Solutions for Waterproofing & Ceramic Tile Application on 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.



Waterproofing Application

3024 İzolatex Plus, which is a two component, flexible, under-tile waterproofing material should be applied before tile application on underfloor heating systems in wet areas such as bathroom, shower, WC etc. Existing tile floor wall and corner joints should be reinforced with Kalekim Pah Bandı (Waterproofing Tape) (Type III). The tape should be placed carefully on the waterproofing material, the first layer of which has been applied with a brush or a roller, in a way that the center of the tape matches with the joint. The second layer should be applied after waiting for 5-6 hours between layer application depending on the ambient temperature. After the surface dries, it must be waited for 7 days for full setting and leak-tightness tests should be carried out for 24 hours.

Tiling and Grouting

High performance, flexible (S1), cement based adhesive mortar 1054 Technoflex, which is resistant to surface tensions taking place due to the temperature changes in underfloor heating systems, should be used in ceramic bonding application on waterproofing material. 2500 Ultrafuga Flex high performance grouting mortar, which is resistant to dirt and flexible thanks to its silicone additive, should be applied for the application of a long-lasting grouting mortar in continuously wet areas such as bathrooms, showers, WC.
