How to Paint Aluminium Window Frames


If you have previous aluminium windows that you want to possibly restore the existing colour or you desire to improve the colour, then, you can rest easy. You’ve come to the appropriate put.

The procedure of aluminium window painting can be broken down into a collection of methods with two unique stages. These are preparing and software. The inexperienced having said that, will consider and skip on the preparation to the detriment of the seem and sturdiness of the completed item.


The amount of preparing necessary largely relies upon on the sort and situation of the authentic substrate. For example, if you have previous powder coated painted aluminium windows that has chalky paint and rubs off towards your fingers, then this will just take a whole lot extra preparing than more recent powder coated surface that is not chalking and is staying painted for a colour change.

On the other hand, anodized aluminium windows will get a great deal much more preparing than all other substrates regardless of its substrate condition since, the surfaces desires a great deal far more mechanical abrasion to key the surface up more than enough to permit the paint to adhere.

Protection of adjacent concluded surfaces- Any time you are painting isolated area, it is crucial that you protect adjacent concluded surfaces. When painting the aluminium home windows in your residence or apartment, you may will need to feel about placing plastic drop sheets down, followed by canvas drop sheets. I suggest applying plastic film and 3M, which you can with a hand dispenser to defend the glass and the walls specifically surrounding the window body.

Cleaning – Make certain all surfaces are cleanse and absolutely free of grime. Grime and grease are important in the method of aluminium window portray. If surfaces are dirty then paint adhesion is reduced. Cleanse the frames on the outside with soapy h2o and a sponge. Nonetheless, use a cleaning soap that is salt absolutely free this kind of as truck clean. Wash off all excessive cleaning soap with clean up fresh new drinking water.
Then, alternately clean up surfaces down both of those inside and out with solvent wash this sort of as prepsol.

Use a scour to use the solvent. The scour will cleanse and vital the surface at the very same time. It is crucial that you have out a next solvent clean on soiled home windows by making use of solvent with a clear fabric then wiping off with a different cleanse fabric.

Sanding the substrate – There is no straightforward way all-around this system. This can be tough and monotonous primarily acquiring into the tighter spots these types of as the higher channel mainly because there is no mechanical sanding products that can make the job a great deal more rapidly. As a result, doing the task manually by hand is tough and time consuming.

If you have powder coated surface that is chalking, I would suggest sanding with 120 grit. The sand paper is considerably less possible to clog. If your substrate is powder coated and is not chalking then 240 grit will be sufficient to essential the surface in particular if you have scoured it to start with. Nonetheless, if your substrate is anodized then you might be in for some authentic perform because you can need to split out the 60 grit sand paper. Have some masking tape band aids for the ends of your fingers completely ready for the reason that this is in which you are heading to be “rubbing your fingers to the bone.”
Sixty grit will genuinely carve the anodized surface up. And you would want the paint to seriously stick, proper? Skip this and you can expect to be undertaking the job all more than yet again. Once you’ve done this, it’s finest that you go in excess of the work once more with 120 grit sand paper to smooth out the gouges prompted by the 60 grit.

You happen to be just about all set to commence the fun component which is implementing the paint. Just in advance of you paint a window give it a further thoroughly clean wipe employing your solvent wash, recall to use two diverse clean cloths.

Painting- Use a three coat process with the initial coat remaining a primer sealer gentle coat- use a solitary pac etch primer. The second coat currently being the very first of the leading coats, then the second major coat remaining the third coat.

At this level, you have to make a pair of alternatives. First, what type of paint do you want to apply? I propose possibly oil based mostly enamel or a two pac poly urethane. If you have small or no working experience with utilizing two pacs, stick with the oil dependent enamels and implement it using a high quality brush. Even so, if you have made use of two pacs just before, then, the only way to utilize them is by working with an HVLP spray gun in buy to acquire good quality finish. The reward of applying a two pac paint over an oil based enamel, is that you will get a much more strong high-quality finish that carefully resembles a powder coat finish.
