ASTM C1397

This practice provides minimum requirements for the application of Class PB EIFS and EIFS with Drainage (see Specification E 2568). The requirements for materials, mixtures, and details shall be contained in the project plans and specifications. See Guide E 1825 for guidance.

1. Scope

1.1 This practice covers the minimum requirements and procedures for field or prefabricated application of Class PB Exterior Insulation and Finish Systems (EIFS) and EIFS with Drainage. 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 ¼ in. (6.4 mm) in dry thickness, depending upon the number of nonmetallic reinforcing mesh layers encapsulated in the base coat (see Specification E 2568). The base coat is then covered with a finish coat of varying thickness in a variety of textures and colors. EIFS with Drainage provides a mechanism to drain incidental moisture

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 The text of this practice references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as a requirement of the standard.

1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
