Technical Data Sheet

Safety Data Sheet

1. What is Coo-Var Solar Reflecting Paint Aluminium used for?

Coo-Var Solar Reflecting Paint aluminium is a bitumen, aggregated coating designed to deflect sunlight and reduce heat build-up in roofs and internal areas. It’s commonly used on substrates like concrete, felt, brick, and wood to create a cooler interior environment.

2. How does it reduce heat build-up?

The aluminium flakes in the paint act like tiny mirrors. When sunlight (especially infrared radiation, which carries heat) hits the coated surface, much of it is reflected away rather than absorbed. This prevents the surface from heating up as much.

3. What surfaces can it be applied to?

It’s suitable for a range of stable surfaces, including: bitumen felt roofs, asphalt, concrete, metal, weathered roofing substrates.

4. How do I apply the paint?

Surface Prep: Ensure all surfaces are clean, dry, and free from contaminants. Remove flaking material and sand previously painted surfaces to provide a good key.

5. How long does it take to dry?

Typically, the paint is touch-dry within 4 hours and recoatable in 12 hours, depending on temperature and humidity. This quick drying time means you can re-coat or make adjustments sooner, minimising project downtime.

7. How long does the heat-reducing effect last?

When applied correctly, the paint provides a long-lasting, cooling barrier throughout the hot season. Reapply as needed if you notice diminished effectiveness over time or after heavy weather exposure.
