Green Seal recently released a revised version of its GS-11 Standard that covers most types of architectural coatings available on the market today. The new standard is a compilation of the previous GS-11 version and the GS-47 Standard for Stains and Finishes.
GS-11 includes floor coatings, concrete and masonry sealers, and fire-resistant coatings, as well as the paints, primers, anti-corrosive coatings and reflective coatings covered by previous versions. Clear and transparent coatings also are included in the 24 product categories that now are eligible for certification.
The standard offers greater flexibility for the assessment of VOCs and aligns with VOC limits set by the current California Air Resources Board. In addition, the standard addresses stains and finishes for wood and metal, which previously was covered by the GS-47 Standard, and clarifications on certain criteria for chemical ingredients.
Because formulation technology is advancing rapidly, Green Seal redesigned GS-11 to promote the creation of safer coatings by restricting many harmful chemicals, including heavy metals, certain phthalates, formaldehyde donors, carcinogens, mutagens, reproductive toxins, hazardous air pollutants 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 don’t exist.
