Coo-Var Solar Reflecting White Paint - Water-Based Heat Reducing Roof Coating for Pitched Roofs

• Reduce heat buildup on pitched roofs (concrete, stable felt, wood, brick) with water-based solar reflecting paint

• Cut energy bills and cooling costs by deflecting sunlight before it heats the building

• Extend pitched roof lifespan by protecting against thermal stress, cracking, and UV degradation

• Apply fast-drying water-based coating (touch dry 45 minutes, hard dry 3 hours) for quick application

• Use easy-application water-based paint with brush or roller and water cleanup (DIY-friendly and professional-grade)

• Create cooler, safer, and more comfortable working conditions in warehouses, factories, and workshops

• Protect pitched roofs on conservatories, agricultural buildings, commercial buildings, and industrial roofs

• Use cost-effective heat reduction solution from Coo-Var (115+ years British coating expertise)

• Use on flat roofs or areas with standing water (this paint is for pitched roofs only—consult our experts for flat roof coatings)

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

• Use on unstable or deteriorating felt (felt must be stable and well-adhered—repair or replace damaged felt first)

• 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 drying)

• Use as a waterproofing solution (this paint provides heat reduction, not waterproofing—use appropriate roof waterproofing products)

• Apply in freezing conditions or high humidity (apply in temperatures above 7°C for optimal drying)

Coo-Var Solar Reflecting White Paint is a water-based heat reducing roof coating designed to deflect sunlight and control heat buildup on pitched roofs. Unlike standard roof paints that absorb heat, this solar reflective formulation reflects harsh sunlight, keeping buildings cooler, reducing energy bills, and extending roof lifespan by protecting against thermal stress and cracking.

Developed by Coo-Var with over 115 years of British coating expertise, Solar Reflecting White Paint is the cost-effective solution for reducing heat in warehouses, factories, workshops, conservatories, and commercial buildings. The water-based formulation provides easy application and cleanup whilst delivering professional solar reflective performance on pitched roofs.

When buildings with pitched roofs are exposed to intense sunlight, heat buildup creates uncomfortable working conditions, increases cooling costs, and accelerates roof deterioration through thermal stress and cracking. Coo-Var Solar Reflecting White Paint's solar reflective formulation deflects sunlight before it can heat the roof surface, reducing internal temperatures, cutting energy bills, and protecting the roof structure.

The water-based formulation is easy to apply by brush or roller, with fast-drying properties (touch dry 45 minutes, hard dry 3 hours) allowing quick application and minimal disruption. The white solar reflective finish provides maximum sunlight reflection whilst protecting pitched roofs from UV degradation and weathering.

Suitable for pitched roofs including concrete, stable felt, wood, and brick surfaces. Not suitable for flat roofs or areas with standing water. Apply 1–2 coats depending on surface condition and heat reduction required. The solar reflective coating reduces cooling costs, boosts productivity in hot weather, and extends roof lifespan by protecting against thermal stress.

Manufactured in the UK to rigorous standards and trusted by warehouse managers, factory owners, facilities managers, and property owners for cost-effective heat reduction and roof protection on pitched roofs.

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

Coo-Var Solar Reflecting White Paint is a water-based heat reducing roof coating designed to deflect sunlight and control heat buildup on pitched roofs. Use it when you need to reduce internal temperatures, cut energy bills, and extend roof lifespan on warehouses, factories, workshops, conservatories, and commercial buildings with pitched roofs.

How does solar reflecting paint reduce heat?

Solar reflecting paint deflects harsh sunlight before it can heat the roof surface. The white solar reflective finish reflects sunlight away from the building, reducing heat absorption and keeping internal temperatures cooler. This reduces cooling costs and creates more comfortable working conditions.

Can I use Solar Reflecting Paint on flat roofs?

No, Solar Reflecting Paint is designed specifically for pitched roofs only. It is not suitable for flat roofs or areas with standing water. For flat roof applications, consult our experts for appropriate flat roof coatings.

What surfaces can I apply Solar Reflecting Paint to?

Solar Reflecting Paint is suitable for pitched roofs including concrete, stable felt, wood, and brick surfaces. Ensure felt is stable and well-adhered before application. Not suitable for unstable or deteriorating felt, flat roofs, or areas with standing water.

How many coats of Solar Reflecting Paint do I need?

For maximum heat reduction, apply 2 coats. The first coat seals the surface, the second coat provides maximum solar reflection. Allow minimum 6 hours between coats. Single coat application may be sufficient for moderate heat reduction.

How long does Solar Reflecting Paint take to dry?

Touch dry in 45 minutes, hard dry in 3 hours at 20°C. Allow minimum 6 hours before recoating. Full hardness in 5–7 days. Drying times may be extended in cooler temperatures or high humidity.

Can I thin Solar Reflecting Paint?

Yes, Solar Reflecting Paint can be thinned with up to 5% clean water if required for easier application. However, for maximum solar reflection and coverage, apply as supplied without thinning.

How much will Solar Reflecting Paint reduce my energy bills?

Energy bill reduction depends on building size, insulation, and climate. Most users report noticeable temperature drops and reduced cooling costs. The solar reflective coating deflects sunlight before it heats the building, reducing the need for air conditioning and cooling systems.

How long does Solar Reflecting Paint last?

Solar Reflecting Paint provides long-lasting heat reduction and roof protection. Lifespan depends on roof exposure, weather conditions, and maintenance. Regular inspection and reapplication every 3–5 years maintains maximum solar reflection and roof protection.

Can I apply Solar Reflecting Paint to metal roofs?

Solar Reflecting Paint is suitable for pitched roofs including concrete, stable felt, wood, and brick. For metal roofs, consult our experts for appropriate metal roof coatings with solar reflective properties.

How much coverage can I expect from Solar Reflecting Paint?

Solar Reflecting Paint provides approximately 8 m² per litre per coat at 45 µm DFT. A 5L tin covers 40 m² per coat. Coverage may vary depending on surface porosity and texture. We recommend ordering 10–15% extra for surface variation and touch-ups.

Is Solar Reflecting Paint waterproof?

Solar Reflecting Paint provides heat reduction and UV protection, not waterproofing. For waterproofing pitched roofs, use appropriate roof waterproofing products. Solar Reflecting Paint can be applied over properly waterproofed roofs for heat reduction.

What products do I need to complete my pitched roof project?

We recommend using professional Brushes, Rollers and Trays for application. Ensure the pitched roof surface is clean, dry, and stable before application. For damaged felt or roof repairs, use appropriate roof repair compounds before applying Solar Reflecting Paint.
