How To Refinish Wooden Garage Doors

Posted on: 12 May 2016


The garage is a large part of your home style. Since it so large and visible, the garage door should always be kept up. Wooden doors can fade and loose their finish over time. To protect that style and waterproof finish of the wood, you need to refinish it every few years. As long as you keep your garage door waterproof, it will remain strong and colorful. This article explains how to refinish wooden garage doors.

Leaving the Panels Attached 

When refinish wooden garage door panels, you need to decide whether you are going to leave the panels attached or remove them. Of course, removing them, and the having to reattach them, adds some time to the job. The main perk of removing removing the panels is that you can stain them in a controlled area where you can prevent spills. When you stain the panels while they are still attached to the garage, you need to do a lot masking off to protect from spills. However, you can often run into problems when you remove the panel and try to reattach it. Often, the frame will bend and the panel will not fit. To avoid this possible problem, you should just leave the panels as they are and mask off the floor beneath it.

Sanding the Panels

The key to sanding the panels is to use a power sander. You should invest in medium grit (around 60) and extra fine grit (about 400) paper. First use the medium grit to sand down the existing stain. You might also need to use a sponge sander if you have decorative panels with a sunken design. But before you can apply any stain, you need to sand over the surface with the extra fine paper. This makes the wood so it is smooth enough to be painted.

Staining the Panels

Staining the panels is best done with lint free rags instead of a paintbrush. Rags make it easier to control dripping and get an even finish in the crevices of the design. The key is to mix the can of stain and restir it every hour or so. You don't want the dye to sink to the bottom of the can. You most likely need to apply multiple coats for better waterproof protection and a darker stain.

This process is fairly simple, but it takes some time because garages are so large.
