Fast Plug Hydraulic Cement

Powder form. Come with measuring scoop and easy to mix. Sets up in about 5 minutes. Mix only small amounts so can be applied before setting. Dries black in color and very hard. Make sure your application is formed the way you want it. Can not scrape or change once set. Can paint over but requires several coats. When dry it looks like it will be very waterproof. 4 lb. Container does not cover a very large area. Probably not economically feasible to cover large areas. I put a thin coat of this product on area. Then finished filling in with concreat patch. This allowes you to cover a bigger area and works well.

I have a small water fountain project where I used some leftover bricks and mortar. I noticed that even though I fully cemented the inside bowl, the cement is still way too porous and water would seep out of the bowl pretty fast at a rate of about 2 gallons per day. I searched Amazon for a solution and came across this Drylok. The price seems reasonable and I didn't need much so I gave it a go. I am very surprised at how effective this is. I mixed the powder inside the bowl itself and used a paintbrush to spread the (rapidly drying) mixture around the perimeter. This thing dries really fast (5 mins). I was able to fill it up with water just 10 minutes later and it's been holding up fine since. No more water seepage and whatever water is lost is just lost from evaporation, which is very little. Just to give you an idea of how much powder you will need for your project: This bowl has 8 gallons capacity (about 15"x15"x12 interior dimension) and I used half the bucket of Drylok to cover it. I also used a paintbrush to get an even coverage because there's no way you can smooth out an inside bowl with a trowel with a rapidly drying cement like Drylok. Overall I'm very satisfied with how this turned out. I will use the leftover powder in another fountain, it works so good.

this stuff works, its for real, make only a little bit, mix and use immediately, this stuff dry's very fast

I recently tackled some persistent water leakage issues in my basement with DRYLOK 00917 Cement Hydraulic Waterproof. Here’s my take, granting it a solid 4 out of 5 stars for its performance. Pros: Efficiency: DRYLOK delivers on its promise. Once applied, it created a robust waterproof barrier that effectively stopped water ingress in previously problematic areas. Ease of Use: The product is straightforward to mix and apply. Even as a DIY enthusiast with moderate experience, I found the process manageable. Cons: Preparation Work: The success of DRYLOK heavily relies on surface prep. I had to spend considerable time cleaning and smoothing the application area for optimal adherence. Application Thickness: Achieving the recommended thickness for maximum effectiveness required more product than anticipated, affecting overall project costs. In summary, DRYLOK 00917 is a reliable choice for waterproofing needs, particularly for basements and other concrete surfaces prone to moisture. While it requires thorough preparation and a bit of patience during application, the results justify the effort. It’s not without its minor issues, but it stands as a solid investment for long-term waterproofing solutions.

Very messy but works well.

I never did any sort of mortar cement work before and I was intimidated, but using this product made it easy and it came out so well!!!!! I have stone steps to my front door and the joints where broken and loose, so I chiseled it all out and used this to fix it and it came out so good. One thing I will say is I ended up needing 2 full buckets of this product to completely my re-joint the stairs so it makes a lot less than you would think. Also, because it dries within 3-5 minutes make sure to only do 1-2 mixtures at a time (3 scoops: 1 scoop water) otherwise if you're slow like me you end up not using it all before it gets too dry in the mixing bin.

Works well on my outdoor the fountain and planters.

We discovered water coming in around the outflow pipe to our septic system, where it penetrated the foundation. Whatever hydraulic cement had been used to seal around the pipe back in 2004 was no longer standing up to the water on the outside of the foundation when we got heavy rains. I followed the directions on the package, and applied a layer of this over the existing material. 48 hrs later, and for the next 6 weeks, we had a lot of rain on Cape Cod. But this repair seemed to be keeping the water out just fine. We won't be back at the house again until the spring, so I'll update the review if I find evidence that the repair is no longer water-tight. But my initial experience was very good with this product.
