Great sealer
This sealer is working well so far. It was easy to apply and looks good.

Amazing and it holds up
Used on a pool deck for a saltwater pool. Amazing results, even with one coat. Take your time to make sure you get good coverage. I used a sprayer. Water repellency is amazing and lasts a season even in high traffic areas

Easy and so far effective
Application was easy for a novice using a roller and went on even, covering my patio in two coats as instructed. So far has been good for water repellant and dirt cleanup, and did not change the color or sheen of my concrete. Would probably rate a 5 , just need to see how it goes after a few more months.

It seals cement
I decided to remove all the terribly installed flooring in my bathroom. Took it down to the bare slab. Was leery on installing new flooring since the last one leaked/trapped water and created an awful rotten smell. Decided to just leave it bare for a while and see how I like it. Just to keep the water from soaking in I used this stuff, and it worked like a champ. Water that isn't caught by our bathmats or runner rug just pool up nicely on the surface. Eventually just dries up or is easily wipe up. I just wish they had a smaller container of the premixed stuff; I got a ton left.

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.

Great sealer
It totally seals the area you use it on and it does not show (under dry conditions). Of course, if it rains you can see which is sealed. I rolled it on and it was so simple and easy, but be sure to read the directions because it was a little different than I expected.
