Does Flex Seal expand as it dries?

Flex Seal is liquid rubber in a can that is easy to apply to surfaces to help coat, seal, and protect them. Flex Seal will not expand as it dries, so it’s important to make sure you apply it properly to ensure full coverage.

1. Spray 8-12 inches away from the application surface.
2. Flex Seal is best applied in thin, even layers. Use a smooth motion while applying, making sure to completely coat the desired areas.
3. Only apply one coat at a time. It’s best to allow Flex Seal to cure fully before adding additional coats.

Flexpert Tip: You can also spray Flex Seal directly into a bowl and paint, brush, or roll it on any area.
