Two layers of cloth would be good or? On top and bottom? Would it be better to laminate these layers separately ore together?
How much glass you would prefer for bottom and top? Isnt it a good idea to meassure the original layers? We are talking about a kitesurfboard you know!
The board over all is very very light....so no problem with the weight but i want to keep the flex because i dont want to make it much harder.
Maybe its better to peel of some glas before laminating... i dont know.....there is a bambo layer under the glas on top.
Here’s the point; An EPS core with layers of Fiberglass only will snap easily. So if you are going to by a board of this type you should research the construction of such a board. Also the longer a board of this construction the more likely it will snap. An EPS core with Epoxy Resin and Fiberglass Cloth with no reinforcement internally will snap. The Bonga Perkins Boardworks Model was one of the nicest shapes I’ve ever seen, but of all the ones I’ve seen on Maui none of them stayed together long enough to even take a template off.
It's a kiteboard? Good luck keeping it in one piece, unless you add some good reinforcement in the repair.
Given the kind of stress those things endure, I'd say that once you snap it, just toss it.
“That which can be asserted without evidence, can be dismissed without evidence.”
What would be a good reinforcement for the core?
Paint sticks. Gallon or Five gal. Size cut to six or eight inches. Otherwise if you can cut some strips of 1/4 or 1/2” high density foam or PVC “Sign Board”. Either one of those will work as well. I’ve always used paint sticks. If you look at them in a paint store or Home Depot; you’ll see that most of the time they are Basswood. Inserted to a depth below the surface across the snap, you can use a filler like Q-cell and opaque resin/cloth. On a Thai or Chinese board that is already white opaque, the repair will disappear. Keep in mind that a lot of the Asian boards are painted and then clear coated. If the board is clear, that’s a different situation. I couldn’t tell from your pics.
