Painters are again a specialised bunch. As well as having to colour walls an in depth knowledge of papering, graining, marbling and aging down is required. One often has to achieve a perfect surface in record time and mix colours exactly to references. A knowledge of all different paints and finishes is required plus an ability to quantify amounts and mark out. Often a scenic artist will need assistance in laying in backings and preparing other surfaces. A talented painter is a great asset to any set designer.
