Applying The Floor Tile Grout
Floor Grout Application
Before beginning, clean joints and surface of tile thoroughly to remove dirt and dried thinset mortar. Fill all perimeter tile joints (e.g., along walls, around cabinets, etc.) with a siliconized mildew resistant caulk. Mix grout mortar thoroughly, removing lumps, to the consistency of peanut butter. Place a generous glob of grout on your starting point. Then hold the grout float at a slight angle and squeegee the grout mortar into the tile joints. Grout only a small area of floor at a time until you begin to feel comfortable with the process. Use a clean grout float to remove any excess grout from floor. Allow up to 15 minutes for the grout to set and then proceed to wipe floor clean.
Use a margin trowel to remove excess grout mortar from corners and along baseboards. Remember to grout under the base of your toilet.
Keep a clean bucket of water available and replace as necessary. Take a damp sponge and place flush on tile at an angle to tile joints. Pull sponge down and towards you. Be careful not to dig the grout mortar out of the joints.
Flip sponge over and repeat making sure to overlap the adjacent area you have just wiped. Then rinse sponge thoroughly and repeat process. Some areas may need to be wiped more than once.
This floor is finished. Allow 24 hours for grout mortar to set before walking on tile. Use 1 cup of white vinegar per gallon of water and mop floor thoroughly to remove leftover dust or grout haze from tile. Rinse with clean water. Lightly mist grout joints one time daily with clean water for the next three days.
