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.

NC-2009 IEQc4.2:Low-Emitting Materials—Paints and Coatings

Tile Grout Sealer

It seems like ceramic tile grout sealer should be considered as a "Waterproofing Concrete/Masonry Sealer" with a VOC limit of 400g/L The grout is a cement product. Would not want to find out after submittal to GBCI that they consider it under "Sealers and Undercoaters" with a VOC limit of 200 g/L. Has anyone had experience submitting this as a "Waterproofing Concrete/Masonry Sealer"?

Eric, I wouldn't know for sure, but since grout is not a Division 4 product, I would not consider it a "waterproofing concrete/masonry sealer". Good Luck
