In addition, this chemistry has a very low VOC level (under 190 grams per liter) and very low odor, both making it easy to apply with minimal impact on workers and building occupants. Once the final coat is applied, the floor can be opened to foot traffic in 24 hours and put back in full use in 72 hours under normal conditions.
