COLOUR-LOCK 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 12 colours (see below) 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. 
COLOUR-LOCK GROUT will dry to a hard, durable, shrink-resistant, mould resistant and water-repellent finish, suitable for internal and external locations and especially in sanitary areas in kitchens, showers, toilets & bathrooms where inhibition of fungal growth is essential. 
Recommended when fixing tiles in challenging locations such as over plywood and heated sub-floors where some minor vibration can be expected.
