Gran quartz has solvent based glossy sealer with an enhancer. I use this sealer often on the slate and so far I had no complains that it wear off.

Subject: [sccpartners] topcoat over impregnating sealer?

Have a situation where a homeowner removed urethane from a slate indoor sunroom floor, impregnated it with solvent based color-enhancer and now wants a glossy topcoat. The background is that he removed the urethane himself, had a floor expert come in to strip and clean and then apply the color enhancer, which is what they recommended (and makes sense to me).  But, he says they didn't really explain what the results would look like and he thought the floor would be glossy.  I told him that applying a gloss topcoat to slate is iffy anyway depending upon wetness issues (he never had a problem with this before), but now a new topcoat may not adhere properly with the color enhancer in the stone. I haven't really had to deal with this before.  Is it possible to  strip or partially strip the floor of the color enhancer and apply a gloss finish like a polymer or similar? Perhaps a mexiglaze if it will work with the solvent?
