expensive
considering a lot of coats need to be applied to offer real protection. Ended up using it as a base sealer on the grout for the ceramic tile in the shower with acrylic sealant over top to finish the tile and grout. Ok on prepolished granite which needs to be touched up, did not hide deep scratches. Not sure enough coats would even cover/protect a clearly visible scratch, or any of the rough pits and uncoated, abrasive imperfections.
