The precise chemistry of transforming raw timber into finished furniture
In short: Wood finishing is more than just applying color; it is a systematic process of preparation, conditioning, and protection. Expert Bruce Johnson demonstrates how to achieve professional results on both new and salvaged pieces.
To prepare wood for a finish, the surface must first be leveled with 150-grit sandpaper to remove nicks and open the grain, followed by a tack cloth to eliminate dust. A critical intermediate step is applying a wood conditioner, which ensures the stain absorbs evenly across the timber.
