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.

Sealed off what I needed it for and set up fast so you have to hurry to get it on or it will dry that quickly

Works as advertised. Easy to mix and apply. I coated a concrete bird bath that was pitted. Applied with a putty knife and smoothed it out with a disposable paint brush. Looks fantastic!

Good, not perfect

Would Recommend

Good product and worked as described. However, it was difficult to get the mixture correct for the right consistency for application. Also, some of it crumbled after applying and drying. So there was a fair amount of clean up afterward
