Hi,
We recently had some plastering done to create a fireplace "alcove" on the chimney breast in our dining room. The plasterer created a "box" with plasterboard and then skimmed a small amount (max 5mm deep) of plaster over to make it flush to the wall. We left it about 10 days to dry.
Last night I painted a base coat of emulsion over the plastered area to ready it for painting today. However, overnight two very small patches (about 5cm diameter each) of flaking paintwork have appeared. I have no reason to suspect that the plaster work should be still damp, the plaster having been so shallow anyway and having left it for a reasonably long time with the heating mostly on. Is it safe just to sand these areas down and repaint?
