About this item
Product details
Flex Seal is actually liquid rubber in a can! It sprays out as a thick liquid, seeps into cracks and holes and dries to a watertight, flexible, rubberized coating. Flex Seal coats, seals, protects and will stop leaks fast! Available in 12 vibrant colors. It’s like a…Handyman in a can!
Directions:
Read entire can. Wear face and eye protection, protective gloves, and clothing. Make sure the surface is clean, dry, and free of grease, oil, and dirt. Shake well. Spray 8” to 12” from surface, using an even, sweeping motion. Apply multiple, even coats until all cracks and holes have been filled.
Flex Tips:
Spray a larger area than area where the leak is and feather the edges. For best results, apply multiple coats rather than one thick coat and use at can temperatures above 60ºF. Make sure Flex Seal has filled all cracks and holes and is fully cured before testing product. If light can pass through, apply additional coats.

Professor
I had a problem with rotting around the base of the outside door surrounds. The moisture had rotted the wood, and I was going to have to replace the surrounds. I purchased the white flex paste and after digging the rotted wood out, I used the paste to rebuild the rotted area. It worked great. I have had no further rotting and the finish cannot be distinguish from the wood that was there. It was all white, so I didn't have to paint the flex paste. Great job!!
Hi there, thank you so much for sharing your Flex Success with us! We are so happy to hear the Flex Paste was the perfect solution for your door repair! We would love to see photos of the final results, when you have a moment, feel free to send some photos to Humans@FlexSealProducts.com. We look forward to hearing from you, Flex On!
