Does it matter much if I do the 'cutting in' the day before I paint the walls with a roller?

Would doing a wall at a time help?

No, that would mean cutting in each corner twice!

Well you said " any thoughts" so I have given you one .

You said you think it won't show but my understanding was that the rollering should be done straight after the cutting in while it ( the cutting in ) was still moist .

As for cutting in each corner twice not if you keep to ONE wall.I think that would show less than what you propse yourself ....far better to take a day or 2 off work if that's the problem and do it all like it should be .

sorry, didn't mean to be rude.

I think I'll try it with the first coat and see how it looks....

No it wouldn't. You just run the brush down the corner and lap onto each wall by, say 3 inches, then roll one wall. Yes the other wall's edge will be dry by the following day, but you are suggesting doing it all like this in your OP.

FWIW, I can't see a problem with it - I've touched up patches days or even weeks later and they are not visible

I agree, though the matter the paint the better, for that.

what?

what?

Yeah .That's what I said as well at first reading...Matter as in More Matt ...More Vinyl Matt as opposed to Slkier as in More Silk ,More Vinyl Silk .

My experience as well.

I find that with flat matt emulsion you can touch up imperceptibly weeks after applying it. Flat matt, as opposed to matt, or silk. I like flat matt. Posh paints and chalky paints.
