Karnak - 97 Fibered Aluminum Roof Coating, 1 Gallon

Karnak 97 Fibered Aluminum Roof Coating (1-Gallon) is a reflective, fiber-reinforced asphalt coating designed to protect roofing surfaces from heat, UV, and weathering. Engineered for smaller repair jobs or detailed touch-ups, the 1-gallon size offers easy handling while delivering the same high-performance formula. The aluminum finish reflects solar energy, helping extend roof life while enhancing energy efficiency, especially on aged asphalt-based systems.

Key Features

• Reflective aluminum pigments create a durable metallic barrier against UV and heat
• Reflects over 50% of solar radiation, preserving asphalt oils and reducing roof temperature
• Reinforced with fibers for added durability and crack resistance
• Helps extend roof life and improve energy efficiency
• UL Class A fire rating over specific modified bitumen systems

• Clean the roof surface thoroughly, removing dust, dirt, oil, and loose material.
• Repair cracks or blisters with Karnak flashing cement and embed reinforcing fabric where necessary.
• Allow new asphalt roofs to weather at least 90 days before coating. Cured emulsions should set for 3–5 days. Severely aged roofs may require priming with Karnak 100 Non-Fibered or 220 Fibered Emulsion.
• Mix the coating thoroughly by mechanical means before application.
• Apply evenly using a soft roof brush, roller, or spray at 1–1.5 gallons per 100 sq ft. Avoid over-brushing to maintain aluminum leafing.
• Allow coating to cure for 24–48 hours before exposure to moisture. Ensure proper ventilation and avoid open flames.

Q: What type of protection does this coating provide?
A: It reflects more than 50% of solar energy, helping to protect roof materials from UV and heat damage while reducing interior temperatures.

Q: What surfaces can it be used on?
A: It can be applied to modified bitumen, aged asphalt roofs, metal, and properly cured emulsion-coated surfaces.

Q: How much area does a gallon cover?
A: One gallon covers approximately 100 sq ft at 16–24 wet mils (1–1.5 gallons per 100 sq ft).

Q: Do I need to repair or reinforce areas before application?
A: Yes. Cracks, seams, and blisters should be repaired with flashing cement and reinforcing fabric for best performance.

Q: Does it meet recognized standards?
A: Yes. It complies with ASTM D-2824 Type III, ASTM D-3805, TT-C-498C, and carries a UL Class A fire rating on approved systems.
