Wrong time of year I know, but I want to do this as soon as it starts to warm up so best to be prepared.
The back of our 3 storey house faces south so, even in these less than tropical climes, it gets a lot of sun and (sometimes) heat. We have an array of sash windows, each with a stone cill on the outside. Much of the paintwork on the timber is holding up for the moment (with a few exceptions) but the cills are in a bad way, with curls of paint (multiple layers) flaking off. The cills at the front are nowhere near as bad. I presume the problem started with poor surface preparation on the first coat and/or there has been some incompatibility with subsequent layers.
Whatever the issue, I'll have to scrape the cills back to bare stone and start again. On the basis that the bare stuff being exposed to the elements for a bit shouldn't be a problem, I'll go through them in turn, then paint the lot in (hopefully) one go, ideally in the spring without the full force of the sun on the job as I'm painting.
So - what's the paint to use in this circumstance? I don't really want to spend a load of time on this only for it all to peel off again and I don't mind spending a bit to ensure the job's a good 'un in the long term. Although it's not such an pressing problem, any experience with painting wood in this position would be appreciated too as there are a few places that could use a lick.
Cheer chaps.
