GS-11
Paints, Coatings, Stains, And Sealers
Upcoming Revision: In 2020, Green Seal committed to a multi-year phased approach for restricting per- and polyfluoroalkyl substances (PFAS) in all certified products due to their adverse health and environmental impacts. We completed Phase I in 2022 by prohibiting PFAS in formulas for certified cleaning and personal care products. Now, in the second phase of this initiative, Green Seal is proposing criteria to prohibit PFAS in this standard. To learn more or receive project updates, visit our Standard Projects page.
Our 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.

FOREWORD
Edition. Edition 4.0 was issued on September 7, 2021. It replaces Edition 3.2 from October 26, 2015. Corrections and/or clarifications were last made to this standard on August 23, 2024. Information on changes made to this standard are available on Green Seal’s website.1https://greenseal.org/green-seal-standards/library#section5
General. The final issued standard was developed in an open and transparent process involving a balanced group of stakeholders including producers, users, and general interests.
The requirements in the standard are based on an assessment of the environmental, health, or social impacts associated with the products covered in the scope of the standard. These requirements are subject to revision and generally cover aspects above and beyond regulatory compliance. This standard neither modifies nor supersedes laws and regulations. Any conformity assessment to this standard requires compliance with all applicable laws and regulations for the manufacturing and marketing of the products.
Provisions for safety have not been included in this standard, since they are overseen by regulatory agencies. Adequate safeguards for personnel and property should be employed for all stages of production and for all tests that involve safety considerations.
Products that are substantially similar to those covered by this standard in terms of function and life cycle considerations may be evaluated against the intent of the requirements of this standard, accounting for relevant differences between the intended scope of the standard and the actual product to be evaluated.
This standard may not anticipate a feature of the product that may significantly, and undesirably, increase its impact on the environment, health, or society. In such a situation, Green Seal will ordinarily amend a standard to account for the unanticipated environmental, health, or societal impacts.
Normative references (e.g., other standards) in this standard intend to refer to the most recent edition of the normative reference unless explicitly stated otherwise. Test methods may be required for product evaluation. Unless explicitly stated that a specified method is the only acceptable one, the intent of the standard is that an equivalent test method may be accepted at Green Seal’s sole discretion. Certification to this standard shall be awarded only by Green Seal or, with Green Seal’s explicit written permission, by a third-party certification program conducting on-site audits.
Disclaimer of Liability. Green Seal, as the developer of this standard, shall not incur any obligations or liability for any loss or damages, including, without limitation, indirect, consequential, special, or incidental damages, arising out of or in connection with the interpretation or adoption of, reliance upon, or any other use of this standard by any party. Green Seal makes no express or implied warranty of merchantability or fitness for a particular purpose, nor any other express or implied warranty with respect to this standard.

1.0 SCOPE
This standard establishes environmental, health, and performance requirements for certain architectural coatings that are intended to be applied on-site, and for stains, finishes, and sealers.
The standard covers the following product categories for interior and exterior architectural use: wall and ceiling coatings, including paints and reflective wall coatings; anticorrosive coatings, including rust-preventive coatings; floor paints; primers (undercoats); stains; finishes; and sealers, including concrete and masonry sealers (both penetrating and film-forming products) for interior and exterior use and basement specialty coatings for interior use. The standard also covers floor coatings intended for general purposes in commercial and residential settings,2Floor coatings that are not intended for resistance in challenging environments, such as acid/base/corrosive surroundings or extreme temperatures. General purposes may include shopping centers, airport lobbies, grocery stores, office buildings, homes, and garages. as well as fire-resistive coatings, including intumescent coatings for interior architectural use and reflective roof coatings for exterior architectural use.
The standard includes products intended to be applied to wallboard, tile, metal, wood, composite wood, concrete, stone, masonry, and terrazzo substrates, as well as other architectural substrates. Also included are stains, finishes, and sealers generally applied to non-architectural metal and wood substrates.
All product categories may be clear, transparent, or opaque.
The standard does not include recycled (consolidated or reprocessed) latex paint, floor finishes/polishes intended to be stripped and reapplied periodically, specialty non-architectural coatings (e.g., coatings for industrial equipment, marine or automotive use), products sold in aerosol cans, or anti-graffiti coatings.3Green Seal has not conducted a comprehensive review of the chemistry, health, and environmental effects or the performance of anti-graffiti coatings. These product categories may be addressed in a future revision of this standard.[/fn] The standard is not intended to define leadership criteria for industrial maintenance coatings, intended for resistance in challenging environments, such as acid/base/corrosive surroundings or extreme temperatures. However, products that are labeled as industrial maintenance coatings may be certified to this standard if they meet all the criteria for the product category whose function most closely aligns with them.
See Appendix 1 for a sample list of products that are or are not included in this standard.
Words and phrases that appear in italics are defined in Annex A.
2.0 SAFER CHEMICALS
All requirements pertain to the product produced by the manufacturer and do not include additives introduced at the point-of-sale, unless otherwise specified.
2.1 Safer Ingredients
2.1.1 Carcinogens, Mutagens, and Reproductive Toxins. The product shall not contain any ingredients that are carcinogens, mutagens, or reproductive toxins.
Exemption: An exception shall be made for titanium dioxide and, for products that are pre-tinted by the manufacturer, carbon black. As allowed under this exception, carbon black shall be less than or equal to 1% by weight of the product.4Titanium dioxide: EC Number 236-675-5, CAS Number 13463-67-7; carbon black: EC Number 215-609-9, CAS Number 1333-86-4.

Exemption: For lacquers intended for metal substrates only, PCBTF (parachlorobenzotrifluoride, CAS# 98-56-6), a halogenated organic solvent, is allowed at levels that do not exceed 10% by weight in the product.
2.1.4 Volatile Aromatic Hydrocarbons. The product shall contain no more than 0.5% by weight of sum total of volatile aromatic hydrocarbons.10Testing for the concentration of these compounds will be performed if they are determined to be present in the product during a materials audit.
2.2 Safer Products
2.2.1 Volatile Organic Compounds (VOCs) Content Limits. The VOC content of the product shall not exceed the content limits for its product category as set by CARB Suggested Control Measure for Architectural Coatings (2007).11See Appendix 2 for the VOC limits specified in California Air Resources Board Suggested Control Measure for Architectural Coatings (2007).
Exception: For low-solids coatings, the CARB VOC limit for low-solids coatings shall apply instead of the VOC limit that would otherwise apply for the product category (as mandated by CARB).12Note that low-solids coatings have a separate VOC limit and that their VOC content is calculated differently.
Exception: Products labeled as industrial maintenance coatings shall meet the VOC limits for their relevant product category.13That is, they will not be allowed to meet the higher VOC limits set by CARB for industrial maintenance coatings. This standard is not intended to establish leadership criteria for industrial maintenance coatings per se (see Section 1.0).
Exception: Products sold in containers equal to or smaller than 1 liter are not exempted from the VOC content limit for their product category (even though exempted by CARB).14CARB currently grants an exemption from VOC limits to products sold in containers equal to or smaller than 1 liter (known as the Small Container Exemption).
For other product categories not regulated by CARB, the VOC level shall not exceed a limit set by CARB for a similar product category. If no CARB category, or similar CARB product category exists, the VOC limit shall not exceed the limit for the applicable product category in the South Coast Air Quality Management District (SCAQMD) Rule 1113, effective June 3, 2011.
2.2.1.1 Calculation of VOC Content.
Coating VOC: For all product categories except low-solids coatings, the VOC content of the product shall be calculated according to “VOC Regulatory,”15As defined in SCM, 2007, Subsection 4.66.
Where:
VOC Regulatory = grams of VOC per liter of coating, less water and exempt compounds (also known as “Coating VOC”)
Ws = weight of volatiles, in grams
Ww = weight of water, in grams
Wec = weight of exempt compounds, in grams
Vm = volume of coating, in liters
Vw = volume of water, in liters
Vec = volume of exempt compounds, in liters
VOCs for Low-Solids Coatings: For low-solids coatings, the VOC content of the product shall be calculated according to “VOC Actual,”16As defined in SCM, 2007, Subsection 4.64.
Where:
VOC Actual = grams of VOC per liter of coating (also known as “Material VOC”)
VOC content shall exclude colorants added at the point-of-sale and any VOCs generated as a result of chemical or curing reactions on-site.
For multi-component products, VOC content shall be determined based on the sum of all components added together, using the appropriate calculation.
2.2.1.2 Methods for Determining VOCs. The VOC content shall be determined in one of the following ways for compounds present in the product at 0.01% or more:
Product Formulation By summing the percentage by weight contribution from all VOC ingredients listed in the formulation of the product, and which have a boiling point of less than or equal to 280°C at 1 standard atmosphere (101.3 kPa).
Mass Difference Methods According to EPA Method 24, ASTM D2369, SCAQMD Method 304, or ISO 11890-1 (or equivalent), modified to include all VOC ingredients.
GC/MS Methods According to ASTM D6886, SCAQMD Method 313, or ISO 11890-2 (or equivalent), summing all those VOC ingredients that have a boiling point of less than or equal to 280°C at 1 standard atmosphere (101.3 kPa).
Another scientifically validated test method may be used if it is justified and documented in sufficient detail.
2.2.2 VOCs of Colorant Added at Point-of-Sale. The VOC concentration of the product including the colorant added at the point-of-sale shall not exceed 50 grams of VOC per liter of product above the levels allowed for the product without colorant.18VOC limits and measurement methods for the products are specified in Section 2.2.1.
An average VOC level calculation for a colorant shall be applied unless a manufacturer can provide documentation of the VOC levels of the colorant(s) and assurance that only those colorant(s) tested shall be used with the product.19If information is not available about the VOC content in the colorants, an average of 70 grams/liter from the colorant will be added to the VOC content of the base paint product, for each paint type (flat, nonflat, primer, etc.).
2.2.3 VOCs Emissions Evaluation. Products intended for interior application shall be tested according to, and meet the emissions limits20See Appendix 3 for the maximum allowable concentrations, specified in the CDPH Standard Method v1.2. specified in, the California Department of Public Health (CDPH) Standard Method v1.2 (2017).21https://www.cdph.ca.gov/Programs/CCDPHP/DEODC/EHLB/IAQ/CDPH%20Document%20Library/CDPH-IAQ_StandardMethod_V1_2_2017_ADA.pdf. As specified within the CDPH Standard Method, product specimens must undergo testing for the full 14-day (336-hour) period.
Products marketed for use in school classrooms must be evaluated using the classroom scenario. Products marketed for use in other spaces must be evaluated using the default private office scenario.
Laboratories that conduct the tests must be accredited under ISO/IEC 17025 for the test methods they use.
Note: See Appendix 3 for CDPH v1.2 emissions limits.
