How To Paint The Aluminum Window Frame

Here we’ll discuss how you can start painting. Also before you start painting, there are a few things you need to do before. Things like picking a color, preparing the paint itself, priming the frame, and then finally painting it. 

With each of the steps, we are going to discuss everything from which color to buy and how to prepare the paint and everything. 

Step 1 of 4: Picking A Color For The Frame

Picking the right color for your frame is very important. It carries a lot of character to your house. The color of the frame mostly depends on the personality, surroundings, and obviously the type of house you have. 

Some modern-era houses with a compact design look best in brighter colors like white, blue, yellow. On the contrary, the older house suits the darker colors, such as black, brown and others like these. 

But if you want the color of the frame could be something totally different. You could go for something bold like red, maroon, violet, even lime. It doesn’t matter as long as the color compliments your house, and reflects your personality. Apart from these, go nuts with the colors. 

Step 2 of 4: Preparation For The Paint

After you decide on the color that you’ll be painting the frame, you need to start prepping.

Firstly you’ll need to clean and disinfect the whole frame. To do that, you can use soap water, this should clean out the dirt and grease from the frame. To disinfect the frame, you can use any kind of glass cleaner. 

If you have painted the frame or it came colored from the store, you can also remove that. To remove the old paint, you can use a paint removing solution. You just apply a thick layer of the paint remover to the designated area and for the visible reaction. 

Depending on the age and type of the paint, the time could vary. If you don’t see any reaction, try applying again. Once you see the reaction happening, you can start to pry that area, and the paint should come off. 

Step 3 of 4: Priming The Frame

Before we start painting we need to take care of one more thing, which is priming. Any kind of painting is useless without priming. It ensures the longevity of the paint and makes sure it has been applied properly and evenly. 

You need to cover the surrounding of the frame to avoid spoiling them while applying the primer. Ideally use masking tape, as it is not harsh on the paint while ripping off and stops primer from spilling. 

After you’re done securing the parameter, you can start priming. You need to apply the primer evenly until you can’t see the metal underneath. Let the primer dry for about 8 to 12 hours. Be on the lookout if there are any spots that have not been primed.

Step 4 of 4: Painting The Aluminum Frame

And now, after completing every single step, we are finally going to be painting the frame. Note that, painting different parts of the house requires different paint variations. And this is the same for an aluminum frame as well. 

To start things off, you need to open the lid of the paint container. Then, stir the paint for a bit. The paint might be clotted, stirring it frees the clots and evens out the paint. 

For painting the frames, you’ll need a small paintbrush. After you dip the paintbrush in the paint, scrape off the excess paint from it before you apply it to the frame. 

Seamlessly brush the paint onto the frame for a nice even coat of paint. Do this until you have done a single coat on the whole frame. Keep applying the paint until the frame isn’t visible. 

Keep in mind to apply another coat of paint, after the previous one has dried. It’s always better to do multiple coats rather than one thick coat. This way, the paint dries up quickly and the finished paint looks way better. 

After you’re done with the painting, let it dry. It should take about an hour to dry.

Once you’re done with all the coats and the paint has dried, it’s time to open up the masking tapes. You can try peeling it off with your hand, or you can use blades or razors. Be careful using sharp objects, as it could cause self-harm if you’re not careful. 

If you have followed the steps as we have discussed, then congratulations, you just learned about painting aluminum window frames. This is certainly simpler than opening a window without buzzing the alarm.
