One product that is frequently used in the paint and coating industry is GF-021 primer. Well known for its dependability and adaptability, it acts as a basic primer for a variety of surfaces, improving the adherence and strength of later paint coats. Painting projects can turn out much better if you understand its properties and appropriate applications.
The superior protective properties of GF-021 primer are among its most notable benefits. It is the best option for metal surfaces because of its strong resistance to rust and corrosion. It also offers a uniform and smooth base, which is necessary to achieve a perfect finish when using topcoat paints. Like any product, it does have some disadvantages, though, and being aware of these will help you choose wisely.
GF-021 primer is available in multiple varieties, each designed to meet particular requirements and circumstances. Every material you work with, be it wood, metal, or another, has a version that’s optimized for longevity and performance. It is imperative to comprehend the distinct technical attributes of each type, including drying times, application techniques, and coverage rates, in order to utilize them efficiently.
When using GF-021 primer correctly, it’s important to adhere to a few guidelines and best practices. Every stage of the process—from surface preparation to application—is essential to getting the intended outcomes. Using the primer correctly not only extends its useful life but also improves adhesion and durability of your topcoat. You can improve your paintwork projects’ longevity and quality by becoming proficient with these guidelines.

Features of the primer GF-21
Alkyd varnish is used to make coatings that are strengthening and protective. Glypttal resin, which is produced by polycondensing glycerol with ftalt acid anhydride, is used as a binder.
primer GF-021
- The primer is a suspension of fillers, coloring pigments, sequcathives, stabilizers with the addition of a solvent.
- The solvent gives the suspension the necessary viscosity, which provides penetration into the upper layer of the processed material, reliable grip with the surface and the formation of a strong, uniform film without fluxes and influxes.
- As a solvent, solvent, white spite, xylol, acetone, turpentine or their mixture are used.
When priming metal components and structural elements, the RE-1 solvent is used to increase primer adhesion and prevent corrosion on the metal components.
solvent
By weighing the primer and solvent in a 1:1 ratio, the required viscosity is achieved.
A prepared, cleaned surface of metal or wood is covered with a layer of primer mixture. It completely penetrates the substance, fills in micropores and microcracks, evens out the surface, and gives it strength, smoothness, and evenness.
primer GF 021 gray
This enables you to use twice as much putty, varnish, and wallpaper adhesive. Priming stops the metal from corroding, lessens wood’s porosity, creates a uniform wooden surface, and guards against the growth of mold and insect lesions.
Technical characteristics of the GF-21
The recommended temperature range for using the GF -21 primer is -45 0 C to +60 0 C. The resulting film is colored gray or reddish-brown. The layer should be homogenous, smooth, even, matte or semi-glossy, free of influxes and pompers after it has fully dried.
concrete mixtures for external work
- Viscosity by a viscometer with a nozzle diameter of 4 mm at a temperature of 20 0 with at least 45 seconds.
- The mass fraction of the solid residue after drying 54-60%.
- The size of the particles of the filler, pigment and sequcathives is not more than 40 microns.
- The drying time to the possibility of applying a second layer or paintwork is 24 hours.
- Forms a film with a solidness of 0.35 conditional units according to a pendulum device.
- The elasticity of the film on the bend is 1 mm.
- Adhesion of a formed dried-up film of more than 1 point according to GOST 25129-82.
- Resistance to water, aggressive media and detergents for at least 24 hours.
- After drying, the film can be sanded with fine sandpaper.
A precipitate that easily stirs before application can form when storing a ground emulsion. Long-term storage raises the density to the point where more solvent must be used when diluting.
Crucial! The primer is categorized as a toxic substance. Wearing personal protective equipment (PPE) for exposed skin and respiratory organs is mandatory when using it.
Ground emulsion
When the concentration in the working area’s air reaches 50 mg/m3, the primer’s inflammation temperature is 36 0 s. As a result, a room with adequate ventilation is required for work.
A robust, long-lasting protective layer will be produced by the primer, varnish, and paint all having the same alkyd composition.
Soil for metal
Functions of the primer GF-21
The GF-21 layer is applied to metal, wood, plywood, chipboard, fiberboard, and MDF surfaces to prepare them for varnish, paint, and enamel application. It also forms a protective layer against fungi, corrosion, and insect infestation of wood.
- Low cost with high quality in compliance with the characteristics of the specified in the GOST and that.
- The ability to use in external and internal work.
- Increasing moisture resistance of the covered surface.
- Reducing the flow of paint and varnish material, wallpaper glue, putty.
- The ease of applying accessible painting tools, carrying out work does not require special skills and preparation.

By deeply penetrating the pores between the fibers and cementing the top layer, priming fortifies the wood’s fibrous structure. This shields soft materials from mechanical damage and stops wooden products and structures from deteriorating due to moisture.
Because a strong, solid film is formed when the primer mixture is applied, it improves the adherence of decorative or finishing materials to the treated surface.
By shielding wood from moisture, it stops shrinkage cracks from forming. forms a barrier that prevents corrosion on metal products and structural elements.
When in use, decorative finishing material does not develop cracks, peeling, or abrasions; instead, it lies in an even, thin layer without pouches or influxes.
solvents
The treated surface’s strength is doubled by the primer.
While there are a few things to keep in mind, GF-021 primer is an excellent option for a variety of painting tasks. Its outstanding adherence is its main benefit as it offers a strong base for later paint layers. This quality guarantees a long-lasting and robust finish, which is especially important for surfaces that are prone to wear and tear.
Additionally, GF-021 primer is available in a variety of formulations to accommodate a range of substrates and application needs. There’s probably a version made specifically for your needs, whether you’re working on concrete, metal, or wood surfaces. Furthermore, choices like formulations that dry quickly improve productivity and enable a quicker project completion time.
However, GF-021 primer has its limitations just like any other product. Its strong odor may be disagreeable to some users, so when applying it, make sure there is enough ventilation. Furthermore, even though it has excellent adhesion, for some metal substrates it might not offer enough corrosion resistance on its own. As such, it’s critical to evaluate the particular requirements of your project and, if needed, take additional coatings into consideration.
Comprehending the technical properties of GF-021 primer is essential for the best possible application. Everything from drying time to viscosity affects how well it works and works with various painting systems. To achieve the intended results, it is essential to adhere to manufacturer guidelines regarding environmental conditions, application methods, and surface preparation.
Finally, GF-021 primer exhibits excellent adhesion and versatility, providing a dependable base for a range of paintwork projects. Making informed decisions to guarantee successful outcomes requires weighing the benefits and drawbacks of each option against the requirements of your project. Its effectiveness is maximized when usage guidelines are followed, making integration into your painting process easy.
In the world of paint and coatings, GF-021 primer is a flexible and popular product with a number of benefits, including good adhesion, resistance to corrosion, and affordability. This article covers the various varieties that are available, delves into their advantages and disadvantages, and highlights their salient technical features. It’s a must-read for DIY enthusiasts and professional painters alike because it also provides helpful application guidelines for the best results.
