What Customers Are Saying

The Drylok Fast Plug hydraulic cement is a reliable product for sealing and waterproofing basement walls and floors. Customers report it is easy to apply, sets up quickly, and effectively stops active leaks and water seepage. The product adheres well to wet surfaces and cures rapidly, even in cool temperatures. However, it is important to work in small batches and apply it quickly before it hardens.

Great Stuff

Would Recommend

I have been purchasing Drylock Plug Fast for over 10 years. It’s never failed me, people who state it doesn’t work do not read the instructions on how to mix it. Biggest issue is use COLD water not room temp water.
