What is the VOC limit for a Terrazzo Sealer? I'm a bit confused about which category it falls under (Sealer, Floor Coating, or other). Owner would prefer a high sheen product but wants to comply with LEED requirements. Any guidance would be appreciated.

100 g/L is the IEQ 4.2 threshold. Many available products but the question is what performs best for the specific application. Acrylic, Epoxy, Urethane..... I'd get the facilities manager and applicator to give some guidance.

Thank you Bruce for the information. One more question: the contractor wants to see specific documentation with the VOC requirement. Are you referencing the "Primers, Sealers, and Undercoaters" 100 g/L requirement in the SCAQMD Rule 1113 chart? I want to make sure the documentation I send over is accurate. Thank you very much for the assistance.

Todd, 1113 identifies Floor Coatings as those applied to, among other things, concrete floors which terrazzo certainly is. Primers, sealer and undercoaters are defined more for their ability to promote adhesion to the substrate. Clearly, this is one of those areas where interpretations may be different. However, the USGBC has accepted the Floor Coating definition for terrazzo sealers on several projects I've done. Good luck!

Tood, I incorrectly asumed you're inquiring about cement terrazzo. Even if it epoxy terrazzo the floor coating reference would be correct but not sure why an epoxy terrazzo would need a sealer applied.

All of our epoxy terrazzo submittals come in with a required sealer. Since sealers are 200 g/L, we've allowed them up to that limit. All other portions of the terrazzo need to be below 100 g/L. I think of it like top shield for linoleum.
