This technical manual has been prepared by the military services to provide complete uniform information and establish standard practices for the painting of buildings, structures, and fixed equipment. Advances in paint technology have led to the development of many coatings formulated to meet specific requirements and conditions. Generally, more than one painting system is well suited for the combination of surface, environment and service required. Similarly, surface preparation, the choice of equipment, and the method of application may vary according to the severity of the exposure, the coating used, and the conditions under which it is applied. Each of these factors contributes to the effectiveness of the completed job. The purpose of this manual is to describe proper methods for surface preparation, to delineate satisfactory paint systems, and to recommend proper procedures for application of these paint systems to effectively protect and economically maintain a variety of surfaces.
