Aluminium window frames have become quite popular due to their durability and ease of maintenance. One of the things aluminium window frames do need on occasion, however, is a new coat of paint. And you cannot just paint over the old layer of paint, you have to do a number of other things first.

First you need to clean your aluminium window frames. It is best to use a solvent to remove the paint and get all of the dirt off properly. Make sure you use a scourer to wash the paint off. This will help make the surface a little rougher so that the paint has something to stick too. You should then sand the surface of the aluminium window frames. It is best done by hand, particularly if there are some hard to get to corners. Aim to get as much of the old paint or powder coating off as you can, it will make the new coat last longer and look better. Once you have finished sanding, you have to wipe the aluminium window frames down again to get rid of all the dust you raised while sanding.

Then you need to cover all the surfaces you do not want painted. You can use old newspaper and masking tape or plastic, it is all up to you.

You then need your paint. It is best to do three coats, one primer coat and two colour coats. If you have access to a paint gun, then it is best to use a two pac poly urethane paint, if not then use an oil based enamel and a high quality brush.

You can really give your aluminium window frames a professional looking finish if you can be bothered to take the time to paint them properly. It is important to do it right the first time, else you will end up with dreadful looking window frames and will have to start from scratch in a few short weeks because all the paint has started to lift due to a lack of sufficient preparation. So, when it comes to painting your aluminium window frames, make sure you do it right the first time.
