Recommended Uses 

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


Theoretical: 9.8 m²/l at 45 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. For optimum results remove rust, rust scale, mill scale and deteriorated coatings by abrasive blasting to Sa 2½ (ISO 8501-1 : 1988), blast profile max. 50 µm. The surface must be clean and dry during application.
