Paint and coatings protect equipment, mark hazards and keep facilities looking maintained. This subcategory includes aerosol spray paint, inverted marking paint for ground and layout work, primers, industrial enamels, cold galvanizing compound, high temperature paint, and specialty coatings such as rust converters and clear coats. Maintenance crews use them for touch-up on machines and railings, contractors use them for layout and locating, and fabricators use them on finished parts.

What to check before you order

  • Surface and primer. Bare steel, galvanized metal, aluminum and concrete each need a suitable primer. Read the topcoat label for compatible primers.
  • Service conditions. Choose high heat paint for exhaust and hot surfaces, and coatings rated for outdoor or wet exposure where needed.
  • Marking paint. Inverted marking paint sprays upside down. Choose colors that match the APWA uniform color code when marking utilities, and follow your local one-call rules.
  • Safety colors. OSHA and ANSI standards assign colors such as safety yellow and safety red to specific hazards and equipment. Follow your site's safety program.
  • Ventilation and storage. Aerosols and solvent-based coatings are often flammable. Read the SDS for ventilation, PPE and storage.

Apply your coatings with brushes, rollers and supplies, find paint markers under marking tools, or see all of Paint & Marking.

Common questions

Can you paint galvanized steel?

Yes, but the surface must be cleaned of oils and residue first, and the primer or paint must be labeled for galvanized metal. Some alkyd oil-based paints react with zinc and peel, so read the label before coating galvanized railings, ductwork or panels.

What is cold galvanizing compound used for?

Cold galvanizing compound is a zinc-rich coating that protects steel the way galvanizing does, with the zinc corroding before the steel. It is used to touch up welds, cut ends and damaged hot-dip galvanized surfaces, though it is not the same as a hot-dip galvanized finish.
