Many first time boatbuilders use more epoxy than is required. Epoxy is both expensive and heavy, so here are some tips to help you use less epoxy, spend less money, and build a lighter boat:
- Apply thin coats of epoxy on flat surfaces with a short nap yellow foam roller. This will help prevent runs and sags. Not only will you save epoxy, but you'll also save a lot of sanding.
- Once the weave of 'glass cloth is full or almost full, don't apply more epoxy. It will add little or no strength, just extra weight.
- Plan your epoxy use. If you're gluing several small parts, have them all lined up and ready before mixing the epoxy so it won't cure in the cup while you're preparing the next part.
- Use enough epoxy in joints, but not too much. When you clamp a joint, a little epoxy should squeeze out. But epoxy running and dripping out of the joint is wasted.
