Collection: Roof Coating Primers

The right primer is an important part of a successful roof coating system. ProTrade Warehouse supplies a range of roof coating primers and sealers from NuTech and Crommelin, with products formulated for different roof substrates and surface conditions.

Whether you are coating concrete roof tiles, terracotta, metal roofing or weathered asbestos cement, choosing a primer suited to the existing surface can help improve adhesion and prepare the substrate for the compatible roof coating.

Concrete Roof Tile Primers

Concrete roof tiles can become porous, powdery, chalky or weathered over time. Products such as NuTech NuPrime, SupaPrime and Master Sealer are designed for different concrete and masonry surface conditions, including porous and weathered substrates.

For particularly challenging surfaces, selecting the appropriate primer based on the condition of the existing roof is important. Always follow the manufacturer's preparation and application requirements before applying the roof coating.

Terracotta Roof Tile Primer

NuTech Elite Terracotta Primer is specifically designed for suitable terracotta roof tile applications. Using a primer formulated for the substrate can help create the appropriate base for the compatible topcoat system.

Metal Roof Primer

Metal roofing, gutters and cladding require a primer designed for metal substrates. NuTech Metal Primer is a water-based, corrosion-resistant acrylic primer designed for suitable steel, aluminium and galvanised metal surfaces.

It can be used as part of compatible NuTech roof coating systems, including Flexi-Shield, NXT Cool Zone, NuFlex and Tileflex. Refer to the relevant NuTech technical data sheet for compatibility and application requirements.

Asbestos Cement Primers & Sealers

For suitable weathered asbestos cement surfaces, our range includes Crommelin Fibroseal Primer and NuTech Asbestos Sealer. These products are designed to penetrate and seal suitable asbestos cement substrates as part of their respective coating systems.

Asbestos-containing materials require careful handling and appropriate safety procedures. Always follow current Australian requirements and the manufacturer's instructions, and use appropriately qualified professionals where required.

Choosing the Right Roof Primer

The correct primer depends on the roof material and condition of the existing surface. Before choosing a product, consider whether the substrate is concrete tile, terracotta, metal or asbestos cement, and whether the surface is porous, powdery, weathered or previously coated.

1. Identify the roof substrate: Determine the material and existing coating system.
2. Assess the surface: Check for porosity, powdering, weathering, corrosion or unstable existing coatings.
3. Choose a compatible primer: Select a primer designed for the specific substrate and surface condition.
4. Prepare the roof: Clean and prepare the surface according to the manufacturer's requirements.
5. Apply the compatible topcoat: Once the primer system is ready, apply the recommended roof coating in accordance with the product technical data.
