Customer had new sandstone floor sealed with Cementone Natural Floor Sealer by her builders. The seal has not worked as the stone is still porous and has marked and soiled very easily.Have tried a small test patch using STS but to no avail. Was thinking of trying wax/res next but would a honing powder assist in cutting through the seal to get back to the stone so that I can re-seal.Any thoughts?
KevThanks for thatWhat grit honing powder?
