Bests & Worsts Reviews from Amazon

This product works extremely well. I read a few negative reviews that people had written on this product and concluded that they did not read and/or follow the manufacture's directions. The reason I say this is that when my granite countertops were first installed, the installers only wiped this sealer over the surface then left. I too, had areas that would darken when water would hit the stone, and I wondered why. However, when I applied the sealer liberally (2 yrs later, for the first time since the countertops were installed), allow the sealer to penetrate the surface for 15-30mins (as recommended), wiped off the excess after 30min (which there was minimal, the stone absorbed most of the sealer), and did not use the surface for 24hrs (as recommended. By the way, I took advantage of sealing the surface before I went away for the weekend so that there was no impact to family life.) I had a nicely sealed surface. I no longer have areas that darken when water stands on the stone. I would recommend this product to everyone.
