Green Seal Weighs New Coating Standard
Concrete and masonry sealers, intumescents and other high-performance coatings may have their shot at green certification under expanded standards now being drafted by Green Seal.
The non-profit certifying organization is seeking public input until Aug. 21 on whether and how to modify, expand or combine its GS-11 standard for paints and coatings and its GS-47 standards for stains and finishes.
Current Standards
GS-11 establishes product performance and health and environmental requirements for paints and coatings. The standard includes wall, anti-corrosive, reflective coatings, floor paints and primers and undercoats.
The standard does not include stains, clear finishes, recycled (consolidated or reprocessed) latex paint, specialty (industrial, marine or automotive) coatings, or paint sold in aerosol cans.
GS-11, first published in 1993, was last revised (to Edition 3.1) in July 2013. The third edition encompasses GreenSeal's GC-3 criteria for Anti-Corrosive Paints.
GS-47 is intended for products generally applied to metal and wood substrates and includes sealers but does not include paints, floor polishes, specialty (industrial, marine, or automotive) coatings, or products sold in aerosol cans.
What Might Change
Green Seal is currently considering the following product categories for inclusion in the scope, for both interior and exterior use:
The organization’s current review has focused primarily on identifying product categories that could be added to the scope of the standards—mainly those used for similar purposes or with similar chemistry.

Anti-graffiti coatings could be included in Green Seal's new categories. |
The GS-11 criteria exclude clear, tinted, and transparent architectural coatings; and floor coatings other than latex paint. These products are not included in GS-47, which includes only products intended for use on wood or metal surfaces.
Public Input Invited
Members of the public may email GreenSeal with suggestions for additions to the standards. Submissions may include:
