Gorilla Waterproofing Spray, Clear, Flexible Rubberized Sealant, 14 oz | Paintable and UV Resistant, Seals Water, Air, and Moisture, Ideal for Roofs, Gutters, Skylights, RVs, Windows

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 have a water feature that my Dad made for me twenty years ago. I was never able to use it because my old house did not have outdoor electrical. It was made with a galvanized metal bucket as the base and through the years of storing and moving it developed a leak in the bottom seam. Was sure I would have to replace the base, but this worked well, only did two coats and it has not leaked, not even a drop.

Review: I recently tried out the Gorilla Waterproof Patch & Seal Rubberized Sealant Spray to patch up some tiny rust holes in my gutters, and here's my balanced take: Pros: Ease of Use: This spray is incredibly easy to apply—no messy brushes or applicators needed. Just shake, spray, and you're done! Versatility: It works on a variety of surfaces, including metal, concrete, wood, and more. Perfect for sealing gaps and cracks in gutters, roofs, and even outdoor gear. Quick Drying: Dries relatively fast, allowing you to move on to the next step of your project without long waits. Self-Leveling: The formula levels itself out, ensuring a smooth, even coat that covers small gaps and cracks effectively. Cons: Multiple Coats Needed: For optimal results, you might need to apply multiple coats, which can be time-consuming. Runny Formula: Some users found the spray to be a bit runny, which can affect its performance on vertical surfaces. Clogging Nozzle: The spray nozzle can clog if not cleaned properly after use, making it less effective over time. Tacky Finish: In some cases, the sealant remained tacky even after drying, which can be inconvenient. Verdict: Overall, the Gorilla Waterproof Patch & Seal Spray is a handy product for quick, reliable fixes around the house. It worked well for patching tiny rust holes in my gutters, sealing them up nicely. Its ease of use and versatility make it a go-to for minor repairs. However, be prepared for potential issues with multiple coats and a runny formula. If you're looking for a straightforward solution for sealing leaks, this might be worth a try, but keep in mind it might not be perfect for every situation.

Used on garage roof. Works well.

Works effectively and quickly. Good to covering gaps and sealing it up. Wear disposable gloves! It easily get on your hands.

Didn’t work to good on sealing a metal planter. I put several coats of, still didn’t seal it completely.

This is now the third winter since I applied this sealant in several places on an aluminum storage shed. I live in an area of arctic type winters and rain forest summers. Three years and it is not showing any signs of degradation. NO LEAKS. NO CORRESION around the patched areas. It has yellowed just a little bit but I do not care about that. I even used a little to seal up a hole over a wood patch at the base of my garage wall to keep the field mice out. I don't think the little critters like the stuff much because they did try to chew it a little at first but then gave up. That was the summer of '24 and the patch is still there....and the mice aren't.

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.
