Cool roof paint - Green roof membrane
CoolTop
Cool roof paint system for Energy Efficiency.
CoolTop reflects our commitment to a more sustainable world. The coating created by Eagle Waterproofing – CoolTop reflects a high percentage of solar radiation, preventing its absorption and thus the accumulation of structural heat: Energy Efficiency.
CoolTop is a white, reflective, two-component coating applied to building roofs. Dark-colored roofs absorb a lot of heat, causing the building’s structural temperature to rise. The white color of our CoolTop cool roof paint reflects the sun’s rays, allowing the roof to accumulate less heat and thereby creating a thermal barrier, resulting in efficient roofing.
Advantages of CoolTop’s white color as a thermal insulation paint
- Reduced thermal load on the roof.
- Energy savings.
- Heat reflective.
- Protection of the building structure.
- Increased seal service life.
- Improved performance of roof-mounted equipment.
- Enhanced efficiency of solar panels.
- Universal solution: this insulating paint can be applied to most substrates, including bituminous membranes, EPDM membranes, fiber cement boards, PVC membranes, sheet metal, plastics, tiles, and slate. It can also be applied to ventilation, heating, and cooling ducts.
- Reduction of the “heat island” effect: applying CoolTop to adjacent buildings creates an area with different thermal characteristics from the rest of the urban core.
Process
- Surface preparation: cleaning, remediation, and possible repair.
- Application of CoolTop, an insulating paint, with or without Ultraprime CT primer, depending on the substrate.
- Apply CoolTop using a roller or an airless spray gun.

Application
CoolTop must be applied to a dry, firm substrate. Avoid capillary or negative moisture. The substrate temperature must be 3°C above the dew point, with an ambient temperature above 8°C and relative humidity below 80%.
CoolTop can be applied in a single coat (200 g/m²) using a roller, brush, or airless device. Thoroughly mix components A and B using a low-speed mixer to prevent air entrapment, until the mixture is homogeneous.
How to Use
Reflective coating for the thermal protection of waterproofing membranes
Asphalt or bituminous sheets, synthetic EPDM, TPO, or FPO membranes: Before applying CoolTop, clean the membrane surface and remove any dust, foam, oil, grease, or other contaminants that could compromise the system’s adhesion. For older systems, adjust and repair the sealing sheets as needed. Apply one coat of UltraPrime CT (approx. 180 g/m²) over the existing sheet as an adhesion promoter. Then, apply a single coat of CoolTop (200 g/m²) using a roller or airless device to create a flexible, continuous protective film with a glossy, durable, and highly reflective finish.
PVC membranes or metal substrates: Thoroughly clean the surface and remove any dust, foam, oil, grease, or other contaminants that could compromise the system’s adhesion. Secure the edges and seal the seams tightly. On metal, you can clean with a sandblast and/or use corrosion inhibitors if necessary. Apply CoolTop without primer using a roller or airless device in a thin layer (200 g/m²).
Technical Specifications
Coverage: A 5 kg package of CoolTop can cover approximately 25 m²; a 20 kg package, approximately 100 m² (coverage: 200 g/m² per coat).
Presentation: Metal containers. Two-component: base (component A) + hardener (component B). 5 kg (4.30+0.70 kg) and 20 kg (17.20+2.80 kg) containers. Reflective white color. Thermal paint.
Shelf life: 24 months for component A and 12 months for component B from the date of manufacture. Store in a dry place at a temperature between 5 and 35°C.
Handling and Transport
- Respiratory protection: Wear an approved air-purifying mask (for airless application).
- Skin protection: Wear rubber gloves. Remove immediately after contact. Wear clothing that covers the entire body. Wash with soap and water before eating or smoking.
- Eye/face protection: Wear safety glasses to prevent splashes and exposure to airborne particles (airless application).
- Waste: Avoid generating contaminated waste. It must be taken to an authorized waste treatment facility.
