- 1). Wash the tiles well, particularly if they have been installed for a while. Remove any dirt, debris, grease or other substances that can interfere with the ability of the sealer to penetrate the tile's surface. Allow the tiles to dry completely.
- 2). Pour the sealer out into a paint tray or wide-mouthed dish large enough to dip the roller or brush into. Dip the roller or brush into the sealant and allow it to absorb as much as possible; the brush or roller should be fully saturated when you apply it to the tiles.
- 3). Brush or roll the sealer across the surface of the tiles. Glazed tiles will not absorb the sealer the same way that porous tiles will, and the sealer will spread over the surface. This is fine; the sealer will be absorbed where it is needed and the rest will wipe away.
- 4). Brush or roll the sealer from the top or back of the tile installation forward and down to prevent drips. The sealer will go on and appear wet; check for dry spots to ensure even coverage. Allow the sealer to sit on the tiles for approximately 10 minutes.
- 5). Wipe the excess sealer off the tiles with an absorbent cloth. Buff the tiles completely dry to ensure no sticky residue or buildup remains on the glaze.
