So you want to coat ur sweet kite, here is how you do it...
Mix pure, new silicon sealant with turps/white spirit/mineral spirit (oudorless if possible). MIX thorughly then put into a clear water bottle and shake until the silicon is FULLY suspended, no lumps.
Apply two coats to the extrados 1st coat 5:1, then, leave overnight and then 2nd coat, 3:1 (3 parts white spirit,1 part silicon sealant). Be aware that the first coat will soak through and you dont want a slippery floor
. The turps evaporates fairly quickly the fully silicon cures up to 24hrs later
The extrodos (outer surface) takes all the wear as its pumped up, deflated, and packed away on the sand (or whatever). Also the extrados takes the main UV hit. Best to start treating the kite in the first year. Im hoping that one treatment will last the life of the kite as silicon doesnt not break down. We will see!
It can be applied applied a broad brush and cereal bowl. Kite must be dried flat.
The kite weight will increase by the about the weight of the silicon chaulk, but the canopy will not hold water as it is hopefully non-porous. The kite MAY still be lighter than original weight.Tear strengh improves, hang time inproves, wear is reduced.
For the LE you may wish to try the window film, for areas that touch the sand (not tried) or car wax wipes. If the LE bladder is out u can coat the whole kite in one go (u dont want to unglue valves, or contaminate the bladder). Ive never had a strut blow out, so why add to the weight.
I live in thailand, UV damage is a bitch. Everytime u use the kite it gets lighter. Prevention is better than cure (and MUCH cheaper).
c u on the water..
PS..Hey, let me know how u get on!
