One of the first projects I did was a table for the little kids with
tile set in the top. I used the normal tile mastic to attach it to
some plywood, then used normal tile grout. Years later, it looks
pretty bad, especially the grout. My wife has requested a new kitchen
table with a tile top. But I'm worried about the grout. She requested
something like bar top over the tile but I think this would look wrong.
So I'm looking for alternatives.

What about epoxy instead of mastic and grout? It would sure make the
tiles stick. And I could make the epoxy whatever color I wanted. I'm
thinking I could make a form with glass or something in the bottom of
it, then position the tiles face down, then pour the epoxy over the
backs of the tiles. The epoxy would fill in the "grout" lines, maybe
helping out the bubbles with a heat gun. If the tiles have a curved
edge to them, I might have to sand them square, cut off the curves, or
find tiles with sharp corners.. Can anyone see a problem with this?

Or maybe there's a sealant I can put on the grout after grouting that
would make it easy to clean? I'm thinking the normal rough texture of
grout would be difficult to keep clean.

Any other ideas?
