Grinding the beam with your own hands outside. Features of grinding of profiled and glued beams

Grinding logging. pros and cons of log cabins, grinding features, nuances and stages of technology, error, finish processing

Give maximum evenness and the best aesthetic qualities of the surface of the wood, as well as perfectly prepare it to protect against external factors, a special grinding of log cabins allows. We will analyze what are the main advantages, cons and features of the operation of a wooden log house, which gives the procedure and when it is best to start, which is the differences in the technology in relation to the log and different types of beams, what stages the technology consists of, what are possible errors, and also performed as it is performed Protective finish processing.

Wood log house is a design of the sequential rows of logs or timber. They are attached to each other in the corners of a special castle system. cuts in the material. In this case, the crowns are fastened with the help of thorns inserts into pre.drilled holes.

The use of this kind of housing construction technology has the following number of advantages:

• Absolute harmlessness. Wood is a natural environmentally friendly material that does not distinguish even allergens. over, at room temperature, aromatic substances beneficial for health are received in the air of rooms.
• Healthy microclimate. The porosity and ability to absorb and give moisture to the material create a stable moisture indicator in the room.
• Good gas exchange. If you initially correctly fabricate the log, cleaning from the outer layers, the room will not be clogged, as is the case in buildings of brick, stone or concrete. On the contrary, the high porosity of the material contributes to the rapid refreshing of the internal atmosphere, but without significant heat loss.

• Natural thermal insulation. With sufficient thickness, the beam or log hold heat well even during severe frosts.
• Resistance to loads. The tree enclosed in the shape of a log house is very resistant to various kinds of deformations, including soil shifts. Therefore, the home does not need to build an ultra.duty foundation, as, for example, this is required for a brick building.
• Soundproofing. With sufficient thickness, the walls absorb internal sounds and do not allow external noise to penetrate.

However, no matter how perfect the wooden log house seem to be ideal, sooner or later it will begin to show the following shortcomings during operation:

• Darkening, pollution and as a result of the loss of natural texture and shade, and, consequently, the initial aesthetic qualities.
• The destruction and aging of wood as a result of the development of natural biological processes. the formation of fungi, rot, mold, insect colonies.
• Deformation, cracking as a result of the effects of natural factors. heat, cold, damp, drought, rain, snow, frost.
• High probability of fire. due to the exposure of dry wood with easy ignition.

It is possible to avoid ultra.fast destruction if you grind a log house from logs or a beam in a timely manner, and then apply special protective compositions to the surface.

Features of the grinding procedure

Properly made grinding gives the following benefit to a wooden house:

• Improving aesthetic qualities. Mechanical processing leads to alignment of the surface and elimination of protrusions, as well as minor defects. cracks, chips, roughnesses. This gives the tree a natural color and texture.
• Strengthening surface adhesion. In the future, this will improve the depth of impregnation with special means, and, therefore, will increase the protection of wood from external factors.

• Prevention of premature aging. A flat wood surface protected by impregnation is little or not at all exposed to dampness, heat, frost and atmospheric precipitation.
• Reduction in the consumption of funds for the finish coating. Due to the evenness and lack of protrusions, the surface area becomes smaller, and therefore a minimum of paints and varnishes for the final finish will require.
• Exclusion of the development conditions of rot, mold and fungi. Grinding logs of the log house and ends, followed by antiseptic impregnation, almost completely eliminates the possibility of developing pathogenic microflora on the walls during the entire period of operation of the building.

In this case, it is necessary to start the grinding procedure only if the following conditions are met:

• The wood has completely dried up and gave the main shrinkage.
• The roof is completely installed so that the walls are not undergoing from rain.
• The degree of moisture in the material does not exceed 20%.

When processing a fresh log house, that is, when the wood is not dry enough, the tool will constantly clog, and the surface is “shaken”. over, if a specialist still succeeds in qualitatively performed the procedure even under such conditions, a raw tree cannot be treated with an antiseptic and other compositions.

Since this will clog raw material from the outside, as a result of which it will begin to rot from the inside. If you leave it to natural drying, the wood will quickly darken and lose its aesthetic qualities. At the time of application of the coating, it will need to be sanded again. Therefore, grinding is better after shrinkage.

When you can start grinding the log house

Traditionally, grinding of a log or timber house is made after its shrinkage has passed, and the wood is completely dried. This process usually takes at least a year, and in some cases it proceeds and longer. It all depends on the quality of lumber, breed and moisture level of wood. The climatic features of the terrain play an important role.

A house from a profiled timber, which is usually made of freshly sawed forest, passes a shrinkage and dries in about ten to twelve months. Glued beam has a low humidity, so grinding can be done immediately after construction.

The external grinding of the log house is not recommended in winter at minus temperatures. The polished tree must be treated with antiseptics to protect from the sun and precipitation, and this can only be done in the warm season. At the same time, grinding from the inside of the house can also be performed in winter, provided that the plus temperature remains in the interior.

The need to grind the log house outside

During the shrinkage, the log house, while on the street, is influenced by rain, snow, wind, solar radiation. As a result, a wooden house loses its attractive appearance, logs darken, covered with a blue raid, from excess humidity the wood begins to rot, mold appears.

Grinding stops the development of negative processes and allows you to restore the original type of wood. In addition, the grinding performs the following tasks:

• Removes irregularities and gives the surface smoothness, which contributes to a more attractive type of walls and a smaller consumption of paints and varnishes;
• improves the absorption of protective equipment, which increases the life of the wood;
• eliminates the surface of small knots and other defects;
• removes blue, as well as areas damaged by the fungus and mold;
• helps to increase the life of a wooden structure.

Often home masters, wondering: why grind the log house before painting, begin to stain logs, missing the grinding stage. As a result, after some time, the coating begins to crack and glance, which, in principle, is not surprising. Grinding provides good grip of paintwork with wood and deep penetration of paint into the structure of wood. Thanks to this, the wooden surface receives the necessary level of protection and the service life of the coating increases.

Surgery icing

Coniferous rocks, as you know, contain a large number of natural resins. On the one hand, this circumstance is an advantage, since resinity protects the tree from decay and mold formation. But on the other hand, the resin prevents a good clutch of paint with a tree, and when grinding, it is spread over the surface and spoils the type of wood. Therefore, before processing the needles of the corner grinder, it is necessary to remove the excess resin.

How to remove tar from a log before grinding? Solvents are suitable for this: acetone, white spite, turpentine, purified gasoline. You just need to apply the selected remedy to the wooden surface, and wash off the residues with warm water.

How to grind a log house from chopped logs of corner grind

The corner grinder is the main tool used to process the log house of chopped logs, the surface of which contains the remains of the bark, knots, cracks and other defects.

• For primary rough processing, use:

• special grinding and polishing circles;
• cordless cords with wire pile;
• Universal foundations, to which interchangeable sandpaper nozzles with large grain 0-60 are attached.

The corner grinder with these nozzles copes with the uneven surface of the log cabin logs. As a result of primary processing, more or less large defects and protruding parts are removed from the surface.

• To clean up logs with an old paintwork, pendant nozzles in the form of a bowl with twisted wires are best suited.
• The next stage after draft processing is a thin grinding, the purpose of which is to completely level the base and prepare the surface for painting or varnishing. It is performed with grinding circles with fine-grained nozzles 0-120.
• If logging logs is provided, this operation is best done using fabric nozzles.

It is not recommended to grind immediately throughout the area. It is advisable to process the surface in parts, dividing the wall into certain zones. In this case, grinding performance will be higher than when processing large areas.

Rules and techniques of grinding

The process of grinding the log house is simple. It can be performed with your own hands, and if you have the necessary tool, even a novice carpenter will cope with it.

A grinding machine will definitely be required. Depending on which log house you have to be grinded, it will be necessary to use either an angular grinder (angular grinder) or a strip or vibration grinding machine. In addition, you need discs and circles. Again, for each type of log house and for each type of grinder, its consumables will be required.

note! When choosing a grinder, you need to pay attention to its power. It should be no more than 1000 watts.

There is still such a relatively new tool for grinding a log house as a nylon brush. It allows you to better highlight the texture of the tree, leave more wood, without washing excess. You can use it in the same way as a corner grinder.

The use of corner grinders

For grinding a log house made of logs, especially natural, it is better to use a corner grinder. Disks with wire hairs, similar to a round brush are used as consumables. Another option is a petal circle with segments of grinding paper. With such disks and circles, grinding is carried out very quickly, but roughly. It is convenient to use them when it is necessary to remove the old worn.out coating. The speed of the disk rotation must be selected small-about 8-10 thousand revolutions per minute. The same tool can be carried out primary grinding and a shrub.

For more thin grinding, special nozzles are used, to which round discs from grinding paper are attached. The reverse side of the paper is covered with pile, and the nozzles have many nylon hooks in their design. The grinding disk is simply applied to the nozzle and fixed according to the principle of clothing fastener of Velcro. Primary grinding can be done with discs with a granularity of 40-60, finish grinding is carried out by discs 80-100. The number shows how many abrasive grains are per square centimeter. Obviously, the larger this number, the thinner the grinding and a more smooth surface will be.

The use of vibration grinds

Near the joints of the logs, grinding corner grinding is unsafe, since the disk that fell into the joint can “bite”. Another unfavorable factor is the presence of a jute or moss gasket between the crowns. If the brush disk is hooked for this gasket, the corner grinder can easily be pulled out of the hands. Under these conditions, it is better to use a vibration grinding machine.

If the cutting of the log house was carried out with the remainder, that is, the ends of the logs protrude beyond the outer fishing line for the trimmer of the log house, internal corners are formed, which are very difficult to process. In this case, the use of vibration grinder with a working surface in the form of an iron may help out. The sharp angle of such a machine can be reached even in the most inaccessible places. If this does not help, the internal angles at the intersections of the logs can be treated with a chisel.

Very often, when profiling at the corners of the long faces of the beam, a chamfer is produced, that is, the angle is slightly cut. This is done in order to give the beam a more interesting look and prevent rainwater flowing down the wall, in the joint between the crowns. For processing such a chamfer, it is also best to use a vibration grinding machine.

Work with a tape machine

A log cabin of a beam can be polished with tape grind. In this case, it is necessary to ensure that the direction of movement of the tape coincides with the direction of the fibers of the timber. Otherwise, transverse scratches will appear on the surface, which will give the surface a not very attractive look.

Bleaching

It often happens that the login of the log house is affected by mold fungi. After grinding, the surface becomes smooth, but individual sections acquire a gray or blue tint. On dry wood, it can be barely visible.

If such a surface is wetted, then black and blue spots are very distinct, spoiling the view of the log house. The same thing will happen during the application of the protective coating. To avoid this, special products are used. whitening for wood.

These compounds contain, as a rule, chlorine.containing substances. They processed the affected areas of the surface, dried, and after that the grinding is repeated. Typically, one or two applications of the bleach is enough for the wood to take on the former.

Security measures and protective equipment

The grinding of a log house is accompanied by a large amount of wood dust, to which molds from affected areas may also be mixed with. Inhalation of such dust is very harmful to the human body, so the work must be carried out in the respirator. Some models of grinding machines are equipped with special bends to attach them to vacuum cleaners. This is very convenient, as it allows you to immediately remove dust from the place of grinding. Protective glasses are necessarily used to protect the eyes.

Employees’ hands must be protected with dense gloves of rubber, tarpaulin or sawing. It is not allowed to use knitted or woven gloves, since during operation they can catch on a grinding circle or tape of a grinding machine. In this case, injury is inevitable. When working with a vibration grinding machine, you can use special gloves with a vibrating effect.

With proper performance, grinding will help to return the log house a great appearance, and subsequent processing will save it for many years.

Dry and wet grinding

For grinding wood, before applying finishing coatings and after them, two relevant techniques are used. dry and wet.

Dry grinding increases the effectiveness of the abrasive and makes it possible to use it more carefully. At the stages of intermediate grinding of delicate finishing materials, this is what needs. The disadvantage of this technique is that the skin is quickly clogged with garbage. To eliminate this problem, experts advise using an emery canvas with omnipotent properties.

Wet grinding involves applying liquid to the granular surface of the sandpaper. The role of such a working fluid can act as an ordinary soap solution, white spiteity and mineral oil.

The abrasive with wet grinding is clogged much more slowly and, accordingly, its service life increases. But the wet method also involves the formation of unpleasant mess from chips and foam. The home master in this case will have to periodically wipe the wooden product.

Rules of manual grinding

You should start grinding with your own hands with the largest.grained sandpaper from those available in stock to eliminate obvious defects from the surface of the tree. But here it is necessary to take into account the nature of the damage that you need to get rid of.

note! If the defects on the surface are minimal, then it makes no sense to start with an abrasive P40 (this abrasive is suitable only for very large tubercles and depressions).

You need to act on the surface correctly: it is best to move the block or just sandpaper in a straight line along the fibers in the direction of the back. And grinding, for example, in circular movements can lead to the appearance of extra scratches.

Having reached the edge of the processed surface, sharp corners should be stuck. Soon, as a result of the effects of the coarse.grained abrasive, the dust of dust will begin to appear on the tree. They should be carefully removed by a vacuum cleaner. Next, you can proceed to processing the following sandpaper with medium granularity.

This processing is carried out according to the same principles that were described above. The final stage is a grinding with an abrasive with the smallest grain. After that, a wooden product should become completely even, no flaws should remain on it.

Tools and equipment

For rough and final grinding of the beam, including groove processing, you will need:

Prepare or purchased in advance:

• construction forests, goats or ladder;
• extension cord;
• a set of grinding paper for rough, medium and finish processing;
• construction vacuum cleaner for dust removal if the work is carried out inside the house;
• wooden bar, stapler or slyphbuma holding;
• Protection tools. glasses, respirator, headphones;
• cleaning tools.

To work, you may additionally need a chisel and a hammer to align large defects.

The main work is performed with a grinding machine. flat surfaces are aligned. The tool is reliable, characterized by high performance. Work will not require large costs of physical strength. However, a profiled beam with round edges is inconvenient to process in this way, it is better to take planetary grind.

Using a corner grinder or drill to work to align large surfaces is inappropriate:

• The corner grinder will not withstand prolonged continuous work, frequent breaks for cooling the tool will be required, otherwise the gearbox bearings are quickly out of order.
• The drill is inconvenient in the work due to the need to make great efforts to retain.

Corner grinder and drill are in demand when processing grooves and small areas, removing traces of rotting. For the same purpose, a renovator with suitable nozzles can be used, it can also replace the chisel.

Preparatory stage

Consumptions are harvested in advance, including impregnations, varnishes, paints, mastic.

Leaving a treated tree without protection for a long time is undesirable, this can lead to rapid darkening of the surface, loss of attractiveness.

When you need to grind

Opinion on whether to grind the walls of the log house at once or wait for its complete shrinkage and drying out, were divided. Some believe that the log house will wait until the log cabin will occur and the logs of wood will occur, it is too long, because the process is quite long, depending on many external factors such as:

• Frower cutting season;
• Log manufacturing technologies;
• Wood of wood, its density and humidity;
• Type of insulation used between crowns;
• Climatic data of the region.

In addition, during this period, wood can become infected with a fungus and change its shade.

Others believe that it is impossible to rush with this matter. The darkened color of wood will disappear after grinding, and the fungus is easy to remove using biological impregnation. It is necessary to fully comply with all the necessary conditions for an effective and high.quality result.

For this, the roof must be covered, the structure should completely give a shrinkage, but most importantly. the moisture content of wood should not exceed 20%.

Despite the divergence of opinions, experts still recommend making their choice in favor of the second option. Premature processing and painting of raw walls can turn into great troubles for the owner.

In addition, to turn the construction work, to wait for the readiness of the log house for grinding, it is not necessary. During this period, you can engage in wiring plumbing and electricians, put the floor, ceiling, insert windows and doors.

The necessary tool for work

A working tool must be selected based on what material a log house is built (a chopped log, a looped log or a beam).

Only tools, or rather not even tools, but accessories for work, will be needed in all three cases. these are protective glasses and respirator.

The chopped log

For grinding walls of a log house erected from a conventional log, you need a regular corner grinder with special nozzles. Buying a corner grinder, it is better to make your choice in favor of a professional, or at least a semi.professional tool.

Since the walls will have to be grinded outside and inside, and these are very large areas for work, a cheap and low-quality tool will fail after the first or second walls. over, the grinding of walls very strongly loads the tool, in view of the long.term work process for a long time.

The power of the corner grinder will be sufficient 800-1100 W. You can certainly take more powerful, so to speak with a margin, but for grinding this more than enough. corner grinding with high power, it will be much harder to work. This is due to the fact that it has considerable weight and quite large rotation turns. One wrong movement and a hole appears on a log, which is then not so just smooth. You should also pay attention to:

• The length of the electric cable. too short is not entirely convenient to use;
• Power adjustment. in places uncomfortable for work, for safety should be slightly reduced;
• The place of air fence into the engine. the air fence is desirable that the corner grinder is located from the back, and not from its side walls, so it will be less clogged with dust, which will increase the life of the tool.
• A special winding nozzle for a corner grinder, on which a grinding disk is attached to any construction supermarket. For grinding, circles with different grainness from 40 to 60 are used. for initial processing and from 80 to 100. for finish.

Escalled log

Since the galinded log has a semicircular, perfectly flat surface, the use of corner grinder will not be appropriate. With careless movement, you can make a recess or groove on a log, greatly spoiling the appearance. An ideal way to grind a log house of logs is the use of eccentric grinding machine.

Despite the fact that its performance is much lower, the principle of operation of this tool will make the surface of the log perfectly smooth. The typewriter uses a specially blocking element that turns it off with a strong press, which allows a person who does not have experience in this matter.

Using eccentric grinding machine

The power of the eccentric grinding machine is only 300-400 watts., The number of revolutions is from 8,000 to 12,000 rpm. expensive models are equipped with a special vacuumed bag. This is very convenient for internal work.

On a note! The tool is selected on the principle of “comfortable lies in the hand” so we take. For primary processing, circles with granularity of 40-60 are used, for finish 80-100.

Glued or profiled timber

Grinding the log house of which is made of a beam. performed in two ways.

• The first way is using a well.known angular grinder and grinding circles to us. All work on giving the beam is perfectly even and smooth, in comparison with a round log, you can produce in a much longer time.

This is due to the fact that the beam has a flat surface, to work with which is much easier. However, not everyone can cope with this task. This requires practice and a good ability to deal with the tool, since any error on the wall will be well noticeable. If there is no such practice, then it is better to resort to the second option.

There are two standard types of wooden beams:

• Profiled timber. is a whole log passed through special equipment that betrays a certain form (profile);
• Glued beam-a pre-prepared log, saw it on boards, which are then dried in special chambers up to 10-14% of the humidity. Ready.made boards tightly glue among themselves in a pressing machine in a whole workpiece, from which then the profile of the beam itself is made.

On a note! Due to the fact that glued beams. dried, practically no shrinkage building material, you can proceed to its grinding immediately after the construction of the walls.

Everything is different with a profiled timber, most often it is made from a freshly cut forest, so you need to give a log house to shrink and shrinkage, only after that proceed to work.

• The second method is the use of a vibration grinding machine. This method is not so fast, but better. In addition, the grinding of wooden walls of the house can be done with your own hands, without resorting to the help of an expensive team of specialists.

The machine should be purchased with a rectangular, not a round area. It’s easier to work with such a machine, at a rectangular site a large area of ​​the coating, which will certainly affect the speed of work.

When to grind

The first work, which is carried out at the construction stage or immediately after the construction of a log or a timber house is the primary hemp of intervention joints. Grinding can only be started after a wooden house has passed shrinkage and wood has completely dried up. This condition is especially important to observe if a house or bath is built from a log of natural humidity.

Unlucky wood does not allow high.quality grinding, it must be given to stand and dry out. This may move from six months to two years, depending on the time of installation and moisture of wood. During the academic, villi rises in the wood and all its defects appear, which are easily removed during grinding.

You can grind a profiled beam no earlier than 10-12 months after construction. If the house is made of glued or dried allocated timber, you can proceed to grinding immediately after it is put under the roof and pronounced. A house made of glued beam gives a small shrinkage, which cannot lead to significant wall deformation.

The polished surface cannot remain unprocessed for a long time. Within a week after grinding logs, the log house must be treated with an antiseptic composition. If you miss the time, wood will begin to darken and acquire a blue shade.

The grinding of logs must be carried out not only after the construction of a new house, but also after 5-7 years of operation of the building, when the deadline comes to change the old wall coating. Grinding allows you to remove an outdated paintwork, lighten the color of the tree and prepare it for coloring.

Basic rules and methods of grinding logging

The grinding of the log house includes three stages:

• Black ripening, primary rough surface processing is performed.
• The main processing is to smooth out irregularities and leveling the base.
• Finish processing and preparation of the surface for the application of an antiseptic and coloring agents.

Many people ask: whether the finish grinding of the log house is required, because after the average processing the wood is already even even. To get a beautiful and high.quality coating, the surface should be perfectly smooth. It is impossible to achieve if the finish is not carried out.

Several factors affect the grinding speed:

• type of processed wood;
• surface area and relief;
• type and power of the tool;
• grinding skills and tools;
• the presence in the wood of the resin.

A grinding tool is selected depending on the type of lumber used for construction.

• For grinding a log house and a bath of a ruble, a corner grinding machine is suitable, and a regular angular grinder with special abrasive nozzles is suitable in a different way.For each type of work, circles of different numbers are designed, which differ in grain size. Strict coarse part of the bark, remove knots and other large defects of the material can be abrasive with large grain 0-60. The surface will skin the same abrasive when the old paint coating is removed. Average grinding is performed with a tool with a small abrasive discs. Finishing grinding is carried out in circles 00-120 or by hand with sandpaper with the smallest grain size.
• The log of the log has a perfectly smooth surface, which can be easily damaged with any careless movement of the corner grinder. In this regard, it is better to grind OTCB with an eccentric grinding machine. This tool is able to perform the thinnest processing, as a rule, it is an eccentric machine that a log house is polished.
• The grinding of an unstable, profiled and glued beam is performed using the same angular grinder. Corner grinder provides high grinding performance. However, if there are no skills for using this power tool, it is better to use flat.grinding and ribbon grinding machines, which are perfectly coping with the processing of a flat surface. To polish hard.to.reach places in the corners of the log house is best not by a power tool, but by bar with grinding paper.

Errors when grinding corner grinders

Grinding the walls of the log house is performed in stages and includes three types of processing: rough, thin and finish.

• At the first stage, gross processing of the beam is performed, the task of which is to remove all significant irregularities from the surface and prepare it for a thinner grinding. For this work, an abrasive with the largest grain size is selected. During primary processing, the nozzles are very quickly clogged with dust, and they often have to be changed.
• For the main grinding, sandpaper with a fine grain fraction is used. After processing, a smooth and smooth surface should be made, ready for subsequent painting.
• The finish grinding is not always performed, but in cases where it is required to bring the surface to an ideal state for the subsequent application of a transparent varnish coating. The walls are polished using the smallest abrasive, which allows to make the surface as smooth as possible.

To polish the grooves, an angular grinder is used with a nozzle of a few sizes less than the diameter of the circle. The angles are handwritten by a chisel with a width of the working part 20 mm.

After each stage of grinding, it is necessary to clean the surface of dust using a vacuum cleaner. After all grinding work is completed, the surface is necessarily treated with antiseptics that protect wood from rot and mold. This must be done no later than seven days after grinding.

Grinding a profiled timber or logs with your own hands is carried out in several stages:

• Black grinding (rude).
• Grooves and angles processing.
• Crouping processing.
• Finish grinding (thin).
• Decorative processing of log house with protective compounds and impregnations.

The process of external and internal grinding of a log house requires a frequent change in working nozzles due to the formation of a large amount of wood dust. To clean the nozzles from pollution, you can use a steel brush treated with an antiseptic.

When working with wood, do not forget about the elementary safety rules using personal protective equipment. glasses, gloves, mask and overalls.

Grinding walls from the beam inside the house and outside is performed in the following order:

• Personal means of protection against negative exposure to wood dust are used.
• Grinding is carried out from top to bottom.
• The area of ​​the walls is divided into equal areas, which will make it possible to carry out better grinding.
• The material is checked for the presence of problem areas. the old exfolved pieces are removed, and the affected areas are cleaned of mold and fungus.
• The quality of the hemp is performed, and the resulting defects in the form of cracks and gaps are eliminated by sealant for wood.
• Gross surface grinding with large nozzles is carried out. This will help get rid of existing irregularities and roughnesses. When using corner grinders, discs are recommended to grind in remote areas of the log house. above the window and door openings, near the corners. In this way, you can prevent the possible sparkling of the nozzle and damage to wood. In addition, when processing surfaces, it is better to move the tool with the shoulder joint, and not with the hands, to get the maximum smooth surface.
• Next, nozzles with small grain are used to remove wood pile. The processing of the material with the tool is carried out carefully at medium speeds, which will help to avoid damage to wood and the formation of grooves on the walls.
• The ends and grooves of the log house are subject to thoroughly grinding, since they are more susceptible to the negative impact of external factors. For processing the ends, you can use nozzles with grain size from 40 to 120.
• Hard.to.reach places, as well as internal and external corners, are polished by a chisel with a width of a 25 mm blade width.
• The surface is cleaned of dust with a vacuum cleaner and a brush with a nylon bristle.
• The polished walls of a timber or log house are treated with antiseptic compounds to protect against fungus and mold, with core tools. to ennoble wood, antipypens. to increase burning resistance, acrylates. to protect against the negative effects of atmospheric precipitation. To prevent darkening of wood, polished surfaces are treated with protective compounds no later than 2 days after grinding.
• The logging is painted 36-72 hours after the grinding and impregnation is completed with protective compounds.

Grinding logging is a long and rather painstaking process, the organization of which will require high.quality equipment and minimal experience with wood.

Corner grinder is the most convenient and affordable tool for grinding, but in unprofessional hands it turns into a rather dangerous device, which, with inept treatment, can make many problems. Pets who do not have the skills of using an angular grinding machine very often make mistakes, which are the main cause of poor.quality grinding.

We offer to familiarize yourself with a shirt of windows in a house from a bar

A typical error. the work of a corner grinder at high speeds. Inexperienced masters are often difficult to choose the optimal speed of disk rotation. As a result, the tool at high speed literally “burns” the wood, damaging its front layer. In addition, large turns contribute to the rapid clogging of an abrasive with wood dust, which reduces the life of the nozzle.

Another common mistake is a strong press on the device during grinding. This is the most common cause of formation on the body of a log and a beam of dents and grooves that spoil the appearance of wood. It is not so easy to get rid of these traces, you will have to relocate again, which is not always effective.

Brus grinding. modern mechanical and manual wood processing (80 photos)

Grinding the beam is considered a mandatory procedure after the construction and process of shrinkage of a wood structure. Grinding the beam inside the house and on its front side is carried out, since this is a necessary condition before applying various coatings for decorative or protective purposes.

This will help ensure the even surface of the beam and save it from blue, darkening, damaged areas. In addition, with the help of grinding, you can get rid of the old painting if necessary to apply a new color or in order to update the spoiled coating.

Next, you will find out which tools are suitable for such work and how to use them to facilitate the grinding process. This question does not seem important, however, the speed and quality of internal or external grinding depends on the correct choice of the tool.

Previously, this work was carried out using a chisel or sandpaper, which was very long and not quite high quality. Now the situation has changed because electric tools have appeared.

But grinding places that are not available for modern devices are carried out manually. You can see a photo grinding photo and evaluate all the complexity of handmade and the simplicity of its execution based on electrical devices.

Now we will deal with the set of necessary tools and the rules for grinding various surfaces.
