To the lovers of chemistry, you are going to enjoy this topic. I never liked the chemical formulae; honestly speaking, it made the better part of the chemistry lessons. Whether you liked your chemistry classes or not, you ideally have basic knowledge about the terms used in chemistry, such as anodization. Leaving that aside, let’s jump right into our discussion. Won’t we?
You can apply Anodized Aluminum in the window and door flames, various finishes, and interior applications like illuminating fittings; This makes it a splendid substance. With that in mind, occasionally, you might want to alter its color to give it a look you wish to, which is why you may ask yourself whether you can paint. So, can anodized aluminum be painted? Read on for more insight.
Like any material, you can paint anodized aluminum. The only takeaway is ensuring the surface is cleaned correctly and allowed to dry before applying a suitable primer and polish. Note that you may need to apply more than one coat of paint to achieve desired results.
Anodized aluminum is a coating that strengthens the aluminum metal and elongates its life. From Lorin.com, anodized aluminum is made through an electrochemical process; The metal is immersed in specific tanks, and an anodic layer is formed in one of the tanks.
Are There Any Benefits Of Anodized Aluminum?
It is not susceptible to corrosion, peeling, and cracking.
Regular aluminum is less resistant to the effects of pollution if left in areas with high moisture content. On the other hand, anodized aluminum can withstand the effects of corrosion and other factors that speed the process of wear and tear.
Easy to paint.
Unlike standard aluminum, you can easily polish anodized aluminum with a paint of your choice.
Excellent adhesive properties.
A highly sticky paint is a big plus to the painter; Anodized aluminum bonds with paint accordingly to give you a stunning finish.
If you are looking for long-lasting material, then anodized aluminum is your best shot. Anodized aluminum is highly resistant to corrosion and other agents of wear and tear, which is why it is stable and durable.
With its outstanding properties and benefits, Anodized aluminum is a good pick for various items and structures. Its durability is unmatched, and its ability to resist corrosive activities is a big plus for all types of uses.
Is it Possible to Paint Over Aluminum?
Put, yes. You can paint Anodized aluminum; Anodized aluminum has superior adhesive properties that allow for faster bonding between the paint and the surface, which is why it is one of the best materials you can paint over with much ease.
Nevertheless, painting over anodized aluminum requires you to follow specific steps to achieve your desired finish. So, which steps should you follow when painting over anodized aluminum? Continue reading to find out more.
4 Steps to Paint Anodized Aluminum
Recall that any form of painting requires you to have all the necessary products and rules to follow carefully. In the case of painting anodized aluminum with the correct items and a few hours, you are good to start your painting. These are the materials you will need:
- Soap, brush, and water
Clean the Anodized Aluminum.
Although anodized aluminum has good adhesive properties, you will need to wash it accordingly before painting it to improve its adhesive properties, which might deteriorate over time due to impurities on the surface. Note that pollutants make it a little more difficult to paint over anodized aluminum.
Scrub the surface with suitable soap and water to remove any contaminants on the surface of anodized aluminum. Use your paintbrush to remove any foreign substances, and then use more soap and water to remove any unwanted substances on the surface. On that note, ensure you rinse the surface with water to remove any soap that might interfere with your anodized aluminum’s adhesive properties.
Have your etching primer ready to apply on the surface immediately; Ensure that the washed material is dry because you don’t want to leave the anodized aluminum surface to catch any impurities from the environment.
Application of the Etching Primer
Place the primer into your container; Work on the material thoroughly and ensure the primer covers every spot because the primer contributes significantly to adhesion between the paint and anodized aluminum. Allow the adequate primer time to dry appropriately, say two hours. In the meantime, ensure you clean your brush adequately because you will need it during the painting step.
Sanding The Surface
You might not achieve a perfect finish when applying the primer, which is why you will need to sand the surface to remove bumps and make the surface as smooth as possible. Sanding will enable you to achieve a clean and smooth finish. However, while doing the sanding, ensure you don’t scrape off the primer from the anodized aluminum.
Apply a thick layer of oil-based paint to your anodized aluminum material. Using oil-based paint will improve adhesion between the color and the surface. A proper bonding between the two substances will allow you to paint the anodized aluminum surface with much ease.
Let the paint dry for about two hours before adding another layer of polish if necessary. To achieve the density of the color you want, you may need to add more than one coat. Note that you must wash your paintbrush before applying subsequent layers.
Anodized aluminum is an electrochemical process which is why it is a top choice among painters. Anodized aluminum has a wide range of applications due to its excellent properties, including window and door frames, finishes, interior applications, and illuminating fittings. Anodized aluminum has superior adhesive properties that allow for easy application of paint. Painting over anodized aluminum requires you to follow specific steps to achieve your desired finish.
