ARDEX F 4 is a cement-based fine grouting compound for ceramic wall tiles and mosaics where the joint width does not exceed 4mm.
The BS EN 13888 classification for ARDEX F4 is CG2A, an “improved cementitious grout with additional characteristic of high abrasion resistance”.
The powder is mixed with water to produce a soft, creamy and easily worked
mortar with good filling properties, allowing joints to be completely filled in one operation.
The hardened ARDEX F 4 joint is smooth, weather resistant, unaffected by water and can be used for internal and external tiling in dry and wet conditions, including swimming pools with non-aggressive water conditions.
