Rust-Oleum Heat Resistant System Aluminium Topcoat 4215 is based on a silicone modified alkyd resin. 

Recommend Uses 

Rust-Oleum 4215 should be used on new, bare steel or blasted steel surfaces primed with Rust-Oleum 4268 Orange Primer
Rust-Oleum 4215 is intended for brush and roller application and can also be applied by spray.
Rust-Oleum 4215 provides heat resistance up to 425°C dry heat in sheltered or interior environments, if applied on Rust-Oleum Heat Resistant System 4268 Orange Primer.
On blasted steel two coats of Rust-Oleum Primer 4268 should be applied prior to the application of Rust-Oleum Aluminium Topcoat 4215


Theoretical: 16.0 m²/l at 15 µm dry 
Practical: Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application. 

Surface Preparation

Remove grease, oil and all other surface contaminations by alkaline or high pressure (steam) cleaning in combination with appropriate detergents. Prime with the recommended Rust-Oleum Orange Primer 4268. Sand previous coatings which are in good condition to roughen the surface slightly. The surface must be clean and dry during application. 

Please read data sheets carefully prior to application.
