My remodel is almost finished and builder suggests that we seal the wall ASAP. He says he can do it (not sure what he will charge extra for this) or I can do it. I am looking at my options and depending on cost I may do this myself. I however, don't have any idea what is good product/cost wise. Can someone point in a good direction? I looked at the Dupont Stonetech stuff and a couple other products I can't remember at the moment. It all seems pretty expensive, especially the Dupont stuff. Some advice would be appreciated. We are looking for a sealer/enhancer product.
