I have latex base Drylok masonry waterproofer on my basement cement floor & cinderblock walls already, can I apply Drylok Fastplug hydraulic cement over it?
Asked by: wetbasementRotterdam
Yes, and you can then apply the Waterproofer over the Fast Plug to maintain the sealing and aesthetic properties.

How long before you can paint over it?

Asked by: Ron
This entirely depends on whether the defect you sealed is still weeping. If so, you'll want to wait for the Fast Plug to dry to a consistent color - or mostly so. I applied two coats of the DRYLOK latex waterproofer over the Fast Plug.

What is the largest size hole that can be filled?
Asked by: Pete
Pete, there is really no “maximum” amount of a hole to fill. If it is a very deep or wide area exceeding 3-4”, it would need to be filled first with a concrete mix to obtain a “base” and then fill the surface with the Fast Plug in layers if needed to make the repair flush with the wall.

4 lb. Fast Plug Hydraulic Cement is rated 4.8 out of 5 by 17.
Rated 5 out of 5 by from Product worked well. I have 10" thick poured concrete basement walls on a 2013 construction home... Product worked well. I have 10" thick poured concrete basement walls on a 2013 construction home in Michigan. One of the tie rods at shoulder height had began seeping water this winter (2017-18). I used a wire brush to clean the area. The wire brush actually knocked away some of the debris that was helping to slow the leak, so cleaning the area actually made it leak more/faster. I initially mixed the product with colder water, and let it rest for a minute as the instructions indicate. Then I tried to push the wet mix (maybe the consistency of peanut butter) onto the leak/wall. The leak was coming in so fast that it watered down the mix and washed it away, so I needed to start over. I re-mixed a second batch, but this time I used warmer (not hot) water. Again, I let it setup for about a minute and the warm water stiffened the product much faster. (This time about the consistency of Play-Doh). I slapped a glop of the mixture onto the leak/wall and held firmly for about 5 minutes. The leak stopped. After the 5 minutes of holding the product was too stiff to be able to smooth/mold like you would joint compound on drywall, so the repair is a little ugly. But a lot better than water coming into the basement. I covered the spot with some Drylok water proofer (paint). Basement is nice and dry.

Had a water leak in my basement wall( below the window) which looked like a previous plug might have worn out. Filled in the plug/hole with the DryLok and held it in place for 3-5 minutes. Water stopped. Will let plug set for 48 hours and paint with DryLok waterproof paint.

Rated 5 out of 5 by from 5 ft crack I found a 5 ft crack in my finished basement wall. The previous owner used expoxy to seal the crack but did a terrible job. My wife found this hydrualic cement. So I tried it and man did it work awesome. They dont lie when it says sets in 3-4 minutes. This stuff is great.

Though somewhat hard to find in local Home Depot stores, the product works as advertised! Applied to still-weeping cracks in the floor, DRYLOK Fast Plug nevertheless setup and cured - though requiring an overnight cure time. One caveat we discovered: mix only the minimum three cups of powder to one cup water as more mixture than this will set before it can be adequately troweled. We also determined that cold water does extend the workability somewhat. Finally, the DRYLOK recommended mix ratio, 3 to1 product to water, is dead on. Any deviation from this ratio makes the mix difficult to apply. DRYLOK clearly knows what they're doing!

Rated 4 out of 5 by from Works great, even when used for what it wasn't intended. In my closet, the back wall of that closet was against my Farmer's porch. The closet was always cold. So I ripped out the drywall to find no insulation at all. also, at the bottom of the closet where the floor meets the wall, there was moisture. Basically the wood floor ended, there was a gap and then I could see where my porch slate started. I mixed this up and poured it into the gap to fill it and lock out any more moisture. It mixed and spread great and sealed all the empty space. I would imagine this will work great. Next step is to seal the outside as well.

Rated 5 out of 5 by from Cures underwater I've used this project to seal leaks in concrete floors and walls on many small projects. It is great for sealing small and large cracks. It can be applied underwater too. It cures based on the temperature of the water: hotter is faster. It also works fine when the surface and patch area is relatively cold. It clings to coarse vertical surfaces too. There are only a few things to remember: 1. Work quickly or it'll cure in your mixing bucket after just a couple of minutes. 2. The pressure of the water flowing out of the crack can push the mixed and hardening drylock out. 3. It's cement and you should wear latex or rubber disposable gloves and a painter's breathing mask. Eye protection goggles are good too. 4. Use a disposable mixing bucket because the left-over has cured and is is attached to the bucket. 5. You only mix drylock and water. You don't need to add anything else as with regular cement. Beyond safety, the most important thing to note is that it will take a day or so before it fully cures. You may get a trickle of water until then.
