. Epoxy grout consists of epoxy resin, silica fillers, pigments and a hardener. The systems can be two or three component grouts. Natural stone tiles should be sealed prior to grouting to avoid staining.

Also epoxy grout comes as sanded and non sanded variations, yet the sand is not the same kind of sand as used in mortar. Both types of epoxy grout are resistant to water as well as chemicals making them ideal for areas such as kitchens. Even though epoxy may seem like a perfect solution, the application requires expertise as epoxy grout cures fast compared to cementitious grouts. Once the components have been mixed, the curing process starts.

TIP: after mixing the components, divide the grout in two containers and put one of them in the freezer. The low temperature slows down the curing process giving you extra time to finish grouting.

As epoxy grout forms impermeable seams, it is not necessary, nor recommended to seal the grout. In case the grout shows signs of dirt or staining, it is best cleaned using vinegar or bleach and water.

Epoxy hybrid grout

Epoxy can also function as a ingredient of a hybrid grouting system. Most commonly epoxy grout is reinforced with Portland cement. This hybrid results in seams similar to those made with cementitious grout. They require regular sealing but are stronger, harder and more stain resistant than regular mortar.

Adhesives for natural stone tiles guarantee neat tiling

Natural stone tiles are extremely popular in interiors and exteriors as they exist in many types, each creating a special atmosphere to the area or space. Nevertheless, natural stone is not the easiest material to work with: when laying the tiles, a special adhesive is needed. There are plenty of adhesives for natural stone tiles, but not every stone type requires the same adhesive.

The right natural stone tile adhesive makes sure the tiling is flawless, and guarantees faster and easier application. However, the wrong choice of an adhesive can result in failure by affecting the physical or visual properties of the natural stone tile. Therefore, it is crucial to choose for the best possible adhesive for the specific type of natural stone.

How to choose an adhesive for natural stone tiles

Natural stone tiling can be the key to creating a specific atmosphere, however, laying the tiles needs special attention especially in regards of the adhesive that keeps the tiles in place. As there are different types of natural stones, there are also many adhesive options, yet not every adhesive suits every stone type. When choosing the best tile adhesive for natural stone, some important questions should be answered.

1. What is the surface made of?

The first factor to consider when choosing an adhesive for natural stone is the substrate the stones or tiles will be laid on. What material is the substrate made of? Is it porous or absorbent? Can it carry the weight of the tiles? These are all factors that define which natural stone adhesives can be used on the specific substrate. Find out what type of adhesive your substrate requires!

Always study the adhesive manufacturer ́s advice on suitable substrates and tiles in order to avoid costly mistakes.

2. Which type of natural stone is used?

The term natural stone tile covers all tiles made of natural stone. These can be divided into three groups: calcareous, non-calcareous and slate stone:

  • Calcareous natural stone: stone types that contain calcium carbonate like limestone and marble and some sandstone types.
  • Non calcareous natural stone: natural stone types that do not contain calcium carbonate including granite, sandstone and basalt.
  • Slate: metamorphic stone formed over a long period of time. Results from a mix of other stone types and minerals.

The most important difference between the stone types regarding the choice of adhesive is its porosity. Porous natural stone tiles such as limestone and sandstone require an adhesive that does not get absorbed into the pores of the tile. Non porous tiles such as marble and granite can be bonded with a wider range of adhesive types. Also the color of tile matters as a light colored or translucent tile (marble and limestone) should never be combined with a colored adhesive. The adhesive layer can show through the tile affecting the hue of the finished tiling.

3. In what kind of environment are the stones or tiles laid?

The most common natural stone tile applications take place on walls and floors. However, these two applications cannot be completed with the same adhesive. Walls require vertical bonding, which is why the adhesive must be strong enough to hold the tiles in place even when the adhesive is not fully cured. Also the weight of the wall tile affects the choice of adhesive. When laying natural stone tiles on floors, the air need of the adhesive must be taken into account. Most adhesives for natural stone tiles need air to cure, however, for floors other means of curing are more beneficial as there is not much air under floor tiles.

The choice of adhesive is also affected by whether the tiling is placed inside or outside. Especially exterior tiling needs attention as the application conditions, temperature and humidity may vary. The conditions should be neither too hot nor too cold and the humidity percentage should be within the given range. Not only is the application important, but the required durability of the adhesive should also be considered: exterior tiling is exposed to the elements as well as temperature extremes and drastic fluctuation requiring strength and flexibility from the adhesive.Interior tiling is more forgiving in terms of the adhesive: the application conditions are not likely to exceed given norms, nor is the tiling likely to be subject to temperature fluctuation or the elements. Note that flexibility is required from the adhesive especially when tiling is laid on floor heating.

Extra: to what extent is maintanance needed?

Regardless the stone type or the tile adhesive, natural stone requires maintenance from time to time. Cleaning, protecting and careing fro the natural stone should be carried out with products designed for the purpose. The products for natural stone care can be divided into two grouops:

  1. Sealers: especially porous natural stone surfaces should be trated with a sealer as they are prone to dirt and debris, which may harm the visual or physical properties of the stone. A sealer reduces the need for cleaning the tiles and prevents irreversible staining.
  2. Cleaners: available for all natural stone types, cleaners remove dirt and stains from the tile or stones as well as from the grout between the stones. Make sure to use a cleaner that is designed for the specific stone type to prevent damage.

Types of adhesives for natural stone tiles

The adhesives for natural stone tiles are numerous, and when used correctly they all can result in fast and efficiently applied, durable and stunning tiling. Here you can find the three most common types of adhesives for natural stone tiles. Keep in mind that these are not the only types: contact us and get more information on the adhesive options.

  1. Cement-based tile adhesives: cement-based adhesives, also known as mortar, come in two types: thin set and thick bed tile adhesives. These can be used for laying most natural stone tiles as long as they are non porous like marble and granite. The common color options are white and grey.
  2. Construction epoxy: epoxy is among today’s strongest adhesives. In the right formulation high strength construction epoxy can also be used on natural stone tiling. Epoxy is usually flexible, which make the adhesive ideal for exterior tiling.It is not likely to be affected by temperature fluctuations or extremes.
  3. Customized polymer adhesives: as polymer adhesives are versatile and easily modified, they are also suitable for natural stone tiling. Especially flexible polymerized adhesives benefit natural stone. The adhesive formulation can also be easily customized to fit the purpose perfectly.

There are also tile adhesives with special properties such as heat resistance, in case of floor heating, sound insulation for floor and wall tiles as well as special adhesives for humid areas such as showers and dressing rooms.

Choose for flexibility when floor heating is involved

Floor heating and natural stone tile adhesive
Regardless the type of floor heating, the tiling on it should be installed using flexible tile adhesive.

In the US and Canada, floor heating is becoming more and more popular. Small surfaces are usually heated using electric floor heating, whereas larger surfaces are heated using warm water pipes. In both cases, it is recommended to use a flexible tile adhesive as the heat source is close to the tiles and may cause movement.

Floor heating can be installed on new underfloors, which are tiled afterwards, or on old concrete or tile floors which receive a new tiling on top of the heating. Also in these cases a flexible tile adhesive yields the best results. Contact us for advice on the best tile glue.
