Peeling Sealant on Black Granite Floor Tile
by Thomas Sammons
QUESTION:What should I use to remove peeling sealant from black granite floor tile? I had som painters doing work, and when they were cleaning spilled paint from the floor, the sealant on my floor tile started to peel.ANSWER:You may have some type of "sealant" or coating on your tile, but a standard granite sealer is an impregnating sealer that absorbs into the granite pores below the surface.So, it does not peel off. Now this could be some complication related to a granite sealer applied to the floor... since this is black granite chances are that it is too dense to even absorb a sealer and never needed it in the first place. Often when a sealer is applied to black granite it just dries on top, but this usually leaves a very noticeable haze on the surface. And paint should not strip anything... paint thinner, paint remover.... yes. I'd suggest two things: 1. Use methylene chloride (a paint stripper) to clean off whatever is on the surface of your granite floor. Now this stuff is noxious, crummy to use and you'll need to adequately protect everything (cabinets, floor boards, etc.) and provide excellent ventilation. Won't harm the granite, but will definitely remove a granite sealer if that's what it is. Or... 2. You can use DEEP CLEAN Stipper/Degreaser for stone. Much easier to use and may do the job just fine, but not nearly as potent as methylene chloride and won't remove a true granite sealer. Given that something is peeling off after exposure to paint (not a potent chemical), I'd say give the DEEP CLEAN a try first. Good Luck, Ryan P.S.
