The BS EN classification for ARDEX-FLEX FL is CG2 WA, an “improved cementitious grout with additional characteristics of reduced water absorption and high abrasion resistance”.

ARDEX-FLEX FL is suitable for grouting joints from 3mm to 15mm wide, between porcelain, ceramic, non-moisture sensitive natural stone and quarry tiles, as well as extruded tiles and glass blockwork.

The hardened grout is weather resistant, unaffected by water and can be used for internal and external tiling in dry and wet locations, including swimming pools with non-aggressive water conditions.

ARDEX-FLEX FL can be applied to both wall and floor tile joints. The freshly applied grout mortar can receive foot traffic after 90 minutes at 20°C.

Where chemical spillages or corrosive liquids are likely to be in contact with the tile joints, use either ARDEX WA Epoxide Adhesive and Grout or ARDEX EG 8 PLUS Epoxide Adhesive and Grout.
