Composition and technical characteristics of the GF-021 primer
GF-021 primer is a universal composition. According to the form of release, it is a suspension. Basically, it is a liquid containing solid particles. Its density is 1.25-1.3 kilograms per liter.
In accordance with GOST, the mixture includes the following components:
- drier;
- stabilizer components;
- alkyd varnish;
- pigments;
- corrosion inhibitors;
- minerals;
- other additives.
GF-021 helps protect surfaces from external factors.The substance is suitable for processing various types of surfaces - metal, wood, plastic. The primer can be applied at the stage of preparing the material for paint application or to create a protective layer against fungal microorganisms and corrosion.
GF-021 Primer Mix is an alkyd coating. The material does not absorb into the substrate and helps achieve an even, thin layer.
Certificate of conformity
The technical parameters of the composition are regulated by GOST 25129-82. Only a primer of gray color has a different passport - it is prepared in accordance with the technical conditions.
According to the law, each batch of material is certified. Thus, a certificate of conformity with a decoding of the parameters, a quality passport and a safety certificate are attached to the packaging.
Packing and Release Form
The primer is sold in 900 gram and 2.8 kilogram containers. Also on sale are containers with an industrial volume of 25 to 250 kilograms.
The tool is produced in the form of a suspension - a liquid containing solid particles.
Color pallet
The GF-021 floor is produced in a red-brown palette. It is also produced in light gray colors. On request, it is possible to manufacture a black product. Color saturation varies by batch.
Storage Features
To maintain all the technical parameters of the floor, you must follow certain rules that are given in the instructions. Material should be stored in an airtight container away from heat sources. The substance is afraid of high humidity and direct sunlight. The shelf life is 2 years.
Purpose and properties

Advantages and Disadvantages of Requesting Seed Jobs
The advantages of the primer mixture are:
- resistance to strong temperature fluctuations - the composition is able to withstand temperatures from -45 to +60 degrees;
- reliable masking of small cracks and irregularities;
- forming a resistant coating;
- the ability to use as an independent topcoat;
- resistance to the influence of mineral oils, detergents, water, substances containing chlorine;
- prevention of corrosion of metal surfaces;
- high abrasion resistance;
- profitability.
At the same time, the mixture also has some disadvantages. These include in particular the following:
- lack of penetrating properties;
- a long period of complete drying - more than a day;
- poor tolerance to very low temperatures;
- short life - it is usually less than indicated.
How to calculate material consumption
To apply a primer in 1 layer, you need to use 60-100 grams of primer per square meter. However, the exact throughput depends on many factors.
These include in particular the following:
- configuration of the painted surface;
- quality of coating preparation;
- the staining method used;
- used equipment;
- employee experience;
- Terms of use.
Tools required
Different tools can be used to apply the primer. This may require the following:
- roll;
- brush;
- spray gun.
Rules for surface preparation and working solution
Before performing the bootstrap jobs, you must do the following:
- Shake the composition to obtain a uniform density. Further, the primer is diluted with a solvent. When forming a dense film, it must be removed from the surface of the composition.
- Before priming a metal surface, it must be treated with special sandpaper or special compounds and degreased. When applying a primer to an old metal surface, it must be cleaned of rust.
- There should be no cracks, protruding joints or sharp edges on the surface to be primed.
Substances that can be used to dilute the mixture are indicated on the packaging. They are used if the viscosity exceeds the permissible parameters. For primer GF-021 it is allowed to use substances such as xylene, turpentine, solvent. You can also use white spirit.For use in an electric field, the composition RE-3V, 4V is suitable.
The proportion of solvent must not exceed 25% of the weight of the primer. After the introduction of the substance, the composition must be thoroughly mixed.
GF-021 Primer Application Technique
The instructions indicate that you can apply the primer mixture with different tools. For this, it is permissible to use a brush, roller or spray gun. Watering techniques are also allowed. A good solution would be the jet pouring method.
It is recommended to apply the primer in 2 coats. It should be done gently, without making harsh blows. In this case, the thickness of the layer, as a rule, does not exceed 18-25 micrometers.
It is allowed to use the primer only in well-ventilated rooms, since the substance has a pungent odor. For safety reasons, gloves must be used.
After drying, the primer becomes dull. It is allowed to use it as a base coat or to cover it with enamel. Before subsequent coating, the surface must be sanded. As a result, it will become smooth, and the paint will lie flat.
For wood
Wooden surfaces have a porous structure. When using a primer, it is possible to increase the degree of adhesion of materials. This effect is achieved by clogging the pores and leveling the surface of the wood. The primer has a fairly low viscosity, which helps it penetrate pores. In this case, the thickness of the applied layer should be small.
For metal
GF-021 primer has high anti-corrosion properties. Therefore, it can be applied to metal surfaces. The undercoat will help improve the adhesion and anti-corrosion performance of the substrate. After that, it is worth applying enamel, which increases the protective properties of the coating and gives a decorative effect.
For concrete
Concrete pavement generally has a loose and weak structure. The use of GF-021 primer makes it possible to firm the surface and smooth its relief. In addition, the substance creates an adhesive intermediate layer for the application of finishing paint and varnish. It is also possible to obtain moisture absorption from the base. This prevents the active development of fungi on the surface.
On loose substrates, the primer should be applied in 2-3 layers. The exact amount depends on the looseness of the surface. In this case, the first layer penetrates deep into the pores, and the soil is used to strengthen the substrate. The following coats help to smooth the relief and improve adhesion.
Drying time
The drying time of a primer depends on many parameters, the main one being temperature. At +20 degrees it takes 24 hours to dry 1 layer of material, at +105 degrees it takes a maximum of 35 minutes.
Possible errors
When using a primer, inexperienced craftsmen make various mistakes that negatively affect the result:
- Too much primer applied. If the thickness exceeds the standards specified in the instructions, complete drying may take more than 2 days.
- Does not support the drying time of the diapers. This leads to a significant decrease in the adhesion parameters of the coating.
- Apply the primer in an uneven coat. As a result, the coating is characterized by uneven drying.
- The surface is not properly prepared for the application of the substance. As a result, the primer peels off.
- Do not use degreasing agents at the stage of preparing the base. Such formulations help remove greasy stains and rust-causing substances. If you ignore the use of such compounds, the level of adhesion of the floor to the surface is significantly reduced.
Security measures
GF-021 Primer is considered a flammable material. In addition, it contains diluents which have toxic properties. The vapors of these substances present a real danger to people. Therefore, the primer cannot be used without personal protective equipment - gloves, special clothes and a respirator. It is important to ensure that the primer and its vapors do not come into contact with the skin, mucous membranes or the respiratory tract.
When carrying out priming work, it is important to strictly observe fire regulations. Workshops must have fire protection equipment. When applying the composition, smoking and the use of fire are prohibited. If the substance comes into contact with the skin, this area should be rinsed with plenty of water. After drying, the coating does not pose any danger to people.
Recommendations from the masters
When using the GF-021 primer, a number of features should be considered:
- This brand of primer is only available in a red-brown shade. The gray formulations are produced exclusively according to the manufacturer's specifications.
- When choosing and buying a primer, you should give preference only to high-quality materials. Some brands use cheap raw materials or strongly deviate from production technology.
- GF-021 primer should be made in accordance with GOST and contain alkyd film-forming agents. Using a primer based on oleo-polymer varnishes will not provide the required degree of adhesion and reliable corrosion protection.
GF-021 primer is a common agent that provides high adhesion parameters and helps strengthen the surface. It is important to follow the instructions carefully to achieve the desired performance.
