Gorilla Waterproof Patch & Seal Rubberized Sealant Spray, Crystal Clear, 14 Ounce (Pack of 1) - Seals Out Water, Air, and Moisture

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 purchased this Gorilla sealer to stop a leak in a gutter. It worked perfectly. It was so easy to spray on to seal the gutter seam. I sprayed it while weather was warm and dry when there was no threat of rain for a few days. I will definitely purchase it again when a need arises.

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.

I used the Gorilla Waterproof Patch and Seal Rubberized Seal on my outside storage and it worked perfectly. It was easy to apply and sealed the area quickly. Once it dried, it formed a strong, flexible, waterproof layer that holds up well outdoors. It’s been exposed to rain and changing weather, and the seal is still solid with no peeling or cracking.

used to seal a leak in a concrete bird bath. 24 hour cure time is tedious, but it worked fine for this application.

Used the whole can on a leaking concrete fountain with a thin little crack. Did multiple thin coats, did not work at all

This stuff is awesome. Very easy to use. Looks nice and creates a nice seal

I've used this product before and seldom have any issues. When i do, it seems the spray comes out more like a hose stream and not a spray nozzle. I shake the can constantly to try to avoid this and it's probably the makeup of the product. Nonetheless, this project was to seal any rust areas in this old HVAC overflow pan rather than spend $400 to replace it and the product sealed the pan as planned from what i can tell. I've used it inside gutters as well when the joints leak with age and it seems to cover and hold up well.
