Mapei Keracolor FF Grout

A fine, polymer-modified cement grout for wall and floor tile joints up to 6 mm wide, inside and outside. A water-repellent treatment means the joints take up less water and dirt and stay easier to clean.

Sold in 5 kg packs, in ten colours. Once mixed it stays workable for about 2 hours, and a grouted floor takes light foot traffic after about 24 hours. Spread it with a rubber grout float and finish with a damp sponge.
