(Specification)Standard Specification for Liquid Applied Acrylic Coating Used in Roofing
Standard Specification for Liquid Applied Acrylic Coating Used in Roofing
ABSTRACT
This specification covers testing and material properties of water-dispersed protective roof coatings composed of a water-based acrylic latex elastomeric emulsion polymer, to which various pigments and other additives have been added to give the required physical properties. The product, as manufactured, shall be in liquid form for application to the roof surface by brushing, squeegeeing, rolling, or spraying. Guidance for its application is not addressed here. Coatings shall be tested and adhere to liquid property requirements as to viscosity, and volume and weight of solids. Conversely, films shall also conform to dry physical properties, as follows: initial percent elongation at break; initial tensile strength at maximum stress; final percent elongation at break after accelerated weathering; permeance; water swelling; adhesion; fungi resistance; tear resistance; and low temperature flexibility after accelerated weathering.
SCOPE
1.1 This specification covers liquid-applied water-dispersed acrylic latex elastomeric protective roof coatings.
1.2 This specification does not provide guidance for application.
1.3 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.
1.4 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, health, and environmental 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.
