GorillaWaterproof Patch & Seal Rubberized Sealant Spray, White, 14 Ounce (Pack of 1) - Seals Out Water, Air, and Moisture

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.

Works very well after a few layers

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.

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.

I tried the Gorilla Waterproof Patch & Seal and, unfortunately, it stopped working after just two minutes of use. I expected much better from this product. It did not hold up as advertised.

Can be used in place of the other stuff; Gorilla has good reputation and a quality product

I bought this to spray on my little shed after repairing it. The raccoons tore up a piece of my roof up and I had to screw it down. I then sprayed this on it. I am going to inspect it after the winter and see if there's any wetness in the shed. The roof looks secure for now.
