2) Using putty knife or trowel, apply to the surface. Ensure surface is completely covered and all gaps and holes have been filled.
3) Allow to cure in between coats. Full cure at 24-48 hours.
NOTE: Slight skinning may occur inside can if lid is not sealed tight. If present, remove skinned material to continue use and secure lid immediately after use.

Used to seal my roof and works well. Thank you.

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.

This is a great product for sealing, but it has a smell that will never go away (at least it hasn't in months) so you must not use it indoors. And it's brutally difficult to work with, resulting in sloppy repairs. It's so sticky and thick that you end up with it everywhere.At the end of the day though, it will create a very durable seal.

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.

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.

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.

After removing all of the old sealer material from the floor and trunk pans of my project car, I wanted to use something better than factory original which was pretty much like roofing tar. This had enough body to stay put even on vertical surfaces and bonded great to bare metal as well as epoxy primer. Pricey but the ease and convenience were well worth it

I used this for blocking holes in the rooftop where I drilled for the roof antenna 📡 It's been great so far. A thick black tar consistency.

Sà me sirvió para sellar un escurrimiento que tenÃa. La cantidad es más bien poca. Está duro, hay que aplicar con espátula metálica

La pasta es dura, no es moldeable, que le puedas dar un acabado muy terso a menos que la superficie sea de gran dimensión, para detalles chicos no la recomiendo.. pero si funciona solo avalarse que es una pasta casi dura.. yo la quise usar y solo perdà mi dinero porque a mi no me funcionó para lo que yo necesitaba. Para detalles sugiero el spray.

Se secó aún cuando no lo habÃa abierto, ni sacado del empaque.
