How to Repair Your Inflatable Boat or SUP
Step-by-step guide to repairing punctures, valve issues, and seam damage on inflatable watercraft.
Small punctures (under 1/4") are repairable with the included patch kit. Clean the area, apply PVC adhesive, press the patch, and wait 24 hours. Valve leaks usually require O-ring replacement. Large tears or seam delamination need professional service.
The problem
Small punctures and valve issues are common but easy to fix. Without proper repair technique, users either overpay for professional service or make the damage worse.
The solution
Identify the damage type — puncture, valve leak, or seam issue — and apply the appropriate repair method. Most repairs take 30 minutes plus curing time.
Audience: Owners of inflatable SUPs, kayaks, and boats who want to handle basic repairs themselves.

Clean the area around the leak with isopropyl alcohol — at least 2 inches around the damage
- 4
Rough the surface with fine sandpaper for better adhesive bonding
- 5
Apply PVC adhesive to both the patch and the board surface

Wait 5 minutes for the adhesive to become tacky

Frequently asked questions
Can I repair a puncture on the water? ▼
Emergency repairs using a patch and tape can get you back to shore. Full repairs require dry conditions and 24-hour curing.
How do I fix a leaking valve? ▼
Remove the valve core with the included tool, check the O-ring for damage, replace if needed, and reinsert the core tightly.
What glue should I use for PVC repairs? ▼
Use PVC-specific adhesive like HH-66 or Clifton. Standard super glue does not bond well with inflatable PVC materials.
