The use of acrylic materials is gaining more and more popularity nowadays. But what do you need to know before applying acrylic to the surface? It is important to understand the significance of the priming process, its expediency, as well as what types of primers should be used in a particular case.
Application of acrylic materials
Acrylic is used in painting, construction, modeling, woodworking.
Acrylic is very convenient and easy to work with. It is an excellent coating for all surfaces or for painting.
You can paint with acrylic on any surface, be it paper, wood, plastic, hardboard, etc. All surfaces, except for white watercolor paper, require a preliminary priming.
Pre-priming is done for several reasons:
First, the adhesion of the paint to the material increases.
Secondly, the primer allows you to hide all material imperfections, for example, cracks and scratches.
And thirdly, the advantage of the primer is the achievement of a uniform paint coating.
Types of acrylic materials
For priming under acrylic, the following special primers are used:
Alkyd primer
It is considered the highest quality primer, after processing which a completely flat workpiece comes out. In some cases, a highly pigmented alkyd primer is used to create a semi-matt film and enhance color saturation. Traditionally used for coating wood and metal surfaces. Dries up to 24 hours.
Emulsion acrylic primer
Works for all materials except ferrous metal, as it does not protect against corrosion. Used for priming plaster, cement and concrete bases, wood, wood-vinyl and wood-shaving materials, brick, cardboard. It reduces the absorbency of the surface.
Has a high consumer value - practically odorless, diluted with water, dries quickly (2-4 hours).
Epoxy and polyurethane primers
These are the same epoxy or polyurethane paints that are pre-thinned with water. Dries up to 8 hours.
Shellac wood primer
On the cut of a tree, you can often see knots on which a resinous substance appears. Shellac primer serves as an insulating agent for stains that are previously dissolved in water. The basis for the manufacture of such primers is the milky sap of insects, with the addition of methyl alcohol. Dries up to 5 hours.
Primers for metal surfaces
Designed to protect metal from corrosion. A suitable primer is used for each metal.
There are several varieties of such a primer - zinc phosphate, zinc chromate can serve as a base.
Non-ferrous metals are usually sold pre-processed.
