How to Fiberglass: Fixing a Cracked Kiteboard

Step 6 Cut the Fiber Glass and Mix More Resin

Once we figured out where we wanted the fiber glass to go, it was time to go cut out some pieces that we could use to lay down. We used woven glass mat, which means that the glass is woven with pieces of glass threads that are woven together like a textile. This type of fabric is stronger, but more expensive then chopped mat.

Rather then cutting the rectangular pieces out on those lines, cut across them at 45 degrees so that the fibers don't unravel. In other words, turn the the fiber glass so that you see lots of x's, rather then lots of +'s all over it. Then cut out your pattern as per usual.

The cuts don't need to be terribly precise in this step - it's all going to get sanded smooth so it's fine if the sheets have some rough or partially fraying edges.

Before continuing, it's best to make sure that everything is prepared and ready to go. The final part of this step is to mix the resin and once the hardener is added, the clock is ticking.

With everything ready, we mixed up a batch of epoxy laminating resin from System Three, but again, you could use any kind of laminating resin suitable for working with fiberglass in this step.
