Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This practice covers the minimum requirements and procedures for field or prefabricated

3、 application of Class PB ExteriorInsulation and Finish Systems (EIFS) and EIFS with Drainage. Class PB EIFS are systems applied over insulation board, in whichthe base coat ranges from not less than 116 in. (1.6 mm) to 14 in. (6.4 mm) in dry thickness, depending upon the number ofnonmetallic reinfor

4、cing mesh layers encapsulated in the base coat (see Specification E2568). The base coat is then covered witha finish coat of varying thickness in a variety of textures and colors. EIFS with Drainage provides a mechanism to drain incidentalmoisture1.2 The values stated in inch-pound units are to be r
