Hello. In our project we have a large underground structure to house an IMAX Theater. Since we're below freatic line, we need to apply in the interior face of the concrete structure an additional water seal (actually a weatherproof product). Since the discussion in the forum I assume that as long as this product in in the interior side and touches the interior air, it need to comply with VOC requirements. But I have a question: That's required even if that there will be more products (finishes) applied over it? It will not be emitting to the air at the operational stage. Thank you.
