Amazing product that actually works!!
We have tried nearly every type of roof caulking out there. The Texas summers on a metal roof are brutal. This and the paint are the only thing that have held up. They flex and still seal where 2 pieces of metal contact where we have had a roof leak for years... no more leak. It set solid in 48 hours. Application was really easy and forgiving. We put on 3 layers of the paint on the tape just to be safe which surprisingly didn't take very much to do. No running or bubbling found. Even after 120 degree Texas days making the roof well over 150... and it still held. No cracking, running.. nothing. It is our go to now. Well worth the money and the only roof sealant that still seems to work. Mineral oil to clean the brush, easy to apply - just like a thick paint. Dries in 24-48 hours. 3 layers with the tape was enough to handle 7 inches of rain in 3 hours no leaks this spring. Thank you for making this and please keep selling it!

#1 Top Best Highest Quality Roof Sealer
The best ever roof sealer. Our commercial roof has leaked for 18 years.We tried 1 can and were very impressed with the thickness and adhesion.We have now ordered many cans of this and have 85 % finished patching our roof. Even so, after 3-4" of rain in the last 3 days, we are 100% bone dry with zero leaks.This stuff really works.

Easy to use and WORKS!!!
I used it to seal my roof, and after a few heavy rains, there’s no sign of leakage. What I love most is how well it holds up over time — no cracking or peeling. It’s an excellent solution for any waterproofing needs, and I highly recommend it for anyone tackling outdoor or home maintenance projects. Great value for the price!

Worked on my swamp cooler reservoir tray
My swamp cooler reservoir tray started leaking and I tried to use some of those spray on sealers and it didn't even last a full year. I bought this for the next year I followed the instructions to the letter, and I am going on 2 years and have not developed a leak. If I ever have to get a new swamp cooler (hope it will be now a long time thanks to this waterproof sealant) this will be one of the first things I will do the reservoir tray before using so it will last longer.

Use as directed
Works best in lower humidity and warmer temperatures. To cold or humid and it will cure slowly or not at all. As long as it is used as directed it makes a good rubberized skin that I plan to use again. I used it on only dry surfaces.

I wanted to start out by saying the company's customer service is amazing. There is a toll free number on the back of the bucket and someone answered my questions. We asked them about the dry time after 3 days of waiting for this stuff to get less sticky and they were very nice.We were painting this on a concrete/cement flooring. We live in FL and there is moisture in the soil. Our villa was built about 30 years ago and moisture was seeping up through the foundation. We had to rip out the flooring that was put down just 2 years ago (right before we moved in) because black mold was growing on the cork sub floor. (Not our choice to put down a cork sub floor on a foundation that had moisture but the previous owners clearly didn't know about the moisture issues).So, we starting rolling it in the main areas and painting it with a brush in the corners/sides. The stuff is very thick.However, a few days later it was still very tacky. Tacky to the point we couldn't walk on it. Every time we tried we would get stuck in place. It was pretty funny. We had tilers waiting for this stuff to "dry/cure" before the walked on it. I called the company on day 3 and they suggested to use talc powder or lay down plastic. Our tilers said plastic wasn't a good idea.On day 4 after we applied it they gave up trying to wait until it hardened and started laying tile. They said they ruined their knee pads and it was hard to walk on. We also noticed it was ripping. Wherever they would kneel, move tile, use their rolling cart, etc, it would leave holes. We had hundreds of holes throughout the waterproofing. I wanted to cry. It took us a while to apply and we lost time waiting for the stuff to dry (which it never did).We told them they would have to wait until we applied a second coat. We waited another 2 days and they came back. It did the same thing. Holes everywhere. We wasted about a week in time.Does it work? Maybe, but there is no way for us to tell since they laid thin set on top of it and it had so many holes. I cannot stress how shredded this sealant was. We wasted $150 and hours of time applying and waiting for it to dry. The tilers also were not thrilled with us at all.They told us to buy another product which the local Home Depot had. It is ever so slightly more but it was a dream to apply and, after days of tilers walking on it, hasn't made a single hole.I would not recommend this product to a single person. I wish we hadn't bought it. This would get negative stars if that was an option. I usually don't leave bad reviews but this was that horrible. Sorry Liquid Rubber.
