Aluminum objects are very common in everyday life. But over time, they lose their appearance, and you may need to renovate and paint them. Most people who want to paint this metal believe that it is quite simple and easy to do. But it is not enough to put the brush in a jar of paint, smear it on the metal and wait for it to dry. Actually, everything is much more complicated than it seems. The process of metal painting requires not only skills and abilities but also knowledge about the composition and types of paints and the properties of the aluminum surface.

Painting aluminum can become a real challenge, especially if you are going to do it at home. The difficulty of working with such a material is due to its oxidation upon contact with air. Aluminum has excellent corrosion resistance as it forms a special film when interacting with air. It prevents moisture and rust. At the same time, this layer prevents the penetration of paint into the metal. Therefore, it is extremely important to follow the instructions for painting aluminum surfaces, otherwise, your efforts will be practically useless, and the color will not last long.

Buyer’s Guide

If you are going to paint aluminum at home, be prepared to devote enough effort and time to this job. If you do not do it correctly, the wrongly applied paint will be easily scratched or damaged. Moreover, it can simply come off after drying. First of all, learn everything about the technology you will need to follow for a good result. This way you will achieve strong adhesion and the painted surface will serve for a long time.

Aluminum is a metal with high chemical activity. The aluminum surfaces get quickly covered with a special oxide film when they are in the open air. That is why, the paint plays not only a decorative role, but also protects this metal. In general, you can use two methods for this job – you can plain aluminum with anodizing or apply a special primer to avoid this procedure. Let us have a look at these methods in detail.

How to anodize aluminum?

Now there are many ways to paint aluminum on your own, but a durable effect can be obtained with the help of special pretreatment of the surface. It is anodizing that allows you to avoid a temporary result. What is the purpose of this procedure? This process improves the appearance of a metal and does not allow it to react to the air influence. Anodizing makes the metal surface look greyish. But you can use any suitable paint to give the surface a different color.

  • You will need baking soda and usual table salt. Then you have to make two highly-concentrated solutions. For this, dissolve substances separately in water and leave for thirty minutes. You may occasionally stir them, and these should be filtered finally.
  • When you mix these two solutions, you will get the electrolyte. For the best results, take 9 parts of the soda concentrate and 1 part of the salt solution. Be sure to mix everything properly.
  • An aluminum surface must be prepared for the procedure. Use sandpaper to process it, degrease it using a special substance or prepare a solution of washing liquid with hot water. Be careful not to leave fingerprints on the finished surface. The best method is to use gloves.
  • Then you need to pour the electrolyte into a container and place an aluminum product there. The next step is to find a current source. You can use a device with a voltage of 12 volts and a current of 2 amperes. Connect the minus to the container, and the plus to the aluminum surface. You will need an hour and a half for this process. In the result the surface will get a greyish shade.
  • After successful completion of the process, you can paint aluminum parts.

Using primer for aluminum painting

The above-described procedure can be avoided. If necessary, you can achieve good results without anodizing and use a primer that allows you to increase the quality of adhesion of paint and metal. You will need the following things for this task:

  • kerosene, acetone and cleansers for degreasing;
  • paints that can be used for metal;
  • special primer;
  • sandpaper;
  • a tool for applying paint.

The whole procedure starts with surface cleaning with sandpaper to achieve better adhesion of the primer. The best option is a medium abrasive sandpaper. After this stage, use acetone – apply it with a cloth. It is important to do all this in protective gloves to protect your hands.

The next step is to apply the primer. The key point is to spread the primer evenly as quickly as possible. The result of the treatment largely depends on the speed of your performance. It is suggested to prepare the primer at the very beginning. But small drawbacks that may be found after application of the primer can be improved with sandpaper.

You will need to apply at least two layers to the surface. Before applying the next coating, the previous layer should be ideally dry.

Types of paints for aluminum

Most often aluminum surfaces are treated with the following paints:

  • Acrylic paints. This option is very durable and does not react to moisture and sudden changes in temperature. But you will need a primer layer before using acrylic paint.
  • Epoxy paint. It is made on the basis of special resins, thanks to which it is very strong.
  • Aniline paint. This coating was originally created for textile production. It is optimal for aluminum products that have been preliminary anodized. But it can be low-resistant to moisture and sunlight.

Precautionary measures

After you have chosen the painting method, you should also learn safety measures to follow during this work. It only seems that this process is not complicated. Follow these instructions if you want to paint aluminum at home:

  • It is necessary to prepare the area where you will be conducting the painting. It is advisable to clean it of dust, since its particles can spoil the result, settling on the painted surface.
  • It is important to paint the part in good lighting. So all the flaws, irregularities and smudges will be visible.
  • All the painting procedures should be carried out in well-ventilated areas, regardless of the composition of the paints.
  • It is necessary to avoid drafts.

When working with paints containing toxic components, all work must be carried out in special protective clothing. Protective glasses will also help protect your eyes from splashing components and ready-made formulations. Hands must be protected with gloves.
