  • Saved me!!!!
Size: 1 Gallon Color: Original Black
I was able to apply this to my metal roof of my old build and business, after a very harsh heavy snow winter then heavy rain with multiple leaks FIXED ! It’s the easiest thing I have done to repair my roof the expense of this is nothing compared to what would’ve happened if I wouldn’t have applied it! It will 100% be part of my maintenance for my building for years to come. Buy it you can’t go wrong! ... show more

  • Very Nice
Size: 1 Gallon Color: Original Black
Less expensive than the leading brand and works very well. Used it to coat bottom of a raised indoor garden bed, and worked like a champ. Bit of a strong smell after use - but wears off in time. Would repurchase again

  • Used on “newer” metal roof dormer and chimneys
Size: 1 Gallon Color: Original Black
I’ve had leak issues with my metal roof from the time it was installed, primarily around the dormer, and of course the chimneys . I applied two coats, product covers well, and goes a long distance…a gallon goes a long ways. So far it’s worked, I want to see how it performs in neg temps though. In VA we’ve had several below freezing nights and the product is def better than the old tar, multiple caulking and other products on the dormer. Seems to work great on chimneys too so far. ... show more

  • Saved my spa cover
Size: 1 Gallon Color: Original Black
I have a vinyl spa cover that was starting to leak and get waterlogged just from normal rain. The vinyl just had dried out over several years and become porous in spots. Getting a new cover would be at least $400 so I decided to try painting with liquid rubber instead. After a good cleaning, It took about half a gallon to put 3 coats on my approx 49 sq ft spa cover. I painted the seams with a brush and then rolled the larger open areas. The product applied easily and seems to adhere very well.grey color was perfect in my case. It looks like a new cover and is no longer leaking. Too early to say how it will hold up but so far so good. I’ve also found other uses for the product, such as encapsulating stubborn stains on interior painted ceilings, basically using the liquid rubber as a sealer before applying a coat of latex paint. ... show more
