Solutions for Waterproofing & Ceramic Tile Application on Existing Tiles

Surface Preparation

It is important to check the strength of old tiles. If there are any broken or displaced tiles, these tiles should be removed and the gap must be filled with 4002 Tamirart 30 thick repair mortar. If there are structural cracks on the surface, 4004 Tamirart S40 should be used. The empty space can also be repaired by bonding a solid tile. 4506 Kalekim Dolgulu Astar (Smooth Surface Primer) should be used to increase the bonding strength before waterproofing application.


Waterproofing Application

3024 Izolatex Plus, which is a two component, flexible, under-tile waterproofing material must be applied before tile application on existing tiles 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 must be installed 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 must 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 granite adhesive mortar 1055 Granitech should be used in ceramic bonding application on waterproofing material. 2500 Ultrafuga Flex high performance grouting mortar, which is resistant to dirt 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.
