How to Finish Underside of Kitchen Cabinets

When renovating your kitchen, it’s essential to pay attention to every detail, including the underside of your kitchen cabinets. While the underside may not be as visible as the front, it still contributes to the overall aesthetics of your kitchen. Here’s a step-by-step guide on how to finish the underside of your kitchen cabinets and transform them into a polished and complete look.

Step 1: Clean and Prepare
Start by thoroughly cleaning the underside of your kitchen cabinets. Remove any dust, dirt, or grease using a mild detergent and warm water. Once the surface is clean and dry, sand it lightly to smooth out any imperfections.

Step 2: Choose a Finish
Decide on the type of finish you want for the underside of your kitchen cabinets. You can choose between paint, stain, or clear coat, depending on your desired look and the material of your cabinets. Consider the color scheme and style of your kitchen when making your decision.

Step 3: Apply Primer
If you decide to paint or stain the underside of your kitchen cabinets, it’s essential to apply a primer first. A primer helps the paint or stain adhere better and ensures a more durable finish. Apply the primer evenly using a brush or roller and let it dry according to the manufacturer’s instructions.

Step 4: Paint or Stain
Once the primer is dry, it’s time to apply the paint or stain of your choice. Use a brush or roller to apply an even coat, following the grain of the wood if you’re staining. Allow the first coat to dry completely before applying a second coat for better coverage.

Apply the clear coat with a brush or roller, following the manufacturer’s instructions, and let it dry completely.
