I've had the walls in my lounge re-plastered (skimmed over artex) 4
weeks ago and have bought some Dulux Supermatt to paint them. However,
I've been told that Supermatt is not very hard wearing and will mark
up much more easily than normal matt paint. I'd rather not have to re-
paint them sooner than absolutely necessary so was wondering whether
to wait a bit longer for the walls to dry out (the plasterer says 6
weeks). What do you think? Is Supermatt ok? Or do I really need to
wait before using normal paint? I'd appreciate your advice.

If it was just a skim coat, I would say wait for a week after it
looks dry (gone back light colour). If it was a scratch (under-)
coat too, then I would wait longer. Matt paint can breathe, but
if you are using a silk or gloss paint, then it's even more
important that the plaster is fully dry.

You need to use a special first coat on bare plaster, otherwise
the first coat will likely come off, usually when you are putting
the second coat on or shortly after you've finished the painting.
You can get special paints for this, but watered down matt
emulsion works very well too. Don't use PVA though.
