Rated 4.0 out of 5.0 by Sealer I was told to get the $90 bottle of 511 but decided on this at $10 per can. This was my first time sealing grout. I found that the spray came out too much and left a lot on the surrounding tile so I spray the longest lines and then got on my hands and knees with an old tee-shirt to work the excess sealer into the horizontal lines running through the long vertical which worked like a charm, no waste. The tile was porcelin and cleaned up well. Very slippery if you walk on it before wiping off so be careful. The T-shirt ended up very damp which allowed me to use it for a second coat. So I got more out of it then planned. I used 2 cans on about 400sq ft. After a 2 hour wait I did the water test and the grout repelled it as promised. Hard work but it was worth it. USE GLOVES and VENT area well! April 26, 2010

Rated 5.0 out of 5.0 by Awesome Product! No More Leaks! I had an old tile shower that was leaking into the room below. I caulked everywhere. It still leaked. The 511 spray was easy to use and solved the problem completely. January 27, 2015
Rated 5.0 out of 5.0 by 511 Grout Sealer I drove 47 miles to buy this product because another LARGE home improvement store near me had terrible reviews for their spray on grout sealers. This 511 product is simply amazing. It is so easy to use and , for the the obligatory water test, it passes with flying colors ! It was so easy that I did it twice, not that it needed it, but because it was fun. Just be sure to provide all of the ventilation you can, and if you have appliance with standing pilot lights, I would suggest extinguishing them. I would recommend this product to anyone !!

Rated 4.0 out of 5.0 by PRETTY SIMPLE TO USE Although the Miracle Sealant is easy to use, it does spray all over the place. It would be a lot easier if they used a nozzle that concentrates on actually spraying the grout lines, rather than the whole tile. A lot gets wasted & one can will actually cover an 11'x11' room. You do need to leave the house for few hours as the chemical smell is pretty intense. Overall, the product does a good job. September 6, 2011
Rated 4.0 out of 5.0 by It dries in 2 hrs as stated with windows open in 60s temp. I used the sealant for kitchen floor grout. I wish there is a spray pipe to direct sealant onto grout so there is less waste onto the tiles. It needs 2nd spray and protects it like new. It takes lots of time thoroughly cleaning floor, covering baseboard and cabinets before sealing. It should be easier when the floor is new. Previous owner left us a greasy floor. March 22, 2012
Rated 4.0 out of 5.0 by WORKS FOR ME! I read reviews of other products before going into the store and purchasing this, and I'm glad I did. The thought of getting-down on my hands and knees with an applicator tracing each and every grout line made me cringe. Spray-on sealers are more convenient and just makes so much sense! I agree with the other reviewers, the product emits fumes, therefore I'd suggest planning to apply the sealing right before you leave the house. It will take a few hours before the air is 'clear' again. And definitely crack a window or two. I gave the product a '4' rating because of the size of the sprayer - ALOT of product comes out when you spray it, thus making it messier than it has to be, and requires alot wiping. However, although alot of product does get onto the tiles, it doesn't leave a residue or haze behind at all. April 25, 2011
