ARDEX FS-DD is a non-sanded cement-based, wall and floor grouting compound which is specially designed to be water and dirt resistant making it ideal for wet areas such as showers. ARDEX FS-DD is easy to apply and fast drying, with final cleaning able to be completed 24 hours after initial wash off with no residue left on the tile surface. The hardened grout is exceptionally easy to keep clean and will maintain its appearance as no water and dirt residue can seep into the grout joints. It is further protected from mould growth due to the addition of ARDEX Grout Shield which combats fungal and algal growth.
