Palace Tile-Grout is an ultra-fine cement-based grout making it ideal for narrow joints up to 3mm wide around all types & sizes of wall tiles. It mixes to a super-smooth, non-slump, readily compactable paste, which can be applied over mosaic, ceramic and porcelain tiled surfaces using a sponge or rubber squeegee. Where substrate movement is likely, the recommended alternative is Palace Anti-Mould Wall and Floor Grout which is polymer reinforced to provide greater stress resistance.
