Crc 05048 Cold Galvanized Coating Gray 13 Oz

Product Description

The CRC 05048 is a zinc-rich aerosol coating that delivers instant cold galvanizing protection on steel and iron surfaces. Applied directly from the can, it deposits a high-zinc layer that electrochemically protects bare metal against rust and corrosion — functioning similarly to hot-dip galvanizing without heat or specialized equipment. The gray finish blends with standard galvanized surfaces, making it suitable for touch-up and repair work. HVAC installers, plumbers, electricians, and sheet metal workers keep this product on hand for field repairs to cut edges, welds, drilled holes, and abraded coatings on galvanized ductwork, pipe hangers, conduit fittings, and structural supports.

This coating is used wherever bare or damaged steel needs rapid corrosion protection in the field. Common applications include touch-up of galvanized ductwork after cutting or drilling, protection of exposed metal on pipe hangers and strut, repair of scratched or abraded coatings on HVAC equipment panels, and general corrosion prevention on ferrous surfaces in both residential and light commercial installations. The aerosol format allows fast, even coverage in tight spaces without brushes or additional equipment.

Key Features

• Zinc-rich formula provides electrochemical corrosion protection on steel and iron
• Gray finish closely matches standard hot-dip galvanized surfaces for clean touch-up results
• Aerosol delivery allows one-hand application in confined or overhead spaces
• No heat or specialized equipment required — applies at ambient field conditions
• Suitable for cut edges, welds, drilled holes, and abraded galvanized coatings
• 13 oz net weight per can provides extended field use

Compatibility

Designed for use on bare, cut, or damaged steel and iron surfaces as an OEM-style cold galvanizing touch-up coating. Typical applications include galvanized ductwork, pipe hangers, conduit, strut channel, and structural steel in HVAC, plumbing, and electrical installations.

Installation Notes

Application is performed by licensed tradespeople or qualified technicians as part of standard field finishing and corrosion-prevention procedures. Shake the can thoroughly before use and apply in a well-ventilated area. Keep away from open flames and ignition sources during application, as aerosol propellants are flammable. Allow the coating to dry fully before covering or insulating treated surfaces.
