Gorilla Waterproof Patch & Seal Rubberized Sealant Paste, Black, 1lb Can (Pack of 1)

Make sure to wear gloves, very hard to get off your hands. Works well so far. Very hard to spread.

I use this in a small area in my outdoor fountain and it works great. It's very thick and stays in place.

The media could not be loaded. Not to easy to apply, when I opened it appeared to be hard and dry as if the can had already been open or was old. It was very sticky and would curl when I tried to apply and had dry hard clumps My can definitely wouldn't spread easy. This morning it appears dry and rubber like texture so I'll see how it holds up. Time was an issue so I made it work.

I don't know what the shelf life of this stuff is, but this had more than a quarter inch dry crust all the way around it. It was shaped in the can like a white Hershey kiss, and hard all around. I broke through it to see if any of it was usable, found about a half a cup usable. I didn't get the job finished with such a tiny amount. Not a good value! I use Gorilla glue almost every day and it is the best! Not so with this.

THE PRODUCT IS EXCELLENT BUT WAS ACCIDENTLY DELIVERED TO A NEIGHBOR'S HOUSE

Update 7 Oct 2024: I visited the gorilla tough website and discovered that their email and chat interfaces DO NOT WORK. I made time to call their 800 number and finally reached a rep. The Gorilla Tough rep asked for the number on the bottom of the can, so make sure you can read at least the first 5 digits. Therein, the rep provided me with a very generous credit, wherein, I had my choice of Home Depot, Walmart, or Amazon. He said they would also send an envelope, so I could ship it back to them for examination. The paste is a failure, but when you finally reach a rep, the company makes up for it!I trusted Gorilla Glue products up until now. When I first opened the container, I noticed the product was very stiff. Not knowing the consistency to expect - and trusting the brand from other Gorilla Glue products I've used in the past, I still maintained trust in this "Gorilla Paste" for some reason. Over the course of a month, it became more difficult to use. About 6 weeks later, it was nothing but a hard lump of rubber as you see in the pic. I did manage to use it in a few places wherein it definitely sealed some cracks, but I didn't get my money's worth.

I bought this to repair and hold a small long crack on my porch step. This product was easily applied with a putty knife. I did one wide layer in cold moist weather. Dried in 48 hours and it has held up! I have also used this to seal areas in my gutters.

Having a small leak in an difficult spot on the roof meant I needed a good, easy solution. This seems to work well. It went into the small crevice quite well and seems to have solved the problem. This may well work for your problems also. Cannot hurt to give it a try.
