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 used this to seal a couple of leaks that I had in a valve assembly on my pool equipment. This was a multiport valve that is about 10 years old and has developed a couple of very small leaks. I followed the directions and put 3 coats onto the areas that I knew were leaking as well as some of the areas that I could see were susceptible to failure (the valve is in 2 sections that are glued together). It adhered to the surface very well and I allowed 36 hours to cure prior to restarting the pump and there are no leaks! We'll see how well it holds up but so far I am very happy with this product. It was used on something that was black so I can't really say how "clear" it really is, but it looked fine for what I was doing.

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 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.

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.

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.

It worked great for me, and I like it.

0 stars out of 5. Doesn't work I wasted a whole can trying to fix a crack in a water fountain and after 5 thick layers it's still dripping water. Look for another product. I only put 5 stars because Amazon puts the 1stars reviews all the way down.

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.

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

I just used it on a leaking toilet seat tank. It was very missy and hard to get it to Narrow areas with out a dispenser I strongly recommend buying one with a smart dispenser
