Surface Application
Typical Surfaces for Insultec Application
| Surface Type | Primer / Preparation Required Before Applying Insultec |
|---|---|
| New Colorbond® / Galvanised Steel | Suitable etch primer or metal primer recommended prior to application |
| Previously Painted Metal Roofs | Clean thoroughly and ensure existing coating is sound and well adhered. Insulprime may be suitable |
| Concrete Roof Tiles | Insulprime recommended after cleaning and preparation |
| Terracotta Roof Tiles | Suitable tile primer/sealer recommended prior to application |
| Concrete Walls & Masonry | Masonry sealer or Insulprime recommended |
| Rendered Surfaces | Sealer/primer recommended depending on porosity and condition |
| Fibre Cement Sheeting | Suitable acrylic primer/sealer recommended |
| Brickwork | Masonry sealer or suitable penetrating primer recommended |
| Shipping Containers | Etch primer recommended where bare metal is exposed |
| Steel Structures | Industrial metal primer or anti-corrosion primer recommended |
| Tanks & Storage Vessels | Surface-specific industrial primer recommended depending on substrate |
| Timber Surfaces | Suitable timber primer/sealer required before application |
| Plasterboard/Internal Walls | Acrylic sealer undercoat recommended |
| Existing Waterproof Membranes | Compatibility testing and inspection required prior to application |
| Asphalt or Bitumen Surfaces | Specialised bonding primer may be required |
| Marine or Coastal Structures |
Important notes
- All surfaces must be clean, dry, and free from loose material, oil, grease, mould, or contaminants before application.
- Moisture content should be checked on porous surfaces prior to coating.
- Glossy or previously painted surfaces may require sanding or mechanical preparation.
- Primer selection may vary depending on substrate condition, environment, and project requirements.
- Insultec can assist in recommending the most suitable primer system for specific projects and substrates.
