WHERE TO USE

Indoor and outdoor, bonding of wall and floor ceramic tiles, stone material mosaics, etc. on:

▪ screeds, renders, concrete, asphalt, wood, metal, PVC, reinforced polyester, fibre-cement, gypsum, gypsum

board, gypsum panels, etc.

Some application examples

▪ Bonding ceramic tiles, stone material and all types of mosaics in showers and on sheets used for

prefabricated bathrooms.

▪ Bonding ceramic tiles and mosaics on wooden work surfaces or in kitchens in order to achieve a waterproof

substrate.

▪ Bonding ceramic tiles, stone material and mosaics on balconies, external terraces, domes or flat roofs

subject to foot traffic.

▪ Bonding natural stones and reconstructed stone (marble of every type, slate, etc.) also subject to movement

and size variation due to the absorption of water (class C of size stability according to MAPEI standards).

▪ Bonding ceramic tiles and stone material on surfaces subject to vibrations and deflections.

TECHNICAL CHARACTERISTICS

Keralastic and Keralastic T are two-component, solvent and water free adhesives which are flexible and

waterproof. They are made up of a polyurethane base (component A) and a special hardener (component B).

On mixing the two components together, the result is a paste with the following properties:

▪ good workability;

▪ excellent durability and resistant to ageing;

▪ perfect adhesion to all surfaces used in building;

▪ hardens by chemical reaction without shrinkage (until it becomes highly resistant);

▪ high deformability;

▪ in the case of Keralastic T, highly thixotropic: it can be applied vertically without slump and without letting

even heavy or large tiles slip. The slipping strength is in compliance with EN 1308.

RECOMMENDATIONS

▪ Do not use on very damp surfaces or where there is a risk of rising damp.

▪ The packs are pre-measured; therefore mixing errors are impossible. Do not use partial quantities. A wrong

mixing ratio could cause damage during the curing process.

▪ Use the products in temperatures between +10°C and +30°C.

▪ In case of use on surfaces subject to continuous immersion in water, consult the MAPEI Technical Services

Department beforehand.

▪ Do not use Keralastic and Keralastic T to bond transparent glass materials.

▪ We advise against using these products on particulary porous or light coloured natural stones to bond such

materials, use Ultrabond Eco PU 2K.
