How to Install Tile Around a Glass Block Window

Installing tiles can give any area of your home a fresh, modern and clean look. Inspect the wall surface that you are planning to tile. If the surface is not smooth or is otherwise damaged, you need to address these issues first. Most of the tiles available for this project range from 4 to 6 square inches. Styles and textures vary. Plan for 1 full day to apply your tile, and 3 or 4 days for the tiles to set completely. Keep the area as dry as possible during this time.

  Determine how many tiles you need to buy. Measure the width and height of the area to be tiled. Divide this number by the size of the tiles. Add 10 percent of this number to your total as extra tiles. The reason for this is twofold: you will need to cut some tiles for the corners or as edge fillers to complete some rows and to replace tiles that are chipped, dropped or improperly measured. You may also need to have replacement tiles if one or two become damaged over time. Tile styles change often and you may be unable to find the same kind of tiles at a later date.

  Clean thoroughly the area to be tiled. Allow the surface to dry completely before you begin. If you will be installing tile near an electrical outlet, turn off the electrical power to the area and remove the outlet cover. You can replace them when you are finished.

  Plan for the installation by "dry fitting" your tiles a row at a time in the designated area to minimize the number of partial tiles that you will need. Cutting a few tiles to improve placement and fit around corners will be unavoidable in most cases, as will be dropping or breaking a few if you are inexperienced.

  Begin tiling around the glass block window, leaving a space of about 1/8 inch between the tile and the glass. You will need to grout the tiles, but caulk the inner corners where the glass block meets your interior walls. Work around the entire perimeter of the glass block window before moving outward with additional tiles.

  Use your trowel to apply the mortar or adhesive to each tile, and press each tile into place along the row, holding for at least 5 seconds to allow it to adhere. Allow for uniform spaces in between and around the tiles for the best look.

  Mix the grout per the label instructions. Apply the grout smoothly in between the tiles. Wait 30 minutes to permit the grout to begin to "set." Use a damp sponge to lightly wipe away any excess grout, especially on the surface of the tiles. Press the grout between the tiles with a thin spatula or wooden craft stick. When the grout dries completely, clean the area with a wet sponge. Wait up to 4 days before sealing the grout with waterproof sealant.
