Natural Stone Sealer MP90 Eco Plus 1 QT, Natural Look Sealer and Stain Protector, ideal for All Natural Stone, Polished Porcelain Tile and Grout, Eco-friendly Water Based

I have used the previous versions (which were great) and this one was even non-toxic, which was nice to know for the kitchen use. I had a fairly large granite countertop and island and it absorbed a fair amount of product. Do make sure to not let it try before wiping with a clean microfiber cloth, if it does you will need to rewet and scrub quite hard to ameliorate it and make it shine. Now water beads nicely on the surface and the counter is even more shiny. I am pleased with the protection it provides.

No, I'm not kidding. BEST!!! I've used a few different grout sealers over the years, and those before using this product had such strong fumes it was difficult to even stay in the bathroom while applying them. And they took 24 - 48 hours to cure before you could get the surface wet. This product is everything the others sealers want to be. Easy as heck to apply, almost no fumes, doesn't change the color of the grout, and the prepared surface is ready to use after 8 hours. I did a shower floor sized at 32” x 51” of penny tile. So, *lots* of grout. The sides were more of a subway tile layout with minimal grout in comparison. The thin sealer seeps into the grout quickly, which is good since that allows it to seal even the smallest pores. I also expected with such a large area of grout to seal, I'd need the full quart bottle rather than the half quart. I didn't use even quite half. But that's okay, that means I can let what I applied set for a week or so, then apply the sealant again, just because I can.

Good quality and goes a long way.

Got this based on recommendation from our stone repair guy - we put in a cast stone hearth and were told they don’t seal the product / it doesn’t work. During a small repair from the man i call the stone whisperer, I mentioned this and he said they were wrong and this would work great to protect from every day accidents / water rings / etc. Super easy to apply - just follow the directions on the bottle. Left the cast stone looking just as it did before, but testing shows it causes liquids to ball up and be removed easily!

Brings back the vibrant color in stone!
