We are using a resinous flooring system in some restrooms. It does not seem to meet the Green Seal definintion of "Coating" since it includes aggregate and color chips. So I don't think it falls in 4.2 - Paints & Coatings, but I'm not sure if it fits any of the categories for 4.3 - Flooring Systems either. Do you have any experience or insight with this type of product? Thanks.
