RubbersealLiquid Rubber Waterproofing and Protective Coating - Roll On (32 oz)

I bought Rubberseal Roll On to coat the inside of a plywood vivarium (48"L x 28"width (depth) x 72"H). I needed water resistant top and sides so coated the top half with 1/32 of an inch (30 mil) and the lower half and bottom with a thicker coat of about 1/16 of an inch (60mil) to get a waterproof seal. I used a roller for the top sides and a brush to coat the corners. A brush will let you lay this on thick. I have some very thick areas on the bottom especially in corners where plywood meets the frame. Be aware this takes at least 72 hrs to dry and not be tacky to the touch and depending on thickness can take longer.Other products I used with Rubberseal Roll On:I was concerned that silicone will not adhere to the rubber but it worked beautifully. I used GE 100% Silicone I (black). I added cork sheets to the upper walls and coconut coir over the silicone in other areas.Great Stuff adhered with no problem also. And once carved and shaped you can use the black silicone to blend it in. I used globs on the walls and used them for plant anchor points.Liquid Nails will adhere to the rubber also, but takes a bit for it to get a good grip. you may need to tape things in place till the glue dries.Tips:you may scratch the rubber off the walls with decor (adding large branches and such) if you are not careful. Silicone can touch up these spots or if you have some RubberSeal left over you can re-touchup as needed.Wear gloves as this becomes extremely sticky and buy 3 or 4 cheap paint brushes or rollers for each day you are going to add a coat since the RubberSeal will dry to the brush/roller and make it unusable after a few hours.The one gallon can I bought was just enough for this size build. I could have used another quart to really get a thicker coat all around but for my purposes this was enough. Keep in mind I had a large acrylic front door so I didn't need to coat the front of the viv all that much. If you plan on using it for a plywood aquarium this size you would need 2 gallons or more to get 60 mils+ all over (1/16"+).Overall I am very pleased with the product, especially since I used it in an unconventional way.

I was able to use it to seal up a small waterfall with no problem. I gave it three or four coats waiting an hour between each coat. The only issue I had was that once I was done I had to throw the brushes away. Each coat needed a new brush. No way to clean this stuff off of it. Thank goodness for dollar store paint brushes. It did look brown when painting it on but it dried black. I gave it several days to fully dry as it tended to stay a bit tacky even in hot West Texas weather. Once I was satisfied with it I went ahead and spray painted it the color I wanted. (The waterfall I built has a red lava look.) Seems to be pretty good stuff, but your brushes are trash. Fortunately, the job I did wasn't finish work and could be sloppy. Cleanup might be a pain with this stuff.

I used this product to repair a roofing leak. I have used other products in the past, but nothing near as easy to apply and has the same results. The large pail is pricy but product seems superior to anything I've ever used. It dries quickly and remains rubbery and very pliable. Other materials turned out dry and hard. And then later cracked. I have two room additions on our vacation home. The roofing seams expand and contract with the seasons. I believe that the elasticity of this product is what separates from others. Again, while I thought it was expensive, but the quality and ease of application makes it a worthwhile choice. I have two more gallons to seal the ornamental pond in the spring. Application with a paint roller on a pole is so very easy.

NOT SUITABLE IF SUBMERGED IN WATER!!! It dries a beautiful glossy black and stayed that way for about 2 days in my pond after I filled it. I let it dry for 3 days a month ago in AZ where the daily temps were between 82-96 degrees with no rain. After 2 days of filling it up, the entire Rubberseal product turned algae brown and now is permanently this color. There are some spots that had less than 1/4" thickness and the section below would never dry. You have to stab it and sometimes fill it with sand but still those areas are brown too. It's now been drained for 3 weeks and some of those spots simply will not dry and those spots are blistering as the heat increases to around 100+ degrees daily here.The other really big issue with this stuff is while it does have a hard feeling to the touch when dry, when submerged in water it softens up. So when you go to clean your pond, especially if you have to use a scoop to remove the last bits of water, you will tear this stuff. That's really bad because then the water can get underneath the coating and will destroy it from both sides. You could easily take a finger nail lightly to this stuff and you will scrape up goo rather than your finger nail drag across it like you'd expect with a hardened surface.$130 gone, the cleanup was not fun nor the effort applying it though the application effort is great overall, my pond is destroyed, I now have the worst cleanup job I could imagine next to shoveling feces for a living but at least feces aren't laden with chemical and feces can actually wash off. You need to use kerosene to get this off your skin and everywhere else you get it and you will get it everywhere if you don't lay down drop cloths. There's no such thing as a refund for a project like this so basically I took a gamble and lost everything I went in with and so much more.I'm confident this would be a wonderful roof patch or roof coating however even then it's black so that's generally not ideal unless say you're in the upper portions of the hemispheres.In the picture attached you can see what a coat after 1 week looks like at the bottom which is all cracked, and then the walls where I didn't do another coat and you can see it is exactly the opposite of what you'd want, algae and very rough brown.
