Guidelines for Prevention of Mold Growth on Gypsum Board – GA-238-2025 (PDF Download)

However, mold spores are present everywhere, and when conditions are favorable, mold can grow on practically any surface. Observation of these guidelines will help minimize the potential for mold growth on gypsum board.
