EnduRE30C Gen 5 — Concrete Roofs & Walls
CSIRO-Tested Radiative Cooling Performance (SRI 120.8)
EnduRE30C Gen 5 is a rare-earth enhanced Passive Daytime Radiative Cooling (PDRC) coating engineered specifically for concrete roofs, concrete tiles, terracotta tiles, rendered walls, and masonry surfaces. It reduces surface temperatures by up to 30°C and cuts building cooling energy loads by 25–40% — with zero power input and no mechanical system required.
Unlike conventional cool roof paints that rely solely on whiteness to reflect heat, EnduRE30C Gen 5 works through two complementary mechanisms:
1. High Solar Reflectance — Reflects 93.2% of total solar energy, blocking UV and infrared radiation before it heats the surface.
2. Infrared Atmospheric Window Emission — Rare earth compounds actively re-radiate absorbed heat through the 8–13 µm atmospheric window directly to the cold sky, even during peak daytime hours.
This dual-action PDRC technology means the coating continues to dissipate heat even when solar reflectance alone is insufficient — making it significantly more effective than standard reflective roof paints in Australia's harsh climate.

Why Gen 5 for Concrete?
Most reflective roof coatings rely entirely on whiteness for thermal performance — meaning colour options are severely limited and performance degrades as the surface weathers and dirties. EnduRE30C Gen 5 is engineered for radiative cooling through its rare earth formulation, not just whiteness. This means it performs in custom colours, maintains effectiveness over time, and delivers active heat dissipation that goes beyond simple solar reflection.
The silicone-acrylic binder system provides deep penetrating adhesion to porous concrete and masonry substrates — resisting efflorescence, moisture ingress, and surface chalking common in Australian conditions.
Sustainability
By lowering surface temperatures and reducing air conditioning demand, EnduRE30C Gen 5 supports reduced electricity consumption and associated carbon emissions. Water-based and non-toxic, it is designed to support green building outcomes and NCC energy efficiency compliance.
Built for Australia's heat — EnduRE30C Gen 5 delivers smarter cooling, improved comfort, and long-lasting exterior protection.

EnduRE30C Gen 5 for Concrete
Practical guidance for applying EnduRE30C R-E Coating Gen 5 for Concrete, a silicone-acrylic radiative insulation coating designed for concrete roofs, concrete tiles, rendered walls and masonry substrates. For project-specific requirements and detailed step-by-step instructions, please refer to the official Construction Manual.
1) Application Methods
- Airless spray (recommended for best consistency and productivity)
- Air spray
- Roller or brush (for small areas, edges, touch-ups and repairs)
2) Drying & Recoat Time
Drying and recoat times depend on weather, airflow and substrate condition. As a general guide, under standard conditions:
- Surface dry: approximately ≤ 1 hour
- Hard dry: approximately ≤ 24 hours
- Minimum recoat time: 2 hours
- Maximum recoat window: up to 72 hours
Reference conditions: ambient temperature 5–35°C, relative humidity ≤ 75% RH.
3) Application Conditions
- Substrate must be sound, clean and dry, free from dust, grease, salt, mould and loose material.
- Substrate moisture content: ≤ 10%
- Substrate pH: neutral range (pH 7–9)
- Application temperature: 5–35°C
- Relative humidity: ≤ 75% RH
- Ensure adequate ventilation in enclosed or confined spaces during application and drying.
4) Dilution Guidance
Dilution may be required depending on application method and site conditions. Where dilution is used, it should be done with deionised water.
Important: For exact dilution ratios and layer-specific guidance, always follow the Construction Manual and project specifications.
5) Professional Use Notice
- EnduRE30C Gen 5 for Concrete is designed for professional application.
- Actual coverage, drying time and cooling performance may vary depending on substrate condition, surface preparation, weather, coating thickness and application technique.

Radiative Cooling Principle for Coatings
Stay Cooler, Naturally with Rare Earth Technology
Easyto’s EnduRE30C™ Rare Earth Coatings use advanced radiative cooling to keep building surfaces dramatically cooler under the sun. Unlike traditional paints that only reflect visible light, our coatings combine thermal barrier, solar reflection, and natural radiative emission for all-round heat control. This results in lower indoor temperatures, reduced HVAC loads, and improved energy efficiency.
How Radiative Cooling Works
The coating structure consists of multiple functional layers: a protective surface, a rare earth radiative cooling layer, and a heat-insulating substrate. Together, these layers reflect, block, and re-radiate solar energy — ensuring surfaces stay cooler without compromising durability or aesthetics.
Three Key Mechanisms
1. Thermal Barrier
Heat conduction is reduced by using rare earth materials with low thermal conductivity, preventing excess heat from transferring indoors.
2. Thermal Reflection
The coating reflects solar radiation energy across a wide wavelength range (200–2500nm), reducing the amount of heat absorbed by the building surface.
3. Thermal Radiation
Any absorbed solar energy is re-emitted as harmless far-infrared radiation (8–13μm) back into the sky through the atmospheric window — a natural, maintenance-free cooling process.
Why Rare Earth Makes the Difference
Unlike conventional titanium-based paints, Easyto’s rare earth coatings maintain high stability, strong solar rejection, and long-term weather resistance. This ensures performance does not fade with time and continues to deliver measurable energy savings year after year.
Real-World Benefits

Applications
Radiative cooling coatings are ideal for metal roofs, warehouses, demountable, telecom cabinets, tanks, animal barns, and more. By staying cooler naturally, these coatings extend material lifespan, improve occupant comfort, and lower operating costs.
