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

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.

Strong chemical odor Use on well-ventilated area only Strong smell stays long time Product works well to seal any leak. Easy application, just spray, let dry.

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.

Pros-effective/ez spray delivery-fast to sf-safe pkg-!would buy again-fixed blown roof tiles above my hot tub-no spray smell- Cons-none but get 2cans for coverage. Done n fab product

This sealed a crack in a fountain basin. Still holding water.

The product is thin and kind of watery. I agree with other customers that this poses a problem on vertical surfaces. I was bothered by the paint thinner odor that hangs in the air after application. The odor eventually goes away but it's very pronounced. Be sure to wear a mask and apply this in a well ventilated area or you will regret it.

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.

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.

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.
