What is the largest crack this will fix?

Asked by: fordycegma
as much material as the bucket will make. For a Deep crack, make sure you fill the bottom of crack with sand to within an 1" -11/2" of top to reduce material needed

20 lb. Gray Leak Stopper is rated 4.4 out of 5 by 27.
Rated 5 out of 5 by from Best concrete product I've used. Will definitely stop leaks... Best concrete product I've used. Will definitely stop leaks and seal cracks better than anything else on the market. It will set up fast, even in the rain. My only recommendation is to mix it in small batches and spread it quickly because it sets up increadibly fast. Great for septic work

It sets way too fast - like in less than a minute after mixing it starts hardening, making it very difficult to work with. It also cracks horribly after curing… I had to remove and re-plaster surface with another product.

Rated 5 out of 5 by from Hydraulic leak stop--Awesome product During the tropical storm that dumped 32" of rain, water was seeping up into my patio through a 1' x 4' rectangle the previous owner had left open. I had bought the product for a small crack, and had most remaining. Three inches of water was still in the hole, so I dumped in the mix and stirred in place. Within five minutes the water was stopped and has never even seeped. Cures so fast, it's a little difficult to do a large area, but even a thin amount will seal a crack. Buy it!!

Rated 5 out of 5 by from Works to fill cracks in cement even with water Upon opening the container the lid has a lip that makes it resealable. You could put the cement in ziploc bags for lasting added protection. The cement is a powder consistent with other brands. On the container it states hardens in three minutes and it does! Only mix what you can use in that time and wear gloves. I always mix with a polymer like sakrete bonder and fortifier as it makes it smoother and makes it adhere to the original concrete. I prefer to grind out the crack with an angle grinder than hammer it. On a horizontal surface I mix it to a liquid and pour it in making sure it gets down in the crack. On a vertical surface I use slightly less liquid and keep pushing it into the hole. Upside down I make it into a paste and work it in quickly. While it is wet you can smooth the surface or use a stone after it dries and then coating it with a thick paint to hide imperfections.
