Garage Door Paint – What To Buy And How To Use It

Garage door paint can be used to give your garage a fresh new look. Your garage contributes to the overall style of your home so it’s important it looks good. Could your doors use some TLC?

Rust spots or flakey paint can all contribute to an untidy image but using garage door paint is an affordable, quick and easy solution.

You should also make sure you use the right paint for the type of door you have, e.g wood or metal. Using the wrong paint can give you a less than professional finish. Be extra careful if your doors are galvanised steel as you need a particular type of paint for this surface.

Follow our step by step guide for achieving a professional finish you can be proud of.

Step By Step Guide To Painting Your Garage Doors

1. Clean The Garage Doors

You should give your garage doors a good clean before you start painting. Doing this will help reveal any imperfections that need touching up.

Use sugar soap or warm soapy water and an old cloth or rag. You want to remove all dirt and grease. Make sure you get in all the nooks and crannies. Open the door and do all around the edges as well.

Pro Tip: Clean around the door frame so that when you shut the door it doesn’t transfer the dirt to your fresh paintwork

When you’ve finished cleaning, make sure the door is dry before you apply any primer or paint.

2. Remove Or Cover Fittings

To protect your fittings from paint splatters you should remove them or cover them with masking tape. You want to make sure door handles, hinges and brackets stay in good condition and look their best after the paint job.

3. Smooth the Surface

Now that you have a clean and dry surface, inspect it thoroughly and look for any rust, loose paint or any notable drip marks in previous coats of paint.

Take the time now to smooth out these imperfections using coarse sandpaper or a wire brush. Pull any flaking paint off and use the sandpaper to blend any ridges you can feel to ensure a lovely smooth finish.

Wash again using a warm soapy solution to remove any dust from the sanding down, and allow to dry.

4. Prime (Only If Required)

Depending on your garage doors this step can differ.

Check the options below for what you will need to do

  • Many new garage doors come ready primed, so you can just paint these. E.g these glazed side-hung doors from B&Q
  • If any bare metal is exposed use a metal primer
  • Use undercoat if you’re painting over old paint
  • You can get combined primer and undercoat if you have a mix of surfaces to prepare

Place dust sheets or newspaper around the garage doors to catch any drips or paint splatters. Then use a paintbrush to apply the primer or undercoat, as required, to your garage doors.

Pro Tip: Use special galvanised metal paint if you’re painting galvanised metal, otherwise the paint will peel off. Find out more about painting galvanised steel here.

5. Clean Again

Yes again! Cleaning in-between steps is a good tip to get the best finish possible. Allow the primer to dry completely, then wipe down again with a damp cloth and allow to dry before painting.

6. Apply Finish Paint

Normally when painting wood you should go with the grain. However, if there are any fine splits in your doors, paint across the grain to cover the split, then go over it again, following the grain. The paint will act as a filler and give you a smooth finish.

You should paint in layers, rather than trying to put paint on too thick. You’re likely to need at least two layers. Allow the first layer to dry completely before adding the next one.

You should inspect the paint’s finish when it’s dry to assess if another coat is required.

Pro Tip: Paint when the temperature is between 8C and 25C to get the best finish on your garage doors.

7. Remove Protective Materials And Add Any Fixtures Back On

Carefully remove the dust sheets and masking tape. Only do this when the paint is completely dry. Otherwise, it can pull at your new paintwork or disperse dust which can stick to the surface.

Refit any handles, hinges or brackets that you removed at the beginning. If you need to replace the hinges, read this article to find out which hinges you might need.

8. Clean Your Brushes

Look after your brushes by giving them a good clean in a solvent such as white spirit or turpentine (known as “turps”).
