Gorilla Patch & Seal Liquid Rubber Waterproof Sealant, Crystal Clear, 32 Ounce (Pack of 1) - Seals Out Water, Air, and Moisture

Used this on my two sun windows on top of my sunroom. A huge leak appears around one of the windows after 19 years so I taped off around inside the window about a 1/4 inch in and applied the rubber sealer with paint brush on that 1/4 inch to the sunroom window frame and the leak stopped. A week later we had a 1 1/2 very hard rain and inside sunroom stayed dry. It painted on easily, had the lid off for 1/2 hour while using it and no dry ups in or around the can. It stuck to window and metal sunroom easily. It is thick enough to not cause run off as my sun room roof does tilt down. Great product.

This is an excellent product. I used it to repair the bottom in my lawn bag. Better than new. I will buy it again when I need a product like this and I would recommend it.

I’m giving 5 stars because it works really well but there is a BUT, it is very difficult to apply using a roller, I used a foam roller and if your thinking it will apply like paint your sorely mistaken, I started with the spray cans but was getting pricey so I switched to this it’s very hard to work with it leaves clumpy build up but as long as you back roll it all lays nice and flat it goes on heavy so 1 coat only for me if it works, as well as the spray cans then it was worth the troubleForgot to mention that the cans were dented does take a long time to dry/cure been 2 days and it’s still slightly tacky, I used it on some concrete stepping stones loved the spray cans not sure about this stuff, if it dries thumbs up time will tell, water beads up nicely after using spray cans hope this acts the same way

It did a great job overall and better than expected

We have tiles around our swimming pool with grout. After the blistering Texas heat some grout has fine cracks. We thought it would be a good idea to seal it up before the torrential rain.Few tips:1. Use a paint brush that you are willing to throw away, you cannot wash and reuse the paint brush.2. You must finish your entire project in one go. The sealant thickens and dries.3. Also, the lid may not close all the way back again, as the sealant thickens.4. If you must stop half way, or for lunch etc, place it in a plastic bag and get as much air out such that you slow the drying time.5. Oddly, does dry slowly on the grout itself. If it’s an outdoor project, and rain in the forecast the next day, then wait until you have 2 rain free days.6. Wear disposable gloves. People - don’t ignore this tip. I almost stuck my fingers together, but Thankfully I was quick enough to scrape it off. Washing with water didn’t help at all, remember it is water proof.7. Bugs may stick. Kinda gross, but next morning i stepped out to marvel at all hard work, only to notice a hundred beetles, critters, dragonflies, etc stuck. Spent a couple of hours removing them. It’s Texas y’all!8. Dries clear. Yay!9. Has a mild shine during daylight. I don’t mind that though, but if you find matte tiles and a mild shine in the grout not your vibe - then just know.10. Toss all remaining/leftover solution. Really don’t want to risk sticking to random things in the garage.

Did everything right, it just wasn't an even coat so will do another. It was sticky/tacky for days so I wasn't sure if/when it dried. Still tacky after over a week. Is that normal?

Local hardware store wanted $36. Amazon dented can was $24. Sealed an aluminium roof. Will use it on a few other jobs.Can recommend!

To write this review, I did a search for fountain sealant and it showed up as it did before I bought it. This product is not good for sealing a fountain since it dissolves and breaks off in pieces inside the fountain, potentially clogging the pump and fountain besides not properly sealing a leak. I am sure this product works well for some projects as most Gorilla products do, but it does not work for sealing a fountain.
