ASTM-D7120 › Standard Guide for Evaluation and Preparation of Roof Membranes for Coating Application
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This guide covers the procedures for evaluating and preparing non-aggregate surfaced membranes for the application of a coating. It does not address design, construction, or installation issues regarding the roof assembly or the roof membrane. It is not an application guide for roof coatings.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 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.
Significance and Use
This guide outlines the general procedures necessary to evaluate and prepare a roof membrane for the application of a liquid surface coating.
This guide is not all inclusive; this guide is intended to supplement detailed instructions from manufacturers and safety requirements required by law.
