While stirring, pour Colortech into a clean, rust-free container containing 28-30% by weight of water. Mix the grout with a low-speed electric mixer to avoid air entrainment until a smooth mixture is created. Let the mixture to stand for 5 minutes, and stir again briefly before use. Use the mix within 30-45 minutes of its preparation. 

Apply the product with a rubber spatula, directing across the joints, in order to remove the excess of the grout, hold the spatula at a 90° angle and pull it diagonally across the joints. Wait for the grout to partially dry (become opaque in about 5-10 minutes) and proceed with the final cleaning of the tile’s surface using a wet sponge and rinsing it frequently. The total cleaning can be done the next day with a dry cloth. When the grout is still soft, cleaning too early may remove some of the grout from the joints and may cause color variation. It is recommended to apply in small enough areas to grout and clean before the grout dries out too much.

If it is necessary to facilitate the removal of hardened grout, it is advisable to do the cleaning using Tile Cleaner diluted in water (1 part Tile Cleaner and 5 part water).
