How To Paint A Garage Door Using The Best Paints?

When it comes to painting a garage door you need to make sure you apply the best paint for the job. The majority of garage doors in the UK are metal and should be prepared so your new coat of paint will last the test of time.

A good garage door paint should dry extremely hard and create a sheen that helps with rust by creating a barrier for year-round elements and bad weather.

Preparing Your Garage Door For Painting

Before painting your garage door you “MUST” remove any sheen from the original paint.

You must not paint over a high sheen paint because you will find after a few weeks it will start to bubble and peel away.

Garage Door Painting - Example

Use a sand pad or a sanding block to take the sheen away and dull the original paint. You can take it back to the steel if you want a rock-solid paint job, but this will take time.

We would advise you to take away the sheen and create a key so the new garage paint will grip and set rock hard.

  1. Use rough grade sandpaper to score and dull the original paint
  2. Once you have sanded your garage door paint check for rust
  3. If the rush is flaking then remove any loose flakes
  4. Apply red oxide paint to the affected area

Use Red Oxide Paint

If your garage door is old and has more than one rust spot then I would suggest you cover your garage door in red oxide.

Red oxide acts as a primer, but more importantly, stops the rust from spreading and reduces any more rust from taking hold of your garage door.

  • Prevents rust
  • Easy to apply
  • Reduces moisture
  • Protects from bad weather

Best Red Oxide Paint (Rustins Metal Primer)

They provide a litre tin @£13 – 15 which is enough to cover your garage door back to front!

It’s a quick quick-drying formula so you can apply this stuff and start applying your garage paint about 60-90 minutes after applying.

But this depends on the weather on hot days it will dry much faster!

Applying Garage Paint

Once your red oxide paint has dried and you are happy you have covered all rust spots if any, then now is the time to prepare to start painting.

You can use a brush and a roller when painting your garage door.

  • Check the weather report
  • Cover the floor with a dust sheet or sheeting
  • Use a good paintbrush for cutting in and filling grooves
  • Use the roller once you have cut-in groves/ handle
  • When using a roller always go up and down
  • Apply two coats to be sure you have applied enough paint

TOP TIP: Before painting oil the garage door mechanism with grease or WD-40.
