BULLDOG Fiber Roof Coating #106AF

BULLDOG® Fiber Roof Coating #106AF is a black, asphalt-based, fibered roof coating designed for aged built-up asphalt roofs, metal roofs, and modified bitumen roofing systems. This ready-to-use coating helps extend the service life of compatible roof surfaces by adding a durable, elastic protective layer as part of a preventative roof maintenance program.

Formulated for dependable adhesion and long-term flexibility, BULLDOG Fiber Roof Coating #106AF is built to protect existing roof systems from continued weather exposure while helping reduce the need for more extensive repairs when applied at the right time. It requires no heating or thinning, making it a practical choice for contractors, maintenance crews, property managers, and facility teams.

What BULLDOG Fiber Roof Coating #106AF Is Used For

BULLDOG Fiber Roof Coating #106AF is used to periodically recoat built-up roofing surfaces and help preserve existing roof systems. It is especially useful when a roof is aging but still structurally sound enough to benefit from a maintenance coating. When properly applied, the coating helps resist alligatoring, checking, bubbling, running, brittleness, and cracking.

Common Applications

• Recoating aged built-up asphalt roofing systems
• Maintaining compatible metal roof surfaces
• Protecting modified bitumen roofing systems
• Supporting preventative roof maintenance programs
• Helping extend the service life of existing roof surfaces
• Dampproofing exterior below-grade masonry walls where hydrostatic pressure is not present

Key Features and Benefits

• Black, asphalt-based, fibered roof coating
• Ready to use with no heating or thinning required
• Elastic coating designed to move with compatible roof surfaces
• Adheres well to appropriate roofing substrates
• Helps resist running, brittleness, and cracking
• May help add years of service life to properly prepared roofs
• Suitable for brush, roller, or spray application
• Designed for preventative roof maintenance and roof restoration support

Recommended Surfaces

BULLDOG Fiber Roof Coating #106AF is recommended for aged built-up asphalt roofs, metal roofs, and modified bitumen roofs. Surfaces should be dry, clean, and free of dirt, loose material, and conditions that may interfere with adhesion. Cracks and problem areas should be repaired with roof cement before the coating is applied.

Application Guidance

Apply BULLDOG Fiber Roof Coating #106AF by brush, roller, or spray. The roof surface should be dry and dirt-free before application. Any cracks, seams, or damaged areas should be filled with roof cement prior to coating. Air intakes should be covered before applying the coating and remain covered while the product is curing.

As with all roof coating applications, proper surface preparation is essential. A coating can only perform as well as the surface beneath it allows. For roofs with active leaks, trapped moisture, severe deterioration, or unknown roof conditions, a roof analysis should be completed before applying any coating system.

Coverage Rate

For bituminous composition roofs, apply BULLDOG Fiber Roof Coating #106AF at a rate of 3 to 4 gallons per 100 square feet. For metal roofs, apply at a rate of 2 gallons per 100 square feet. When applied at a rate of 100 square feet per gallon, the dry film thickness without absorption is approximately 10 mils.

Dry Time and Service Temperature

Dry time at the recommended rate of application is approximately 3 to 5 days, depending on weather, surface conditions, coating thickness, and ventilation. BULLDOG Fiber Roof Coating #106AF is designed for a service temperature range of -30°F to +150°F.

Performance Notes

BULLDOG Fiber Roof Coating #106AF is formulated to remain elastic and adhere well to appropriate roofing surfaces. Testing under ASTM D 4479 shows no sagging or blistering at 60°C and no cracking or separation at 0°C. These performance characteristics help make it a dependable option for maintenance coating applications where flexibility and surface protection matter.
