Is cork plank flooring a hard surface flooring requiring FloorScore certification? I do not see it specifically listed as a "hard surface" nor do I see it excluded.

The reference manual reflects a separate requirement for "concrete, wood, bamboo and cork flooring" sealers to meet the SCAQMD requirements, much as grout and mortar are listed separate. However, mineral-based flooring is explicitly excluded while cork is not unless it is considered a solid wood?
