How to Paint Aluminium Window Frames

If you have outdated aluminium home windows that you want to either restore the existing color or you desire to adjust the colour, then, you can rest effortless. You’ve occur to the suitable spot.

The process of aluminium window painting can be broken down into a series of steps with two distinct levels. These are preparing and application. The inexperienced nonetheless, will try out and skip on the planning to the detriment of the appear and durability of the finished product.


The sum of planning necessary largely relies upon on the sort and condition of the first substrate. For instance, if you have old powder coated painted aluminium home windows that has chalky paint and rubs off in opposition to your fingers, then this will choose a ton far more preparation than more recent powder coated area which is not chalking and is remaining painted for a color alter.

Even so, anodized aluminium windows will get a lot a lot more preparation than all other substrates regardless of its substrate condition because, the surfaces needs a ton additional mechanical abrasion to crucial the area up plenty of to permit the paint to stick.

Security of adjacent finished surfaces- Whenever you are portray isolated portion, it is vital that you guard adjacent concluded surfaces. When painting the aluminium home windows in your dwelling or condominium, you may will need to believe about placing plastic drop sheets down, adopted by canvas drop sheets. I recommend making use of plastic movie and 3M, which you can with a hand dispenser to protect the glass and the partitions right encompassing the window body.

Cleansing – Make certain all surfaces are cleanse and free of filth. Grime and grease are important in the system of aluminium window portray. If surfaces are dirty then paint adhesion is lowered. Cleanse the frames on the outside the house with soapy water and a sponge. However, use a cleaning soap that is salt free of charge this kind of as truck wash. Clean off all excessive soap with thoroughly clean refreshing water.
Then, alternately clear surfaces down both equally inside of and out with solvent clean such as prepsol.

Use a scour to implement the solvent. The scour will clean up and vital the area at the very same time. It is significant that you have out a second solvent clean on filthy home windows by implementing solvent with a clean fabric then wiping off with an additional thoroughly clean cloth.

Sanding the substrate – There is no simple way all around this system. This can be hard and monotonous specifically receiving into the tighter spots these types of as the upper channel because there is no mechanical sanding equipment that can make the work a large amount a lot quicker. As a result, undertaking the work manually by hand is tricky and time consuming.

If you have powder coated floor that is chalking, I would advise sanding with 120 grit. The sand paper is less possible to clog. If your substrate is powder coated and is not chalking then 240 grit will be sufficient to important the floor particularly if you have scoured it first. On the other hand, if your substrate is anodized then you happen to be in for some serious do the job since you will need to break out the 60 grit sand paper. Have some masking tape band aids for the finishes of your fingers all set since this is the place you are heading to be “rubbing your fingers to the bone.”
Sixty grit will truly carve the anodized surface up. And you would want the paint to genuinely adhere, ideal? Skip this and you can expect to be performing the occupation all more than all over again. The moment you have accomplished this, it can be finest that you go around the work once again with 120 grit sand paper to clean out the gouges prompted by the 60 grit.

You might be virtually all set to get started the fun element which is making use of the paint. Just right before you paint a window give it one more clean up wipe making use of your solvent clean, remember to use two diverse cleanse cloths.

Portray- Use a 3 coat process with the initial coat currently being a primer sealer light coat- use a single pac etch primer. The next coat getting the 1st of the top coats, then the second major coat becoming the third coat.

At this point, you have to make a pair of decisions. First, what form of paint do you want to apply? I advocate both oil based enamel or a two pac poly urethane. If you have little or no working experience with employing two pacs, stick with the oil centered enamels and utilize it working with a top quality brush. Nevertheless, if you have utilized two pacs just before, then, the only way to utilize them is by utilizing an HVLP spray gun in purchase to attain excellent finish. The reward of using a two pac paint in excess of an oil based mostly enamel, is that you will get a extra tough top quality end that closely resembles a powder coat finish.
