    I am using wood to build the cabin of my Luhrs. I simply want to paint the interior instead of going through the unneccesary hassle of glassing and sanding a lot of surface area. Should I just seal it with epoxy, and then spray primer and top coat, or is there a better way to do this?

    Well, I thought you needed something for the paint to stick to, instead of applying 3 coats just to build over the soak through. I'm using Awlgrip, so I figure the less I use the less expensive it'll be on my Marine Corps salary. So the wood itself will give a good enough surface adhesion? I've painted wood before with 1 part Interlux, so I guess it would work even better with Awlgrip.

    So just seal the wood, here's the problem if you seal the wood with epoxy on one side...
    unless you spend the time to seal the wood on all 6 sides you are waisting your money on epoxy.
    moister will still get into the wood and it will peel off just like old paint.

    Interior on your Luhrs should not allow that much moister in and so you should be able to just use a wood sealer and paint.
    Why use Awlgrip, exterior OK I can see but once again, why go through the expense.

    Go with easy poxy or Interlux and be D U N ( done).
    To be perfectly honost, I use PPG car paint and holds up just as good as Awlgrip.
    All I'm saying, why make it harder than you have too.

    I am also looking at using Imron, but forgot about PPG- another good paint that probably coast less because it doesn't say "Marine" on it LOL. So in lieu of easypoxy, would any single part poly work fine then, like Interlux?

    I am glassing the exterior BTW- just not the interior. This thing is being built like a waterproof tank!

    If you epoxy any part of the wood epoxy all 6 sides I can not stress that enough...interior or exterior...I do not want to sound flip floppy but if one side of the wood is exterior and the other is interior then yes it would be a good idea to epoxy all sides.. good rule of thumb. But if it is all interior then no epoxy needs to be used.Still I still would use PPG paint

    The interior doesn't need epoxy or awlgrip either. A single part high build primer and two coats of single part urethane such as Easypoxy (or Petit old salem semigloss white). Wood does better with a softer paint since it expands and contracts more than would allow a two part paint to stretch, meaning cracks at joints, etc.
    A single part will go twenty years and then some inside the cabin. Why spend on the scary chemicals?
    Ask any wooden boat builder----- they prefer single part paints for good reason.

    What do you paint your house with? the outside of course! that'll do, you may have to do it annually but hell it's cheap, and as the man said why go using scary chemicals if you don't have too?

    Once you get a few coats on you won't know the difference

    Thanks for the advice everyone! This weekend I actually got all my interior panels prefabbed at the house, and gave them all a thin coat of epoxy just to seal it so I wouldn't loose paint to soaking in. I'm gonna run some 220 over the whole interior to get rid of the fuzzies (another reason to coat with epoxy- to harden fuzzie making easier to sand) and after a quick alcohol wipe I'll try to shoot the whole interior with a quart of Easypoxy or Interlux. Thanks for making this easier, and less expensive!

    Epoxy makes a good primer for relatively smooth surfaces, which hopefully need only be sanded, as you say, with 220 grit. Epoxy's a lot harder than single-part primer, so it may be necessary to prime over it just to fill and build.
    Good luck!

    I find epoxy is the best but the conditions MUST be perfect! Perfect conditions do not exist on a boat - especially if it's a afloat!

    IF you can park your boat in an enclosed shed with perfect weather conditions, paint it and leave it for some time until all is set - great! But most people actually want to use their boats, why not that's what it's for!

    So why not use something that does work in all sorts of bad conditions, house paints are pretty good at this - OK maybe you gotta do it more often, but at least you can afford it (change your colours regularly to!)..............just a thought! what ever route you take the best of luck Mongo, enjoy

    My plan is to get the hull done and several coat of paint
    on before winter so I can work in the little shop at home
    doing the seats and floors and trim and everything will be
    good and set next spring!

    They call for five coats BTW! Inside and out!

    Well, my boat right now is nowhere done- I still got about another 6 months AT LEAST before she ever sees water, so it's easy to paint her on a trailer. In reference to the cost of paint, Interlux is GREAT stuff for an interior, but it's also $40 + tax a qt. Lowes hardware on the other hand, sells a "Marine Topside" enamel made by Rustoleum. Not my first choice, but at only $10 a qt, I'm trying it. Put one coat on a few small parts (drawers, cabinet faces) and it looks pretty good so far, but using a chip brush wasn't the best idea. SO I will sand down the parts and then spray them, it should come out pretty damn good then.
