Interior Substrate Final Fairing

Mar 22, 2025

Biscuit's interior is close to being ready for paint, and reassembly of the various settee cleats, but first, a bit of fairing for the coachroof fastener penetrations is required. I also had a bit more fairing to do on the repaired vertical surfaces in the space that the head was formerly location - aft of the v-berth.

With a small pneumatic die grinder, I worked my way around the outboard overhead surface, removing thickened epoxy than was pushed through the original toe rail fastener holes, as well as cleaning up unsightly fiberglass from the original layup. I redoubled my efforts with the Makita 9031 1" sanding belt - roughing up the overhead surface where the small 5" sander could not access. I moved around the interior of the boat from the companionway bulkhead at starboard to the bow, and then back to the port companionway bulkhead. I then pushed myself, on my back, as far aft as I could into the starboard quarter berth to repeat the process of grinding smooth and generally roughing up the surfaces of the narrow overhead. I repeated this process in the port quarter berth.

With all of the "living and sailing" space of the interior sanded, I proceeded to thoroughly vacuum all surfaces: overhead, interior hull, settees, as well as interior stowage beneath he settees. Following the vacuuming, I thoroughly wiped down the surfaces with an acetone wash. Biscuit's interior had not been this clean in quite some time.

I finished the day with application of fairing compound to previous coach roof fastener penetrations - sealed and faired on the exterior, yet still visible from down below. I filled the various voids with a combination of 406 colloidal silica and 407 low-density fillers thickening the epoxy. I had also ground these voids out with the die grinder. I then moved forward and applied this thickened epoxy to the voids existing below the recently repaired deck cleat location.

Finally, I mixed some additional epoxy and thickened it with 410 microlight fairing compound, and applied this fairing compound to the vertical surfaces just aft of the v-berth, in the space where the head was once mounted. Some fairly quick sanding in the near future will lead to paint down below, which will totally transform Biscuit's interior.
