- Make sure the surface is clean, dry and free of grease, oil and dirt.

- You can either brush, roll, dip or pour Flex Seal Liquid directly onto surface.
- Allow each coat to dry completely (24 to 48 hours) before adding additional coats.
- Flex Seal Liquid fully cures in 48 hours.
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.
- When pouring Flex Seal Liquid into an area of depth greater than ¼ inch, allow each ¼ inch layer to cure completely before pouring the next layer.
- Allow at least 48 hours for liquid to fully cure.
WARNING: Avoid contact with eyes and skin. Gloves and safety glasses are recommended. KEEP OUT OF REACH OF CHILDREN.
