Rated 4.8 out of 5 by 10 reviewers.
Rated 4.0 out of 5.0 by Works great, even when used for what it wasn't intended. In my closet, the back wall of that closet was against my Farmer's porch. The closet was always cold. So I ripped out the drywall to find no insulation at all. also, at the bottom of the closet where the floor meets the wall, there was moisture. Basically the wood floor ended, there was a gap and then I could see where my porch slate started. I mixed this up and poured it into the gap to fill it and lock out any more moisture. It mixed and spread great and sealed all the empty space. I would imagine this will work great. Next step is to seal the outside as well. January 8, 2014
Rated 5.0 out of 5.0 by Cures underwater I've used this project to seal leaks in concrete floors and walls on many small projects. It is great for sealing small and large cracks. It can be applied underwater too. It cures based on the temperature of the water: hotter is faster. It also works fine when the surface and patch area is relatively cold. It clings to coarse vertical surfaces too. There are only a few things to remember: 1. Work quickly or it'll cure in your mixing bucket after just a couple of minutes. 2. The pressure of the water flowing out of the crack can push the mixed and hardening drylock out. 3. It's cement and you should wear latex or rubber disposable gloves and a painter's breathing mask. Eye protection goggles are good too. 4. Use a disposable mixing bucket because the left-over has cured and is is attached to the bucket. 5. You only mix drylock and water. You don't need to add anything else as with regular cement. Beyond safety, the most important thing to note is that it will take a day or so before it fully cures. You may get a trickle of water until then. January 13, 2015
Rated 5.0 out of 5.0 by Works well even in wet nasty areas I used this UG Drylock Fast Plug Hydraulic Cement in a wet nasty place; the distribution box for my septic system. The pipes coming out of the distribution box were loose. It is not like one can clean the old concrete box up well, but the dry lock was able to bind and cure and hold things in place. March 2, 2012
Rated 5.0 out of 5.0 by Appears to work I used this product to fill a hole in the bottom of my basement wall. The hole was drilled from the inside to hopefully channel water from inside the blocks to the new drain outside. The contractors had filled the 1 inch hole with silicone but after it rained there was noticeable seepage from the hole. I removed the silicone and used this product instead. I also used this product to close a small gap where the same wall meets the floor. I am sure that the cement will stop the water in the drilled hole and am hoping that it will keep water out of the corner too. Again, I am only hoping to stop the water on the inside of the wall long enough for it to find the nearby outside drain. I used a margin trowel to mix the cement in a bucket and used rubber gloves and my hands to apply the cement to the wall and to spread it into the corner. I covered the dried cement with the same waterproof coating as the walls. August 15, 2012

Rated 5.0 out of 5.0 by Drylok Fast Plug Pond Repairs I used it to repair cracks at the base of my waterfall pond. Powdered mix is easy to prepare but mix only what you can use immediately as the product sets up fast. Smooths out easily for a nice finish. I covered this patch with Drylok waterproofer latex paint.

Rated 5.0 out of 5.0 by Easy to use and works well I used this to repair cracks in the cement retaining wall that wraps around our driveway. It was covered with fine cracks and had quite a few larger cracks as well. I'm a new homeowner with very little experience with this type of repair, but this product was super easy to use, and it is holding up well. June 21, 2014
