DESCRIPTION:
High-performance two-component polyurethane adhesives for ceramic tiles and stone materials.
APPLICATIONS:
Keralastic is an improved reaction resin adhesive (R2). Interior and exterior floor and wall bonding of ceramic tiles, natural stone and agglomerates, mosaic on all types of substrates normally used in building. Particularly suitable for metal, wood, fibre-cement, rubber, PVC and linoleum surfaces. Necessary for bonding natural stone and agglomerates (all types of marbles, Verde Alpi, slate,…) also subject to movement and size variation due to the absorption of water (class C of dimensional stability according to Mapei standards). Applied in a continuous layer, they create a perfect waterproof surface on which ceramic tiles can be applied with the same product. Suitable for surfaces subject to accidental contact with water (for example wooden kitchen work surfaces).
Keralastic T (R2T) is the thixotropic version of Keralastic and is particularly suitable for vertical applications.
CONSUMPTION:
Bonding of ceramics and stone material:
▪ Mosaics and small size tiles (trowel No. 4): 2.5 kg/m²
▪ Normal size tiles (trowel No. 5): 3.5 kg/m²
▪ Large size tiles, marble, stones (back buttering): 5 kg/m².
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.
