It’s liquid rubber in a can! Brush it, roll it, dip it, pour it!
FLEX SEAL® LIQUID
FLEX SEAL® LIQUID is actually liquid rubberized coating in a can! Similar to our Flex Seal® Spray, but now you can brush it, roll it, dip it or pour it anywhere you need a watertight, flexible coating or sealant. Our patent pending, proprietary formulation starts out as a thick liquid and dries to a super strong and flexible, watertight, rubberized coating that protects and helps stop leaks fast.
- Forms a durable, breathable, weatherproof, non-slip barrier
- Resistant to rain, snow, sun, wind, hail, air, moisture, UV degradation, extreme temperatures and natural weathering
- Blocks out air, water, and moisture
- Prevents rust and corrosion
- Mildew and chemical resistant
- Safe around plants and animals*
*When Flex Seal® Liquid is in a fully cured and dried state.

Tips for Brushing/Rolling Applications
- Brush or roll Flex Seal® Liquid using an even sweeping motion.
- Apply several even coats until the surface has been completely covered and ALL cracks and holes have been filled.
- Always brush or roll over a larger area than just where the leak occurred.
Tips for Dipping Applications
- Dip object into Flex Seal® Liquid, making a slight swirling motion.
- Once you feel the surface has been fully coated, remove and let any excess liquid drip back into the can.
- Hang or clip object in the same vertical position as it came out of the can and let dry.
- Once fully cured, you will have a super strong, no slip, rubberized coating on the surface.
Tips for Pouring Applications
- Pour Flex Seal® Liquid directly on the surface, allowing gravity to take the liquid into cracks, holes, and/or other hard-to-reach areas.
- Continue to pour until the surface has been covered and all cracks and/or holes have been filled completely.
- Allow at least 48 hours for liquid to fully cure.
