Regardless of its composition, for all paints and other coatings decorative coatings there are some rules that they must comply. They should be easy to be simple to maintain, without prejudice to endure dry or wet cleaning, be ekologicheskichistymi, convenient in application. In addition to these qualities, to many kinds of materials are subject to additional requirements - high resistance to wear in heavily used areas, moisture resistance when used in bathrooms, kitchens, etc. In addition to the performance of coatings on the buyer's choice is largely influenced by the properties of decorative coatings, such as color , texture, luster, etc., as well as the cost of coverage. Decorative paint properties color. Modern paints can have almost any shade. Each manufacturer of paint products, there are special directories that list thousands of shades, each izkotoryh has a number, and you can get virtually neskolkominut with special tinting machine. The degree of gloss is also in wide limits: paint can be high gloss, glossy, sredneglyantsevymi, etc. dopolumatovyh, matt and deeply dull. In recent years, the greatest demand is matte paint. Texture coating is achieved is not necessarily due to special properties of the paint, but also thanks to a special application technique. Sometimes the textured coating is capable of creating the special optical effects on the walls, light and shadow, the apparent change in color depending on the angle and the degree of illumination. Technological properties of paints Opacity - a very important feature of using kotoruyumozhno analyze the different colors. There is an international standard ISO 6504 / 1, which states that the coverage - this area kotoruyumozhno evenly cover one liter of paint so that it overlaps 98% of the substrate, contrasting painted black and white squares or stripes. There is a similar characteristic is opposite in meaning - consumption: the amount of paint needed for covering up to 98% of the contrasting area of ??1 sq. m. However, this feature suschestvennomenee objective than the coverage, because it depends on many factors. Technology application, surface features, qualification painter, selected tools and even the temperature can affect the flow of paint. Hiding power of paints has a wide range: from staining, ie, transparent to opaque paints. Adhesion - a paint adhesion to the painted surface. High adhesion of the material - an indispensable condition for establishing high-quality paint. Good adhesion is ensured, in addition to the properties of the paint itself, the correct surface preparation and staining to the technology. Viscosity, or consistency, - an important parameter of quality refinishing. Too thick paint will go lumps, too much liquid can have a low hiding power and adhesion, which osobennovazhno for vertical surfaces, which may appear smudges. It is very important to consider the viscosity in the case, if you plan to apply paint using the spray. Drying time - an important process parameter for all coatings. As a rule, the approximate time of drying indicated on the packaging. However, this information should be taken only with the amendment to the specific operating conditions: humidity, temperature, substrate temperature, etc. The drying time of paint also depends on internal factors: viscosity, himicheskogosostava paint, etc. Drying time of paint directly affects the speed of work. Thixotropy - the property to increase the fluidity of paint mixing. Thixotropic additive in the paint make it more convenient in application: it is well distributed over the surface and not dripping with a roller or brush. Paint with good thixotropy forms a smooth flat film, leaving no stains. Environmentally friendly. Paints containing volatile organic solvents are harmful to health. Water-dispersionnyekraski are clean and quick-and therefore preferred to work, especially indoors. In any event, no matter what paint you choose, should strictly comply with all instruktsiipo use and safety. Performance properties of paints There are 4 class interior paints in accordance with the terms of coverings. 1 class. Paint, which imposed minimum performance and decorative requirements. This is - paint applied in a dry place, do not experience particularly significant external influences, such as dry basements, warehouses, archives, etc. Paints 1 goklassa usually do not differ special decorative effect, most often they are quite dull. The main requirement for such paints - their good coverage. Grade 2. Paint used in a domestic environment, they paint the walls dry rooms with standard room climate. Paint in class 2 are used in bedrooms, living rooms, etc. The main requirements to the properties of paints - good coverage and resistance to washing and mechanical wear. Requirements for decoration - moderate. Grade 3. Paints, which are increased requirements during operation. They are used in dry and wet areas for painting surfaces experiencing strong external impact. Paint the third class are suitable for use in kitchens, bathrooms, stairwells, public areas, etc. The main requirements for paints third grade - high durability, resistance to mechanical stress and water resistant. Grade 4. Paints for surfaces exposed to the maximum impact - a strong effect water mehanicheskomuiznosu and the action of aggressive chemical media. Paint Grade 4 used in the kitchen, showers and bathrooms, bath houses, in doorways, at factories, chemical laboratories, stairwells, and so on. Requirements for paints of this class as good: they must be water-resistant and durable to withstand the action of chemical reagents, have антисептическимисвойствами (to prevent the appearance of mold, fungi, colonies of microorganisms). Fastness, its types (chemical, biological, etc.) Moisture resistance of paint - the ability of paint to keep all their properties at a more or less strong influence of moisture. Moisture resistance of paints is a wide range: from absolutely nevlagostoykih inks (matte powder coating, easy to traumatic when wet) to a water-resistant washable paint (gloss finish). When choosing colors should not automatically choose the most water-resistant paint from all possible: water-resistant paints give a glossy finish and gloss emphasizes all the irregularities of the walls. Matt, good masks irregularities, but a matte finish can be both washable and does not tolerate water. Resistance to washing - characteristics similar to water resistance. Resistance to washing and abrasion estimated number of brushings certain rigidity in the wet or dry form before the first violation in a colorful cover. Durability - resistance of paint to a periodic mechanical stress (abrasion, trampling, etc.) Light resistance - the property of paint to transfer the effect of light without changing its properties. Paints with low light resistance may fade or turn yellow in the light, then they are recommended only for areas with weak artificial light. Paints with high light fastness can be used as a facade. Weathering - the ability to paint resistant to weather conditions, combined - sunlight, changes in weather conditions, rain, snow, exhaust b industrial gases in the atmosphere of cities, changes in temperature and so on. Paints with good atmosphere suitable for facade work in big cities. Paints with low atmospheric stability should be used for interior work in confined spaces. Chemical resistance - the property of paints to be inert to chemical attack. There alkali, acid and other dyes. Chemical-resistant paint used in chemical laboratories, hospitals, washing offices, industrial facilities, where the painted surface periodically comes into contact with various chemicals, strong detergents, disinfectants and other biological stability - the ability of paint to resist biological corrosion. To paint a possessed biological stability, it added a special antiseptic, fungicide and other additives that protect the coating from the education on or under a coat of paint mildew colonies of microorganisms, fungi, etc. Remember that the biological corrosion is easier to prevent than to deal with it when it manifestations have become apparent. Special properties of paints Paint coatings may possess, in addition to those listed, and special properties, given to them in accordance with naznacheniempokrytiya. In the group of coatings with special properties include heat-resistant, thermostatically controlled to protect against X-ray, electrical, chemical inertness, antibacterial idrugie. These paints are used on the premises for which is necessary to have a special coating properties.
