Mist coat new plaster two times. To begin, mix a watered-down emulsion paint (70% water, 30% paint) and apply the first mist coat to seal the plaster and prevent it from soaking up too much paint. Allow it to dry completely before applying the second mist coat. This process helps achieve a smooth and durable finish while ensuring the plaster is adequately prepared for the final coats of paint.
