ASTM D3805/D3805M-16 PDF Download

The ASTM D3805/D3805M-16 standard provides guidelines for the proper application of asphalt-based, solvent-type, fibered or nonfibered, aluminum-pigmented roof coatings. These coatings are utilized to protect roofing materials from solar reflection and to enhance their decorative qualities.

The successful and long-term application of aluminum-pigmented asphalt roof coatings requires suitable application methods, which can be achieved through appropriate specifications outlined in this guide. Designers, specifiers, and contractors can utilize this guide to develop specifications for surface preparation and application of the roof coating.

It is important to note that this guide is not exhaustive, and manufacturer's application instructions should be consulted. Additionally, considerations for geographical "area practices" should be taken into account. For the acceptability of procedures and products, it is advisable to consult both the membrane manufacturer and the coating manufacturer.

This guide specifically covers the application methods for nonfibered and fibered aluminum-pigmented asphalt roof coatings, excluding the use of asbestos fibers. It can be applied to various surfaces including asphalt built-up roof membranes, modified bitumen roof membranes, bituminous base flashings, concrete surfaces, metal surfaces, emulsion coatings, and solvent-based coatings. However, it does not provide guidance for the selection of a specific aluminum-pigmented asphalt roof coating type for a particular project.
