FAQs about IEQc4.2 :

How should graphic arts paint or coatings be categorized?

The standards referenced for this credit have been updated since those listed in the LEED Reference Guide – does our project need to follow the latest SCAQMD Rules and Green Seal editions, or the ones listed in the reference guide?

How should handheld aerosol spray paints be handled?

What are the VOC limits for primers? They seem to be listed in both GS-11 and SCAQMD Rule 1113.

Susan, there are no specific restrictions on UV-cured finishes—just the same rules as apply to all finishes.

UV-cured lacquers are often specified as shop-applied wood finishes, not so much for on-site application. Ask your subcontractor to confirm how and where they intend to apply the product. If they use it only in the shop, IEQc4.2 VOC limits will only become applicable if touch-up of damaged finishes occurs on-site. When I have specified UV-cured shop finishes, I have specified compatible non-UV, low-VOC products for field use if touch-up becomes necessary on-site.
