Report Ceiling plasterer in Consumer Advice Posted February 20, 2021 17 minutes ago, Rasmie said: We had the ceiling plastered in one room . Seemed to take weeks to dry and so we had the next room plasterboarded. I.e. overlaid the original ceiling. Slightly more expensive by much much quicker. @Rasmie thanks for that, I think due to the ceiling looking like a Christmas cake that plasterboard will be the quickest solution.
