The better to caulk a bath from a bar. Caulking baths: technology and selection of material. Sealants - modern technologies

logs are laid with insulating material. It can be hemp, felt, tow or dried moss.

In order to seal the junction of the logs even better, caulking is carried out, driving in the sealing material with the help of special tools.

What is the best way to caulk a log house?

You can caulk, as we said a little higher, with felt, moss, tow or hemp. Choose the material that is more accessible to you.

It should be remembered that each of them requires preliminary preparation.

If you decide to punch a bath with moss, as it has been done for centuries in Russia, then the moss must first be dried. Wet moss can lead to rotting of log logs, and too dry (overdried) will crumble.

If you opted for felt, then do not forget to soak it with a solution of formalin or any other substance that prevents moth breeding. Otherwise, you run the risk of soon finding a lot of moth larvae eating felt with pleasure.

The same applies to the package.
After impregnation, felt or tow should be dried.

V Lately many people prefer to use materials such as jute and lnovatin when building a bath.

Jute is a heater which is made from a jute tree (linden family). His distinctive features are high strength and very low hygroscopicity. Even at very high relative humidity, jute insulation remains almost dry.

Lnovatin has recently received no less popularity. This is a material obtained from flax production waste and produced in the form of tapes, which are convenient to use in construction.

Logging tools

In order to make caulking more convenient, special caulks have long been used.

Most often, the following are used: a type-setting caulk, a crooked caulk, a road builder, a broken caulk and a mallet, which is used to strike caulks.

You can see what they look like in the picture below.

Where to start caulking a log house?

Like any of the works in the construction of a bath, caulking also has its own nuances that you should know before you start caulking a log house with your own hands.

As a result of caulking, each of the walls becomes slightly higher (from 5 to 15 cm). Therefore, it is impossible to caulk the walls in turn, so that the log house does not warp.

Caulking starts from the bottom groove between the logs and goes along the perimeter of the entire bath. After that, they go to the groove, which is higher, and also caulk it around the entire perimeter, after which they go higher. So all the walls will rise evenly and the frame will not warp.

If by this time the oven has already been installed, then in order not to damage chimney, you should temporarily free up some free space around it in the ceiling and roof of the bath.

Methods for caulking a log house

When caulking a log house, they most often caulk “in set” and “stretched”.

Caulker "in set"

"Vnabor" usually caulk wide grooves and slots. To do this, the sealing material is twisted into long strands 15-20 mm thick and wound into a ball.

Filling the free space between the logs, the material is compacted with caulks.

First, along the upper edge, then along the lower, after which they are passed by the road builder.

Caulker "stretched"

Insulating material with this type of caulking is applied to the groove or slot and pushed inward by hands, after which its edges are tucked in and clogged with force with caulking inside.

Not everyone knows how to properly caulk a log house, and therefore the performance of insulation work sometimes leads to a distortion of the house (in the worst case) or simply to rotting of wood and insulation (at best).

About how to properly caulk log cabins from moss video and general recommendations for other types of insulation in our material below.

Materials for caulking a log house

Caulk wooden frame can various materials. Fortunately, the construction market today offers a wide selection of them from natural to synthetic and semi-synthetic. The most popular are the following types:

building moss. May be called "sphagnum" or "cuckoo flax". This type of insulation was used by architects back in ancient Russia. The qualities of moss as a heater are priceless and undeniable. Sphagnum is highly resistant to moisture. It seems to shrink with the tree in case of waterlogging of the latter and simply takes all the moisture into itself. In addition, moss is of no interest to birds, moths and other insects. And this means that all the material for the caulking will remain in the place that the master determines for him. Moss "sphagnum" and "cuckoo flax" does not burn, does not rot and is an excellent natural antiseptic for wood for many years.

Important: you can buy building moss in any volume at specialized points of sale.

Construction tow. This type of material also works well in tandem with wood when caulking walls. Produce tow from the remnants of flax and hemp grass. Tow is also a natural material that protects wood from moisture and cold.
jute fiber in the form of a tape - advanced natural-type materials for caulking walls. Jute is made from a shrub that belongs to the linden family. And linden, as you know, copes well with cold and moisture. Jute is able to somewhat moisten the log when it dries out excessively, but it does not take moisture from the tree when the humidity in the house is 80%. It is convenient to lay a jute tape between the crowns, and also stuff it into the cracks when re-insulating the house.
Lnovatin. They produce insulation from flax fiber in the form of a wide tape. By their own technical specifications lnovatin is similar to jute. It is convenient in laying between the crowns and when caulking "in a stretch".
Felt. Unsuccessful type of insulation for wooden house. Felt is prone to rotting between logs, and if excessive moisture gets on the walls, the felt will not only lose its insulating qualities, but also spoil the tree from the inside.

Tool to get the job done

To properly caulk a log house, you need to use special tools. Otherwise, the insulation will lie superficially in the cracks, which will lead to the formation of cold bridges. Most professionals use special caulks made of steel or metal. The first one is better. You can also make wooden caulks from dense woods - beech, walnut, oak. At the same time, it is desirable that the tool has a rubberized handle for ease of work.

Important: the caulking tool should not have a sharp blade, otherwise the insulation may be damaged during caulking. For the same reason, you should avoid notches on the surface of the tool. The insulation in this case clings to the teeth and breaks.

The main type of tools for caulking:

Stacked caulk. It is a flat kind of chisel with a blade width of 10x0.6 cm. It is used for stuffing seams between logs with insulation.
Crooked caulk. The same chisel, but curved. It is used for caulking the corners of the house and rounded cracks. The width of the blade in this case is half that of a type-setting caulk.
Caulker "Roader". It has a fork-shaped shape and is used for caulking cracks using the “stretching” method. The blade here has parameters of 170x15 mm. Depending on the width of the gap, you can use a wide, medium or narrow caulk.
The caulk is broken. It has a wedge-shaped blade 30-35 mm wide. Such a tool is used to expand narrow gaps and fill them with insulation.
A mallet is used to help all types of tools. With the help of such a rubber hammer, the seal is pushed into the slots.

Work performance technology

In order for a log house to be insulated with high quality, the insulation must be laid in several stages. First, roll insulation or building moss is laid out between the crowns in such a way that it protrudes 5-6 cm beyond the edges of the log. In this case, a tape insulation such as jute or flax fiber is fixed to the tree with a construction stapler. By the way, you can do the same with moss.

After the house settles and sits down, new cracks form. It is through them that heat loss will occur. In addition, the heat leaving the house, in contact with wood and low temperatures on the street will form perspiration (moisture). That, in turn, is transformed into frost, which will destroy the log. That is why additional caulking of new slots and packing of a peeking seal between the crowns is required.

The third caulk can be done after 2-3 years, when the house is completely seated and all possible cracks will be open to the master.

Caulking methods

Warming "stretching"

This method involves filling narrow cracks and gaps. It is good for caulking houses from rounded logs, since the gaps here are minimal. At the same time, you should be careful with the caulk of such a log house. There is a risk of overfilling the slots, which will lead to distortion of the crowns, and, accordingly, the walls.

So, stretching insulation is performed in this way:

As soon as the edge of the insulation 5 cm long remains, a new bundle of insulation is taken and its edge is woven with the remaining end.
The resulting plexus is hammered into the slot and in this way they continue to caulk all the gaps.

Important: the quality of the caulk can be checked by pulling on the remaining end of the insulation. If the material comes out freely from the gap, the job has not been done correctly. If the insulation remains in the gap, then everything is done soundly.

Caulker "in a set"

This method is used to fill large cracks. Here it is necessary to wind the insulation into a skein. Then, loops are made from the resulting fiber and the slots are stuffed with them. Moreover, first they caulk the upper part of the gap with a stuffing tool, and then hammer the loops into lower part clearance using the road builder tool. It is worth knowing that the thickness of the insulation loop must correspond to the thickness of the existing gap in the log house.

Important: when working with a mallet, it is worth remembering that there should be one hammer blow per blade width. Do not be too zealous, otherwise there is a risk of overfilling the cracks, which will lead to a warp of the house.

There is also a number general requirements, which should be observed when caulking a log house. By following them, you can avoid blunders in work:

So, you need to start re-caulking at home from the lower rims, because when you stuff the insulation in the crack, the house will rise by 5-15 cm.
It is necessary to fill the gaps alternately from the outside and from the inside of the house. That is, first fill the gap lower crown outside, and then go inside the log house and fill the gaps of the same crown from the inside. This technology will help maintain the evenness of the walls of the house.
Best used for caulking natural heaters. Synthetics blocks the breath of the tree.
If moss is used for caulking, then it should be treated with a special solution of soap and oil in a ratio of 200:500, mixed with a bucket of water.
Warming of the house must be carried out in dry weather at a temperature of + 10- + 20 degrees Celsius.
In addition, a lack of insulation is just as bad as its bust. It is necessary to strictly monitor the amount of fiber in the loops so that their width matches the width of the gaps.

Remember, properly done work is a guarantee of warm and cozy home even in severe frosts.

Caulker with moss

In caulking with moss, the main thing is no longer the observance of technological subtleties - in this respect it is much simpler than caulking with fibrous materials - but the preparation of material. Or rather, a purchase. 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 marsh moss in most developed countries is prohibited and prosecuted by law: in recent decades, the extremely important role of swamps as moisture accumulators and regulators has been revealed. natural processes. In addition, mosses actively accumulate a lot of both useful and harmful microelements; swamp moss is a natural filter of radionuclides. Caulking with moss collected on your own, you risk not only infecting the log house with rot, mold and pests, but also yourself and your loved ones are no better.

The best moss for caulking is swamp sphagnum, or cuckoo flax, pos. 1 in rice: 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 (pos. 2) - by overheating, on the contrary, it will ruin the log house. You need to caulk with moss (both marsh and forest), dried to wilting without charm, pos. 3. This moss is sold in bags (pos. 4). In them, it must be stored until use, not allowing complete drying: moss, still a little alive, is suitable for caulking. Overdried gray or brown building moss (pos. 5) is not caulked, but insulation material. By the way, very good.

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

The order of caulking with moss

Moss is caulked before winter. In the spring, when the heat comes, but dryness has not yet come, they check the hanging scallops (see below) and pluck out the green ones. Then the scallops are knocked into the grooves. At the same time, it is very important to prevent the caulking from drying out: if the moss began to crumble under the caulking tool, the whole caulking will never be whole, and once every 2-5 years you will have to make repeated caulking, and the whole log house will not stand idle 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.

Moss-sphagnum is laid out in grooves when assembling a log house with a mountain (pos. 1 in the figure below), because. it shrinks under pressure. Swamp moss scallops should hang abundantly from the grooves, pos. 2. Immediately after assembling the log house, moss is added to the remaining slots (shown by arrows in pos. 2), knocking down with an oblique wooden caulk. Quite easily reviving tree moss, on the contrary, is laid out sparingly, but tightly so that there are no empty slots, pos. 3. His scallops should protrude from the grooves assembled log approx. half a palm, but do not hang down, pos. 4. Hanging (shown by the arrow in pos. 4) are cut off.

instead of moss

In coastal areas, you can find durable log buildings, caulked instead of moss with damask - sea grass thrown ashore by storms or eelgrass. Kamka also good insulation and in this capacity it now goes on sale dried, but it can only be caulked with wet fresh damask. But caulking with damask turns out to be excellent: it releases salts into the tree, making it unsuitable for pest settlement, and iodine into the air of the room. Which, as you know, among others useful properties, contributes to the excretion of cumulative poisons and radionuclides from the body. Caulked with damask like moss, with some differences: it is disassembled into flat strands and laid out in the grooves of the log house with a herringbone without gaps so that the ends hang down half a log. Upon completion of the assembly of the log house, the ends are knocked into the grooves with a wooden caulk.

Synthetics and sealants

Synthetic caulks are used in combination with a black jute ribbon, or, for "aesthetics", with a twisted white jute cord. The rough tape is placed in the grooves of the log house for caulking with sealants without wings flush with the edges of the groove. If logs with Finnish groove, then the edges of the tape must exactly lie on the longitudinal cuts in the log under the edge protrusions of the groove of the upper log.

Sealants for wood are produced chemically neutral polyurethane: silicone in terms of mechanical and physico-chemical properties is worse matched with wood (in particular, in terms of thermal expansion coefficient 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 wood sealants with ordinary building ones. Synthetics are mainly used for caulking log cabins made of glued logs and timber - their estimated service life is the same as that of glue joints of re-glued lumber.

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

There is also an “ultra-modern” way of caulking log cabins, built without any rough caulking: cuts are made along the seams, bundles of self-expanding polyethylene foam are put into them and sealed with sealant under a tree, pos. 3. In essence, this is no longer a caulk, because. this method is suitable for structures made of lumber without shaped grooves, assembled on dowels and impregnated with water repellents (water-repellent impregnations). In addition, it is suitable only for selected materials of chamber drying, completely shrunken and shriveled. And what will happen later with warping from moisture during operation - let's wait and see: in practice, "caulking-free caulking" has so far been used for no more than 10-12 years.

Let's get back to caulking, which is still caulking, albeit synthetic. The finishing compositions darken when dried, so that they are selected to match the tree according to trial smears on the container. But in the light, the finishing synthetic caulk burns out and the walls of the log house take on the form shown in pos. 4. Someone, since such a “decoration” cannot be avoided, orders gluing or clogging caulk seams with a white twisted cord. How much this adds to the structure of "aesthetics and respect" is a matter of taste of the owner. And they don't argue about tastes. Moreover, about the tastes of people who believe that natural wood in need of some additional refinement.

Much more practical is the use of synthetic caulking for sealing gaping cracks in logs, pos. 5 in fig. On top of the sealant, the cracks are puttied with any wood putty for outdoor work, and the whole structure is rejuvenated. Putty has to be renewed every 2-3 years - it also burns out in the light - but this is not long, easy and inexpensive.

The final touch - polishing

Caulking is not yet completing the construction of the log house until it is ready for flooring, installation attic floor, roofs, installation of windows, doors, partitions, for decoration and equipment - a log house is desirable, but it is necessary to grind inside. Especially - chopped from wild log debarked by hand.

Grinding a log house with sandpaper is extremely long, tiring, and this damages the outer most resistant layers of wood. The log house is polished by manual universal grinder with nylon brushes. Worse - a grinder with them; the drive is too powerful. But the main thing here is still brushes for grinding wood, see the video review:

Video: an overview of nylon brushes for sanding a log house

Grinding a log house with a brush is actually a moot point: the brush removes the caulking roller, see Fig..

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

What, why, when

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

The better

In order to produce the process of sealing the log cabin as efficiently as possible, it is necessary 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 need:

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

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

moss

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

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

tow

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

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

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

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

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

Sealant

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

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

Technology

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

Stretching. This type got its name due to the fact that the material is stretched along the entire seam and the fibers are intertwined. Usually it is used for primary caulking. After the construction of the log house, the cracks are still quite small, so 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. With the help of a tool, it is pushed into the cracks. After that, the ends that remain hanging are tucked into a roller and tightly rammed into the seam.
To the set. This method is used after the log house has shrunk and the cracks have become more visible. To do this, you will need to collect all the fibers in a heap and make ropes out of them, which are then wound into a ball. Moreover, the thickness of such a rope will have to be calculated separately for each seam, because the gaps are not the same everywhere.

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

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

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

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

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

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

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

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

Video

This video shows the process of caulking with acrylic sealants:

Built from a bar, laid, the roof is blocked, and the windows are inserted - it's time to insulate the log house. Slots can be traditionally caulked - with moss, modern material- jute or tow. How to do it right and what to prefer - read the article and look at the video.

How to choose the right material for insulation. Which is better

Answer unequivocally, the more correct to caulk wooden bath, almost impossible. Each material has pros and cons, so you need to familiarize yourself with their characteristics, and only then make a final decision.

Moss. You can buy it at a hardware store or collect it yourself in the forest. Warming with its help was practiced by our grandfathers, and their experience can certainly be trusted. True, now this material is far from being a favorite, because there are new ones that are more convenient to use. Nevertheless, the advantages of moss include:

environmental friendliness;
medicinal properties;
profitability;
resistance to decay;
resistance to temperature changes.

Of the minuses, it is necessary to highlight:

exposure to moisture;
fragility;
high fire hazard;
brittleness when dried;
the complexity of the heating process.

Tow. It comes in hemp, jute or linen and is sold in rolls and square blocks. The first option is more convenient, because individual strips need to be pulled out of the blocks, twisted and laid in a slot. Among the advantages of the material:

naturalness;
low cost.

Perhaps this is where the visible advantages of tow end. Minuses:

difficulty in use. If over time you decide to remove the tow from the seams, you are tormented;
attraction for mice and moths.

Advice. Tow is a kind of alternative to moss, which many experts advise to give preference to if you choose only between these two options.

Felt. It can be natural or with the addition of artificial fibers. The first one is preferable because it is not so flammable (it burns worse). Advantages of felt:

environmental friendliness;
convenience in work.

susceptibility to moisture and decay;
high price;
high risk of moths. In addition, often felt becomes the object of encroachment by mice and birds, which pick it out of the seams.

Lnovatin and flax fiber. Made from flax waste. Batting is a material with the addition of artificial fibers. It is more convenient in laying, as it is produced in the form of tapes. Flax fiber is similar to tow, so working with it requires patience. Materials do not absorb moisture and are resistant to decay. You can distinguish one from the other by color: natural flax fiber is darker than flax wool.

Jute. This is one of the most popular options among modern owners who build and then insulate the bath with their own hands. It is made from wood of the linden family. Characteristics - a feast for the eyes:

high strength;
resistance to moisture and decay;
good thermal insulation;
environmental friendliness;
ease of use - sold in the form of tapes rolled into rolls.

Among the shortcomings, it is worth noting that jute can stick together under conditions of excessive pressure loads. True, this can be avoided by choosing a heater with maximum density.

Attention! Jute and jute felt are not the same thing at all. The second material has the same disadvantages as any other fiber felt.

The subtleties of the caulking process

The advantages of a caulked bath are obvious: it requires less fuel, and it takes less time to heat up the premises. Therefore, despite the fact that the work is painstaking and time-consuming, it is better not to neglect it.
