Abstract : Four specification coatings for masonry surfaces were applied in August 1961 to two concrete buildings in the Naval Civil Engineering Laboratory complex. Their condition was examined at about yearly intervals for ten years. Three exterior emulsion paints, acrylic (TT-P-0019a), polyvinyl acetate (TT-P-0055a) and styrene-butadiene (TT-P-0099a) were found to perform well. The cement-water base coating (TT-P-0021a) presented an unsightly appearance within two years, particularly just after a rain. Because of greater alkali resistance and lower cost the exterior acrylic emulsion paint is recommended for general use on masonry surfaces. (Author)
