How to Restore Ceramic Tile in a Shower
- 1). Clean the tile with household tile cleanser and a brush, getting it as clean as possible.
- 2). Use your drill and grout remove bit to grind out the existing grout between the tiles. Use the bit holding the drill sideways next the wall and pressing the thin edge of the bit into the grout line, then slowly moving it forward along the surface.
- 3). Remove the debris from the grout lines with a vacuum hose.
- 4). Spread grout over wall, starting at the top and working your way down, using a grout float. Scrape the long edge of the float along the surface of the tile, forcing it into the lines between them while squeezing it off the surface.
- 5). Let the grout sit in the lines for 10 to 15 minutes. Wipe off the excess grout with a damp sponge.
- 6). Allow the grout to set for two or three days. Then apply a thin coat of sealant over the grout, using the applicator bottle it came in. Let the sealant set for a day before using the shower.
