Green Seal GS-11 and GC-03 do not address stains, lacquers, varnishes, sealers and paint applied by aerosol cans. For an interior application, what if any, requirements for VOC and chemical content should these products meet? Are they exempt? Even though many materials requiring these products can be finished off site, there is still a need for field application and touch-up for a small percentage of surfaces. Is this interior touch-up and/or application of coatings that do not meet Green Seal or ARB addressed by "Calculations", p. 247, LEED Reference Package, Version 2? If so, are only paint and carpet VOC to be addressed in the building budget?
Aerosol paint applications are highly volatile and difficult to control. Using these products on-site is bound to add significant doses of VOC to the building, and should be avoided as much as possible. Typically, on site aerosol touch-up is used to address unanticipated damage that occurs during construction. It would be prudent to address this issue within the construction IAQ credit, since touch-up paint is so difficult to control by specification. Because touch-up is unanticipated and represents a tiny fraction of paint and coating application, it is difficult to see how this could be included in the VOC calculations. Application of coatings is a different matter, and implies that the design intent specified an aerosol application for a specific surface. In this case the paint or coating should definitely be included in the VOC calculations, and steps should be taken to specify a low VOC paint or coating. Applicable Internationally.
