Low-chromate to Regulation (EC) No 1907/2006, Annex XVII.
A polymer-modified, cementitious medium- and thick-bed tile adhesive for up to 30 mm coat thicknesses. Sopro MDM 888 is particularly suitable for laying large-format ceramic tiles, fully vitrified stoneware and suitable discoloration-resistant natural stone coverings using medium- and thick-bed method on dimensionally stable (e.g. cement or calcium sulphate screeds) and substrates with limited deformation, e.g. heated screeds, (min. 3-month-old) in-situ concrete. High crystalline water-binding capacity of Sopro MDM 888 reduces discoloration of natural stonework by mortar.
