High performance two-component polyurethane adhesives for ceramic tiles and stone material.
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. Absolutely 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 dimentional 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.
