Norcros Tile To Gypsum Adhesive
Norcros Tile to Gypsum Adhesive is a fibre reinforced anhydrite based thin bed adhesive designed for the internal fixing of fully vitrified porcelain, ceramic and natural stone tiles directly to gyvlon, gypsum, anhydrite or calcium sulphate-based screeds and gypsum plaster walls with a Relative Humidity (RH) of up to 85%.
Unlike when cement-based adhesives are used, surfaces do not require sealing. However highly absorbent surfaces should be primed using Norcros Prime Bond diluted 1:4 with water and allowed to dry before fixing commences.
Norcros Tile to Gypsum Adhesive has a setting time of 2 hours at 20 degress Celsius permitting early trafficking of the tiled installation. When cured, the adhesive achieves comparative strengths to a conventional C2 cement-based adhesive.
