Review: Decent product, as good as seen on TV. - Bought for waterproofing layer on a garden waterfall feature on top of the liner. Have tried several of the other flex seal products, the spray was quick and easy, the caulk worked decently as well for making a fillet and sealing cracks, but this? This was awesome, would definitely recommend in my situation. Brushed on with a 2 inch brush, layed out flat as it dried. Great build up, and one coat is really all it needed. If you're sealing a water feature, or basin for outdoor use, this works good. Just let it cure before you let any livestock/animals near it just to avoid making them sick.
Review: Amazing Product Seals Like Crazy - I had a problem with water seeping from my deck into the bedroom below. Every time a storm approached, I had to lay down plastic sheeting and hope for the best. Once I discovered Flex Seal, however, I stopped worrying. I reapply a coat every couple of years, and the sealant holds up perfectly. I even used it to fill in some wooden planks experiencing dry rot, and it seems to have halted the decay of the planks. This is just in my experience; I can't attest to this being an approved use of the prouct.
