220AF Fibered Emulsion Coating
Karnak #220AF Emulsion Roof Coating is manufactured with refined asphalt, bentonite clay, emulsifiers and fibers for brush or spray application on smooth surface and metal roofs. The dried film cures to a tough, flexible, durable finish and will resist variations in temperature and weather. Karnak #220AF Emulsion Roof Coating will not burn or support combustion in a liquid state. It has no odor or fumes, and resists the absorption of exterior moisture. Karnak #220AF Emulsion Roof coating can be applied to slightly damp surfaces.
Karnak #220AF Emulsion Roof Coating may be used as a coating, primer or in place of Karnak #78AF Cold Process Cement (Solvent Base) in Karnak Poly-Mastic Cold Process Systems P21 and P22.
- ASTM D-1227 Type II, Class 1
- SS-R-1781 (except -free)
- MIL-R-3472A (except -free)
All roof areas shall be clean and free of dirt, dust or loose particles. Repair all blisters, breaks and cracks with Karnak 19 ULTRA Rubberized Flashing Cement and Karnak #34 Asphalt Saturated Cotton Fabric or Karnak #31 Fiberglass Membrane. Coating must be dry before exposure to water.
BRUSH APPLICATION: Karnak #220AF Emulsion Roof Coating is easily applied with a wide fiber brush with even strokes, flowing the coating on the surface to obtain a smooth, uniform film at the rate of 4 gallons per 100 sq. ft. which will provide adequate protection for most surfaces.
SPRAY APPLICATION: The Karnak #220AF Emulsion Roof Coating is easily and efficiently spray applied on large areas with the standard mastic pump-type equipment at the rate of 4 gallons per 100 sq. ft.
Apply at the rate of 4 gallons per 100 sq. ft. When used as a primer apply at a rate of 2-4 gallons per 100 sq.ft.
Do not apply when rain is imminent. Protect from freezing. Coating must be dried before exposure to water. Store in a heated room and keep container covered when not in use. Do not thin. Avoid prolonged contact with skin. Dispose of in an environmentally safe manner.
CARE OF TOOLS
Tools and other equipment should be thoroughly cleaned with mineral spirits, taking necessary precautions when handling combustible materials.
COLD-PROCESS SYSTEMS AND COATINGS, EITHER EMULSION OR SOLVENT BASED, SHOULD ONLY BE INSTALLED ON DECKS WITH POSITIVE DRAINAGE.
PER NRCA, (NATIONAL ROOFING CONTRACTORS ASSOCIATION) "THE CRITERIA FOR JUDGING PROPER SLOPE FOR DRAINAGE IS THAT THERE BE NO EVIDENCE OF STANDING WATER ON THE DECK 48 HOURS AFTER IT STOPS RAINING."
CARE OF TOOLS
Tools and other equipment should be cleaned with water immediately after use. Dried coating may be cleaned with mineral spirits, taking necessary precautions when handling combustible materials.
Available in 5 gallon pails and 55 gallon drums.
