Hello,

I'm wondering what category I should put product used for surface primering. Normally these product are used outside, on the roof, but on my project we have to use it inside in the technical rooms.

My product has MSDS, which states that the VOC content is: 475 g/L, and theoretically SCQAMD r.1168 states that Sealant Primers Modified Bituminous have limit of 500 g/L which is fine for me, but this is typically for waterproofing on roof purposes, so all the limits from ROOFING Sealants group are lower. Moreover, the formv04 from LEEDOnline in that drop-down list doesn't have such group as Modified Bituminous Sealant Primer and I will have then problem with uploading that on LO.

Another question I have is related to tar paper. It is SBS elastomer modified product and I would like to know whether any of you know if that product emits any VOCs? I believe yes, but since it is mainly used outside nobody is actually caring about that and in my case, where we install it inside the building I have problem with obtaining any information how much VOCs this type of product can emit.

If any of you could help me I would be very grateful.
