I haven't done this myself, but I would say it's too thick. The patches in the repair kit that came with my kite are much thinner than those used on bike tubes. Airborne sell the kits (saw them there on Saturday) and I'm sure all the other shops would have them too. Note that the repair "kit" is patches only. I bought a $2 bike tube repair kit from Bunnings yesterday for the glue and roughner, which I keep with my kite, and I put the patches from it with my bike stuff.

"Park Tools" brand is the manufacturer of all the patch kits sold with every brand of inflatable kite.
You should be able to get them at any decent bike shop for a few$$
They come in bigger sizes than what normally comes with a kite too.

For bigger splits tears and holes, you need a thermostatically controlled electric plastic bag heat sealer. With practice and good technique, it is possible to repair almost any bladder, regardless of the size of the hole.
I have repaired jagged splits over 300mm long. It is well worth the effort when you consider that an R4 18M bladder is $299!!!
Contact your local kite shop, see if they can do bladder repairs, even if you mail it and it takes week or so to be returned, it can save a kite that might not be worth spending $299 on?

Hi, I blew the end of my bladder and spent to many times trying to fix it. In the end i sent it to Moti Levy (advertises in kiteboarder magazine) I had it back within 3 days fixed for $bugger all. Understand that i sent it from Melbourne to tweed heads in three days. The guys a legend so top stuffing around and go kiting.

Some more info on bladder issues.

"Park Tools" bike tube patches can be bought at any decent bike shop, they sell for between $5 and $7 for the packs that come with kites.
Contraty to what I said in my earlier reply "Park Tools" does not sell the bigger patches in Oz - BUMMER. My son got some with a "Park Tools", bike mechanics tool kite he imported from the USA.

You should not use the sandaper or scratchers in common bike tube repair kits, to roughen up the bladder, this is only needed for bike tubes.

The best glue for larger holes is vinyl glue for repairing air matresses etc, get it from most camping goods stores, or flexible polyurethane glue, "Seam Seal" brand is excellent, I get it from Paddy Pallin and other similar stores.

If you get a blow out at the end of a strut or LE send it to Kitepower with a self addressed return post pack or envelope and there will be no charge - fixed for free.

All bigger holes need to be charged for but for example, to fix a split caused by the leading edge splitting in the middle the cost is usually around $30 - $40, which is a lot less than $299 for a North 18M LE Bladder (saved one this week the hole was approx 14 inches long!)

My early Wipika kites had more bladder problems than a bus full of pensioners on a winery tour!

An easier fix, than glue, is tape... but the stuff that comes in the repair kits isn't up to the job of big tears and I got sick of replacing it on small repairs; it doen't hold well enough and comes off after the kite has been packed a dozen times or so. So, better tape had to be found. McNett, makers of "Seam Grip", "Aquaseal" and other camping/hiking targeted adhesives, make a tape called "Tenacious"... and it is just that!

This stuff is the sh1t that doesn't come off the blanket! Be careful when you're placing it on the bladder; you wont get a second chance!!!

It is heavier than the tape that comes with most kites and a whole lot stickier... you may want to use some extra talc on the edges of the tape, once fixed to the bladder, to absorb the adhesive and ensure that it doesn't bind to the LE/rib cloth.

I bought some at "Rays Outdoors", should be available at other camping stores too, about $7.00 for 50cm x 7.5cm. It's pricey but cheaper than a new bladder.

If this reads like an advert for the stuff, cool, it's because I am really impressed with its' performance... inland kiting means rigging on grassed lake shores that seem to be always covered with thousands of sharp grass ends and thistle thorns... all I need now is an easier way of finding those tiny micro-holes that have stuffed more than the odd session.

There is some stuff that i use that is used for water tank liner repairs.. Comes with a tank.. Not sure who would retail it but it's strechy and sticky.. It can be used on the bladders or the canopy.. called Tear-Aid.. found their web site www.tear-aid.com/
I have only used the type A but it looks as though the Type B may be more suitable for bladders

bladders are made of TPU, a Polyurethane, not vinyl so "Type A" would be far more suitable... use Type B for cheap air-beds, old car seats and inflatable girlfriends (at least that's what I was told by an old stickboarder)

It is much more flexible than the "Tenacious" I mentioned above.

Anyone know of a local dealer that sells short lengths?
