Miracle Sealants 511 Impregnator Advanced Penetrating Sealer for Countertops, Stone, Tile & Grout, Pint

My project: Clean and seal a basement floor after the cats had decided the didn't want to use their litter pan.How much did I need? Approx two quarts for two coats over approx 700 square feet. In other words, 700 sq. ft. per quart.Does it work? Yes, so far. Water beads up beautifully on both the tile and grout that have been treated. It's only been a month so far.How easy was it? Application was easy, but not the cleaning. This is a penetrating sealer, so any stain you leave on the tile or grout will be permanently sealed in. I cleaned the floor by:1. Spot-cleaning the worst spots (cat pee, yuck)2. Scrubbing the entire floor by hand with a stiff brush3. Used a copper wire brush to scrub off the top layer of the dirtiest grout4. Wiped off excess soap5. Mopped twice to ensure no soap residue that might interfere with adherence of the sealantOverkill? Maybe, but I wanted to do this right the first time.For 700 sq. ft., It probably took me 20-ish hours to clean, and only 5-10 to apply two coats. Cleaning was the vast majority of the work.The application process: Easy, but a bit tediousI have 12x12 tiles with approx. 1/4 inch grout. That's about 1,500 linear feet of grout (my best guess). Used a small children's paintbrush and carefully painted over all the grout. After each application, waited 5-8 minutes before wiping off. My tiles are completely matte limestone, and so easily soaked in any excess sealant left on the surface. I just had to buff the excess into the face of the tile, and it would soak in nicely. If I had glass or other glossy tiles, I might have had to wipe off 100% of the excess, which would be much more difficult.The Result: Dry to the touch in hours, started walking on it in a few days.Water beads up fantastically and wiping up is easy. The tiles have a *slightly* but barely noticeable increase in the glossy finish after having dried for a few days. The cats haven't peed on it yet, so I don't know how well it will truly work.Recommendations:1. Ignore the square footage guidelines. What matters is how much *grout* you have, not how much *floor* you have. 2-inch tiles with 1/4 inch grout will need a massive amount of sealant. I had 12-inch tiles so didn't need as much. Make your best estimate and then test before buying what you think might be the right amount.2. Test a small section first to see how much you need. My tiles and grout were very "thirsty" and soaked it all up easily. I put two coats everywhere, and a third coat on the most heavily trafficked section. Test your tiles first.3. Use disposable equipment. Latex exam gloves, a plastic cup, cut-up T-shirts and a child's paintbrush were all the supplies I needed. This stuff needs mineral spirits to clean up, which is a major hassle. Disposable = no cleanup.4. Knee pads! You will be kneeling on a stone floor for hours.Good luck.

This review is for Miracle Sealants 511QT6 511 Impregnator Sealer, Quart, Clear, 32 Fl. Oz.The quart container of sealant was delivered on-time, appropriately packaged and as described by the seller. I need a sealant for indoor and outdoor application to a variety of stone surfaces and I selected this 511 sealant after reading reviews of multiple similar products; the fact that it is made in USA by RUST-OLEUM was also a factor in choosing this product. I will apply this sealant to granite countertops for indoor and outdoor kitchen and for inlaid stone patio tabletops. I performed a test application to a section of outdoor countertop and I am pleased with the result (see before and after photos attached). I cleaned the surface thoroughly before applying and I followed the manufacturer’s directions using a clean, lint-free cloth. The consistency of the sealant is similar to that of water, it was easy to wipe over the surface and I found that a little goes a long way; there is some odor from the solvent so I will be careful to ventilate the area well for indoor application.

This sealer is easy to use and does a great job. We purchased a pint for a 65 sq ft backsplash and a 20 sq ft. shower floor. When I saw the bottle I thought we'd need more for sure, but a little goes a long way! I would say we used a 1/4 cup to seal the 20 sq. ft. shower floor. It was easy to apply, wait and wipe off the excess.I gave it 4 stars as it has a very strong smell. We have pets and kids so we applied it at bedtime when everyone would be in their rooms. Closed all the doors and opened the window in the bathroom overnight. We haven't applied it to the backsplash yet, as that is a bigger job we will have to plan for.As for price - I think it's a fair price for a good quality sealant. A pint might seem small but it will cover a lot. If I bought the next size up it would be a waste of product and money.Updated March 12,2023 - we sealed the kitchen backsplash, 65 square. ft. of dolomite marble and it looks great. It was quick and easy to do ourselves. After both projects there is more than 1/3 of the bottle left. Using the sealer in in big open space we didn’t have the same issue with a strong smell - it was totally fine and didn’t bother us, the kids or our pets at all.

Bought to seal my onyx sink. It was recommended by the seller. This is the second year I have had to seal it and it seems to work fine
