Easily Seal Limestone Tile

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.

Materials Needed:

  • 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.
