Damtite 07502 Gray Waterproofing Hydraulic Cement, 50 lb. Pail

This product did a great job on my pool repair. Was very easy to mix and use. Works as advertised.

Excellent product it does stop leaks, easy to apply and what I like most about it you can apply a second and third coat after it dries if needed. (Important) mix small batches each time it set up between three and five minutes. This product is much better than anything you can buy at Home Depot or Lowe's!!

Worked just like they said it would. Make sure to use in small increments or It will get hard fast on you

This product worked great. However, I found the same type of cement at a local store for half the cost and almost twice the bucket size.

I have a rather large outdoor fountain in my dining room. (Always wondered why people put water fountains outdoor where they spend so little time.) I enjoy this fountain year round, night and day. Been in use for over ten years. Started getting a very small leak from a tiny crack. I emptied the fountain, followed instructions and presto! No leaks. I put 3 thin layers on the bottom, allowing each one to dry thoroughly before applying the next. But be quick-this stuff SETS in like 15 minutes. Directions indicate you can repair with water inside a pool, etc. but I chose to do the 3 outer layers and one inner layer. Sure have ALOT left over. Goes a long way.

Works great , easy to use would purchase again if needed.

This stuff appears to be awesome. Looks great , applied super easy and smooth. This is the first day. I applied it to sidewalk and inground pool

I used it to patch a concrete water tank.
