1.1 This practice covers the minimum requirements and procedures for field or prefabricated application of Class PB Exterior Insulation and Finish Systems (EIFS). Class PB EIFS are systems applied over insulation board, in which the base coat ranges from not less than 1 /16 in. (1.6 mm) to 1 /4 in. (6.4 mm) in dry thickness, depending upon the number of nonmetallic reinforcing mesh layers encapsulated in the base coat. The base coat is then covered with a finish coat of various thickness in a variety of textures and colors.

1.2 This standard does not cover Class PB EIFS with drainage. Consult the EIFS producer for information.
