Do You Stir Flex Seal Liquid?
Most paints and coatings need to be stirred before use, but Flex Seal Liquid is ready to use right away—no stirring necessary. This liquid rubber sealant is carefully formulated to maintain the right consistency straight from the can.
Why You Shouldn’t Stir Flex Seal Liquid
Stirring Flex Seal Liquid can introduce air bubbles into the formula, which may affect the smoothness of your finish or interfere with curing.
Tips for Using Flex Seal Liquid
- If there’s minor separation on the surface after long storage, gently rock or tip the container side to side before opening to redistribute the formula.
- Use a clean stir stick only to check consistency, not to mix it aggressively.
- Always check the expiration date on older containers. If the product has thickened significantly over time, it may be past its optimal use window.
Flexpert Tip: If you're working in colder conditions and Flex Seal Liquid feels thicker than expected, let it sit at room temperature (60°F–90°F) before applying. This helps restore ideal viscosity without altering the product by stirring or shaking.
