AluShield®
Reflective Bitumen Aluminium Paint SB
ALUSHIELD® Reflective Bitumen Aluminium Paint SB is a one-component, solvent-based, polymer-modified bitumen aluminium coating designed to provide a highly reflective protective and decorative finish over bituminous surfaces and waterproofing systems.
The brilliant aluminium finish helps protect underlying bitumen against UV degradation, water, moisture and weathering, while advanced polymer modification improves curing, application and long-term flexibility compared with traditional bitumen alkyd aluminium coatings. Its flexible film and good elongation properties also assist in bridging hairline cracks, making it particularly suited to roof and waterproofing maintenance applications.
Pack Sizes: 5, 20 & 200 Litre

Intended Uses
ALUSHIELD® Reflective Bitumen Aluminium Paint SB is designed as a decorative and protective reflective finish for tar, bitumen and bituminous waterproofing surfaces. Its primary function is to shield these substrates from ultraviolet degradation while providing additional protection against water, moisture and exterior weathering.
The polymer-modified formulation offers improved flexibility and curing compared with conventional bitumen alkyd aluminium paints. This makes it particularly suitable for exposed waterproofing systems where the underlying bituminous material needs protection from sunlight and environmental exposure.
Its good elongation and long-term flexibility also help the coating accommodate minor substrate movement and bridge hairline cracks, contributing to longer maintenance intervals and improved resistance to cracking.
Typical Applications:
- Bitumen-coated roofs
- Torch-on bituminous waterproofing
- Bituminous waterproofing membranes
- Sheet waterproofing membranes
- Tar-based surfaces
- Bitumen-coated surfaces
- Reflective roof maintenance coatings
- Waterproofing refurbishment
- Roof waterproofing maintenance
- Bitumen-coated cast iron pipes
- Fence posts
- Galvanized steel
- Appropriately primed mild steel
- Exterior metal components
- Commercial roofs
- Industrial roofs
- Factory and warehouse roofs
- Building maintenance
- Waterproofing maintenance systems
The product is particularly useful as a reflective finishing layer over exposed bituminous waterproofing, where it helps protect the underlying material against UV degradation while providing a bright aluminium appearance.
