The new Green Seal standard offers greater flexibility for the assessment of VOCs and aligns with VOC limits set by the current California Air Resources Board. The standard also addresses:  stains and finishes for wood and metal, previously covered by the GS-47 Standard, and updates for clarity on certain criteria for chemical ingredients, reflecting the current market for leadership products.

GS-11 ensures that certified paints, coatings, stains and sealers deliver satisfactory performance. Each product is tested for performance parameters applicable to the intended use of that product.

With the rapid advances in formulation technology, Green Seal redesigned GS-11 to promote the creation of safer coatings by restricting a comprehensive list of harmful chemicals, including heavy metals, certain phthalates, formaldehyde donors, carcinogens, mutagens, reproductive toxins, hazardous air products, and ozone-depleting compounds. Certain exceptions are made for titanium dioxide, carbon black, crystalline silica, and PCBTF because they are necessary for acceptable performance and feasible alternatives are currently lacking.

Green Seal’s certification process involves an in-depth review of product data and manufacturing procedures, including an on-site audit of manufacturing facilities. Periodic monitoring is required to maintain certification.
