FILA Natural Stone Sealer, MP90 ECO Xtreme, Natural Look Sealer and Stain Protector, Ideal for All Natural Stone, Polished Porcelain Tile and Grout, Eco-Friendly Water Based, 1 QT

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.

I've been using Fila products for the last 15 years or longer and can't find another penetrating sealer that comes close to comparing with the MP90. All of their products are excellent. Another favorite is their neutral cleaners.

We have matte porcelain dark plank wood tiles with grooves in them. We wanted this product to help make the cleaning of our tile easier and also enhance the look. Nope ! Did not work, but left a hazy film on the tile and the tile looks terrible after being washed. Very disappointed since we believed it could be applied to matte porcelain tiles. Now we have to spend the time getting it off.

Great sealer. Doesn’t change stone color. Easy to apply

Difficult to put on evenly
