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

I recently used Miracle Sealants 511 Impregnator on my tile project, and overall, I’m really pleased with the results. The application was straightforward and easy; I just brushed it on, let it sit, and wiped off the excess with no issues. There was hardly any odor, and cleanup was quick. Most importantly, it actually works as described. Water beads right up on the surface, and I’ve noticed that dirt and stains don’t stick to my grout like they used to. It gives me peace of mind knowing my floors are protected. The only thing I noticed was a slight change in the color of my grout. It went from a true tan to more of a yellowish tan after sealing. It’s not dramatic, but if you have lighter grout, it’s something to keep in mind. Still, I’d recommend this product for anyone looking for an effective and easy-to-use sealer.

Great! Did the job!

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.

Used Miracle Sealants 511 Impregnator on a new bathroom renovation. Applied on both grout and ceramic tiles with a paint edging applicator. Worked great. Followed the instructions and wiped everything down after the 3-5 minute wait window. It is a clear product so there is no tint to worry about. Water bead up and is easily wisked away with a squeegee. Would recommend the product to anyone.

The 511 Impregnator Sealer from this seller is an excellent value when compared to local stores who sell the same product. My intended application for the sealer is to seal limestone (white) blocks for prevention of moisture absorption. The blocks (exterior yard application) look great when first set but are quick to absorb moisture, and over time black mold appears which cannot be removed. Consequently, the beauty of the garden is quickly tarnished once this occurs. I called the manufacturer of the 511 sealer and explained that my intended purpose is to apply the sealer to exterior limestone blocks to prevent moisture absorbtion in an outdoor setting. They said it would achieve my purpose and suggested using at least two coats of the sealer. I first brushed the blocks with a stiff bristle brush to remove surface dust and then applied the sealer liberally to the limestone blocks. I allowed several hours between coat application on a 80 degree day. The optimal method for applying the sealer is with a 3 inch cheap paint brush dipping sealer out of a one quart plastic paint container. The sealer goes on effortlessly. I coated the top and one exterior side. I coated 60 linear feet x 8" height of limestone blocks using the one gallon product. I had over a quart of sealer left upon completion. I had a concern that the blocks would yellow or darken after the application. However, I was pleased that the original white was maintained after the sealer dried. I will follow-up on this 12/17/21 review in May / June 2022 for the purpose of how effective the product was for maintaining the original appearance of the limestone. May 2024 I am following up on a review done in 2021 concerning the performance of the 511 Impregator sealer. I applied this great sealer to limestone blocks some three years ago and amazingly no fungus, mold or other has grown on the limestone blocks placed in my wife's garden. They have retained their nice white appearance over the years. I highly recommend this sealer.

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.

I bought whole gallon and treated/prepared for rainy seasons my outdoor porch terracotta tiles. I lost count how many times I applied with sponge. Many times as I had a whole gallon. After first rain, tiles appear to be soaked/discolored, so looks like it is not working. This is deeply penetrating sealant and highly recommended by customers, so I am confused how it works for some and doesn’t for others. Perhaps that is not the best product for terracotta tiles?!

Quality product
