A stable, highly flexible cement thin bed mortar to lay ceramic tiles and plates, fine stoneware, porcelain mosaic in interior, exterior and underwater areas. Servolight S2 SuperTec has excellent non-sag characteristics. Due to the very high plastic modification, Servolight S2 SuperTec is perfectly suited to bases with residual shrinkage such as in-situ concrete (at least 28 days old), but also to bases such as gypsum fibre boards, plasterboards, heated screed based on cement or calcium sulphate (pay attention to the corresponding norms and instructions), poured asphalt screed and aerated concrete, as well as flat load-bearing wood chipboard (min. V 100) and OSB boards in dry applications. Suitable for use on balconies, patios and on facades as well as for installation of glass mosaics in underwater applications. Also suitable to compensate for any unevenness in the surface (such as masonry, plaster and screed) up to a layer thickness of 15 mm before tile installation.
