How to Paint Alloy Window Frames

If you've old RDA aluminium windows that you want to either restore the existing colour or you need to change the colour, then, you can rest easy. You've come to the proper place.

The process of aluminium window painting may be divided in to a number of measures with two distinct stages. These are preparation and application. The inexperienced however, will try and skip on the planning to the detriment of the look and durability of the finished product.


The total amount of preparation needed primarily depends upon the kind and condition of the first substrate. For example, in case you have old powder coated painted aluminium win-dows that's chalky color and rubs off against your fingers, then this can take a lot more preparation than newer powder coated surface that's perhaps not chalking and is being painted for a colour change.

However, anodized alloy windows will take a lot more preparation than all other substrates irrespective of its substrate situation because, the surfaces needs a lot more mechanical abrasion to key the surface up enough to permit the paint to stay.

Defense of adjacent finished surfaces- Whenever you are painting remote section, it's essential that you protect adjacent finished materials. When painting the alloy windows in your house or apartment, you will need to consider putting plastic drop sheets down, followed closely by canvas drop sheets. I would suggest using plastic film and 3M, that you can with a hand dispenser to protect the walls and the glass directly surrounding the window frame.

Cleaning - Make sure all surfaces are clean and free from dirt. Oil and dirt are important in the process of aluminium window painting. If areas are filthy then paint adhesion is paid down. Clean the frames on the outside with a sponge and soapy water. However, use a soap that is salt free including truck wash. Clean off all excess soap with clean fresh water. Then, instead clean surfaces down both inside and out with solvent wash such as prepsol.

Make use of a check to apply the solvent. The trawl will clear and key the top at the sam-e time. It's essential that you perform an additional solvent wash on windows through the use of solvent with a cloth then wiping off with another clean cloth.

Sanding the substrate - There's no simple way around this process. This can be difficult and tedious particularly getting into the places including the top station because there is no mechanical sanding equipment that can make the work much faster. Thus, performing manually yourself is hard and time intensive.

I'd recommend sanding with 120 grit, for those who have powder coated surface that's chalking. The sand paper is less inclined to clog. If your substrate is powder-coated and is not chalking then 240 grit will undoubtedly be enough to key the surface particularly if you have scoured it first. However, if your substrate is anodized then you have been in for some real work because you'll have to use the 60 grit sand paper. Possess some masking tape band aids for the ends of one's fingers ready because this is where you're going to be "rubbing your fingers to the bone."

Sixty resolution can really carve the anodized surface up. And you'd want the color to actually stick, right? Skip this and you'll be doing the job once again. When you have done this, it is most useful that you go over the work again with 120 grit sand paper to erase the gouges brought on by the 60 grit.

You are nearly willing to begin the fun part which is using the paint. Prior to you paint a screen give it yet another clean wash using your solvent wash, make sure to use two different clean towels.

Painting- Use a three coat program with the first coat being fully a primer sealer light coat- use a single pac etch primer. The second coat being the first of the top coats, then the second top coat being the third coat.

Now, you've to create a few choices. First, what sort of paint do you want to use? I suggest either oil-based enamel or a two pac poly urethane. If you have minimum experience with using two pacs, remain with the oil based enamels and apply it using a quality brush. However, when you yourself have employed two pacs before, then, the only way to utilize them is to use an HVLP spray gun in order to gain quality finish. The main benefit of using a two pac paint over an oil-based enamel, is that you'll get a more durable quality finish that closely resembles a powder coat finish.
