How To Repair A Kite Bladder:
Kite bladders can easily be repaired with just a clothes iron. For large rips, you will also need some old bladder material for a patch. Below is a picture of a ripped bladder.
Cut off any damaged bladder material, mark the patch area with a felt marker pen. I have cut out a bladder patch (from an old bladder) that is larger than the hole.
Glue To Fix Your Kite Bladder
Now for a special tool, I glued cloth around the wood dowel. I made several lengths of these, but you could actually just use a pencil or something and lay the cloth over it. Put this inside the bladder under where you want the patch to be seamed. Then lay the patch on top of the hole.
Set your iron to a low temperature, I use a setting just below steam on a steam iron. Use a layer of paper to protect the bladder. Parchment baking paper is ideal but any thin paper works.
Press firmly and iron holding the iron on each part of the seam for maybe 1 second. (Never let the iron touch bladder material directly or you will melt it.) This should melt the patch and bladder together in a seam.
What About Kite Valve Repair Taping?
Now I use another shorter short cloth-covered dowel under where I will seam the next side of the patch. I will cover it with paper and iron it.
I move the dowel to the end of the bladder, cut the tip off, and remove the dowel.
Kite Repair Kit And Tools
So here are the tools that were used: scissors, clothes iron, felt pen, cloth cover wood stick, parchment paper, and a spray bottle of soapy water. The impulse bag sealer is handy for some seams but is not really necessary. You can buy an impulse bag sealer on Amazon for near to nothing. You can buy parchment paper at a grocery store in the baking section.
