How to paint a wooden garage door

1. Remove old paint from the garage door

The first, and most important step, in painting anything is to remove any old, flaking paint. If you don’t, the new coat paint won’t stick to the surface properly. You can remove old paint from a wooden garage door with chemical strippers, sandpaper or a heat gun. You can just use sandpaper, but it will take longer. You can also use a heat gun. This will loosen the paint from the surface. And then you can use a paint scraper to remove it.

We would recommend investing in an electric sander for this. And using a combination of all the methods to remove the paint. It will really speed up the prep process, and you’ll use the sander and heat gun in loads of other DIY projects too. You’ll need to do some hand sanding here as well if your garage door has any decorative features like the one shown in our examples.

Ensure that you remove as much of the old paint as possible. If the old paint is in a good condition, you can leave it, but those areas may require extra attention later in the process.

Now that you’ve removed as much of the old paint as you can, you can take a look at the garage door and see if you need to make any repairs. Check common problem areas like the bottom of the door and any areas where the paint has been missing for a while.

If there are minor rotten areas, you can use a two-part resin bonding agent or wood filler to fill these areas and then sand it back flush with the door. If there are entire panels or boards that are rotting, you will need to replace them, for this task you can use tricoya wood. If your DIY skills aren’t up for this challenge, a local joiner or hobbyist woodworker may be able to help with this step.

3. Prepare the garage door for paint

Now that the paint has been removed and all of the rotting sections have been sorted out, it is time to prepare the garage door for paint. First, remove as much dust as you can. White spirit is great for this, but make sure you dispose white spirit correctly if you have any leftovers.

Add a few drops to a rag or paper towel and wipe the doors down as thoroughly as you can. Next, mask off any areas that you don’t want to paint. In the case of our example garage door, that would be the brickwork of the garage, the windows and the lock.

Now you are ready to paint.

4. Paint the garage door

You want to start with a good quality primer that is designed for outdoor use. You may need to sand between coats of primer, but check the instructions on the can that you buy as they are slightly different.

Most primers will require light sand before the topcoat is applied, though. You can then add the paint of your choice to the garage door. Do this in thin coats and add two-three coats depending on the paint you use.

You can use a brush and roller to apply primer and paint, or you can spray both if you have a spray gun. Ff you do not have paint sprayer, check our blog post where we described different paint sprayers available on the market to help our readers pick the right paint sprayer for their job.
