NC-2009 IEQc4.2:Low-Emitting Materials—Paints and Coatings

One paint / two applications / two standards?

We have a waterborne acrylic enamel that is used in two applications in our project. When applied to steel joists, conduit, etc. I understand that it would be classified as an anticorrosive / anti-rust paint, with a VOC limit of 250 g/L. It has also been proposed to be used on a concrete ceiling surface. If used in this application, it would seem to have a VOC limit of 150 g/L. Am I understanding this correctly? As it has a VOC of 180 g/L, it would seem to meet the requirements for one application but not the other.

Nereyda, I think you are understanding it correctly.The requirements for different applications vary based on the standard practices and technical requirements of those areas. What the VOC requirements are telling you here is that you can find products that do better for application to the concrete, but that this may be a decent product in the context of anti-corrosive paints.
