1. Hand Application over portland cement base- Prior to application of Exterior Stucco Finish, the base coat shall be sprayed with clean water to control and equalize water absorption
2. Machine Application over portland cement base - Base coat shall be dry. (It is not necessary to spray the base coat before application of Exterior Stucco Finish by machine, as the compound itself has ample moisture when mixed for this purpose.) Spray the first coat in a thin consistency over the dry surface and cover base coat completely.
After first coat has dried, which may take two or more hours depending on climatic conditions, spray second coat in a thicker consistency and bring to the desired texture. Second coat may be sprayed the following day.
