Porcelain can be a beautiful decorative floor covering but it can be very susceptible to stains since it is very porous. We tried typical water based floor finish, and it just didn't look good. We then opted to try our Diamond Guard TZ Urethane stone protector and ended up with a beautiful look. This customer gave me a sample piece to test out. Even using an SPP pad (by hand) to remove the regular floor finish was causing the colors to flake and powder off. This piece is from Italy and is obviously fragile. Off to the customer to get their opinion on the look. @waxiesanitarysupply @heyitsaaron . . .
