DRYLOK Fast Plug is a fast-setting hydraulic cement that sets in just 3-5 minutes, preventing water from flowing, even under pressure, through cracks and holes in concrete and masonry structures. It's ideal for sealing floor and wall joints, patching settlement cracks and holes in masonry walls, and anchoring metal to masonry. Similar to mortar, it sets and hardens extremely quickly.

by|Nov 8, 2023

Answer This Question
A: Hieu - Since DRYLOK® Fast Plug is in a powder form and requires water to mix, any unused product will keep as long as it's sealed in the container and kept from moisture or water.

Q:Will dry lock bond to old hydraulic cement? How thin can you make it without cracking or breaking out? The application is maintenance on a wrought steel guardrail which is rusting under the existing hydraulic cement. Is this the best product to use?

Answer This Question
A: Fred - Mike (community answer) makes some good points. If the existing hydraulic cement is failing or crumbling, it's best to remove and replace with properly mixed material. It's also a great time to address the rust before reinstalling the railing. When mixing DRYLOK® Fast Plug, please use a 3:1 ratio (3 parts powder to 1 part water) and use quickly. Hydraulic cements do not "top bond", they expand inside the hole or crack therefore "locking" the patch in place. In your application, the hydraulic cement expands in the hole and locks the railing post in the hole - a perfect application for DRYLOK® Fast Plug.
by|Oct 5, 2023
A:Â Adding more hydraulic cement to an already existing problem will not solve the problem. The old cement must be removed and new applied. In addition the railing should be removed and any rust issues taken care of before resetting it in new cement as the rust will continue to grow and eventually cause the railing post to fail.

Answer This Question
A: DRYLOK® Fast Plug can be used to fill large holes but must be built up in layers. I suggest speaking with a Home Depot associate for other materials that may be a better choice.

I have a 120 year old house and over the last few years alot of water started entering my basement. A reputable waterproofing company came out and gave me an estimate for nearly $20,000 to do interior and exterior waterproofing. A friend of mine has a home almost as old and mentioned trying dry lok. I am amazed by this product! We have had several rainstorms since using it, and not 1 drop of water has seeped through the cracks. I love it!

works well, as advertised. I'd only wish it had a slightly longer cure time when mixed as directed.
