UGL DRYLOK Fast Plug Hydraulic Cement, 4 lb – Stops Water Leaks Instantly, Sets in 3-5 Minutes, Ideal for Masonry Cracks, Gray

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

The media could not be loaded. 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.

Concrete foundation had two long cracks one has water seeping in. Followed the directions on dry lock container. Easy fix problem solved

Overall it works as advertised.Dries so fast it makes you have to keep mixing with water or else only mix in small batches. Took me 8 hours to patch up the cement board joints for a shower remodel. I’m in a bit of pain the next day. Kind of wish I had just waited and got a different brand that takes longer to set.Also, the way it dries causes it to look inconsistent. If it’s too wet it doesn’t properly fill in cracks enough and just spills all over. As soon as you get the mixture the way you like and apply to a small area, it’s dried so much it’s harder to work with. Very small window for optimal use. From the looks of the way it dried in the end, when you apply it too dry, the finish is a lot more rough and brittle looking. See my photos.The inconsistency isn’t so bad for a shower job since it’s going to be covered with tile, but for exposed repairs, this would look bad. It’s fairly hard to keep the finish consistent. Use for small jobs only.

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.

During the winter months and early spring as well, concrete tends to breath and exhale, thus giving way to cracks and leaks from the frost line as well... This bucket is quick and to the point to plug up cracks and thus preventing basement flooding.

Got this because I read it could be used to make a small fish pond form/liner (not mfr statement). With that said I was disappointed, as you can probably imagine. The application was GREAT and smooth but after using three of these it was just not thick enough and cracked in areas where too thin. I then had to use flexible rubber seal over it and that ended up working ok. If you're looking for a cheap quick way to create a form or liner this is NOT the way. Lesson learned. Otherwise it's a great product.
