Applying paint to metal requires a certain level of expertise. The fact of painting any type of wooden furniture can be complicated if you do not have the practice and the knowledge of what would be the best technique, now, painting metal is almost three times more complicated.
In this blog, we will talk about which paint is better for painting metals as well as the recommended techniques for its application.
To choose the type of paint to be used, the surface to be painted must be taken into consideration; as well as observe the state of the metal. And while it really requires less attention than wood, you still have to be careful.
Types of paint for metal
Regarding the type of paint, latex or acrylic paint is usually the best suited to metal. However, before starting the project, a base (or primer) must be applied, this in order to cover the pores in the metal surface, so that the end result is more uniform.
Clogging the pores of the metal surface will also prevent rust from forming in the future. For this, it is necessary to verify that both the paint to cover pores worked well together with the final paint.
Many people use spray paint as an alternative, but this is recommended to a lesser extent because with the effects of time it tends to fall off and it will surely force you to repeat the entire painting process.
To avoid this type of situation, it is preferable to spend a little more, with acrylic or latex paints, which could translate into better protection for your metal part and greater durability in the finish of your project. Be careful, and paint slowly and evenly to avoid more layers than necessary.
How to paint metal?
The method that most people use traditional and, in addition, is the most infallible to apply is the brush, although if you have airless equipment the finish will be even finer, however, it requires some skill to apply the paint with this machine.
The previous preparation is essential, you must clean the surface to be painted of any contaminating agent such as dirt, remains of previous paint, remove grease, dust, and rust, since if this cleaning is not carried out it could affect the final finish of your project. Try sanding first, and then wipe with a damp cloth.
Metal oxides: The paint for metal is affected if there are no oxide adheres and naturally interferes with the original color. If the cleaning is not done previously the paint will not be able to adhere to the metal and the work will be really bad.
The coat of paint to cover pores is a good option because it protects your metal part longer, and prevents rust from forming in the future. Applying thin layers slowly and smoothly allows the finish to be finer compared to thick layers of paint that, in addition to giving it a bad appearance, the paint will eventually fall off the metal.
