Product Question & Answers for - Norcros Adhesives 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/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. The adhesive has a setting time of 2 hours at 20oC permitting early trafficking of the tiled installation. When cured, the adhesive achieves comparative strengths to a conventional C2 cement-based adhesive.
