Roasting and brashirovaniye of tree are applied to obtaining effect of sostarivaniye. It is better to carry out both procedures on the street or in well aired rooms. Finishing finishing covering serves varnish.
Brashirovaniye and roasting of wood – technology of decorative finishing. Method y allow to keep the drawing of material, to give to table ancient look, to change its shade. Often technicians are used if it is necessary to issue the room in style of classics or the loft, to give to furniture vintage look.
Roasting
It is considered as the first stage of brashirovaniye. At it works are carried out concerning soft fibers of wood. Works should be carried out in the open air as in the return case it will be heavy to get rid of smoke smell.
Stages:
- To prepare blow torch or blowpipe. It is possible to use also other tool in which the flame moves under big pressure.
- To include torch, to begin to burn gradually surface. Work is carried out evenly, without delays on the same place. It will allow to burn to wood exactly without strongly burned or light sites. The necessary extent of carbonization is selected independently.
- In the course of work it is possible to come across pitch pockets and smudges. Pitch begins to burn at once. Do not allow it, at once blow off flame. Knots can demand additional treatment.
When roasting has ended, put table-top horizontally, carry out by brush with metal bristle on surface in one direction long movements. After processing it is necessary to purify sawdust. For this purpose the flat brush is useful. It is necessary to work again along fibers, but against pile. If to make differently, motes will be late in hollows.
Poskoblite table in the opposite direction. The procedure repeats until the necessary shade and the invoice appears. If to poskoblit surface a little, it will become more contrast. When using single roasting and brashirovaniye the soft structuring with smooth relief turns out. For receiving more obvious work it is possible to repeat all procedure with roasting.
Brashirovaniye
It is applied to those breeds of tree which have good structure. The sense consists in sample of soft fibers from top layer of wood surface. As a result of commission of simple actions on the place of soft layers, hollows are formed, and firm will be transformed to crests. Thanks to it the surface becomes more relief or impressive. Good stuff for structuring is the pine, fir-tree, larch, oak. It is impossible to do manipulation with beech, pear, maple or alder.
Brashirovaniye is carried out in the mechanical and chemical way. In the second case apply special structures on the processed surface. They soften material. It is necessary only to make mechanical scraping of soft layers. Most of similar structures contain ammonia, shumanit also other aggressive components. Therefore works are carried out in special protection, in well aired rooms.
The mechanical brashirovaniye is suitable for work in house conditions better. During the large works special machines are used. The sample of layers happens to use of special devices and brushes nozzles on drill. At furniture sostarivaniye the hands more often apply manual way. It will require directly table with plain surface, brush for cleaning of surfaces of old paint and bristle brush.
Process of brashirovaniye
Humidify surface before primary treatment of material. It will allow to prevent formation of wood dust in the course of work.
Following steps:
- By means of manual brush for brashirovaniye carry out material roughing. The tool moves lengthways on grain direction.
- Replace brush with polymeric nozzle with abrasive coat. With its help remove residues of soft fibers from table surface.
- Estimate quality of the carried-out work. Structuring has to meets your expectations. If it has not occurred, make brashirovaniye more distinct, having deepened grooves.
- Carry out final polish. Implementation will require sizalevy brush, abrasive paper. The last has to be with fine-grained surface. Thanks to it receive ideally smooth surface.
- Dry table and clean from dust. After that the product is ready to putting varnish. It is better to give preference parquet, it will allow to keep the gained effect long time.
How to make chemical brashirovaniye?
Use of special structures facilitates structuring process. Work will require sulphuric or hydrochloric acid, ammonia. After drawing on surface they corrode soft fibers, it is necessary to scratch out wood.
At first will move the grinding allowing to clean surface from pollution. Later put chemical means. In process it is important to watch chemical evaporation speed. If necessary the procedure is repeated. When external fibers to be softened, wash out surface of table under flowing water. For full removal of chemistry on surface pass once again brush. Then wood is dried, start covering varnish.
Use different the technician allows to gain unequal effect. When processing by metal brushes the relief of fibers will be deep and obvious. After use of method of chemical etching – smoothed.
When roasting and brashirovaniye are finished, varnishing on completely dried and cleaned tree is carried out. The material which has passed fire does not need additional toning. The Brashirovanny surface becomes noble dark shade. Sometimes in addition tables become covered by color mordants. Effectively the combination red and black looks.
