Acrylic primer has its own special properties, thanks to which the product is additionally protected from environmental influences and corrosion. Consider why a primer is needed, its advantages, what types of soil exist and how to apply it.
Why is a primer needed?
A special liquid composition that is applied to the product immediately before the finishing process is called a primer. The task of acrylic primer is to improve the quality and appearance of the structure, as well as reduce the risk of mold or mildew in the future.
All surfaces must be primed before applying paint, plaster or tile. If it is not applied, then the appearance of the product will deteriorate in a short time as a result of exposure to environmental factors.
The primer applied to the product creates a special protective layer in the form of a film, which prevents the penetration of moisture, and, accordingly, prevents the formation of fungus. The liquid mixture resembles milky water without a specific odor. It must be stored in a hermetically sealed container and in a cool place away from the sun, otherwise it will lose its properties.
Benefits & Features
Acrylic primer is the most applicable material that is used as a filler. Due to its properties, the primer fills small defects on the surface that formed after grinding or puttying.
Acrylic-based paint can be used to process both plastic and metal products.
Advantages of using an acrylic primer:
- maximum surface leveling before the final stage of product finishing;
- due to the emergence of a protective film with the help of soil, a better connection of the putty and the paint occurs;
- when primed on a metal surface, it becomes less susceptible to rust and corrosion.
The primer is applied immediately before painting, which ensures the durability of the product, its heat resistance and resistance to external factors (precipitation, high humidity and sunlight). Most often, acrylic-based fluid is used in the automotive industry for application before painting vehicles. Ease of use allows you to use such a primer for both professionals and amateurs. Also, such a mixture is used in finishing works and furniture industry before applying paints and varnishes.
Varieties
Acrylic primer can come in different versions, depending on the purpose of the work.
- Impregnating primer based on acrylic and latex (this type is intended for use on a loose base and various plaster mixes, since it penetrates up to 10 cm deep).
- Firming fluid (its main task is not to penetrate deeper, but to create a special protective film, close the maximum number of cracks and achieve high quality and good appearance of the applied paint in the future).
- Adhesive based on acrylic (the most universal property that helps to level the surface).
- Organic (suitable for facade cladding, as it protects the product from environmental factors).
- Water-soluble (environmentally friendly, therefore suitable for all types of interior decorating).
In the automotive industry, a single-component, which is applied in a thin layer, and a two-component primer based on acrylic, which must be pre-mixed with a solvent and add a hardener, are used. There is also a separate anti-corrosion type that prevents rust on the metal, and a type that is applied to plastic surfaces so that they do not crack.
Application technology
It is easy to apply acrylic enamel primer. This will require a minimum of materials. It may be a brush, but it is better to use a roller for less fluid flow. Also, a container will be required, where the primer will be poured, and gloves. If some other component is added to the liquid (most often it is a solvent), then all this should be mixed in a separate container.
The soil has a high penetrating ability, so you should not fill the surface. If drops of primer accidentally fall on the wallpaper, traces may remain, so it is important to use it carefully.
The primer is applied on a flat surface with a foam roller, which saves both time and material consumption. If there are corners, they can be treated with a brush. Most often, the surface is primed not once, but twice. But before applying the second coat, the first should dry. This will take at least 12 hours.
What to consider when using
Experts recommend that when choosing and buying acrylic soil pay attention to its shelf life. On average, it is 2 years. An open container with underused liquid can be stored in a cool, dark room hermetically sealed for a year.
It is better not to buy a cheap primer, because it does not have sufficient viscosity and bonding properties. In order for the primer to form a protection in the form of a film, the surface before application requires maximum cleaning from dust and dirt.
To check that the soil applied to the surface has dried, you need to touch it, if the product does not stick, then you can proceed to further finishing. The surface is primed twice.
