Flex Seal Liquid Rubber in a Can, 32-oz, Gray

works as advertised. easy to apply, little on the expensive side.

liked it because it self levelled and easy to use .l dislike the time it takes to dry

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.

I love flexseal!! Some people don't, and they are wrong. I held a concrete pool edge together for years with this stuff. Concrete was coming off in chunks, I flexsealed those babies back in place, coated the area, and it was fine for years. This can was used to seal a messed-up ditch dug across my asphalt driveway. "How do you mess up a ditch??" you ask. Well, my guy managed. I had to have another guy jackhammer part of it back out, then I coated the whole thing with flexseal. I expect it to last years, and if it starts to come apart, I'll put more on.

Size about a quart purchased, only needed to cover a 2'x4' area. Applied it by brushing and pouring on, not easy to brush, a roller was out of the question so mostly poured and spread with the brush. It took the entire can to cover the 2'x4' area, but I did put it on thick, not like I had a choice though. It sort of self levelled which was good and it appears to seal up the area pretty good. I put it on a pt plywood roof for my water filter. It actually looks really good and like it will do the job, it's been a couple days so it is drying nicely, the next rain will be the test. Bottom line, it doesn't go very far so if your covering a larger area buy more than you think you need, and I can't see adding a second coat because it goes on so thick to begin with a second coat would seem to be a waste and overkill.
