APPENDIX A (required)

Table A.1

Purpose

The surface treated with the Nortex-Grunt primer has the following advantages:

• becomes stronger due to filling the smallest pores;
• there is a similarity with the material of the subsequent finishing, which improves the adhesion of the layers;
• prevents the appearance of cracks in the finish coating;
• not susceptible to microorganisms;
• saving subsequent material by blocking its penetration.

Acrylic primer "Nortex-Grunt" has universal strengthening and penetrating properties. Suitable for processing at all stages of finishing, from rough walls to finishing coating. These are the following types of base: wood, brick, stone, gypsum, concrete, wallpaper for painting, plaster, putty.

The use of acrylic primer increases the service life of the finishing coating and saves finishing materials such as glue, paint, and decorative plaster.

Excluding the priming step will compromise the integrity of the layers, and the decorative coating may peel and fall off. The lack of deep antiseptic treatment threatens the appearance of mold, darkening and other changes in the surface.

Working with Nortex-Grunt

Apply primer using a spray gun or brush. The recommended minimum ambient temperature is plus 5 degrees. If the surface to be treated is very uneven, full of cracks and seams, putty work must first be done, after which two layers of primer are applied. To dry the next layer, an interval of 30 minutes is maintained.

Further processing of the primed surface is carried out no earlier than an hour later, so that the primer dries well. And in cases of low temperature (less than 15 degrees) and high humidity (more than 80 percent), the drying period should be increased to a day. Doors and windows are covered with film to prevent the primer from getting on them and leaving stains.

The primer is tinted using color pastes used with water-dispersion paints. Primer consumption when applying one layer:

• for wood flooring – 90 g/m²;
• for concrete – 120 g/m²;
• for stone or brick – 120 g/m²;
• for plasterboard – 60 g/m².

Store “Nortex-Grunt” in a well-closed container, at a temperature of at least five degrees Celsius and away from heating appliances. Transport the primer in tightly closed containers. The shelf life of the soil is one year.

Why do you need a primer?

A primer is a specialized liquid composition applied to structures before subsequent finishing. The purpose of the primer mixture is to improve adhesion to the final finishing material (varnish, paint, plaster) and reduce the risk of mold and mildew.

The surface must be primed before applying any material: paint, plaster or tiles. This is an important process, if you skip it, you will be disappointed with the result of your work in the near future.

The most popular types of primers are universal. These are specialized mixtures that penetrate deeply into the base and make it stronger. And on the treated surface a polymer film is created that protects against moisture penetration and prevents the formation of fungi and mold.

Externally, primers resemble milk; they have a specific but mild odor. If stored inappropriately, such mixtures quickly lose their beneficial properties, which produces a more pungent and unpleasant odor. Proper storage is in a cool, dark place, in a well-closed container.

Specifications

What is the advantage of “Nortex-Grunt”? The technical characteristics comply with GOST and consumer requirements, the price of the solution is very affordable, and the quality of the coating is high.

Acrylic primer "Nortex-Grunt" has the following properties:

1. The color is white, it can be tinted in any shade to match the color of the finishing coating, which makes possible damage invisible.
2. When dry, the surface is colorless (without adding color).
3. The density of the solution is 1 g per cubic cm, which facilitates dilution while maintaining properties.
4. The alkaline balance of the composition is 7-9, which is close to neutral and safe for the skin.
5. Viscosity is 40-42 sec, which is convenient for application.
6. Consumption for wooden base or concrete 90 g per sq.m.
7. Consumption for plaster or brick 120 g per sq.m.
8. Consumption per hl 60 g per sq.m.
9. The minimum temperature for application and storage is not lower than +5°C.
10. Drying time 30 minutes.
11. Can be applied with a spray gun.
12. Shelf life is two years, including after opening, but in a tightly closed container.

The coating turns out colorless without the use of tint, and any desired shade during tinting. The choice of color depends on the finish coat. The manufacturer recommends computer tinting using the Tikkurila color palette.

Tinting the acrylic primer is recommended when covering with paint or decorative plaster so that the base does not stand out when chipping occurs. The “Nortex-Grunt” primer is thick, diluting it with a high-quality colorant will not affect its properties. Dilution is possible up to a 1:1 ratio.

The decorative properties of the acrylic primer "Nortex-Grunt" meet the high requirements for substrates for painting or thin wallpaper - the surface is smooth and fills all pores and cracks. The base is convenient for spreading paint and trimming wallpaper patterns.

Characteristics of the “Nortex” primer

Acrylic primer "Nortex-primer" is used before coating with water-dispersion varnishes and paints. Since the primer is made on a similar base, it forms a colorless coating on the surface and protects the coated material from atmospheric influences.

The acrylic primer lays flat on the surface without forming lumps, craters or folds. For subsequent painting, it is recommended to tint the primer mixture. recommends mixing paints.

Advantages of the “Nortex-primer” primer:

• water-dispersion base, which provides good compatibility with paints and varnishes on a similar basis;
• good adhesion (adhesion) of finishing materials to any treated surface;
• excellent protection against fungus, especially in humid environments;
• strengthening the base of the processed material by filling pores and cracks with a polymer suspension;
• increasing the service life of the paint layer due to strong adhesion to it;
• reducing the consumption of paints and varnishes and preventing their cracking.

Compound

"Nortex-Grunt", like all acrylic water-dispersion primers, is made on the basis of water, acrylic copolymers and a wetting agent. Special biocide additives increase the service life of the base and protect it from the harmful effects of the environment, while not affecting vapor permeability.

Compliance of the composition of “Nortex-Grunt” with sanitary, epidemiological and hygienic requirements is confirmed by a certificate of state registration and a quality certificate. Tests have shown its safety; the use of Northex acrylic primer is permitted in children's institutions and public places.

Additional Information

The "Nortex" primer is used to treat fragile and hygroscopic structures, this provides savings and uniform distribution of subsequent coatings applied to the surface. If you need to prime a smooth surface, then “Nortex” can be diluted with water approximately 1:1.

Take some precautions when working. If a certain amount of primer accidentally gets inside, the stomach is washed with water, then with a 2% solution of baking soda with activated carbon. Contact with skin is not recommended, otherwise wash with soap and water. Remove spilled primer with an adsorbent.
