COLOUR-FAST GROUT is a fast-setting, polymer fortified, mould resistant grout based on lime-free binder technology. This ensures the finished colour shade is consistently achieved without being affected by efflorescence or shade variation. It is available in a range of 3 colours for wall & floor tile joints up to 20mm wide. It is an easy to mix, readily compactable grouting compound which can be applied across all types of ceramic tiled surfaces using a sponge or rubber squeegee
