Prefinshing with Timberline

At Timberline Industrial Finishing LLC, we believe the best way to protect and showcase wood is to finish it right from the start. Our team has over 15 years of experience in stain and texture application, color development, and factory finishing processes that deliver consistent, high-quality results.
What began as hands-on finishing work has grown into a state-of-the-art operation in San Marcos, where we coat every product under controlled conditions for maximum protection and long-lasting performance.

Why Choose prefinished products?

Quality
Factory finishing provides a level of precision and consistency that on-site finishing simply can’t match. Every piece is sealed on all sides for superior moisture protection and durability. Unlike jobsite painting, where coatings are often applied unevenly, our process applies the full recommended wet mils of coating. Most paint manufacturers recommend 8 wet mils for proper protection—but field application typically delivers only 2–3 wet mils, reducing the lifespan of the finish. In our controlled environment, we consistently apply the full 8 wet mils, ensuring maximum performance and long-lasting protection.

Consistency
Our finishing process ensures coatings are applied at measurable and repeatable film builds, giving you reliable, uniform results across every order.

Cost Savings
Prefinished products save builders and contractors valuable time and labor on-site—reducing callbacks, eliminating weather delays, and lowering total project costs.

Customization
We offer exclusive color palettes for lumber yards and fully custom finishes for builders, creating a unique, one-stop-shop experience that strengthens your competitive edge.

performance benefits

Our knowledge of stains, coatings, and sealers allows us to tailor finishes to meet the specific needs of each project. Multi-coat systems and advanced protective layers ensure our products hold up against Texas heat, UV exposure, and moisture—lasting well beyond industry averages.

Keeping Projects on Schedule

Jobsite finishing often means dealing with weather, labor shortages, and scheduling conflicts. With Timberline Prefinshing, products arrive ready to install after a brief acclimation period. This streamlined process keeps projects moving forward and gives lumber yards and builders one less step to manage.
