Factory Finishing Systems FAQs
What are factory finishing systems?
Factory finishing systems are coatings and surface treatments applied to wood products before they arrive at the jobsite. Rex Lumber offers factory-applied primers, stains, lacquers, varnishes, topcoats, and specialty coatings designed for architectural wood products, millwork, siding, decking, trim, and other commercial applications. By applying these finishes in a controlled manufacturing environment, Rex helps customers receive production-ready materials with consistent coating quality and reduced onsite preparation.
What are the benefits of factory-applied finishes?
Factory-applied finishes help improve coating consistency while reducing the time and labor required at the jobsite. Depending on the finishing system, benefits may include improved adhesion, more uniform coverage, enhanced substrate protection, smoother finishes, and greater production consistency. Receiving wood products that are primed, stained, or coated before delivery also helps manufacturers, contractors, and millwork professionals streamline installation and maintain quality across large production runs.
Can Rex Lumber match custom colors?
Rex Lumber offers factory-applied finishing systems in a wide selection of Benjamin Moore® and Sherwin-Williams® stock colors. For projects requiring custom finishes, color matching assistance is available through ML Campbell finishing systems, and sample production may be available depending on the project’s complexity. Our team works with customers to identify the most appropriate finishing system for their application and performance requirements.
What wood species can be factory finished?
Rex Lumber’s factory finishing systems are designed to support a wide variety of wood species and applications. Depending on the coating system, factory finishing is available for products including Accoya®, Western Red Cedar, Cypress, Sapele, Mahogany, Ipe, Cumaru, Kebony®, and thermally modified wood. These systems are commonly used for siding, trim, mouldings, decking, cladding, porch flooring, millwork, and other architectural wood products.
Do factory-applied coatings reduce installation time?
Yes. Factory-applied coatings help reduce onsite finishing work by delivering wood products that are primed, stained, or coated before they reach the jobsite. This can reduce field labor, improve installation efficiency, and help keep projects on schedule. By applying coatings in a controlled manufacturing environment, Rex Lumber also provides consistent finish quality that supports more predictable project outcomes.
