I have split brick flooring on a slab in my kitchen-it has some kind of urathane sealer over the top. I had my washer overflow and water got in between the brick and the sealer and now there is a milky look to the floor. I assume the water has made the sealer separate from the brick causing an air space between the brick and the sealer. It has not started to chip off or flake. what is the best fix? 1)remove sealer and then reseal? How would one go about doing that? Would it be just as good to take sealer off and leave it off? Is it cheaper to just replace whole floor?
