PAINT BRUSH CROSS-SECTION

BRISTLES

Chinese bristle
This bristle is obtained from Chinese pigs in natural white or dyed black or gray. It is one of the most popular materials for the production of paintbrushes (both smaller and bigger ones). Thanks to its features this bristle is particularly appropriate for work with synthetic paints and varnishes. This bristle has rough surface and it is flexible with conical tips.
This bristle does not have only have one tip but it is frayed into two or three tips, the so-called "flagging".

All this sets up a thick and soft structure that ensures a very good paint application.

Synthetic bristle
Beside natural bristles, synthetic plastic bristles (nylon, polyester) are starting to assert themselves to a high degree. For brushes (bigger ones) cylindrical synthetic not thinner resistant bristles and cylindrical nylon bristles with artificial fraying are produced. For brushes (smaller ones) pointed frayed conical plastic bristles are used. Brushes made from these materials are especially appropiate for work with acrylic and water-based paints such as glazing and wood preservation agents. Modern synthetic bristles are very durable and resistant and assure optimal working results.

Bristle OREL with Chinese bristle
This is a mixture of the quality Chinese bristle and the bristle OREL from Du Pont. The bristle OREL is a high-quality polyester bristle with a special profile that has a high absorption and a smooth release. The proportion of bristles was developed particularly for water-based paints and varnishes. It combines the advantages of the Chinese bristle and the bristle OREL and it helps prevent the brush from failure caused by swelling up of the Chinese bristle when using water-borne paints and varnishes.

Chinex plus
Top quality for professional work. This name refers to a top-quality new synthetic fibre developed by Du Pont in the USA (a conical nylon fibre - 612 ). It is mainly intended for brushed used for painting with water-based paints and varnishes. Chinex fibres have a conical round shape, their tips are pointed and frayed. These features resemble the Chinese natural bristle. While working with these brushes the bristles renews itself by splitting of so-called "breaking off points" which enables the bristle to preserve its tenderness. Chinex fibres have an enormous abrasion and bend resistance and in this aspect they  exceed even the Chinese bristle. They also accept less water than natural bristles and therefore they do not swell up when painting with water-based paints. After the work has been finished Chinex brushes are easier to clean than brushes with natural bristles.

NYLON

Velice odolný materiál. Používá se zejména na odrezování a odstraňování starých nátěrů agresivními přípravky.

PVC (polyvinylchlorid)

Syntetický materiál používaný především na zednických štětkách. Nedrží v sobě tak dobře barvu jako pravá štětina, ale je cenově velice příznivý a má dlouhou životnost a dobrou odolnost proti odírání. Pro zlepšení vlastností se používá tzv. „štěpené PVC“ -> konce vláken jsou rozštěpena, čímž dosahujeme daleko lepších výsledků při práci.

Preparation of the brush before starting work

Before starting work, you should rinse the brush in water or thinner, which you use for thinning the paint, and rub it in your hand (or move it against a piece of sandpaper a few times). In this way, you will remove loose bristles, which would otherwise fall out during operation and stay on the painted surface. Shedding a few bristles is a natural occurrence and is not considered manufacturing defect even on a new brush.

Painting large areas

Painting large areas presents the greatest challenge. If possible, paint in horizontal position.
Painting – first, dip the brush into the coating material with the entire length of bristles and press the bristles against the can several times to achieve good saturation of the bristles with paint.

Apply the first separate brush strokes. Always start some distance from the edge to prevent the paint’s running. As the bristles dry out, increase pressure on the brush.

Smear these thick layers with strokes parallel with the first strokes alongside each other. Increase pressure on the brush. Again, change the direction of strokes – parallel to the previous direction. Now the pressure on the brush is the greatest.

In the final stage, once again change the direction – parallel with the previous strokes and even up the coat with a slight pressure on the brush.

When painting wood, make sure the last brush strokes are applied in line with the fibres.

Make sure the paint is not running down when making strokes along edges. 


After finishing work

If you wish to use your KANA painting tools in the future, you should pay attention to their cleaning and maintenance.

Generally, the best solvent for cleaning tools is the same that you use for thinning the paint. For water-based paints, it is water (best with soap or detergent) and for synthetic paints, you should use the appropriate thinner.

Keep the brushes suspended. If you keep them lying, the bristles will become damaged and you will not be able to use them again.
