Being using flex seal for 4 years used it when I installed new roofing. Now using it for fence poles. Works great

This stuff has provided a 'final solution' for certain outside wood on my home. I live where the seasonal temperature range can be 100F to -40F. This is brutal on even the best, long-lasting outdoor house paint. Every few years I would have to scrape and/or sand cracked or peeling spots and do touch up. Since I first used Flex Seal on critical places (like window frame tops where snow and water sit), I have had NO FURTHER MAINTENANCE.Note that there is conflicting information as to whether you can apply regular paint on top of the Flex Seal (for me, I wanted to knock down the Flex Seal's high gloss finish). So, last year, I painted over some trim that had been painted previously with Flex Seal to test adhesion and durability. All I did to prep the Flex Sealed surface before applying regular house paint was to scrub with a TSP solution. So far, no peeling or cracking has occurred.The only negative I have observed is that the Flex Sealed surfaces attract dust noticeably, almost like it's statically charged. However, the surface cleans up easily with a hose and soft-bristled brush.This stuff yields a truly waterproof barrier that has eliminated the periodic painting I had to do every 2-3 years. The wood trim is sealed and no shrinkage or cracking has occurred. I'm getting older, so the less time I spend on a ladder is fine with me!

Terribly expensive and a workout to brush on to a large surface. Verticle surfaces require very thin coats or it will run. That being said I am pleased with the results. I used multiple layers on the roof of a cargo trailer that I built a cover for out of plywood. I use the trailer for fall hunting trips and have had problems with minor water leaks in the past. After using the Flex seal I have what I believe will be a completely waterproof roof and should stay dry this year and in the future. Would give it 5 stars if the price was more affordable !

pours smooth,seals great. I hope it last longer than other things I have tried

I purchased this for my Son and he is very pleased with the application a durability of Flex Seal Liquid. Instead of spending $1000 on Rhino Lining his truck again, he used Flex Seal Liquid. He rolled his entire truck bed with it. He put 4 coats on his Chevy Silverado with an 8ft bed. He used 1 and 3/4 gallons to complete the job. It is thick and can handle the hard knocks. The look of it is actually more attractive than Rhino Lining. Update: I also used Flex Seal to repair the interior of my Honda Accord. There are plastic parts inside the car that have deteriorated over time from the heat and sun in Florida. The plastic became tacky and was coming off onto everything that touched it. My hands were constantly getting sticky and it actually ruined a few pieces of my clothing. I taped up the areas surrounding that plastic and applied Flex Seal. It became hard over night and and now those parts actually look better now than they did when the car came from the factory. I must add that the quality of the liquid Flex Seal seems to produce much better results than the spray. I've used the spray on a few items around the house and it does not apply as evenly as they liquid and is no where near as durable as the liquid. This product is absolutely fantastic! There is no doubt in my mind that boat cut in half in the commercial was indeed repaired with Flex Seal. It is the real deal!

When I told our wife I wanted our house to be “incompetent handy-man chic” she had know idea what I was talking about. But, thanks to FlexSeal, our house looks like someone tried to make minor repairs with a can of over-priced black paint, and regular paint probably would have done a better job.Flexseals amazing properties means it won’t fill in ANY crack on any surface. As soon as you brush or roll over the surface to smooth it out, the sticky, foul smelling goop will be pulled out the crack. And I know what you thinking, that’s just on vertical surfaces, but you’re wrong! Got a crack in your driveway and would rather repave? Well now you can choose between speed bumps of black paint or black panit on ether side of the crack. It’s like Bob Ross always said, you’ll be in agony city.But wait, there’s more. If you act now you’ll get the regret of having spent money on this crap and, if you’re brave enough to use, it the shame of what you’ve done to probably a decent home. Your neighbors will wonder what the hell you were thinking.Seriously though, I have regretted a purchase this much since I took a grad school class with Michelynn McKnight,, and that decision helped make me into the alcoholic misanthrope I am today.

I brushed this on a custom canvas top I made for my 1960’s military truck. Works amazing. I have used it in the past for sealing metal shipping containers and semi trailer roofs. Great stuff!

I used this to fill cracks in my asphalt driveway previously. It’s expensive but lasted a few years so when more cracks appeared I bought more and filled the new cracks. If the cracks run deep I backfill with sand and pour the Flexseal over the top. It lays out flat on its own and dries within 24 hours in summertime temps.
