A new house can be made from an old one using sandblasting. Using this method, you can create the effect of a “antique” home, or, conversely, update an old house. We will tell you how the processing is done in this article.
You can aging bricks and aging wood artificially. In order to give the house an antique look, you need to use a special abrasive mixture and a sandblasting machine. Window structures and other interior details of houses are often treated in this way. You can turn a regular wooden cabinet into antique furniture.
Peculiarities
Sandblasting is a technology that helps improve decorative attributes and does not cause too much mechanical stress on the wood. Sandblasting for wood is done using a special apparatus. It consists of a reservoir containing sand or other abrasive. There is also a unit that supplies compressed air.
There is also a hose that connects all the working components, connecting them together, there are also ball valves and a gun, the nozzle of which is made of tungsten or boron. Modern sandblasting is done on the principle of mixing air with abrasive materials, using the pressure of a gun nozzle. It has quite a lot of pressure.
Advantages and disadvantages of work
You can use the forces of nature to age. But this comes with time. Water, temperature fluctuations, and wind affect the condition of the wood. But this happens over many years. How to achieve an almost instant transformation of the surface? – Sandblasting is used for this.
It can be used to process a large surface, for example, the facade of a house, walls, ceilings, wooden beams, and complex architectural elements. There is another method of aging wood - brushing, which involves treating surfaces with special brushes, but it does not give the same effect as sandblasting.
Moreover, sandblasting technologies for wooden surfaces are more beneficial for the condition of the structure. In addition to the aging effects, they also remove old paint from wood during repairs, produce a protective mechanism by applying special compounds, and degrease surfaces.
Application area
The main area of application of sandblasting for wood is a very wide range of technical work. This includes cleaning from old coating, removing varnish or paint, getting rid of corrosion and its traces, and eliminating unplanned oil stains, and it is also used for frosting glass. Sanding wood with a fine abrasive improves its finish. The formation of even small cracks and defects is excluded, so they will not affect the result.
Reference! You can sandblast not only houses and other dwellings, but also ships and the sides of aircraft.

- Preparation before painting or protection. Cleaning wooden beams, boards or frames using sandblasting is a quick and effective processing method that allows you to remove all contaminants and macroelements from the upper layers of wood.
- We remove rot and mold. All types of biological corrosion of the upper layers of wood can be removed using abrasive materials supplied under high pressure.
- We increase the service life of a wooden product by 4 times. Due to the improved adhesion of the paint and varnish material to the surface of the wood, the shelf life of the protective suspension increases, the material does not corrode, and the wood lasts much longer.
- Artificial aging of wood. Sandblasting is used to make luxury furniture in an antique style, where the age is artificially increased due to abrasive treatment.

Types of abrasives for sandblasting a log frame
The word “abrasive” comes from the French words “grinding” and “scraping”. Consequently, it has exactly this character. Generally, abrasives can be used for polishing, honing, and sanding a wide variety of materials. For example, rocks, glass, rubber, leather, including wood.
Since ancient times, emery, pumice, emery, diamond, and quartz have been used as abrasives. Since the end of the 19th century, artificial abrasives have been used for these purposes - electrocorundum, boron carbide, monocorundum, synthetic diamond, silicon carbide and others.
Tools can be made from a wide variety of abrasive materials. These include grinding wheels, cutting wheels, and whetstones. There are abrasives in the form of tapes and even sandpaper and pastes. In general, it should be noted that the variety of abrasives is currently great and each abrasive has its own density and hardness. There is a special scale that allows you to tell how strong and hard an abrasive is. From talc to diamond - different effects and actions of abrasives are obtained.
Grinding technology
Sandblasting involves sequential performance of a number of operations. In this case, the moisture content of the wood should be no more than 25 percent. After completion of the work, the material is covered with protective compounds, the interval should not exceed 3 days. The technology consists of the following stages:
- the wood is cleaned of contaminants, foreign objects and fasteners are removed, and roofing elements are protected from the effects of the abrasive mixture;
- using a special apparatus, a sand composition is applied to the surface of the wood under high pressure, grinding is carried out in a non-contact manner, the entire surface of the log house is processed;
- the treated surface is thoroughly cleaned of wood dust and sand mixture residues;
- a high-quality primer must be used, which is applied to the base of the log house immediately after completion of the previous stages of work;
- Protective layers are applied to the wood; paints, oils, varnishes, antiseptics and other compounds are used as the main materials.
Grinding does not involve treating the ends with an abrasive mixture. This operation is performed manually. The remaining elements of the log house are subjected to abrasive processing without any restrictions.
How to select the necessary equipment and consumables
The equipment in this case is sandblasting machines. Despite their significant cost, they can bring a lot of benefits. The type of device is usually pressure, the volume of the chamber in liters may vary. Productivity is characterized by the volume of the surface being cleaned. There are quite a lot of offers even on the Internet.
Consumables are cartridges, oils, oil separators, drive belts, air and oil filters, fuel filters, maintenance kits. Equipment and materials must be selected taking into account the specific situation. You need to talk to specialists, go to the store, you can call the company and agree on everything.

Advice from LLC "AZBUKI LESA"
- The log house needs to be sanded when the moisture content of the log is no more than 15%.
It is this moisture content of the log that is considered optimal for painting and varnishing and is one of the indicators of the end of the main shrinkage. The frame needs to be coated with compounds within 3 days, so it is not advisable to order sanding of a wooden house earlier. - It is recommended to sand the walls in the log house after finishing the roofing work.
Otherwise, you will have to either very carefully cover the roof or repeat the cleaning. - After cleaning, the logs are first coated with a primer, then protective agents, glazes and oil or wax are used.
By the way, flaxseed oil has a pronounced antiseptic effect. - A good effect is obtained by applying an antiseptic
using the airless spray method. - The ends must be sanded manually;
the abrasive method does not allow these areas to be properly processed.

Features of the new technology and its differences from traditional grinding methods
Classic wood processing with a sander or grinder and jet sanding of a log frame are completely different sanding techniques.
The surface polished with a grinder becomes smooth and even.
Abrasive jet grinding involves deep processing of wood. The result is a lightly brushed surface on which the wood grain is clearly visible.
When painted, wood acquires a richer and darker shade, while the walls of a wooden house that have been sanded with a grinder look much paler when painted with the same color.
If desired, you can perform deeper brushing, as a result of which the surface becomes embossed with a clearly defined wood structure. Deep brushing technology gives the wood an exclusive and expensive look.
A log house made from logs treated with deep brushing looks especially impressive. Brushed chopped or rounded logs fit perfectly into the design of the house and bring indescribable color and originality to the interior.
