7 Steps to Fixing Your Peeling Garage Door

weather stripIf you have a painted steel garage door you may, at some point find the paint starts to peel from the surface. Unlike wooden surfaces, steel doesn’t accept paint readily and if the wrong type of paint was used, or the garage door surface wasn’t prepared sufficiently, the paint can eventually lose adherence. However, although unsightly, it’s not the end of the world and you can easily patch up your paintwork and have the door looking attractive again.

7 Simple Steps to Fix That Peeling Paintwork

Before getting under way with the steps to fix your steel door paintwork, here are the items you’ll need:

  • Paint roller and tray
  • Paint brush
  • A pair of rubber gloves
  • Putty knife
  • Trisodium phosphate
  • Medium grade sandpaper
  • A sponge and a cloth
  • A garden hose
  • Acrylic-latex exterior garage door paint
  • Steel primer

Step 1: Use your metal putty knife to scrape all peeling, bubbling or chipped paint from the surface of the door.

Step 2: Use the sandpaper to roughen up the bare door surface in the areas where you scraped the paint away.

Step 3: Using a solution of two gallons of warm water with 1/3 of a cup of trisodium phosphate added, wash the door down with the sponge. This is where you need to have the rubber gloves on, to protect them from the soap solution.

Step 4: Rinse the door down using the garden hose.

Step 5: Use your clean, dry cloth to wipe all moisture from the bare areas of the door.

Step 6: Coat the bare areas of the door with the steel primer. Give the primer at least a couple of hours to dry before continuing with the next step.

Step 7: Finally, paint the entire garage door with a coat of acrylic-latex exterior paint, using the roller and tray.

An Extra Tip

Before you carry out step 7, it can be a good idea to test the exterior paint on a small section of the door. Just use your paint brush to apply a small square of paint. Leave it to dry for a couple of hours and then stick a strip of masking tape to the test square and peel it off again immediately.

If the paint comes away from the door on the masking tape, you will know that is hasn’t “taken” and will peel again or bubble after you have painted the whole door. The reason for the paint failing to stick is probably one of the following:

  • Outside air temperature is too warm or cool
  • The air is too humid
  • You have tried to use the wrong kind of paint

Take a look on the paint can to find the temperature range recommended for applying the paint. If the actual air temperature is outside of the stated range, wait until the temperature is correct and test once more. If the paint comes away a second time when you apply tape to it, you should probably get some advice from the store where you bought the paint.

By following the seven steps above, you can soon have your peeling steel door looking great again and adding to the curb appeal your home deserves.
