Solid performing solution
Recently ordered my second gallon jug of this awesome product. Sadly, I miscalculated how much I would need for my project and had to split it up over the course of a couple weeks, but the results are awesome. First time using a concrete sealer, this all in one solution makes it easy. Threw it in a sprayer and went to town on my garage and walkway. This second gallon is for the rest of my driveway. So far after a week of rain, the results are great! Water puddles up and bounces off the concrete. Now the first time I ordered this, it came in a product box and an Amazon box, which resulted to it leaking all over my brand new front porch which left a white stain mark due to poor delivery. I messages Amazon but nothing was done regarding this. Not the products fault as the delivery was to blame, but be careful and be sure to evenly spread once you apply. The packaging on the second gallon ordered was much better! Tightly packed in with more cardboard, I could tell they must have had issues with bad deliveries since mine. Glad to see it get fixed and will gladly recommend this product for future projects.

My go-to sealer for my chimney
Years ago, I used Thompson water sealer. The product changed over time; was milky and waxy when applied. I tried this product instead and have used it twice. The first time was for my chimney, which would leak when hit with high winds and driving rain. It sealed superbly; no leaks *at all*, ever. Then I purchased more to seal a concrete pad, and some touch up the chimney just in case. It's very easy to apply with a simple pump sprayer and performs exactly as advertised. This product is a winner; hope they don't change a thing about it.

Its really a Ghost shield
I used it to seal my newly built 24โ x 24โ garage, it requires 2 but i wish i bought to 3 to fully saturate during application. Its true ghost shield, when it dries you didnโt know itโs there. No strong smell, no film on the surface that makes slippery. Only one way to find out this winter what this sealer claims. I recommend use a 3/8โ - 1/2โ thick roller.
