We have this Bitumen Primer material applied on site. The contractor submitted it's data sheet but no VOC content was mentioned. We're asking them for the VOC test certification but they are having trouble to provide it since currently in our country, no testing laboratories can cater the testing for it (Bitumen Primer). The material is a combination of oil bitumen and selected organic solvents and was applied at the ramp slab of the building. Any thoughts on this?
