So basically we are trying to find some cheaper ways to install new countertops in our kitchen. We both really like the tile look similar to below. Also seems easy enough that I could do it. What we really dislike it the ability for the grout to get dirty and being hard to clean over time. Sooo...my question is, am I able to build my countertops like the picture, and then apply a clear sealant or glaze over everything so that I don't have the rough grout edges. Something like a clear epoxy that I can smooth out, be completely clear, and not be able to damage too easily. Also, would it be better to just glaze over the grout areas, or would I go over the tiles as well. I've done simple tile installs before, but I'm just not familiar with how this might work. Thanks in advance for any help and suggestions guys.
