The composition of the primer will vary depending on the type of finish coat used. A smooth, white finish coat goes on last. Some sanding of the finish coat is usually required to get a smooth surface. The finish coat should be worked to match the texture of the original stucco. The finish coat usually contained an integral color and was typically textured for appearance. The finish coat can be troweled smooth, hand-textured, floated to a sand finish or sprayed.
