You've tiled and grouted, but after some months you notice that your wall tiles are allowing for the passage of considerable moisture--right through the stone. Your task, then, is to seal these pesky, porous wall tiles.

Things you need

  • Tile cleaner
  • 2 rags
  • Solvent-resistant gloves
  • Porous stone sealer
  • Tile sponge

  1. 1

    Clean the tiled area. Standard tile cleaner and a wet rag will accomplish this. Make sure that you remove all dirt, dust or filament of any sort from the tiles you will be sealing.

  2. 2

    Dry the tiles. It is absolutely essential that your tiles be completely dry before you apply any sort of sealant. Use a clean, dry rag to dry the tiled area, and allow the tiles to dry from the inside out overnight.

  3. 3

    Put on solvent-resistant gloves. Good stone sealant can irritate or even harm your skin, so wearing gloves for protection is quite necessary.

  4. 4

    Apply porous stone sealer to the tiled area. Use a tile sponge to perform this application. Water-based sealer is probably best, since the wax-based sealers tend to wear down after a while, necessitating frequent resealing. Porous rock sealer is available at any hardware store.

  5. 5

    Wait until the porous rock sealer has dried completely; then apply a second coat. Repeat Steps 4 and 5 until you have applied four or five coats of porous rock sealer. (If you use wax-based sealer, one or two coats should be all you need.)
