How can I add a clear glaze to my floor tile that has a rough finish( no glaze). I would like to add some shine and darken the color slightly with a clear product. What should I use.
Yes, I apologize. This belongs to a friend I am tryig to help her. It looks like a slate without a seal/glaze. Unfinished/raw 12" tile in a terracotta coler. We need to darken the color and add a little sheen and that is why we are asking about a glaze. I am not sure a sealer will do that - or am I mistaken. Thank you for your help.
