Gorilla Waterproof Patch & Seal Rubberized Sealant Paste, White, 1lb Can

Product arrived on time as promised; ez to use on my aluminum roof where had some overlaps and worried about water intrusion; applied with slim putty scraper, worked great.

As advertised. Quick delivery. Waterproof, and I would buy again. Thank you

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.

It was dry around the edges but actually it works well for what I needed it for. If you leave the unopened can in the sun for a bit it will soften up. I’ll buy more if needed. Time will tell as to how it holds up.

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.

As far as keeping water out, not a problem. It will do that, IF you can get to lay down.. The problem with this stuff is that it is like trying to spread an innertube. When I opened the new can, it wasn't even touching the inner can walls. The machine spit it in the can and literally hadn't moved from when it was put in. It is very, very thick and unspreadable. When using a putty knife and trying to spread it, it won't adhere to the base ( new vent flashing and new shingles). It just kept rolling up on itself, basically following my hand as I was trying to smear it. It is too think if your trying to push it into tiny cracks and crevices. I tried using a putty knife and sealing the inside of a rain gutter with it. It would not leave the putty knife and would just flatten as I tried to smear it. Even letting it sit in the closed can and in the hot sun didn't soften it up, it didn't want to budge. I ended up switching it out and getting a tube of flashing material for the caulk gun. It was much easier to work with, spread easily and I was done. This is the first "Gorilla" brand item that did not work out for me and I would not recommend it.

Follow the directions Follow the directions This product works great,,as long as you follow directions and clean the ever living h?!A out of area. I personally have not tried it for any medium to high pressure piping. I have used for old cast iron drain piping,,and outdoor concrete patio Just make sure area is super clean,,use some grit cloth and soap and water,, Let it sit for and hour then apply second coat. I have used it to seal some seams outdoor concrete patio storm door. I wouldn’t try the boat,,but I have a lot of faith in low pressure applications . The price is comparable with others and was packaged and shipped as described.

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.

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.
