Doing a good job when you grout slate flooring is important so that you end up with a neat and level floor. There are a few important key features to keep in mind when you are doing this type of work, see the instructions below for more information.

Step 1 - Cleaning

Once you have laid the slate tiles over the mortar, it is important to clean off any excess dirt or debris. Use a vacuum with a hose attachment to pick up dust and other residue from the lines around the tiles' border.

Step 2 - Applying Tile Sealant

Next, apply a coating of tile sealant onto the tiles. Use a paintbrush and try to apply it smoothly over the surface of the tiles. Stay away from the tiles' edges. Allow it to dry and then apply a second coating. Make sure you allow the sealant sufficient time to dry well before proceeding. The sealant will help a great deal to avoid having the grout settling and sticking onto the tiles' surface.

Step 3 - Grouting

Use a grout squeegee to fill the lines between the tiles carefully. Use a small amount of unsanded grout every time. Press the grout squeegee down to fill in the space well. If you need to clean off any excess grout, use a damp sponge and clean it quickly.
