  • Easy to use, clearly effective
Size: 2.5 Gallon
I sprayed this on a concrete block knee wall for a greenhouse. Was really easy to apply with a sprayer. Total job took about 30 minutes, which includes waiting for the first coat to dry. I could see the water beading off of the concrete the first time it rained after the application. I'm assuming I'll have to do this every few year but it was so easy and inexpensive, I'm happy to do that! ... show more

  • Works as advertised.
Size: 1 Gallon
Water sheds right off of the brick. Good price, no discoloration.

  • Seems to work well
Size: 1 Gallon
One of those things that’s hard to know what’s in it, how long it will last, or how it will perform against other products. Not like paint you can see and touch. Kind of like flossing your teeth, you just do it because you’re supposed to. Went on easy, seemed to penetrate well, and surfaces beads water like crazy, at least in the short term. ... show more

  • WEAR EYE PROTECTION!!!
Size: 1 Gallon
Stuff was real easy to apply!!! I used a cheap sprayer but it got the job done. Oh' and make sure you wear eye protection and maybe a hoodie!!!! This stuff goes flying all over the place and sadly that includes eyes!!! But on the bright side, I think my eyeballs will be waterproof for the next 6 months.... ... show more

  • Sealer on Blue Stone patio
Size: 2.5 Gallon
This sealer rolled on easy and smoothly. I like how “liquid” it was compared to other sealer. Rolls on with smooth roller.

  • Not sure
Size: 1 Gallon
Hard to tell if product worked. Obviously I have a bigger leak issue than I thought.

  • Works well on my stone patio
Size: 2.5 Gallon
I used 3 each 2 1/2 containers for application on my new rock patio and stone wall. I used my garden chemical sprayer and followed directions. It sealed the rock and stone extremely well. The best part so far was how easy it was to clean this spring, no electric spray washer just a powerful sprayer on my hose. Was done cleaning in a fourth of the time ... show more

  • Keeps concrete white
Size: 2.5 Gallon
I use this to keep my concrete from growing moss and mildew. Hope it works. At least it should be easier to clean. Note that it is important to follow the directions about temperature and applying 2 coats. After it dries water beads up on the surface. This is normally applied on freshly cured concrete, but I applied late. Love how easy to apply and clean up. Just soap and water. Cleaned out of the pump sprayer fine. ... show more
