Do-it-yourself grinding of rounded logs should take place according to the developed technology, in accordance with specific rules and obligations.
Suitable period for polishing
During the production of rounded logs, the wood remains naturally moist. Uncured wood is not intended for sanding, as such work will cause even more “shaking”. best time for processing is considered 10-12 month after completion of construction log house, before cladding.
The grinding of logs is carried out on an already blocked building. Otherwise, further finishing will not be effective enough. If over the past year the logs are covered with a dark coating, then they need to be painted with a special antiseptic with a whitening effect. Processing begins only after the wood sheet has dried.
After grinding, it is necessary to treat the canvas with a disinfectant or paintwork composition, otherwise the tree will darken again, and all actions will be wasted.
An equivalent shade of the log house can be obtained if the finish is completed a maximum of four days after the end of the grinding activities.
Sanding tools
Modern construction market offers many devices for self-grinding rounded logs, but not all of them are able to cope with the task at the proper level.
The equipment used in the work must be powerful enough, but at the same time not too heavy.
Belt sanders work well with flat wood material, but not suitable for semi-circular logs.
It is better to take a grinder with a special grinding nozzle, which looks like a disk with a fixed sandpaper, shaped like petals. Its power must be at least 0.85 kW. It is most convenient to use 12.5 cm wide discs, although other models can be selected. Hard-to-reach places are recommended to be processed with a chisel.
For the initial, rough processing, petal sanding discs with a coarse grain (40-60) or a simple abrasive are taken. It should be borne in mind that the discs will have to be changed often: every 3-5 meters. The number of fine grinding discs (100-200 mm) depends on the quality of the initial processing. It is better if they are Velcro, so they can be replaced faster.
Thus, to perform high-quality grinding of logs, you will need:
- Eccentric sander;
- Bulgarian with sandpaper;
- Chisel.
Grinding works cause a lot of dust, so it is worth preparing personal protective equipment.
All equipment must be manufactured by trusted manufacturers to ensure its reliability and durability.
Grinding order
Grinding logs is considered a time-consuming and important process, so it is recommended to follow all its stages:
- Work begins with the removal of the top wood layer. To do this, you need to take a nozzle with fixed sandpaper with grains No. 160-40. Such processing will end with the formation of a pile.
- Next, finishing is carried out using a nozzle with grain No. 10-8, which removes the pile that has appeared from the wood.
- At the last stage, final grinding with grains No. 6-M63 is performed.
Hard-to-reach areas are best treated with thin plastic nozzles, characterized by affordable cost and durability. It is most difficult to grind the joints of logs at the corners of the building. Here you can use a chisel with a cutting piece 2 cm wide.
Grinding rounded logs should be done slowly, in the longitudinal direction relative to the wood threads. At the same time, do not press too hard on the grinding tool - the work should go as smoothly as possible.
End element processing
The ends are the areas with the greatest exposure to negative external influences. They absorb moisture the fastest, they account for the maximum expenditure. paint and varnish compositions. In this regard, the ends of the house require a careful approach to grinding.
Our ancestors used a blowtorch and a hammer for processing. The firing of the ends increased their service life, but negatively affected appearance. Hammering was aimed at better connecting the fibers and blocking the passages that take on atmospheric moisture. Such manipulations made the wood sheet hard and “mirror-like”.
Today, several nozzles are used to grind the ends. Work starts with number 160 and ends with number 10. Compliance with all technological requirements allows to reduce the absorption of moisture, paint, varnishes and increase the time of operation of the log structure.
Grinding a rounded log with your own hands will go “smoothly” if you heed the advice of professionals:
- You should not turn on the grinder at too high a speed: this will create deep grooves in the log.
- Grinding the resin surface causes it to rub and blocks the removal procedure.
- Places of radial wood must be treated with glue and wait for it to dry.
- Usage paintwork materials on the water based during the initial staining, it may result in raising the pile. Re-sanding will help correct the situation.
- Processing of rounded logs must be done before the installation of doors and windows.
Grinding log cabin perfect for any homeowner. But remember that it will take a lot of time and effort.
There are no trifles in construction. Quality grinding wooden house no less important than a neat finish. Alpinia-Wood craftsmen work with logs, timber and other lumber.
The cost of sanding a wooden house depends on the following factors:
- number of passes (usually masters work in 1 or 2 passes);
- scope of work (when processing walls, the price of polishing a wooden house is calculated per sq. m, when processing ends - per m. p.);
- surface type - rounded log or profiled timber (in the latter case, the price of polishing a wooden house is slightly lower due to the relative simplicity of the form).
Purpose
Sanding the walls of a wooden house is a mandatory step before applying paint or varnish. At proper preparation The coating lays on the surface in a perfectly even layer, does not crack over time. In the regions middle lane, for example in Moscow, grinding a wooden house is an excellent remedy against blue stain and other fungal infections.
Sanding a wooden house inside differs little from the same work on the facade. The work includes the following steps:
- preparation - cleaning surfaces from dirt and drying (working on a wet beam can lead to deformation);
- rough processing - removal of pronounced irregularities with an abrasive with large grains;
- basic processing - elimination of less significant defects with an abrasive with a fine grain fraction;
- finishing- an optional step recommended for preparing walls for varnishing.
The grooves are processed with a grinder or grinder, the corners with a chisel. After each stage, the surface is cleaned of dust with a vacuum cleaner.
At the end, the wall is treated with antiseptics. Grinding a wooden house from the outside is carried out shortly before applying protective compounds, otherwise new irregularities and damage may appear on the surface. At internal works ah, it is advisable to apply the impregnation in the next 7 days. When finishing the bath, it is important to use not only antiseptics and fire retardants, but also moisture-proof compounds.

Building a beautiful wooden house is the pinnacle of art. Naturally, the polishing of the log house plays a significant role here. However, it must be done carefully and correctly. Otherwise, you can just spoil the material.
What is the procedure for?
Sanding a log house is necessary to clean wood from mold or fungal diseases, as well as various kinds of damage. In addition, treated logs absorb various varnishes or antiseptic impregnations better. And this procedure is also needed to improve the appearance of the log house. The fact is that it becomes smoother, more aesthetic.
Chisels.

Tape machine.
Fine processing. For this purpose, a skin with fine grain is used - 150-180.
Final polishing. it final stage. For the final processing of the log house, you will need material with the finest grain - 220-240.
Grinding a log house, the technology you already know, will make your home more comfortable, beautiful and strong. After completing this procedure, it is necessary to treat the wood with an antiseptic composition. After it dries, polish the surface of the log house with a colorless or colored varnish. That's all the features of the work. Good luck!
Modern approach to wooden construction- use of rounded logs. The material has precise dimensions and a cleanly rounded shape, which allows the construction of a log house without a large number waste that appears in the process of fitting logs to each other. But regardless of this, it is necessary to carry out a number of works related to the protection of wood, where the polishing of rounded logs occupies a special place.
Log house sanding
The main purpose of polishing a log house is to give the wooden building an attractive appearance and remove upper layer wood that is contaminated with microorganisms. After the construction of a wooden house made of logs, it is not recommended to drive into it and live immediately. During the year, the house undergoes natural shrinkage, after which you can think about how and by what means to carry out the decoration.
More often than not, various protective impregnations, which not only protect the tree from the negative effects of microorganisms, but also emphasize the structure of the material. Therefore, the polishing of rounded logs must be approached responsibly, especially since this work is considered difficult.
Grinding rules
Like all construction processes, the polishing of a log house is divided into several stages.
Stage number 1 - preparatory
At this stage, you need to prepare the tools. The market today offers a fairly wide choice, where in the first place is Sander tape type. But there is one point that inexperienced masters may not know about. If the house is built from a bar, that is, a material with flat edges, then a grinder - best option. For processing logs with rounded edges, this tool is not suitable. In this case, it is better to use an angle grinder and special Osborne brushes.

Osborn brushes
The bristles of the brushes are made of nylon impregnated with silicon carbide. The material is wear-resistant, one tool is enough to clean 250-350 m². It is necessary to work with them at low speeds - up to 3500 rpm. It is not recommended to increase the speed. Reasons - the wood begins to burn and the ends of the pile melt.
For grinding logs or timber use different brands brushes:
- P46 - rough cleaning and brushing.
- P60 - intermediate grinding.
- P80 - finishing.
- P120 - finishing.
The ease of use of Osborne brushes lies in the fact that with this tool you can get to hard-to-reach areas. In addition, we note the minimum amount of dust emitted during processing. Watch a video on how Osborne brushes are used when sanding a log house.
grinder with grinding discs
To carry out this type of work, the grinder is often used. The main thing is to choose the right power for it. An 850 watt instrument is perfect. Pay attention to the weight of the grinder, because grinding the log house is a lengthy process. A heavy unit will not allow you to use it for a long time (hands will “fall off”).
With regards to grinding wheels. The grinding process consists of four steps:
- Rough processing. Here you need a disk with large grains - No. 40.
- Fine-tuning. A tool number 80 or 100 is used. The task of the stage is to smooth out bumps and protruding pile.
- Fine grinding. Sandpaper number 150-180 is used.
- A finishing treatment that achieves perfect smoothness. Tool #220-240.
Please note that up to three discs are consumed per 1 m² of sanded surface, so you will have to stock up on a large number of them. When doing work with a grinder, it should be noted that this process is dusty. Therefore, it is necessary to take care of safety measures: glasses, gloves, a respirator.

Sandblasting technology
This is an innovative way of processing log cabins from logs and timber, which differs from the two previous ones. high quality ongoing work. The technology is based on an abrasive mixture of different types sand, which is applied to wooden surfaces under pressure.
The only negative is the availability of special sandblasting equipment, which costs a lot of money. The method requires the presence of a qualified foreman who has previously been trained.
Additional advantages of technology:
- The speed of the process. It is four times faster than working with a grinder or angle grinder.
- Uniform grinding of any sites, even hard-to-reach.
- On the wooden surface there are no traces of abrasive, which sometimes happens when using a grinder and grinding discs.
- In this way, infected areas and rotten ones are polished, bringing them to an ideal state.
- If the log house was painted or varnished from the inside, then the abrasive mixture easily removes the coating.

Stage number 2 - the main
The process of polishing a log house requires patience from the manufacturer. There is a certain sequence that cannot be changed. Several useful tips from professionals:
- It is impossible to grind logs that have dried out badly. Wet wood is almost impossible to process. Its fibers are lifted up, the structure is lubricated. So there is no need to talk about a presentable appearance.
- The work is done from top to bottom.
- There will be a lot of dust when grinding logs with a grinder. Therefore, after finishing the grinding of the walls of the house, it is necessary to sweep with a broom or vacuum.
- Work is carried out before installing windows and doors, assembling the ceiling and floor. But the roof must be erected.
- The surfaces of the walls are divided into sections - grips. They are sanded one by one. This also applies to the external surfaces of the walls of the log house, and internal.
- Hard-to-reach places - the junction of logs in the corners of the building. Here the power tool will be useless. Therefore, the work will have to be done manually using a chisel. Better blade width - 20 mm. It is not worth actively diving into hard-to-reach places. A small removed layer is the optimal solution.
- Before using a newly installed disc, it is recommended to grind it a little to remove large protruding grains. Turning is best done at the ends of the logs, which form openings in the wall. Subsequently, they are closed with boxes of windows or doors, so that this will not affect the appearance of the log house.
- It is recommended to move the grinder not with the hands, but with the shoulder girdle. This will create a smooth movement of the tool, due to which differences in the plane will not form on the surface of the sanded logs. Plus - such work will not let a person get tired quickly.
The sequence of work carried out is as follows. First, the main planes of the logs are ground, then the ends, and lastly the grooves. With the processing of grooves you need to be careful. The grinder disc can get stuck in them, and this can lead to pulling the power tool out of your hands. So attention and only attention. In this regard, the Osborne grinder and brushes are safer, not to mention sandblasting technology.

Treatment of the log house with protective compounds
Wood is a soft and fibrous material. Humidity and microorganisms in a few years turn it into an unusable material, therefore, after grinding logs and beams, it is necessary to cover their surfaces with antiseptic and flame retardant compounds. The former are responsible for the safety of lumber from negative impact mold and fungus, the latter increase fire resistance.
Protective liquids are applied with conventional painting tools: brushes and rollers. If the treatment area is large, then a spray gun is used. First of all, an antiseptic is applied, after it has dried and absorbed into the wood, a fire retardant is applied.
There is another composition that gives the tree certain shades. It is called glazing material. There are more than 40 varieties of glazing compounds on the market today, which give wooden walls different shades, there are also colorless options among them.
It should be noted that protective liquid materials are divided into two categories: for internal work and external. They cannot be interchanged, because for external use the compounds are very toxic, although they have higher protective properties.

Conclusion
Grinding wooden walls a log house erected from logs or beams, a mandatory procedure that gives the building a presentable appearance. In this case, a small layer of wood is removed, often infected with harmful microorganisms and rot. That is, the walls of a wooden house are “healed”, due to which the service life of the entire structure is increased.
A mandatory procedure that must be performed after the installation of the log house is the grinding of logs. These works are preparatory stage for finishing walls and help to level the surface of the tree, remove defects, mold and putrefactive formations from it. Processing improves the adhesion of walls with antiseptic and coloring compounds, and also helps to reduce the consumption of the latter. When applying solutions on an unprepared plane, the impregnation of wood is of poor quality and unevenly.
In addition, during the manufacture of rounded logs, due to overheating of the cutting edges and a violation of the sawing technology, polished areas may form on the surface of the tree. Such places are poorly impregnated with protective compounds, therefore, subsequently in more subject to damage.
When sanding, the defective layer is removed and the natural properties of the wood are restored. It is advisable to start grinding the log house immediately after the completion of the main construction works, without waiting for the final shrinkage and shrinkage of the tree, since smooth, even logs better withstand the impact environment and penetration of harmful insects.
Required Tools
Grinding a log house can be carried out with the help of a specialized organization or independently. The process consists of several simple operations, the implementation of which, however, requires a certain skill and accuracy. The set of mandatory tools used by the performers of the work is as follows:
- eccentric grinder;
- grinder with emery nozzles;
- belt type grinding machine;
- chisel;
- individual protection means.
The belt type grinder provides maximum performance, however, in the absence of experience in using this tool, there is a high probability of marriage. The eccentric machine allows you to grind logs, leveling the pressing force, which prevents the formation of accidental depressions and bumps. Bulgarian is used for grinding grooves between logs, and hard-to-reach places corner joints are processed manually with a chisel 20 mm wide.
Execution of work
Grinding a log house is a labor-intensive process, and its technology has various variations. Part experienced craftsmen believes that in order to polish the log house, you need to wait for the end of shrinkage, while others clean up as the walls are erected in order to avoid damage to them. For acceptance right decision quality must be taken into account. building material. Rounded log with applied in the factory protective coating can withstand 1-2 years without noticeable damage, but after this time it will take much more effort to process it.
The main work on the facade and the inner surface of the walls of the log house is recommended to be performed using an eccentric grinder. Depending on the number of builders, the common plane must be divided into sections on the basis that in one day the contractor polishes from 6 to 8 square meters. It should be borne in mind that the area should not be left unpainted for more than 3-4 days, as the material will darken and the cleaning will have to be repeated.
On the grinder a plastic flat nozzle is installed. Rubber options are not suitable for wooden surfaces round shape, because they quickly become unusable. The work is carried out in two passes:
1. First, it is necessary to grind the rounded log with coarse sandpaper (No. 40). With the help of this abrasive, the top layer of wood is removed, all defects, fungal and mold damage are eliminated;
2. final cleaning is done with emery fine fraction(No. 100). In this case, alignment occurs and the wood pile raised during the primary grinding is removed. The surface should be smooth and pleasant to the touch.
After finishing the grinding of the main surface of the site, it is necessary to refine the grooves and corner joints of the log house. You can grind the grooves between the logs with a grinder with a plastic nozzle. For safety reasons, its diameter should be slightly smaller than sandpaper. Otherwise, there is a danger of injury when the nozzle is jammed between the logs and the grinder is pulled out of the hands. Corner connections log structures can only be cleaned manually using a chisel. The ends of the logs are polished with a grinder or a belt-type machine.
The most common mistake made when processing wooden cottage or polishing a bath from a log with your own hands, is the wrong choice of tool, which is associated with the desire to speed up the routine process. Too powerful grinder, operating at high speeds, the structure is easily damaged. If you awkwardly press the handle or change the angle of the nozzle, a deep recess will remain on the surface, which can no longer be removed. Practice shows that the optimal power of the grinder should be 700-800 watts.
Grinding a house from rounded logs involves the formation of a large amount of dust, so work must be done with by individual means protection. It is recommended to use transparent goggles with side shields, a respirator mask, headgear and gloves. Shoes should be comfortable and durable. It is possible to grind sections of walls at a height using professional inventory scaffolding or high-quality scaffolds made on site.
Application of antiseptics
To protect against fungus, prevent the development of mold and damage to wood by insects, the rounded log must be treated with antiseptics. They increase the durability of wood building structures and help reduce repair costs. further exploitation log house. In order to choose the right solution, take into account the following:
1. the cost of a quality composition is quite high, but since we are talking about long-term investments, it is impossible to save on this;
2. you should purchase an antiseptic in specialized construction stores or supermarkets, as this reduces the risk of buying low-quality goods (the latter, in addition to its uselessness, can also turn out to be toxic);
3. when buying a product, you yourself need to make sure of the guarantee of protection against all types of biological effects;
4. the composition for the outer walls of the building should not be washed out by precipitation from the pores of the wood;
5. in order to preserve the protective properties of the log, the log house after impregnation with an antiseptic must have top coat.
Primary impregnation is carried out immediately after the logs have been sanded. In this condition wooden structures can last up to a year. If shrinkage continues, after this period, intermediate impregnation of the log house with an antiseptic is performed. Finishing and finishing coating are made after the wood has completely dried and stabilized geometric parameters building.
The impregnation process can be carried out manually with a brush or mechanized way using pressure sprayers. The first method is more laborious, but allows you to achieve best result. The main quality criterion is to cover the entire area of the walls of the log house with an antiseptic in two layers. For easy tracking of missed segments in protective compound coloring pigment is added.
The cost of polishing a log house by specialized organizations depends on technical condition logs, the standing time of structures, as well as the region where the cottage was built. Average grind 1 square meter the walls of a log house cost 200-300 rubles, and in Moscow and the region the price is the lowest due to the great competition among the performers.
