DESCRIPTION

KÖSTER SL Flex is a high quality, fast setting, mineral based underlayment with excellent bonding characteristics also on smooth and dense substrates. KÖSTER SL Flex is applicable to a wide variety of substrates and hardens hydraulically and tension free within a few hours. It hardens to a level, high strength surface that allows for a change in building use, such as carpet or tiles on top of old wooden floors and floor heating. Over wooden floors and floor heating it must have a minimum uninterrupted layer thickness of 10 mm. KÖSTER SL Flex is easy to mix and install, is pump- and pourable, and during its pot life has a low viscosity and is self-levelling. KÖSTER SL Flex can be applied in layer thicknesses between 5 and 15 mm, be feathered out to 2 mm, and installed in depressions up to 30 mm. It hardens quickly and crack free with up to 90 % reduced shrinkage. KÖSTER SL Flex is not intended as a decorative finished flooring. Varying shades due to processing and finishing are considered normal and are covered by the final floor covering, for example carpet, tiles, resilient flooring, or parquet.

AREAS OF APPLICATION

KÖSTER SL Flex is designed for the fast, time saving levelling of uneven indoor surfaces. KÖSTER SL Flex is an early loadable, selflevelling underlayment for concrete, screed, mastic asphalt, tiles, and wooden substrates. It is an excellent material for the repair and levelling of substrates before the installation of tiles, carpet, resilient flooring, and laminates. Wooden board floors on wooden joists can be carpeted or tiled after the installation of KÖSTER SL Flex. Do not install KÖSTER SL Flex on exterior areas or areas around swimming pools
