It is important to seal limestone tile since the structure of limestone, which is calcite, is highly reactive to acids. Applying sealer creates an impregnating barrier on the stone. Here are the materials and steps for how to easily seal limestone tile.
- Impregnating sealer specific to limestone
- Foam paintbrush
- Lint-free cloth
- Stone cleaner
- Small bowl
Step 1 – Clean the Limestone Tile
Clean the limestone tile with a stone cleaner, to remove any debris that has stuck on the surface of the tile. Use a lint-free cloth to spread the stone cleaner evenly on the surface. Let it dry.
Step 2 – Impregnating Sealer Application
Pour the impregnating sealer into a bowl, and immerse a portion of the foam paintbrush on the sealer.
Step 3 – Spread the Sealer
Spread the sealer evenly on the tile surface, using broad strokes, until the entire surface has been covered.
Step 4 – Dry the Sealer
Leave the sealer to dry for 30 minutes, before wiping the surface of the tile with a clean cloth.
Step 5 – Buff the Tile
Using the same cloth, buff the tiles in a circular manner, until everything is dry.
Step 6 – Sealer Second Coating
Apply a second coat, 2 hours after the application of the first coat, for added protection.
