Introducing Metal Primer: The Ultimate Waterbased Solution for Metal Roof Surfaces.
Metal Primer is a specialised primer designed to cater to the unique needs of metal roof surfaces. This high-performance product is the ultimate solution for preparing metal surfaces for subsequent coatings, ensuring optimal adhesion and durability.
Metal roofs require a primer specifically formulated to address the challenges associated with metal surfaces. With its advanced formulation, Metal Primer can promote superior adhesion on various types of metal roofs. Applying this primer creates a strong and stable foundation for using NuTech Paint’s range of topcoat systems, ensuring long-lasting and visually appealing results.
Metal Primer is a water-based acrylic primer and can be applied to a range of metal surfaces such as:
- New and old galvanised metal
- Pre-coated zinc steel sheeting
- Coated metal sheet roofing
- Facade cladding
- Fencing
Surfaces coated with Metal Primer must be overcoated with a Nutech exterior durable water-based coating.
Benefits
- 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

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 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.
Warnings
This primer is not recommended for use over high gloss coatings
