511 Impregnator Penetrating Stone & Tile Sealer, Pint | Penetrating sealer for no-sheen stain, water & oil protection for granite, stone, tile, masonry & grout. Dries invisible.

We did a lot of research before trying this. To sum it up this will darken the grout. It doesn't change the color much but it does change it a little bit. In our case it made it look nicer. More coats will darken it even more. Although you probably don't need more than about 1-2 coats. Since it doesn't repel water it actually will allow the grout to change color when it is wet but then the water will quickly dry. When without the sealer the grout will change color when wet and stay wet a lot longer. It doesn't change the look of the tile. Use an applicator that is designed for this. A little bottle can do a LOT of flooring. I didn't even wait 12 hours and was walking all over it. It didn't hurt it but I have heard that it can be a problem. For me it wasn't. If you have to walk on it don't use shoes. Just wear socks. It should be fine. It is dry to the touch in less than an hour. The fumes were not really that bad but I had opened all of my windows and had fans running. It is the worst when it is drying. Once it is dry it doesn't smell. Obviously this is not something you want to get in your eyes or mouth. It is very runny like water and does go a long way. All you do is put it down with the applicator and wait about 5 or so minutes. Don't let it dry. Wipe if off with some towels. It doesn't hurt the towel but I washed them by themselves in the laundry just to be sure. Came out clean. Used hot water. Overall it's a pretty simple process once you know what this stuff will do. Do not expect it to repel water. That simply isn't what this does. It hardens the grout so that nothing can be absorbed into the grout but it does not form a coating over the grout. So it does not appear waterproof and is not waterproofing the floor. Only preventing stains from happening.

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 brush 3. Used a copper wire brush to scrub off the top layer of the dirtiest grout 4. Wiped off excess soap 5. Mopped twice to ensure no soap residue that might interfere with adherence of the sealant Overkill? 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 tedious I 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.

The sealer itself is great. It applied quickly and easily with a pump sprayer and absorbed into my bluestone without any need to wipe or roll out excess. It did not leave a haze on the stone, as the instructions warned might happen. We've had a couple of rains since and it seems to repel the water well. My only comment, and it's an important one, is that the coverage is about 20% of that advertised. The quart-sized bottle is supposed to cover up to 1000 sq. ft. In fact, it covered only about 200 sq ft, even when I was careful to apply it lightly.

The product works so far and my shower floor does not leak, of course, I first applied epoxy to the cracks in the floor as I was instructed by Gemini. All is well so far and I believe I am very happy with the results.

I recently purchased a home that had the bathroom and kitchen remodeled prior to my ownership. The previous owner did not leave any information about the upkeep of the bathroom tiles or the care for the kitchen counter. Then I found out the hard way that my shower tiles (and grout) need to be sealed occasionally. My shower water was leaking through the grout on the walls into my basement. Yikes! The 511 Impregnator Sealer was a real-life saver. Since I am a shower person, I had to clean (and dry) the tiles before sealing them. BEWARE: the sealant has a very strong odor. Be sure to wear a mask, gloves and safety goggles when applying. I used the bathroom fan and opened the window, closed the bathroom door and the smell still permeated the house. Aside from the smell, the 511 Impregnator Sealer worked wonders. My tiles look new again. It did not change the color but added a great shine and glow to them. Be sure to put an ample amount on the grout between the tiles as this is where most of the water leaks takes place. I bought an applicator, but the instructions suggest you can also use an old rag, which you will need to throw away when done. The smell lingers and is very pungent. I plan to seal my bathroom floor, as it's the same type of tile and grout. Along with my kitchen floor. The sealer is a great idea for the kitchen floor and counters since you don't want food or drink stains on either. I do not know how food friendly the sealer is, but I always use cutting boards for everything on my kitchen counter. I do not know how often this application will be needed in the shower, but time will tell, and I plan to keep 511 Impregnator Sealer on hand for the next application. Despite the strong odor I will use this product again.

So, I got this in mail for some reason rather than a normal Amazon delivery. The product had leaked - about 1/3 of the bottle was empty and the box was reeked of evaporated product. The leak happened at the cap. I jumped through a bunch of hoops in the Amazon return process and got a full refund without having to return the 2/3 full messy bottle. But, since I had 2/3 bottle, I proceeded to use it on my counter. It seems to have done a really nice job. Hard to really tell since I just applied it, but it seems good. It does smell like paint thinner or something, but based on the product warnings I was expecting much worse. I opened some windows and it was fine.

Been using Miracle Sealant 511 for 10yrs.Had new granite countertops installed, and the installer recommended this product to keep it looking good. Been very happy with the results .

This is very good sealer. I bought another on with a brush on it and use this to refill....

My granite kitchen countertops were absorbing liquids and becoming stained sometimes. They have become 100% waterproof after using this product.

Very good product.Got this to seal my slate floor.Easy to apply very natural finish and stops the slate flaking.In the bath area applied on the granite floor it works as a sealant and gives a subtle roughness to the surface making it less slippery.

Good

Honest review. Our bathroom fitter didn't seal our grout lines. Water was absorbing into the grout and leaking down back of bath. Bought some grout sealer from Topps tiles and applied 4 coats but water was still absorbing in. Searched for best grout sealers and came across this. Bit wary as it has a cancer and reproductive warning on the label and on Amazon description. I opened the windows and wore a face mask and latex gloves. Tipped some product out into an old double cream plastic pot and applied on the grout lines with a paintbrush. Left for 10 minutes and wiped off excess with kitchen towel. Reapplied another coat after 4 hours and left to dry for 36 hours. Used shower and the results were amazing. You can see the water beading up and running over and down the grout lines and tile faces. Absolutely amazing product. I would definitely recommend to anyone who wishes to seal their grout. Dearer than all the other ones but obviously you get what you pay for. The bottle will last a lifetime!!! No more leaks!!! Yay!!!

Wow, I followed the instructions and applied a coat of this sealer to a brand new marble chopping/pastry board, I let it completely dry and then added a second coat. After it had dried again, I poured a little water onto the marble, it was sealed completely. Marble is very porous and without sealing will absorb most liquids and leave behind an unwanted stain, now I am confident as can be that any spillages will just sit on top and wipe away with ease. I am more than happy to fully recommend this sealer to anyone that needs to seal pretty much anything.
