Ceramic Tile Application Solutions in Underfloor Heating Systems

Surface Preparation

It should be ensured that the application surface is free of residues that will prevent adhesion, has taken its cure and is sound. It should be ensured that the heating elements are concealed in a screed suitable for underfloor heating systems and have passed all heating tests. Deformation and cracks in the screed, which may occur due to expansion, are controlled. If there deformations or cracks are observed on the screed, these should be repaired with 4002 Tamirart 30 thick repair mortar. 4505 Kalekim Astar (Primer) should be applied before application of waterproofing material in order to balance porosity of the screed surface, to reduce the absorbency and to prepare a homogenous sub-surface.


Tiling and Grouting

In underfloor heating systems, the surface is subject to more movement than normal surfaces due to sudden temperature changes. While the surface is stretched during heating, shrinkage occurs when the system cools down. Only flexible materials can tolerate these movements. Adhesive featuring with minimum of S1 class should be used in the bonding process and flexible grouting mortar should be preferred for grouting. Ceramic tiles should be bonded with Kalekim s flexible adhesive mortar 1054 Technoflex and 2300 Fugaflex flexible grouting mortar should be used for grouting. A properly performed tile application not only contribute to long service life of these systems, but also ensure that they are more efficient.
