Gorilla Waterproof Patch & Seal Spray is a flexible, rubberized coating that seals out water, air and moisture. The applicator nozzle has a controlled spray pattern providing a clean, even coat. Before applying, shake well and spray 8” to 12” from surface. Be sure to allow the product to cure in between coats and before water exposure. Once completed, the self leveling formula smoothly covers small gaps and cracks ensuring a watertight seal. When dried, Gorilla Waterproof Patch & Seal Spray is paintable and temperature/UV resistant resulting in lasting repairs!
GREAT FOR: Metal, Concrete, Wood, Aluminum, Brick, Tile, Fabric, Rubber**, Glass and More!
**May not work for all types of plastics and rubbers
Not for continuous submersion or below-waterline use.
DIRECTIONS:
1) Clean surface of dirt, dust, grease and oil. Make sure surface is dried completely.
2) Shake well. Spray 8" to 12" from surface, covering evenly. A test spray on a disposable object is recommended before applying to your project.
3) Apply multiple coats to ensure all cracks and holes have been filled. Allow to cure in between coats and before water exposure. Full cure at 24 hours.
TIP: To avoid possible clogging, turn can away from body towards a disposable object, turn upside down and spray a short jet of clear gas after completing job.
NOTE: Test finished project with light water exposure to ensure all cracks have been filled. If test fails, apply additional coats. Do not use for gaps larger than 1/4". Apply between 50F and 120F.
PAINTING: Works with both latex and oil based paints. When coating with oil based paints, use a primer first before painting

This can clogged every few seconds and didn’t cover evenly, terribly bad spray design. I am looking at the paste for more uniform coverage, or maybe the kind you apply with a brush. Good in concept bad in practice as the rubber is too thick for the aerosol. Three stars because it did give some coverage and work somewhat as expected, but not as easy to use as it should be.Manufacturer should reformulate the suspension for easier spraying.

Used to patch a basement wall crack that was leaking water. Dried rock hard after 24 hours. I applied thick coatings. Make sure to shake the can thoroughly before using. If the nozzle clogs during application, shake the can again and pump the nozzle up and down while you're playing the spray. It helps it to stay clear. Strongly suggest wearing a mask if using indoors. The fumes are pretty strong and they are volatile. If you're working in a furnace area, turn everything off.

I used this for a concrete threshold doorway landing outside of my shed. This will keep water out, and I am 100% sure of that. I also bought the clear version and spray painted my front of the house concrete steps instead of using a sealer that lasted only 1 1/2 years. I used 3 cans of the clear for the steps. I'll bet this will outlast any sealer.

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.

We just recently bought a house there was/is 6 cracks in the concrete walls. The first year we had no problems the 1st spring here noticed 2 of them were leaking a little. So I thought I would give it a try on them. It sealed them up. The 2nd spring the first crack started leaking again, but it was from around the patch work. So I got some abrasive scrubbing pads for my angle grinder and removed the house hold paint a foot on both sides and sealed it again. Now the 3rd spring and no leaking. Redoing my basement bathroom now, it was completely unhooked. Scrubbing all the house hold paint off the wall and floor, then sealing them Gorilla Waterproofing. Afterwards I'm going to epoxy painting the shower. The sealant leaves a rubbery texture so I'm hopping the texture will come through the epoxy. We also used some clean sealant on the Temple's walls in the basement. Good thing is is wasn't a finished basement. This will be the 1st spring and so far so good.

Easy to use compared to the liquid in the cab version. But leaves orange peel texture on work surface.
