The works process involved an initial survey to assess the physical condition of the area and documentation of any damage on CAD drawings. Once this had been done, each area was dry-cleaned by using soft brushes to sweep dust into a low suction vacuum cleaner.
Cracks were then filled with a colour-matched mixture of acrylic filler, white paint and pigments. Peeling paint was gently consolidated and re-adhered with a 1% solution of acrylic emulsion.
Above the ceiling, floorboards were lifted to check the integrity of the ceiling structure and to inspect the condition of the lathing above areas of cracking. Three holes that had been cut for the insertion of fire aspirators were also filled with tailor-made plaster of Paris ‘plugs’ which were suspended from above with stainless steel pins.
During the works, plaster, paint and dust samples were taken for recording and analysis. Any observations about construction detail of the ceiling were also noted.
