Standard Revision in Progress: 

  • A 30-day comment period closed on March 19, 2021. Green Seal is now reviewing stakeholder input. Details on the proposed revision to this standard can be found on the Standard Revisions page.

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.

CRITERIA THAT HELP PRESERVE THE CLIMATE

Many of the standards for human health and minimizing waste also help preserve the climate:

  • Content limits on volatile organic compounts (VOCs)
  • Prohibition on ozone-depleting compounds
  • Prohibition on halogenated solvents
  • Reduced/recycled packaging
