I recently stained a basement floor and outside porch for a neighbor. Here is where the problem lies. I used a water based concrete sealer on the porch and basement. It was guaranteed to breathe and not turn WHITE. It turned white on the porch and didn't turn white on the basement. I stripped the sealer on the porch and when I was there stripping freaking sealer for 2 days, my neighbor decides to move furniture in the basement and scratches the sealer which in turn removes some of the stain. I initially applied 2 coats of water based sealer and 2 coats of a sacrificial wax. My question is can I apply a tougher acrylic based sealer over my waxed and sealed floor in her basement? Stripping the basement floor is not an option.
