In order for the painting to work properly, it is essential to properly prepare and clean the surface. Many times, however, we not knowing exactly what primer to use. In this post, we will explain how you can choose the right primer for your project.
What surface do we want to paint?
First, we need to clarify what surface we want to paint. Here you can choose from the following options:
- Plastic surface
- Wooden surface
- Glass surface
- Metal surface
- Styrofoam surface
- Already painted surface
- Rough, rough surface that we also want to seal
It is important to properly prepare the part to be painted on all surfaces, to remove greasy, dusty dirt. We recommend PintyPlus Alcohol spray for this (only clean alcohol-resistant surfaces).
Plastic surface:
It is not always necessary to use a primer for plastic surfaces. If the object is used for decorative purposes only, no special primer is required, just clean the surface and roughen it with a very fine sander to allow the paint to adhere properly. It does not need to be roughly sanded, because then we can lose the evenness of the surface. We recommend painting plastic surfaces with one of the water-based PintyPlus paint sprays, but you can also use the acrylic solvent version of PintyPlus Evolution.
If you consider that it is necessary to prime the plastic surface because the surface is very glossy or you want the paint to stick better, we recommend using PintyPlus TECH plastic primer spray. It is a colorless primer, so it can be easily applied to any surface.
Wooden surface:
In the case of wood surfaces, we recommend the use of a primer because on a raw wood surface the paint is very easily absorbed, so it is difficult to achieve a nice end result. You can also use 2 products here: PintyPlus TECH universal primer, available in white, red, and gray. Choose the color of the primer according to the color of paint you will use. For example, for black paint, use a gray primer. For red, brown, red, use a red primer. For white, yellow, green, blue, use a white primer.
Glass surface:
The glass surface, similar to plastic, does not always require priming. It is important that the paints adhere very hard to the glass surface, so we paint glass only for decorative purposes. Here, for better adhesion, we can use PintyPlus ART GESSO primer spray.
Metal surface:
For metal surfaces, you can choose from several options. If you only want to provide one physical protection, you can use PintyPlus TECH universal primer spray. If you want a little more serious protection, the use of aluminum and zinc PintyPlus TECH zinc spray, or in case of extra stress on the PintyPlus TECH zinc spray, as what we did the last course repainted rusted iron bars.
Styrofoam surface:
It is not necessary to prim the styrofoam surface, but it is important to use a water-based paint spray because solvent paints can corrode the surface.
In the case of an already painted surface, it is not necessary to re-prim, but make sure that the paint does not crack off the surface, because the new paint layer will only adhere properly if the underlying layer also adheres properly to the base surface.
If there are minor unevenness on the surface to be painted, you can level the surface using the PintyPlus AUTO spray. Blow on the surface, wait for it to dry, then sand the surface evenly with a very fine sander, then the paint layer can come. This product can be used on almost any surface.
