How to Apply Roofdx Copper
How to Apply Roofdx Copper


ROOFDX COPPER is an extremely tough, metallic, rubber-like, waterproofing coating that, being made with copper flakes, has a very attractive copper finish that will actually patina. This remarkable “liquid copper” coating can be used over all common roofing substrates and will give the appearance of copper sheet roofing at a fraction of the cost. Just like copper sheet, ROOFDX COPPER will develop a classic green patina, or may be sealed with Clearcoat 44 to maintain its new appearance.

Outstanding Features

  • Liquid copper coating made with real copper flakes.
  • Produces a fully adhered, seamless, high density, waterproofing membrane.
  • Protects substrate against rust, corrosion, UV damage, acid rain and fungal attack.
  • Easy to apply straight out of the container by brush, roller or airless spray.
  • May be used on vertical, slanted, and horizontal surfaces, and withstands ponding water.
  • Remains flexible, tough and weatherproof at low temperatures and will not flow at high temperatures.
  • Ten year material warranty.

Recommended for

Can be used over most metals, copper, rubber, concrete, modified bitumen, asphalt BUR, masonry, slate/tile, wood, and other approved surfaces.




Approximate 100 sq ft/gal, depending upon substrate. Two coats are recommended.

Preparation and Application

Surface Preparation
Surfaces must be dry, free of dirt, loose debris, oils, grease or any substance that could interfere with adhesion. Do not apply if the substrate or air temperature is predicted to drop below 35°F (2°C) within 4 hours after application. The application surface must remain at least 5°F (3°C) above dew point during the application and curing process.

Do not apply ROOFDX COPPER to wet, damp, or frozen surfaces. Do not apply if the area cannot be protected from precipitation for at least 4 hours after application. ROOFDX COPPER is applied directly out of the container after at least 2 minutes of low speed drill stirring. Do not thin the product. Apply in 2 coats using a soft brush, medium nap roller, or airless sprayer in a smooth, even technique. When applying with a roller or a brush, it is very important that the final brush strokes are in the same direction. This is to orient the Copper Flakes in the same direction.

Spray Application
For spray application use 30:1 airless pump, 3/8″ short hose and 33 to 37 tip

Recommended Thickness
20 mils Dry Film Thickness (DFT)

Drying Time
Approximately 24 to 36 hours per coat at 70°F (21°C) and 70% RH.

Clean up
Clean tools and equipment with xylene or toluene before ROOFDX COPPER begins to dry

Store in a dry area and protect from direct sunlight and freezing. Keep container tightly sealed. Shelf life is 2 years from date of manufacture when stored in a factory sealed container between 45ºF (7ºC) and 90ºF (32ºC).

Waste disposal must be in accordance with existing federal, state and local environmental control laws. Incineration is the preferred method of disposal.

Read the container label warning and Safety Data Sheet (SDS) for important health and safety information prior to the use of this product.
