    Significance and Use

    The intent of this guide is to provide information and guidelines for consideration by the designer or applicator of joint seals in, or adjacent to, EIFS. Refer to Specification E2568 for additional information pertaining to specifying Class PB EIFS. Refer to Guide E2511 for additional information pertaining to detailing of EIFS-Clad Wall Assemblies.

    Proper selection and use of a sealant is fundamental to its ultimate performance, service life, and durability. A sealant joint subjected to movement and other similar performance factors should be designed for the particular application to avoid compromising its performance capability and causing failures. Refer to C1193 for guidance.

    In addition to the design and installation data in this guide, consult the sealant manufacturer about applications for its products and their proper use and installation.

    1. Scope

    1.1 This guide describes the use of single and multi-component, cold-applied joint sealants, or precured sealant systems for joint sealing applications, or both, in buildings using Exterior Insulation and Finish Systems (EIFS) on one or both sides of the joint. Refer to 10.1 for joint seal geometries.

    1.2 The elastomeric sealants described by this guide meet the requirements of Specifications C834, C920, or C1311.

    1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.4 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.

    1.5 There are no ISO standards similar or equivalent to this ASTM standard.
