What Customers Are Saying

The Drylok Fast Plug product is generally effective at sealing cracks, holes, and leaks in concrete and masonry surfaces. Many users found it easy to use and that it worked well to stop water seepage. However, some noted it can be tricky to get the right consistency, though with practice it becomes easier to use. The product dries and hardens very quickly, so it's important to work in small batches and apply it rapidly.

would give more stars if i could

Would Recommend

This stuff saved me thousands! Our basement was starting to take water in at the floor/wall seams. Prepped, used this stuff and then sealed over it with a waterproof paint and the basement has never been so dry ! Not only does it not leak but no dampness, and very dry. Incredible what i might have spent ! GREAT PRODUCT !

Great for concrete patching

Would Recommend

Have used this Fast Plug many times. Currently using it to fill some holes in the concrete walls of basement before I paint them. Works great and fills the holes nicely. You just have to work fast with it. I have several places I have used this on and always a success.

not sure why this was given ony 1 star

Would Recommend

This is the 1st time I ever used this product and had a huge goof as I was confused how to mix it. I wasted ALOT at first but once I figured out how to figure out the mix ratio this stuff worked as advertised!!! I now have a dry basement and later this spring/summer I will work on the outside of the basement wall after digging and use some sort of membrane so I will have double protection!!! UGL Saved me BIG TIME!!

Fast Patching

Would Recommend

I bought this product after looking at the info on the container and, figured it would fill some holes I had in my garage wall after removing some stucco. This product was very easy to use and dried very fast for me. This is a very good product and easy to use for everyone. It is easy to mix, dispense and not wasteful. I think it served me extremely well for my project.

Definitely doesn't work if any water is flowing

Label says it stops leaks that are still flowing, I mixed everything and followed all instructions but this product just washed away before it dried and left a big mess surrounding the leak. I'll give this product another shot once I get everything dried out but I dont recommend it for anything more then moisture showing on a block wall

Did not go deep enough into the cracks

Would Not Recommend

I chipped a nice V-Grove into the cement wall that is below ground level - dry for weeks. Watched a ton of videos and did just like it said - looked really nice when all done. Nice rain and all spots still leaked. Removed the material and noticed it was to think to penetrate the crack itself so it was just in the v-groove. Need something that will go into the crack itself and expand and stay flexible.
