Case study

Northcote super 6 roof — encapsulated with Noxyde

This Auckland home in Northcote still had its original super six asbestos-cement roof. Rather than the expense and risk of removal, the roof was cleaned, prepared and coated with Noxyde — creating a seamless, waterproof membrane that locks the asbestos fibres in place and adds decades of corrosion protection.

  • No removal of asbestos sheets required
  • Waterproof membrane locks fibres in place
  • Extends roof life by 20+ years
  • Same Noxyde system used on commercial and industrial roofs

Our flagship roof coating

Noxyde® — the longest-lasting roof coating in New Zealand

Noxyde is the only anti-corrosion waterproofing membrane on the market, and has been applied in many of New Zealand's most severe coastal corrosion environments for the last 29 years. It requires no additional corrosion primer when applied to prepared rusty surfaces — it carries its own anti-corrosion pigments and can be applied over clean rust.

  • Ultimate corrosion protection, even in severe conditions
  • 200% elastic coat — does not crack or peel
  • Excellent coverage of nuts, bolts and welds
  • Dry fall: saves preparation and clean-up time
  • Primer and topcoat in one

Noxyde anti-corrosion and waterproof protection — available in a range of sizes.

Where it can be applied

  • Corrugated iron and steel roofing
  • Roof plant, air-conditioning ducts and penetrations
  • Butynol and Nuralite
  • Torch-on membranes
  • Concrete roofs and decks
  • Super six asbestos-cement roofing
  • Bridges and structural steel in saltwater estuaries

Noxyde is not suited to areas of continuous water ponding. For roofs, gutters and decks that hold water, specify Eagle DoubleCoat continuous-ponding waterproofing instead — talk to us and we'll specify the right system.
