GS-11 allow primers to have a VOC content limit of 100 g/L. Other references group 'Paints, Coatings and Primers' together and limit the VOC content based on flat (50 g/L) or non-flat (150 g/L) finish.

Please advise what is the correct VOC limit for flat primers.

And is there any difference under LEED for Schools 2007?
