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.
Before ceramic tile application on existing tiles in wet areas such as bathroom, shower, WC etc., Izoline 100, which is a 3 layer extra elastic waterproofing membrane that is composed of modified polyethylene films laminated in between polypropylene seals with high alkali resistance, should be applied. Kalekim Waterproofing Tape (Type III) and Izoline 100 Complementary Components should be installed with 1059 Ultratech tile adhesive mortar (minimum C2 and S1 class) at critic areas such as existing tile floor wall and corners, pipe details (inner corner, outer corner, pipe and drain cuffs).
Depending on the area to be applied, Izoline 100 waterproofing membrane is cut to appropriate sizes and installed on 1059 Ultratech ceramic adhesive mortar (minimum C2 and S1 class) applied with by means of a 4 mm or 6 mm notched trowel. 100% surface adhesion of Izoline 100 should be ensured by removing the excessive mortar underneath by applying force from the center to the edges by means of a trowel in a way that no air bubbles remain on the surface. When applying Izoline 100 side-by-side, two membranes must be overlapped by at least 5 cm and these parts must be fixed together with the ceramic adhesive used for bonding.
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
In cases where no immediate ceramic tile application will be made on Izoline 100, the surface must be protected from direct sunlight and rain. Upon completion of Izoline 100 application, ceramic application can be started without waiting. 1059 Ultratech, the quick setting tile adhesive mortar with S2 class, should be used for tile application. Regarding the grouting mortar application, 2500 Ultrafuga Flex grouting mortar, which features both water repellency and flexibility, will be a perfect system complement in the bathrooms.
