QUESTIONUsing Polyurethane for a Sealer - I have 30-year-old kitchen counter tile that is in good shape but dulled. Can I put clear polyurethane on it?
ANSWERANSWER - Putting polyurethane coatings over tile is not something that is normally done or recommended. It might work, but I'm not sure how it would last or if it is healthy to prepare food on such a surface.
Glazed Ceramic Tile doesn't normally get dull unless the surface is excessively worn, and then I would not expect it to be uniformly dull. So I'm not sure if you have a glazed or unglazed tile on your counter. An unglazed tile might be sealed and it may have dulled over time and use. If it is an unglazed tile then you could apply a sealer enhancer over it to make it more shiny.
