Proposed ASTM Test to Support Liquid-Applied Polymers
A set of proposed ASTM International test methods will help support the growing number of roofing projects that use liquid-applied polymers. The proposed standard (WK40123, Test Methods for Sampling and Testing Liquid Applied Polymeric Roofing and Waterproofing Membranes That Are Directly Exposed to Weather) will help manufacturers, testing labs, and the construction industry as they sample, test, and compare products. It is being developed by ASTM’s committee on roofing and waterproofing (D08).
The proposed standard includes ways to test liquid-applied polymeric materials that are cured to form roofing and waterproofing membranes that are directly exposed to all kinds of weather. By their nature, these materials are seamless. They are also useful when working with complex surfaces and custom-fit projects.
