Duracell project: Protecting epoxy resin from UV rays

Aug 26, 2023

Between lengthening the hull of his 60-foot Duracell, creating a swim platform, new coamings and new cockpit benches, Matt spent many hours working on the Duracell aft area, and added a multitude of small parts. Busy working on various projects, he didn't always finalize all the laminations needed to assemble the boat. But since Duracell is stored outside, and the structure protecting it doesn't extend all the way to the transom, the area is exposed to the sun's UV rays. These are not good for the epoxy resin in the long term, and require a layer of protection. So Matt set about laminating all the corners and exposed foam parts.

Once all the exposed areas have been covered with fiber, Matt can tackle the sanding, which is necessary before any paint application. To make sure he doesn't attack the structural layers, Matt has added thin layers of fiberglass in some places.

Finally, it's time to paint. He applies 2 different types of primer. The first, covering the trunk bottoms, is a specific primer for bilges. Outside, he then applies a white primer to all surfaces, the advantage of which is that it remains "open" for 6 months. Matt then has 6 months to apply a second coat, if he wishes, without sanding first.

Monochrome, the Duracell cockpit begins to reveal its true face, and Matt and his friends can enjoy a meal in it!
