Green Seal, an independent nonprofit certifier of sustainable products and services, revised and expanded its GS-11Standard to apply to floor coatings, concrete and masonry sealers, and fire-resistive coatings, in addition to the paints, primers, anti-corrosive coatings and reflective coatings previously covered. Clear and transparent coatings also are included in the 24 product categories that are now eligible for certification.

The new Green Seal standard offers greater flexibility for the assessment of VOCs and aligns with VOC limits set by the California Air Resources Board. It also: addresses stains and finishes for wood and metal (previously covered by the GS-47Standard); ensures that certified paints, coatings, stains and sealers deliver satisfactory performance; and restricts a comprehensive list of harmful chemicals.
