WHAT GREEN SEAL CERTIFIES
Green Seal’s GS-11 leadership standard means a paint, coating, stain, or sealer is verified as safer for human health and the environment compared to similar products while delivering uncompromising performance. The standard covers wall and ceiling coatings, anti-corrosive coatings, floor paints, primers, stains, finishes, and sealers intended for application to wallboard, tile, metal, wood, composite wood, concrete, stone, masonry, and terrazzo substrates, as well as other architectural substrates.

PERFORMANCE OF GREEN
All Green Seal certified products must demonstrate functional performance via an objective, scientifically validated method under controlled and reproducible laboratory conditions. Paints, coatings, stains, and sealers must meet ASTM standards in relevant areas such as adhesion, applicability, scrubbability, and washability.
SCIENCE OF GREEN
Our Green Seal Compass guides every certification. Our science-based standards define sustainability leadership in the marketplace and reward industry innovations. Only the healthiest, most responsible, and most effective products achieve the Green Seal. The Green Seal Compass focuses our standards on key impacts that occur throughout the product life cycle, from raw materials extraction and manufacturing to packaging, use and disposal.
