Karnak 28 Perfectseal Non-Fibered Aluminum Roof Coating, 5 Gallon Pail, Silver
Karnak 28 Perfectseal is a non-fibered aluminum roof coating made from selected asphalts and pure aluminum pigment flakes blended with petroleum solvents and mineral fillers. The line is available in 5 gallon pails and 55 gallon drums; this item is the 5 gallon pail in silver. It is applied over weathered asphaltic roof surfaces such as BUR and modified bitumen.
Key Features:
- Reflective aluminum shield: Aluminum flakes leaf to the surface as the coating dries, forming a reflective metallic shield over the roof substrate.
- Sun protection: Reflects over 50% of the sun's rays, protecting asphaltic oils in the roof from being cooked out by intense UV exposure.
- Cooler interiors: Helps reduce indoor building temperatures and improve inside living and working conditions during hot summer months.
- Non-fibered formula: Made of selected asphalts and pure aluminum pigment flakes with petroleum solvents and mineral fillers, no fibers added.
- Asphaltic substrate use: Intended for application over asphalt-based roof surfaces including BUR and modified bitumen membranes.
- Container options: Available in 5 gallon pails and 55 gallon drums to match job size.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Aluminum coatings are a cost-effective way to extend the life of aging asphalt roofs by blocking UV that drives oil loss. Confirm the substrate has weathered the required 180 days for new BUR before coating, and apply in suitable dry conditions so the aluminum flakes leaf evenly. For large commercial jobs, the 55 gallon drum reduces packaging waste versus pails.
Contains petroleum solvents: apply outdoors in well-ventilated conditions, keep away from ignition sources, and follow all label safety instructions.
