Does anyone know whether the waterproofing sealer used under the raised flooring to protect concrete slab needs to comply with VOC requirements?
Thank you in advance.

Anastasia—IEQc4.2 limits the VOC content of “paints and coatings used on the interior of the building (i.e., inside of the weatherproofing system and applied onsite).”
Your “waterproof sealer” does not appear to be part of the building’s exterior weatherproofing system. Its purpose seems to be to protect the slab from water originating above the slab, inside the building. I presume that this coating will be applied to the slab and that it will be exposed to air on the interior of the building at least until the installation of the raised flooring. Even then, many raised floor systems are designed to permit air circulation underneath.
Based upon these assumptions, this appears to be an interior coating that would be subject to IEQc4.2’s VOC limits.
