Veneer plaster systems use a gypsum core panel as the base for the plaster coat. This panel has a gypsum core very similar to drywall. However, the paper used to cover the gypsum core is different from regular drywall. It is a special multi-ply paper. The top ply has the capability to readily absorb water and provide a good bonding surface for the plaster coat. The bottom ply, however, is water resistant. This ply protects the inner gypsum core from being softened by the water in the wet plaster. Some manufacturers use a special blue paper on this gypsum panel. Plasterers often refer to it as "blue board." Special plasters were developed which allowed a one step finishing process. This plaster is applied in a thin coat directly over the gypsum panel. The plaster thickness usually ranges between 1/16th to 3/32nd of an inch. Conventional plasters were often 1/2 inch thick.
