A Look at the Flex Seal Lineup

- Concrete and foundation repair
- Basement waterproofing
- Roof, gutter, and pool maintenance
- RV and motorhome weatherizing
- Available in black, white, clear, and grey.
Flex Seal Spray
The product that started it all — “liquid rubber in a can.” This aerosol sealant sprays on as a liquid and dries to a durable, rubberized coating that flexes with temperature and surface changes.
Ideal for:
- Roof and gutter leaks
- Auto, boat, and RV repairs
- Weatherproofing around windows and foundations
- Indoor and outdoor sealing jobs

Flood Protection Tape
Engineered for critical sealing applications, Flex Seal Flood Protection Tape instantly bonds to smooth, flat, nonporous surfaces to help keep water out. This extra-wide waterproof tape adheres securely to both horizontal and vertical areas, making it ideal for sealing wide openings.
