FOREWORD

Edition. Edition 3.2 was issued on October 26, 2015. It replaces Edition 3.1 of GS-11 and

Edition 1.1 of GS-47, both from July 12, 2013. Corrections and/or clarifications were last made to this edition on January 29, 2021. Information on standard revisions and corrections and clarifications can be found on Green Seal’s website.1

General. The final issued standard was developed in an open and transparent process with stakeholder input that included 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. 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.

GREEN SEAL STANDARD FOR

PAINTS, COATINGS, STAINS, AND SEALERS, GS-11

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; anti-corrosive coatings, including rust-preventative 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,2 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.3 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 described in the standard that appear in italics have a corresponding definition located in the definition section of the standard, Annex A.

2 i.e., floor 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.

3 Green Seal has not conducted a comprehensive review of the chemistry, health and environmental effects, and performance of anti-graffiti coatings. These product categories may be addressed in a future revision of this standard.

3.4.1 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”.22

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

19 Note that Low-Solids Coatings have a separate VOC limit, and also that their VOC content is calculated differently.

20 i.e., 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) 21 CARB 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).

22 as defined in SCM, 2007, Subsection 4.66.

OCTOBER 26, 2015 PAINTS, COATINGS, STAINS, & SEALERS, GS-11 22

VOCs for Low-Solids Coatings: For Low-Solids Coatings, the VOC content of the product shall be calculated according to “VOC Actual”.23

Where:

VOC Actual = grams of VOC per liter of coating (also known as “Material 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

Exempt compounds shall be those defined as such by the U.S. EPA.24

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.

3.4.2 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 percent 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.

23 as defined in SCM, 2007, Subsection 4.64.

24 According to the definition of VOCs in this standard, exempt compounds are considered those listed by the EPA in 40 CFR §51.100 (s). The current version of this regulation can be found at http://www.ecfr.gov/cgi-bin/text-idx?SID=049f1f9562e072c158ad6e4a47d076a2&node=pt40.2.51&rgn=div5#se40.2.51_1100 http://www.ecfr.gov/cgi-bin/text-idx?SID=049f1f9562e072c158ad6e4a47d076a2&node=pt40.2.51&rgn=div5#se40.2.51_1100 http://www.ecfr.gov/cgi-bin/text-idx?SID=049f1f9562e072c158ad6e4a47d076a2&node=pt40.2.51&rgn=div5#se40.2.51_1100
