*****FREE SHIPPING*****

Formerly known as Corotech V330, the Benjamin Moore HP3300 Gloss Direct-to-Metal (DTM) Enamel is a high-performance, waterborne acrylic coating designed to deliver long-lasting protection and a clean, glossy finish on a wide variety of metal and non-metal surfaces. This versatile product is ideal for both interior and exterior applications where moisture resistance, flash rust protection, and easy maintenance are essential.

Engineered for light to moderate industrial environments, HP3300 is perfect for commercial buildings, facilities, and equipment that demand durable and reliable performance. Its advanced formulation prevents flash rusting on ferrous metals, making it a superior choice for direct-to-metal applications.

KEY FEATURES:

• Glossy water-based acrylic finish for professional appearance
• Direct-to-metal (DTM) application—no primer needed on most surfaces
• Highly moisture-resistant for indoor and outdoor environments
• Resists flash rusting on ferrous substrates
• Provides long-term corrosion protection
• Easy water clean-up for reduced downtime

USAGE:

• Interior and exterior applications on:
• Steel, galvanized steel, aluminum
• Masonry, concrete, wood
• Drywall, plaster, equipment, and fixtures

• To touch: 1 hour
• Recoat: 4 hours
• High humidity and cool temperatures will result in longer dry, recoat and service times.

SURFACE PREPARATION: Prior to painting any surface, area must be clean, dry and free of all grease, dirt, dust, oil and wax. Clean all surfaces using HP6000 Oil & Grease Emulsifier. Remove all remaining loose paint, rust and mill scale via Hand Tool Cleaning (SSPC-SP 2) or Power Tool cleaning (SSPC-SP 3). 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.

PRIMER SYSTEMS: 

• Ferrous Metal: Apply directly to properly prepared, ferrous metal surfaces. For additional rust protection, prime with HP1100 Acrylic Metal Primer.
• Galvanized, Aluminum and Non-Ferrous Metals: Clean oil from new galvanized metal by cleaning with HP6000 Oil & Grease Emulsifier. Apply directly to properly prepared, ferrous metal surfaces. For additional rust protection, prime with HP1100 Acrylic Metal Primer.
• Wood: Sand surfaces. Prime bare spots and new wood with an acrylic primer/sealer/undercoater.
• Drywall and Cured Plaster: Sand surfaces. Prime with an acrylic primer/sealer/undercoater.
• Concrete/Masonry: All vertical masonry surfaces must be allowed to cure a minimum of 30 days before painting. Acid etch or abrasive blast all slick, glazed concrete or concrete with laitance. For acid etching, follow all manufacturer’s directions and safety instructions. Smooth surfaces should be coated with a masonry sealer. For rough surfaces, prime with a block filler to produce a smoother finish followed by one or two coats of HP3300 as needed.

APPLICATION: For best results, use a premium nylon/polyester brush or premium roller. Apply paint generously from unpainted areas into wet area. This product can also be sprayed.

• Spray, Airless: Pressure / 1,500 – 2,500 PSI Tip / 0.013 – 0.017 
• NOTE: Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with warm water. No reduction is necessary. 
• Do not apply if material, substrate or ambient temperature is below 50 °F (10 °C).
• Relative humidity should be below 90%.
