How to Apply
NEW BLACK DC 315 is an intumescent coating applied over Spray Polyurethane Foam (SPF) to achieve a “15 Minute Alternative to Thermal Barrier” and “5 Minute Ignition Barrier.” DC315 is compliant to IBC & IRC codes; 3rd party inspected and listed by Warnock Hersey ( WN-20947), and meets the requirements of the AC456 criteria recently updated in AC377. DC315 has more than 200 tests worldwide over a wide variety of foams. It has one of the best coverage rates for foam at 115 sq ft/gallon, making it very cost efficient.
The new BLACK color is perfect for ceilings that you want to visually recede, especially theaters and churches, or areas that get very dirty.

Prior to Applying DC 315 to Ensure Proper Adhesion: Adhesion of a coating to SPF requires the foam surface to have a slight profile or texture similar to an orange peel (view below). Smooth or glossy foam surfaces should be flash coated with a light 3 - 4 mils Wet Film Thickness (WFT) of DC 315 before applying the full application. Flash coating is a quick burst of DC 315 or a primer via airless sprayer over an area needing treatment. We also recommend flash coating around all pipes and air ducts.
Wait minimum of one hour after spraying SPF before applying DC 315.
Surface Preparation: All surfaces to be coated must be clean, cured, firm, dry and free of dust, dirt, oil, wax, grease, mildew, and efflorescence. The quality of any application is only as good as the surface preparation that precedes the application. Our coating has excellent bonding characteristics and will adhere to most sound, clean, foam surfaces. Verify that the surface of the foam is free of gouges, holes, and exposed cells. Also verify the surface is stable, and not crumbling or deteriorated. If any such defects are found make sure to repair them prior to proceeding.
Material Preparation: DC 315 must be thoroughly mixed before application. Failure to do so will seriously compromise the coating’s ability to perform. It is recommended to perform mechanical stirring with a high speed drill and a paddle appropriate for the size container you are working from. Contents should be stirred from the bottom up making sure to scrape the bottom and sides with a paint stick as you go. Contents should be stirred to a creamy consistency with no lumps. Continue mixing for 4-5 minutes per 5 gallon pail. Thinning is usually not needed. If DC 315 has been exposed to high heat, water may evaporate from the plastic 5 gallon container. If the paint level is below 3 inches from the top of the container, add enough water to bring the level back up to within 3 inches from the top in order to ensure proper consistency.
DC 315 Viscosity: DC 315 is a 9,000-10,000 viscosity coating. When you open a container of DC 315 it may appear thick before it is mixed, but once remixed for 5 minutes it will return to 9000-10,000 viscosity.
Application Equipment: DC 315 is best applied with an airless sprayer to achieve a more consistent mil thickness. In challenging areas where an airless sprayer is not practical, DC 315 can be applied by brush or roller Spraying DC 315 for Maximum Yield: If this is the first time using DC 315 we suggest testing a pre-measured area to get a feel for spraying and yield. Example, if the job requires 20 wet mils or 80 sq. ft. per gallon, then a 5 gallon pail would cover 400 sq. ft. Measure out one or two 400 sq. ft. sections using pieces of tape, thumbtacks, or canned spray paint. Use just enough to outline the area you intend to apply DC 315. We suggest spraying inside the outlined area and taking wet film thickness measurements, with a wet film gauge across the area, to get a feel for maximum yield.
Coverage rate averages between 73-115 sq ft per gallon, depending on foam manufacturer. Call us for exact numbers.
