Both Caliwel Industrial Mold and Mildew Inhibitor and Caliwel Home and Office Mold and Mildew Inhibitor are naturally flame retardant due to the hydrolized lime they contain. Both are rated zero on the Flame Spread Index and Smoke Development Index in results obtained using the ASTM E 84 standard test method for surface burning characteristics (https://www.ahfc.us/application/files...). This test is used by regulatory agencies and code officials to rate interior wall and ceiling finishes.
