had the hall and stairs re-plastered 6 months ago . It was mist coated and 2 coats of emulsion . All was well till yesterday I noticed that behind the radiator at the bottom of the stairs the paint has flaked off and left bare plaster and in one area the top coat plaster has come off leaving the undercoat plaster . I cannot see what caused it or what to do to repair it .
Can anyone help.
