Liquid Rubber L R Waterproof Sealant (Original Black,1 Gallon)

Very good, but overpriced with shipping etc!

It kept out the rain

Perfect for my Needs!

It is a relatively convenient waterproofing system, which stops water penetration dead. Painting it on can be messy. We found you really need turps [mineral turpentine] to clean up brushes and spills even though it claims to be water-based. Don't use your best paintbrush for this material - once used for this you wouldn't be able to use the paintbrush for regular painting jobs after. It dried within a day (strong sunshine, 30-35 degrees C/85+ Fahrenheit). I reckon at a more civilised temperature, it would take 2 days. It works well when you've got good access, provided you clean the surface, but there were a couple of situations where access was very tight and we couldn't clean/prepare the surface properly. This sealant has high viscosity, meaning it doesn't stick onto the surface if it's dusty or when we're poking the paintbrush in at a funny angle. It's not proper procedure, but we thinned it down about 50% with turps to overcome these problems, to get the first coat on. Second coat was then easier.

Really good stuff for cheap roof repair. I’d probably only use it as a temporary solution however as it does seem to degrade after a few years

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.
