Waterproof Patch & Seal Rubberized Sealant Spray, Black, 16 Ounce (Pack of 1) - Seals Out Water, Air, and Moisture

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 was Expecting better. I have A crack in my plastic fountain tub. It was cleaned and sandpapered a bit to help adhere. I did multiple coats x4 days letting them each dry before a re spray. After day 6 I filled Tub with water and within a few hours it was leaking again. Emptied the tub, then let sit for 2 days and used the waterproof gorilla tape and that worked like a charm!! But this spray didn’t work on my fountain tub or garden hose and was a waste of money.

Does not work

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.
