Repairing cabinet doors is an intricate process that needs a bit of planning. As such, while planning for a repair, the first step should be to prepare the cabinets for the job.

Application of Primer

The application of a primer provides a smooth and even surface for painting your kitchen cabinet. The process involves scraping peeling paint from the door’s surface in preparation for applying a shellac-based primer.  This wood-based primer is available in most local hardware shops.

It can remove blemishes, evens out the surface, and allows your paint to stick. It also comes in a spray bottle that is ready to use. Apply one or two coats over the damaged areas allowing each coat to dry before the next.

Sanding the Cabinet Door

Sanding down your damaged kitchen door will remove excess wood filler to make the surface of the wood appear even and without swollen areas or bubbles. Once the primer feels dry to the touch, the next step should be to sand the affected area to a smooth finish. You can use 120-grit sandpaper by hand, but it will be much easier using an electric sander. Do not sand too much to avoid removing the primer. Applying too much pressure can also burn the surrounding wood and ruin the look of your cabinet door permanently. Otherwise, make sure it’s smoother, and the damages are no longer visible.


Choose the same type and color of paint used to finish the kitchen cabinet originally. You may use a brush if the surface is small or a roller if it is larger, then finish off the minor details with a paintbrush.  Sand gently using 220-grit sandpaper until you have the entire surface smooth. Sanding helps to create tiny grooves upon which your final coat will adhere properly. Your kitchen cabinet door will now look as good as new.
