Just noticed this line while reading the reference guide for the 10,000th time and it may have been overlooked by me previously, looking for any other thoughts/experiences/suggestions.

Under "Changes from LEED 2009" it states that "emissions requirements for on-site, wet-applied, full-spread products ... are now included. VOC content limits for on-site, wet-applied products are still required"

This implies to me that "non-full" spread interior on-site, wet-applied products, may have been exempt from the General Emissions evaluation criteria. What is the definitition of "full spread" products? Pipe sealants for example?

A search for any other references to "full spread" products didn't turn up anything except in Table 5 of Option 2 calculation guidance which also mentioned that only full spread adhesives and grout for flooring would be included.

I understand this topic has been discussed one too many times, but it seems that at one stage, there was intent to only include the VOC emissions criteria for products where it would make a large impact such as full surface paints and coatings. Not necessarily small quantity adhesives that are spot applied and would not affect the overall IAQ. Perhaps that is what the 90% threshold is allowing for, but that still requires much more detailed documentation and calculations to track overall volume.
