I recently (Thursday) got my hallway plastered. The plasterer said he'd send a painter round to finish the woodwork and paint the walls. He came this morning, and I said please just do the woodwork because the plaster wasn't dry (it's only been a day and a half and it's still changing colour, some bits are darker than others). I went into another room and when I came back he'd painted the walls. I said I thought he was going to leave the walls and he said it was fine, they were dry and he wouldn't have done it otherwise. So he just ignored me, basically.
What am I dealing with, here? My concern is that the plaster is now never going to fully dry because the paint will seal the moisture in (it's damp proof paint so not breathable). If this happens, what is the damage risk? Might there be any damage to the brickwork? Might there be a smell? What is the worst case scenario I'll have to deal with?
