SURFACE PREPARATION: Prior to painting any surface, remove all grease, dirt and other surface contamination by applying a solution of Corotech® Oil & Grease Emulsifier V600. Remove all remaining loose paint, rust and mill scale via Hand Tool Cleaning (SSPC-SP2) or Power Tool cleaning (SSPC-SP3). Fill holes and cracks and sand smooth. Glossy surfaces must be fully deglossed. Moderate to heavily rusted areas must be thoroughly prepared and active rust should be properly removed. When using COMMAND® over caulk, test a small area and check after approximately 30 minutes for compatibility before painting the entire surface. 

• FERROUS METALS: Remove any active rusted areas according to the surface preparation instructions. Apply one coat of Corotech® Acrylic Metal Primer V110 prior to top coating.
• NON-FERROUS METALS (Galvanized & Aluminum): Galvanized steel normally comes from the mill chemically treated or passivated, to prevent white rusting or oxidation of the galvanized surface during the time it is being stored or shipped to the job site. Due to this, the surface must be thoroughly cleaned with Corotech® Oil & Grease Emulsifier V600 or solvent wiping in accordance with SSPC-SP1 prior to coating. Prime properly prepared surfaces with Acrylic Metal Primer V110, Waterborne Bonding Primer V175 or apply 1-2 coats of COMMAND® direct.
• WOOD SURFACES: For best results, prime bare spots and new wood with a quality acrylic primer. Apply one or two finish coats of COMMAND® as needed. COMMAND® can also be used as a selfsealing topcoat, however, may dry to an uneven finish on some species of wood.
• DRYWALL & PLASTER: Prime new drywall and fully cured plaster with a quality acrylic primer. Apply one or two finish coats as needed. 
• CONCRETE: Allow new concrete to age for a minimum of 30 days. New or old unpainted concrete should be etched with a concrete etch solution and then rinsed thoroughly with water. Be sure to follow the manufacturer's instructions when mixing and using solution. (Protect skin and eyes by wearing rubber gloves and goggles.) Rinse surface thoroughly with clean water. Allow surface to dry completely before coating. Old painted concrete should be fully cleaned and sanded if necessary.
• GLOSSY SURFACES/ALKYD FINISHES: Glossy surfaces and/or existing alkyd finishes, must be deglossed to obtain a surface profile prior to coating. The preferred method is thoroughly sanding the surface area. Areas that cannot be properly deglossed should be primed with Corotech® Waterborne Bonding Primer V175 prior to finish coating.

APPLICATION:  Mixing of Paint: Stir thoroughly before and occasionally during use. For best application results, apply generously going from unpainted into painted areas. Thin with sparingly with water if needed.

• Airless Spray: Tip range between .015 and .019. Total fluid output pressure at tip should not be less than 2400 psi.
• Air Spray (Pressure Pot): DeVilbis MBC or JGA gun, with 704 or 765 air cap and Fluid Tip E.
• Brush: Synthetic Bristle only.
• Roller: ½” nap or finer for smooth surfaces.

NOTE: Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with recommended thinner. Do not apply if material, substrate or ambient temperature is below 35 °F (1.7 °C). Relative humidity should be below 90%. Do not apply if within 5 degrees of dew point or if rain is expected within 4 hours of application.
