MAPEI KERALASTIC Two-component polyurethane adhesive for ceramic tiles

  • Collection: Reaction resin adhesives
  • Type: Two-component polyurethane adhesive for ceramic tiles
  • Two-component, high-performance, polyurethane adhesives for ceramic tiles and stone material. 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.
