Which adhesive should be used for large format ceramics?

Large format ceramics are preferred in many projects today, from residential to commercial buildings, thanks to the aesthetic and holistic appearance offered by modern architecture. However, the heavier and larger surface area of these ceramics compared to standard covering materials makes the technical properties of the ceramic adhesive used during application even more critical. Incorrect product selection can lead to slippage, bulging, cracking, and detachment of the ceramics over time, so it is essential to choose high-performance adhesives suitable for the application area.

The adhesives to be used in large format ceramic applications must have high adhesion strength, show flexibility against surface movements, and safely support the weight of the ceramic. Especially in covering materials with low water absorption, such as porcelain and granite ceramics, standard ceramic adhesives may not always provide sufficient performance. Therefore, it is necessary to prefer high-performance ceramic adhesives with improved features that meet the needs of the application area.

For indoor and outdoor applications of large format ceramics, C2 class ceramic adhesives with high adhesion power, reduced slip properties, and extended open time are generally recommended. In areas where temperature changes are intense or where surface movements are involved, using flexible S1 and S2 class adhesives provides significant advantages for the longevity of the application. Especially in underfloor heating systems, balconies, terraces, and areas exposed to heavy use, flexible adhesives help absorb potential stresses, ensuring that the ceramics securely adhere to the surface.

In large format ceramic applications, simply selecting the correct adhesive is not enough. Completing the surface preparation thoroughly, using the appropriate trowel size, and applying the double-sided adhesive (buttering-floating) method are crucial for maximum performance. This application method minimizes the formation of voids behind the ceramics, ensuring that the adhesive spreads homogeneously on the surface. Thus, while the load-bearing capacity of the ceramics is increased, the risks of bulging and detachment from the surface are significantly reduced.
