Architectural paints and coatings list VOC limits of 50 g/L for flats, and 150 g/L for non-flats - however, these limits specify application at walls and ceilings. Layout lines and markings applied to resilient athletic flooring often include graphics and lettering; the South Coast Air Quality Management District (SCAQMD) Rule 1113 defines Graphic Arts Coatings as "coatings formulated for hand-application by artists using brush or roller techniques to indoor and outdoor signs (excluding structural components) and murals, including lettering enamels, poster colors, copy blockers, and bulleting enamels." Graphic Arts Coatings carries a VOC limit of 500g/L. As indicated above, paints applied to resilient athletic floors do not meet the VOC limits for paint as specified in the credit requirements, however, they are compliant with VOC limits of Graphic Arts Coatings as specified by SCAQMD Rule 1113. Please clarify if roller or brush-applied paint for layout lines and markings would be classified as Graphic Arts Coatings, under SCAQMD rule 1113. If not, please advise how to otherwise achieve the credit requirements. Additionally, graphics applied to textured resilient athletic flooring require air-brushing layout lines and markings; the South Coast Air Quality Management District (SCAQMD) Rule 1113 defines Aerosol Coating Products as "pressurized coating product containing pigments or resins that dispenses product ingredients by means of a propellant, and is packaged in a disposable can for hand-held application, or for use in specialized equipment for ground marking and traffic marking applications." VOC limits for Aerosol Coating Products are excluded from Green Seal Standard GS-11, and the South Coast Air Quality Management District rule 1113. The USGBC also ruled on 02/10/2009 that Aerosol Coating Products are excluded from EQc4.2. As paint for floor graphics is loaded into a compressor, and applied using air as the propellant, please clarify if this would be deemed an Aerosol Coating Product, and therefore excluded from this credit. If not, please advise how to otherwise achieve the credit requirements.
The project team is seeking clarification on the applicable standards for paint used for layout lines and markings on athletic flooring. For any roller or brush-applied paint, the proposed reference standard, Graphic Arts Coating for SCAQMD rule 1113 appears to be the appropriate standard for this application. Similarly, when the paint is applied using a compressor and propellant, it would meet the definition of an aerosol coating product, per the same rule. Applicable Internationally.
