How to caulk a log house with your own hands

Caulking of any wooden bathhouse must be done in two stages: after completion of construction and after a year of shrinkage. For the work, the same insulation is used, which is laid between the links during construction. Traditionally, for caulking baths, they use: moss, felt, tow, and hemp. Readers will learn how to properly caulk a bathhouse with their own hands, what tools are needed and the intricacies of the work by studying the article to the end.

The bathhouse will have to be caulked in any case. The main thing is to do the work carefully.

Caulking technology and methods

Two classic ways to fill inter-crown seams – caulk “set” and caulk “stretched”

Wide seams are caulked using the “set” method. The insulation is formed in the form of flat loops and the inter-crown cracks are filled with them tightly, completely, until the insulation enters.

With the “stretch” method, insulating materials are slightly stretched along the fiber in the form of a sheet, and a special tool called a caulk is pushed into the gaps between the crowns. The insulation sheet remaining outside the gap is rolled up with a roller and driven tightly into the gap.

The most difficult thing to caulk is the corners of the house, due to cramped conditions and inconvenience of work. But it is in the corners that you should caulk especially carefully, since the corners are the main cold bridge of a wooden house, and are blown even more than window openings.

The technology is simple, but the work is very long and painstaking. It’s not difficult to master caulking; the point is to fill the seams with insulation as evenly and densely as possible, and the skill, as usual, comes along the way. Caulking is carried out using heat. They start working from the lower crowns, from the very bottom. Fill the seam, passing it around the entire perimeter, first from the inside and then from the outside. After passing the perimeter of one crown twice, you can proceed to the next crown, and so on for the entire frame. Under no circumstances should you caulk walls and corners in sections, or one wall or partition at a time. This can distort the entire frame. The shrinkage of the frame is uniform, but caulking can create uneven rises of the crowns, ultimately leading to a general uneven deformation.

If tape insulation is used, then before caulking, carefully straighten it and lay it out along the entire length of the crown or wall. They start from the corner joint, hammering the end of the tape insulation into it, and then evenly pass along the entire perimeter of the crown, laying and hammering the tape into the gap, and thoroughly compacting it. Caulking requires great care and does not like to be rushed. The insulation strips should not be twisted, but should be wrapped in a tight, tight roller.

It is necessary to caulk a log house regardless of whether it will be finished inside or along the façade. Caulking will not only insulate the log house, but will also not prevent infection and rotting of the logs. It is unacceptable to caulk the log house only from the inside or only from the outside, for the reasons given above - this can cause distortion and deformation of the log house.

Features of jute fiber

For caulking, fibers that have been mechanically carded are used. This makes it possible to obtain a very strong and rigid material. You can purchase fiber in several forms; any of them are suitable for processing seams: coils, tape and ropes. Such a variety of jute forms allows you to caulk seams of almost any size quickly and efficiently.

But experts recommend thinking several times before using jute fibers for caulking. They are afraid of water, which can ultimately lead to rapid rotting. Therefore, the material requires high-quality drying and cannot be exposed to moisture for a long time.

Typically, this material is used to process structures made of chopped logs. Due to the plasticity of jute, during shrinkage it ideally fills the space, adapting to the sagging surface.

At the same time, it is worth understanding that additional cladding of the walls of the bathhouse on top of jute threatens the rapid rotting of the sealant. Moisture will begin to accumulate under it, which will cause damage to the fibers and the possible appearance of fungus, even if the wood is treated with an antiseptic.

Attention! Jute fiber is made from the stems of the jute hemp plant. It is thoroughly dried and then processed using a special method.

How to properly caulk a log house

Cold air will penetrate into small, at first glance, corner joints and cracks, significantly lowering the temperature in the house, and identifying such places is quite difficult. That is why such stringent requirements are imposed on the caulking of a log house made from rounded logs.

Even the smallest cracks and crevices must be filled with insulation as tightly and efficiently as possible, and caulking must be done not only outside, but also inside the log house. Although, in high-quality rounded logs there are almost no gaps left, neither outside nor inside.

Roller caulking is considered to be the most optimal for a log house made of rounded logs, since its quality and efficiency are much higher. To check how well it is carried out, it is enough to determine its rigidity.

It should be hard to the touch and cannot be pulled out with your hands, even if you try very hard. If the caulk passes this test, it means that the work was done with truly high quality, the house will retain heat well, and even with temperature changes, the insulation will not dry out and fall out.

The greatest advantage of rounded log houses is that after professional caulking, the house does not require any additional insulation.

Wood has long been known for its excellent insulating properties, but for the full warmth experience the village has to work hard.

It is necessary to carefully seal the cracks between the logs, thereby insulating the rooms from the freezing ice.

Caulking technology

All! The tool is ready. Next we do the following procedure. We have a bale of tow. We tear out a not very large beard from it and tuck it into a rope. This rope is usually about the thickness of your index finger, but can be thinner or thicker depending on your gaps. After this, we use caulk to drive the resulting rope into the gap between the logs. Here you will definitely notice that your hands are too tender and weak for such work and you will want to take a hammer to caulk more efficiently. Of course, you can do this, just don’t get carried away. You can easily stuff so much tow between the logs that it will tear the log from the log and lift the house. Don't let this happen.

Another subtlety. You can find places where logs, especially for timber, fit together with amazing precision, and you can’t not only insert tow between them, but even drive in our caulk even 5 mm. Do not delude yourself and do not strive to sharpen the tool to the level of a razor! Usually this means that, going around the wall on the other side, we will see between the same logs a gap into which a palm fits! This is a very typical case when the beam is twisted with a screw. Obviously, in this case, you should caulk from the side from which this can be done. And in general, compressing tow beyond any reasonable limits is a mistake for a novice caulker.

And finally, one last piece of advice. When it seems to you that the house is caulked, I advise you to fill the cracks between the logs with narrow slats, or even better, lay an additional strand of tow between the crack and the slats. In section, the wall will look like this:

or, if you have a house made of round logs, then this

Please note that in appearance, a caulked wall made of round timber looks warmer than a wall made of timber. It also seems to me that a log house made of round logs is better

The only advantage of timber is that a house can be built from it without being a specialist, and with only one assistant. I don’t see any other advantages of timber over logs. But this is already lyrics.

Let's talk about personal experience. Remember my neighbor who bought a house that was not only not caulked, but built without any tow at all? So, we tried the described method of caulking with slats on his house, and it worked! Then I did the same to myself and I don’t regret it.

Please note that I wrote all of my advice on the assumption that you are going to decorate your house with some kind of finishing material. If this is not the case, then a worthy completion of the caulking process would be to impregnate the tow, which is visible from the outside of the building, with oil paint. This is usually done in conjunction with painting the entire house. This way, you will protect your caulked house from being caulked by birds.

Finally, I apologize to experts and adherents of the Russian language for being too bold in using the word caulk and its cognates.

Which sealant for cracks is better to choose?

In order for log houses to maintain the internal microclimate, retain heat and keep out moisture and cold, they need to be specially treated - caulked, that is, plugging the cracks between the logs. When building housing, wood is placed on moss for better adhesion, but this is not enough to plug all the holes between the building materials. When drying, additional cracks form in the logs. Therefore, it is necessary to caulk the log house not only immediately during construction, but also a couple of years after construction, when the logs are completely dry and all unnecessary cracks come out.

It is very easy to caulk a log house with your own hands, using natural materials and simple tools. Common materials for log caulking are:

They have their advantages and disadvantages, knowing which you can choose the most suitable material.

Flax wool is a product of crushing and pressing flax. The material prevents the logs from rotting, but is short-lived. Wool felt is warm, but crumbly and loose. Therefore, moisture easily penetrates through the felt, as a result of which the logs are easily covered with rot. Tow can also accumulate excess moisture and cause logs to rot.

Jute is soft wood fibers gathered into a bundle. It is produced from shrubs of the linden family, growing in Asia. The wood product is the most modern and durable material compared to its plant and animal counterparts. Jute fibers are stronger than fishing line and fit together tightly enough to prevent excess moisture from entering the house.

Since this material is completely natural, it is absolutely harmless, does not emit toxic fumes and does not cause allergic reactions in the residents of the house. Unlike linen and felt, jute is resistant to rot and moths, and it protects logs from birds.

The main advantage of the material is its hygroscopicity. The fiber absorbs excess moisture from the logs, so the log house does not rot. In dry weather, jute releases accumulated moisture to the wood, so it does not crack. The disadvantage of jute is that it consists of wood fibers, and therefore reacts to changes in weather conditions in the same way as wood: it shrinks in dry weather and swells in wet weather.

Materials used for caulking a log house

In order to choose the right material for caulking, you need to know the properties that it should have (or at least most of them).

These are properties such as:

high thermal insulation performance;
moisture resistance and resistance to temperature changes (the material works under constant atmospheric influences);
harmless to the human body;
resistance to processes such as rotting and mold formation, as well as “uninteresting” for rodents and parasites;
resistance to mechanical damage;
no pungent odor;
relative durability (at least 20 years) while maintaining performance characteristics.

All materials used to insulate a log house are divided into two groups: natural and synthetic.

Materials for caulking

Historically, the very first material for insulating inter-crown seams was moss. Today it is used extremely rarely for these purposes, replacing it with more advanced tow, hemp, jute and flax.

Tow is a material made from waste from processing plant fibers. It is quite rough and inexpensive, but with fairly high insulating properties. It is absolutely natural and has the qualities of a natural antiseptic.

Hemp is close to tow, but less coarse. It uses exclusively hemp fibers. Hemp can be processed quite well, so it is woven into ropes and cords, and is also used in construction.

Jute (or flax-jute) has a grayish-yellow or golden color. This material is made from a mixture of flax and jute. Jute insulation is excellent for caulking wooden houses.

Linen batting is similar in characteristics to jute fabric, but is slightly cheaper. Linen has become one of the most used fabrics for filling seams due to its unique characteristics. Firstly, it is able to regulate moisture exchange, accumulating and then releasing vapor. This provides protection against fungus and insect pests. Secondly, the material is completely natural, it is made from flax and has a natural grayish color.

Insulation sheets are cut into strips of the required width and length with a small margin. It is laid in several layers depending on the density of the material and the width of the seam. The edges of the strip are carefully tucked in and also driven into the gap. A well-placed seal provides the house with not only high thermal insulation properties, but also good sound insulation.

Caulking tools

Tools for caulking walls are called caulking tools and are several types of metal or pointed wooden spatulas, as well as a wooden mallet. The wooden tool is used for straight seams; it is made from soft wood. Metal caulks are intricately curved and are used for corner joints. They hit the blade with a mallet, driving the required amount of compaction into the gap between the logs. The process continues until the elastic resistance of the material becomes noticeable.

Caulking technology

During the caulking process, the gaps between logs or beams are filled with sealing material. Work begins from the lower crown and moves around the perimeter of the house. At the same time, first the walls are caulked from the outside, and then from the inside. Particular care is taken to fill the gaps in the area of the corner connection of logs or beams. Caulking is often done in two stages: during the assembly of the log house and after its shrinkage. The first stage is called roughing and is performed to reduce the amount of work at the final stage. The second caulking is done more carefully, sometimes the crown joints are even disassembled in order to more carefully lay it with sealing material.

You can caulk the walls “in a stretch” or “in a set”. The first method is applicable to long and relatively narrow seams: fill the seam with insulation tapes, and at the end the entire layer is tacked with a tightly rolled roller. The caulking “set” is carried out in wide slots: the material is wound in a special way into a strand, from which loops are “set” for driving into the groove.

Despite the fact that the principle of caulking is extremely simple, the quality of the work performed directly depends on the experience and skill of the performer. A balance must be strictly maintained between the density of the material being driven into the seam and the effectiveness of the insulation achieved. In rare cases, too active clogging of the seal can even lead to the log slipping and the risk of destruction of the log house. If the technology is followed, then upon completion of the work the log house will “grow” by about 10-15 cm and will become much warmer.

Caulked seams retain heat well, but do not look very aesthetically pleasing. To make them attractive, they are decorated with jute rope or other materials. This additional finishing slightly increases the cost of caulking.

Cost of caulking

The price of caulking in the price lists of construction companies is most often indicated per linear meter. It is higher for houses made of logs and slightly lower for timber buildings. The final amount may differ slightly from the calculated amount depending on the characteristics of a particular object: the quality of its assembly, the type of corner joints, etc.

Why choose jute

The reason for the popularity of jute fibers is their low price and good performance; on the Russian market, jute competes with traditional Russian flax. When the question arises: how to caulk a house made of timber, preference is increasingly given to jute. Cottages, economy class residential buildings, bathhouses and outbuildings are insulated using jute.

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

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

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

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

Tool for caulking at home

Before you get to work, you need to make a special tool - a caulk. It's easy to do with an axe, but I usually use a jigsaw whenever possible because I'm always afraid of chopping something off myself. Caulking is done, if you don’t rush, in exactly 10 minutes.

Here is the sequence of actions.

1. Take some scrap of board 25 mm thick and cut out the following blank:

The length of the workpiece is such that it is comfortable to hold in your hands.

2. We cut or trim it as follows:

3. Sharpen the caulk with an ax so that it forms a wedge and makes it convenient to push the tow between the logs.

How to caulk a log house

During the assembly of the log house, the sealing material is spread as evenly as possible, always with fibers across the groove, while it is necessary that the thickness of the insulation is about a centimeter, and its ends protrude on both sides by at least 50 mm. A layer of insulation up to 4.5 cm thick can be laid over doorways and window frames. After completing the installation of the log house, the material is rolled into a roller and driven into the gap using a special blade - caulk

Particular attention is paid to corner connections

It is recommended to make the blade for this procedure from the same type of wood as the log house, since when made from a harder material during operation, it will inevitably damage the logs, forming chips, scratches and dents.

There are two ways of caulking: “stretched” and “set”.

Extended caulk is used, as a rule, as the first caulk when assembling a log house.

Caulk “as a set” is used for additional processing of seams after the house has given the necessary shrinkage, or to eliminate wide cracks and grooves.

It must be remembered that caulking is a very complex technological operation that requires special professional skills and extensive work experience, therefore this procedure must be performed exclusively by highly qualified craftsmen - caulkers.

Despite the presence of a number of advantages, such as environmental friendliness, good thermal insulation and reliable wind protection of a wooden building, caulking a log house also has some disadvantages.

Watch a video on how to caulk a log house with jute:
And the last thing we will look at is caulking a log house with sealant. A sealing cord is first laid in the gap, and then the entire gap is blown out with foam from a mounting gun. You can also seal large cracks in logs.

Then the seams that have not yet dried are moistened with water and carefully smoothed with a brush or spatula. All excess foam is removed.

Materials for caulking

Experts call traditional sphagnum moss the best and unsurpassed in terms of durability, insulating qualities and healing effects on residents. Other natural materials are also good for caulking - tow, jute, linen and felt (wool) insulation.

Today there is a huge selection of various polymer sealants that have the undeniable properties of excellent adhesion, strength, elasticity and durability. But for caulking a natural log house, it would be more accurate to focus on the use of natural materials.

In addition, polymer synthetics as sealants are not so durable compared to natural materials. The moss in the inter-crown joints of very old, up to a hundred years old, log houses when they are dismantled is surprising, it is so whole, dense and clean. The ability of sphagnum to quickly absorb moisture, retain it without releasing it to the wood, and just as quickly release this moisture into the air when air humidity fluctuates is amazing. Moss lives and breathes together with the log house, preserving the warmth in the house, the health of the log house, and at the same time the health of the residents. It’s not for nothing that sphagnum has been used for caulking since ancient times, and in our time this material is by no means archaic; on the contrary, moss insulation between the crowns of a log house is a sign of an eco-house.

In addition to being ecologically impeccable, moss has antiseptic qualities and prevents the development of fungus and mold between the crowns of the log house.

Polymer synthetics are lagging behind here too. Excellent adhesion to wood does not prevent moisture from penetrating into the joints, but it does prevent the escape of this moisture. This may cause the wood to rot. And over time, the elastic and adhesive properties of sealants decrease, and the process of infection of logs can accelerate.

Of all the representatives of the extensive family of mosses, two are used for caulking - swamp white sphagnum moss and green moss called cuckoo flax. Moss must also be laid when cutting a log house, laying it between the crowns, while the moss is moistened and evenly distributed over the logs of the log house, and the moss stems are placed in the transverse direction and the ends of the stems are left outside the walls by 100-150 mm, for caulking. The thickness of the moss layer should be at least 100 mm. Moss can be bought or harvested. Collecting moss is easy, but cleaning it thoroughly takes time. Soil, leaves, twigs and twigs cannot be left in the future insulation. drying moss is not very difficult, due to the properties of moss it can dry in the sun, in the shade, and even in rainy weather under a canopy.

Jute or jute fiber is very popular and in demand for insulating log houses. This material does not grow here, and therefore is not cheap. It is characterized by excellent heat protection, biostability and excellent “breathes” between the crowns, comparable in quality to sphagnum. Birds do not value jute and do not use it for nests.

An excellent insulation material that has no less ancient history than moss - natural sheep's wool. Excellent energy-saving properties, the ability to densely fill even thin cracks, high elasticity and elastic properties of wool fibers make wool the champion of caulking. Another excellent property is that when caulking seams with sheep wool, as a rule, there is no need for repeated caulking, due to the elastic properties of wool. The downside is that this insulation is expensive.

The traditional tools for caulking are considered to be a caulk - this is what the device is called - and also a mallet, a wooden or rubber hammer with a wide striker part. Various spatulas that are easy to use, often steel, are also used. You can use any convenient tool if the main task is to fill the inter-crown seam evenly and as densely as possible. For speed, small-scale mechanization tools are also used - hammer drills or electric chisels. In the right hands, any tool can be used, but the impact force of a hammer drill must be contained. Torn and twisted insulation strips and damaged logs as a result of hammering with a hammer drill are a very poor caulking method and a guarantee of future problems with the log house.

You can use an electric chisel to fill the seam, but you will still have to roll the tape by hand. Manual caulking was and remains a long and painstaking process, but the result is worth it - a warm and healthy log house.

Insulation technology for log walls

From ancient times to this day, two main technologies have been used to insulate wooden walls.

Stretching - used mainly for caulking narrow cracks:

a strand is formed from the selected insulation, placed in the slot and pushed through with a spatula, leaving an edge of the material about 5 cm long outside;
then a thin roll is rolled out of the insulation, which is wrapped into the left free edge of the insulation and carefully, using a chisel, hammered into the groove.

Included in the set - used for caulking large grooves and cracks between logs:

the sealant is twisted into long strands up to 15 mm thick and wound into balls;
then it is carefully unwound, while simultaneously hammering the material into the cracks using a caulking chisel;
if the gaps have different sizes, then for larger ones the required thickness of the insulation is gained by twisting it into loops.

Tools for work:

caulks (they are different: type-setting, curved, broken);
wooden mallet or rubber mallet with a wide head.

Caulking tools have a steel blade that must be soft and smooth, otherwise it may damage the seal.

Work order:

The caulking process itself begins from the bottom, from the very bottom crown and continues upward. It must be taken into account that caulking the seams changes the height of the log house.
One seam must be caulked along the entire perimeter of the log house, first from the outside, then from the inside. This will avoid distortions in the walls of the house.
Then the next highest seam is processed. And so on until the very top.

It is forbidden to caulk individual walls; this may cause the wall to deviate from the vertical.

As you can see, the process of caulking a log house is not that complicated, but it requires great care and careful execution of all operations. Then your home will be protected from atmospheric influences for many years, and the facades of the house will take on a finished look.

Preparatory work

Since jute is a durable material, there may be no need for re-caulking, which saves time and money. But still, in order for a self-made caulking to last a long time and reliably seal your home, it must be installed correctly. To do this, you need to prepare in advance and prepare your tools. You should choose jute of a width that matches the width of the gaps between the logs.

To prevent the logs from rotting and collapsing, the cracks should be properly treated before caulking. For this purpose, special wood antiseptics are used. The sealant should be placed only in dry cracks. It is best to carry out caulking in the summer, warm dry spring or autumn. The air temperature should not be below +10° C, there should be no rain. Too hot weather is also not suitable, as the logs dry out unnecessarily, which can result in overuse of jute.

Jute materials are easily torn by hand. Without using any special means, you can install the seal yourself quickly and easily. But such a finish will not have a completely aesthetic appearance, so it cannot be used for walls that carry a decorative load. To make caulked walls look neater, the pieces of insulation need to be identical and have smooth edges. To do this, the jute must be cut with a sharp knife or scissors. Therefore, the tools should be sharpened in advance.

You need to squeeze the sealant into the gap carefully, using a special metal caulk, which visually resembles a small chisel. If one is not available, it can be replaced with a thin chisel. To drive the seal into the gap, you will also need a hammer and a rubber mallet. If the gaps are small, then you can use a jute rope of small diameter. If the rope is narrow and the gaps are large, then it is better to fold it several times.

Tow

This material is waste generated after the primary processing of natural fibers.

The logs are caulked with jute, hemp and flax tow. The properties and quality of such material are determined by the raw materials, the length of the fibers and the level of their purification. During production, tow is pressed into blocks. To use it, you need to pull a strip of material from the block, twist it into a rope and place it in the seam.

Although, it is easier to use tow sold in rolls.

In general, tow is not very convenient to work with, since it is very difficult to get an even seam. When caulking a log house, due to the high rigidity of the material, it is difficult to obtain a tight seam from the first approach. We have to resort to a repeat process.

If you decide how to properly caulk a bathhouse by choosing between moss and jute tow, then you can confidently say that it is better to choose moss, since it does not harbor fungus and bacteria.

What to caulk with?

Of course, you cannot caulk cracks in a bathhouse with ordinary cotton wool - this will require more suitable, ideally natural, materials. An alternative to them may be industrial sealants.

Moss

Moss is considered to be the most commonly used material for these purposes. Despite the fact that today a sufficient amount of materials has appeared, this plant still remains in a leading position due to its outstanding characteristics. The environmentally friendly material has a significant antibacterial effect and provides high-quality thermal insulation. It is not prone to rotting and can be used for a long time. It is also worth mentioning that microorganisms do not multiply in moss.

However, the material has a number of disadvantages. Considerable time will have to be devoted to selecting and collecting moss. Samples that are too wet will contribute to the rotting of the structure, and samples that are too dry will break and crumble. We must not forget that buying moss costs a significant amount. Natural material is not particularly easy to lay out, so it is better to combine it with tow.

Before starting work, the moss must first be left to dry in the fresh air, turning regularly. Then the material is soaked for 30-60 minutes, wrung out and then laid out in a layer and leveled so that the ends of the fragment hang from both ends of the frame. When all the logs are laid, the excess fibers will have to be shortened, or wrapped and tucked back into the cracks. Subsequent stages of work will occur only after 6 months and 1.5 years, and the entire process will be a three-stage process.

Jute

Recently, jute fiber has been used quite often to caulk cracks in a building. This material promotes high-quality thermal insulation due to the presence of natural binding resins and does not get wet at all, even in conditions of high humidity. It is worth noting that fiber rarely deteriorates due to rotting. The environmentally friendly material fits well between the logs, simplifying the entire caulking task.

It is customary to distinguish three main varieties of jute.

Jute tow is formed by combing the fiber and aligning it in the required direction. The material retains its properties, but its rigidity and low density complicate the caulking process. Since the fiber dries out, it has to be laid out several times. There is also a high probability that the tow may simply be stolen for birds’ nests.
Jute felt is formed by combining 90% jute and 10% flax fibers. The flexible material is easier to work with than tow, but its short length can be a problem, causing it to fall out. To prevent this situation, it is better to select fibers that are at least 20 millimeters in length. It is for jute felt that moths appear.
Flax-jute looks like a ribbon created by combining soft flax and hard jute fibers. It is easy to use, but is prone to rot and requires pest control. In its properties it resembles flax wool.

Tow

Tow is the waste remaining after the first stage of processing of jute fiber, hemp or flax. This material is very inconvenient to work with; in addition, it is very often subject to rotting and transformation into dust, which has to be cleaned out and caulked again. However, this fiber is an environmentally friendly material with thermal insulation and antibacterial characteristics. The higher the quality of the initially processed material, the better the quality of the tow. These fibers are cheap and available. Tow is sold in blocks and rolls. During caulking, the required amount of material is removed from the packaging, which is twisted into a rope and used to fill the seam.

Disadvantages of caulk

1. Caulk work is accompanied by quite a lot of noise, since in order to properly compact the insulation in the crack, it is necessary to hit the blade with a special wooden hammer, so this procedure will inevitably interfere with a quiet everyday life.

2. It is also necessary to take into account that the sealing material will be pulled out of the seams by birds, which use it to build nests. Often, to distract birds from the structure, small pieces of insulation are placed nearby as bait.

3. Insects and various microorganisms can grow in the thickness of the sealing material over time; in the process of life, they destroy the insulation, which leads to the loss of its physical properties and spillage from the gaps. To avoid this problem, wooden houses are treated with special protective impregnations and coatings.

The cost of caulking a log house is an expensive job, and since this procedure must be carried out many times to obtain an optimal result, it becomes clear that the costs of high-quality processing of the structure will be considerable. You also need to remember that if the building requires primary or repeated caulking of the log house, the prices for the materials used and the work of the caulkers will depend on the design features of the house and the corner connections of the logs.

Another feature of caulking is that caulked seams, as a rule, do not look very attractive, so they often require additional decorative finishing. Linen tow, woolen felt and moss were traditionally used as sealing materials, which are distinguished by their reliability, availability and good thermal insulation. However, recently more modern tape insulation materials based on natural flax and jute fibers have appeared. Their main advantage is that when using them there is no need for double caulking, which significantly reduces construction time. That is why today the most popular is jute insulation, characterized by high strength, low hygroscopicity and excellent spinning properties.

The caulking of a log house, carried out in compliance with all technological rules, allows you to reliably insulate the structure and ensure its moisture and wind protection for many years.

Varieties of jute release forms and their application

Jute is available in the form of cord, rope, twine, rope or tape. The thickness and width of the material may vary. It is easy to caulk thin tow or jute in the form of a rope into old cracked logs with your own hands. Jute tape makes it easier to seal gaps around doors and windows. It is also used to fill gaps in building materials. A seal made from a harness and cord looks the most aesthetically pleasing and does not require additional processing. Thin cords and ropes are suitable for finishing not only walls, but also floors and ceilings.

The main producers of jute are India, China and Kazakhstan. The highest quality and most expensive product is produced in India. The width of the jute and its thickness directly affect its cost. The sealant is sold in the form of skeins and bobbins, which are gradually unwound during use. Working with natural material is quick, easy and does not leave excess debris, like synthetic sealants. Sealing materials made of jute reliably adhere to other building materials.

Jute tow has good elasticity, so it easily takes the shape of the surrounding space. Material made from wood fibers withstands frost and heat and does not crumble. The properties of jute made from wood fibers are similar to wood. Such material can be subjected to various treatments. It reacts to impregnation with resins and staining in the same way as wood: it does not dry out or crumble, and does not allow heat and moisture to pass through.

Caulking rules

Caulking of a log house is carried out in two stages - immediately after construction and after some time, when shrinkage occurs. Primary (or rough) caulking can be carried out in two ways: with laying insulation during the process of assembling the walls or performing one-time work upon completion of construction.

Each log house requires high-quality caulking, which is performed in two stages

1 way

Lay the bottom row of logs on the base.

Then the insulation is spread on top so that the ends of the material hang evenly on both sides. Next, lay the second crown, and again a layer of insulation. This is repeated until the very top of the log house. After all work on the construction of the log house is completed and the roof is installed, the protruding ends of the seal are driven into the gaps between the beams using caulking.

Method 2

Caulking begins after installation of the roofing system on the log house. Insulation (preferably tape) is applied to the seam of the bottom row and, using a tool, is pushed into the gaps between the logs along the entire length, leaving hanging edges 5-7 cm wide. Then these edges are folded in, formed into a roller and hammered inside the seam. Repeat the procedure in the next row and so on until the top of the structure.

The second stage of caulking is carried out after shrinkage of the log house - after 1-2 years. The selected insulation is applied to the cracks between the crowns and driven tightly inside. You should always start work from the bottom row, and be sure to do it along the perimeter of the log house.

Insulation padding

You cannot caulk one wall first, then the second, and so on. In addition, each row is caulked both from the outside and from the inside to avoid distortions in the structure. The insulation raises the frame by 5-10 cm, and its uneven distribution contributes to the vertical deviation of the walls. In some cases, the log house is caulked for the third time - 5-6 years after construction. During this time, the wood completely shrinks and new gaps form.

Gaps between crowns

There are two ways of caulking - “set” and “stretched”. The first is used to eliminate wide gaps between logs, the second is usually used during primary caulking, when the gaps are still narrow.

To work, you need tools - a set of caulking tools, a road worker and a mallet. As a rule, metal caulks are used, although many craftsmen make them themselves from hardwood.

Advice from the experts

The walls of a house made of edged timber do not always have an attractive appearance; it is almost impossible to lay insulation between the crowns without unevenness, so it will not be possible to caulk the frame “string by thread”. You can decorate the facade using jute rope, which is laid over a layer of inter-crown insulation; the rope is secured with clapboard nails.
After finishing caulking, it is advisable to treat the crown gaps with an antiseptic; the domestic drug “Neomid” is an effective remedy. The product provides long-term protection of insulation made from natural materials from rotting, fungus and insects. It has a liquid consistency and is applied with a brush.
If the frame is sanded after shrinkage, finishing caulk is carried out last - after sanding of the walls is completed.

How to make a log house correctly

Unfortunately, without this additional procedure it is impossible to achieve a normal microclimate in a wooden house.

Our ancestors came up with an effective way to deal with uninvited “fickle” guests. To do this, write down the rope with your own hands: after the trailer structure in the house, the room is tightly packed with insulating material on a natural basis (for example, moss, hemp, yarn).

Then the wooden cottage was completely protected from the weather, and the thermally insulated seams adequately played the role of a protective “jacket”.

Until now, the ancient technology is still in process, only the tools and materials for the work have been improved.

Builders systematized this process by developing two algorithms for constructing poles.

Do-it-yourself log caulking technology

The technology for caulking a log house with your own hands is quite complex, although you can’t tell it from the outside. As we said earlier, when caulking a log house, the structure becomes 7-10 cm higher, so you need to caulk it evenly and correctly.

You should know that no finishing activities should be carried out before caulking the log house, because... during lifting of the structure they will be immediately damaged.

Proper caulking of a log house involves insulating the inter-crown space in tiers (from lower to upper). First, we caulk the very bottom joint (between the first and second crown). This must be done along the perimeter, starting from one corner and ending with it. As soon as the tier is insulated, you need to move to the overlying crown.

It should be noted that experienced builders can straighten a skewed frame using only caulking.

When caulking a log house, it is necessary to carefully hammer in the insulation at the corners, because These nodes need this the most (due to the presence of locks and complex grooves).

There are two ways to caulk a log house with your own hands: “stretch” and “set”. The first method is used if the gaps between the rims are small, respectively, the second is intended for wide gaps. Let's take a closer look at each of the methods.

Extended log caulk

To caulk a log house "expanded" you will need a strand of insulating material for the length of the entire crack. First, you need to tamp one side of the strand into the gap, then bend the other side (as shown in the picture) and carefully hammer it in with a breaking or type-setting caulk.

Log caulking “set”

This method of caulking a log house with your own hands requires much more insulation material, but it insulates the bathhouse from the log house more efficiently. The caulking technology proceeds differently: a strand with a thickness of at least 15 mm is prepared. Next, you need to gather the strands into the loops and hammer each loop into the gap one by one (so that the strand goes across the gap, as shown in the picture). It is necessary to hammer the strand using a breaking caulk, tamping the material from above and then from below. After the strand is completely hammered into the cracks, it is recommended to make a final compaction using a road builder.

Summarizing the above

The caulking of the bathhouse, according to all the rules, retains thermal energy in the bathhouse and significantly extends its service life.

Improperly carried out work on insulating a building will lead to its rapid cooling, rotting of the log house and the breeding of pests in it. Remodeling takes a lot of time, effort and material costs. Properly performed work will help increase the service life of the bathhouse. The erected structure will delight you for many years with its warmth, power and solidity.

Proper insulation of a bathhouse can be the key to its good quality and optimal heat retention. You can caulk the walls of such a building yourself, thereby significantly saving money

It is important to know well the basic rules of the process. Typically, such work extends significantly over a long period.

Note that the basic process of insulating a bathhouse has become a tradition; it is no different from the methods that were used by our distant ancestors during the reign of kings and monarchs. The process of caulking a bathhouse seems to be a complex and painstaking process that requires a lot of time and effort. Its implementation must be approached only with certain knowledge and practical work skills.
