Interior finishes - Plywood

When can plywood be used as an interior finish?

The Joint Commission uses NFPA 101-2012, Life Safety Code where 19.3.3.2 allows for non-treated plywood (Class C) in existing installations if the space is sprinklered and separated from the exit access corridor. New installations, whether in new health care occupancies or new installations in existing health care occupancies, in unoccupied spaces such as information technology equipment closets are to use fire-retardant-treated (FRT) plywood (Class A). Both instances can be painted. The substrate is the primary driver for the finish class, not its cover (paint). The paint supplier should be consulted to validate the paint used is compatible with the application to achieve the desired finish class. For example, latex paint, being water-based, has a low flame spread rating once dried. At least one label should be kept visible if FRT plywood is used.
