Do-it-yourself caulking of a log house, technology nuances. Log caulking technology - which is better to do it yourself or order it, price analysis

To get rid of the gaps between the crowns and close the cracks formed during the shrinkage of the log house, apply caulk: this is the only way to retain heat inside the log house. For work you can use various materials, but the technology is the same. How to caulk a log house correctly? What's best 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 disadvantages.

Natural

These include moss, tow, jute, flax wool, hemp and others.

Moss

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

Tow

The technology using tow is considered one of the most complex. As the log house dries out, the material will become damp, which is why it will begin to rot over time. Therefore, after drying the house or bathhouse old tow cleaned and then caulked the log house again.

Jute

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

There are several types of material:

Jute tow. When producing 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 ready material not very convenient for work: rigid, and at the same time not too dense. The process of caulking when using the material becomes more complicated - the work has to be carried out in several stages (during the initial laying, the required degree of density cannot be achieved).
Flax-jute. A mixed material consisting of equal amounts of flax and jute fibers. It is popular among builders, but needs protection from insects: before use it is treated with anti-moth and anti-rot agents.
Jute felt. The material, 90% jute and the remaining 10% flax fiber, has the density necessary for work, but at the same time remains flexible. The ease of use of felt makes it optimal choice. When purchasing a material, you should choose one whose fibers are longer than 2 cm - it is more elastic and flexible. The only drawback is that it can be damaged by moths, so before laying the felt, it is treated with a special protective impregnation.

Lnovatin

Insect repellent material is processed chemicals, therefore it cannot be called environmentally friendly. The service life of the insulation is up to 3 years; it is attached to the frame using construction stapler.

Synthetic

Application ready-made compositions– 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 product, it is used together with a natural one (for example, a cord). First, the cord is sealed into the gap, and sealant is applied on top, leveling the layer with a scalpel spatula.

Among the disadvantages of sealants:

A number of synthetic products are destroyed under the influence of sunlight - over time, they begin to crumble and fall out. To protect the substance from damage, strips are installed on the seams, which protect the sealant from ultraviolet radiation.
Some compositions, after drying, harden into a dense solid mass, due to which the wood, which contracts and expands depending on humidity and air temperature, begins to collapse. It is recommended to use only flexible sealants.

Methods for caulking the walls of a house or bathhouse

Caulking and insulation of a log house can be done using two methods:

Into the set. Suitable for wide crevices. For work, use jute, tow or hemp. The selected material is divided into strands and wound into a ball.
Stretch. In this case, the heat-insulating material is divided into strips and driven into the cracks.

General rules

The initial caulking of a timber house is carried out approximately 6 months after assembly. During this period, most of the moisture contained in the timber will disappear, cracks will appear on the wood, and cracks will appear in the structure itself.

The next time the work will need to be carried out another year. By this point, the structure will have completely settled, 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 technology is not followed, the need to eliminate cracks may arise annually. To ensure that the caulking of a timber house is done correctly, it is worth watching a video with advice from experienced craftsmen.

Work starts from the bottom. Consistently caulk lower crown along the entire perimeter from the outside, then inside the log house. After that, they move on to the next one, acting in the same way.
Typically, the largest cracks form at the corners, so caulk in these places should be especially careful.
First, the material is fixed in the crack over an area of about 1 m, then the hanging parts are folded in and tucked inside. Using a mallet, the insulation is firmly hammered into the gap until the material begins to spring back. When everything is done, move on to the next section.

Caulk with moss

To work you will need:

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

Work order:

Add 200 g of soap and 0.5 liters of oil to a bucket of water. Mix thoroughly.
Place dry moss in the prepared liquid. Wet fibers will become elastic.
Take a strand of material, twist it into a roller, and insert it into the slot. They compact well.
Using a spatula and mallet, firmly hammer the insulation into the gap.

For primary caulk When making a log house using moss, it is recommended to use the “stretch” method, all subsequent ones – the “set” method.

Using tow

Over time, insects may infest this type of insulation, and in order to protect it, the tow should be treated with a disinfectant.

You need to prepare:

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

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

Formalin is diluted with water to obtain a disinfectant solution.
All the prepared tow is placed in it and left for half an hour.
Having taken out and squeezed out the material, they drive in the tow, divided into strips, using the “stretch” method. The insulation is compacted using a spatula and a mallet to achieve maximum packing density.

Caulk with jute

This material is laid using the “set” method.

Depending on what type of material is chosen, you will need:

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

Work order:

The tow is soaked in a formaldehyde solution.
The material is rolled into strands and filled into the cracks of the lower crown.
Using a tool, push in the hanging edges.
Using a groove, level the position of the insulation layer.

Important! When processing the area around the chimney pipe, you need to leave about 3 cm of the surface untouched.

Caulking with sealant

Caulk timber house using sealant is the fastest way. To work, you will need the synthetic material itself, a cord for filling the cracks, a special spatula for smoothing the seams (you can use a narrow spatula), and a mounting gun.

Log buildings have their origins from ancient times. Wood is the most warm material for building a house or bathhouse. In addition, it is natural, safe and environmentally friendly.

But after erecting the structure, it is necessary to perform another very important procedure - caulk log house. Why do you need to do this?

firstly, caulk insulates the house (bathhouse) properly;
secondly, it fills the gaps between the logs, that is, it creates comfort and warmth in your home in any frost;
thirdly, it prevents the penetration of dampness and moisture into the structure.

In the old days, log houses were caulked with moss. In those days it was the most reliable and available material in order to insulate your home.

IN modern world the range of insulation materials that can be used for caulking a log house has expanded significantly. This includes the following materials:

Red moss. It was used in the old days, but even today it remains an excellent insulation material for log houses. It is good because it does not rot, and also has excellent antibacterial qualities. But there are also several negative aspects: if it is exposed to excessive moisture, the wood will rot. And when it dries out, it breaks and crumbles.
Tow. It is very good for caulking a log house because it is an excellent material for thermal insulation. Consists of hemp and flax waste. Tow, like moss, prevents rotting.
Felt. It can't be called the best option for caulking. Because it has the least strength and the highest probability of rotting. It also needs to be soaked special means to prevent the appearance of moths, which are likely to settle in the layers of felt.
Jute. A material that can confidently be called one of the best for caulking. It is highly durable, dense, rot and moth resistant. Has low hygroscopicity. Thanks to jute caulking, an optimal microclimate will be maintained in the house. It does not accumulate moisture, but releases it when the wood dries out.

But jute should not be confused with jute fiber. They are completely different in appearance, price and quality. The jute tape is soft to the touch and very pliable. It is convenient to use it for caulking around doors and windows. Sometimes it is laid on damp beams.

Jute ribbons can be found in skeins of different thicknesses and widths. Most craftsmen prefer jute caulk because it is the lightest and clean way insulation of the log house. And since it is laid directly on the frame, the work proceeds much faster.

Lnovatin. This modern material, made from linen threads or fibers without the use of weaving. Its characteristics are very similar to jute tape, but a little more rigid in structure.

Caulking is often done with your own hands. This is done in 2-3 stages. And this process can be considered very important in the construction of a house or bathhouse.

The first time caulking is done immediately after the house is assembled. But for the seams to be airtight, the first insulation is not enough. After a short amount of time log structure dries out and sags. As a result, new holes appear. IN winter time heat escapes through them, and the outside or inside of the building becomes covered with frost. And excess moisture is not good for a wooden structure.

Therefore, 1-1.5 years after the timber has dried out and sagged, it is necessary to re-caulk it. The third time the log house is caulked immediately before finishing the walls, when the house is completely dry and settled, after about 3 years.

How to caulk a log house

Caulking of a log house can be done in two ways: stretched and set.

Caulking in a stretch. If narrow gaps predominate on the log house, then it is better in this case to use the stretching method. It is done like this: cover the gap with a bunch of tow, and stuff it inside with a caulking chisel until the entire space is completely filled. This leaves an edge of four to five centimeters free. The roller rolled up from tow is wrapped with the free edge. When intertwined, it is hammered between the crowns with a hammer and caulk. The quality of the work done can be checked by lightly pulling the roller. If it doesn't stretch out, it means the job was done well. If it pulls out, then the gap is not filled enough.
Caulking set. If there are large and wide gaps in the structure, the “set” method is used. Its essence is to fill the cracks with tow, long bunches wound into a skein. In this case, the thickness of the loop is approximately the same size as the gap. The sealant is first filled with the top of the gap using caulk, and then everything is leveled using a “road builder”.

It must be remembered that caulking must be carried out correctly, starting from the lowest crown along the entire perimeter, gradually rising upward. And this procedure is carried out in parallel outside and inside. Because if you caulk one wall, the structure may become deformed. The same thing will happen if you caulk only the outside.

It is also necessary to remember that you should not carry out any finishing works inside until caulking is completed.

Particular attention should be paid to caulking cracks in the corners of the house.

If you carefully select the material for caulking and carry out all the work correctly, then your log house will serve you for a long time and will make you happy. Happy construction!

Caulking technology

Simply laying a frame when building a bathhouse is not enough - you will definitely need to caulk the bathhouse, that is, close the existing cracks and cracks formed after the wood has dried out.

This article will discuss how to caulk a bathhouse.

The caulking of the bathhouse frame is needed so that it loses a minimum of heat. It is very important to use a well-prepared log house, lay it correctly and do not forget to install inter-crown insulation.

What to choose as insulation - moss, tow or jute - is up to the owner to decide, but it must be present.

The insulation is placed in two layers as follows:

on the lower crown so that the edges of the insulation extend beyond the edges of the bowl by 30-50 mm, while the width of the insulation is determined by 50-100 mm more than the width of the bowl;
the second layer of insulation is placed in the bowl of the upper crown, while its edges should also protrude by 30-50 mm.

It is worth keeping in mind that when laying moss or tow, tapping such material is not required.

If you hit it with a hammer or an ax handle, the moss fibers are torn, and dents appear on the surface of the wood, which after some time can cause the appearance of rotting zones. It is recommended to compact the fibers only by pressing with the palm of your hand. Excess elements in the moss simply need to be removed.

If, when deciding on the best way to caulk the log house of a bathhouse, the choice fell on tape insulation, then you can fasten it with a construction stapler.

In this case, it is important what to pierce the bathhouse with, since it can cause harm to the material.

Damage to the wood from the stapler will be minor, but this will allow the material to be firmly fixed. It is best to lay out insulated crowns together so that the log can be taken from both sides and slowly lowered without damaging the insulation.

How can you caulk a log house?

There are natural materials for caulking and artificial ones.

The first include tow, hemp, jute, moss, and so on. The latter include industrial sealants. Sealants are easier to work with and apply quickly. As a rule, in order to reduce their consumption, a cord is laid in the inter-crown gap, and the sealant, which is distributed with a special spatula before hardening, is applied on top of it.

However, sealants have a number of disadvantages:

Some brands are afraid of exposure ultraviolet rays– this leads to their destruction. This disadvantage can be eliminated by hiding the sealant seams under the strips.
Some of them, after hardening, create a monolithic material that interferes with the process of expansion or contraction of wood, for example, due to weather, which can lead to the destruction of nearby fibers.
To prevent this fact, it is better to purchase elastic sealants.

You can learn more about how to operate the sealant by watching the available video material. A simple tablespoon is perfect for distributing the sealing agent.

If, when determining how to caulk a bathhouse, you chose a sealant, then carefully study the instructions and make sure that it can be used with exactly the type of wood from which your log house is made, that it is suitable for your region, and also has all the necessary characteristics.

It is advisable to use a synthetic sealant for a log bathhouse if it is used to close caulked cracks. After double caulking the log house with tow, moss or jute, wait until the log house finally settles and reaches working dimensions.

Each of the materials of natural origin for caulking has its own positive and negative qualities, and preparatory measures are required in any case.

Moss

Moss is considered the most common, time-tested material for caulking. It has been used for hundreds of years. Currently, there are many other materials, but they all have slightly worse characteristics. True, new materials are easier to operate, and they also have such positive qualities as antibacterial properties and special resistance to rotting.

Before caulking a log bathhouse with moss, it must be dried and soaked right before use. This action will give the moss fibers elasticity. The moss is laid out in a layer and leveled so that its ends hang down on both sides of the beam. After all the logs have been laid out, the excess moss fibers are shortened, and what remains is wrapped and tucked into the cracks.

Thus, the first stage of caulking the log house is carried out. Further stages of caulking will be continued after a year and a half.

Jute

IN Lately Builders are increasingly asking the question of how to caulk a bathhouse with jute. Given that we mean rolled material. Jute fiber has excellent thermal insulation properties and contains natural binding resins. Jute is practically not afraid of moisture, and very rarely becomes unusable due to rotting.

Even in conditions of high humidity it does not get wet.

Jute comes in several varieties:

Jute tow.
During production of this material the fibers are not torn, but combed, aligning them in in the right direction. This preparation of the material allows it not to lose all its properties. However, jute is not very convenient for caulking, because it is hard and has a low density; caulking has to be done several times due to the material drying out, the impossibility of obtaining a tight seam the first time and the birds pulling it apart for nests.
Jute felt.
This material is based on 90% torn jute fiber, and is supplemented with 10% long flax fibers. The result was dense and flexible material, which is much easier to work with. But if it has a short fiber length, it may get confused and fall out. When choosing jute, you should choose a material with a fiber length of at least 20 mm to obtain maximum elasticity. Short material will not have the necessary properties, it will either fall out or the wind will blow it away.

Another disadvantage is the fact that moths can appear in it. In this regard, it is recommended to impregnate such material before installation with a composition against moths and against rotting.
Flax-jute. It is a composite tape material, half of the volume of which is soft flax fibers, and the rest is hard jute fibers.
This material is of interest to many builders, but it also has disadvantages, such as a tendency to rot and moth damage. That is, like the previous material, this one also needs to be treated with mixtures against rotting and pests.

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.

At what stage can you start caulking a bathhouse?

If the frame was laid on moss or tow, pieces of material of various lengths protrude between the crowns.

In this case, you can begin the initial caulking: trim off the excess fibers, and hide the rest in the seams. You should be careful and take your time, adhering to the rules of caulking. If the log house was laid on tape insulation, then further operations are not necessary.

The first caulking is carried out about 6 months after the construction of the log house walls. During this period, almost all the moisture will leave the logs, new mother-in-law will be visible, and most of the crowns and corners will shrink.

After this, you can begin installing doors and windows.

Further caulking is carried out after 12 months.

During this time, the log house will be completely stable, so that all found defects can be eliminated. Based on the selected material and the quality of the work performed, you may need a new caulk in about 5 years. Sometimes, due to negligent construction work or, if insulation was not laid between the crowns, the caulking has to be repeated several more times, every year.

How to calculate tow for a bathhouse

Before caulking a bathhouse with tow, you should decide on the required amount. Tow compresses quite well, so it is consumed quite heavily. Perhaps no one can say the exact number. This is because there are a lot of nuances that influence this: the material of the log house, what grooves are cut into them.

If the grooves were made manually, then, often, the consumption of tow will be large.

In addition, consumption increases if a sanded log was used rather than a rounded one. Less material will be used for the timber, although in this case its quantity will be determined by the parameters of the timber, the depth and number of cracks that appeared during the drying process.

Caulking technology

Before caulking the log house of a bathhouse, you need to study the basic rules of this process.

In fact, caulking a log house is quite easy, but it takes a lot of time, and you also need to be patient. For a bathhouse with dimensions of 5x4 m, one person will need about 10 days, spending 7-8 hours daily.

At the same time, you should not overdo it when laying insulation, since this fact leads to the fact that the log house becomes 15 cm or more higher.

The basic rules for caulking include the following points:

First of all, they start with the lower crown, moving along the entire perimeter.
First, the outer part of the building is processed, after which they move on to the process of caulking from the inside. Only after this can you move on to the next crown.
During caulking Special attention It is worth paying attention to the corners, because in such places, as a rule, the largest gaps are located.
If this is the original caulking, then first of all the sagging material is picked up, folded and pushed into the gap.
What is the best way to caulk a log house?

You can resort to any tool as needed. The process is carried out in stages - after the meter is processed, they move on to the next section.
On the same area you can use a caulk, a hammer or a wooden mallet; the latter is much easier to work with. The caulk is beaten until it begins to spring back.
Following the compaction process, cracks may appear into which fragments of insulation are inserted. If tow was used, a rope of a certain thickness is rolled up from it or a fragment of a specific length is disconnected from the tape, which is also driven in with caulk and a mallet until a springy effect is achieved. This operation is repeated until all the cracks are filled, after which you can move on to a new area.

Like any other part of construction work, caulking requires certain skills from the master.

Based on the fact that there will be quite a lot of such procedures, after some time you will definitely develop them. Over time, along with which you gain experience, you will notice more and more new inaccuracies that were made on initial stages works

You can eliminate them without much difficulty, bringing the work to almost perfection. Actually, those who do nothing make no mistakes, so caulking a log house with the proper quality is possible even without sufficient experience.

As for caulking a log house made of rounded logs, there are advantages and disadvantages. It would seem that the log house is also made of wood, what differences could there be other than its picturesque appearance and simplicity in the design process. The fact is that rounded logs of log houses are more susceptible to the influence of environmental factors than log houses made from ordinary logs, since the structure and integrity of the logs are damaged.

The technology for caulking log houses made of rounded logs does not differ significantly from the insulation of conventional log houses with tow, but there are still some differences:

Since rounded logs are almost ideally shaped, there are small gaps between them, unlike conventional logs.
For a log house made from rounded logs, you will need much less insulation for caulking, which is an undeniable advantage.
The process of caulking log cabins made from rounded logs is more complex in contrast to caulking conventional log cabins, since the gaps between the logs are smaller and thinner and they need to be well insulated by carefully laying them with tarred oakum or modern acrylic-rubber-based sealant.
In the process of caulking a log house from rounded logs, it is necessary to have great experience in this type of work, since, taking into account the minimum dimensions of the seams, there is a high risk of overstuffing interventional insulation, and this may lead to distortion of the frame.
Therefore, it is best to invite a professional to do this work. After carrying out high-quality caulking of a log house made of rounded logs, the insulation roller - jute tape or flax wool - should resemble punching with flax rope or jute rope.

When caulking, special attention should be paid to the joints between rounded logs, since the most vulnerable places in such log houses are the joints between logs in corner locks.

If they are not properly caulked, in winter they may cause big problems associated with heat loss.

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 thermal insulation properties, but for full experience warmth the village must work hard.

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

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 of the room is tightly packed 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”.

Still ancient technology is still a work in progress, only the tools and materials for the job have been improved.

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

Do you always need to remove the frame?

Wooden house construction is now much simpler because workers do not perform manual initial processing of the logs and do not receive sanded, dry and adapted dimensions of the building material. Whereas an agricultural family previously took several years to build on a log plan, a modern, elegant eco-home takes literally a few weeks to grow.

Let's look at all the ways to build a wooden house in a wooden house and indicate whether each of them requires manure.

Windshield wipers made from hand magazines

This is an old way to build a wooden house, which is still popular among enthusiastic fans of antiquity.

Its complexity lies in the long, problematic selection of approximately identical thick trees and subsequent manual adjustment of the required size.

Not many people choose this kind of "hard work" but in the end they get exact copy ancient Russian farm house.

Craftsmen involved in logging must have a good knowledge of all carpentry work.

Traditionally, on the outside of the house, the facade remained wavy, but for interior walls the beams were processed so that the rooms had smooth smooth surfaces.

During construction, workers are forced to constantly compensate for curtain curtain distortion due to the non-flying shapes of the workpiece. A number of repairs and features form a natural material that results in the interior allowing for increased shrinkage (up to 25%!), so they must be particularly precise with insulating gaps.

Konopatka's diary is carried out twice and, if possible, even three times: the first time - immediately after the construction of another - 1-1.5 years after the preservation of the field building, and the third - 3 years after the completion of construction.

Round ray logs

The sticks used during operation are installed at the factory.

On lathes, the workpieces are secured using a fastening mechanism and then crushed by a treadmill to a certain depth. In addition to automatic fitting, the material is carefully dried and treated with a protective impregnation (against insects, fire and water).

It gives full round logs the same diameter in which the assembled grooves are often cut at the factory.

Assemble items easily, there is no need to constantly adjust the crown to each other, so that workers involved in assembling the house may not be fully proficient in carpentry skills.

Handbag advocates have a rounded diary that has lost its geography. This means that, depending on the perfectly smooth workpiece, you may not be able to tell where north is, the more stress-resistant side and some of the stronger layers of wood are lost.

But these shortcomings are not so painful in reputation building materials, since they provide a record speed of construction of a wooden house.

This hive is carried out only 1-1.5 years after its conservation, since the building is subject to slight shrinkage (6-8%).

Working slots are carefully covered thermal insulation material, but recycling can be avoided entirely (depending on the quality of the substrate used).

Log house made of laminated veneer

Special squares are used to build a wooden house square shape, consisting of glued lamellas of the same thickness (2-5 pieces). The material is carefully dried and processed during the production process protective equipment and adhesives with properties that must meet strict environmental requirements (DIN, EN, 204) and water resistance (level D4).

At the factory, one side of the beam is attached to a sealing surface, and builders only need to ensure that the joints of the logs are sealed.

This significantly speeds up the process of assembling a wooden house, and low-skilled workers can also participate in construction.

Advice from the master!

Due to small shrinkage values (up to 2%), hulls with glued beams should not get stuck. The building can be immediately occupied and the walls, ceilings and floors can be decorated with decorative protective coatings.

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

What, why, when

A bathhouse or house that was built from rounded logs or logs 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. This phenomenon occurs when some of the moisture is lost and drying out occurs. During this process, loose connections of material may appear where previously everything seemed 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 cracks to prevent drafts and reduce heat loss. Caulking should be done after complete shrinkage, which occurs within 6–7 months.

The better

In order to carry out the log sealing process as efficiently as possible, you need to acquire not only good tool, but also suitable material, and also have an idea of how to use them correctly. From the devices we will need:

Caulk. This is a small device that in appearance resembles a chisel or chisel. Typically, to carry out tasks efficiently, you will need at least two types. One of them is called typesetting. The width of its blade can reach 10 cm. Thanks to it, you can move faster large plots. The second will be smaller, about 2-3 cm. It will be needed during compaction corner connections. Skillful craftsmen They use a curved tool, which allows them to do the work much better, but requires special skill.
Material that will be used to fill the gaps. Previously, only natural fibers were used for these purposes. Today, synthetic materials have already been invented, as well as various sealants.
Hammer. In this case, you can use any one you have on the farm, but it’s better if it’s a small sledgehammer.

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

Moss

Red marsh moss is used for these purposes. 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 the best way. You can’t lay it too wet, you need to let it dry a little.

If this is not done, this may lead to the joints beginning to rot and the structure becoming unusable. But it is also not recommended to lay it dry. In this state, it will crumble easily, and subsequently will not be able to seal the seams hermetically. Before driving it, it is necessary to carry out certain processing. A water-based solution (10 l) is 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 this, the moss is soaked and laid to drain a little. To make the roller easier to form, 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 craftsmen are not very fond of this fiber. The fact is that it is quite difficult to work with him. Also, over time, the tow becomes unusable, which will force you to take out its remains and do everything again. Before laying it, it will be necessary to treat it with a special substance that will serve as an antiseptic and also repel insects that can feed on both the fibers themselves and cause harm to the wood.

An excellent material that, like moss, allows the tree to breathe. He is good filter, which does not allow odors to pass through. 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 moths love to feast on felt. Before caulking, it is treated with special compounds that repel this insect.

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

One of the best materials. It not only perfectly fills cracks, but also protects the inter-crown space from moisture penetration. Birds don't use it to build their nests, so you don't have to worry about them pecking it off. It is made from wood from the linden family. It is usually imported from other countries. The material is soft and flexible.

Jute rope. In addition to its direct purpose, such caulking serves as a decorative finish.

Sealant

This 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.

What to choose is a personal decision for each individual. Everything will depend on the budget, as well as the availability of a particular material in a particular area. But it’s better not to skimp on material.

Technology

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

Stretch. This type got its name due to the fact that the material stretches along the entire seam and the fibers intertwine with each other. It is usually used for primary caulking. After the construction of the log house, the cracks are still quite small, so there is no point in filling 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. Using a tool, it is pushed into the cracks. After this, the ends that are left hanging are tucked into a roller and compacted tightly into the seam.
Included in the set. This method is used after the log house has shrunk and the cracks have become more noticeable. To do this, you will need to collect all the fibers in a heap and make ropes from 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 cracks are not the same everywhere.

After the distribution of roll material, the process of sealing seams was greatly simplified. Primary laying is usually done immediately when laying the logs. To do this, a roll of material is placed on the lunar recess and secured using a construction stapler. Next, the log is placed in its place. There is no need to carry out additional work after complete assembly.

During initial 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 laid. One should go next to the other, and the edges should 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 takes place at least six months later, is not the last. In about 4-5 years, when the building has finally settled down, it will be necessary to treat the seams again. You can follow the following sequence:

We clean the seams from debris and material that has come out or worn out. You can use a vacuum cleaner to make the task easier.
Caulking needs to be done one by one, not one by one. Those. You need to move around the circumference of each row. This is important so that distortion does not occur and the building is not damaged.
You should start with outside, and then move inside the building.
You need to unwind the tape. Its length should be 15–20 cm greater than the length of the wall. This is important, because during the compaction process folds are formed, which will be used for this reserve.
Now it is important to carefully tuck one of the edges of the tape into the gap to secure it.
Next, using a caulk and a hammer, we make a compaction. To do this, we lift the hanging end, tuck it in and tamp it down. This operation must be completed in several passes. You shouldn’t try to hammer everything in at once, as this can lead to misalignment 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 to not allow air from the street to pass through.
We repeat the operation from the inside.
We move from the lower (flashing) crown to the upper one. Perhaps in the upper part it will be enough to just carefully tuck the material in without much effort so as not to interfere with further shrinkage.

You need to be careful not to overdo the layering. During caulking, the frame is raised. If you make the backing too thick, it can cause the lift to exceed the size of one log. The consequence may be that the dowels will not hold up and the beams will fall out.

Insulation with sealant is much easier. To do this, purchase a special lace of a suitable diameter. It is usually made from synthetic materials. It fits effortlessly into the seam to cover the gap. After this, 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 on the sunny side, because... The manufacturer usually advises avoiding direct sunlight until completely dry.

Sealant is also used after using natural materials. It helps protect the seal from pests and animals. Inside the house, instead of sealant, you can use twine of sufficient diameter to decorate 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.

Caulk with moss

In caulking with moss, the main thing is no longer compliance with technological subtleties - in this regard, it is a lot easier than caulking fibrous materials– and the procurement of material. More precisely, purchasing. Forest and swamp building moss goes on sale, but self-harvesting of tree moss is possible only in certain places very remote from civilization, and self-harvesting of bog moss in most developed countries is prohibited and prosecuted by law: in last decades identified exclusively important role swamps as moisture accumulators and regulators of natural processes. In addition, mosses actively accumulate many useful and harmful microelements; swamp moss is a natural filter for radionuclides. By caulking with moss collected yourself, you risk not only infecting the frame with rot, mold and pests, but also yourself and your loved ones, which is no better.

The best moss for caulking is bog sphagnum, or cuckoo flax, pos. 1 in Fig: it never wakes up in buildings and releases substances that protect wood from damage. But it is impossible to caulk with bright green fresh sphagnum (item 2) - on the contrary, it will overheat and ruin the frame. You need to caulk with moss (both swamp and forest), dried until it withers without rotting, pos. 3. This moss is sold in bags (item 4). It must be stored in them until use, not allowing it to dry out completely: moss that is still slightly alive is suitable for caulking. Dried gray or brown building moss (item 5) is not caulk, but insulation material. By the way, very good.

Note: It is impossible to caulk with rock and ground moss - particles of the substrate with germs of wood pests will certainly remain in it.

Procedure for caulking with moss

They caulk with moss before winter. In the spring, when it gets warm but not dry yet, the hanging festoons are checked (see below) and the green ones are plucked out. Then the scallops are tapped into the grooves. It is very important to prevent the caulk from drying out: if the moss begins to crumble under the caulking tool, the entire caulk will never be intact, and every 2-5 years you will have to re-caulk, and the entire log house will not stand as long as it can. A year later, the building is checked and, if it is split, a secondary caulk is carried out with the same (!) moss.

Sphagnum moss is laid out in the grooves when assembling the log house as a mountain (item 1 in the figure below), because It cakes heavily under pressure. The festoons of bog moss should hang abundantly from the grooves, pos. 2. Immediately after assembling the frame, moss is added to the remaining cracks (shown by arrows in position 2), tamping with a scythe on top wooden caulk. Quite easily reviving tree moss, on the contrary, is laid out sparingly but tightly so that there are no empty cracks, pos. 3. Its festoons should protrude from the grooves of the assembled frame by approx. half the palm of your hand, but not hanging down, pos. 4. Hanging ones (shown by an arrow in position 4) are cut off.

Instead of moss

In coastal areas you can find durable log buildings, caulked instead of moss with damask - sea grass eelgrass or eelgrass thrown ashore by storms. Kamka also good insulation and in this capacity it is now sold dried, but caulk can only be done with damp, fresh stone. But caulking with damask turns out to be excellent: it releases salts into the tree, making it unsuitable for pests, and releases iodine into the air in the room. Which, as is known, among other beneficial properties, helps remove cumulative poisons and radionuclides from the body. They caulk with damask like moss, with some differences: they take it apart into flat strands and lay them out in the grooves of the log house in a herringbone pattern without gaps so that the ends hang down half a log. Upon completion of the assembly of the log house, the ends are tapped into the grooves with wooden caulk.

Synthetics and sealants

Synthetic caulking is used in combination with rough jute tape, or, for “aesthetics,” with twisted white jute rope. The rough tape is placed in the grooves of the log house under caulking with sealants without wings, flush with the edges of the groove. If the logs have a Finnish groove, then the edges of the tape should lie exactly on the longitudinal cuts in the log under the edge protrusions of the groove of the upper log.

Sealants for wood are produced in chemically neutral polyurethane: silicone is less compatible with wood in terms of mechanical and physico-chemical properties (in particular, in terms of the coefficient thermal expansion TKR), and is destroyed under the influence of even very weak acids. In turn, the silicone solvent - acetic acid - spoils the wood, so do not try to replace special sealants for wood with ordinary construction ones. Synthetics are used to caulk mainly log houses made of laminated logs and timber - their estimated service life is the same as that of glue joints of laminated lumber.

Caulking with sealants is done quickly and simply: the initial composition is squeezed out of the tube into the groove, pos. 1 in Fig.. When it has set, the seams are puttied on top with a finishing compound to match the wood, pos. 2.:

There is also an “ultra-modern” method of caulking log houses built without rough caulking at all: cuts are made along the seams, strands of self-expanding polyethylene foam are inserted into them and sealed with wood-like sealant, pos. 3. In essence, this is no longer caulking, because This method is suitable for buildings made of lumber without shaped grooves, assembled on dowels and impregnated with water repellents (water-repellent impregnations). In addition, it is only suitable for selected materials chamber drying, completely dried out and shriveled. And then what will happen with warping from moisture during operation - we’ll wait and see: in practice, “caulk-free caulking” has so far been used for no more than 10-12 years.

Let's return to caulking, which is still caulking, albeit synthetic. Finishing compounds darken when dry, so they are selected to match the wood using test strokes on the container. But in the light, the finishing synthetic caulk fades and the walls of the log house take on the appearance shown in pos. 4. Some people, since such “decoration” cannot be avoided, order caulking seams to be glued or filled with white twisted cord. How much this adds “aesthetics and respect” to the building is a matter of taste of the owner. And there is no arguing about tastes. Moreover, about the tastes of people who believe that natural wood needs additional “improvement”.

It is much more practical to use synthetic caulk to seal gaping cracks in logs, pos. 5 in Fig. On top of the sealant, the cracks are filled with any wood putty for exterior use, and the entire structure is rejuvenated. The putty has to be renewed every 2-3 years - it also fades in the light - but this doesn’t last long, it’s not difficult and inexpensive.

The final touch - sanding

Caulking has not yet completed the construction of the log house until it is ready for flooring, installation attic floor, roofs, installation of windows, doors, partitions, for finishing and equipment - the log house is desirable, but the inside must be sanded. Especially – chopped from wild log, debarked by hand.

Sanding a frame with sandpaper is extremely time-consuming, tedious, and this damages the outer most resistant layers of the wood. The log house is sanded manually using a universal grinder with nylon brushes. Worse - grinder with them; drive is too powerful. But the main thing here is still brushes for sanding wood, see video review:

Video: review of nylon brushes for sanding logs

Sanding a log frame with a brush is actually a controversial issue: the brush removes the bead of caulk, see figure..

After installing the log house, there is still a lot of work to be done, including caulking the bathhouse. This must be done to close the gaps between the timber or logs and to insulate the walls. Without proper caulking, the bathhouse will be ventilated, and the heat will quickly leave the room. In addition, logs or beams will soon become unusable, crack and become damp.

You can easily caulk a bathhouse with your own hands, since this process is not very complicated. But it is important to choose the right materials and carefully follow the technology. Let's find out how to properly and what is the best way to caulk a bathhouse made of logs or timber.

Features of bath caulk

It is important to perform this procedure correctly, otherwise installation errors will cause the walls to warp or cause serious cracks and cracks. This simple process, but quite long and monotonous. Therefore, you need to be patient! Caulking is done six months after the installation of the log house, when most of the shrinkage of the tree has passed. After this caulking, you can already install windows and doors.

If a second caulk is needed, the procedure is performed a year after the first (1.5 years after installation of the log house). Depending on the quality of work and material, another caulk may be required after 4-5 years. In any case, this procedure is very important for wooden buildings.

Bath caulk performs the following useful functions:

Reliably closes cracks and gaps in wooden walls between crowns and ceilings, logs and crowns, in window and door frames;
Eliminates cracks in wooden log house, which are formed during the shrinkage process. Caulking prevents the growth and appearance of new cracks;
Enhances the thermal insulation qualities of wood and retains heat indoors for a long time, which is especially important for a bathhouse;
Protects the room from wind penetration, internal wooden walls from the negative effects of moisture;
Seals cracks in an already built house or bathhouse.

Among the materials for caulking, there are natural and synthetic types. Natural jute, tow and moss - traditional means which have been used for a long time. Industrial sealants are used from modern artificial materials. Each product has its pros and cons, and which one to choose is up to each owner to decide. Also among the tools for caulking you will need a hammer, a 20 mm chisel and a rubber mallet.

Natural materials for caulking

The oldest and most proven method is to caulk a bathhouse or house with moss. This is an environmentally friendly and safe material that will preserve natural properties and aesthetics wooden structure. It effectively resists the negative effects of bacteria and prevents the formation of fungus or mold, quickly absorbs moisture and does not rot. However, it is not very convenient to use. Moss is optimal for baths and sealing cracks in a wooden house.

Processing with jute is also good for baths, as this environmentally friendly material saves natural properties and tree safety. This fiber is distinguished by high strength, thermal insulation, resistance to moisture and decay. Roll material with an even structure it is easy to lay between the crowns. However, jute often becomes a breeding ground for moths, so it is recommended to treat the material with a moth repellent before use.

Tow represents waste after primary processing natural fiber jute, flax or hemp. This is a very difficult and inconvenient material to work with. In addition, when a log house shrinks, it gains moisture, rots and turns into dust.

As a result, this rot has to be cleaned out and the bathhouse frame caulked again. Among the advantages of tow, we note the environmental friendliness and safety of the fiber, high antibacterial and thermal insulation properties. However, due to its complexity and fragility, tow is not recommended for caulking baths or at home.

Sealants

Modern sealants have long filled the construction market. These are quick, convenient and easy to use products that are well suited for independent work. However, in this case, it is important to choose high-quality sealants from a reliable manufacturer, since some do not tolerate exposure to sunlight and wind.

As a result they lose beneficial features and are blown out. Additionally, some types of sealants can damage the wood fibers when they dry. To avoid this, use elastic products (acrylic) that contract or expand with the wood.

At the same time, sealants have a large number of advantages, including not only easy and quick installation. Such products are characterized by high thermal insulation qualities, resistance to moisture, cold and temperature changes. In particular demand today warm seam using acrylic sealants. This product contains rubber, which gives elasticity and prevents small hidden cracks from cracking further.

Acrylic sealants are safe and environmentally friendly, making them ideal for processing wooden bath or at home. They do not emit toxic substances and allow the wood to “breathe”. These products can withstand high temperatures, do not have an unpleasant odor, and are distinguished by quick and easy finishing. They do not allow wood to rot and have wide choose color range. Read more about acrylic sealants and “warm joint” technology.

Features of caulking using different materials

If you are using moss, the material must first be completely dried and re-moistened before use. To do this, soak the material for 30-60 minutes and squeeze thoroughly. The soaked moss is laid out between the crowns in an even layer so that the ends of the material stick out on both sides of the log or timber. After this, the too protruding and long parts of the material are trimmed and tucked into the cracks of the log house. After a year, re-caulk must be done.

When using tow, it is better to choose rolled tow, as it is easier to use. If you choose tow in blocks, a strip of material is pulled out of the block and a rope is twisted, which is then placed into the seam. Take jute with a fiber length of more than two centimeters. Short fibers fall out easily and are blown out.

Caulk natural materials carried out using two methods. The “stretching” method assumes that the material is divided into separate strips and placed in the gaps between the rims. The insulation remaining outside is rolled into a roller and driven into the groove. The “set” method means that the fibers are separated into strands and wound into a ball, and then pushed into the spaces between the logs or beams.

When choosing a sealant, first lay a heat-insulating cord made of polyethylene or jute fiber in the cracks. This will reduce the consumption of the main product and increase the thermal insulation properties of wood. And then sealant is applied over the cord in a wet state with a layer thickness of 4-6 mm.

Then the layer is leveled with a spatula or spatula, and the remains are cleaned with a rag. The sealant is left to dry for two days, while it is important to protect the seam from moisture. Detailed instructions Directions for use can be found on the packaging of each product.

Bath caulking technology

Before starting work, logs or beams are cleaned of dust and dirt. Can be closed wooden surface construction tape or masking tape so that the insulation does not get on the walls of the log house;
Start with the bottom crown and move around the perimeter of the bathhouse, first from the outside, then work the bottom crown around the perimeter inside. Only then move on to the next crown! Each crown should be caulked in turn, without skipping rows;
Pay special attention to the corners of the bathhouse, as in these places there are a large number of cracks and large gaps;
During the process, carefully monitor the evenness of the walls of the log house and check how the insulation fits. The material should lie tightly, evenly and not form bubbles;
Do not use under any circumstances polyurethane foam for caulking a wooden bathhouse or home! It violates the naturalness and environmental friendliness of materials, reduces the service life of insulation;
After completing the work, check the quality of the work. To do this, try removing the material or piercing it with a sharp object. If you can remove an entire strip or pass a sharp tool through the insulation, the work was not done well.

When laying insulation, it is very important to follow the technology, otherwise incorrect actions will not allow you to get maximum efficiency from caulking. The room will be ventilated, and the caulking itself will have to be done again every two to three years. In addition, mistakes can lead to skewed walls, rotting of logs or beams, and lumber falling out of locks!
