FAQs about IEQc4.1:
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?

Do grout and caulking need to be included, and if so, what is the application category?
cut and paste from an article here within Leeduser - Yes, grout and caulking need to be included. There is no specific category for them, however. Projects have successfully used ceramic tile adhesive—VOC limit 65g/l—and Architectural Sealant—VOC limit 250 g/l—successfully, the latter being especially appropriate if you are using a product other than ceramic tiles. Since most mortars, grouts, and thinsets are largely cementitious, with inherently low VOC content, they will comply under most categories, anyway. Choose a logical category and explain it in a narrative if necessary.

I thought I remembered reading somewhere either in LEED ref. guide or an addenda or CIR to use 65 (g/l) as ceramic tile adhesive for grouts /caulks etc. Keep in mind the Rule for Arch. coatings for waterproofing used under tile.
