SURFACE PREPARATION: All grease, oil, dirt, mildew, or any other surface contaminants must be removed using HP6000 Oil & Grease Emulsifier or SSPC-SP1 solvent cleaning.
- Ferrous Metal: All loose rust and mill scale should be removed prior to applying this product. A minimum of SSPC-SP6 Commercial Blast or abrasive blasting is recommended for severe environmental exposures. Small areas may be cleaned in accordance with SSPC-SP2 Hand Tool Cleaning or SSPC-SP3 Power Tool Cleaning or SSPC-SP13 Power Tool Cleaning to bare metal. Tightly adhering rust may be coated over provided the surface is intended for use in mild atmospheric exposures.
- Non-Ferrous Metal (Galvanized, Aluminum, etc.): Remove surface contaminants using HP6000 Oil & Grease Emulsifier or SSPC-SP1 solvent cleaning.
- Previously Painted Surfaces: Clean using HP6000 Oil & Grease Emulsifier or solvent washed as outlined above. Dull glossy surfaces by sanding. Remove all loose, flaking or peeling paint prior to application.
APPLICATION: Stir thoroughly before and occasionally during use. Thinning is not required although a small amount of water (up to 8 fl. oz. per gallon) may be added for preferred application properties. For best results, use a premium nylon/polyester brush, roller, or a similar product. This product can also be sprayed.
