Gorilla Waterproofing Spray, Black, 16 oz, Flexible Rubberized Sealant

Works good at filling smaller gaps (3/8" or so) so long as you give it about one minute between coats. It does as advertised. Might be good for other purposes if you use your imagination.

I have a fountain, the bowl had cracks around the perimeter, the material it's made of is almost soft; so, I sprayed the inside of the bowl & a 2" ring on the outside perimeter, thinking no more cracking from water (saturation) freezing as well as reinforcing the material. Finally, spray painted the black to a near color match. Will be sad when summer ends but anxious to see how this holds up over the winter. The rough texture is the natural finish of the bowl. This stuff is not thick like auto undercoating rather it's thin like paint,

Great to Have in the RV for Those Surprise Leaks This Gorilla Waterproof Patch & Seal spray is perfect to keep on hand in the RV for those unexpected small leaks in roof seams, vents, windows, gutters, and PVC joints. The aerosol gives a controlled spray pattern and a self‑leveling, rubberized coating that seals out water, air, and moisture, creating a flexible, paintable barrier that holds up to UV and temperature swings. It’s not a cure‑all for major structural issues, but as a quick, on‑board fix for hairline cracks and pinhole leaks, it’s very convenient and easy to use.

Excellent & very easy to use!

this was used to spray carpet used as a diy tent. Worked extremely well in the rain and storms

It works good but the can needs a lot of improvement it splatters and spits all over

Easy to use at varying angles. I sprayed it on the underside of a length of guttering that had rusted out in many places, and it stopped the leaks. Very easy to use and dries fast. I wish I could find it in colors to match gutter color. Can be used on a variety of materials and places. Once it is rain free here for an extended time, it will be sprayed on the barn's roof to stop leaks hopefully.

I will never buy this product again. I bought a 2-pack of the spray, and both cans had defective spray valves. There was a red dot at the base of the spray valve--usually that means you're supposed to align the valve opening with the dot. I did that, but the spray came out for only a couple of seconds, and it was splatters, not a fine spray. I shook the can, turned the valve a quarter turn and again, only a second or two of spray. After multiple tries, multiple re-orientations of the valve, the product was not coming out in amounts that would let me finish the job--sometimes nothing came out at all. I tried the second can and had exactly the same experience. Neither spray valve worked properly. Thirty bucks wasted.

Does not work

Quick dry and block spray nozzle. Glue is ok and Drum better than spray.

Applied to areas as described. The spray doesn't seem solid enough, and you need lots of cans to cover a relatively small area. I would go with a sealing paint with a mesh next time. Old ways always works. Not every "claimed innovative" solution works! Guys, stay at the tape product and stop producing products that undermine your reliability and brand name.

Parece buen producto, lo utilizamos para sellar por fuera una puerta corrediza q pasa el agua durante las lluvias, fácil de usar, esperando las lluvias para comprobar si funciona,

Just ok
