Application of Fireproof Paint DC315 in unconditioned spaces
Projects that are exposed to ongoing high humidity conditions require the use of a primer and topcoat. Topcoats protect the DC315 from condensation as well as provide a barrier for vapor to transfer through the coating.

DC315 is designed to be permeable to allow for proper curing of the underlying SPF. This allows DC315 to be used in all applications including those that do not require a vapor barrier. High humidity and moisture can affect the long-term adhesion. Apply the primer then DC315. Allow the DC315 to cure for a minimum of 12 hours before applying the top coat.

Ventilation is critical for proper application and curing of DC315 coating. The drying time of DC315 when applied at 18-24 Mils WFT, is longer than simply “dry to touch” and may take 48-72 hours for initial curing.

The use of space heaters is necessary in colder temperatures to ensure the application area is maintained within specified temperatures found on the application guide.

Do not use combustion source heaters, commonly referred to as “Salamanders” as these units add a significant amount of moisture as a byproduct of the combustion process. Indirect heaters or electric element forced air are ideal for maintaining temperature and aiding in the control of excess humidity. Temperatures must be maintained above 50°F (10°C) for the duration of the application and curing process.
