Don Silsbe Posted January 4, 2015 Posted January 4, 2015 Gee, thanks guys! I'm just starting my boat, but now I'm gonna have nightmares for months about painting her. Good stuff, though. Thanks. Really. Quote
Chick Ludwig Posted January 4, 2015 Posted January 4, 2015 Heck, I've been trying to get a good paint job for years and STILL mess up. Of course, fooling around trying to save money on the right paint, or shortcuts in labor might have something to do with that! Quote
russell Posted March 23, 2015 Posted March 23, 2015 I have what might be a rather ignorant question, what is the advantage or using epoxy on interior of cabins before painting? I've had some very old wooden boats some from the late 40's and even a Chris Craft and Owens cabin cruisers, all were painted and or varnished.The Chris Craft Cavilier spent some time at the bottom of the sea due to a hurricane. I restored it. The paint and varnish was in good shape as was all the wood. Epoxy is expensive and is hard to sand seems to me a a good primer and enamel would be less expensive and much easier to apply. Quote
Hirilonde Posted March 23, 2015 Posted March 23, 2015 Comparing what is good for traditional plank on frame boats to what is good for epoxy and plywood boats is not only of no value, it will lead to bad practices. Traditional boats are designed and built such that the hull is pickled by salt water and meant to stay wet. Waterproof is attained by factoring in expansion and contraction of the wood. Flexible caulking (cotton and oil based pastes) is a key ingredient. Modern plywood construction uses an extremely stable material (plywood) that is joined with a solid and un-moving joint. The whole thing is encapsulated with epoxy, or cloth and epoxy as a barrier to resist any moisture from getting into the material. What is good for one is almost always bad for the other. So back to your question. Are you asking if it is a good idea to consider skipping the epoxy on the interior of a B&B build? Quote
russell Posted March 23, 2015 Posted March 23, 2015 In short, yes, all the joints in the interior will be epoxied and and taped as is the exteriors. I'm talking interior parts such as bulkheads (above the bildge) sloles and open cockpit would be epoxied and glassed as needed. The Chris Craft and Owens were plywood boats screwed and glued with water based weldwood (I think). Quote
russell Posted March 23, 2015 Posted March 23, 2015 Sorry, I didn't tell I am building B&B OB 24 #2. I have noticed looking at Blue Jacket Boats that large areas of cabin wood that has been epoxied and many times not as smooth as could be if one used just good paint. As I said before, sanding epoxy smooth for a good paint job is labor intensive not to mention the time table to recoat epoxy before cure. I'm not lazy but just wondering if it's really necessary. Thanks for your input. Quote
Hirilonde Posted March 23, 2015 Posted March 23, 2015 I guess the answer is that necessary is a relative term. It will also depend on the conditions the boat will see. If it is an open cabin, well ventilated 24/7 then a good paint or varnish will last many years. There is little better than a good 3 coat epoxy shell and it will stand up to layers of mildew and come back with a good cleaning and maybe touch up the finish. I would probably wait until all else was epoxy coated and hope I still had the ooooomph to finish that way. Quote
