Metal Primer

Anti-Corrosion Water-Based primer for metal surfaces

Nutech Anti-Corrosion Water-Based Co-Polymer Acrylic Metal Primer is designed as a primer for new and weathered galvanised and metal sheeting.

This primer is supplied standard in a mid-grey colour suitable for topcoating with NuFlex, TileFlex or any other durable Nutech external acrylic coating.

Application and Features

Nutech Metal Primer is an acrylic coating, which demonstrates exceptional adhesion to a range of substrates including:

  • All Metal Roofing surfaces
  • New/Older Galvanised Metal
  • Pre-coated zinc and steel sheeting
  • Can also be used as a primer over coated metal sheet roofing products

The coating provides good chemical resistance, weatherability. It is suitable for application by brush, roller or airless spray.

Surfaces primed with Nutech Metal Primer perform exceptionally under conditions of hot, cold and wet weather, provided they are correctly cleaned and topcoated with a suitable protective finish.


  • Improved hardness and flexibility
  • Excellent long term resistance to corrosion and rust
  • Easy application and clean up
  • Suitable for new and weathered galvanised and zinc metal sheeting
  • Weatherproof
  • Excellent adhesion to a wide range of metal and masonry substrates
  • Outstanding durability
  • Oil and water resistant

Application Guide

The surface should be cleaned to remove all contaminants and dirt and any loose coating. A suitable surface is usually achieved using a high-pressure water cleaner (greater than 2500 p.s.i.). If new galvanised sheets are heavily contaminated with oil and machine lubricants, the surface must be washed with a suitable degreaser or solvent before coating.

Nutech Metal Primer used for metal roof sheeting must be over coated with NuFlex, TileFlex, NXT Cool Zone or other Nutech water based coating suitable for external exposure.

Application on non porous substrate including metal sheeting, requires adequate curing of this product before top coating with Nu-Flex, Tileflex or NXT Cool Zone.

Same day top coating in winter or cold weather is not recommended. Same day top coating in cold weather will retard curing of this primer and surface blisters and delamination bubbles may result, unless adequate curing of the primer is ensured.

Primer adhesion may be affected when applying on hot metal sheeting. Ensure substrate surface temperatures do not exceed 30°C.


This primer is NOT RECOMMENDED for coating over high gloss coatings on metal sheet roofing.
