Rain Guard Water Sealers-ConcreteSealer-Penetrating Water Repellent Protection for All Porous Concrete SurfacesWaterBased Silane/Siloxane Sealant Natural Finish-Concentrate Makes 5Gal,Clear Invisible

Very easy to apply and water based for easy cleanup. Sprayed on for fast application.Seals porous concrete very well.

This product is great. Super easy to spray it on and there is no smell to it. Once it had cured after a couple days I tested it and it works perfectly. Even tried oil and it didn't soak in. One bottle did over 1000 sqft but that is because it was power troweled concrete.

i applied the product on new and old concrete outdoors. some in direct sunlight and some on interior concrete and i sprayed it on cinderblocks as a test.i did 2 coats.Water was beading on the areas after the first coat.2nd coat 5 days later water is running off the concrete and im very impressed. would be interesting to see how long it lasts before another coat.impressed with its performance. i believe spraying a penetrating sealer first and then 2 coats of Rain Guard would be the best way to use.for the price its a good purchase and probably could use it in a bathroom or on tiles like slate. 5*

The product seems to be excellent. Amazon guarantees it can deliver but it cannot.My order, taken by Amazon was passed to a third party unbound by Amazon promises.For Amazon I would provide a 0+ rating out of 10. Highly disappointing and disruptive of my project.

It's easy application. But we haven't gotten a heavy rain. I'm hoping it works .
