Primer and paint are compositions applied to the surface of the objects. Each of these materials is their purpose. Consider the difference between the primer paint and is it possible during the works to replace them at each other.
The primer composition used to create the quality of adhesion between different materials.
Paint composition with which the surface of the objects creates a colored decorative coating.
Let’s dwell on the purpose of applying each of the compositions, because in this – the key difference from the first coat of paint. So, be sure the primer is used in cases when you need to cover any fragile material surface. For example, you need to be primed before hanging Wallpaper plastered wall. The composition will bind fractions of the plaster and make it much stronger.
In addition to strengthening the surface, primer ensures a tighter connection with it subsequently applied material. For example, paint or tile thus prepared will keep much better and will last for many years. But if the primer layer is applied to the metal, it also provides protection from corrosion.
What is the purpose of paint? The first is the creation of a decorative effect that we see when looking at the painted surface. But the paint function does not end there. Formed by the composition of the polymeric coating has a number of properties. It protects the Foundation from the adverse effects, prevents the rotting or corrosion of the material, to provide fire protection.

The primer contains little pigment. At the same time in the composition of this substance has special components which allows her to perfectly «stick» to different bases. This creates a rough surface which adheres very firmly other material.
In paint pigments constitute a significant part. The type of pigment determines the color of the coating and its resistance to a variety of factors. Also the paint contains a binder, which act as film-forming agents, and solvents that make the paint not so viscous and more convenient for the application.
Many wonder, what is the difference between primer and paint, hoping to save money. After all, cover the surface with two layers of primer would come out cheaper than to apply paint on the primer. Experts don’t suggest that you replace one part with another. Only «in the bond» they form an integrated system, where each component performs a specific task: the primer provides adhesion and impregnation, paint gives the film a gloss and ensures color fastness.
