Gorilla Waterproof Patch & Seal Rubberized Sealant Paste, 12.8 Ounce Can, Clear (Pack of 1) - Stops Leaks, Flexible Gap & Crack Filler, Shrink & Mildew Resistant, Paintable

Application: The product is exactly what it claims to be—a thick, rubberized paste. It has the consistency of thick peanut butter, which is ideal for bridging small cracks, filling gaps, and coating larger areas where movement or weathering is an issue. I applied it using a stiff disposable brush and a putty knife, spreading it evenly across the problematic area. Be warned: it's messy, so wear gloves and keep mineral spirits nearby for cleanup. Since I chose the white color, it blended decently with the trim, though it definitely dries with a noticeably rubberized, textured finish, not a smooth, paint-grade look.

I used it to seal when I redid the ends on a gutter with a unique cross-section (can’t find replacement). I put it over where the metal layers lapped, not over a hole.

Ordered this 18 months ago. Just got around to opening it for the first time and the entire thing is dry and hardened. Seems it would have worked well considering how well cured it is inside the can but shouldn't have had such a short shelf life considering it was factory sealed...

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.

This would’ve been a great product to use because gorilla products are well-made, but the delivery must’ve been dropped and the product dried up in a hard ball but Amazon graciously refunded my money. Thank you, Amazon.

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.

This stuff is Fantastic, it sealed what 4 others failed to do. My storm shelter is now water roof. It took 2 years to finally find a good product to do the job!!!!

works great

I've had luck with previous gorilla products and this works too...

muy buena calidad y manejable

100 % garantizado Sella muy bien sin problemas

La pasta estaba casi seca . . . muy difícil de aplicar.

Clear paste applies over any surface. I will only know if it works if the cracks in my concrete widen with time.
