  • Added bkackfirst. Coated with gray as back up then finished with clear. To spot any leak at that drain pipe joint. Working great.

Flex Seal Liquid - pint

a year ago
Product works, but despite my securely closing the lid between usage, a portion of the remaining contents start to solidify, requiring removal of that portion to get to useable material.

Yes, I recommend this product.

Looks Like it Will do the Job

a year ago
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.

Yes, I recommend this product.
