Sealing the walls and ceiling

[Juneaudave]

Question about the first coat:
Was the back side of your gunnel sealed also, or just the side showing in the pic? (IE... Does the surface that is in contact with the work bench have sealer on it also?)

Yes, the entire gunnel was coated...I was always perplexed as to why, after you fiberglassed the outside of a canoe with no bubble problems what-so-ever, that you had to constantly fight bubbles on the first coat on the inside...even with a precoat.

I still think that the best prevention for outgassing has always been the Number One Rule with epoxy...warm up the wood and epoxy to the appropriate application temp, then let the temps drop as you do the application.

Gee, I sure confused everyone with my post...I'm so sorry if I mixed up a topic about sealing wood on a Tear and maybe a finer point on glassing. That certainly wasn't my intention and please accept my apologies...Juneaudave

Does that mean I did all that for nothing. Just teasing. I don't see any harm in sealing the insides since I have the floor finish just sitting around. Truthfully if I had 3/4 walls I would have sealed both sides so...

I left the surfaces where the glue is structural unpainted. Couldn't see the point when the glue is waterproof.

To shed some light on painting surfaces that may be glued later, here is the procedure I followed.
Painted the floor, 3 coats. Built the wall framing and glued inside paneling on using yellow carpenters glue and 16" square patio blocks to clamp paneling to frame.
Used caulking between bottom of wall and floor and screwed thru bottom of frame to attach walls to floor.
Installed roof spars between walls and installed ceiling panels to roof spars.
Once everything is framed and all interior panels are installed and glued in place then I put 2 coats of paint on all exposed surfaces that weren't already prefinished. No painted parts are glued together.
This is what it looked like prior to roof insulation and application of aluminum.


The painting of the framing and back side of paneling only added a couple of hours to the build and 25 bux to the cost. I have learned from other woodworking projects [everything from house siding to furniture] that it is extremely important to finish all sides of wood to stabilize the expansion and contraction [warping one way or the other] and to increase moisture resistence.
Small effort and cost. Worth doing.
