What We Do

One Stop for All Your Coatings Needs

United Coatings was built to give customers a true one-stop service — blast, coat, cure, and ship, all under one roof.

Surface Preparation

Two dedicated blast booths — including a 65' booth with full-floor media recovery — remove rust, mill scale, old coatings, and steel imperfections to give every coating the surface prep it needs to last.

Powder Coating

Superior durability and chip resistance, vibrant long-lasting color, and enhanced corrosion protection — cured in the Northwest's largest powder coating oven at 65 feet.

Learn More →

Industrial Painting

Zinc-rich primers, high-solids epoxies, urethanes, enamels, non-skid coatings, and acrylic/latex systems — heavy-duty protection for the harshest environments.

Learn More →

Duplex Coating

Already galvanized? We sweep blast and apply powder or paint topcoats over hot-dip galvanized steel — the corrosion protection of zinc with the finish your project deserves.

Learn More →

Intumescent Coatings

Shop-applied fire-resistive coatings that expand under fire into an insulating char — rated protection for structural steel with a clean, paint-like finish.
