I had 2 internal walls plastered 24 days ago, one was skim over artex (with block wall behind) and the other a stone wall, on which the artex had been mechanically removed in places and had some areas patched then skimmed. Over the first week most of the plaster dried pale pink, leaving some darker patches on both walls, all in the top half of the wall and predominantly above 6'. Since then the darker patches have got a bit lighter but still remain on both walls. There has been no discernible change in the last 10 days. Windows have been open on dry days and a log burner lit on wet days. We have high humidity living next to a reservoir (plus recent wet weather).
Do I just need to give it more time before painting and wait until the finish is evenly coloured?
