I'm trying to find the best way to apply protection on this quarry tile I'll be messing with in a few weeks. I know that an impregnator, like Harvard's Stone Impregnator 407 is probably the best because of how it seeps in the grout and quarry. But it'll dry invisible and I think my customer wants a gloss look to it after I'm done. So I'm considering applying something like Harvard's Marbleous Sealer/Finish after I put down the S/I 407. My question is: Will the Marbleous stick to the 407 correctly? Any of the Harvard guys on here to answer this?
