All Purpose Concrete, Brick & Stone Sealer, 2.5 Gallon Clear Penetrating Waterproofer for Porous, Exterior, Brick, Concrete, Stone, Cultured Stone, Sandstone, Limestone & Granite Siloxane Sealer

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!

Every time I get a new terra cotta pot or garden statue I coat it in this stuff. Keeps pots going for years because they don't have the freeze/thaw expansion of an untreated water-logged pot. It prevents moss from growing on the statuary so everything looks new...this can be a negative if you want things to have an aged look, but I prefer good things to last a long time.

Works well easy to apply

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

This sealer rolled on easy and smoothly. I like how “liquid” it was compared to other sealer. Rolls on with smooth roller.
