In recent years, large-format ceramic and granite tiles have rapidly become widespread in architectural designs. Tiles in sizes of 60x120 cm, 120x120 cm, and even larger are now becoming standard even in residential projects. However, this change also brings new technical requirements regarding the selection of ceramic adhesives
Unfortunately, classic ceramic adhesives are still used in many applications. This can lead to serious problems in coating systems over time.
Why are large ceramic pieces more difficult to work with?
Large ceramic tiles have a much greater weight and surface area than standard coatings. This places a higher load on the adhesive.
In addition, the following problems are more common in large coatings:
-
surface tension
-
thermal expansion differences
-
void formation
-
loss of adhesion
Therefore, high-performance ceramic adhesive systems should be used for large-scale coatings.
How to Choose the Right Adhesive?
When selecting construction chemicals to be used in large-scale ceramic applications, certain technical criteria must be taken into consideration.
The following features are particularly important:
-
high adhesion value
-
flexible structure
-
long open waiting time
-
shear resistance
Ceramic adhesives with these properties allow the coating system to move with the substrate and prevent chipping that may occur over time.
Surface preparation is just as important as the adhesive itself
One of the biggest mistakes made on construction sites is neglecting surface preparation. Applications on dusty, loose, or excessively absorbent surfaces can cause problems, even when using the highest quality ceramic adhesive.
Therefore, before implementation:
-
Surface cleaning should be done
-
If necessary, primer and undercoat products should be used.
-
Surface smoothness should be checked.
If surface preparation is not done correctly, voids and chipping problems may occur in coatings over time.
Joint Filler Selection is also Part of the System
In ceramic applications, another element as important as the adhesive is the grout system . Properly selected grout products increase the flexibility of the coating surface and reduce water penetration.
Grout sealants, especially those used in areas like bathrooms, balconies, and terraces, also contribute to waterproofing performance
Why is using the right system important?
Construction chemicals are not products that should be evaluated in isolation. Ceramic adhesives, grout, and surface preparation products together form a system.
Using the right products together:
-
extends coating life
-
reduces maintenance costs
-
minimizes application errors
Therefore, in large-format ceramic applications, selecting the correct construction chemical system is one of the most critical factors directly determining coating performance.
