What is DC315 paint?
DC315 is an intumescent fire-retardant coating (more specifically, an intumescent coating) designed primarily for use over spray polyurethane foam (SPF). It serves as a 15-minute thermal and ignition barrier, meeting International Building Code (IBC) and International Residential Code (IRC) requirements. When exposed to high heat, DC315 expands to form a protective layer, slowing the spread of fire and increasing the safety of the building to which it is applied. It can be used as the primary base for a range of decorative, fire-retardant paints if mixed according to the manufacturer’s instructions.
How much coverage per gallon are DC315 fire-retardant paints?
DC315 provides up to 115 square feet of coverage per gallon at the recommended thickness for ceilings and walls. This allows for efficient application in both residential and commercial buildings, ensuring proper fire protection while minimizing product use.
Who manufactures DC315?
DC315 is manufactured by International Fireproof Technology, Inc. (IFTI), a company specializing in fire protection products, including intumescent coatings and fire-retardant paints.
Can you paint over DC315?
Yes, you can paint over DC315. It is compatible with a variety of topcoats, including water-based acrylics. We have tested with various protective topcoats and aesthetic topcoats. All are listed in our master specifications to meet the needs of your specific application. These topcoats do not affect the fireproofing performance of DC315, and they can be used to enhance the aesthetic finish while maintaining the fire-retardant properties.
Can DC315 be used outdoors?
No, DC315 is primarily designed for indoor use and is not recommended for outdoor applications. It is a water-based intumescent paint, and prolonged exposure to outdoor elements such as rain, extreme temperatures, and UV light can degrade its performance over time. While DC315 provides excellent fire protection for interior surfaces, it would require additional weather-resistant coatings if used outdoors or in unconditioned spaces to protect it from environmental factors. For outdoor applications, it’s essential to use a different fire-resistant coating specifically formulated for exterior use. If you need to apply DC315 in a partially exposed environment, you should consult with the manufacturer or use a topcoat to provide weather and moisture protection.
Can DC315 be applied in high humidity?
DC315 should not be applied in environments with high humidity. Specifically, it is recommended to avoid applying DC315 when the humidity is above 65%, as high humidity can interfere with the proper curing and performance of the paint. Additionally, the temperature during application and throughout the curing process should be at least 10°C (50°F) to ensure the coating cures correctly. If the humidity is too high, there’s a risk of moisture getting trapped in the coating, which could impact its effectiveness as a fire retardant. Monitoring humidity levels and ensuring proper ventilation during the application process is crucial to achieving optimal results. Review our ventilation guide for more information.
How long does DC315 take to dry?
DC315 typically takes 1 to 2 hours to dry to the touch under normal conditions, which includes a temperature of around 77°F (25°C) and relative humidity at or below 50%. If a second coat is needed, it is recommended to wait 2 to 4 hours before recoating. However, drying times can vary based on factors such as temperature, humidity, and ventilation, so be sure to monitor every application.
For best results, ensure the application environment stays within the recommended humidity and temperature levels to allow proper curing. Your product application guide will outline all the necessary information. If any questions arise, we are just a phone call or email away.
