If you have chosen a cementitious grout, use a grout float to fill the joints. Remove excess grout from the tile surface with a grout float. Clean off the grout with a clean sponge working diagonally across the tiles.
When using an epoxy grout, use an Epoxy Hard Rubber Grout Float to fill the joints. Prior to cleaning off, emulsify the epoxy residue with a damp emulsifying pad and clean off with a damp sponge. To ensure there is no residue, clean again within 24 hours using an emulsifying pad and clean water or mild detergent.
