How is factory prefinishing different from field finishing?

Field finishing is done on-site after installation, using brushes, rollers, or portable spray equipment. Factory prefinishing is applied before installation using automated coating lines in a temperature- and humidity-controlled facility. Factory prefinishing produces more consistent results, cures faster, generates fewer VOC emissions on-site, and reduces labor costs.

What types of products can be factory prefinished?

Most wood and engineered wood products can be factory prefinished, including interior and exterior doors, crown molding and baseboards, window and door casing, shiplap and wall paneling, engineered wood, fiber cement siding, stair treads, risers, handrails, and balusters. If your product is made of wood or a wood-based composite, it can likely be factory prefinished.

What finishes are available for factory prefinishing?

Common factory-applied finishes include UV-curable clear coats (the fastest cure time), UV-curable paints, water-based paints and stains (low VOC), and custom color-matched coatings. The best finish depends on your substrate, end use, and performance requirements.

Is factory prefinishing more expensive than field finishing?

In most cases, factory prefinishing is less expensive on a total-cost basis. While the per-unit material cost may be similar, factory prefinishing eliminates on-site labor, reduces project timelines, and minimizes rework from inconsistent field application. For high-volume production, the cost savings are significant.

How long does factory prefinishing take?

Production timelines vary by volume and finish type. UV-curable coatings cure in seconds, allowing same-day processing. Water-based finishes require longer dry times but are still faster than field finishing. Typical turnaround from order confirmation to shipment is 2 to 3 weeks for standard runs.

Does factory prefinishing meet LEED requirements?

Yes. Factory prefinishing supports LEED certification in several ways: low-VOC and zero-VOC coating options reduce indoor air quality impact, controlled application reduces material waste, and UV-curable finishes produce near-zero VOC emissions. Woodco provides documentation to support your project's green building certification.

Can factory-prefinished products be touched up after installation?

Yes, though touchups are rarely needed. Factory-applied finishes are more durable and consistent than field finishes, so damage during handling is uncommon. When touchups are necessary, we provide color-matched touch-up kits and instructions for your installers.

What is the minimum order for factory prefinishing?

Woodco works with projects of all sizes, from one-time orders of a few hundred pieces to ongoing production runs of 10,000+ pieces per year. There is no strict minimum. Contact us to discuss your specific needs and we'll provide a custom quote.

How do I get started with factory prefinishing?

Start by submitting a quote request with your product type, substrate, desired finish, and estimated volume. Our team will review your specs, recommend a coating system, and send you sample boards for approval. From first contact to production, the process typically takes 2 to 4 weeks.

Why Factory Prefinishing?

Factory prefinishing replaces on-site painting with controlled, automated coating, delivering better quality, faster timelines, and lower total cost. Here's why manufacturers, retailers, and developers are making the switch.

What Is Factory Prefinishing?

Factory prefinishing is the process of applying paint, stain, or clear-coat finishes to wood products at a controlled manufacturing facility before they are shipped to the job site. Products arrive ready to install with no field finishing required.

Instead of hiring painters to apply coatings on-site, where dust, humidity, temperature, and human variability affect the result, factory prefinishing uses automated coating lines in a controlled environment. The result is a more consistent, more durable finish at a lower total cost.

Woodco Prefinishing operates a 50,000 sq ft facility in Blaine, MN equipped with UV-curable and water-based finishing systems. We prefinish doors, millwork, siding, paneling, stair parts, and custom products for manufacturers, retailers, and commercial developers nationwide.

Whether you're a door manufacturer running 10,000 units a year or a contractor specifying trim for a single hotel renovation, factory prefinishing gives you a consistent product, faster install, and one less trade to coordinate on-site.

Prefinished vs. Field-Finished: What's the Difference?

Factor	Factory Prefinished	Field Finished
Color consistency	Automated, piece-to-piece uniformity	Varies by applicator and conditions
Labor cost	Included in unit price	Separate on-site trade required
Dry / cure time	Seconds (UV) to hours (water-based)	24 to 72 hours on-site
VOC emissions on-site	Zero, applied off-site	Significant, paints and stains cure indoors
Rework risk	Low, controlled environment	High, dust, humidity, temperature
Material waste	Minimal, automated application	Higher, overspray, drips, touchups
LEED compliance	Supports credits (low-VOC, reduced waste)	Difficult to document and certify

Benefits of Factory Prefinishing

Consistent Color Quality

Automated coating lines deliver piece-to-piece color uniformity that hand application can't match. Every board, door, and trim piece arrives at the same spec.

Reduced Job-Site Labor

Eliminate the need for on-site painters and the coordination overhead that comes with them. Products arrive finished and ready to install.

Faster Project Timelines

UV-curable finishes cure in seconds, not days. Prefinished materials can be installed immediately, compressing your project schedule by weeks.

Lower VOC Exposure On-Site

All coating and curing happens at our facility, not yours. This means zero paint fumes during construction, better air quality, and fewer health and safety concerns.

LEED Compliance Support

Our low-VOC and UV-curable coatings support green building certifications. We provide documentation for LEED credit submissions.

One Vendor, One Responsibility

When Woodco prefinishes your product, the finish quality is our responsibility, not a subcontractor's. One point of contact, one quality standard.

How the Process Works

1
Submit your product specs and finish requirements
Tell us what you're building, the substrate, desired color or finish, and approximate volume. We'll review your specs and recommend the right coating system.
2
Receive a sample kit and review finish options
We'll prepare sample boards or sticks with your requested finish for your approval. You can evaluate color, sheen, and texture before production begins.
3
Confirm your order and production schedule
Once samples are approved, we lock in your order details and schedule production to align with your delivery timeline.
4
Woodco factory-prefinishes your products
Your products are coated in our controlled 50,000 sq ft facility using automated UV-curable or water-based systems, depending on your spec.
5
Delivery to your facility or job site
Finished products ship directly to your warehouse, distribution center, or job site, ready to install with no field finishing required.
