Instructions for Repairing Inflatable Kayaks

Most inflatable kayaks come equipped with a repair kit that includes adhesive and several patches. These can also be purchased at major sporting goods stores. 

Repairing Small Punctures and Cuts

Making repairs to the inner tube may require unzipping a cover and temporarily removing the tube. Always make certain the boat is fully deflated before unzipping or removing the cover. Then, when the boat has been repaired, make sure the tube is aligned properly in the boat cover and the zipper (if present) is completely closed.

1. Cut a patch which is round or with round corners, at least 1/2  (12.7mm) larger than the hole or cut.
2. Use water and/or mild soap to clean the area where the patch will be placed.
3. Make sure all surfaces are dry.
4. In a well-ventilated area, spread a thin layer of glue on both thepatch and on the damaged area, and let it sit for 3-5 minutes or until tacky.
5. Press the patch onto the boat, making sure no air bubbles form.
6. Apply pressure to the patch by placing weight on it. Do not peel back to see if adhesive is holding.
7. Do not inflate the boat for at least 12 hours.

Repairing Pinholes

1. Inflate the kayak. Locate the pinhole by sponging soapy water over the tube until you see air bubbles. Mark the location.
2. Deflate the kayak. Clean the area around the pinhole and apply a drop of adhesive to the hole once the area is completely dry. A patch may not be necessary.

Seam Openings

Seam openings are more difficult to repair, but can be done with certain repair adhesives usually found in local marine shops.

Slow Leak

It is possible that the valve gaskets are not properly tightened, or cross-threaded. Remove the valves and replace carefully, hand tighening. Make sure the cap tether is not interfering with the seal. The valve gaskets must be closed tightly. If a slow leak still continues, swap the valves to see if that is causing the problem.
