Review: Tough, Reliable sealant - If you want a sealant that can handle high water temperature and last the test of time, you found it. I used this to seal my homemade solar water heater tank back in early 2022. Today it still hasn't leaked although the tank has reached 130 degrees in summer. Four years of abuse and still reliable is a solid proof of its quality.
Review: Worked for Me but one minor complaint - I did give it a 5 despite one issue- The positive first - Had a leaky flat roof (slightly racked) over my garage - Was going to have it done professionally for over $5000 ish. To replace the existing membrane. Well Liquid Rubber has a help line email so I asked them if this product would work well - and gave them details of my roof etc. - I got an immediate response and then ordered 10 gallons, based on the surface area etc. This was my bad - but to do I believe the recommended 5 coats it took about 6 gallons - since this stuff is bit pricey I could have ordered 5 gallons and 1 gallon and saved $. Good news is the roof did not leak anymore, and looked good. Here was the complaint- I had left a black rubber garden hose on top of the garage months after applying the sealant- maybe it was up there in the middle of August for 3 weeks- Well when I went to remove the hose it was stuck to the roof - It was not that hard to pry it away but it actually left kind of a stain on the roof. So my bad for leaving the hose there but I did not expect that. I have to check but I will have to do this again at some point-

### ⭐⭐⭐⭐⭐ High quality and price point.
*by R***E on October 11, 2025*

The odor is low, it applies easily with a brush, and builds up well making a nice waterproofing on wood, synthetic decking, and metal roof. Dries quickly. It's expensive but it works.
