Review: Impressive - A superior product. Goes on easily and drys fast. It cures into a rubber-tar based coat. I advise 2 coats. On corners, use the gause for added strength. This product was like painting Bitumen on the walls. Underground, this will last a hundred years and there's no way water will pass through a properly prepped wall! Color is black and fills voids, although a parge and repair should be used first then some gauze if theres a structural repare thats called for. When I purchased this, it was quite expensive. The price has come down since my purchase thus making it a better deal. Btw, thise using Blackjack, blackjack isn't in the same league! Wish I took some pics or did a video, just take my word on it as this was far from my first rodeo.
Review: Works great - I live in a 100 year old house and had experienced flooding in a ground level room. Apparently this had been going on for some time but previous owners didn't mention it. After getting quotes of up to $12k to excavate and repair the foundation (below grade) I decided to give it a try. After researching the internet I found this sealant and purchased the 5 gallon size. Next step was to excavate 25 ft long, about 18 inches deep, around where I thought the leak was occurring. I found several cracks and deteriorated concrete that I patched. Last step was to apply 4 coats of the foundation sealant using a concrete brush. Instructions say you can roll it on but it just seemed too thick so I went with the brush. My coats were probably thinner than what the instructions recommended but it looked really thick when I was applying it. Each coat dried in about 24 hours. You can tell when it's cured by the color change and it being dry to the touch. After the 4 coats, I back-filled the trench and waited for the rain. It's been 4 months and we've had several heavy rains with no leaks. So I'm calling it a success at this time. I ended up spending about $250 in materials so I'm glad I didn't contract this out. Maybe 30 man-hours to trench, patch, coat, and back-fill. I'm in my 60's so others may be quicker. Some noteworthy comments: I only used a couple of gallons when I had estimated I needed almost 4. Maybe my coats were thinner than they should be but appears to have been effective regardless; I used concrete brushes at about $10 a brush. I tried to clean the first one but this stuff is like a thick tar and wasn't worth the effort. I hate to put unnecessary stuff in the landfill but cleaning was just too difficult. I've got another area I may address similarly so I'm hoping the sealant will last a while after opening. Will probably be Fall project. Overall, a very good product, easy to apply and work with, and appears to have addressed my leak issues.

### ⭐⭐⭐⭐ Works well but, high sheen.
*by J***. on December 31, 2025*

Really nice sealant just wish it did not have such a high shine. If you prep the surface well, it goes on easily and seems to have very high adhesion. Worked quite well and now I will just need to wait and see how it holds up.
