There are many factors to consider when laying tile, from proper planning to the right material and a professional approach.
The so-called flexible adhesive or flexible mortar allows you to lay tiles even on difficult working bases, accompanying these movements, prevents cracking and peeling tiles.
Tile adhesive acts as a barrier against moisture and mold and being flexible enough to help maintain the appearance of your home.

What is Tile Adhesive?
Strictly speaking, they are not adhesives at all, because most tile adhesives are mortars. Mortar is usually a powdery mixture that must be mixed with water immediately before use. This powder is composed of binder cement and fillers such as limestone powder or quartz sand. Some tile adhesives also contain plastic additives to make the tile covering more flexible.
Working here refers to minor movements in floors that are not completely rigid, which can cause damage to the tiles if the tile adhesive is inflexible. The tile adhesive is applied to the wall or floor, after which the tiles are positioned on it. Grout is then used to fill the gaps between the tiles. After the curing time, which varies from product to product, the tiles are fixed.
What Are The Types Of Tile Adhesive?
Anyone who has ever wanted to buy tile adhesive has been confronted with a huge selection of products and adhesive categories. There seems to be the perfectly matched tile adhesive for every need. However, much of this is more appearance than reality, because the brands confuse with inconsistent naming, behind which the same types of tile adhesives are largely hidden.
There are several types of tile adhesive:
- Adhesive mortar.
As the name suggests, the largest group among tile adhesives is the mortar. The adhesive mortar is characterized by a high percentage of cement and its powder form. This means you have to mix this type of tile adhesive before you can – and must – use it. This is because the adhesive mortar hardens quickly, so you should get to work quickly.
What appears to be a disadvantage on the one hand has a positive effect on the other that tiles laid with adhesive mortar can sometimes be loaded after just a few hours. The cement adhesive can be used on concrete, screed, and plaster, for example, so there are numerous possible applications.
- Flex mortar.
Flex adhesive is a subcategory of adhesive mortar. The flex adhesive differs in the addition of plastic additives, which ensure that the dried tile adhesive is more flexible, that is, less rigid than ordinary adhesive mortar. Movement of the substrate can be better absorbed with a flex tile adhesive, making tiles less likely to chip or crack. More critical substrates, such as dry screed elements or fiber cement board, can therefore be addressed without worry.
In addition, the flex adhesive has a higher adhesive strength, which means that other critical substrates, in this case very smooth substrates, can be processed. Within the range of flexible adhesives, there are special products such as natural stone adhesive, which can be used to lay natural stones such as granite.
Dispersion adhesives differ from the types mentioned so far. They do not contain a cement component but are manufactured on a plastic basis. Dispersion is plastic particles dispersed in water.
Similar to flex adhesives, they are suitable for strongly working substrates, as they are still extremely flexible even when cured. Due to a very high adhesive strength, they are used especially on smooth substrates. A special feature of dispersion adhesives is that they can be applied directly because they do not first have to be stirred with an agitator.
Since dispersion adhesives cure only very slowly, they are hardly suitable for tiling floors. Another limitation is their lack of frost resistance, which means they can only be used indoors.
- Reactive resin adhesive.
This is a tile adhesive used primarily in commercial applications, as it is a very strong adhesive, but at the same time very flexible and resistant to chemicals.
Reaction resin adhesive consists of synthetic resin and a hardener, which still need to be stirred together before use. The resulting chemical reaction finally hardens the adhesive.
Place the tiles shortly after applying the tile adhesive.
What should you look for when buying the tile adhesive?
Depending on the type of work you will be doing then, some tile adhesives are more suitable than others. So, if you want to lay floor tiles or work outdoors, you should not choose a dispersion adhesive. In this case, an adhesive mortar or elastic adhesive is the right choice. However, if you are installing wall tiles indoors and want to save labor and avoid mixing tile adhesive, a dispersion adhesive is ideal for your project.
If you want to install new tiles without removing the old tiles, first note the product description that the tile adhesive can adhere to the tiles.
When buying should pay attention to the following:
This does not mean flexibility in terms of application ability, but how flexibly the tile adhesive absorbs movement in the substrate. On the one hand, these movements can be caused by the nature of the substrate, such as drywall. On the other hand, they may also be affected by the installed underfloor heating, which in turn requires the use of a flexible tile adhesive. Therefore, in these cases, it is recommended to avoid pure adhesive mortars and use flex or dispersion adhesives, depending on the application.
How much tile adhesive you use depends largely on the product. However, it also depends on whether you adhere to the mixing ratio and how thick you apply the tile adhesive. We advise you to deviate from the specified mixing ratio only if you already have a lot of experience with laying tiles.
- Curing time.
In some construction phases, it is important to obtain fast results and to be able to walk on the floor quickly, for example, to continue working from there. In these cases, dispersion adhesives should be avoided and construction should be based on adhesive or elastic mortars. When looking at individual products, pay attention to the specified curing times, as these can vary greatly even within the category of tile adhesives.
A distinction is made between the time it takes for the tile to grout and be ready for foot traffic, and the time it takes for the tile to be fully loaded again.
- Availability / Availability: Good values here are between 3-12 hours. When the adhesive has cured accordingly, you can, for example, carefully walk over the tiles or briefly load them for grouting.
- Permanent load-bearing capacity: Good values here are in the range of 1-3 days. If the adhesive is permanently load-bearing, heavier pieces of furniture can be placed on the tiles without fear of damage or messy results.

The requirements for tile adhesives are quite high. It is assumed that the tile adhesive will hold the tiles in place for a long enough time in a mandatory manner. The solution should be easy to work with, and it should perfectly fill the gaps between the tile and its base. It should not cure very quickly, as you will have too little working time. That said, if the glue cures very slowly, it will take too long to get to the grouting stage.
Tile adhesives are usually cement-based mortars that must be mixed with water before use. The mortar consists of a binder (tile adhesive cement) and aggregates with a maximum grain size of 0.16in. Additives and agents may also be added. Adding water causes a chemical reaction that hardens the binder.
Tile adhesives have now reached the point where all of these requirements are successfully met and choosing the right tile adhesive is easy.
FAQs- Tile Adhesive
✅ What makes tile adhesive flexible?
Flexibility results from the addition of plastic additives, which enable the tile adhesive to react better to a moving substrate.
✅ When are installed tiles ready to be walked on?
This depends on several factors. On the one hand, tile adhesives have different curing times, and on the other hand, it also depends on general conditions such as temperature or absorbency of the substrate.
As a rule, depending on the factors mentioned above, tiles can be grouted and walked on after three hours at the earliest. Good average values here are also still eight to twelve hours. However, this information should not be confused with the permanent load. It is possible to load the tiles for walking over or grouting, but no heavy furniture should be placed on them yet, for example.
This should only be done when the tiles are fully loadable again, which is usually 24 hours after installation at the earliest. A solid average value is three days – depending on the product, even one to two weeks can pass.
✅ How thick should tile adhesive be applied?
Nowadays, thin-bed mortar is usually used, which is applied at a maximum thickness of five millimeters. However, depending on the tile adhesive and tile format, the medium-bed method with 0.20inс to 0.79inс is sometimes used.
✅ Which tile adhesive to use for laying on cement ?
For working on a cement surface, tile adhesive is better to use a thin-curing mortar.
Before applying tile adhesive to cement, you need to make sure that the surface is free of dust and debris so that the adhesive will stick. Also, the surface of the grout should be level so that there is no slope. A level surface is great for getting the best results.
