Anti-Corrosion Water-Based primer for metal surfaces
Metal Primer is a water-based acrylic primer which exhibits exceptional adhesion and protection to a range of metal surfaces such as:
- New and old galvanised metal
- Pre-coated zinc steel sheeting
- Coated metal sheet roofing
- Facade cladding
Surfaces coated with Metal Primer must be overcoated with a Nutech exterior durable water-based coating.
- 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
- Excellent adhesion to a wide range of metal substrates
- Outstanding durability

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 a 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 50°C.
This primer is not recommended for use over high gloss coatings
