What is the first step before finishing a cabinet?

The first step before finishing a cabinet is sanding. Sanding is crucial because it prepares the surface of the wood for finishing by creating a smooth, even surface. This process not only removes any rough spots or imperfections, but it also opens up the wood grain, allowing the stain or finish to penetrate more effectively. A well-sanded surface will enhance the adhesion of paints, stains, or sealants, leading to a more uniform and visually appealing final product.

Skipping this step can result in a poor finish, where the stain may not absorb evenly, or the paint could peel or chip away due to insufficient adherence. Therefore, ensuring that surfaces are properly sanded before moving on to fillers, hardware installation, or the application of any finish is essential to achieving a high-quality result in cabinet building.
