(Specification)Standard Specification for Surface-Applied Bonding Compounds for Exterior Plastering
Standard Specification for Surface-Applied Bonding Compounds for Exterior Plastering
ABSTRACT
This specification covers the minimum requirements and test methods for determining the performance and physical properties of exterior surface-applied bonding compounds. These compounds are used for the improvement of adhesion of cementitious materials to concrete, other masonry surfaces, or any structurally sound surfaces. The methods described here are tested for surface applied bonding compound composition, consistency, film characteristics, re-emulsification, bonding capability, degradation, high temperature performance, freeze-thaw stability, and tensile bind strength.
SCOPE
1.1 This specification covers minimum requirements for exterior surface-applied bonding compounds for improving the adhesion of cementitious material to concrete or other masonry surfaces or any structurally sound surfaces.
1.2 This specification also covers test methods for determining performance requirements and physical properties.
1.3 The values stated in inch-pound units are to be regarded as the standard. The SI metric values given in parentheses are approximate and are provided for information purposes only.
1.4 The following safety hazards caveat pertains only to the test methods described in Sections 9, 10, 11, and 12 in this specification: 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 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
