FAQs about IEQc4.1 :

Is there a shortcut to the VOC budget method if you have just one product that is used minimally on a project?

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?

Our project didn't use some common adhesive types, and our LEED reviewer asked about this. Are we supposed to justify not using certain adhesives in our documentation?

I wonder that under which category an "acrylic concrete primer" should be evaluated. We have a Siloxane Acrylic Primer in order to use in architectural concrete walls in interior with a very high VOC value, 739 gms/lt. I doubt that this material fits in the credit. Thanks

My first comment would be, for the Health and welfare of all involved, could you research a little more to find a product with a lower VOC? That being said, under Rule 1168 Sealant Primers - Architectural -Porous limit is 775 g/l, therefore your product should be compliant.

I appreciate for your response. I also believe that it is needed to find another product with a lower VOC. Thanks
