How to sand the inside of a log house. Sanding logs: why is it needed and what are the features?

Wooden buildings have undeniable advantages. Wood absorbs moisture or dries out, regulating the level of humidity in rooms. Wood breathes, due to which natural ventilation occurs. Wood retains heat and is an excellent sound insulator. But if you don’t take care of the log house and don’t help it, it may lose some useful features.

Why is it necessary to sand a log frame?

Experts insist on grinding. But not everyone listens to such recommendations, believing that the procedure is only needed to improve the appearance of the building. But in vain.

Grinding of the log house is carried out after completion of construction, or after the final shrinkage of the house. The procedure is labor-intensive and requires good physical fitness. It is immediately worth emphasizing the need to use protective equipment; dust and wood particles can damage the skin, eyes, and respiratory tract.

Be sure to wear personal protective equipment when sanding. These are wide glasses with tight-fitting sides, a respirator, headphones and gloves.

The purpose of sanding is to remove the top darkened layer of wood, remove irregularities, and smooth out imperfections. The appearance of the structure is noticeably improved, the natural golden color with a natural pattern is restored, technological traces of processing from crooked cuts and plane marks are removed. The logs or beams are given a beautiful geometric shape, round or otherwise.

The wood gets rid of harmful microflora; the treatment will eliminate mold and fungal formations in the future. The bast layer that has lost its quality is removed by 2-3 cm, the bark is removed, and places where bacteria can multiply and rot can form are cleaned.

Important! The main purpose of sanding is to prepare for applying the finishing protective coating. Leveled walls take less paint and varnish materials, surface adhesion improves, wood absorbs impregnation better.

Treatment with fire retardants and antiseptics protects wood from negative impact environment, improves its properties. Sanded logs with a protective coating are a guarantee of durability, strength, and high performance characteristics of the structure.

A rounded log sometimes has polished areas that appear due to violations of processing technologies; these places repel impregnation and quickly deteriorate, which can lead to contamination of neighboring logs with putrefactive formations. Careful sanding eliminates this problem.

What tools are best to equip yourself for polishing a log house?

Today it is not difficult to acquire the necessary tools for carrying out the procedure. You should arm yourself with:

• grinding machine;
• cutting machine;
• chisel.

Modern technology certainly makes the task easier. You need to learn how to use a grinder by adjusting the pressure. Excessive efforts can lead to defects; you cannot make mistakes so as not to spoil the appearance of the building. The corners and inter-crown depressions are ground with a grinder; the recesses are processed manually with a chisel. It is better to use a chisel 20cm wide.

Important! When choosing tools, you should pay attention to weight, so as not to put too much strain on your hands and power. Tools with low power will heat up, significantly reducing productivity. Quality tool They are produced by Makita, Bosh, DeWalt, and the domestic Interskol is also worthy of attention. The equipment is high quality and durable.

For timber log house You need a belt sander; its use will ensure a smooth surface. Equipped with a special dust collection bag, the machine will make subsequent cleaning of the room easier. I will round the surface of the logs draw machine Grinding is difficult, a grinder and special attachments are useful here. The correct power of the cutting machine is 600-900 W. Nozzles with different degrees of grain. Initially, use a coarse-grained nozzle (40), then take a nozzle 80-100. Disc 125mm, speed 10-12 thousand, preference should be given to a machine with a rear air intake and a long cord that provides freedom of action.

Important! For work, it is more convenient to use two machines, so as not to overheat and not change attachments; first work with the attachment with large grains, then with fine ones. Using plastic attachments; flexible plastic with an abrasive layer is more convenient, leaves no marks and lasts longer.

Grinding process technology

The grinding technological cycle consists of three stages:

1. draft;
2. main;
3. finishing

Rough work is stripping the surface, the main stage is to smooth out irregularities, finishing Treatment with special substances that support the health of wood is mandatory.

The grinding process requires time and skill. In 2-3 minutes you can process 30cm of timber. Forced use greatly slows down the process hand tools in places where the machine cannot reach. The processing speed largely depends on the complexity of the architecture and the resin content of the tree. Frequent replacement of nozzles is required; they become clogged; they should be cleaned with white spirit and a wire brush.

Larger surfaces are best divided into sections; each section should be sanded in three stages with final treatment with impregnating compounds. If you do not saturate the area immediately, it will quickly darken and the work will have to be done again.

Sanding rounded logs

An eccentric grinder will help make the surface smooth and even; working with an angle grinder requires certain skills, without which you can make grooves and depressions. Disk lock option eccentric machine will help get rid of such misunderstandings. It is necessary to use discs with abrasive 30-60 for primary processing and 100-120 for finishing. The required power of the machine is 200-300 W.

Grinding of corners and inter-crown joints

The grooves and corners are polished with a cutting machine. You need to take a nozzle smaller than the disk size. The grooves are ground with a chisel. Some people advise starting with the corners, others think that they should end with them. There is no fundamental difference. It is important to treat the surface immediately after finishing sanding. protective compounds.

End grinding

To process the end of a log, you will need a grinder with 40 abrasive. There is no need for finishing sanding; it is impossible to achieve perfect smoothness. But enhanced treatment with primers and other compounds is required. The ends of logs are especially susceptible to getting wet.

Sanding inside the house is no different. If additional wall finishing is not planned, processing should be carried out with the greatest care.

Processing glued or profiled timber is easier, the surface is smooth, it is enough to remove the top layer that has changed color. Factory-made timber is usually treated with fire retardants and antiseptics. This treatment will last for a year or two. However, then you will have to work hard to return the timber to its original qualities.

Proper processing of timber after grinding

Proper wood processing increases the durability of the structure, eliminates wood damage, and reduces the costs of subsequent maintenance and repairs. It is better not to save on purchasing funds. High-quality compositions purchased in reputable stores guarantee reliable protection wood from natural aggressions, rotting, fungus and mold. When purchasing protective mixtures, you should pay attention to the warranty period.

Impregnation is applied manually, with a brush or spray. To improve aesthetic qualities, many use impregnations with coloring pigments. For correct processing required:

• antiseptics;
• flame retardants;
• glazing compounds.

Antiseptics block mold and rot, fire retardants increase resistance to fire, glazing compounds make the surface more beautiful.

Important! It is preferable to purchase Valtti Pohjuste antiseptic from Tikkurila, Neomid 440, Neomid Bio Color. Antiseptic Valtti Color favorably emphasizes the wood texture. The products are not cheap, but worth the money spent.

Consumption of the composition is approximately 1 liter per 1 m² of sanded surface. White spirit is used to wash hands and arms.

Grinding important stage in the construction of a log house. You can do it yourself, or you can invite specialists. The cost of work is 300-400 rubles per 1 m². Grinding big house– the event is expensive, there are no big difficulties in the work, the choice is yours.

And again we are glad to welcome you, developers and customers construction company SEC "Russian Izba" This time we will talk about such a necessary operation as polishing a log house. Why do you need to sand logs, if the wood is very durable and is aesthetically attractive in itself, how difficult is this work, is it possible to do it yourself, and how much does it cost if you contact an organization for sanding - we hope you will be given detailed answers to all of the above questions and clear answers this article.

So, the first question that certainly interests you is:

What is the price per square meter for sanding a log frame?

The total cost of work is determined taking into account the following factors:

• quantity of consumables per square meter or one pass of the tool;
• prices for specialist services, which are determined depending on the area of ​​the walls;
• quantity of antiseptics, work on their application.

I’ll say right away: different construction companies and teams set their own prices. They are guided by their own experience, the availability of professional tools, ambitions, and so on. Therefore, of course, I cannot say exactly how much the builders will ask from you. But I can announce the prices for polishing at the Russaya Izba SEC.

On average, grinding in one pass costs customers construction company SPK "Russkaya Izba" V 300-400 rubles per square meter, but prices vary in each specific case - depending on the total surface area, whether grinding is needed inside or outside, and on whether the customer is applying for the first time or is a regular customer of ours. In a word, everything needs to be clarified, as they say, on the spot. Therefore, leave a request, call – we’ll discuss everything!

If you think that the prices are too high, we would like to clarify that sanding is enough complex look works It requires not only a professional tool, but also a lot of experience! Generally for long years From our work, we have learned that at the stage of designing a future home, the customer does not even realize what a burden of problems he is shouldering. And when all the problems appear clearly, it is important that the contractor he chooses is reliable. After all, some may even turn their backs! And reliable - and will do everything conscientiously, and will answer any question, even years after construction log house, and will name the real price. So, without proper experience, a log house can be seriously damaged.

What does it mean? To process wood, an angle grinder (or grinder) is used – we’ll tell you in more detail below – and you need to know how to use it! Yes, not just know the principle, but be able to smoothly move along the surface, so that the angle grinder does not jump around under your hand, crashing into a tree, making ripples and waves. This is most often the case with inexperienced craftsmen. Here, firstly, the usual technique of working is important - not with the hands, but with the shoulders and forearms. And secondly, you need to choose the right attachments with different grains. We'll tell you about this too.

The main thing is for you to understand that if you don’t know how, it’s better not to take it on. You’ll waste a bunch of material – for the same amount that professionals would charge for the work (we’re not exaggerating!), and you’ll already waste your nerves and time...

Now about the process itself.

Sanding and painting after sanding the walls of the log house

If you still don’t understand why it is necessary to sand the log walls of a log house, let us explain. The main purpose of sanding is to give the building an aesthetic appearance. Wood, even the most durable, darkens over time. In order to make the walls light, to see a unique pattern on them natural wood, smell it, and need to polish it. But it is equally important that with the help of this operation the log is cleaned of mold, mildew, bark residues, burrs, cracks, and so on. The logs become smooth without losing their protective resinous layer! And, of course, varnishes and paints adhere better to a sanded surface, and their adhesion to the surface increases. Excellent absorption into smooth walls and antiseptics.

Grinding is carried out after the end of the shrinkage period (at least 6 months after construction) and before the start of all finishing works, installation of windows, floors, ceilings, laying communications. Moreover, keep in mind that errors in finishing the walls of a log house made of planed logs cannot be hidden, as is the case with timber, for example, under the floor, insulation or lining. The sanded surface must be perfectly smooth. One more point - by the time processing of the log house begins, there must be a roof on it - otherwise the work will be useless.

It is important to think through and organize the order of work. If the blue color is already spoiling the appearance of the logs, the wood must first be “whitened”. To do this, use an antiseptic, saturate the walls with it, let it dry thoroughly, and only then start sanding. It is better to carry out the grinding process itself in parts - immediately covering the cleaned surfaces with an antiseptic. By leaving treated logs uncoated for just a few days, you run the risk of starting all over again - the logs will have time to darken again.

Sanding is done in three stages - two passes with a grinder, using sandpaper different factions, and the control pass is done manually. They also do the treatment of all hard-to-reach places by hand. If the log house has two floors, work is carried out starting from the second floor. There will be a lot of dust - you need to prepare to remove it in time with a vacuum cleaner and broom. For the same reason, take care of personal protective equipment in advance - respirator masks (better than paper ones, they generate less moisture when breathing), goggles and gloves. If already installed plastic windows, it is better to protect the mechanisms in them with film (covering the windows with it); you can also line the roof membrane with film. Although I’ll remind you again - it’s best to sand while there are no windows, floors and ceilings yet (these are the most difficult areas). It is also very difficult to work the corners of the cuts - the grinder cannot reach there, and you will have to go through it with a chisel.

After processing the log house, it must be coated with antiseptics and fire retardants. If desired, paint or varnish.

And, of course, a very important question that we must consider is

How to choose a tool for sanding log walls?

We have already said that for round log An angle grinder or grinder is suitable. Whereas for a timber house, belt grinding machines are used. You need to choose a grinder based on power - the ideal option is 850 watts, no more is required. When purchasing, hold the tool in your hand - it should be light, otherwise after several hours of work you will no longer be able to raise your arms. And be sure to pay attention to reliability - a Chinese angle grinder will break down very quickly, and you will only lose the money invested in it.

You will also need attachments - it is very important to understand the process here. Do not buy super sophisticated ones - with Velcro, rubber and others. An attachment is required to which the grinding disc is attached with a bolt. Discs come in different diameters, in our case we need a diameter of 125-150 mm, no more. You will need a lot of them - from 1 to 3 pieces per square meter! By the way, do you know how to correctly calculate the area log walls? We take several control measurements, measure all the bends of the crowns. For example, you have a ceiling two meters high, but the actual height of the wall of the log house turns out to be three and a half meters! So think about it correctly.

For the first pass, you will need sandpaper with a coarse grain - fraction 40 (it will also be suitable for sanding the ends of the frame). The second pass is performed with finer sandpaper - 80 (or 60, as a last resort). For manual operations, stock up on a hammer and chisel.

Please note that the outer layer of a softwood wall, although dry by the time of sanding, still contains resins - so consumables will quickly clog. On average, it will take 2-3 minutes to pass 1 linear meter of logs with a diameter of 30 cm (if a professional works!). The same amount for replacing material.

Professionals sometimes grind grooves with a special flat attachment on an angle grinder, but it is not suitable for an inexperienced beginner. It is better for him to go through the grooves manually. After completing the entire sanding process, be sure to blow off all dust without a trace from the walls, and especially corner connections crowns

Let us separately mention such an important operation as

Grinding the ends of the log house

The fact is that the outer ends are subject to constant exposure natural factors, and suffer the most. Sanding will help clog the natural channels in the wood and reduce its absorption. Ultimately, the log house will last a long time – and that’s exactly what we need!

The ends need to be sanded with coarse sandpaper, and then thoroughly polished! An unpolished end will absorb water like a sponge. And, of course, process it immediately - no later than two days after sanding. The surface will become smooth and hard, without noticeable lint, and any composition will fit perfectly on it - be it a protective one or a paint one.

Well, that's probably all important aspects the process of grinding a log frame, which we wanted to tell you about today. Of course, there are a lot of nuances in this work - however, like in any other, and questions will certainly arise along the way. Especially considering that each log house, like a living creature, is special and unique. But this is exactly why we love Russian log houses so much!

But the result of good, professional work will certainly please you! Look again at
log houses and baths manual cutting from the construction company SEC “Russian Izba” - isn’t such a bright and spacious mansion worth going through the difficult path of construction, with all its problems? And if you get a reliable performer, rest assured, he will take on most of the worries. This is exactly how we work.

Over time, any wood loses its original appearance and darkens. In some cases, the cause of darkening and even blackening is mold bacteria, which multiply very quickly in undried wood. But even completely dry wood becomes dark over time due to exposure to sunlight and moisture. That is why the wood is sanded before applying the coating.

Sanding a log frame allows you to remove the top blackened layers and prepare the wood for further processing.

Purpose of grinding

During construction wooden houses many developers want to emphasize the pristine beauty of wood texture, rejecting this type of finishing such as painting. To do this, the log house is treated with transparent or tinted products, which, along with decorative functions They also protect the wood from rain and snow. Often the substances included in the coating form a kind of ultraviolet barrier that protects the tree from exposure to the sun.

The problem when processing wood is related to the fact that the log house cannot be covered protective equipment straightaway. Any house cut from a log or timber of natural moisture must first shrink. In this case, the wood will dry out and the humidity will be no more than 20%. Only in this case is it possible to apply various protective coatings. However, under natural conditions, wood drying takes months and even years. During this time, the log house will definitely darken and become gray. In this case, grinding will help, which will precede treatment with protective compounds.

Do I need to sand?

There are several types of wooden houses, which are subsequently subject to treatment with protective agents:

• frame houses covered with wood materials;
• log, from natural or rounded logs;
• lumber, from sawn or profiled timber of natural moisture;
• lumber, from laminated profiled timber.

Frame houses are usually sheathed with dry materials that can be processed immediately. It could be sheets moisture resistant plywood or planed profiled boards. Often such materials are treated with protective and decorative agents in advance, before they are mounted on the frame. In this case, grinding is not necessary.

Natural and rounded logs

Houses from natural logs are made using debarked timber of natural moisture. They shrink for a very long time, and drying takes 2-3 years. To reduce drying time, log houses made from such logs are usually installed in winter, when the moisture content of the wood is lowest. But in any case, processing of such a log house will occur only after drying and polishing.

A rounded log is made from a regular log by processing it on special machines. According to the principle of operation, they are similar to lathes. In this case, the top layer of wood is removed, and the log has the same diameter along its entire length. Removing the outer layer removes the strongest fibers. Protecting such a log from external influences required. But since the humidity of the rounded log is high, it also has to be dried naturally, that is, already laid in the log houses. During drying, the surface of the log may take on a uniform brown color, so treatment with protective compounds is possible only after sanding the rounded log.

Natural moisture timber

The timber is obtained by cutting a log at a sawmill. Drying of such logs occurs under natural conditions. In this case, the core is used to make timber, and the layers lying closer to the outer fibers are used to produce boards. Often the timber is then passed through special machines that give it a special profile. Thanks to this, it acquires grooves on the lower surface and tenons on the upper. When assembling a log house, the tenons are tightly inserted into the grooves, thereby ensuring the installation of warm, waterproof and windproof seams.

Since ordinary logs with natural moisture are used to produce timber, a log house made from such material must also be dried. Due to the fact that the density of the timber is usually less than the density of the surface of the log, drying occurs a little faster. However, during drying the timber still manages to darken. And in this case, before treating the log house with protective agents, it must be sanded.

Glued laminated timber

Glued laminated timber is obtained from boards or their scraps. In appearance and structure it resembles layered cake. Such timber is very convenient to use, since the fibers of the boards that make it up are located in different directions. The timber does not warp or behave when exposed to temperature and humidity.

Before gluing, the boards are usually dried and planed, since smooth surfaces stick together better. After gluing, the timber structure is kept for some time in drying chamber, and then undergoes profiling, as a result of which, as in the case described above, the product acquires grooves and tenons.

Note! After several dryings, the wood of laminated veneer lumber already has low moisture content, so a log house made from this material can be treated with protective agents immediately after assembly.

However, even in this case it is not always possible to do without grinding work. The fact is that while the log house, rafters are being installed, the roof, windows, doors are being installed and processing is taking place on the outside, the surface of the timber inside the room can still change its appearance. Therefore, during finishing work inside the house, the walls made of timber are polished. As a result, the surface becomes perfectly flat, smooth and light.

Grinding rules and techniques

The process of polishing a log frame is simple. It can be done with your own hands, and if you have the necessary tools, even a novice carpenter can handle it.

You will definitely need a grinding machine. Depending on what type of log house is to be sanded, you will need to use either an angle grinder (grinder), a belt grinder, or a vibratory grinder. In addition, you will need disks and circles. Again, each type of log house and each type of grinder will require its own consumables.

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

There is also such a relatively new tool for polishing a log house, like a nylon brush. It allows you to better highlight the texture of the wood, leaving more wood without erasing excess. You can use it in the same way as a grinder.

Using an angle grinder

To polish a log frame, especially a natural one, it is better to use a grinder. Discs with wire hairs, similar to a round brush, are used as consumables. Another option - petal circle with segments sanding paper. With such discs and wheels, grinding is done very quickly, but roughly. They are convenient to use when it is necessary to remove old worn-out coating. The disk rotation speed should be chosen low - about 8-10 thousand revolutions per minute. The same tool can be used for primary grinding of timber frames.

For finer grinding, special attachments are used, to which round discs made of sanding paper are attached. back side The paper is covered with lint, and the nozzles have many nylon hooks in their design. The sanding disc is simply applied to the attachment and secured like a Velcro fastener on clothing. Primary grinding can be done with discs with a grit of 40-60, finishing grinding is carried out with discs of 80-100. The number shows how many abrasive grains there are per one square centimeter. Obviously, the higher the number, the finer the grind and the smoother the surface.

Application of an orbital sander

It is unsafe to grind with a grinder near the joints of logs, since a disk caught in the joint may “bite.” Another unfavorable factor is the presence of a jute or moss gasket between the crowns. If the brush disk gets caught on this gasket, the angle grinder can easily be torn out of your hands. In these conditions, it is better to use an orbital sander.

If the log house was cut with a residue, that is, the ends of the logs protrude beyond the outer line of the log house, internal corners are formed, which are very difficult to process. In this case, using an orbital grinder with work surface in the form of an iron. The sharp angle of such a machine can reach even the most inaccessible places. If this does not help, the internal corners at the intersections of the logs can be processed with a chisel.

Very often, when profiling, a chamfer is made at the corners of long edges of timber, that is, the corner is cut off a little. This is done in order to give the timber more interesting view and prevent rainwater pouring down the wall from flowing into the joint between the crowns. To process such a chamfer, it is also best to use an orbital grinder.

Working with a ribbon machine

A log frame can be sanded with a belt sander. In this case, it is necessary to ensure that the direction of movement of the tape coincides with the direction of the wood fibers of the beam. Otherwise, transverse scratches will appear on the surface, which will give the surface a not very attractive appearance.

Whitening

It often happens that log wood becomes infected with mold fungi during drying. After grinding the surface becomes smooth, but separate areas acquire a gray or blue tint. On dry wood it may be barely visible.

If such a surface is wetted, then black and blue spots will appear very clearly, ruining the appearance of the log house. The same will happen during the application of the protective coating. To avoid this, use special means– wood bleaches.

These compositions usually contain chlorine-containing substances. They treat the affected areas of the surface, dry them, and after that the grinding is repeated. Usually one or two applications of bleach are enough to restore the wood to its original appearance.

Safety precautions and remedies

Sanding a log house is accompanied by the release of a large amount of wood dust, which can also be mixed with mold fungi from the affected areas. Inhalation of such dust is very harmful to the human body, so work must be carried out in a respirator. Some models of grinding machines are equipped with special outlets for connecting them to vacuum cleaners. This is very convenient, as it allows you to immediately remove dust from the sanding area. Safety glasses must be used to protect your eyes.

Workers' hands must be protected with thick gloves made of rubber, tarpaulin or split leather. It is not allowed to use knitted or woven gloves, as they may get caught on grinding wheel or sanding machine belt. In this case, injury is inevitable. When working with a vibration grinder, you can use special gloves with a vibration-damping effect.

At correct execution Sanding will help restore the log house to its excellent appearance, and subsequent processing will preserve it for many years.

Sanding a log frame is a process that is more recommended than necessary. However, it is after such treatment that the structure acquires an aesthetic appearance and is considered protected from negative factors. By following the step-by-step instructions, you can polish the frame of the bathhouse yourself.

Selection of tools for polishing baths

To begin with, it is important to choose the right grinding tool. Often, to carry out this procedure, a grinder with a special attachment or a special grinder is used. A lightweight model with a comfortable handle, smooth speed adjustment and rear air intake is ideal. It is more convenient to work with two machines: one with coarse, the second with fine abrasive.

As for abrasive attachments, it is preferable to choose plastic ones. They, unlike rubber ones, do not leave black marks on the wood upon accidental contact. Remember that frequently changing attachments and using the same tool can lead to overheating.

Initial grinding is carried out with discs with a grain size of 40-60. It is enough for about 4 meters of log processing. If the log house is made of coniferous wood, then it will become greasy with resin and dust. This will lead to a decrease in performance characteristics, which means it will reduce the quality of work and increase the load on the tool. Therefore, there is no need to skimp on abrasives. Secondary processing is carried out with a disk with a grain size of 100-120.

Please note that to sand rounded logs you need to use an eccentric sander. The grinder is suitable for processing timber. She's different high power, and therefore can damage the wood with intense pressure. The sander blocks the disc when pressing hard.

Preparing for polishing the bath

It is recommended to grind the frame after its main shrinkage, before caulking. It is worth carrying out the work before the windows are installed, since a large number of dust will settle on the fittings and components of the windows.

Working with raw wood is very difficult. However, if the bathhouse is assembled from dried logs or beams, then the treatment can be carried out immediately after installing the roof. This process is time-consuming and requires serious effort.

Before starting to sand the sauna logs, we inspect the surface for defects. When peeling off some elements (the so-called “petals”), carefully lubricate them with glue and leave for a day until completely dry.

External polishing of the bathhouse frame

When starting work, be sure to protect your eyes and respiratory tract from dust. To do this, you need to stock up on goggles and a respirator. If you have no grinding experience, it is recommended to initially “get your hands on” in inconspicuous areas.

The procedure for polishing a bathhouse outside

It is best to start sanding from the bottom up. We perform the procedure in the following sequence:

• We grind the surface of the log with a grinder with a coarse abrasive (eccentric machine).
• We process the grooves with a grinder with a smaller attachment (the tool is used regardless of the type of beams). In this case, the disk must be 1-1.5 cm larger than the nozzle. Otherwise, the angle grinder will jam in the groove and may break out of your hands, which will cause injury.
• Using a chisel, remove the top layer in the corners. If desired, this procedure can be carried out at the initial stage.
• We grind the ends only with coarse abrasive (30-40). To reduce the lint on the surface, hammer it with a hammer or burn it with a soldering iron.
• We repeat the procedure on each wall.
• Carefully remove dust from the surface before further finishing. You can use a vacuum cleaner and brushes for this.

Please note that it is not advisable to use the tool at too high speeds. Otherwise, deep marks will remain on the wood.

Finishing the outside of the bath

To give an aesthetic appearance and protection from the negative effects of precipitation, fungus needs to be given attention additional processing logs Each wall must be coated with compounds immediately after sanding. Otherwise, it will darken within a day, and all the work will be in vain.

When finishing, follow the following instructions:

1. Apply a layer of primer. The procedure can be carried out using an electric spray gun or brush.
2. If desired, we paint or bleach the surface to highlight the shade of the wood structure.
3. We treat the log house with fire retardants.

It is better to choose paint and varnish for finishing that is based on a chemical solvent. Their water-based counterparts lead to pile rise after the first painting. Special attention It is worth paying attention to the ends of the bath - due to the rough surface, they absorb compounds in large quantities.

Internal sanding of bath walls

If planned interior lining log house, then you can grind the inside of the bathhouse only with a coarse abrasive. If the walls will not be sheathed with anything, then it is necessary to sand them to perfect smoothness.

It is better to carry out the initial sanding of the walls before the “finished floors” are laid and the ceiling is covered. We carry out the work in the following sequence:

• We remove the rough layer of bark with a grinder with a coarse abrasive or a grinder.
• Using a grinder, we process the groove and corner areas.
• We carry out grinding with fine abrasive material (120).
• We sand the joints of logs and the most inaccessible places by hand. To do this, the abrasive material can be wound on a block. This is a rather labor-intensive, but most effective process.

Upon completion of work on one wall, it is necessary to sweep away the dust, thoroughly vacuum the surface and coat it with an antiseptic. The same process must be repeated after complete sanding.

Finishing the bath inside

When starting to apply antiseptics, make sure there are no caulks. Otherwise, they can be sealed with sealants. Finishing we do it in this order:

1. We apply a layer of antiseptic composition to protect against fungus and mold.
2. After complete drying, we treat it with a glazing solution to give the room a more aesthetic appearance.
3. We treat the ends with an acrylic moisture-resistant solution. Let it dry and apply a second coat.
4. We coat the surface with a fire retardant to increase fire-resistant characteristics.

Profiled and laminated timber usually does not require additional leveling. It can be sanded with an eccentric machine if it is necessary to remove the top darkened layer. This process will take longer than processing with a grinder, but the result in this case is high-quality.

Abrasive-jet grinding of a bathhouse frame

IN Lately The abrasive-jet processing method has gained popularity. Its essence lies in the use of a special apparatus from which sand comes out under pressure. This is a non-contact grinding method. Thus, you can clean the surface of the wood from dirt, paint, burning and give it impeccable smoothness.

Sanding with this tool is easy and quick, and the quality is the highest. Due to the created brushing effect on wood, an original pattern is obtained, emphasizing the naturalness and sophistication of the material. This treatment looks exclusive and expensive. Such grinding is usually carried out by specialists with special equipment.

And finally, we present to your attention a video about polishing a bathhouse frame:

Sanding the walls of the bathhouse is carried out not only after the construction of the structure is completed. It is also performed to refresh the appearance of an old log house. This process is labor-intensive and time-consuming. However, if you follow the rules, anyone can polish logs in a steam room with high quality.

After completing the construction of the log house, a grinding process follows, which will help give the wood an aesthetic appearance and make it stronger. We will discuss the technology of sanding a log house with your own hands and what to polish a log house below.

Types of log house

The construction of a log house opens up many advantages for its owner, such as:

1. Eco-friendly home - wood is a clean and harmless material that does not cause allergies and is safe for both adults and children.

2. Wood regulates indoor humidity - thanks to natural properties moisture absorption, wooden frame is able to absorb moisture when there is an excessive amount of it, and release it if necessary.

3. The ability of the log house to breathe provides the room with constant natural ventilation, and at the same time does not release heat. This has a positive effect on the coziness and comfort of staying in such a room.

4. Wood has low thermal conductivity - so the house heats up very quickly.

5. The log house is resistant to deformation, its walls are light and do not require the construction of an expensive massive foundation.

6. In addition, wood is an excellent sound insulator; it has high frost resistance and, in comparison with the construction of brick or concrete house, is cheaper.

Before you begin to study the technology of grinding logs, you should familiarize yourself with its main varieties. As you know, a log house is called wooden building, made from logs pre-treated special technology. For and production choose coniferous or hardwoods trees. Basic requirements for the material:

• lack of moisture;
• diameter from eighteen to forty centimeters;
• absence of rot, dark spots, bugs, etc.

During the construction of a log house, logs are stacked one on top of the other, one row of logs is called a crown. The first row of logs has the largest diameter, since they are subject to greater load. Down side Each log has grooves, which are:

• semicircular,
• triangular.

To ensure that the walls of the log house are stable, insert tenons are used, which are located alternately on each of the logs. Due to the fact that the wood for the log house is dry and is strongly compacted during the installation process, it settles in the first few years of operation of the log house. This factor must be taken into account when determining the height of the building.

The grinding process depends on the angle of the log house, so we suggest that you familiarize yourself with the main types of log houses in relation to the type of corner of the building.

The angle is the connection of two logs with each other, the strength and integrity of the entire log house depends on it. In addition, the corners significantly affect the thermal insulation of the room, since improperly equipped corners of the log house will make the room cold and reduce the duration of its operation.

Among the varieties of log corners, there are two main types:

• with the presence of a remainder,
• with no remainder.

The first option involves the protrusion of the logs by twenty to thirty centimeters, beyond the building. These corners are distinguished by their practicality, ease of manufacture, low thermal conductivity and lack of wind. One of the significant disadvantages of this type of corner is the increase in the amount of wood required for the construction of a log house. Although, if you compare these costs with the costs of insulating corners without any remainder, they will be almost the same.

Corners without residues involve securing the frame using wooden locks cut at the end sections of the logs. In such a log house, the ends do not protrude beyond the building. The only advantage of this type of corners is their more attractive appearance. But the disadvantages are that the corners have more, since a small space is formed in the connecting parts, through which the wind enters the room, so they require insulation. In addition, the work of constructing such a log house takes longer and requires large investments, since in order to build locks at the end of the logs, you need to attract specialists and pay for their work.

General concept and reasons for grinding a log frame

A log house consists of logs, but during use, due to the presence of bark, they begin to darken and lose their appearance. This happens because moisture is absorbed into the unsanded areas and rotting occurs in them.

To increase the service life of the log house, its external treatment is carried out, which includes the process of sanding and coating the wood with special compounds that make it waterproof, fireproof and antiseptic.

The process of polishing a log frame is quite labor-intensive and requires from its performer not only special skills, but also certain tools and a lot of time. If you don’t have time, then it’s better to entrust this issue to professionals who will carry out the polishing quickly and efficiently, while the log house will serve its owner for many decades.

Consequences of grinding:

• protection of wood from the formation of fungus and mold;
• attractive appearance;
• After sanding, a clear wood texture can be seen.

In addition, we suggest considering the advantages of polishing a log house:

1. Mechanical restoration wood allows you to get rid of roughness and cracks, and also helps to improve the aesthetic properties of wood.

2. Wood that has been sanded has high adhesion to paints and varnishes.

3. Sanding the frame - preparatory stage, which allows for further finishing of the entire building.

4. After sanding, the wood has a beautiful texture, which is the main decoration of log houses.

5. Sanding prevents premature aging wood

If you have free time and want to do the grinding yourself, you first need to decide on a tool that will be useful in your work. To make work easy and convenient, choose a tool that is not too heavy, but still has good power.

An excellent solution would be a belt sander, which will help you do this job efficiently. To facilitate the grinding process, such tools have built-in bags that collect dust and sawdust during grinding, so additional cleaning after completing the work is not required.

If the log house is made of logs having a semicircular shape, then draw machine can't handle this kind of work. Then a grinder comes to the rescue, which has special grinding attachments. Use special disk, covered with sandpaper. For hard to reach places great solution will use a chisel.

Pay attention to the weight of the grinder; if it is too heavy, it will be inconvenient and difficult to work with. Recommended power from 600 to 900 W. Choose tools from trusted manufacturers and ask for a warranty on the product.

Please note that sanding work on the log house begins after the wood is completely dry. If you start work immediately after constructing the log house, then wet wood will not make the surface even and smooth.

Stock up on a certain number of attachments that have different grain sizes, since certain areas of the log house require individual grinding. In addition, when carrying out primary grinding, it is better to use a nozzle with large grains (forty), and when finishing grinding, an nozzle with a grain size of eighty or one hundred is quite sufficient.

The grinding process consists of the following stages:

• rough peeling;
• medium processing: smoothing the surface and removing irregularities;
• fine processing;
• sanding before applying varnish or paint.

During the process of sanding a log house, you will need to change attachments very often, because resin and wood dust wears them out. To clean the nozzle from any accumulated wood parts, use a steel brush, but first treat it with white alcohol. Please note that such an attachment will work worse and will wear out faster.

The speed of the grinding process is affected by:

• tool skills;
• type of tree;
• log area;
• presence of complex elements;
• tool power;
• the amount of resin in the tree.

The average speed of grinding work per linear meter is thirty centimeter timber is two minutes.

Do not forget about safety precautions; during the work process, there is dust, resin and sawdust in the air, which gets on the mucous membranes of the mouth, nose and eyes, so when grinding timber, it is recommended to wear a mask and protective clothing.

To work you will need:

• angle grinder or grinder;
• parquet- grinder disk or tape type;
• grinding attachments;
• vacuum cleaner;
• respirator;
• points.

Start the grinding process after a certain time has passed, after the construction of the log house. The building should exhibit minimal shrinkage. An angle grinder will help to process large surfaces, and hand grinding will cope with hard-to-reach ones.

To complete the complete grinding of the log house, it interior walls and facade areas, you will need an eccentric sander, a small grinder and a 2 cm chisel.

1. If the walls are too large, it is necessary to divide them into certain zones and sand them in parts. After completing the work, you should immediately cover the surface with special solutions. If one area is sanded in one day and not covered with paint, and the second after a few days, then the work will be done in vain. After sanding, after 24 hours, the log house begins to darken and requires further sanding. According to the recommendations of experts, painting of a log house should be carried out a maximum of 36-48 hours after sanding.

2. The sanding process involves several steps, the first of which is to use a coarse type of abrasive paper. With its help, the rough part of the bark is removed, while the pile of the tree remains unharmed. To get rid of lint areas, it is necessary to carry out a second sanding process, which involves working with fine abrasive paper.

3. If you have no experience in grinding, it is not recommended to use a grinder. This tool has a high rotation speed, and it is difficult for a beginner to carry out uniform grinding with its help. If you apply a little force and press the grinder on the beam, grooves will appear on it, which will spoil the appearance of the log house. Therefore, in this case, the grinder is used only when processing groove and end sections.

4. Before grinding the grooves of the log house, it is necessary to equip the angle grinder with a special attachment flat type. There are two options for such attachments:

• plastic,
• rubber.

It is preferable to choose the first option, since rubber nozzles are not practical, quickly deteriorate and require constant replacement. The diameter of the nozzle should be slightly smaller than the diameter of the replaceable sanding sheets. If the nozzle gets into the groove, the tool will jam and may accidentally be pulled out of your hands; if the nozzle is smaller, then it will not hit the person doing the grinding, otherwise the consequences will be dire.

In order to sand logs, you will need a grinding machine with a grinding wheel, fine sandpaper, a grinder with a wheel and grout. This process is longer and requires great experience working with grinding tools.

Before you start sanding logs, you must wait at least 8-9 days after the construction of the log house, if the weather is dry and warm. In humid weather, the waiting time increases.

The sanding process involves sanding rough areas using a sander or grinder. Then, all areas are processed using grout and sandpaper. This process continues until the timber becomes perfectly even and smooth. The final stage of sanding is recommended to be done manually, especially at log joints and hard-to-reach areas. The most important condition for proper sanding is quickly covering the log house with finishing materials that will reduce the risk of mold and mildew on the wood.

Processing of the log house after grinding

The process of external processing of a log house can extend its service life several times. This procedure consists of sanding and painting using various compounds.

There are a large number of products that are used to process a log house after grinding. There are both domestic and foreign manufacturers. But not all of these products are suitable for treating residential premises, so before purchasing, carefully read the instructions and technical features solution.

Among the mandatory means for covering a log house after sanding are:

• antiseptics that prevent the development of mold and mildew;
• glazing compositions that make the appearance of the walls more attractive;
• flame retardants - solutions that increase resistance to fire.

The main function of log processing is protective. In addition, with the help of modern developments, the natural texture of the wood is emphasized and it is tinted. It is possible to use ordinary wood paint, but in this case, the wood texture will not be visible.

The first layer that is applied during the processing of a log house is antiseptic, then bleaching is carried out, and after that the application of fireproof impregnations.

It is better to paint a log house with a brush or spray. If the house consists of logs, then it is preferable to choose the second option.

Before applying the main layers, pay attention to the evenness and smoothness of the sanding and the absence of caulking. If available, use special sealants that cover the caulks and prevent their interaction with the environment.

Pay attention to the end areas; use acrylic moisture-resistant solutions or liquid glass to process them. But keep in mind that the second option is less safe for residential premises. Apply any of the solutions in two layers, and the first must be completely dry before applying the second.

The walls are treated immediately after grinding, and at above-zero air temperatures. The first layer is glaze. The composition is applied using a brush or spray gun.

The main rule is the use of high-quality products from leading manufacturers for durable wall treatment. If you save on materials, the first thing that will suffer is the log house, since wood is a rather vulnerable material that requires careful care.
