Brushes for finishing works

Brushes are common finishing tools. Soft ones are made from wool and squirrels, hard ones – from pork bristles, horse hair, synthetic fibers.


Pork bristles are naturally tapered with a bifurcation at the end, resulting in high quality coatings. However, synthetic fiber brushes are superior to natural brushes in durability..
The size and shape of the brush should be appropriate for the type of work being performed. Large brushes paint surfaces of significant size, small – narrow areas.

Wash brushes in soapy water before use..

If the hair of the flywheel brush is inconvenient (too long), the brush should be tied around the bundle with twine. To prevent stiff bristles from leaving streaks on the surface to be painted, new brushes are kept in water for an hour before use: swollen hair makes the paint smoother and falls out less often. If, after soaking, individual hairs leave stripes again, you must first work with a brush on coarse plaster, or rub it with a brush soaked in water or paint on concrete, brick.

Before starting work, a brush is developed for a more even distribution of paint along the beam: it is dipped in paint and wiped on the inner surface of the container. This operation is carried out until the entire bundle is wetted to half the length..
In the process of work, the brush must be periodically turned to ensure uniform wear of the hair bundle from all sides.

A brush is considered worn out when the hair is worn more than 60% in length. A 400 g flywheel brush can be used to finish 500-800 m2 of surfaces with oil paints without wear. When finishing with glue paints, wear is less – one brush can paint up to 1000 m2 of surface.
For a short break when working with oil paints, brushes should be immersed in water, turpentine or kept in paint. In this case, the brush should not touch the bottom of the container..
Before a long break in work, the brush must be thoroughly rinsed: the drying oil, paint and enamels are washed first in white spirit, turpentine, then in soapy water until the water stops staining.

Tied brushes are untied before washing so that the paint does not dry under the garter – this can ruin the brush. After the glue paint, the brush is washed in warm or hot water, wrung out and hung with a bunch down, giving it the shape of a torch. If the hair is loose, the brush should be lightly tied or wrapped with gauze. To avoid the appearance of fungi, it is advisable to store the dried brush in parchment paper.
