Hi,

As some of you may remember I took out Little Plums ghastly purple/dark red vinyl headlinings in the main cabin. So I am back down to the naked grp - albeit with some glue residue remaining. As we are coming back into winter, although I must have blinked because I missed summer somehow, it is time to redecorate. It is all lovely and dry down in the cabin now - assisted by an electric oil filled radiator that I leave set to minimum when I am away from the boat.

The plan is to paint the interior. Rob ( Snifter ) had a look at the balsa core and says that there is nothing wrong in that department (whew !). I think I will have to take a rotary wire brush to the glue residue to get that stuff off. My main query is having prepared the GRP surface, what should I prime it with ? Is there any real need to use an expensive International primer, or would a normal grp primer do the job. The top coat will be be matt white or very light grey. I am worried that a gloss finish would look rather harsh in such a small area. Someone has suggested bathroom paint, but apparently this can be quite soft and is not really designed for structures that flex a bit.

It should look quite nice as it will be textured by the glassfibre mat weave.

The headlining used to hide some of the wiring (12V lighting). It could do with replacing, so I will get that into some sort of conduit. At least it will mean that I can get to it without having to take the headlinings off again.

As ever any comments or advice would be very welcome.

Cheers

I heeded the recommendation to use Dulux Weathershield Exterior Satin Brilliant White for internal painting. It applies well, is water based, and gives reasonable results (for an amateur) - only 2 coats from bare GRP. I'm never without a tin.

Bathroom paint is anti condensation and I have used it with a tiny bit of success, but you never win against damp. Paint rule I have in Turkey is do not paint feb march as it could rain. Do not paint July Aug as it is too hot, better on the bar terrace with a cold beer. Rest of the year no cloud, dry and about 30 deg C. Seems to work better than Aberdeen for some reason.

We painted Skykomish's interior with Anti Condensation Paint (bought on e bay). It is from what I can see not much more than white emulsion. The idea being a matt finish does not attract condensation the way a gloss does (?) having said that we have certainly found that the areas painted with this suffer less from mould during the winter months.
Have to say we hate the GRP weave effect on the interior panels and plan to cover this with either vinyl or timber as soon as we can afford it.
I am considering using pine cladding from B&Q as this is very cheap and comes in a finish that looks similar to very narrow planking.
Then paint or varnish this.
Cord type carpet is very good for beating condensation and is both cheap and easy to use giving a fairly pleasing result if subdued colours are used and it is used in moderation

Hi Gee,
I've just put Snifter in for the winter racing season having done a very quick refit and tidy up below, and rewiring. I used some white shower paint I found in B & Q, which I also used on Amrum. It goes on easily and has a matt white finish and is supposed to prevent mould growing.
I'll check out tomorrow what it's called and let you know. I also ought to take some photos of the finished job. She's very stripped out for the winter as I won't be sleeping aboard.

I also use that exterior satin (on the outside of my boat!) and use acrylic paint on the inside which did a fantastic job.

Acrylic eggshell is made by Dulux and Crown and is the thing being water based and sticks to anything.

Yes! Acrylic eggshell, that's the boyo I used and was very happy with the results.

Dulux Bathroom white satin sheen with Mouldtec! Has worked very well on the insides so far.

Sadolin Superdec available in satin or gloss can be used internally and externally. Great product and it covers better than weathershield. Oh and its waterbased.

Sadolin is the other acrylic that I forgot, tested by PBO over a 10 year period and rated.
