Clear Gorilla Waterproof Patch & Seal Liquid - 32oz

Steve B.: This is thick gooey stuff. I applied it with a paint brush, but you can't spread it as fast as regular paint. It seeps into cracks and really sticks to the surface you are applying it to.

I had some small leaks in a torch down roof and it fixed the leaks with a single coat.

Rushkami: We have tiles around our swimming pool with grout. After the blistering Texas heat some grout has fine cracks. We thought it would be a good idea to seal it up before the torrential rain.
Few tips:
1. Use a paint brush that you are willing to throw away, you cannot wash and reuse the paint brush.
2. You must finish your entire project in one go. The sealant thickens and dries.
3. Also, the lid may not close all the way back again, as the sealant thickens.
4. If you must stop half way, or for lunch etc, place it in a plastic bag and get as much air out such that you slow the drying time.
5. Oddly, does dry slowly on the grout itself. If it’s an outdoor project, and rain in the forecast the next day, then wait until you have 2 rain free days.
6. Wear disposable gloves. People - don’t ignore this tip. I almost stuck my fingers together, but Thankfully I was quick enough to scrape it off. Washing with water didn’t help at all, remember it is water proof.
7. Bugs may stick. Kinda gross, but next morning i stepped out to marvel at all hard work, only to notice a hundred beetles, critters, dragonflies, etc stuck. Spent a couple of hours removing them. It’s...

Andy Bickel: Gorilla provided a high quality seal between my basement floor and wall. I placed this over the cement sealer on the floor and painted over it. Paint sticks well. It was easy to use .

The only negative is it came in a dented can, but the product was good and provided a quality seal. Highly recommend!

Kindle Customer: I had a roof leak in a localized area. Quote from the roofin contractor was very pricey. I used the gorilla product. It took one hour and thus far all is dry. It was east to apply and will keep watching it.

Marsse: As luck would have it, when the guys were installing the new roof on my rv they actually put 4 small holes in my slide out roof. I used this to repair the roof and it worked perfectly Highly recommended

Ellen B.: Works exactly like it says. Easy to pour and spread, perfect, plastic water proof seal. Poured mine under the kitchen sink cabinet where there was bare chipboard floor where the laminate floorboards stopped, to protect from water leaks. Got tested basically as soon as it dried and worked exactly as planned. Couldn’t be happier.

NeilNeil: Product does what it says. Self levelling which makes the job easier. The can was very damaged. I don’t know whether this will affect shelf life. The box it came in was fine so I don’t think it happened in transit.
