With the stack of mahogany wall panels finally painted with eight coats of ICA base clear then topped with two coats of semi-matte, the next step involves insulating the back-side of each panel. The hull, decks, and cabin top are already insulated with spray foam, but I’m also using Buffalo Batts to insulate the back of each wall panel that faces the hull to make the boat more comfortable all year-round. Insulating each panel adds a lot of time to the process, but I think it’ll be worth it.
The epoxy serves two purposes: it seals the panel, giving it stability over time, and it acts like contact cement to hold the insulation in place and tight to the panel. I kept the epoxy away from the areas where the panel will contact the mahogany cleats that are attached to the aluminum ribs. I’ll wet that out and edge seal the panel, then apply wood flour-thickened epoxy when I bond it in place.
That’s it for the insulating. Now for the fun part!
