5 Trustworthy Steps for How to Refinish a Wood Garage Door

Here are 5 trustworthy steps for how to refinish a wood garage door:

Step 1: Cleaning

Before starting the refinishing process, it is crucial to clean the surface of the garage doors. Use a mild detergent mixed with warm water and a soft cloth to gently remove dust, dirt, and grime. Clean both the interior and exterior sides of the doors to ensure a thorough cleaning.

Step 2: Sanding

Sanding is an essential step in the refinishing process as it helps to remove any imperfections and create a smooth surface for the new finish.

Be sure to sand in the direction of the wood grain to avoid any scratches or damage.
