Guest Cabin - The top of the outer wall
panels were delaminating. The decision was made to replace
the panels with new Luan.
In order to present a clean neat appearance, any unused
brackets, screws, plumbing or wiring was removed. Any
protruding screws were cut off. The exposed hull planking
and framing were inspected and found to be dirty but sound.
The hull frames, seam battens and planks were scraped and
vacuumed. Even though it would not be seen all the inside
planking, seam battens and hull frames were cleaned with a
mixture of water, TSP (Tri-sodium-phosphate) and bleach.
Abandoned screw holes were plugged with toothpicks. The
toothpicks were coated with West System 105 / 205 epoxy and
then taped into the screw holes. Later the ends of the
toothpicks were broken off and the wood sanded smooth with
120-grit sandpaper.
The hull frames, seam battens and inside hull planking were
painted with Interlux #863 - Bilge-kote Gray.
The length and width of a replacement panel was
cut from 1/4" Luan and dry fitted.
The outboard side of the wood was painted with three
applications of West System 105 / 205 epoxy. The epoxy was
thinned 100% by volume with lacquer thinner to the
consistency of water. The epoxy was applied with a foam
roller and then tipped off with a brush to remove any
bubbles. When applied, the diluted
mixture soaks into the wood, where the epoxy cures and the
solvent evaporates. The process
dramatically slows the migration of
moisture, but does not act as a "water-proofer."
After each application had dried for 24 hours, it was
lightly sanded with 120-grit sandpaper. The whited-out epoxy
was then vacuumed and wiped-down with a cotton towel and
paint thinner.
The new panels was tacked in place and the portlight opening
was drawn on the outside of the panel. A jigsaw was used to cut out the
opening for the portlight.
The panel was then fastened to the main hull frames using
#16 - 1” brass escutcheon pins.
In
preparation for the finish paint, two coats of
Interlux – Pre-Kote White primer were rolled and tipped using a
1/8” nap foam roller and a 2" foam brush.
After each coat had dried, the paint was smoothed with 220-grit
sandpaper. The primed wood was then rolled and tipped using a
1/8” nap foam roller and a 2" foam brush with
two coats of Interlux Brightside - White. After the
first coat had dried, the paint was smoothed with
220-grit sandpaper. Before final painting, the wood
was vacuumed and then wiped-down with a tack-rag
and paint thinner.
