What Type of Grout Sealer should You Use for Glass Tile? What Type of Grout Sealer should You Use for Glass Tile?

To protect your glass tile from water, acid and oil-based contaminants, you can use grout sealers. Membrane-forming and penetrating grout sealers are the two most common types with the latter ideal for glass tile sealing.

Penetrating Sealers

Penetrating sealers are perfect for sealing glass tiles. These sealers have soaking properties that are absorbed deeply into the tiles. When the base liquid evaporates, deposits are left in between voids. These deposits resist grease, dirt and liquid spills that accumulate in the grout’s edges.

On the other hand, membrane forming sealers are made to change your grout’s color. Instead of soaking into the tile, they harden into a glossy finish.

Applying the Sealer

Spread the sealer into the entire surface using a soft paintbrush. Allow the sealer to soak into the grout for 2 minutes. Wipe off excess sealer with a paper towel. Do not forget to wipe off excess sealer after a few minutes of application. You may find it difficult to remove sealer residue that has dried off after an hour.

For outdoor glass tiles, apply two coats of the sealer while one coat will do for indoor tiles.
