Promac Rubber Duck Bituminous Aluminium is an oil-modified protective coating formulated to improve the durability of bitumen-based waterproofing systems. Its aluminium pigmented finish reflects sunlight and helps reduce surface temperature, while also protecting underlying waterproofing layers from UV degradation. This makes it a practical solution for extending the service life of torch-on membranes and bituminous surfaces exposed to outdoor conditions. Available in a 5L tin, it is suitable for maintenance and protective coating work on roofs and related waterproofing surfaces.

Key Features

• Highly reflective aluminium finish helps reduce surface temperature
• Protects bitumen waterproofing systems and torch-on membranes
• UV resistant for improved outdoor durability
• Provides water resistance for added protection
• Easy to apply using brush, roller, or spray equipment
• Suitable for use on bituminous, steel, and galvanised steel surfaces

Spreading Rate

• Bituminous surfaces: approximately 6 – 8 m² per litre per coat
• Steel and galvanised steel: approximately 12 – 14 m² per litre per coat
• Coverage depends on surface porosity, profile, and application method

Application Guidelines

• Apply two or more coats to the prepared surface
• Suitable for application with a brush, roller, or spray equipment

Applications

• Coating bitumen waterproofing systems
• Protecting torch-on membranes
• Roof maintenance and UV protection
• Protective coating on steel and galvanised steel surfaces
