Eagle DoubleCoat Liquid Waterproofing Aluminium, a liquid elastomeric waterproofing membrane reinforced with microfibers and high aluminium content, for waterproofing of most types of roof surfaces and exposed metal structures. Highly recommended for industrial units and warehouses.

Eagle DoubleCoat Liquid Waterproofing provides waterproofing and solar reflection on most types of roof surfaces including galvanised steel, iron zinc, asbestos, cement, roofing felt, asphalt and bituminous roof coatings. Being elastomeric and self-reinforced with microfibers and a high aluminium content, Eagle DoubleCoat needs just one coat and can be installed quickly on its own or in combination with a carrier membrane which achieve up to 15 years guarantee, due to its tough polyester reinforcement and UV protection.

Features and Benefits

  • Resistant to chemical attacks. DoubleCoat Pro-Reflect has been used in high aggressive environments such as chemical and dairy factories proving a high resistance to acid rain and chemical attacks.
  • Energy Saving. DoubleCoat Pro-Reflect has a high reflection capacity to provide owners and building developers energy savings.
  • Self-reinforced. Double Coat Pro-Reflect contains micro-fibres that act as a carrier and reduces the application time due to the necessity to apply many coats with a reinforcement embedded.
  • Permanently Elastomeric. Cold Applied and one-layer application. Bridges small holes, cracks and splits.
  • Any damage caused to the roof can be easily repaired with DoubleCoat Pro-Reflect.
  • Wide Range of guarantees available from 10+ years. Exceeds ASTM D2824


All surfaces must be clean, dry and free from dust and loose debris. Freshly applied coatings should be allowed to weather for 2 weeks prior to the application of Double Coat. All traces of fungi and algae growth should be removed using a stiff bristled brush or low-pressure water jet. Where algae and fungi have been removed, the surface should be treated with a fungicidal wash.

Stir the container thoroughly before use to ensure that no deposits are left at the bottom of the container. Double Coat may be applied by brush or sprayed. Do not apply in wet weather or when rain is threatened, or when poor drying conditions exists. As a protective measure on most well prepared surfaces which are in sound conditions, one layer of Double Coat is normally adequate.Application Rates Smooth, even surfaces 2m2 per litre. Uneven, rough surfaces 1m2 per litre. Dry Film Build Approx. 0.3mm thickness at 2m2 per litre

Asbestos, cement and porous surfaces should be first primed with Eagle fast drying primer.


The rate of application is between 1 -2 square meters per litre per coat, depending on the conditions of the surface. Do not coat windows, roof lights, glass or translucent sheets as they will constitute a hidden hazard.

Drying Time   

Drying time is around 1-2 hours, in most of weather conditions.

We ALWAYS recommend a trial area is coated to ensure the product meets your requirements before use.
