Re: Help with painting problems
Great thread and lots of good advice- virtually nothing I can add.
I'm a house painter, and no surprise that I just stick to what I know. Good (and comparatively cheap) house enamel. Works for me with a boat on a swing mooring all year.
Along the lines of Feazer's excellent points, I like to lay it on in that delicate state of just-not-too-thick to run or sag, and can't see much point sanding beyond 180 either. But then, on my boat, I am not all that concerned about 'the perfect finish'. In houses, when the client specifies (ie keep it cheap as possible), with a good prime/undercoat and sand, from raw timber, it is not all that hard to get a satisfactory finish with even one topcoat. Two and your laughing.
I've never tried these fancy marine paints, and from the lengths it seems people have to go to get that perfect finish, I am in no rush to change that (more power to you guys that go after and achieve what you want here)
For rolling and tipping I much prefer a good worn in (the first few uses with drop hairs) 'mohair' sleeve (specifically made for gloss paints) than a foam one. Less likely to drip, leave tracks and bubbles, and holds a decent amount of paint while laying it on in a more consistent manner IMO. YMMV.
The only trouble I've had with house enamel is going after the colour we wanted first, and accepting the base it had to come with. This was a clear or 'extra bright' base- first time I used it- on the boat. Covered appallingly and is just generally a nightmare to use.
Matching colours already down, for recoats on commercial jobs (offices etc)- lately- this clear 'extra bright' base has been the bane of my existence. On my own stuff, or in working where I have the choice, I will now only be using colours that come in a proper base (tinted from white, or a true colour base with tints) as the paint is so much better and usually covers in literally one coat.
In offices (air con) and hot houses, (and much the same as I would imagine professional boat painters are faced with) one often doesn't have the luxury to pick and choose the perfect conditions of when to do the job- this is where rolling and tipping helps us. We do big mirror finish high gloss office doors with two people- follow your system, rip through it and onto the next one. Often one person could do it alone, but it just works better for us this way.
All I would say is, Longbow, for whatever paint you are using, follow up on your idea to do some practice coats on the type of surface and angles that are giving you problems- then once you figure it out take it to the boat. And don't sweat the details too badly! As said, there is always next time, and the time after that.
In the end, I look at paint, on my boat, 'utilitarianly', as a pleasantly (hopefully) coloured protective covering. That is about it for me. No obvious drips, runs, orange peel, etc, well that's nice too, but aint going to break my heart if there are a few exceptions.
I leave the quest for that 'perfect finish' for moments when some-one else is paying for my time
Best of luck.
One path leads to despair and utter hopelessness. The other, to total extinction. Let us pray we have the wisdom to choose correctly.
