Flex Seal Liquid is a thick rubberized coating that you can brush, roll, dip, or pour to create a waterproof, flexible seal on nearly any surface. It starts as a liquid and dries to a strong, flexible, watertight barrier that stops leaks fast and protects against water damage, rust, and corrosion. Whether you're sealing a roof, repairing concrete, preventing basement seepage, or weatherizing outdoor structures, this versatile sealant works where traditional thin paints fall short.
Unlike standard paints, Flex Seal Liquid is super thick and creates a durable, breathable, weatherproof barrier that expands and contracts with the seasons. It resists rain, snow, sun, wind, hail, moisture, and UV degradation, remaining flexible even in extreme temperatures. The coating is mildew and chemical resistant, making it ideal for long-term outdoor protection.

Great stuff for just the right application.
This stuff is absolutely great for sealing all kinds of leaks on most surfaces. I've used it mostly roofing and flashing of various kinds, but I also stopped an aluminum boat from leaking around a seam two years ago, and it is still holding strong.
Flex Seal Liquid stops leaking from large pot.
sealed my 50 gal ceramic pot, base of which was cracked during a move.
