Painting Inside of Cabin?

[Pye_End]

I've used danboline and sadolin superdec (after reading Richard Hares PBO article). Danboline is rubbish in comparison - cracks, flakes off etc unless your preparation is scrupulous. It also yellows more with age in my experience. I have one quarter berth side / ceiling painted with Danboline and one with Superdec painted within a few months of each other - wouldn't ever buy Danboline again. All my opinion of course, and Richard Hares I guess

I do not recognise this - perhaps my Danboline has a different formulation. I have used it on the ceiling above forepeak bunks. A little light sand but very little preparation. Did it 10 or 15 years ago and is still good. Never had any flaking/cracking and no yellowing. Perhaps (particularly with other comments in this thread) it depends on what it is going on? Mine was onto GRP with some sort of white finish - perhaps a thin flowcoat. What did yours go on to?

Same here, although quarter berths more exposed to the sun with the hatch open, so more likely to yellow?. I'm guessing the problem may be damp - not unusual when you do your maintenance in the UK in winter. The superdec breathes, stays flexible and seems to adhere better. OK - Danboline isn't rubbish, it just is in comparison in my view

Just seen on the danboline application guide that particular attention is required when it comes to painting the back of moulded GRP surfaces - in terms of cleaning and sanding. It doesn't seem so critical with superdec

That's exactly what I did several years ago and it has been fine. Emulsion is cheap, easy to apply and to re-coat all you have to do is slap some more on. And being bathroom emulsion, it's washable.

I used emulsion on my last boat for about 15 years & I found I had to recoat it practically every year because of flaking or mould.Never again.
I guess it's crucial to have a chemically clean surface before sticking on any paint & my new boat has all the drooping headlining & old glue problem to overcome but I shall be trying something different this time & it won't be more bloody headlining's!

Danboline's formula was changed a while ago, (usual H&S rubbish!) and the modern version is nothing like so good as the original, being little more than high opacity 'ordinary' paint, nowadays.

Sadolin Superdec it is then!
