Which tool is commonly used to apply a wood finish to surfaces?

• A. Hammer
• B. Chisel
• C. Rasp
• D. Brush

Answer: (D)

Spreading a protective wood finish evenly over a surface relies on an applicator that can hold and release liquid coatings smoothly. A brush is designed to do that, stacking and releasing finish in a controlled film as you work. It lets you reach edges, corners, and along the grain with consistent coverage, which is essential for a uniform, durable finish. Different finishes—varnish, polyurethane, shellac, or stain—are applied with a brush to create a protective layer and enhance the wood’s appearance, making the brush the most practical and common tool for this job. In contrast, a hammer drives fasteners, a chisel cuts and pares wood, and a rasp shapes or smooths surfaces, none of which are used to apply finishes. Use the right brush size and type, work with the grain, and apply thin, even coats for the best result.
