    How To Fix Dented Garage Door

    A dented garage door not only affects the aesthetic appeal of your home, but it can also affect its functionality. Luckily, repairing a dented garage door can be a straightforward DIY project, provided you have the right tools and guidance. In this guide, we’ll walk you through the steps to fix your dented garage door, making it look as good as new.

    Step-by-Step Guide to Fixing a Dented Garage Door

    1. Gather Necessary Tools and Materials

    • Auto body filler
    • Sandpaper (120-grit and 240-grit)
    • Rubber mallet
    • Soft cloth
    • Paint and primer
    • Putty knife

    2. Clean the Area Begin by cleaning the dented area with a soft cloth to remove any dirt or debris.

    3. Pop Out the Dent For minor dents, try to pop them out using a rubber mallet. Gently tap the dented area from the inside of the door to push it out.

    4. Sand the Dented Area Use the 120-grit sandpaper to sand the dented area. This will help the auto body filler adhere better.

    5. Apply the Auto Body Filler Using a putty knife, apply a thin layer of auto body filler over the dented area. Let it dry according to the manufacturer’s instructions.

    6. Sand Again Once the filler is dry, use the 240-grit sandpaper to sand it smooth.

    7. Prime and Paint Apply a layer of primer over the repaired area. Once dry, paint it to match the rest of your garage door.
