Tips for Using Flex Seal White


Before applying Flex Seal White Sealant, ensure that the surface is clean, dry, and free from any grease, oil, or dust. This will ensure optimal bonding and create a lasting seal.

Protective Gear

To protect yourself during application, wear gloves and safety glasses to prevent potential skin or eye irritation. Additionally, consider wearing a mask to avoid inhaling any fumes.


After each use, ensure that the can of Flex Seal White Sealant is tightly sealed to prevent the product from drying out. Store it in a cool, dry place, away from direct sunlight or extreme temperatures.
