Remove Mildew From A Wooden Garage Door And Protect Its Surface

If your garage has a wooden door and mildew is on its exterior, learn how to treat it with the following steps. Once the mildew has been eliminated, protect the door from additional damage by adding a coat of sealer to it.

Materials

  • dust mask
  • rubber gloves
  • bleach
  • white vinegar
  • water
  • bucket
  • scrub brush
  • soapy water
  • sponge
  • water hose
  • wood sealer (for exteriors)
  • paint tray
  • paint roller
  • roller frame
  • tarps

Remove The Mildew And Clean The Door's Surface

Secure the garage door so that it doesn't open while you are removing the mildew. Put on a dust mask and rubber gloves so that you do not breathe in the odor that the mildew emits or expose your hands to the cleaning solution. Add equal parts of white vinegar, bleach, and water to a bucket. Dip a scrub brush in the cleaning solution and press down firmly on it as you rub it over each stained area on the door. Move the brush back and forth in straight lines.

After the mildew has been eliminated, clean the entire door's surface off with soapy water and a sponge. Rinse the door off with a water hose and wait for it to dry. The wood will lighten in color when this occurs.

Add Wood Sealer To The Door

Lay a couple tarps in front of the door to protect the ground as you are applying the sealer. Some sealers have added pigment to them and others are clear. Select the type that you prefer and make sure that it is designed for exteriors. The sealer will prevent moisture from damaging the wood and causing mildew to form. Pour the sealer into a paint tray. Use a paint roller to apply a thin, even coat of the sealer in straight lines, beginning in one of the top corners of the door and moving the roller downwards.

After the door is covered with sealer, wait for it to dry. This may take several hours and is highly dependent upon the current weather conditions. Add a second coat of sealer to the door in the same manner. After the sealer has dried, the door will be protected each time that it rains. The sealer will cause water to bead up on the door's surface and roll downwards. Keep the door maintained in the future by removing surface stains with mild detergent and rinsing the surface off with a water hose. The sealer will protect the door for several years.

Contact a local garage door company, like Doors/Windows Unlimited Inc, if you have further maintenance concerns.
