Paint Type
Polyurethane Paint
Polyurethane paint is a resin-based coating that forms a durable finish, with formulas ranging from clear wood coatings to pigmented industrial systems.
Polyurethane paint surface compatibility
Polyurethane coatings protect prepared wood and concrete; metal and fiberglass need a system made for each substrate, with compatible primers and curing.
| Surface | Compatibility | Preparation | Primer | Finish | Guide |
|---|---|---|---|---|---|
| Wood | Excellent with a wood polyurethane or approved coating system | Remove wax, grease, and loose finish; sand as directed and remove all dust. | Clear wood polyurethane may be applied to bare or stained wood; pigmented systems are product-specific. | Smooth, durable clear or colored finish available in multiple sheens. | — |
| Concrete | Excellent with a concrete or floor-rated urethane system | Allow new concrete to cure, test moisture, and remove laitance, curing compounds, grease, and loose coating. | Use the specified concrete primer or base coat. | Hard-wearing finish with resistance determined by the complete system. | — |
| Steel and metal | Excellent with an industrial or direct-to-metal urethane | Remove rust, mill scale, grease, and loose coating, then create the required surface profile. | Use the specified corrosion-resistant primer unless direct-to-metal application is approved. | Durable topcoat with good color and gloss retention in suitable systems. | — |
| Aluminum | Good when the system expressly approves aluminum | Remove oxidation, clean and degrease, then abrade or pretreat as specified. | Use an aluminum-compatible primer unless the coating is approved for direct application. | Protective finish for interior or exterior exposure as rated. | — |
| Fiberglass | Good with a compatible industrial, marine, or specialty system | Remove wax and contamination, sand as directed, and eliminate all dust before coating. | Use the system's fiberglass-compatible primer when required. | Durable finish whose flexibility and exposure rating depend on the selected formula. | — |
| Stainless Steel | Good as part of an approved metal system | Clean and prepare the stainless steel to the coating manufacturer's specified standard. | Usually applied over a compatible primer rather than directly to smooth stainless steel. | Choose a finish rated for the expected wear, chemicals, weather, and cleaning. | — |
| Galvanized Steel | Good as part of an approved metal system | Clean and prepare the galvanizing to the coating manufacturer's specified standard. | Apply over the compatible primer or intermediate coat required by the system. | Choose a finish rated for the expected wear, chemicals, and weather. | — |
| Drywall | Limited to specialty systems that approve prepared drywall | Repair defects, sand smooth, remove dust, and ensure the wall is clean and dry. | Use the exact primer required by the specialty coating. | Primarily for demanding commercial or industrial environments rather than ordinary walls. | — |

Painters who used polyurethane paint
Profiles document urethane and polyurethane in paintings and sculpture on paper, clay, aluminum, and shaped panels, including industrial finish systems.
-
Carroll Dunham
MoMA records urethane paint in Carroll Dunham’s Ship and an untitled 2003 work on paper. These entries distinguish urethane from synthetic polymer paint and show the coating in both a constructed painted object and a more conventional support.
-
Frank Stella
Frank Stella’s 1985 Gobba, zoppa e collotorto uses urethane enamel alongside oil, fluorescent alkyd, and acrylic on etched magnesium and aluminum. The Whitney’s exact term keeps this industrial finish specific rather than reducing it to generic polyurethane.
-
Tom Holland
Tom Holland applies acrylic urethane to clay works, while his epoxy paintings use aluminum. The Whitney identifies the urethane finish, tying it to sculptural forms rather than flattening his varied coatings into a single surface treatment.
-
Roy Thurston
Roy Thurston applies pigmented acrylic polyurethane to hand-milled aluminum panels, then textures and burnishes surfaces to catch shifting light. Museum records link the coating to reflective color fields and depth, connecting an industrial finish with Light and Space concerns.

Chris Berry
Chris Berry demonstrates waterborne two-component polyurethane as a protective finish system, explaining its separate components and application. His profile places this coating alongside house paint and epoxy floors, distinguishing specialized finish work from ordinary latex wall paint.
