Crown Bituminous Aluminium Paint Technical Data Sheet (TDS) – Kenya
Crown Bituminous Aluminium Paint is a protective aluminium-bituminous coating formulated for waterproofing, heat reflection, and corrosion protection on metal roofing sheets, steel structures, pipelines, gutters, tanks, and industrial surfaces in Kenya.
The coating combines a durable bituminous barrier system with reflective aluminium pigments to help reduce moisture penetration, minimise roof heat absorption, and improve weather resistance in demanding outdoor environments.
Quick Product Summary
- Protective bituminous aluminium coating
- Designed for metal roofs, tanks, gutters, and pipelines
- Provides waterproofing and corrosion resistance
- Reflective aluminium finish helps reduce roof heat
- Coverage rate of approximately 8–10 m² per litre
- Suitable for brush, roller, and spray application
- Excellent resistance to outdoor weather exposure
Proper rust removal, surface preparation, and complete substrate drying are critical before application. For maximum durability, the coating should be applied as part of a full protective coating system.
What Is Crown Bituminous Aluminium Paint?
Crown Bituminous Aluminium Paint is a solvent-based protective coating that combines waterproofing bitumen technology with reflective aluminium pigments. It is specifically designed for industrial and roofing applications where moisture resistance, heat reflection, and corrosion protection are required.
The aluminium pigment creates a reflective metallic layer that helps reduce heat build-up on roofing surfaces, while the bituminous base forms a moisture-resistant protective barrier against weather exposure.

Frequently Asked Questions (FAQ)
What is bituminous aluminium paint used for?
Bituminous aluminium paint is used for waterproofing and corrosion protection on metal roofs, pipelines, gutters, tanks, and structural steel exposed to outdoor weather conditions.
Does bituminous aluminium paint reduce roof heat?
Yes. The reflective aluminium pigment helps reduce heat absorption on roofing surfaces by reflecting sunlight away from the substrate.
Can bituminous aluminium coating be applied on wet surfaces?
No. Surfaces must be completely dry before application because trapped moisture can reduce adhesion and cause premature coating failure.
Is primer required before applying bituminous aluminium paint?
Yes. Bare steel and rust-prone metal surfaces should be primed with a suitable anti-corrosion primer before coating application.
How does bituminous aluminium coating perform in coastal regions?
Performance in coastal and high-humidity regions depends heavily on correct surface preparation, priming, and coating system build-up due to increased salt exposure.
What is the coverage rate of Crown Bituminous Aluminium Paint?
The paint typically covers approximately 8–10 square metres per litre per coat depending on application method and surface condition.
