Crc Industries 5048 Cold Galvanizing Compound Spray 13 Oz

Product Description

The CRC INDUSTRIES 5048 is a cold galvanizing compound in a 13 oz aerosol spray can that delivers galvanized-level rust and corrosion protection without the heat or equipment of a hot-dip galvanizing process. The formula contains 95% pure zinc, which bonds to metal surfaces and actively inhibits rust through sacrificial zinc protection. The result is a smooth, matte gray coating that dries to the touch in 15 minutes. It is used by HVAC technicians, plumbers, electricians, and general contractors to protect ferrous metal components, fasteners, conduit, pipe hangers, and structural steel from corrosion in the field.

This product is suited for both shop and job-site use in residential and commercial applications. It applies directly to cleaned bare metal, freshly cut galvanized steel, welds, abraded or damaged galvanized surfaces, and other metal substrates that need immediate corrosion protection. The spray format makes it practical for touch-up work, field repairs, and hard-to-reach areas where brush or dip application is not feasible.

Key Features

• 95% pure zinc content provides sacrificial corrosion protection comparable to hot-dip galvanizing
• Aerosol spray format allows quick, even application in the field without specialized equipment
• Dries to the touch in 15 minutes for fast return to service
• Forms a tough, flexible matte gray finish that resists chipping and cracking
• 13 oz can covers a broad work area per unit

Compatibility

Designed for application on ferrous metals, galvanized steel repair areas, welds, cut edges, and similar bare metal surfaces requiring corrosion protection in trade and industrial settings.

Installation Notes

Surface preparation is critical before applying any cold galvanizing compound. Remove loose rust, scale, grease, and contaminants using wire brushing, grinding, or sandblasting to bare metal prior to application. Use in well-ventilated areas and follow all label safety guidance for aerosol handling. This product is applied by the installing trade professional as part of a corrosion protection or repair workflow.
