Painting a wooden garage door can really bring it back to life. New paint will protect the wood and give it some much-needed colour if the colour has dulled. But how do you paint a wooden garage door, and which paints are the best to use?
Well, today, we’re going through the steps of how to paint a wooden garage door and tell you about the best paints to use.
We also have some tips on how to repair wooden garage doors if you notice any rot as well. Let’s start with how to paint a wooden garage door, shall we?
The first and most crucial step in painting anything is to strip away any old, flaking paint.
If you skip this step, the fresh coat of paint won’t adhere properly. For wooden garage doors, you have several options to remove old paint: chemical strippers, orbital sandpaper, or a heat gun. While sandpaper alone can do the job quicker, it will also require a good selection of quality sandpaper. Using a heat gun can help loosen the paint, making it easier to scrape off and saving you money on sandpaper and expensive sanders.
We highly recommend investing in an electric sander. Combining all these methods will significantly expedite the prep work. Plus, both the sander and heat gun will come in handy for many other DIY projects. If your garage door has decorative features, like the one in our examples, you’ll also need to do some hand sanding.
It’s essential to remove as much of the old paint as you can. If some parts of the old paint are still in good shape, you can leave them be. However, be prepared to give those areas extra care 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.
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.
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.

With prep time, you can paint wooden garage doors in a weekend.

However, most DIYers should be able to paint wooden garage doors in a weekend or a weekend and one evening if the paint you use takes a while to dry.
