Now we’re finally in the midst of summer, it’s time to get on with all the big jobs around your home and garden before the colder weather returns. One such job is repainting your windows. Freshly painted windows can greatly improve the look of your home. But this task has far more importance attached to it than kerb appeal alone. That’s because the paint helps to protect the material underneath it, acting as a physical barrier between your window and the elements.
In the case of aluminium windows, they are a metal which means they are more prone to corrosion. Rainwater and even salt in the air can corrode aluminium windows. However, the good news is that by painting your aluminium windows, you can ensure they not only look their best but are protected from the elements too. Here’s our guide on how to repaint aluminium windows.
The prep work
When it comes to painting any surface, prepping the material beforehand is key. Otherwise, the paint won’t adhere properly and the finish won’t be smooth either. To begin, give everything a good clean. The external side of your windows, in particular, may have dirt and other debris that needs cleaning off. We’ve put together this handy guide on how to clean aluminium windows if you’re unsure. Make sure everything is dry before you proceed.
Sanding is also an important part of the prep process. For this, you’ll need some sandpaper that does not exceed 150 grit. Work the sandpaper in one direction, and be sure to go over any bumps so that the entire surface becomes smooth to work with. Once you’re happy, remove any residue that’s been left behind from the sanding process, so that it’s ready for painting.
Primer
Primer is routinely applied to all paint surfaces. However, in the case of aluminium windows, it’s even more crucial as most paints will not stick to it otherwise. Whatsmore, metal windows are more susceptible to oils, dirt and even fingerprint marks that can ruin the paintwork.
Be sure to follow the manufacturer’s instructions to ensure even coverage. If using a spray primer indoors, you’ll also need to cover wall and floor surfaces too. It’s also possible to use a traditional primer which you can apply using a brush or roller, but you may find a spray quicker and easier to use. Leave the primer to dry overnight, or for a minimum of 8 hours before continuing.
Painting
Not all paint is created equal. In the case of aluminium windows, the paint you choose needs to be compatible with metal. Remember, windows can also be made from uPVC and wood, and each of these surfaces requires a different paint type. For aluminium windows, high-quality acrylic paint works best. Like the primer, you can also buy aluminium-friendly paint in a spray can. However, you may need to remove the windows to ensure even coverage. If this is not possible, it’s best to stick to a traditional application method.
Your windows will require several coats of paint, which are best applied evenly and in thin coats. Keep applying until you cannot see any of the frame anymore. Be sure to cover any hard to reach areas, especially if you have curved arched windows. On that note, leave a small amount of overlap between the glass and the paint. Doing so will ensure the unit’s watertight seal remains intact. Leave the windows overnight to dry before adding any more coats.
Architectural Powder Coating: The Alternative To Painting Your Windows
There is another way to improve the look and longevity of your aluminium windows, and that’s to use architectural powder coating. It works by applying a free-flowing dry powder to your windows, which is then cured under heat. The powder then cools and sets, and the finished result is more durable than conventional paint. Another benefit of architectural powder coating is that any colour or finish can be applied to the window.
For example, if you’ve just had your house rendered white, you can turn your aluminium windows grey. Or, if you have aluminium windows on your business premises, you can paint your aluminium windows in your company colours. There are endless ways you can refresh the look of your aluminium windows with architectural powder coating. It can be applied to all window shapes too!
