Repairing Scratched Aluminium

As we have mentioned above, aluminium window frames are affordable, durable, and low-maintenance window frame options, especially compared to timber, as aluminium is cheaper as well.

However, they can pick up scratches like any other window frame material does. This is why we have provided ways to fix this problem below.


If you have a plain aluminium window frame that does not feature a special surface or texture, then sandpaper might be able to solve your problem.

You should take care, though, and be sure to use the finest sandpaper that you have so that you don’t damage your window frame further.

If there is only one small scratch bothering you, then you should not use a sander. You can use a piece of sandpaper and some elbow grease until all of the scratches are gone.

If your window has many scratches, then you can use a sander, but you should be careful not to create more damage.

Touching up

If your window frame comes with either a smooth glossy finish or a matte finish, you might be able to use some touch-up paint to hide scratches.

You can often use some acrylic paint to do some touch-ups on matte finishes if you can find it in a colour that matches your window frame.

If your frame has more of a glossy look, then automotive paint will be a better option, as long as it matches the colour of your frame.

You should use this paint sparingly when applying, as you could make the rest of your frame look out of place. Alternatively, you could repaint your window frames entirely if you think they look a little old.

Deep scratches

If your aluminium window frame has deep scratches in it that have damaged more than just the surface of your window, then you may need to opt for a different solution.

These scratches can create holes or gaps in the frame that rainwater can get through, so you will have to know how to stop water leaking through an aluminium window.

You can repair these scratches using some composite or wood filler. Once you have placed your filled on the scratches and it has dried, it can be sanded and painted to look like the rest of your frame.


How do you clean aluminium?

If you want to clean your aluminium window frames, you can do this using some dish soap or vinegar solution and a cloth to clean them. If a lot of dirt and debris have built up, then you can use some WD-40 or something similar.

If you are trying to clean mould off an aluminium frame, use a soft cloth or sponge to avoid damaging the aluminium any further.

Can you repaint aluminium window frames?

Yes, you can easily repaint an aluminium window frame. If you think there are too many scratches on your frames, then you can cover the glass using some newspaper and sticky tape.

You can then spray them, remove the newspaper and tape, and leave them to dry.

Which coating is the best for aluminium windows?

A powder coating can increase the durability of your window frames significantly. A powder coating can make your frames more resistant to corrosion, fading, and even scratches.

Powder coating can also be painted over if the layer of paint has been damaged or scratched, so you can get them looking as good as new again!
