Flex Seal MAX Liquid Rubber Sealant Coating, 2.5 Gallon, White

Why i chose this, because it works. If you read or research the manufactures preparations prior to applying, you will find that "It Works". Really, the temperature range is between ( -80° ~ 350° ) , wow ! Only thing I did not care for was the smell at first. The off gas is bad. Always use your ppe respirator. In a few hours it dissipates and the smell is much weaker.

I used Flex Seal liquid rubber on a hairline crack on outer basement wall, application went on easy, used two coats...I feel very confident this will solve my problem. I researched many different products and I believe this is the Best product for my problem...Lord willing I'll have no more leaks!

I applied Flex Seal Liquid MAX to the roof of a 1999 RV. I was truly impressed at how well it covered the surface with very little prep. I trimmed the edges and roof features with a brush and used a roller to apply to the large flat areas. I highly recommend this product and plan to use it for more applications.

We had some water coming in our basement through a concrete wall. We painted the entire wall with flex seal and it sealed the deal. It really works and is easy to use. We have used this product before and it does the job...it works exactly like they say...you will not be disappointed.

The clear coat went on easily and sealed up the seams in my basement cinderblock wall, keeping out rainwater. The Flex Seal couldn't be cleaned from my brush, so I switched to cheap throw-away brushes. During painting and curing, Flex Seal had a very strong odor which permeated the entire house and took 2 days to disperse, even with open windows in the work area and vent fans going full blast. The dried coat is glossy, which makes the painted area reflective and look wet; a flat finish would be much better and non-glare. The Flex Seal liquid did not require mixing, just open the can and apply.

Flex seal i am realizing is not meant to roll on as a rubber sealant. Because of how thick it is,.i was only able to cover 1/3 of my EPDM 14'X66' mobile home roof. It was extremely difficult to roll on. Several days went by and i went up the ladder to check the Flex Seal on the roof. I noticed that %231. It took forever for the morning dew to dry off where the Flex seal was. Also, everything sticks to the Flex seal is. It bothered me so much that i got a diff rubber roof sealant from Home Depot and rolled that over the Flex seal! Flex seal really should only be used as a patching sealant like your silicone caulking.

it was to liqui i put it up. but its on a virticle surfice so its sagging, cold outside so not drying, but this pring ill tear it all out and fix what is damaged... the flex tape, just failed. its not sticky, in wet surface like you advertise, it dont work. i am very dissapointed. i will still buy things but vary little now.

It didn't stop our patio from leaking into the garage. :( We added another coat and it still didn't stop, but slowed it. I expected it to act like it does in the commercials. It didn't. We couldn't find the 2.5 in grey anywhere. But we did find 4 gallons. But it didn't cover as much as the can said. So, where it had some good it had more bad. I'm was very disappointed to spend the money on it and it didn't stop the leak.

the sealt was hard to use. was really thick, hard to spread on the wall. i thought it was better then what i got. what a waste of my money and time.
