Because of its adaptability, it can be used for a wide range of projects, including metal structures and furniture restoration.

The application of GF-021 is simple. It can be applied to the surface by brushing, rolling, or spraying, and for best results, usually just one or two coats are needed. Make sure the surface is clean and clear of debris, grease, and old paint before applying. The quality of the final finish and the effectiveness of the primer will both be improved by proper preparation.

All things considered, primer GF-021 is a necessary tool for producing a polished and long-lasting paint job. It’s an essential product for anyone hoping to achieve high-quality results on metal and wood surfaces because of its protective properties and ease of use.

Description of the material

The primer GF-021 is a material that can be used anywhere because it is a suspension, or a liquid that contains solid particles. GOST controls the mixture’s composition; the soil contains:

• alkyd varnish;
• sequacative;
• mineral substances;
• stabilizing additives;
• pigments;
• corrosion inhibitors;
• Other fillers.

Because the primer is an alkyd, or glyftal, type, it does not absorb into even the most porous surfaces, such as wood. Following the processing of the latter, a unique layer—a film—is produced to offer defense against exposure to the outdoors.

Soil properties and its purpose

On various surface types, the primer’s use is warranted. Paint, enamel, varnish, and other materials can be used as an independent coating or to set the groundwork for later work, which helps to cut down on consumption by 1 kV. On these surfaces, using the GF-021 is acceptable:

• wooden;
• metal;
• plastic.

To stop the product’s spread, you can apply it to concrete, faner, MDF, chipboard, and rust is acceptable. The product will shield metal buildings, automobile frames, household goods, and goods that are being produced from moisture, fungus, and microbe activity. The walls of homes and other buildings can be protected outside the room by soil because of its "endurance" to temperature changes.

Pros and cons of the product

The material’s exceptional quality dictates the characteristics and attributes of the primer GF-021. The following are its benefits:

• powerful anti -corrosion action;
• resistance to adverse atmospheric conditions;
• quick drying;
• reliable protection against various chemicals – household chemicals, oils, lubricants, aggressive liquids;
• the ability to use in high humidity;
• a serious improvement in adhesion between the base and subsequent layers;
• decrease in the flow of basic material.

The material works well with all common paint types, including oil-bitumen, alkyd, and other paintwork. For instance, it’s frequently applied beneath the PF-115 alkyd enamel.

There are some drawbacks to the remedy. As the manufacturer stated, the primer is drying quickly. By standard, it takes a day for the primer to fully dry. However, in practice, this time frame might lengthen, and allowing temperature swings to occur while drying is highly undesirable. Another drawback is that not all paints dry completely before applying them to the ground. For this reason, it’s crucial to let the coating dry completely.

Primer characteristics

The product’s technical specifications are listed in GOST 25129-82. The only soil that differs is gray soil, which is prepared in a manner other than that of GOST. The key indicators and the data transcript are described below.

GOST data

Applying to the base produces a high density film that appears matte or slightly glossy, even, and homogenous without any unnecessary inclusions. The following are the general characteristics:

• Conditional viscosity according to the device viscosimeter ZA-4 at a temperature of +20 degrees-45 C;
• the need to dilute the primer is no more than 20-25%;
• the content of non-volatile substances-54-60%;
• relic – up to 40 microns;
• drying time to the third degree at temperatures up to +105 degrees – 35 minutes, at a temperature of +20 degrees – 24 hours;
• Film hardness according to the M-3 device-0.35 units;
• elasticity for bending – 1 mm;
• The strength for a blow to the device U-1-50 cm;
• adhesion of the coating – 1 point;
• Resistance to the action of sodium chloride 3% – 24 hours, to the action of mineral oil – 48 hours.

The soil layer has a thickness of 15-20 and is typically applied to two layers, the second of which may be slightly thinner.

Shades

Colors of the GF-021 primer: light gray, red-brown. It is possible to produce a black agent on demand. The characteristics of a given batch’s production determine the shade’s depth.

Storage

The soil has a two-year shelf life. Simultaneously, it is crucial to adhere to the storage requirements, which include being in factory banks with up to 80% humidity and no access to sunlight. The material can be frozen (up to -20 degrees), and this won’t affect its characteristics.

Safety

The manufacturer claims that because of the dilutors, the soil is toxic and flammable. The primer is not meant to be used without personal protective equipment (gloves, respirator, dense clothes), as these substances pose a direct risk to humans. It’s critical to wear protective gear against soil fumes:

• skin;
• Airways;
• The mucous membranes.

Fire regulations must also be closely followed. Fire safety supplies should be available in the workshops since smoke is not an acceptable method for priming and painting surfaces. Rinse the skin with water right away if any of the material gets on it. For humans, dry coating is perfectly safe.

Certification

Every batch of material should be required by law to undergo certification. To any bank holding the funds, applications are made in this regard for a certificate of conformance, quality passport, and security certificate (hygienic certificate). The soil is packed into 900 g, 2.8 kg containers and 25–250 kg industrial banks.

Proper surface preparation

Because of its uniform, pleasing shade, the product can be used in place of staining when processing metal structures. The finished film will be easily ground and smooth. If the surface is properly prepared, then all of these requirements are met. You must perform the following in order to do this:

• clean from rust, pollution, old paint with a mechanical method;
• Remove fat spots, dust;
• exclude the presence of burrs, seams, cracks, craters;
• Window, door openings should be covered with construction tape if work is carried out inside the room.

Primer GF-021 is a dependable and adaptable option for surfaces made of metal and wood. Its main goal is to better adhere and provide a more durable finish by priming these materials for additional painting. This primer, which is a necessary step in any painting project, helps to improve the appearance and longevity of the topcoat by forming a smooth and even base.

When applied on metal, GF-021’s ability to prevent rust is one of its main advantages. The integrity of metal structures must be preserved, and it does this by shielding the metal from corrosion. By sealing the porous surface, stopping the paint from soaking in, and lowering the number of coats required, GF-021 creates a strong foundation on wood.

The application of GF-021 is simple. Depending on the project’s size and requirements, a brush, roller, or spray gun can be used to apply it. The painting stage can be completed quickly because the primer dries rather quickly. For optimal results, make sure the surface is clean and clear of dust or grease before applying.
