Our Facility

About Our Facility

Founded in 1960, Numatic Finishing Corporation has a 21,000 sq. ft. office warehouse and finished area in Auburn, WA, that is fully insured and features sprinklers.

We are fully automated with two flatlines for millwork, an automatic door line with special infrared heat for curing the finish, and two other areas, including one booth for casework and paneling and the other booth for small projects or change orders, known as “hot jobs.” We recently installed a UV cure flatline that enables us to do high-end finishing on flat panels, doors, and door skins.

We are proud members of AWI (Architectural Woodwork Institute) since 1988 and HPVA (Hardwood Plywood & Veneer Association). You will be pleased to know that we’re a drug-free business! Walk-in appointments are welcome.

Finishes & Capabilities

Numatic Finishing Corporation, specializes in applying
finishes onto architectural woodwork, including doors,
millwork, casework and paneling. We provide a wide variety of wood finishes, such as wood treatment, insect treatment, fire treatment, priming, painting, custom staining, and finishes.

We still hand-stain and wipe some projects to bring out the beauty of the wood, and those same custom handfinishes can be matched by our automated lines. We run three types finishing lines; each line is capable of handling very large projects.


Our UV Flatine applies four coats of ultra durable UV coatings, the finish material is HAPs free, and contains zero VOCs. Therefore, no off-gassing occurs, and no curing time is necessary. Once the final coat is applied, your product rolls off the line, ready to ship.

Our Millwork Flatline is capable of producing tens of
thousands of feet, of finefinished product per day.


Our Automated DoorLine features a brand new finishing system that provides a increased production efficiency resulting in a safe, clean, climate controlled environment necessary to achieve the high quality finishes we provide
