Waterproof elastomeric membrane for roofs
Double Coat Pro-Reflect
Liquid roofing membrane — cost-effective waterproofing for industrial roofs.
DUAL FUNCTION is a liquid roofing membrane, a liquid elastomeric waterproofing membrane reinforced with microfibers and featuring a high aluminum content.
Ideal for waterproofing most substrates commonly found on roofs, including galvanized steel, zinc sheets, asbestos, cement, asphalt felt, asphalt, and bituminous sheets. Suitable as an anticorrosive for exposed metal structures such as storage tanks, pipes, and cladding, it is highly recommended for industrial facilities and warehouses.
USES:
- Waterproofing with UV-reflective properties for roofs made of various materials. Coolroofing system.
- Corrosion protection for metal structures exposed to harsh weather conditions.

TDS Double Coat Pro-ReflectApplications
The substrate must be clean, dry, and free of dust and loose debris. Freshly applied coatings should be left exposed to the elements for 2 weeks before applying DUAL FUNCTION. All traces of fungal and algae growth must be removed with a stiff-bristle brush or a low-pressure water jet. Once algae and fungi have been removed, the surface must be treated with a fungicide.
Storage
Shelf life of 12 months in hermetically sealed containers, stored in cool, dry conditions. Make sure to mix well if the product has not been used for several months.
Make sure the material is not contaminated with water, especially in partially used cans.

All Advantages
In new construction, the DUAL FUNCTION waterproof roofing membrane can be applied on its own or in conjunction with a bitumen sheet, providing warranties of up to 25 years thanks to its strong polyester reinforcement and UV protection. The system can be installed in just one day, providing a quick solution for the contractor and a long-lasting waterproofing system for the building owner.
- Any damage to the roof can be easily repaired with DUAL FUNCTION, a liquid roofing membrane.
- Energy savings. DUAL FUNCTION boasts a high reflective capacity that delivers energy savings of around 30% during the hottest periods, resulting in efficient roofing.
- Resistant to chemical agents. DUAL FUNCTION has been used in highly aggressive environments, offering high resistance to chemical attacks and acid rain, among other hazards.
- Corrosion-resistant and waterproof protection for metal pipes and tanks.
- An extensive range of warranties is available, spanning from 10 to 25 years. Exceeds ASTM D2824.
- Direct application from the can, with no need to add additives or make other mixtures, avoiding the risk of errors on site.
- Self-reinforcing. DUAL FUNCTION contains microfibers that act as carriers, reducing application time. Permanently elastomeric. Cold application in a single coat. It bridges small holes, cracks, and crevices.
Mix the container well before use to ensure there are no deposits left at the bottom. DUAL FUNCTION can be applied by brush or spray. Do not apply in humid weather, when rain is forecast, or under poor drying conditions. As a protective measure, one coat of DUAL FUNCTION is typically sufficient for most surfaces that have been properly prepared and are in good condition. Asbestos, cement, and porous surfaces must first be primed with a fast-drying bituminous primer. Coverage is 1 to 2 m² per liter per coat, depending on surface conditions. Do not cover windows, skylights, glass, or translucent sheets, as they would pose a hidden hazard. The drying time is approximately 1 to 2 hours under most weather conditions.
