Thanks for the advice. I suppose I could get all that stuff done first, it's not me doing that part?Just noticed you are considering painting them before they are fitted - which suggests they haven't had the hinges and locks cut, doors handles fitted etc etc.
No way do you want to put the gloss coat on before this is done.
The doors will get scratched and marked and chipped.
And if the paint hasn't fully cured before fitting, you risk the soft paint getting 'torn' and it becomes a sticky mess.
I highly recommend you wait until they are fitted before glossing. You can always use a small heater in the outhouse to take the chill off.
I would normally hang them first it's just the time of year. I'm concerned to have them outdoors all winter with just primer but perhaps I needn't be?
