We have just completed an extension. The interior walls have been plaster boarded and plastered. On the edges under the plaster are metal strips which the builder said stopped the plaster from shrinking.
We sealed the plaster and have applied a 3 coats of paint. Each time there are spots in the pattern of the metal strips appearing on the painted surface. They look light wet paint but are dry.
We have tried re sealing with PVA and painting over but the same happens. Does anyone have any other suggestions.
