To put grout on tile, the actual process involves sliding it out using a grout float.
Here's a breakdown of the typical process for applying grout:
Preparing for Grouting
Before you start applying grout, ensure your tile surface is clean, dry, and free of any debris or adhesive. This step is crucial for a strong and even grout application.
Applying the Grout
Once the grout mixture is prepared according to the product instructions (it should have a peanut butter-like consistency), you're ready to apply it to the tile joints.
Here's the key technique:
- Scoop a manageable amount of grout onto your grout float.
- Holding the grout float at a roughly 45-degree angle to the tile surface, spread the grout across the tiles.
- Slide the float back and forth and diagonally over the tile joints to push the grout down into the gaps and ensure they are completely filled.
- Use the float to scrape off excess grout from the tile surface, pulling the float across the tile at a steeper angle (closer to 90 degrees) while making sure not to pull the grout out of the joints.
Key Tool: The Grout Float
The grout float is specifically designed for this task. It's typically a rectangular tool with a rubber or foam pad attached to a handle. The flexible edge allows you to spread the grout smoothly and press it effectively into the joints.
Technique Tips
- Work in small sections to prevent the grout from drying out too quickly.
- Ensure all joints are packed solid with grout, checking for air pockets.
- Scrape off as much excess grout from the tile surface as possible to make the cleaning process easier.
Cleaning Up
After applying the grout and allowing it to set for the recommended time (check product instructions), you'll need to clean the tile surface to remove the haze. This is typically done with a damp sponge, wiping diagonally across the tiles.
Following these steps, particularly using the grout float at the correct angle, helps achieve well-filled and smooth grout lines.
