I am putting down 1/2 inch plywood as my kitchen counter... I k ow it's not a good solution.... but the kitchen needs major work, and I cant right now. So..... the question is this. I have put peel and stick flooring tiles on the first counter, how can I seal the edges? Can I just paint the edges? Will that seal them well enough? I am going to take the main counter top off, cut a hole for the sink, put flooring tiles down and have a different sink installed (mine is fiberglass and I have had had to spray rubber sealant on the bottom several times.) Heres a pic of the cabinets I moved to make some workspace, flooring tiles already attatched to that one.
