Schools-2009 IEQc4.1: Low-Emitting Materials—Adhesives and Sealants
How should a ready mixed drywall joint compound be treated for the purposed of EQc4.1 and/or EQc4.2? Is it classified as an Architectural Sealant by SCAQMD 1168 for EQc4.1? Or would it classified as some sort of coating under EQc4.2?

Do products applied to the weather barrier need to comply with VOC thresholds?
How do I determine what application my product falls under?
How is VOC % less water determined for aerosol adhesives?
Do grout and caulking need to be included, and if so, what is the application category?

Would it be classified as a Dry Wall and Panel Adhesive? SCAQMD 1168 defines a Dry Wall Adhesive as "an adhesive used during the installation of gypsum dry wall to studs or solid surfaces." Dry wall joint compound does not seem to meet this defintion.

Alison, I would be curious to hear what others have to say but I don't think this falls under either IEQc4.1 and IEQc4.2. It is clearly not a paint or coating, and I think it would be stretch to call it an adhesive or sealant. It is really functionally more similar to the drywall itself rather than an adhesive.If anything, it would be covered under IEQc4.6: Low-Emitting Materials—Ceilings and Wall Systems, but as we discuss under IEQc4.6, it is not covered there either (although using a low-emitting product is a good idea, especially if you're doing IEQc3.2.

Not sure if anyone will see this, but I wonder if it wouldn't be classified as a Sealant under Rule 1168: (67) SEALANT is any material with adhesive properties that is formulated primarily to fill, seal, or waterproof gaps or joints between two surfaces. Sealants include sealant primers and caulks. So it should be counted under IEQc4.1?

As LEED-2009 fades into the sunset, we've been asked under D&C Final review to submit GWB joint compound under EQc4.1. 12 years on, there's still no appropriate category for it in the EQc4.1 form.... or guidance anywhere on what the allowable VOC content might be.

We include GWB joint compound under Adhesives & Sealants categorized as "Drywall and Panel Adhesives."
