Which Glue Should I Use To Repair My Inflatable SUP?

Inflatable stand up paddle boards (iSUPs) are built tough, but like any inflatable product, they can occasionally develop small leaks, punctures, or seam issues. When that happens, the right repair materials are essential to keep your board watertight and reliable on the water.

Most new inflatable SUPs include a basic repair kit with PVC patches and glue, but due to recent hazmat shipping restrictions, many boards no longer come with adhesive in the box. If your repair kit did not include glue—or you’ve run out—it’s important to know which products are best for repairing your board.

Below, we’ll cover the most trusted adhesives used by paddlers and repair professionals, along with links to purchase them.

Why the Right Glue Matters

Not all glues are created equal. Inflatable SUPs are typically constructed from PVC or TPU materials, and only certain adhesives can properly bond to these fabrics. Using the wrong glue could mean a weak repair that doesn’t hold under pressure, leaving you with a slow leak or another failure down the road.

When repairing an inflatable SUP, you want a flexible, waterproof adhesive that can bond securely to PVC, resist peeling, and handle the stresses of inflation, deflation, and paddling. The following adhesives have proven themselves in the SUP, inflatable boat, and whitewater rafting industries.

Recommended Glues for Inflatable SUP Repairs

Clifton Urethane Adhesive

Clifton adhesives are well-regarded in the whitewater and rafting community for their strength and flexibility. This urethane-based adhesive works well with PVC and provides a durable repair that can handle high air pressures. Clifton is often chosen for more permanent repairs or when patching seams under stress.

AquaSeal FD Flexible Repair Adhesive

Purchase AquaSeal Here

While AquaSeal isn’t a traditional PVC cement, it’s a versatile repair adhesive that can seal small pinholes, tears, or leaks. It dries into a flexible, rubber-like consistency that remains waterproof and durable. AquaSeal is a good backup option if you’re on the go and need something reliable in your repair kit.

Final Tips for SUP Repairs

Clean the area before applying adhesive—use isopropyl alcohol or a mild cleaner to remove dirt, oils, and debris.
Roughen the surface slightly with fine sandpaper for better adhesion.
Apply pressure while curing—use a roller or flat object to press the patch firmly.
Allow full cure time (usually 12–24 hours) before inflating and paddling.

Conclusion

If your inflatable SUP kit didn’t come with glue, don’t worry—you can still find reliable adhesives to make strong, lasting repairs. HH-66, Stabond, Clifton, and AquaSeal are all trusted products that paddlers around the world use to keep their boards on the water. By choosing the right adhesive and following proper repair techniques, you’ll be back to paddling in no time.
