House, design, repair, decor. Yard and garden. Do it yourself

Usually each house has a pair-three of the brushes with which it paints everything: from the windows and doors to fences at the cottage. They also tinted batteries and lines wallpaper. Let's deal with what are the brushes and why they are suitable for.

Pilenk brush

Little tassel with a comfortable handle and rigid white bristles with a diameter of 6-18 mm. Suitable for painting hard-to-reach places or to outline lines during decorative work.

Radiator brush

The name itself suggests that this brush is intended for dyeing batteries. With it, you will get to all seams and bends.

Bristle

All brushes can be divided into three categories:

• Tassels with bristles made of natural fibers. Well absorbed and hold the paint, apply it to a smooth layer. Suitable for paints on an oil basis, olifes, varnishes and wood oils.
• Tassels with bristles from synthetic materials. Thin and smooth, suitable for water-based compositions: nylon fibers repulse excess moisture and retain their shape.
• Tassels with mixed bristles. Perfectly hold paint and do not lose form. They can be used for compositions and on water, and on oil bases. Ideal for outdoor work.

If you just bought a brush, then wash it before use hot water With soap - so you will remove dust and broken fibers. Then be sure to squeeze it and dry it.

Before painting something, leave a brush for an hour in the water. The bristle will become softer and swell, and the layers will fall smoothly. The main thing is not to put a brush in the jar, and hang it out, otherwise the bristle can be deformed.

If you have paint on an oil or alkyd basis, then dry the brush well before use.

So that the brush does not "cake" and did not leave the hairs on the surface, work on the brick, concrete or on the rough plaster before starting work.

If you used paints on an oil basis, first carefully rinse the brush in the solvent (kerosene, turpentine, whitecite), and then rinse with hot water with soap. If water-based paints - immediately go to hot water.

Many people do not even suspect that painting brushes and repair brushes are simply affected by their abundance and functionality. Usually use only one tool in all situations, but is it correct? So let's understand in detail what kind of brushes are.

Types of brushes

• Hanging (km) is huge fluffy brushes made of natural fibers and with the addition of synthetics (nylon), have a round shape. Their diameter is 60-65 mm, and the length of the hairs reaching up to 180 mm. Usually used for painting large surfaces, flushing or for spinning works. They have high resistant in contact with different solvents and other aggressive substances, perfectly carry high temperature differences and are not afraid hot water. When interacting with the working surface, they are a little bend, but then instantly straightened.

• Brushes-maclovers (CMA) - improved type of brushes that use glue or casein paint to apply various surfaces. They are based on natural horse hair (50%) and artificial bristles (nylon 50%), which allows you to evenly apply the coating layer on a certain surface. There are two types of such brushes: round and rectangular. Their diameter is 120-170 mm, and the length of the hairs is 100 mm.

• Brushes-handbones (CR) - these are small round brushes, apply for painting wooden windows or pipes. Their diameter ranges from 26 to 54 mm. Consist of pure bristles and horse-haired, have a round shape. The center of this tool is empty, which allows it to accumulate paint material. It is not recommended to use with adhesives and limestones, since the hairs are kept on adhesive basis. Usually this tool is called simply - painting brush brush.

• Pilena (FKF) is small brushes with a fairly comfortable handle and a rough white bristle. They are engaged on small surfaces to outline lines and painting difficult to reach. The diameter of the brush is 6-18 mm.

• Radiator - Wonderful paint appliance on inaccessible places: Stitches or bends. The name itself suggests that they are ideal for (radiators).

• Paint paint brush (CF) - flat wide brush from 25 to 100 mm with a comfortable handle. It is made of bristles and a barzuchea hair. Ideal for eliminating drills that could arise from other brushes.

• Brush Synthetic flat (KP), or brush flat with artificial bristles is a synthetic brush. It has a special property: its fibers, in contrast to natural fibers, retain their initial (level) form in the process of use. It is wonderful for paints diluted with water. Such a tool perfectly holds the composition not only on the outer part of nylon fibers, but also in the internal basis.

• Brush trim (butter) - a solid and very rigid brush, which consists of a damp or semi-quiet bristle. They are used to finish freshly abandoned paint. It very effectively eliminates all the irregularities applied by other devices.

Note: Brushes from the ridge bristles have the form of a cone, it allows them to capture more paintiness and evenly apply it to the surface.

The bristles made of natural fibers are ideal for painting works, well holds the composition, applying it a uniform layer. She is a little rough to the touch, which allows it to absorb more paints. This is what distinguishes it from artificial (nylon) hairs.

A bristles made of synthetic materials consists of polymers and has a small thickness. Different types of modern polymers allow you to achieve the desired rigidity. Nylon polyester bristle is perfect for water-intensive paints, its hairs do not absorb painting material, nylon pushes moisture and retains its original structure. In addition, the nylon is better suited for painting a bar, without leaving the Village on it.

If you take care of your tools and want them to serve as longer as possible, then you need to comply with certain rules for their storage and use. New or long-not operated paint brushes should be washed with hot water with a small amount of soap, it will help to clean the bristles from dust and broken fibers. After that, the bristle is squeezed and dry.

Before the immediate beginning of the painting work, you must soak up the bristle so that it absorbs moisture, softening and increasing in volume. Thus simple way You can achieve smoother and uniform paint.

Before starting painting work, the tool must be developed to accept it right shape. To do this, take a little painting mixture and the brush itself, as a test surface, you need to use any rough coating (brick, plaster, concrete). Thus, the hairs will find the right form for further work. The working surface is better to clear from all over.

It is very important to correctly clean the tool. For example, a round brushes on the working surface should be gradually scrolling in the hand so that its hairs erased evenly. It does not need to be very pressing it.

There are cases when a person is simply physically able to work out the entire surface. Naturally, he needs rest. At this time, the brush can be left in paint or immerse in a special solution. If glue, lime, oil and casein solutions are used, then soak the tool in water. With kerosene, turpentine or olive compositions, it is recommended to use special solvents.

It is very important: you need to immerse the tassel completely, but only to the depth, where the bristles are slightly touching the bottom, otherwise the hairs will be broken or worry, it is best to hang them on a wire or other device.

How to wash your brushes? For this we take kerosene, and then use water with soap. Such simple procedures must be continued until the water stops colored, remaining clean. At the final stage, hang them and dry them. The cleaning process is completed.

How important is the form of the brush?

Most people are accustomed to save their resources using old tools from time immemorial, but it is completely wrong. You just think that save, but it is not. For example, you can paint one surface with a small bristle with a round bristle. It is much more profitable to purchase a large flat brush that in one movement will paint an impressive surface.

HELPFUL INFORMATION: Types of kitchen hoods: What are and how to choose?

Round small tassel is more suitable for a small working surface. This tool allows you to cover special places, for example, round pipes. For hard-to-top places, it is recommended to use so-called angular brushes. It is important to remember that, first of all, you save time.

Paint brushes remain the most affordable paintwork tool. The cheapness and simplicity have a root side of the medal - low productivity and uneven paint. For getting high-quality coating One tassel cannot do, and it is necessary to have a set of different species intended for various types of paint, different shape of the surface and volume of work.

Paint brushes: types and applications

Flip and chicken brushes

Machova Brushes are distinguished by a large diameter (60-65 mm) and a length of the beam of hair to 100 mm, designed for coloring, primer or blots large squares. When sold in the form of a beam, then called weights, if they have a regular view - piece. Weighing brush subsequently tied up and make handles of the desired length. The ability to bend taken initial shape characterizes the quality of the brush. According to GOST 10597-87, they have the designation of the CM.

Spinning The brush, due to its 200 mm width and a thickness of 45-65 mm, increases the productivity of the blots and leaves behind the clean surface of the color.

Maclovterns and handbones

(CMA) It is used for painting large surfaces with water-based paints, can replace a chicken brush. It has a round (diameter of 120 -170 mm) or a rectangular shape (135, 165 width, 195 mm and a thickness of 55-65 mm). The length of the working part of the round form reaches 100 mm, rectangular - up to 80 mm. After painting such a brush, the surface does not require flue.

Brushes-handbones It can be with an oval form of a beam (Cro) or a round (kr) diameter of up to 60 mm. The variety of cattle has a round hair, narrowing towards an end to the cone. It is made of natural bristles with the addition of horse-haired, small sizes and a meek handle cause work with small areas. Suitable for most paint species, if the beam is attached using a metal ring. In the case of attachment with glue, such a brush is not used with adhesive and water compositions.

If the brush has a too big length of the working part, then when working it will be soft and inelastic, such a pile will leave after itself an uneven layer of paint, as a result - lowercases and furrows on the surface. Using twine or other materials, brush brushes are tied up to the desired length.

Flush and flat brushes

and flat Brushes (KF and KP) have a rectangular shape of the working part. Widely used when painting different species Paint coatings. Flots has a smaller thickness and leaves behind a more smooth and clean surface. Flat brushes, due to increased hair beam thickness, absorb more paint and apply for large areas. The width of the working part of flusted and flat brushes varies from 25 to 125 mm. The thickness in the flushes is 9-18 mm, in flat - 20-35 mm. With the help of flies with short hair apply lescing colors and achieve the effect of Moir with decorative finish.

Pile brushes and ending

Beam pilena Brushes (KFK) are made of round shape of a small size (8-18mm) of rigid pork bristles and is fastened in a metal cartridge. Designed for more accurate application of contour lines, narrow strips and painting in hard-to-reach places.

Brush-strikes (ART) is used to process just painted surfaces, gives a grungy look and is used for primer and decorative trim. Sizes of the rectangular working part: Width - 154 mm, thickness - 76 mm.

Species for special works

Brush for decorative trim

To a narrow flat brushes with a long curved handle and metal rim. Name radiator. This form allows you to paint the hard-to-reach surfaces of varying degrees of bend. It is not difficult to guess that they are used for painting heating batteries. The same brushes with a wide surface are used for external work.

A flat brush with a beveled pile is convenient when painting windows, and a dotted brush with a fastened bunch of a bundle, is used for tinted window frames.

For finishing edges and edges of painted surfaces, an edge brush is used. It is distinguished by the fact that bristled blocks can be changed.

Fan brushes in decorative and painting work are used for wide lines. Textural brushes made of pork bristles of various pile length are used in decorative trim. Can be made with linked beams. of different types Fibers that are connected in brush of different widths.

What makes paint brushes make

IN modern production Malanted and artistic brushes use such materials:

• Natural bristle. It has excellent ability to absorb and return all kinds of paint, except for water based paints. For the manufacture uses a ridge pork bristle. High-quality raw material assessment occurs with the help of measuring characteristics: elasticity, strength, length and thickness. The range of bristles reaches up to 77 mm long. The color is divided into: white, gray, yellow and black. White bristles is considered the highest quality and turns out by bleaching. The most important characteristic is the degree of natural splitting of the bristle.
• Natural hair. It has less elasticity and rigidity compared to the bristle, which is rarely used in pure form for painting works. Thanks to the scaled layer, perfectly absorb and give paint. Distinguish hard I. thin hair. Hard get from horse and cow hair, and a thin out of the hair of fur animals. The use of natural hair depends on the characteristics: length, shapes, elasticity, softness, wear resistance.

The history of the use of natural hair in painting has several millennia. At different times, rats were used rats, Lans, raccoon, hare, livestock, badger, bear and other animals

• Synthetic fibers There are thin threads from polyester, polyester, nylon and other connections. They have high resistance to mechanical damage, good softness and elasticity, but insufficient paint fence. This problem is eliminated with the help of artificial cleavage of fiber tips and the creation of additional channels in the cavity. It is used for all types of paint, including water based. Every year the quality of the synthetic fiber grows through the development of innovative technologies.

Mixed (natural and synthetic) pile apply for a combination better characteristics Two types - wear resistance and holding ability. In addition, using synthetic fibers, you can adjust the elasticity, softness and other properties of the brush.

Prices for painting brushes

The abundance of producers of painting brushes and rollers makes the buyer make a solution for each need to buy a paint tool. In addition to the elementary knowledge of the diversity of species and areas of their application, whenever it is necessary to choose the optimal ratio of price and quality.

The price of painting brushes and artistic is largely determined by the quality of the material from which the pitch is made. And there is no direct dependence on what type of pile is used: natural, synthetic or mixed. For example, professional flat brush American brand Wooster from nylon and polyester threads width 50 mm will cost about 1,100 rubles, while the brush from the natural high-quality bristle of the same manufacturer is 400-500 rubles.

In the device, the brush is installed in such a way that the middle of the beam is on the edge of the moving part of the device. Lower the movable part of the device. With the help of the stop, the brush is fixed in the device and apply a static load p:

- For brushes types of KR, CRS, km and KFK ... 49 N (5 kgf),

- for brushes of types of Cro, KP and KF ... 29.4 N (3 kgf).

The static load p is made from the weight of the cargo and the moving part of the device.

The cross-sectional area of \u200b\u200bthe beam is determined by the scale of the device.

Construction technologies are developing, but in the field of painting works, rollers and brushes are still basic tools. We were dedicated to the rollers, and now let's talk about the brushes, their diversity and how to apply them for various works.

The most common and popular option are flints paint brushes (CF). They are familiar to everyone who somehow came across the painting walls, slopes, windows and other surfaces.

Flushes flat, spatula, bristles are reliably fixed with metal tightness. Usually the length of the bristles is 60 millimeters. Flat tassels are more convenient in operation, there may be different sizes, so you can buy several at once so that a wide brush to paint the free space, and more subtle - window crossbars or ceiling plinths, eg.

The handles in flush brushes can be plastic or wooden, they are also flat, ergonomic and are well lying in the hand. Specialists in painting work noted that a flat brush-flutz can absorb a sufficiently large amount of paint, this allows not to do strokes too often, eliminates the appearance of herds. Flots makes it possible to apply paint in any directions, with proper technique, the spray will not. Such brushes are used with all kinds of paint, varnish, olphoua, enamels.

The opposite of the Flens looks like fililent brushes (KFK). They are round and small diameter. For the color of the walls and other large surfaces, they are not suitable, usually fililene brushes are used where delicate work is needed, for example, to apply screen drawings on the already painted surfaces. In addition, the fililent brushes can be used to pull the fillets and applying paint into hard-to-reach places, much more thick brush just does not reach.

Handes (cr). Round brushes that can have a different diameter, usually from 30 to 50 millimeters. Smoothly staining the surfaces, can be used for priming, color of bottlenecks and in small areas.

Urinary brush. Traditionally, used for blissing, washing walls, blur blell. Now such brushes are usually made from the bark of a linden, purified from bitch and exposed in the tank where air did not sit down. Fibers are separated on thin strips and are wounded in a brush. Water or a solution of urinary brushes hold well, but when working with them it will be very difficult to avoid splashing.

Oval brush. It is considered vocational and beginner painters used infrequently. Oval form allows you to apply strokes and by narrow surfaces, and wide. Typically, the tissue ratio is 1: 2, that is, simply by turning it in the side, you can get twice wider or narrow bristles.

As for the bristle itself of painting brushes, it can be natural and artificial. For example, soft bristles are usually used for thin viper brushes, which is made of a hair column or protein. The best hard brushes are considered to be created from the semi-republic or ridge bristle. They are less spraying the beauty and gain more painted composition. But there are such brushes from the natural range of bristles are usually more expensive.

Cheaper brushes created from horse's hair, but their pile quickly loses flexibility and falls off, they will not serve. Synthetic fiber - not bad option, proper use Such a brush will last long. But artificial brushes hold less paint, it can drip on the floor, the flow rate is slightly higher.

To check the quality of the bristles, it should be bent it - it must quickly restore its original shape. The hairs should not be strained, they are evenly and smooth. The split ends of the bristles and the loss of hairs immediately after the first flexion are unacceptable.
