Rated 4.7 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by This is the market leader - best you can buy I use this on granite and limestone. A stone mason just told me he uses it on bluestone outside... I've used a lot of other treatments, some imported directly from Italy, and with this one you really notice the difference afterwards. Water beads on top of the stone. Also, one other application: used on solid porcelain recently. Not only did it seal the grout, but the surface was even shinier. Very good product. Best part: low odor, and any odor there is does not last long. June 26, 2012
Rated 5.0 out of 5.0 by A little goes a long way! I used this sealer with a cup and a paint brush. Only one coat was necessary and there was little to no odor. 2000 sq ft of grout was completed and there is a little less than half left in the container. Cleaned up with water and soap. Does not turn the floor glossy or change color of grout. Excellent product and a great value! April 8, 2014
Rated 5.0 out of 5.0 by Excellent penetrating sealant I have used many sealants but this one by far is the best. Easy to apply, absorbes immediately into the surface making it water proof/stain proof as soon as it's dry within minutes. Low fumes, water based...I love this product. Does not change color or add shine. This is a penetrating protectant helps with clean up of leaf stains, wine, etc on natural stone & porus pavers. Excellent product ~ thanking goodness we found it!

Rated 5.0 out of 5.0 by Awesome product This is very easy to put down. I read other reviews, and I went with the foam brush to edge, the foam roller to get up the excess, and the foam sponge to put down the big areas. The sealer took no time to do. April 14, 2015
Rated 5.0 out of 5.0 by DIYers Covered Travertine Lanai and Pool Deck for under $100. After having the area pressure washed, waited for rain free day. Then applied 511 IMPREGNATOR PENETRATING SEALER to deck with long handle paint roller.Even the first coat repelled water. Had enough to do two coats over all. VERY pleased! August 5, 2014
Rated 4.0 out of 5.0 by Great but only indoors I have used this product on interior plaster for more than ten years. Outdoors, though it quickly breaks down under UV. It also has limited ability to protect from oil. A very good sealer, extremely toxic , should be applied with great ventilation while using a respirator and protective clothing. August 29, 2012
Rated 5.0 out of 5.0 by Great Tile Sealer Love how water, milk and other spills bead up on the tile after this sealant has cured. This large container is MUCH cheaper if you need a lot. Highly recommend! July 9, 2013
Rated 5.0 out of 5.0 by An excellent protectant/sealant for masonary surfaces Home Depot gave a great price on the 511 impregnator and the order came quickly. I coated 3 chimneys with a pump up sprayer and was very satisfied. November 15, 2011
