Raft Repairs

Commercial Grade Whitewater Rafts

Aquaseal Urethane Repair Adhesive can often create an emergency patch on pinhole air leaks in whitewater river rafts (such as those made with Hypalon®). To apply, deflate the raft and buff the area lightly with sandpaper. Then wipe the area clean with solvent (such as acetone or toluene) and allow to dry before applying the Aquaseal. Allow the Aquaseal to dry level overnight (or use McNett Cotol 240 to accelerate cure time to 2 hours) before re-inflating the raft. For more permanent or elaborate repairs (and all seam repairs) consult your raft manufacturer.

Inflatable Kayaks

There are two types, those with interior air bladders that are separate from the external fabric ‘skin’ and those where the ‘skin’ and bladder are a single welded unit. For those with separate bladders use the McNett Inflatable Patch Kit to patch the bladder alone. For those without a separate bladder use Aquaseal on the exterior. Simply clean the area with soap and water, rinse well, air dry, then apply Aquaseal to the damaged area. Note - Always patch deflated boats.

Recreational Rafts and Pool Floats

Inexpensive rafts and pool floats made of PVC can be difficult (and are sometimes impossible) to patch permanently. Aquaseal can often create a temporary patch. To apply buff damaged area VERY LIGHTLY with sandpaper then wipe clean with solvent (such isopropyl alcohol or stronger solvent) and allow to dry. Apply Aquaseal to pinhole and 1/2 inch (2 cm) beyond in all directions. Allow Aquaseal to dry level overnight then apply a McNett I-Patch (from the McNett Inflatable Repair Kit) before re-inflating the raft. For more permanent repairs (and all seam repairs) consult the raft manufacturer.


Paddlesports Tip

Kayak cockpits are notorious for cutting into spray skirts and causing exterior cracking. Apply spot applications of Aquaseal to permanently repair and protect both the interior and exterior.

Rope Storage Tip

Keep knots and kinks from jamming in your throw bag by stuffing it correctly! 
Step 1. Untangle and spread out your rope on a clean surface.
Step 2. Turn your back to your rope, drape it over your shoulder and begin to coil it into your throw bag.
Step 3. Ensure you’re stuffing the bag evenly and that kinks are untwisting behind you.


Keep Your PFD's Looking New

Protect Your PFD's & Accessories

Don’t forget to treat your PFD’s! UV Tech slows color fading and protects all types of paddling accessories from sun damage.

UV Tech™ Protectant

How UV Tech™ Works

Materials like Hypalon®, PVC, fiberglass, roto-molded plastic, and other materials are damaged, bleached and ultimately destroyed through use and by sun exposure. UV Tech protects and rejuvenates surfaces, reducing cracking, helping to block sun damage and restoring your boat’s original good looks.

Protect & Restore Your Boat

Every 30-45 days of sun exposure treat surfaces of boats, PFD’s, spray skirts, paddles, and dry suit gaskets with UV Tech™ Surface Protectant & Rejuvenator to protect surfaces, enhancing color and minimizing the appearance of scratches.

Protect Your Equipment


When in doubt, use UV Tech – it is environmentally friendly!
Many manufacturers recommend against the use of silicone protectants because: 1) Silicone is not compatible with some of today’s materials; and 2) Silicone is slippery and can prevent adhesives from bonding – making repairs more difficult.
