Whether you want to update the look of your home or give your tired garage door a freshen up, painting it can be a good option if the internal mechanism is still working well and the door itself is not damaged. Coloured garage doors can look brilliant when done properly and can really enhance the look of your home, making it a nicer place to live and boosting your kerb appeal. You may even find that the value of your home goes up, especially if your garage door used to look tired, faded or had flaking original paintwork. Of course, painting your garage door is a little more complicated than just buying some paint from your local DIY store and slapping it on – depending on the material your door is made from, you’ll need to follow a few guidelines to get the best from your door.
For the purposes of this article, we’re going to stick with the most common type of garage door, which are ones made from steel. Our steel up & over (available in both canopy & tracked opening mechanisms) garage doors are representative of the majority of garage doors used by residential properties in the UK, so even if you haven’t bought your steel door from us, you can still use the information provided in this article.
Steel garage doors are most commonly made from galvanised steel, although very old doors may not have this protection. Galvanising steel involves it being dipped into a bath of molten zinc, which coats the steel and prevents rusting. If you were to apply paint straight onto the galvanised steel itself, then you would find it peeling off in large sections after just a few days.
To prepare your garage door for painting, you must first give it a wipe down with warm soapy water to remove any grime and debris. Sand down the door as best you can to remove any peeling or bubbling paint from the surface and to get rid of imperfections. Once you’ve done this, cleaning the door with a substance called ‘sugar soap’ (which is available from most DIY stores) will remove any grease or remaining dirt.
Now it’s time to apply an undercoat. Before you do this, check that the door has not been rubbed right back to the bare metal. Any places where this has occurred will need to be primed before an undercoat is applied, but fret not – this isn’t as labour intensive as it seems. Most paint suppliers will stock a primer/undercoat blend which means you’ll just have the one coat to worry about. It’s cheaper this way too!
When it comes to painting your garage door, you’ll want to get an exterior gloss or metal paint in the colour of your choosing. Your local DIY store will be able to help you pick the best type of paint for the job. Remember before you begin that darker colours will soak up the heat from the sun and may fade much quicker than lighter coloured paint if situated in a south-facing position.
When it comes to painting your door, there’s an order that you should do it in to prevent drips and ensure a smooth, even finish. First, you should paint the very top edge, and then work around in a clockwise or anti-clockwise direction to complete the remaining three edges. Once this is done, paint the top third of the door, then the middle third, then the bottom. You should not need to paint the inside of the door. Going over the paint with a dry brush once it’s been applied will even out the finish and ensure it’s nice and smooth.
Once you’ve painted your door going by the instructions above, you should have a great-looking asset which will hopefully last you many more years to come. Many homeowners wonder how often they need to paint their steel garage door, and the answer is simple – when you feel it needs it. Modern galvanised steel coloured garage doors are constructed in such a way that they should never need repainting. The powder coat finish given to these doors is designed to be strong and weatherproof, so it won’t fade or peel.
