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 RecommendIt worked exactly as specified on the label description. If you follow their directions, you can't go wrong. I used this to patch a hole in the back of an old chimney to a residential home. (vertical patch, near the ground). There were already slabs of concrete inserted to help fill in voids. I used expanding foam (the simple cans you can buy at home improvement stores) to fill in-between the slabs. The next day, I made sure to trim excessive foam away and make a recessed area. I then mixed the...

Wear mask & gloves!
Would RecommendThis product was used to seal a spot where water seeps into our basement. We put a first coating on. It mixed easily and we applied it to the wall. It took about a day to dry before we could apply the second coat. So far it has kept the water out!

Drylok Fast Plug is a Miracle Worker
Would RecommendI have used Fast Plug several times (over 10+ years), especially for patching cracks and damaged mortar in concrete blocks and the stucco covering them. It is very strong, versatile and excellent for many repairs. Love it! Recently I used it to repair a badly weathered concrete front stoop. Bees were flying in and out of a large hole! Also, a corner of the stoop broke off in my hand when the mortar supporting it disintegrated like dust! However, in conjunction with concrete caulk that Lowe...

Still leaks but hardens even in water.
Would Not RecommendI used it and still had leaks. I bought more and applied it and still have leaks. Its not that the product doesn't work, it's that water finds a way to route around. *sigh* So we found measures to eliminate the water source and it stopped dripping. Problem solved.
