As a dedicated Classic Boat reader and wooden boat owner in the U.S., I have a few questions concerning painting wooden boats.
For a background, I have a "new" (as of July this year) old boat which is a 1959, 28' - 8" Phillip Rhodes designed sloop rigged, full keel, and strip planked (Mahogany on White Oak). She's been in fresh water for at least twenty years, sailing Lake Michigan, as I do. Much of her deadwood below the keelson was rotten, as well as a few planking areas, but is overall is in good condition. The planking (1.25" x 1.25") joints below the waterline were previously routed out approximately 1/8" wide to accept thickened epoxy to replace the failing glue, which seems to be working fine although I doubt I would have gotten the router out. The rot, I believe, was mainly due to the bottom also being coated also with the epoxy which held water just above the iron keel/ballast, as well as a few "pockets" on the planking. She also wasn't properly inspected which I seem to do continually!
The entire inside hull had been either varnished where visable or left unfinished. I have stripped the bottom and topsides of all epoxy and paint, as well as sanding the inside to prepare for proper finishes. I am planning to prime the bottom with Kirby's (kirbypaint.com) Red Lead Primer which is, of course, a very traditional paint from one of the, if not the only,
traditional paint manufacturers over here. I will then apply traditional copper anti-fouling. I was even thinking of applying green Cuprinol (No. 10) preservation before the red lead, which Mr. Kirby had no objection to. Yes, I know it's a lot of poison, but that is what is to be expected, or should be, of the bottom.
On the topside, I will possibly use Interlux (International) Prekote, followed by Kirby's semi-gloss alkyd. I would love to hear what your guys on your side of the Atlantic think of
the above? Primarily though, I have questions on painting the interior since there is plenty of varnished Mahogany (or will be!), other than the hull. I believe a white interior hull will lighten up the enviroment a bit and hold up better than the previous varnish.
Did anyone read Mr. Houston's Classic
Boat (No. 206, August '05) article which covered interior painting in detail?
Here are my questions concerning this, if I've not already been too burdensome?!:
Mr. Houston uses the Yacht Primer as a primer and Prekote as an "undercoater". My tin of PreKote (not used yet) doesn't mention using Yacht Primer before Prekote. Forgive my ignorance, but what is the difference between a primer and an undercoater? I believe the Yacht Primer contains aluminum, but I'm not sure of the advantage. I'm wondering
if Interlux is not giving us here in the U.S. the full specifications?
The finish coats Mr. Houston used were Danboline, which I believe is
"BilgeKote" here, which seems like a good idea to hold up against abrasion, bumps, etc... Any opinions on the above interior combination?
Finally, on Mr. Houston's bilges he used a water-based primer from Dulux Trade (Supergrip), then Damboline. I have always been told to never paint an oil or alkyd-based paint over a water-based paint, although water-based is usually fine over an oil-based primer. What is correct? Or would red lead be the best in the blige?
I emailed CB several weeks ago, but I'm sure they can't answer all their emails.
Thank you in advance for any comments, opinions, or suggestions.
