The brown (second) coat then adds mass and surface to the plaster, followed by applying the finish (third) coat over a partially dry basecoat. The scratch (first) coat establishes the bond, or keys, with the base substrate. Three-coat work: A three-coat system is generally used with metal lath or direct masonry bases. The finish coat can be applied so that it creates either a smooth or a textured surface. Two-coat work: If using a two-coat conventional plaster system, the base (first) coat is applied to the gypsum lath or masonry base, leaving the surface sufficiently rough and porous to provide a suitable bond of the finish (second) coat.
