Benefits Of Pre-Finishing
Built to Last
Factory-Applied Perfection
Our full encapsulation process seals all sides, protection against moisture intrusion, fading, cracking, and weather-related damage.
Every piece is coated in a controlled, factory environment - delivering unmatched consistency, coverage, and professional-grade results on every board.
Faster Installation
Seamless Service
Pre-finished materials arrive ready to install, eliminating on-site painting and reducing labor time, delays, and overall project costs.
We don’t just coat - we install. One team, one process, complete accountability from preparation to final installation.
Grand Finishes LLC applies our coatings in a controlled environment, delivering consistent coverage, faster installation timelines, and long-term durability that often outperforms traditional field-applied finishes. Prefinished materials arrive job-site ready, helping contractors reduce labor time, minimize weather delays, and lower overall project costs.
