Log cabin caulking: methods - traditional and modern, technology of work, subtleties. Caulking and log house insulation

Usually the construction of a building is not the end point of the entire project. In order for the house to last a good time, it is important to follow the rules of care and preventive maintenance. This is especially true for log buildings. One of the key points you need to know is how to caulk a log house.

What, why, when

A bathhouse or a house that was built from rounded logs or log cabins usually shrinks. In some cases, this value can reach 15–20 cm in the first year. This factor must be taken into account when designing. Such a phenomenon with the fact that part of the moisture is lost and drying occurs. During the course of this process, loose abutments of the material may appear where everything previously seemed to be quite tight. To compensate for this unpleasant fact, it will be necessary to seal the seams. Simply put, this is an event that is aimed at sealing gaps to prevent drafts, as well as reduce heat loss. Caulking should be carried out after complete shrinkage, which occurs within 6-7 months.

The better

In order to carry out the process of compacting the log house as efficiently as possible, it is necessary to acquire not only a good tool, but also suitable material, and also have an idea of ​​​​how to use them correctly. From the devices we need:

• Caulker. This is a small device that in appearance resembles a chisel or chisel. Usually, at least two types are required for high-quality tasks. One of them is called a set. The width of its blade can reach 10 cm. Thanks to it, you can quickly go through large areas. The second will be smaller, about 2-3 cm. It will be needed during the sealing of the corner joints. Skillful craftsmen use a crooked tool that allows you to do the job much better, but requires special skill.
• material to fill gaps. Previously, only natural fibers were used for these purposes. Today, synthetic materials have already been invented, as well as various sealants.
• A hammer. In this case, you can use any that is on the farm, but it is better if it is a small sledgehammer.

Some masters believe that it will be more convenient to work with a wooden or rubber mallet, since the blow is soft, as a result, the logs are not damaged. Opinions may differ, so everyone chooses the most suitable tool for himself.

moss

For these purposes, swamp red moss is used. This is one of the most environmentally friendly methods. It serves as a kind of antiseptic that prevents rotting. It has been used for centuries. This material allows the wood to breathe in the best possible way. You can not lay it too wet, you need to let it dry a little.

If this is not done, then this can lead to the fact that the joints will begin to rot and the structure will become unusable. But laying it dry is also not recommended. In this state, it will crumble easily, and subsequently will not be able to seal the seams hermetically. Before it is hammered, it is necessary to carry out certain processing. A water-based solution (10 l) is being prepared, to which 500 ml of oil and 250 g of laundry soap are added. Everything is mixed until the soap is completely dissolved. After that, the moss is soaked and laid down to drain a little. To ease the formation of the roller, some craftsmen add tow fibers.

tow

It is also a natural material that is very familiar to plumbers. Due to its fibrous structure, it serves as a good sealant. Some masters are not very fond of this fiber. The thing is, it's hard to work with. Also, over time, the tow becomes unusable, which will force you to take out its remnants and do everything again. Before laying, it will need to be treated with a special substance that will serve as an antiseptic, as well as repel insects that can feed on both the fibers themselves and harm the wood.

An excellent material that, like moss, allows the tree to breathe. It is a good odor filter. Additional synthetic inclusions began to be added to modern material, which made it even more durable. The main disadvantage of using this solution is that the moth loves to feast on felt. Before caulking, it is treated with special compounds that repel this insect.

A modern material that is 100% linen and is a waste product. It is a good seal that does not interfere with air circulation. It has some rigidity, which complicates the process of caulking.

One of the best materials. It not only perfectly fills the gaps, but also protects the interventional space from moisture penetration. Birds don't use it to build their nests, so you don't have to worry about pecking at it. It is made from lime wood. Usually it is imported from other countries. The material is soft and flexible.

Jute rope. In addition to its direct purpose, such a caulk acts as a decorative finish.

Sealant

This is the modern method. Many manufacturers have joined this race. The material is supplied in special tubes. It is applied to the joints, after which a beautiful seam is formed.

Which one to choose is the decision of each individual. Everything will depend on the budget, as well as on the availability of a particular material in a particular area. But it is better not to save on the material.

Technology

The process of sealing interventional seams is divided into two types. They are interchangeable and rather complement each other.

• Stretching. This type got its name due to the fact that the material is stretched along the entire seam and the fibers are intertwined. Usually it is used for primary caulking. After the construction of the log house, the cracks are still quite small, so it makes no sense to fill them with a thick layer of insulation and it is useless. The material is arranged in fibers so that they are perpendicular to the logs. With the help of a tool, it is pushed into the cracks. After that, the ends that remain hanging are tucked into a roller and tightly rammed into the seam.
• To the set. This method is used after the log house has shrunk and the cracks have become more visible. To do this, you will need to collect all the fibers in a heap and make ropes out of them, which are then wound into a ball. Moreover, the thickness of such a rope will have to be calculated separately for each seam, because the gaps are not the same everywhere.

After the spread of roll material, the process of sealing seams has been greatly simplified. Primary laying is usually carried out immediately when laying the logs. To do this, roll material is laid on the lunar recess and fixed with a construction stapler. Next, the log is placed in its place. There is no need to carry out additional work after complete assembly.

During primary sealing, it is important not to save material, but also not to lay it in a large layer. One strip will not be enough, so two are stacked. One should go next to the other, and the edges protrude a few centimeters. This is very important to give stability to the log and make it easier for yourself when re-processing is carried out.

Secondary compaction, which is carried out at least six months later, is not the last. Approximately in 4-5 years, when the building sits completely, it will be necessary to process the seams again. You can follow the following sequence:

• We clean the seams of debris and material that has come out or worn out. You can walk around with a vacuum cleaner to make your task easier.
• Caulking should be done side by side, not wall-to-wall. Those. you need to move around the circumference of each row. This is important so that there is no distortion and the building is not damaged.
• You should start from the outside, and then go inside the building.
• You need to unwind the tape. Its length should be 15–20 cm longer than the length of the wall. This is important, because in the process of compaction, folds are formed, for which this reserve will go.
• Now it is important to gently tuck one of the edges of the tape into the slot to fix it.
• Next, using a caulk and a hammer, we make a seal. To do this, raise the hanging end, tuck it in and knock it out. This operation must be completed in several passes. You should not try to score everything at once, as this can cause distortion faster and the sealing itself will be worse. When twisted several times, a seam is formed in the form of a rope, which is dense enough not to let air in from the street.
• We repeat the operation from the inside.
• We move from the lower (collar) crown to the upper one. Perhaps in the upper part it will be enough just to gently tuck the material without much effort so as not to prevent further shrinkage.

You have to be careful not to overdo the layer. During caulking, the log house rises. Making the underlay too thick can cause the rise to exceed the size of a single log. The consequence may be that the dowels will not withstand and the bars will fall out.

Insulation with sealant is much easier. For this, a special lace of a suitable diameter is purchased. It is usually made from synthetic materials. Without effort, he fits into the seam to cover the gap. After that, the mastic is applied. Its layer should be 5 mm wide and 10 mm high. After application, the composition is sprayed with impregnation, after which it is leveled with a small spatula. In the first few days, you will have to curtain the seams from the sunny side, because. usually the manufacturer advises to avoid direct sunlight until completely dry.

The sealant is also used after the application of natural materials. It helps protect the seal from pests and animals. Inside the house, instead of sealant, it will be possible to use twine of sufficient diameter to decorate the caulked joints.

Usually, self-sealing a log house does not cause any particular difficulties and does not require great skills. The only thing you need is patience, because it will take a lot of time.

Video

This video shows the process of caulking with acrylic sealants:

These types of houses are pleasant and comfortable to live in. The smell of wood warms the soul; it awakens in the soul memories of childhood and pleasant memories associated with it.
In order not to waste spiritual warmth even in the winter cold, the construction of a log house must be completed in compliance with all technological subtleties. An important aspect of this issue is the insulation of the walls.

What is the reason for the need to use caulking in the construction of log houses?

The task of caulking a wooden log house is to eliminate the gaps that have appeared between the logs. Caulking makes a wooden house warm, because neither in winter nor in autumn the walls can let the cold into it. It is customary to call caulking and material intended for filling cracks in logs.

In Russia, caulking of wooden log cabins has been used for a long time. Mostly in Russia they built from wood, and professional caulkers were always in price. Such an attitude towards them was determined by the fact that, having professional skills, a real master corrected all the shortcomings associated with the construction, including the warping of the log house. There was a transfer of skills from father to son. Caulkers could form artels, and then, doing the work, they knew in advance that they would do it efficiently. Although it was possible to check in practice the quality of the work of caulkers with the onset of cold weather.

Caulking with your own hands is considered hard physical work. If you decide that you can do this work on your own, choose the right material for the caulking and. The technology of the process must be strictly observed.

Caulk when using a hammer - it weighs 300-400; chisels in 20 mm. You will also need a rubber mallet and a caulk spatula.

It is best to carry out the initial caulking of the log house six months later, after it has been assembled. Secondary caulking is carried out 1.5 years after construction - this time is enough for the house to shrink. If there is a need, the 3rd time caulking is done 5 years later.

In a wooden frame, the walls are compacted. There are 2 types of their compaction. They are called "stretched" and "set". The second method assumes that the fibers of the insulation material will become strands and will be wound into a ball. The gaps will be filled with these strands. With an increase in the width of the slot, the number of strands stuffed into the groove increases. Caulker "stretching" is done in separate strands. After the gap between the logs is filled, a roller is formed from the strands, which is then driven into the groove.

Materials for warming the walls of the log house

In Russia, timber is insulated in the same way as before. Tow, moss, linen ropes, felt, hemp are used for insulation. The advantage of these materials over the rest is that they are environmentally friendly. The disadvantages include a short service life and poor absorption of moisture. Natural materials are a place of accumulation of insects, which is important for both the log house and the insulation.

If we consider modern materials, then jute insulation is considered popular among them, about this material it is written in our article about the insulation of the bath. Delivery of jute fiber comes from India, Kazakhstan, China. Jute has such properties as hygroscopicity and strength, which is noticeably different from others. Even if the air is 80% humid, jute remains dry to the touch, and absorbs only 20% of moisture from the air.

If you are caulking a wooden house, you do not need to use jute felt. Felt consists, in addition to jute, of flax fiber. Jute felt is susceptible to decay processes; he does not have the necessary strength; and even the moth does not favor him too much.

There is another fairly popular material used for caulking, lnovatin. The material is produced from flax waste left after processing the batch. in fact, the material is pressed dust from flax. Its characteristics are rigidity and strength.

Ways

Methods and materials for warming wooden houses, relevant for the Scandinavian countries and North America.

First, it should be noted that in Scandinavia, as well as in North America, it is customary to use polyethylene foam materials for wall insulation, in addition to the already listed heaters. They are made from polyethylene foam and mineral wool.

The construction of log cabins in the Scandinavian countries takes place according to a more advanced technology compared to Russia. The log cabin here is cut with a snug fit of logs to each other, to ensure minimal gaps. Mineral wool is laid between the logs, the edges are processed with a polyethylene foam cord.
In North America, the first settlers, building houses from logs, rubbed interventional seams with adobe and clay. In Russia, by the way, the seams have never been overwritten according to technology.

Grouts for joints

The grouts that exist today are divided into 2 types. In their manufacture, natural material can be used - then it is clay, sand and cement; they are characterized by resistance to moisture and lack of elasticity. Mezhventsovye sealants have greater elasticity - their manufacture is carried out from polymeric materials.

Today, the market is saturated with a large number of different adobe mixtures and sealants, which serve to insulate wooden houses, foreign and domestic manufacturers act as manufacturers.

Now you are already more aware of the process of caulking wooden structures. If you have not left the desire to carry out this process yourself, - know that the successful insulation of the walls of your bath or wooden house will happen if you have patience.

1. When laying insulation between the logs, you need to leave a margin of 4-5 cm. The insulation laid in this way will be easier to caulk, using this method the work will be of better quality. If you do not do this, later the material will need to be placed in the grooves, but this method may affect the thermal insulation in terms of its quality.
2. The house is caulked from the bottom up, in a circle. Alternate wall insulation is prohibited - this can warp the whole house.
3. The work of the first caulk should be carried out six months after the log house was erected. Thus, he will already take his place, sit down, and it will be possible to see the shortcomings of the construction, which the caulk will subsequently eliminate.
4. If the caulking is carried out with high quality, the building can become 15 cm higher - this condition should be taken into account when re-caulking, carried out after 1.5 years, and during the initial construction of the building.

Several factors are involved in the formation of the price of a caulk. They belong to:

1. Building parameters - its height, length and width; in general, these indicators characterize the surface of the log house.
2. The number of log crowns.
3. The material used for the construction of the beam - profiled beam, rough; log chopped or rounded.
4. Type of log joints in the corners.

After 5 years, when the final shrinkage of the building occurs, you will need to inspect the walls and caulk them again if you find new gaps.

Given the complexity of the work - and each seam needs careful and patient processing - it is better to entrust such a procedure to professionals, even if you have a great desire to save on a procedure that requires such a large amount of costs. We wish you successful construction and a warm home under any conditions!

The caulk of a wooden house is an important step in warming the finished building using natural or synthetic heat insulators. Here, every detail matters: the right working tool, high-quality insulation material, work performance technology. Not all homeowners are aware of how to correctly seal interventional gaps and joints in order to reduce possible heat loss, avoid distortion of the house structure, and prevent rotting of wood and heat insulator.

What is the caulking of the log house for?

Thermal insulation of a log house contributes to the preservation of heat in the premises, prevents the deformation of wood and a decrease in its operational parameters. Modern heaters are durable, practical and safe, therefore they provide high-quality caulking of wooden buildings.

Caulker felling solves the following tasks:

• eliminates cold bridges and reduces heat loss at home;
• corrects structural defects in the structure;
• eliminates various flaws in external and internal corners, crowns, door and window openings;
• makes the house more attractive and reliable;
• increases the life of wood.

When is the caulking

The caulking of a wooden house is carried out in several stages, and this is due to the gradual shrinkage of the wood. Maximum shrinkage takes place during the first 18 months after the completion of construction work and stops after 5 years.

1. The first stage of caulking is performed after the assembly of the log structure. In this case, when building a house, thermal insulation material fills the space between the logs so that the edges hang freely on both sides. After installing the roof structure, the insulation is hammered into the connecting seams between the crowns.
2. The second stage of insulation is carried out 1.5 years after the completion of construction work and preliminary shrinkage of the house. The insulating material is laid tightly enough to hide all the gaps and cracks.
3. The third stage of caulking is carried out after 5 years, when the shrinkage process of the log house is considered to be fully completed. All existing defects between the logs are filled with insulation.

Important! For a log house, all three caulking is carried out, and for a house made of timber, which will be lined with siding on the outside, the third stage of caulking is optional.

Materials for caulking

For caulking timber or logs, it is better to use natural heaters with the following characteristics:

• hygroscopicity,
• resistance to temperature changes,
• breathability,
• environmental Safety,
• ease of installation.

These heaters include:

• moss (red and white),
• tow,
• lnovatin,
• jute.

Moss

The safest and most practical material with excellent antiseptic properties. It provides reliable protection of wood from rotting and biological damage.

Moss (sphagnum) is a reliable material for sealing interventional joints: it passes air well and quickly absorbs excess moisture, prevents the development of pathogenic microorganisms and fungi, and as a result increases the service life of wood.

Moss is resistant to fire and decay, therefore it is able to maintain its performance characteristics for a long time. High cost is the only drawback of such material.

Self-procurement of raw materials will significantly reduce the cost of thermal insulation of a house made of logs or timber.

Before caulking the walls, the pre-treated moss must have a suitable moisture level - not excessively dry or wet.

Tow

A practical and safe material that is used for caulking crowns after complete shrinkage of the log house. It is made from hemp, jute and linen fibers.

Sold in pressed bales or rolls. Tow in bales has short and stiff fibers, which complicate the process of driving interventional seams. High quality tape tow has long, elastic and soft fibers.

This material has low antiseptic properties, is susceptible to high moisture, and therefore requires additional treatment with protective impregnations or paints.

The main disadvantages of the insulation include the complexity of laying, the unattractive appearance of the treated seams, and the short service life.

Lnovatin

A natural material for caulking wooden houses, which is produced by pressing short flax fibers into ribbons. Lnovatin has high heat-insulating and moisture resistant characteristics. Such insulation is able to provide reliable protection of wood from rotting and mold damage.

Lnovatin is used for sealing seams between crowns with fixation on metal staples.

Jute

The most high-quality and durable tape insulation for caulking houses made of logs or timber. The material has high heat-saving properties, is not susceptible to rotting and mold damage. Even with prolonged exposure to moisture, jute fiber remains almost dry.

Jute is used for primary and secondary thermal insulation of the house. It has high strength, wear resistance, elasticity and practicality. It fits into interventional seams with fixation on staples.

The only drawback of the material is its high cost.

Caulking tools

If natural materials are used for thermal insulation of a wooden house, then before caulking, prepare:

1. Kiyanku. A small wooden or rubber mallet for laying insulation with wooden caulks.
2. A dial-up caulk. A spatula with a metal or wooden base, blade width 10 cm, thickness 0.5 cm. This is the main tool for caulking log crowns.
3. Crooked caulk. Curved chisel with a flat blade 5 cm wide and 0.5 cm thick. Used to fill fillet joints and gaps in rounded sections of a building with insulation.
4. Road builder. Triangular blade with a special longitudinal groove. Blade width - 17 cm, thickness - from 0.8 to 1.5 cm. The tool is designed to fill gaps of equal width.
5. Breaker caulk. A narrowed wedge-shaped blade up to 3.5 cm wide, which allows you to widen the intervention gaps for the convenience of laying heat-insulating material.

Important! All caulk blades should be slightly dull and smooth to avoid damaging the wood and pulling the insulation out of the seams. Before starting work, the tools are thoroughly cleaned with a clean cloth.

Logging caulking technology

The process of caulking a house from a log house is carried out in stages. There are two caulking methods:

• in stretching
• into a set.

It doesn’t matter what method the caulking is carried out at home, all insulation work begins with the lower crown. Next, we will consider how to competently caulk a wooden structure.

Stretching

Stretched caulk provides for the insulation of the seams between the logs with pre-stretched heaters. For this, fibrous and rolled materials are used.

Fibrous insulation

1. Work is carried out from the ends of the lower crown. A small part of the insulation (for example, tow or moss) is applied with transverse fibers to the seam and clogged inward with a type-setting caulk.
2. At the edges, the insulation is rolled up with a small roller and compacted into an interventional seam.
3. Next, a new portion of insulation is used, which is formed into a roller, and the entire caulking procedure is repeated. This allows you to qualitatively seal the seam along its entire length.

Roll insulation

Dense rollers from roll insulation are much easier to get. For even distribution, the material is gently stretched along the entire length of the seam and applied to it across the fibers.

1. The tape is unwound on a flat surface from one of the corners to the opposite corner.
2. Having picked up the free edge, with the help of a caulk, the insulation is placed in the interventional seam so that the free edges hang down by 5 cm. This fills the entire length of the seam.
3. After the seam is completely filled, the tape is cut off from the roll.
4. The rest of the insulation is driven into large gaps between the logs. The insulated seam must have the same thickness and protrude 3 mm beyond the edges of the grooves.

To the set

Caulking in the set allows you to insulate wide and deep gaps between logs. It uses a larger volume of material, respectively, and the quality of thermal insulation is higher. Tow, hemp rope or jute cord is suitable for this.

1. To caulk a log house with jute (the easiest option for beginners), a small amount of material is unwound and folded into loops. Next, each loop fits into the seam with a caulk.
2. Stitching begins at the top of the seam and then continues at the bottom.
3. On top of the laid insulation, an additional strand is applied for better insulation. The material is leveled along the entire length of the seam with the help of a road builder.

If desired, the insulation of the house in this way can be accelerated. In this case, the driving of the heat-insulating material is carried out using a perforator. The tool is used at low speed to prevent deformation of the seam. Also, a pneumatic hammer with a compressor is suitable for laying insulation.

Caulker corners

The corners in the log house are insulated after the completion of the main work.

To do this, it is better to use a roll insulation and a crooked caulk. The process is carried out as follows:

1. The free edge of the tape insulation is applied to the seam located in the corner and clogged with a crooked caulk.
2. After installing the material, its free edges are rolled up and hammered into the seam.
3. All work on laying insulation is carried out from top to bottom. For uniform driving, the material is gently stretched and straightened.

decorative caulking

If the main task of caulking is the thermal insulation of a wooden structure, then decorative caulking is used to decorate insulated interventional seams.

To give the seams of the log house an attractive and harmonious appearance, experts recommend using a rope and a rope made of jute or flax as a finish.

The rope is carefully fixed to the surface of the seam on galvanized nails without hats, driven into logs at a distance of 18 cm from each other. Decorative caulking is also suitable for hiding unevenly dried joints between the crowns and for additional insulation of the structure.

After the completion of the caulking process, the wooden house should be used as much as possible throughout the year. In winter, a check is made for the formation of new cracks and deformation of the laid insulation.

A year and a half after the first stage of caulking, the second stage is carried out. In this case, a thorough inspection of the structure is carried out, heat-insulating material is added where it has deformed or fallen out, as well as where new gaps or distortions of the log house have appeared.

Caulking a wooden house is an important and responsible event that requires a competent approach and compliance with all stages of the technological process. The quality of the work performed depends on the internal microclimate in the premises and the duration of the operation of the house.

To get rid of the gaps between the crowns and close the cracks formed during the shrinkage of the log house, caulking is carried out: this is the only way heat will be retained inside the log house. For work, you can use various materials, but the technology is the same. How to properly caulk a log house? What is better to use for this?

What is the best way to caulk a log house? The work can be done using both natural and artificial materials. The latter are much more convenient to use, and the process takes very little time, but they have several significant drawbacks.

natural

These include moss, tow, jute, lnovatin, hemp and others.

Moss

Caulking a log house with moss has been performed for a long time, and even with the advent of modern materials, it has not been abandoned. This is due to its unique properties: it not only retains heat well, tolerates sudden temperature changes, removes excess moisture without rotting, but also has antimicrobial and even healing properties.

Tow

Technology using tow is considered one of the most difficult. In the process of drying the log house, the material will become damp, which will begin to rot over time. Therefore, after drying at home or a bath, the old tow is cleaned, and then the caulking of the log house is performed again.

Jute

Moisture-resistant, environmentally friendly and durable material that retains heat well. Due to its ability to absorb moisture, it has a rather short service life (about 3 years). Worn-out jute is not easy to remove from the gaps between the crowns, so it is rarely used.

There are several types of material:

1. Jute tow. In the production of this type of insulation, the fibers are combed to give them the desired direction. The tow obtained in this way retains all the properties of jute, however, the finished material is not very convenient for work: it is rigid, and at the same time not too dense. The process of caulking when using the material becomes more complicated - it is necessary to carry out work in several stages (during the initial laying, the desired degree of density cannot be achieved).
2. Linen jute. Mixed material consisting of an equal amount of linen and jute fibers. It is popular among builders, but needs protection from insects: before use, it is treated with moth and rotting agents.
3. Jute felt. Composed of 90% jute and the remaining 10% flax fiber, the material has the right density for the job, but at the same time retains flexibility. The ease of use of felt makes it an optimal choice. When buying a material, you should choose one whose fibers are longer than 2 cm - it is more elastic and flexible. The only drawback is that moths can damage it, so the felt is treated with a special protective impregnation before laying.

Lnovatin

Material for protection against insects is subjected to chemical treatments, so it cannot be called environmentally friendly. The service life of the insulation is up to 3 years, it is attached to the log house with the help of a construction stapler.

Synthetic

The use of ready-made compounds - sealants - will cost significantly more than if you caulk a log house with tow. However, they are much easier to work with. Usually, in order to reduce the consumption of a synthetic agent, it is used together with a natural one (for example, a cord). First, the cord is closed in the gap, and a sealant is applied on top, leveling the layer with a scalpel blade.

Among the disadvantages of sealants:

1. A number of synthetic products are destroyed by the action of sunlight - over time, it begins to crumble and falls out. To protect the substance from deterioration, strips are installed on the seams that protect the sealant from ultraviolet radiation.
2. After drying, some compounds harden into a dense solid mass, due to which the wood that contracts and expands depending on humidity and air temperature begins to collapse. It is recommended to use only elastic sealants.

Methods for caulking the walls of a house or bath

Caulking and insulation of the log house can be done in two ways:

1. In a set. Suitable for wide gaps. For work, they take jute, tow or hemp. The selected material is divided into strands, wound into a ball.
2. In stretch. In this case, the heat-insulating material is divided into tapes, hammered into the slots.

General rules

Primary caulking of a house from a bar is carried out approximately 6 months after assembly. During this period, most of the moisture contained in the beam will disappear, cracks will appear on the tree, and cracks will appear in the structure itself.

The next time the work will need to be carried out another year later. At this point, the building will finally sit down, and it will be necessary to eliminate the cracks and crevices that have arisen over the past months.

If everything is done correctly, the third time will be needed only after 5 years. However, if the technologies are not followed, the need to eliminate gaps may occur annually. In order for the caulking of a house from a bar to be done correctly, it is worth watching a video with the advice of experienced craftsmen.

1. Work starts from the bottom. The lower crown is sequentially caulked around the entire perimeter from the outside, after that - inside the log house. After that, they move on to the next, acting in the same way.
2. Usually the largest gaps are formed at the corners, so caulking should be especially careful in these places.
3. First, the material is fixed in a slot in a section of about 1 m, then the hanging parts are folded in and tucked in. Using a mallet, the insulation is tightly hammered into the slot until the material begins to spring. When everything is done, move on to the next section.

Caulker with moss

For work you will need:

• pre-dried moss;
• water;
• soap;
• vegetable oil.

Work order:

1. 200 g of soap and 0.5 l of oil are added to a bucket of water. Mix thoroughly.
2. Dry moss is placed in the prepared liquid. Wet fibers will become elastic.
3. They take a strand of material, twist it into a roller, insert it into the slot. Well tamped.
4. Using a spatula and a mallet, the insulation is tightly hammered into the gap.

For the primary caulking of a log house from a bar with the help of moss, it is recommended to use the “stretching” method, all subsequent ones - the “set-up” method.

The use of tow

In the insulation of this type, insects can start over time, and in order to protect it, the tow should be treated with a disinfectant.

Need to prepare:

• tow;
• formalin (it will act as an antiseptic);
• water.

Caulking a house from profiled timber using tow takes place in 4 stages:

1. Formalin is diluted with water to obtain a disinfectant solution.
2. All prepared tow is placed in it and left for half an hour.
3. After removing and squeezing the material, they drive in the tow divided into ribbons using the “stretching” method. The insulation is rammed with a spatula and a mallet to achieve maximum packing density.

Caulking jute

This material is laid using the “set-up” method.

Depending on which type of material is selected, you will need:

• jute itself;
• bitumen or resin (for felt jute);
• formalin (for jute tow).

Work order:

1. Tow is soaked in formalin solution.
2. The material is folded into strands, the slots of the lower crown are filled with it.
3. Using the tool, push the hanging edges.
4. Using a groove, align the position of the insulation layer.

Important! When processing the area around the chimney pipe, about 3 cm of the surface must be left untouched.

Caulking with sealant

Caulking a log house using sealant is the fastest. To work, you will need the synthetic material itself, a cord for filling the gaps, a special spatula for leveling the seams (you can take a narrow spatula), and a mounting gun.

Caulking log cabin provides reliable insulation of the house for the entire period of its operation. This operation is no less responsible than the construction of a log house, if taken formally, you can get a cold, uncomfortable and ventilated house.

Unlike brick and concrete, wood is a special building material, wood is sensitive to the conditions in which it is located. Properly caulking a wooden house means creating normal conditions for building wood, and ensuring durability for the building. In addition to solving the problems of insulation, caulk protects wood from excess moisture and dampness, decay, damage by microorganisms and insects.

Wooden houses are traditionally caulked with a material of natural origin, one of the most popular is insulation made from fibers of a jute plant. In wooden housing construction, insulation from this plant, exotic for Europe and America, surely displaces other materials, jute is widely used by Canadian and Scandinavian builders.

The reason for the popularity of jute fibers was the low price and good performance; on the Russian market, jute competes with traditional Russian flax. If the question arises: how to caulk a house from a bar, preference is increasingly given. With the help of jute, cottages, economy class residential buildings, baths and outbuildings are insulated.

In the countries of South Asia, three "harvests" of jute per year are obtained from one site with a yield of about 2 tons per hectare, Asian producers are able to fully meet the needs of the world market for this product, the advantages of jute material include:

• Environmentally friendly, the fibers do not split and do not form dispersed dust,
• The fibrous mass is homogeneous, does not cake,
• The jute tape is compressed to 1-2 mm without breaking the geometry,
• Jute insulation is hygroscopic, protects the log house from excess moisture,
• Jute can be used to caulk houses from logs, timber carriage, profiled and edged timber.

As a disadvantage, it is noted that the wet jute mass can create a favorable environment for microorganisms and insects. To eliminate this drawback, manufacturers use preservative and antiseptic impregnations, this should be paid attention to when buying material.

Depending on the density, jute insulation is divided into tow tape, batting and felt. The material is rigid and elastic, tends to retain its original shape, which requires attention and certain skills when using it.

How to properly caulk a log house with jute

The house is made of caulk in two stages: during the construction of the log house and after its shrinkage, the first operation is called the primary caulking, the second is the finishing operation. Primary caulking is done in two steps: a jute tape is laid between the crowns during the construction of the log house, after the walls are erected, the seams are processed clean. When laying gaps between logs or timber with jute tape, the following rules must be observed:

• The surfaces of the crown in front of the caulk are cleaned of adhering dirt, chips and sawdust, the jute tape is rolled out on one side of the wall, fixed with a construction stapler every meter. When laying in parts, the edges are joined end-to-end,
• The tape is cut along the side edge of the beam, in a log cabin - along the line of the laying groove,
• The pins are driven through the jute tape through and through, at the puncture site an incision is made crosswise,
• Operations are repeated on the next crown.

The primary finishing caulking is started after laying the walls and mounting the roof, they start caulking from the lower crown. The material is driven into the interventional joints to a state of elasticity using a special tool, after completion of work on the first crown, they move to the second. The operation is time-consuming, requires diligence and considerable effort. According to the prices of builders, the cost of this work is up to 100 rubles per meter.

After completion of work on the outside, the operation is repeated from the inside of the house, the technology for insulating a house from a bar from the outside and from the inside does not differ. The time spent on caulking a one-story 8x8 house can be 5-7 days.

It is important. If you caulk each wall separately, you may encounter the following trouble: each processed seam increases the interventional distance by 3-4 mm; corner connections.

Caulking methods

When caulking cleanly, interventionists drive jute-batting into the slots, the operation is performed in two ways:

• “Into the stretch” - a twist-pigtail of jute-batting with a diameter of 20-25 mm is driven into the gap, in this way seams with large gaps are caulked,
• “In the set” - the slots are caulked with tape insulation 5-7 mm wide, the edges of the tape are alternately hammered into the slot, then the middle part is sunk.

Masters recommend: between the crowns, lay the jute tape with an overlap of up to 60-70 mm, wrap the free edge, knock it into the slot and caulk it “into a set”. In difficult cases, the insulation is clogged with a stretch, the seam is completely processed “in a set”.

After keeping the house under shrinkage, the previously laid layer of insulation is deformed, the interventional cracks open, at this stage of the caulking of the log house, the work must actually be done again. In the process of shrinkage in the body of the timber, deep longitudinal sinus cracks will be delighted, such cracks are caulked with linen tow and sealed with sealant, for individual cracks, thermal insulation with linen material is more effective.

How to caulk the corners of a log house with jute

When caulking a log house, special attention is paid to the corners, it largely depends on whether the house will be warm or not. The easiest way to work with corners,. In this case, the oblo is part of a log or timber, the jute tape is laid on a common surface, as a result, each seam of the corner lock receives its own layer of insulation.

When cutting into a paw, the elements of the castle caulk differently, in the general case, the principle is observed: each joint must be caulked.

Fine caulking is performed in order, simultaneously with crowns.

How to choose jute tape

Jute insulation is selected by density, thickness and width. A high-density jute tape is laid between the crowns, when shrinking, a low-density insulation is more caked, the width is chosen according to the size of the beam, for a rounded log - according to the size of the laying groove. Masters recommend:

• Lay the edged timber with a jute tape 20-25 mm thick, under oppression its thickness will be no more than 4 mm;
• For dry planed timber, use a tape 10-12 mm thick, which compresses to 2 mm.

The interventional seams are caulked with a material of lower density; jute-batting with a density of 500-600 grams per square meter is used to fill the cracks.

Caulking tools

The toolbox includes:

• A type-setting caulk with a blunt blade for working “in a set”, it is better to have a tool of two types: with a 10 cm blade for caulking crowns and a 2 cm blade for slots;
• Roader for laying twists "in stretch", has a wide blade thickened towards the bottom. A semicircular notch is made along the entire length of the blade;
• A caulk with a wedge-shaped blade is hammered into the slots to widen them.

The tool is made of hardwood or soft metal, has a handle that is comfortable to work with. A mallet is used as a percussion instrument - a hammer with a wooden or rubber striker.

Caulker with jute rope

1. The walls of a house made of edged timber do not always have an attractive appearance, it is almost impossible to lay a heater between the crowns without irregularities, so it will not be possible to caulk a log house “by a thread”. You can decorate the facade with the help of a jute rope, which is applied over a layer of interventional insulation, the rope is fixed with clapboard nails.
2. After the finishing caulk, it is advisable to treat the interventional cracks with an antiseptic, the domestic drug "Neomid" is an effective remedy. The tool provides long-term protection of insulation made of natural material from decay, fungus and insects. It has a liquid consistency and is applied with a brush.
3. If the log house is subjected to grinding after shrinkage, the finishing caulk is carried out last - after the completion of the grinding of the walls.

Conclusion

Despite the mass production of synthetic materials, houses continue to be caulked with natural fibers that have excellent thermal insulation properties. Mezhventsovy heaters from flax and jute have specific advantages and disadvantages, all the best qualities are combined in the combined flax-jute material that is gaining popularity.

What material to caulk a country house or a bath, each developer decides independently, depending on the design of the house, the local climate and other conditions.
