Tile Glaze Repair

The glaze on your ceramic tiles is a baked-on sealant that gives them that trademark shine. When the shine starts to get dull and dingy, re-baking the glaze on them isn't an option, but there are other ways to restore the surface. Polyurethane gloss, generally used on wood flooring, will mimic the look of the original glaze. You have to dull the tile surface to get the gloss the stick properly.

Things You'll Need

  • Belt sander
  • Medium-fine sanding belt

Instructions

    • 1

      De-gloss the tile surfaces one by one with your belt sander and medium-fine sanding belt. Don't attempt to sand off the finish (you won't be able to), but just dull the shine. Clean off the dust with a dry rag.

    • 2

      Brush polyurethane gloss over each tile with a finishing paint brush, using a thin, even stroke in a consistent direction. Don't gloss the grout lines, just the tile surface.

    • 3

      Allow the polyurethane gloss to set for 12 to 24 hours.

    • 4

      Use your extra-fine sandpaper to dull the surface of the polyurethane gloss with quick, light strokes. Wipe up the dust thoroughly.

    • 5

      Apply a second layer of polyurethane. Let it dry, buff it with extra-fine sandpaper, and apply a third coat.

    • 6

      Let the third coat set for 24 hours.
