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.

All surfaces to be treated must be clean, dry and free of loose debris that may interfere with proper bond. Surfaces that have previously been coated should be examined carefully and tested for adhesion to the substrate. This can be accomplished by applying a strip of scotch tape to the coated surface. The tape should be thoroughly pushed into full contact and then pulled away at a 90° angle. Observe the adhesive surface for any dislodged coating particles. If the tape has pulled away a significant quantity of coating, or if it has loosened the coating from the substrate, the coating should be removed. Loose coating should be thoroughly removed by abrasion, pressure washing or other available technique. Some coatings that are firmly bonded but have reticulated (mud cracked) and the edges lifted will need abrading to present a uniform, smooth surface for coating. Some very inert surfaces, such as epoxy, will require abrading and/or a special primer coat. ROOFDX COPPER is applied straight out of the can after 2 minutes of low speed mechanical stirring. Apply the product using brush, roller. or airless spray technique. The product should be applied in 2 coats at an overall rate of 50 square feet per gallon, achieving a wet film thickness of 30 mils or 15 mils per coat.


Clean up:

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



Do not apply to frozen or saturated surfaces. Cold temperatures will slow down the drying time. Do not apply if precipitation is forecast within 4 hours after application.
