Our hallway ceiling has nasty textured ceilings and therefore as we want a smooth finish I have ripped down the old plasterboard & reboarded the ceiling, and will get a man in to skim. Anyway, stupidly, I reboarded brown side visible, even though on the board is says plaster other side. Will having the brown side down be a problem or an i going to have to take the boarding down & re-do?
