  • Use the proper brush according to the need
Currently there are available variety of brushes in many types and models, each having its own function and will produce different results. The type of brush used in a finishing process must match with the finishing materials used and the desired effect. For example, the applications  of glaze that need an even layer requires flexible brush type with a thick tip. The thick brush is also ideal for clear coat application which needs to coat material evenly and smoothly. Meanwhile for texture application a stiff and stronger brush is required.
The size of brushes that are used must also according to the board size of the surface  being coated. The wide brush is inefficient for coating to the small surface and too small brushes will need too much repetition of strokes that result in waste of material, time and energy.

  •   Caring of the brush.
As well with other tools, brushes also need a good maintenance to remain them always in good condition. We need to make sure that the brushes are ready every time they are needed. The bad condition brush will not be able to give optimal results. A dirty brush should be washed and cleaned before it used, while the damaged brushed should not be used again. The uses of bad brush will only result in wasting time, energy and finishing material.
Brush is maintained by always be cleaned immediately after it used.  The finishing material that has been dry, harden and stick to the brush will be difficult to be cleaned without damaging the brush. Soon after the work is completed dip the brush into the thinner and clean the dirt by hand or cloth. Then dry  the brush with clean cloth or blow the brush with compressed air until it dry. Store the dry and clean brush in its place. Brush can also be dried and stored by hanging to let its liquid inside drip and dry.
Use the appropriate thinner according to the finishing materials used. Brush for water based paint application can be immersed and washed with water; warm water will help to speed up dissolution and cleaning process. Brush to apply the  glaze oil or wax can be cleaned using mineral spirits or turpentine. While the brush for lacquer or varnish applications requires lacquer thinner or acetone to dissolve and clean its finishing material.
Brush should not be immersed in a fluid or paint thinner in a long time. The wet brush should be immediately cleaned, hung or dried and stored in a dry state.
