How To Repair Minor Cosmetic Damage To Your Wood Garage Door

Minor damage, such as small cracks and holes, can have a huge impact on the way your wood garage door looks. Thankfully, repairing this type of minor cosmetic damage can be much easier than many homeowners realize. In fact, even the most novice DIY enthusiast will be able to complete this job without the need to hire a professional contractor. The step-by-step guide below can help you to accomplish this task.

Step 1: Gather The Necessary Supplies

While you will not need any highly specialized tools in order to complete this job, you will need a few things that you may not have lying around the house. In order to ensure you are prepared to complete the repair process from start to finish, begin by collecting the following supplies before tackling the actual repair.

  • wood putty
  • rotary tool
  • fine grit sandpaper
  • two clean paintbrushes
  • putty knife (make sure it is the right size for the damage you will be repairing)
  • wood stain or paint that matches your door's finish

Step 2: Clean Away Any Debris

Any debris that is left in or around the damaged areas of your door could potentially mix with your wood putty and prevent it from creating a durable repair patch. Therefore, you will need to take special care to ensure all debris is cleared away before filling in the damaged areas. This should be done by first using a rotary tool to reach deep inside the damaged areas and gently sand away any splintered wood or other debris.

Once the inside of the damage is cleaned, you will need to use a piece of fine grit sandpaper to remove any debris from the area surrounding the damage. Finally, use one of your clean paintbrushes to wipe away any sawdust or other loose particles that settle on your garage door.

Step 3: Fill In The Damaged Areas

Using your putty knife, fill each crack and hole in your garage door with wood putty. Be sure to apply a small amount of putty at a time so that you can push the putty deep into the damaged area. This will allow you to create the most durable repair patch possible.

Once each crack is filled completely, use the edge of your putty knife to smooth out the surface of the repair patch and remove any excess putty. Now simply allow the putty to dry overnight before moving on to the final step.

Step 4: Touch Up The Door's Finish

In order to fully restore the cosmetic appearance of your garage door, you will need to apply a new coat of wood stain or paint. If you are able to find an exact color match, you will be able to simply paint or stain the area that has been repaired. However, if you are unable to match the existing color of your door, you will need to paint or stain the entire door in order to achieve a uniform appearance.

Just A Reminder

This repair process is designed to help you repair cosmetic, not mechanical damage to your wood garage door. If you are experiencing any issues with the way your door functions, you will need to seek out the services of a professional repair contractor in order to ensure that this damage is repaired correctly and that your door is safe to use.
