Deformable cementitious adhesive for stoneware Product description: weber.xerm KM Flex is a flexible, deformable cementitious adhesive with increased adhesion, extended open time and very good working properties. Classification according to PN-EN 12 004 - C2TE S1. Product application: Weber.xerm KM Flex adhesive mortar is used in particular: in places exposed to thermal loads (balconies, terraces, plinths, etc.), on deformable surfaces, exposed to slight stress or slight vibrations, in places exposed to light loads water (e.g. bathrooms, showers), in swimming pools, for fixing tiles on the existing ceramic cladding for use in underfloor heating systems. Weber.xerm KM Flex adhesive mortar is suitable for making wall and floor coverings of ceramic tiles, mosaics, stoneware, stoneware, faience, clinker, tiles, glass mosaic, lightweight building and insulation boards.
