Is Flex Glue waterproof?
Flex Glue is 100% waterproof. Whether you’re sealing a leak, bonding outdoor surfaces, or completing repairs in high-moisture environments, Flex Glue is built to last.
Waterproof vs. Water-Resistant
Many adhesives are only water-resistant, meaning they can tolerate light moisture but will eventually weaken. Flex Glue goes a step further—once fully cured, it forms a watertight seal that won’t crack, shrink, or peel under wet conditions.
Can You Use It in Wet Conditions?
Yes! Flex Glue can even be applied to:
- Wet surfaces
- Damp environments
- Underwater surfaces (for emergency repairs or temporary fixes)
Flexpert Tip: For the strongest bond, it’s best to apply Flex Glue to clean, dry surfaces when possible. If applied wet, allow extra time for the product to fully cure.
Ideal Waterproof Applications
- Bathroom repairs (tile, tubs, sinks)
- Outdoor bonding (gutters, downspouts, vents)
- Pool and spa areas
- Boats, RVs, and marine projects
- Sealing seams and cracks exposed to rain
Once Flex Glue cures, it stays put—even when submerged. That’s why it’s a favorite for DIYers, contractors, and weekend warriors alike.
