The glue we use is an industrial strength hot melt glue but the standard stuff you can get from a hardware store does the job. We've got heaps of spare glue that is supplied in small chips. Shoot me a PM if you want some to re-glue a Ke Nalu paddle and we can post it to you.
A few tips to help get a good bond and a nice clean finish:
- watch the assembly vid

- wrap both components with electrical tape so that excess glue doesn't make a mess when joint is pressed together.
- make sure both components are well heated but be careful to not cook it! Keep the heat source moving. Glue should be like thick honey when it's sufficiently heated.
- insert the blade / handle into the shaft with a screwing motion, in and out several times to work the glue into the joint.
- I use a wet finger to wipe the excess glue flat onto the electrical tape while it is still hot. Be careful though cause it'll burn if you don't keep your finger wet.
- remove the electrical tape and most of the excess glue while the glue is still hot. This will leave about a 2mm wide, tidy bead of glue around the joint.
- reheat the remaining bead of glue and flatten it across the joint with a wet finger.
- while glue is still hot and soft apply a couple of wraps of electrical tape over the glue / joint. The hot glue melts the glue on the electrical tape and it kind of acts like shrink wrap.
It sounds like a bit of a process but it's very easy and only takes a couple of minutes.
Another tip.....don't leave your paddle out to bake in the hot sun! It can get hot enough to soften the glue.
Happy paddling!!
