511 Impregnator Advanced Penetrating Sealer for Countertops, Stone, Tile & Grout, Gallon

Thrilled with this grout sealant. I applied it to shower grout that was taking forever to dry (I allowed it to dry first, of course). The grout is a medium gray, so I tested this first to see if it'd darken the grout permanently - it didn't. I applied 2 coats as directed on the grout, wiping away excess after 3-5 minutes. 72 hours later I used hot water and 7th generation disinfectent with magic erasor pads to remove the film - a trick I learned some time ago in getting rid of grout film as well. It's working well, and the grout dried to it's original color.

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.

I’ve been using Miracle Sealants 511 for a while now, and overall it’s a very solid product. It goes on easily, absorbs well into stone and tile, and provides noticeable protection against water and everyday stains. After application, the surface looks natural not overly glossy or darkened which is a big plus. The sealant definitely does what it promises, but the price is a bit on the higher side, and proper ventilation is important because of the strong smell during application. With that in mind, the performance and durability still make it worth it. I’d recommend Miracle 511 to anyone looking for reliable, professional grade protection, just be prepared to follow the instructions carefully for best results.

This product works very well. As you would expect there is a strong smell so wear a mask and/or vent the area well. The first coat penetration was good. The second coat took less material and did not penetrate deeply. This showed that the first coat was working properly. After drying for 36 hours I tested it with water. The water beaded well. Product said it is good for 20 years but will regularly cleaning of our shower I found it better to reapply after a year.

I would not have thought that even tile needed to be sealed. After installing our tile floors, we sealed and prepared them for everyday use. This was an easy product to use, did not require any extra tools and was quick to apply. Keep you floors looking as beautiful as the first time you put it down. This is a good product. I would recommend it!

I took a chance that all the good reviews were accurate and purchased a pint of the sealer to try. I have to say, that at least in my case, it works as claimed. Although the odor is not too bad, one should use as much ventilation as possible while applying it. However, once you wipe the excess off after the five minute soak in period, the smell is negligible. I applied two coats and the water now beads up rather than soaking into the tile and grout. I would definitely recommend it.

This sealant works well for waterproof but the smells is hard to dismiss which was taken one week to getting better.

Easy to use and worked as advertised
