Paint plastic with acrylic
Obtaining any color, whether metallic or solid, modifying the surface appearance, gloss or texture of the part, improving its resistance to abrasion or scratching, hiding molding defects, increasing its resistance to solvents or other aggressive chemicals, improving its weathering behavior and avoiding the exudation of plasticizers are some of the reasons that make it necessary to paint plastics. However, in many cases, purely decorative and aesthetic reasons prevail.
Painting offers effects and finishes that cannot be achieved in any other way, with characteristics that complement and surpass those of unpainted plastic. However, if the painting system chosen is not the right one, the results can be totally opposite to the original purpose. In order to make the right choice, the characteristics of the plastic to be painted and the requirements of the different painting processes must be known.
One of the characteristics that must be known is the temperature that the plastic material to be painted can withstand, since this will allow us to know at what temperature we have to dry the paint, or any other treatment that we have to carry out with thermal resources, without causing deformations in the material.

A paint for plastic has the same purpose as any other paint: to allow the re-establishment of the coating layers necessary to carry out a repair with quality and durability guarantees.
Adhesion promoters or primers for plastics are available in spray or aerosol format. The application of these products is essential to promote adhesion and reduce or eliminate the risk of products applied to bare plastic peeling off over time.
Before applying this type of paint for plastic, the surface must be sanded with the appropriate grain for each stage of the repair and then cleaned with a cleaner such as TEROSON VR 10. Then apply a light coat of the product and allow the indicated evaporation time (5-10 minutes) to elapse before applying the paint. An example of a primer widely used for plastics is TEROSON 150.

Next, once sanded and clean, you can prime. We will apply TITAN Multipurpose Preparation Spray, a product that will guarantee an excellent adherence of the later painting. You can also use TITAN Yacht Primer.
It is important to know the type of plastic with which we are going to work, not all can withstand a spray primer. This is the case of very soft plastics, that is why we always advise to do a previous test in order not to destroy the plastic piece that we want to paint.
