Karnak Roofing 220 Fibered Emulsion Coating

KARNAK 220 Fibered Emulsion is manufactured with refined asphalt, bentonite clay, emulsifiers and fibers for brush or spray application on BUR roofs, modified bitumen membrane roofs, metal and concrete roof surfaces. The dried film cures to a tough, flexible, durable finish and will resist variations in temperature and weather. KARNAK 220 Fibered Emulsion will not burn or support combustion in a liquid state. This is a low odor coating. This coating is a “dead- level” type coating that resists the absorption of exterior moisture.

Surface Preparations

All surfaces should be clean, dry, and free from oil, grease, dust, dirt, loose paint or other foreign matter prior to application. Recommended application temperature is 40°F to 120°F. Repair all blisters, breaks and cracks with 19 Ultra Rubberized Flashing Cement and 31 Fiberglass Membrane or 34 Asphalt Saturated Cotton Fabric.

Application

220 Fibered Emulsion Coating is easily applied by brush or spray equipment. Apply 220 Fibered Emulsion Coating in one coat. If applying two coats, allow the first coat to dry. Coating should be continuous and free of pinholes and holidays. Cover all slots, joints and grooves and apply into all chases and corners. BRUSH APPLICATION 220 Fibered Emulsion Coating is easily applied with a wide fiber roof brush using wide even strokes, flowing the coating on the surface to obtain a smooth and uniform film. Make sure to brush into all cracks and crevices. SPRAY APPLICATION 220 Fibered Emulsion Coating may be easily and efficiently spray applied on large areas with a standard heavy-duty airless spray unit. Utilize a standard heavy-duty airless spray pump using heavy duty guns and nozzles. Equipment manufacturer should be consulted for more complete information

Coverage Rate

Apply at 4 gallons per 100 sq. ft. (64 wet mils) which will provide adequate protection for most surfaces. Spray application should be at the same rate.
