Natural stone tiles like granite, marble and slate are attractive alternatives to ceramic tiles. They are known for providing exquisite, unique colors and textures. They are often integrated in shower walls, entryways, and countertops. Just like other types of tile, the space between natural stone should be filled with grout. However, you must take extra steps to protect stone when you are grouting it. This is because the sanding in the grout can scratch the stones.
You also run the risk of having the grout get into the pores of the stone ruining its appearance.
To keep this from happening, you must seal the surface of the stone before proceeding with the grout. This article will tell you the steps you need to take when grouting natural stone, so you end up with a terrific, finished product.
- Use a natural stone sealer and sponge to seal the entire surface of the stone. Follow the manufacturer’s directions and allow the sealant to cure before proceeding. Be careful not to get the sealant into the grout joints as this can keep it from bonding.
- Pour the grout into a bucket and add water as per the manufacturer’s directions. Use a margin trowel to mix the grout until it has a creamy consistency. Wait 10 minutes and mix again without adding extra water.
- You can use the trowel to apply the grout to the joints between the tiles but using a grout bag and squeezing the grout into the joints may be the way to go. This will keep the grout from smearing onto the stone tiles.
- Hold the grout float at a 45-degree angle and sweep it across grout lines horizontally. This will ensure the grout provides even and complete coverage. Use the grout float or margin trowel to wipe the excess grout from the tile surface.
- Wait 30 minutes, then use a damp sponge to wipe excess grout from the joints. Wring out the sponge after each swipe using clean water from another bucket.
- Run the sponge along the grout lines using a light pressure from your forefinger to ensure the grout lines are of uniform height and do not show any smears or lumps.
- Wait several hours. Then wipe the tile surface down using a dry rag to remove the dried haze.
- Wait 24 hours and apply a grout sealer to protect the grout from mold and damage.
