Yakisugi - Japanese wood processing technology"languishing cedar" is a Japanese technology for treating wood surfaces using fire. This simple process not only allows you to reveal the texture of the wood, but also protects it from fire, rot and insects. The service life of such wood increases to 80 years, so it is used for cladding the facades of houses and building fences.
The story began in the 18th century with the massive burning for fire protection of areas of Japanese cypress "Sugi" that densely covered Japanese villages. After some time, residents understand that burnt cypress wood is perfectly protected and amazingly beautiful; the Japanese began to widely use it in construction.

But in fact, wood burning was used by almost all nationalities, since in ancient times, along with tarring (impregnation of wood with hot resin), burning was itself a common way to protect wood from rotting. The fact is that under the influence of high temperature during pyrolysis in the outer layer of wood, the fiber channels narrow, clogging them with resins and combustion products, which significantly strengthens upper layer wood and increases its service life. In the old days, a regular fire was used to burn wood. Very often logs, floorboards and roofing boards were burned. In Rus', this process was called “smoking.”
The advantages of such wood after fire treatment:

Fire protected
- Does not rot;
- Protected from insects and fungi;
- Ease of manufacture;
- Does not change appearance and color over time;
- Service life - up to 80 years.

Nowadays, a gas burner is most often used to burn wood. To achieve the desired effect, resinous rock boards are folded into a triangular shape to form a box and then fired for 7-10 minutes. The duration of thermal exposure affects the durability of the fired board and is determined by the type of wood, its moisture content, the thickness of the board and the desired effect of structure and color. Then we extinguish the burning surface, clean the remaining ash using iron brushes and rinse running water. Ready! Now this wood can be used for cladding a facade, a route or a fence

Even though we live in an age innovative technologies, wooden housing does not lose its relevance, continuing to conquer new horizons. Popularity wooden buildings due to unique properties wood, namely its environmental safety and high wear resistance. However, due to the peculiarities of its structure, wood needs proper protection, which will extend the service life of the material while maintaining its original characteristics. Currently, it is customary to use wood for processing chemical substances, which have antiseptic and antifungal characteristics and prevent damage to lumber by insects, mold and other microorganisms, and also reduce the flammability of wood. IN Lately Supporters of environmentally friendly materials began to pay attention to another method of wood processing - roasting. Despite the fact that it is generally considered innovative, and burnt wood is a novelty in the field of finishing materials, the first mention of the use of this method dates back to XVIII century. It was then that the Japanese first told the world about the unique technology of uniform processing of wood Shou Sugi Ban, which translated into Russian means “languishing cedar.” As you know, everything new is well forgotten old, and today charred wood is again at the peak of popularity. What are the advantages of burnt wood and how to burn wood at home - we will look at it in this article.

Wood burning technology: historical background

Despite the fact that domestic craftsmen recently paid attention to burnt wood, developed countries she has been at the peak of popularity for a long time. For example, on Naosami Island (Japan) as building material burnt wood is used everywhere, and in the interior decoration of the home, products made from burnt wood, for the manufacture of which were used ancient Japanese technology“languishing cedar” Shou Sugi Ban. Processing wood in accordance with this technique allows not only to make the texture of the material more distinct, but also to protect it from insects, rotting, and fire. The history of this method of protecting wood began in the 18th century, when the Japanese, thinking about fire protection of the territory, began to burn stands of Japanese cypress (also called Japanese cedar) growing around Japanese villages. Later they noticed that the burnt cypress wood not only did not lose its original properties, but also acquired additional decorative and performance qualities, becoming resistant to fungus and insects. This is what became Starting point for the widespread use of burnt wood for facade cladding.

Despite the fact that Japan is considered the birthplace of charred wood, this method processing of lumber has been known on almost all continents since ancient times, when, along with tarring (impregnation of wood with hot resin), it was used as one of the most effective ways to protect wood from insects and rotting. This is due to the structural characteristics of the tree, which undergo some changes under the influence of open fire. Let's look at them in more detail.

Structural changes in wood under the influence of firing

The structure of wood is such that as the subcortical layers grow, pores form in it, which leads to the gradual death of fibrous cells. The increased porosity of the structure and the gradual displacement of fibers determine one of the most important performance qualities of wood - its high hygroscopicity, that is, the ability to give up and absorb water particles depending on the difference between its own humidity and humidity environment.

Another feature of wood is the unevenness of its structure. It is caused by the formation of cellulose polymers, sugars and resins during the life of wood, which are its main organic components and cause the main disadvantages of wood - flammability and the presence of a favorable environment for the proliferation of fungi and bacteria.

However, there are quite effective ways to reduce the exposure of wood to external influences. These include autoclave heating (thermolysis) and creosote cooking of wood, during which the lumber is exposed to high temperatures(up to 300-400 degrees), contributing to the destruction of unstable hemicellulose formations. They are the cause of the formation of highly flammable pyrolysis gases and, as a consequence, fire. It is almost impossible to carry out such treatment at home, but there are other, more available methods partial blockage of pores and removal of most unstable polymer formations. These include wood burning.

Why burn wood and how will this affect its performance? During the firing process, the fiber channels of wood become narrowed, as well as become clogged with resins and combustion products, which helps extend its service life.

In Rus', in order to burn wood, it was often simply thrown into the fire, which became a kind of prototype of the modern firing procedure. Often, only the lower part of the pillars, which were installed in the pits during the construction process, was fired, as well as joists and boards for the floor and roof. This phenomenon in Rus' was called “smoking.”

Benefits of charred wood

• Burnt wood can be made independently at home. To do this, it is not necessary to involve specialists; it is enough to familiarize yourself with the basic principles of firing and prepare the appropriate tools;
• Material prepared in this way acquires a high degree of fire safety, since re-ignition of wood is practically impossible;
• Due to the fact that in the process of burning wood, the destruction of cellulose components, which are a favorable breeding ground for bacteria and fungal microorganisms, occurs, its damage by insects, mold and bacterial microorganisms is practically eliminated;
• Burnt wood is characterized by a high degree of hygroscopicity.

What is the firing procedure: types of firing

Appearance and decorative value burnt wood may vary and directly depend on the technique and depth of firing. Depending on the depth of firing, there are three degrees of wood processing:

• Full firing - a type of heat treatment of wood, which makes sense to talk about if we're talking about about large-scale works. Complete burning of wood is carried out in vacuum furnaces at temperatures up to 400 degrees. Wood that has undergone a full firing procedure is used extremely rarely, since, despite its initially high strength, it not only decreases in size by almost half, but also loses its performance characteristics. However, this technique has found its application in the manufacture of furniture from burnt wood;
• Deep firing - a technology more often used for previously used lumber. Having subjected the boards and beams to deep firing, you will notice that the entire thickness of the material has warmed up qualitatively, and its surface has acquired a more expressive appearance - the shade of such wood ranges from iridescent graphite to coal-black, making it possible to imitate valuable species. Such a deep black color is almost impossible to achieve by treating wood with other methods, due to which the value of the material has increased significantly in the eyes modern designers. Deep burning of wood is carried out in open kilns, and the permissible depth of burning of the top layer of material can reach 20 mm;
• Surface firing - the most popular method of heat treatment of wood in home and industrial conditions, the essence of which is to uniformly burn the material using a blowtorch or gas burner with burning of the top layer up to 5 mm. Wood that has undergone the firing procedure is sanded, as a result of which it acquires not only its original texture, but also increased strength characteristics.

How to burn wood at home: a step-by-step guide

How to choose the right type of wood?

The first thing you need to decide on before starting work is choosing the right type of wood. The original Japanese wood burning technology Shou Sugi Ban involved the use of only cedar, but over time there was a gradual accumulation of experience in this technique, and views changed somewhat. Today it is believed that any wood is suitable to create the effect of burnt wood, however, true connoisseurs of visual delights give preference to species with the most pronounced and original texture. These varieties include soft coniferous woods - pine and spruce, characterized by a clearly defined pattern of annual rings.

Burnt beech and hornbeam wood, characterized by its increased density, will look no less original. This causes only the top layer to burn through, due to which the wood acquires original shades of gray and anthracite.

No less popular are valuable species wood - maple, alder and poplar, which, after undergoing the firing procedure, acquire the famous elongated texture, as well as larch and walnut, on the surface of which fancy textured patterns of small sizes are formed. When preparing material for the construction and finishing of a bathhouse or sauna, pay attention to birch - after firing it becomes very porous, due to which it acquires a low heat capacity and does not burn the skin when it comes into contact with it after heating.

How to prepare material for firing?

The material to be fired requires careful preparation. It is important to ensure that its surface is clean, dry and smooth, giving Special attention lack of moisture on the surface. The wood moisture content should not be higher than 13-15%, since otherwise exposure to high temperatures will lead to the formation of stripes and spots on the surface of the material, which will significantly reduce the quality of the work performed. It is also important that no traces are found on the surface of the wood. paint and varnish materials(paints or drying oils), since after firing they will take on the appearance of spots and appear unevenly on the surface. However, this largely depends on the time of exposure to fire and the depth of development of the material.

Important! The ideal material for firing is freshly processed wood that has not had time to change its color and texture. Otherwise, it will need to be sanded again.

How to burn wood with a blowtorch?

Before you start firing, you need to wait until the nozzle of the blowtorch turns red and the fire acquires a uniform purple hue.

Important! Fire yellow color cannot be used for burning wood, since the surface of the processed material in this case will be covered with soot.

In order for wood burned with a blowtorch to meet all the required standards, during its manufacture the fire must be directed perpendicular to the board and held in such a way that only the end of the torch, where the temperature is highest, comes into contact with the surface of the material. During operation, the fire is moved slowly at a uniform speed, remembering that the latter depends on the temperature of the fire and the degree of dryness of the wood. In addition, it is necessary to monitor the uniformity and contrast of the pattern. To make work easier, it is recommended to place the material being processed on stools, and 4-5 boards can be placed on them at a time, close to each other. The fired boards are nailed to the wall in the same order in which they lay on the stool during firing.

Important! In accordance with fire safety regulations, it is prohibited to burn boards nailed to the wall.

Important! If you want lumber with a contrasting pattern, consider softwood.

After you have fixed the boards to the wall, they must be covered with drying oil or nitro varnish. You can also use urea-formaldehyde varnishes.

Remember that prolonged exposure to direct sunlight reduces the contrast of wood burned with a blowtorch, and therefore is not recommended for use external cladding walls of the house located on sunny side. On average, the contrast of wood under such conditions will decrease after two months.

How to burn wood with a gas torch?

The gas burner is used only for surface firing of lumber. This is due to the fact that deeper aging of wood in fire, as a rule, is not uniform, which contributes to the uneven thickness and width of the product.

When burning wood with a gas burner, only the edge of the torch, which has a light blue tint, comes into contact with its surface. The movements in this case are similar in intensity, speed and scope to those during painting. The depth of firing during the processing of the material can be easily controlled by the degree of change in its color.

After the part has been fired, its surface is wetted using a hand sprayer. The time interval between firing and sprinkling should be the same for each section of wood, and therefore it is important to process each part consistently. After the wood has cooled, it is necessary to clean off the soot and carbon deposits formed during the firing process. To do this, use brass brushes, which will carefully remove soot without damaging the surface of the material. During the machining process, it is possible to additionally produce artificial aging wood or so-called brushing.

Important! Color solutions for furniture and finishing materials made from burnt wood are distinguished by their diversity and are realized through the use of acrylic paint. If you prefer coniferous wood, in particular pine, focus on acrylic paint colors Ivory, which is applied along the fibers.

Having produced machining material, you can begin installing the products. The structure of burnt wood does not require additional protection, but, as practice shows, protective measures do take place, and they are carried out mainly to preserve the original operational and decorative characteristics material, such as color, contrast and overall appearance. Thus, it is recommended to coat lining made of burnt wood for interior decoration with linseed or hemp oil, which is applied in several layers. Facade wood and other materials for exterior finishing covered with two layers of colorless nitrocellulose varnish with the addition of synthetic wax, which are applied using a spray gun or brush.

Important! To protect facade wood, it is necessary to use synthetic wax, in no case replacing it with natural wax, since the latter, due to its performance characteristics will not lose stickiness after processing. Before using technical varnish, it must be dissolved in turpentine heated to 40-45 degrees.

Burnt wood in the interior

The introduction of burnt wood into widespread production made it possible to solve current issues for interior and exterior design. If interior design involves the use of burnt wood to make doors, interior partitions and floors, the exterior line offers materials for the construction of pergolas, balconies, terraces and canopies. A furniture set made of burnt wood, including a table made of burnt wood and a set of chairs, together with finishing materials made of thermal wood, allows you to create a unique harmony in the area being designed.

Today, burnt wood continues to be one of the fashion trends not only in construction, but also in the furniture industry.

Modern designers have learned to use furniture made of charred wood in almost all stylistic directions with a striking aesthetic effect, and today it will become an organic complement to various design concepts, from classic to ultra-modern eclecticism.

Fire is the most dangerous enemy for wood and can quickly destroy any product made from it. It is strange to hear about the use of an open flame to process this material. With skillfully controlled firing of the surface, the characteristics of the wood are improved.

Application

Treating wood with fire emphasizes the natural structure, enhancing the contrast of the pattern, creating further immunity to rotting, ultraviolet damage, etc. In addition, such material acquires fire-resistant properties. The surface loose layer, burning, closes the channels and pores of the wood, creating damage from sunlight and wind. Protect from destruction various impregnations and antiseptics. However, such products are expensive, contain chemical additives and can be toxic. Flame processing is environmentally friendly, economical, and does not require high professional skills.

Burnt wood in the interior looks aesthetically pleasing. This is how home brushing is performed - artificial aging of products and furniture: chests of drawers, tables, chairs, panels, baguettes, boxes. You can burn the material for installing joists floor coverings, window casings, frames, doors, stairs, gazebos, technical buildings, benches, well logs, fences. If it is necessary to process complex massive structures, it is advisable to fire wooden parts before collecting structures in order to successfully carry out subsequent cleaning of hard-to-reach places. Working with prefabricated structures is risky: you may not keep track of the direction and strength of the flame, and this will lead to a fire. It is better for inexperienced craftsmen to start with small boards or products.

Wood requirements

Deciduous trees - maple, birch, beech, cherry, alder and others - cannot be treated with fire. It is advisable to burn only coniferous species: cedar, larch, spruce, pine. Their soft structure allows you to get beautiful material no stains. For decorative products, canvas of any quality is suitable: with knots, complex curves, eyes - the more impressive the result will be. Burning soft fibers form depressions, hard ones will become more prominent, after cleaning this will provide a textured contrasting surface. Wooden parts can be processed chipboards, covered with coniferous veneer. If you need burnt wood for large scale construction work, it is better to choose a higher quality one, without structural defects.

Fresh material does not need to be pre-prepared before firing: the flame will remove all roughness, replacing grinding. think about appearance will have to be done after the wood has been treated with fire. It is enough to clean off the resin stains from the lumber. If they catch fire, the entire work will be ruined. If the surface of the furniture or other product was previously covered with putty, paint or varnish, the remains are sanded to prevent unexpected ignition and to protect against stains that cannot be cleaned. Wood impregnated with stain is fired general rules. Surfaces coated cannot be treated. Old darkened wooden canvas It’s better to sand it until you get to the fresh fibers in order to get an outwardly beautiful material at the finish.

The wood for firing should not be damp. This is especially true for fresh boards. 15% is the permissible upper limit of moisture content.

Processing technology

In industry, large amounts of wood are fired in special vacuum furnaces. The thickness of the combustible layers can reach 20 mm. It is difficult to do this work at home. You can protect the material from destruction and make it beautiful using household tools.

Before starting work, you need to take care of the safety of the surrounding space and the objects in it. Firing must be done on outdoors in calm weather. Small boards can be processed on the balcony, large items should be taken outside. At the same time, it is imperative to remove paper, plywood, cardboard products, rags, textiles, and flammable materials from nearby surfaces. chemicals. It is advisable to work on a fire-resistant stone surface or metal sheet.

Suitable flame sources for firing include:

• powerful blowtorch;
• construction hair dryer;
• burner;
• gas cylinder with a special nozzle;
• Dremel.

In addition to fire and wood, you will need a tool to clean the burnt layers. If you plan to process small bars and planks, a stiff wire brush works well. Large-scale structures - large furniture, floors, stairs, buildings - are more convenient to clean with a professional grinder, grinder saw, or drill with a special attachment.

To sweep away the remains of burning, a fleitz is required - a brush with soft bristles..

All work is carried out while protecting eyes, hands and clothing from possible sparks and fumes. Place a bucket or other container with water nearby to extinguish unexpected outbreaks of fire.

We use a burner

Firing with a gas burner is most convenient. The flame should be even, calm, elongated and have a blue tint. The highest temperature required for pyrolysis is located at the top. Strong yellow fire for firing is unacceptable. For successful flame treatment, apply the flame evenly several times over the surface. The movements should resemble painting the material with a brush. It's better to start from the top. The burned board needs to burn to a depth of about 4 mm. For training, an inexperienced master can try burning unnecessary trimmings, achieving a high result.

When the surface is evenly charred, the loose burnt layer is cleaned with a prepared tool. Use a brush or sander to work along the fibers so as not to damage the structure. At the same time, they use a flute to get to deeply hidden burning particles, cleaning them out. The cleaning process is painstaking and time-consuming. This must be done carefully and carefully, removing the detached soot completely, otherwise the material will look unsightly. The quality of work is checked by wiping the wood with a napkin or soft cloth. To enhance the relief and give the wood the appearance of a real antique, repeat pyrolysis and brushing.

As a result of processing, a relief surface is obtained from dark golden to chocolate shades. If desired, an aniline-based dye is applied to the surface or immediately done finishing coat. You can use tinted primer mixtures, oil primers, nitrocellulose clear varnishes, and waxes.

Japanese way

Using this technology, only the top layer of ash is removed from the wood, the boards are washed in water, and then impregnated with tung oil, which has antiseptic and moisture-repellent properties. The processed material will acquire a noble black-silver tint and shine. Modern approach allows you to use a gas burner for convenience, although in the old days, for such purposes, wood was simply placed in a fire or oven. Firing allowed Japanese craftsmen to protect wooden structures and residential buildings from the spread of fires - the ash layer is practically impervious to the effects of fire.

The service life of burnt wood increases several times. For maintenance, it is enough to varnish or impregnate it once every 1–2 years.

Who among us does not dream of an eco-friendly home somewhere on the banks of a river, with birds chirping, and fresh air? One thing worries me - it is not durable. Sooner or later, traces of rotting will make themselves felt. Natural wood has recently become popular as a material for manufacturing and decorative items. Most often, industrially manufactured samples are treated with antibacterial, anti-mold, and fire-retardant compounds, which, alas, are not always highly environmentally friendly and safe. Is there an alternative? It turns out that everything was invented for us a long time ago - many centuries ago. The solution against aging and decay was suggested by nature itself: our ancestors noticed that burnt wood retains its natural qualities longer. We will consider in detail how to properly process wood at home, as well as the nuances of using this unusual technology in our review today.

It would seem that it could be simpler - buy varnish, process the wood and live in peace. But during use, any chemical compounds - imperceptibly, but, alas, constantly - can release a certain amount of compounds into the environment. Most often this occurs under the influence of temperatures, sunlight or. Not all Decoration Materials are equally susceptible to chemical treatment. However, the tree perfect option to use direct firing technology. How it works? During controlled heating, processes begin in the outer layer of wood that stimulate the narrowing of the fibers, and the outer “pores” of the wood are closed with resin and soot. Thanks to this, the top layer of wood becomes invulnerable to negative impact environment, exposure to bacteria, and sunlight. Plus, it really looks very nice.

Among the many ways to protect wooden products from the effects of negative factors, firing is considered the most convenient method that is easy to use at home.

Advice! Most often, gas burners are used for firing, and firing is carried out with by special means extinguishing: with a fire extinguisher and a bucket of sand. However, if you choose the right type of wood, no problems should arise.

In ancient times, no auxiliary tools not used. The necessary wood blanks were simply burned using torches, gradually turning the log over on ropes or leather straps. Sometimes it was called roasting, sometimes simmering. The most commonly used wood was cedar, beech, maple, and ash. After firing, the craftsmen removed the carbon deposits, washed the workpieces and soaked them in tung oil. During the processing process, it was important not to burn the wood, but to scorch it. If the technology was followed correctly, the result was that the wood received a unique shade, and its service life increased to 80 years.

Interesting fact! To this day, on the island of Naosami (Japan), burnt wood is used as the main building material. It is processed in a special way, the nuances of which are kept in top secret. The technique is called Shou Sugi Ban, which means “simmered cedar.” Not only houses are built from processed wood, but it is also used to make furniture and decorative elements.

Now let’s talk in more detail about heat treatment options wooden structures. The result (shade, firing depth, characteristics) depends on the type of processing and type of workpiece. Three types of firing are used for wood processing:

• Option #1. Surface firing. One of the most commonly used types of processing. It does not require much time, special training or expense. Firing is usually carried out at home using a gas torch or blowtorch. Maximum depth firing is about 5 mm.

• Option #2. Full firing. This type of wood processing is not available to everyone. The fact is that for such firing it is necessary to ensure a sufficient temperature - approximately 400 °C. This can only be achieved in special vacuum furnaces. It cannot be used en masse for processing building materials: wood loses its volume by almost half. However, this type of wood processing is popular in the piece production of furniture and decorative elements.

• Option #3. Deep firing. This type of treatment is popular for special aging of wood that has already been used. Typically this type of firing is used for decoration. The shades here depend on the exposure time - from graphite to charcoal black. Sometimes wood treated in this way can be used to construct special and garden paths. In this case, the firing depth can reach 20 mm.

Advantages and disadvantages of technology

Wood processing at home has a number of undeniable advantages:

• there is no need to use complex chemicals;
• The method, if the technology is followed, is quite simple and can be implemented outside a special workshop;
• the material acquires important properties: fire resistance, wear resistance, wood is not affected by microorganisms;
• the process can be carried out without the help of third parties.

Interesting fact! Under the influence of high temperatures, hemicellulose formations in wood are destroyed, which, when burned, form flammable pyrolysis gases. Accordingly, after heat treatment the wood becomes resistant to fire.

Is it possible to carry out the firing procedure at home?

As we mentioned above, wood processing at home is possible. However, you should adhere to certain rules and a precise algorithm for performing work. These steps depend on the type of wood and firing method. We will step by step understand all the features and nuances of the preparatory work.

How to choose the type of wood for firing

Initially, back in the old days, cedar was mainly used for firing. Over time, it was noticed that burnt beech and hornbeam wood has a similar texture and quality. The layers of wood of these two species have high density, so mainly only the top layer burns here. But the poplar or maple we are used to, after processing they get an interesting woody structure of lines elongated along the length. Conifers differ in a wide variety of patterns. After decorative processing of wood, an unusual, unique structure appears. But fire-treated birch, after firing, acquires a low heat capacity and practically does not burn the skin, which will be an additional bonus for decorating shower or shower walls in this style.

Stages of material preparation

If from the outside everything seems very simple at first glance - cut down a tree, go through it with a blowtorch and that's it - then we are in a hurry to disappoint you. First of all, you need to carefully select the material. The tree itself must be prepared for processing: remove the branches, ideally the workpieces should be dry and clean. If the wood is too wet, the evaporation of moisture can deform the surface and create unnecessary chips and cracks. Another important requirement is that if you are using old wood that has been previously used, then varnish is also necessary: ​​all unrefined chemicals will simply melt and leave an unnecessary mark, which will directly affect the quality of the finishing material.

Advice! It is best to sand the wood before processing. This will ensure uniform coloring finished product after firing and polishing.

Processing wood with a blowtorch

It is important to remember that wood processing should be carried out using the hottest tool possible. By analogy with a hair dryer (which can also be used to carry out this procedure), a blowtorch in the literal sense of the word should flare up and heat up the nozzle. For proper firing, the fire must be directed strictly perpendicular to the surface being treated. The exposure time here depends on the thickness of the workpiece itself and the goals you are pursuing. The most important thing is to carry out manipulations slowly and evenly, treating the entire surface, paying attention to changes in the structure of the material.

The surface should evenly acquire a smooth, contrasting pattern. Then the product is initially polished, as well as treated with varnish or drying oil.

Advice! If you do not heat the blowtorch to the highest possible temperature, then instead of the effect of aged wood, you will get a layer of soot.

For comfort wooden board placed on stools in several rows. Moreover, it is better to lay out the boards in the same order in which they will be installed (if it is a facade) or fastened. Processing is carried out sequentially for each.

Burning wood with a gas torch

Unlike a blowtorch, processing with a gas torch has a number of nuances. It is most often used for surface treatment of wood. This is due to the fact that the flame of a gas burner penetrates more deeply into the structure of the wood: with increasing exposure time, it will not be possible to achieve uniformity.

The most important thing is to strictly control your own movements so as not to overexpose the flame in one area to the detriment of another.

The technology requires mandatory wetting of the wood after firing. Moreover, the period of time between firing and spraying from a spray gun should be the same. After cooling, the top layer is cleaned and the soot is removed either with a stiff brush or with a special brass wire.

Does burnt wood need additional protection?

Burnt wood itself has a number of undeniable advantages, but it also needs protection. Most often, after the first stage of cleaning, the product is treated with oil. Usually after this a protective varnish is applied. And if the coating will be used to decorate the facade, use synthetic wax dissolved in turpentine. This will allow the wax to acquire additional bonding and protective properties.

Where is treated wood used?

Burnt wood has recently become very popular among designers. You can buy interesting interior items made from burnt wood in art workshops or studios of modern designers.

The effect of using burnt wood in the interior

Wood is widely used to create furniture. It doesn’t matter whether it’s a flat board or untreated wood: in any case you will get unique item furniture created with love, as well as wines, household utensils.

Sometimes even entire areas are finished with such panels. For example, a kitchen or bedroom.

The nuances of using burnt wood in the design of facades

Burnt wood is used quite often. It gives the building a unique chic. If you think this makes the room look old, you are wrong! The design of facades can be quite avant-garde.

The possibilities for using burnt boards are wide. The treated wood shows very good “driving performance”; it is widely used both for facade finishing buildings and for interior decoration. The process itself, as we found out, is not so complicated, and the result is truly impressive.
