We finally found someone to refinish our kitchen floors - OGDF that look beautiful already - even with the mud slopped all over them. I can't believe we lived with UGLY vinyl floor all these years when this was hiding underneath.

This flooring guy agreed to take on this smallish job for less than his minimum but instead do it by square ft. The only problem is the he wants to use DuraSeal. I have read great things about Waterlox here but not so much about DuraSeal. Can you give me guidance for comparing these two sealers?
