Primer Paint

It is essential to paint aluminum because it is a very smooth material, so adherence is always a problem. It is a solvent-based primer to ensure more outstanding durability. We have also chosen it in the spray version because it is much easier and faster to paint. The finish achieved is magnificent: uniform, smooth, and without brushstrokes or anything.

Enamel. It is the final finishing paint. It gives a last look: the chosen hue and shine depend on the enamel. We have also used a solvent-based version, for the same reason as in the primer’s case: the more outstanding durability. We have also chosen it in a spray version for the same reason as before. The finish will be perfect, even looking like a factory lacquer at some points.

How to Paint Aluminum Window Frame

Step-1:

Takedown the windows. As we spray paint, the best way not to paint the window’s surroundings is to unhook it. It is effortless: sliding windows are usually lower by pushing them upwards until they remove from the rail where they supporters.

Step-2:

Remove the windows. It can be painted without disassembling, adequately protecting the crystals. But the finish is much better if we disassemble them. With this, we make sure to paint all the points homogeneously and that no unpainted or painted lines are seen here and not here. 

Also, with this, we make sure that all the following steps are executed in the best way and more straightforward, for example, cleaning, which will be more comfortable by cleaning small profiles than the entire window; or the spread of paint, which is better in short pieces than in a whole sheet, etc. 

The leaves are disassembled, leaving the profiles that make up the leaf. Each sheet has four profiles, forming the frame that surrounds the glass. In our window, the profiles are screwed together, so we only have to unscrew them.

Step-3:

We remove the supporting impellers from below and the anti-dust gaskets from the profiles. These elements are embedded in the profiles. To avoid painting and damaging them, it is best to remove these small pieces and then reassemble them. It is straightforward.

Step-4:

Protect the walls and the floor in the painting area of ​​the profiles. This is very, very important. 

Wasting a little time here will save you a lot, later on, removing any paint stains and drips. We will use cardboard fixed to the floor and wall in the area to apply the spray. We use masking tape to improve the edges of the cardboard.

Step-5:

Protect the outline of the window frame. For this, we use transparent plastic wrap, and we will help ourselves in some specific points of the masking tape under challenging encounters and areas. 

It is also beneficial to use painter’s blankets to protect the hole so that paint does not come out. We will also need cardboard of a manageable size, which we will use as protection just in the area behind where we are painting with the spray.

Step-6:

Cleaning of profiles. We must thoroughly clean the profiles to avoid dust, dirt, or grease. These elements are the enemies of the adherence of our paint. We must remove them to achieve perfect commitment. Then we will have to dry them.

Step-7:

Profiles primer. We now start painting. For this, we place them in the protected area mentioned before.

The good idea is to put them vertically, resting lightly on the wall. Then apply the primer, which we have chosen, is a synthetic spray. 

You must use it accurately, so we dedicate a later section to the proper spray painting technique. Let the repainting time wait, in our case, 2 hours to paint with synthetic enamel (with solvent).

Step-8:

Painted with synthetic enamel. After 2 hours, we apply the first coat of synthetic enamel. We have chosen spray because it is much easier and faster, and also, the finish is much better if we use the technique correctly. In our case, with a 2nd hand, we get the perfect finish we are looking for. We must wait for about 30 minutes to apply this second coat and disassembled 1-leaf profiles of a window. We just gave him the enameled hand.

Step-9:

Priming and painting of the window frames. After painting the profiles and dry, we can start to prime and then paint the window frame. The procedure is similar to that of painting the profiles. It only differs in that we must be careful not to paint the neighbor! To do this, we must close the hole in the window or use small cardboard as a screen.

Step-10:

Finally, we must mount the windows again and place them back on their rails. When mounting the windows, the placement of the rubber gaskets is essential. We must always put them in the correct position, with the joints’ tips pressing against the glass, to fix it properly to the aluminium frame.

Step 2: Remove Stains

Any stains on the metal, mostly rust, can interfere with the finished paint color; therefore, they should be removed before proceeding. Oil-free steel wool and water-based detergent should be just what you need for any stain. Rust can be removed with various household items, such as vinegar or baking soda if appropriately used. An old toothbrush can help remove rust from any hard-to-reach spots. Once the aluminum is transparent, rinse it with clean water and dry it with a clean cloth.

Step 4: Print the window frame

The metal must be prepared for the paint to adhere correctly. Use a metal primer according to the manufacturer’s instructions, which should be somewhere on the can, and allow the primer to dry before proceeding to the next step.

Step 5 – Paint the topcoat

Open the paint and stir for about a minute to match the color. Dip a small paintbrush in it and scrape any excess off the side of the bucket. Gently drag the brush up and down the window frame to get an even layer of paint. Reapply multiple coats of paint until the aluminum is fully colored, with no metal shining through. Ensure that paint dries up before cleaning your frame.

Step-1: Consider the current weather

It seems like a joke, right? Well, it isn’t. You must bear in mind that you must look at the weather conditions in your area if you want to paint your windows. And because? Well, because when you finish painting the window frames, you must leave it open to dry completely.

It happens that, as we mentioned in another note, the weather can play a trick on us when it comes to painting. Taking into account that rain, for example, can spoil our progress and we have to repaint the frames, as it is the place that is most exposed to this type of problem. Therefore, it is advisable to paint during the day and with natural light to have better visibility of our work.

Step-2: Choose the paint you want

It would help if you considered what environment it is. If it is an area with high humidity, such as the bathroom, you could consider a gloss paint (since gloss paints tend to have more resistance than matte color, and they are also easily cleaned).

Painting a window frame is a necessary investment that is worth it if we want to give our home a better atmosphere, as doing so will change the aesthetics of the room and generate a visual impact with great style.

Choosing the perfect color to paint the window frames allows us to play with the different color ranges, we may want to use a more risky color, but a complete wall may seem too much; in this way, we can satisfy our wishes by choosing that color for the frame from a window, without having to recharge a room with it.

On the other hand, do you have a wooden frame? It is then necessary that you remove the old paint. To achieve this, we suggest you use a chemical stripper. After stripping the surface, you should sand the area with medium-grit sandpaper, taking the opportunity to smooth the body to your liking if you find many imperfections. If you find holes, you could use a select wood paste to cover the cracks (remember to sand later to smooth everything out).

Step-3: Select the appropriate brush

Pick the right brush and take a good look at the surface you are going to paint.

Make sure that the brush or roller to be used is of outstanding quality. The final product depends mainly on a useful tool.

We recommend starting with the horizontal part of the frame, both the bottom and the top, and then continue with the rest when you have achieved the desired color.

Meanwhile, if you have an aluminum frame, we also have techniques to paint such edges. We know that it may seem very difficult, but it is not impossible. 

To start, sand the aluminum surface very well so that the paint you will apply later can adhere properly. Then wipe with 96-degree alcohol dampened cloth to remove impurities and dust.

When you have the surface ready, go on to paint the first coat with a short-nap roller. This will allow the surface to better grip the paint and last over time. Let dry for at least 6 hours.

After that time, apply a layer of polyurethane enamel. This product is very durable and, although it has a more pungent smell than other materials used, it will help you a lot.

Step-4: Use the duct tape

It is a crucial material. Tape the edges so that, when you start painting, the paint does not exceed them, and you have a very professional job.

Also, take great care not to paint the glass because it is a massive problem in most cases since it is complicated to remove.

Step-5: Remember: in paint, two are better than one

Always paint the same surface twice, thus applying two coats of paint. Therefore, you will be able to cover the entire area professionally. If we are looking, for example, to break the monotony of the purest white, we can take a risk with a black window frame, achieving a more significant impact than with any other color.

Black also fits in warm environments with natural textures and tones such as white, natural wood. It is prevalent to incorporate it into classrooms.
