❌ This product is NOT suitable if you need to:

• Use on surfaces with active oil or grease contamination (clean and degrease first)

• Apply to wet, damp, or saturated surfaces (surface must be dry before application)

• Apply to bare metal roofs without priming (prime with Teamac Zinc Phosphate Primer first for optimal adhesion and rust prevention)

• Use on unstable or damaged roofs (repair roof structure before coating)

• Achieve instant full hardness (full hardness requires 5–7 days—plan for curing time)

• Apply in temperatures below 7°C (minimum application temperature 7°C for proper cure)

• Use on interior surfaces (designed for exterior roofs only)

Coo-Var Solar Reflecting Aluminium Paint is a bituminous-based heat reducing roof coating designed to reflect sunlight and stop buildings absorbing heat, lowering internal temperatures for more bearable working and living conditions whilst reducing energy bills by avoiding costly cooling. Unlike standard roof coatings that absorb heat, this aluminium pigment formulation reflects solar radiation to keep buildings cooler in summer.

Developed by Coo-Var with over 115 years of British coating expertise, Solar Reflecting Aluminium Paint is the professional solution for felt roofs, metal roofs, concrete roofs, factory roofs, warehouse roofs, and commercial buildings requiring heat reduction and energy savings. The bituminous-based aluminium formulation reflects sunlight whilst providing weatherproof protection for felt, metal, concrete, wood, and brick roofs.

When factory roofs, warehouse roofs, and commercial buildings are exposed to intense summer sunlight, heat absorption creates unbearable internal temperatures, reduces productivity, and increases cooling costs. Coo-Var Solar Reflecting Aluminium Paint's reflective coating deflects solar radiation to reduce heat buildup whilst the weatherproof formulation protects roofs from UV damage and weathering.

The bituminous-based formulation provides superior adhesion and durability on roofs. Apply as supplied - no thinning required. The quick-drying properties (touch dry 3 hours, hard dry 12 hours) allow fast project completion. Coverage of 4–6 m² per litre makes it cost-effective for large roof areas. The aluminium finish provides long-lasting heat reflection and roof protection.

Suitable for exterior roofs including felt, metal, concrete, wood, and brick in commercial, industrial, and residential environments. Apply 2 coats for optimal heat reflection and weatherproof protection. The reflective coating reduces internal temperatures, improves working conditions, and lowers energy bills by reducing cooling requirements.

Manufactured in the UK to rigorous standards and trusted by factory managers, facilities managers, property owners, and building managers for heat reduction and energy savings.

What is Coo-Var Solar Reflecting Aluminium Paint and when should I use it?

Coo-Var Solar Reflecting Aluminium Paint is a bituminous-based heat reducing roof coating that reflects sunlight to stop buildings absorbing heat. Use it when you need to lower internal temperatures, improve working conditions, and reduce energy bills in factories, warehouses, workshops, and commercial buildings.

How does Solar Reflecting Aluminium Paint reduce heat?

The aluminium pigment formulation reflects solar radiation instead of absorbing it. This deflects sunlight away from the roof, stopping heat buildup inside the building. This lowers internal temperatures, creates more bearable conditions, and reduces cooling requirements.

How much will this reduce my energy bills?

Energy savings depend on building size, insulation, and cooling usage. By reflecting sunlight and lowering internal temperatures, Solar Reflecting Aluminium Paint reduces cooling requirements and air conditioning costs. Many users report significant reductions in summer energy bills.

Can I use Solar Reflecting Aluminium Paint on any roof type?

Solar Reflecting Aluminium Paint is suitable for felt roofs, metal roofs, concrete roofs, wood roofs, and brick surfaces. Ensure roof is stable and in good condition before application. Repair any damage before coating. Prime bare metal roofs with Teamac Zinc Phosphate Primer first.

How many coats of Solar Reflecting Aluminium Paint do I need?

For optimal heat reflection and weatherproof protection, apply 2 coats. Allow minimum 12 hours or overnight between coats. The two-coat system provides maximum solar reflection and roof protection.

How long does Solar Reflecting Aluminium Paint take to dry?

Touch dry in 3 hours, hard dry in 12 hours at 20°C. Allow minimum 12 hours or overnight before recoating. Full hardness for maximum durability in 5–7 days. Drying times may be extended in cooler temperatures or high humidity.

Do I need to thin Solar Reflecting Aluminium Paint?

No, apply as supplied - do not thin. The paint is ready to use straight from the tin.

How much coverage can I expect from Solar Reflecting Aluminium Paint?

Solar Reflecting Aluminium Paint provides approximately 4–6 m² per litre per coat at 45 µm DFT. A 5L tin covers 20–30 m² per coat. Coverage may vary depending on surface porosity. We recommend ordering 10–15% extra for surface variation.

Is Solar Reflecting Aluminium Paint water-based or solvent-based?

Solar Reflecting Aluminium Paint is bituminous-based (solvent-based). Clean tools with SPO Thinners, not water. Ensure good ventilation during application and drying.

Do I need to prime metal roofs before applying Solar Reflecting Aluminium Paint?

Yes, prime bare metal roofs with Teamac Zinc Phosphate Primer for optimal adhesion and rust prevention. This ensures long-term durability and prevents rust bleeding through the coating. For previously painted metal, ensure coating is sound and well-adhered.

Can I use Solar Reflecting Aluminium Paint on interior surfaces?

No, Solar Reflecting Aluminium Paint is designed for exterior roofs only. It is formulated to reflect sunlight and provide weatherproof protection on exterior surfaces.

Will Solar Reflecting Aluminium Paint protect my roof?

Yes, Solar Reflecting Aluminium Paint provides weatherproof protection whilst reflecting heat. It protects roofs from UV damage and weathering, extending roof lifespan. Dual benefit of heat reduction and roof protection.

What products do I need to apply Solar Reflecting Aluminium Paint?

We recommend using Teamac Zinc Phosphate Primer for priming bare metal roofs, SPO Thinners for cleaning tools, and Application Tools (brushes, rollers, and trays) suitable for solvent-based paints. This complete system ensures maximum adhesion and heat reflection.

Complete Your Solar Reflecting System:

Teamac Zinc Phosphate Primer – Prime bare metal roofs before applying Solar Reflecting Aluminium Paint for optimal adhesion and rust prevention

SPO Thinners – Clean tools after application

• Application Tools – High-quality brushes, rollers, and trays for smooth, efficient application
