This makes it ideal for use in buildings where SPF is present and needs to be separated from the interior by a fire-resistant barrier.
The paint has excellent bonding characteristics and will adhere to most sound, clean, foam surfaces. It is important to ensure that the surface is properly prepared before applying DC315, as the quality of the application depends on the surface preparation. The foam surface should be clean, cured, firm, dry, and free of any contaminants such as dust, dirt, oil, or grease. Any defects, such as gouges, holes, or exposed cells, should be repaired prior to painting.
DC315 can also be tinted with up to 1 ounce per gallon of standard tints, and a topcoat can be applied for a higher architectural finish without negatively impacting its performance. However, it is important to verify the suitability of the topcoat for the specific application with the manufacturer before installation. Additionally, DC315 has been tested for 1-hour fire resistance in certain wall or floor assemblies, and its thickness can be adjusted to meet specific rating requirements.
Overall, DC315 is a reliable and effective fireproof paint designed specifically for spray polyurethane foam, providing a cost-efficient and internationally approved solution for fire protection in building applications.

It can be applied by brush, roller, or airless sprayer
DC315 is a fireproof paint that can be applied by brush, roller, or airless sprayer. It is designed for use on thermosetting (non-melting) type plastics like spray polyurethane foam. While it is possible to apply DC315 by brush or roller, using an airless sprayer is recommended to achieve a more consistent mil thickness.
Before applying DC315, it is important to ensure that the surface is clean, cured, firm, dry, and free of any dust, dirt, oil, wax, grease, mildew, or efflorescence. The foam surface should have a slight profile or texture similar to an orange peel for better adhesion. Smooth or glossy foam surfaces should be flash-coated with a light 3-4 mils Wet Film Thickness (WFT) of DC315 before the full application.
When applying DC315 with an airless sprayer, it is suggested to test a pre-measured area to get a feel for spraying and yield. For example, if you require 20 wet mils or 80 sq. ft. per gallon, a 5-gallon pail would be sufficient for 400 sq. ft. Outline the desired area with tape, thumbtacks, or canned spray paint, and spray inside the outlined area. Take wet film thickness measurements with a wet film gauge to understand the maximum yield.
In areas where an airless sprayer is not practical, such as around pipes and air ducts, DC315 can be applied by brush or roller. Flash coating, which involves a quick burst of DC315 or a primer, is recommended for these areas. It is important to wait at least one hour after spraying SPF before applying DC315 to ensure proper adhesion.
Additionally, DC315 can be tinted with up to 1 ounce of standard tints per gallon. A topcoat can also be applied over DC315, such as an interior water-based vinyl/acrylic like Sherwin Williams A-100 or Promar 400. The use of a topcoat can enhance the architectural finish and will not negatively impact the performance of the coating. However, it is essential to verify the suitability of the topcoat for the specific end-use application with the manufacturer before installation.
