Grinding a log house from rounded logs: technology. Two stages of construction of a chopped blockhouse from a gun carriage Further processing of a blockhouse

Hello again!

The time has come to talk about grinding and preparing a dry carriage log house for painting. Labor is painstaking and hard and so more important tool you work for. Weight, ergonomics, minimal vibrations are important - after all, the process takes hours, during this time you can think about a lot, especially about the condition of your hands after a day of grinding with an ordinary grinder.

To achieve the perfect finish, you need to use Festool tools. "Yes, this is the same Makita, only three times more expensive" - ​​you say. This is not entirely true. Festo sanders are balanced, have different soles for different tasks, they have a more powerful dust extraction, more reliable design and better ergonomics. Now I'll tell you about which machine is best suited for grinding a dry gun carriage, and indeed, large areas wood.

This is the surface we had before the grinding process. He specially took a defect that was difficult to remove.

The clear leader is Rotex 150. At the expense of its unique characteristics most quickly grinds off the surface defects of the gun carriage. The sole of the grinder performs eccentric and rotational movements at the same time. When you need to turn on the "rotation and eccentric" mode and quickly grind significant irregularities. It turns out that this is the same "grinder", only very comfortable and less coarse. Then you change the abrasive to a thinner one, turn off the "rotation" mode and finish the surface in the "eccentric" mode. And all this with one machine within a few seconds. Extremely convenient and very effective. In the course of testing, we noted that the Granat series abrasives grind dry pine much more efficiently and hardly clog, unlike Rubin, which, oddly enough, is just for wood and is intended. The Festool staff took note of this moment and took note. And I recommend you if you are going to sand dry coniferous, take only Granat. Due to the larger grain and the greater distance between the granules, it behaves excellently!

Now about the ETS eccentric cars. They are designed to be more fine work... Grinding large areas with serious flaws is sheer torment. It is understandable, you cannot put pressure on them from above - eccentric machines grind only under their own weight, the stroke of the sole is from 3 to 5 millimeters, depending on the model. These characteristics are more suitable for polishing lining or furniture work than for rough sanding a carriage. But it is quite possible to pass ETS with a stroke of 5 mm and abrasive 120 after Rotex. To polish, so to speak, the surface. The ETS EC machine differs from the ETS simply by the absence of a built-in dust extraction turbine. It is convenient for her to work indoors with a vacuum cleaner - she is very lightweight and maneuverable.

We tried to grind the carriage of a huge draw frame- did not work, too heavy and clumsy, and mercilessly dusty. In the end, we decided that Rotex was the right tool for preparing large areas for painting. For hard-to-reach places, Festool has a small Rotex 90, but in our conditions it is more a whim than a necessity. One 150 mm large one can do everything perfectly.

And finally, I upload a video with a bonus: Festool carpentry saw. We end up with a dry gun carriage!

Many thanks to TTS Tooltechnic Systems for providing the tools and room for the review.

Special thanks to the company " Industrial equipment"for organizing the test.

Log house polishing, log house polishing, log house polishing, house wall polishing:

Grinding a log house is performed to give a house from a log or a log house a beautiful decorative look.
Grinding a house from a bar can also be carried out to give better view house from a bar and can be performed, as well as polishing a log house.
Grinding a log house, grinding a house from a bar is done at the beginning finishing works, when does it start fine finishing at home and always before the planning of the caulking of the log house, so as not to damage then the caulked log house of the house with high-speed grinders.
Work on polishing a log house can be done at any time of the year, but it is better to do this when polishing a house from a log is done after standing assembled log house and its complete drying and shrinkage. Grinding a log house after shrinkage or a dry log house is more efficient and economical for the customer, because the consumption of emery materials is much less.
Grinding of a bathhouse and grinding a house from a log is carried out with special grinders - "grinders", with a certain number of revolutions, so as not to burn the wood of the log house from their rapid rotation and not leave it after the grinding work dark spots on wood.
Grinding a house from a bar is carried out after the house has stood and after it has shrunk.
To polish the log house or grind the log house of a bathhouse - only at first glance it seems like a simple and knowledge-free job. Only experienced master with certain skills and knowledge.

High-quality polishing of a log house - what is important to know:

House wall grinding price:

Criterion - polishing of a log house, the price is determined based on the calculation of work for 1m 2 of the wall of the house along a vertical plumb line.
Grinding a log home can be cheaper or more expensive depending on:

• log heights,
• the presence and need to grind the gable of a house from a log or not,
• the diameter of the logs in the frame of the house,
• pretreatment of wood - if the frame of the house was previously treated or painted with glaze paints deep penetration, then polishing a log house is much more difficult, so polishing a house or the cost of polishing a house may be higher,
• the grain size of the grinding material (skin),
• the number of layers of grinding per 1m 2 or the final quality of the polished surface of the log wall required by the customer,
• from the material of the log walls of the house - grinding the walls of the house from a log or grinding the walls of a house from a bar,
• Log grinding cheap (relative to the retail price for grinding a house from a log) obtained when ordering a set of works for finishing the entire house or bathhouse by our team.

Grinding logs at home - surface requirements after work:

The quality of the work performed, such as grinding the walls of a log house, as well as the price of grinding work, largely depends on the materials used.
Grinding of the walls of the log house is performed:

• emery wheel №-36 - rough and medium grinding of the walls of the house from the outside, grinding the log house. Initially, the logs have traces of bark or thick paint,
• emery wheel No.-40 - the usual grinding of the walls of a log house of a bathhouse or a log house during the initial processing of a log house with a scraper or a well-cleaned tree trunk from bark,
• emery wheel No.-60 - ordinary grinding of a house from a bar or grinding the walls of a house from a log. It is used for such work as polishing a log house with a planer and when polishing a house from planed timber or house polishing of their profiled timber,
• emery wheel №-80 - fine grinding for polishing. This polishing of the house is carried out after preliminary polishing of the log house with an abrasive wheel No.-40 or No.-60,
• emery wheel No.-100 or No.-120 - polishing logs, polishing the walls of a house from a log or finishing polishing a bar. The abrasive of the skins is selected for applying a layer of thin varnish after grinding, obtaining an absolutely smooth, mirror surface walls or applying compound

Grinding the walls of the log house is necessary to remove the remnants of bark, knots, stains of blue or mold and other defects from the surface of the log. However, it will be required even if high quality lumber: wood begins to lose its attractive appearance over time. Mechanical processing allows you to return it to its original appearance, you can carry it out yourself or contact a specialist.

Sequencing

This is a rather lengthy and painstaking work: polishing a log house can take several days, it is carried out both manually and using special equipment.

Despite the seeming simplicity, the process requires skill and experience, and also takes a lot of time and effort. In many cases, the owners wooden houses prefer to entrust it to professionals and not waste energy in vain.

If this is your first time working on wood, it is best to start in an area that is inconspicuous. Out of habit, it is not easy to achieve high-quality processing and get a flat, not wavy surface. Do-it-yourself log grinding is carried out in several stages:

Because of this, beginners are recommended to work gradually: first, one wall is cleaned, it is covered with an antiseptic, and then they move on to the next section. If you clean the entire surface, you may not have time to cover it. protective compound, and rework will be inevitable.

Service cost from professionals

Not everyone has the time and desire to process the walls of the house on their own, and in this case it is easier to contact a specialist. The cost of grinding work is quite high, but the costs are justified, since an experienced master will cope much faster and better than the owner of the house himself.

How much does a log wall polish cost? Let's compare examples of prices offered by construction companies in the Moscow region:

Thus, we see that the prices for grinding fluctuate between 200-270 rubles per square meter. meter, the final price depends on total area walls. In addition, polishing required to create a perfectly smooth, even and shiny surface, and impregnation with antiseptics will be additionally paid (the cost of the service is also reflected in the table).

Independent work has one more disadvantage: you have to purchase the entire set of tools and expendable materials, which are spent much faster by a beginner than by a professional. As a result, the benefit turns out to be very small, therefore it is better to immediately contact the specialists.

As a result of professional grinding, no defects will appear, it will allow you to get smooth walls pleasant shade, and treatment with an antiseptic solution will protect them from decay for a long time.

(or you can go to the first photo in the left menu). But, in addition to installing the bath and erecting a roof over it, in 2011 we managed to hold a number of events in the house itself. After completing the arrangement process new apartment, the whole next 2012 we will devote to "bringing to mind" the house and, if possible, the baths. This article will tell you about the features of grinding the walls of a log house (in this case wooden walls at home).

When you communicate with construction companies at the stage of designing and manufacturing a log house, you somehow cannot even imagine all that burden of problems for the further construction of a house or a bath, which will have to be shouldered in the future. And this situation is of course true not only for log houses and baths, but also for any suburban construction.

But when all these problems begin to arise, you begin to appreciate the charm of human relationships, because in one company they will simply turn away from you as soon as you paid the last payment, while in others they will readily help and answer questions even several years after completion. construction of a log house. I am very pleased that the company "Rus Log" belongs to the second category, in fact, that's why I ordered a bath from them this year, and for the same reason I am writing these lines.

Having filled the "bumps" in the construction of the house, and now also the baths, I understand that other developers will also face these problems. Therefore, let our experience and the advice that we received from the specialists of "Rus ..." become available to other clients of this company, and simply to connoisseurs of log houses and baths.

So, our today's story is about polishing the walls of the house. Well, to be more precise, this year we sanded and painted interior walls in the house, as well as internal and external walls in the log house. We will tell you about the grinding of the bath and its coloring in separate articles (see links), there we will briefly dwell on the features relating specifically to the work on the bath. We will also talk about painting the walls of the house in a separate article, this issue was also not as simple as we had assumed before.

Photo of the living room in 2011 after sanding the walls.

How our walls look after sanding can be seen in the previous photo. Of course, the house began to be perceived in a completely different way. My only main mistake is that I had to do the grinding before installing the floors and ceilings, but we will dwell on this in more detail a little later. And now let's go together all that difficult path that led to such beauty.

Note from Fall 2013. It is always interesting to look a little ahead in order to understand, in fact, "for the sake of what all this was started". In the next photo, you can see how the living room began to look after sanding and painting the walls. Well, and at the same time after a number of other events (from a fireplace and warm floors, to tiles and doors).

Photo of the same living room, but taken in the fall of 2013.

Initiative is punishable or "come on guys"

At first glance, you cannot say that grinding the walls of a log house is a hard work that requires skill, strength and endurance. When two years ago I found out roughly how much it would cost me to grind at home from the inside, then I said: what kind of nonsense, I myself can do just fine. Just think - drive and drive with a grinder. I was also "motivated" by my good friend and senior friend, let's call him Yu.V., since I did not ask for his consent to this publication. He at one time (as a teacher, having two higher education, degree of candidate of science and associate professor) in a couple of weeks built country house for his father-in-law. In short, in addition to a refined mind and a rather sharp tongue, which many were afraid of, he also had golden hands.

Of course, at work we often discussed the construction of mine and his summer cottage. And once he asked me what I actually did in the country with my own hands, because you need to put my heart and soul into the house. So, I say, my wife and I seem to have developed the project in agony, I myself planned the electrician and put it together, perhaps that's all. And he told me - well, really you yourself can not sand the walls, and really, I thought, why not. By the way, Yu.V. he was very unlucky with the builders, he also built a log house, but he ordered it through mutual acquaintances, and they let him down.

Heavy male work- polishing the walls of the log house

No sooner said than done. I already knew at that time that they were polishing log walls an angle grinder, in the common people - grinder... Entering a large hardware store, I asked to show me all the attachments for the grinder. Having chosen two, in my opinion, the most suitable, I asked to choose the disks for them. I already knew that wheels with a grain size of 80 are used for grinding. I especially liked the German attachment with Velcro, it was, of course, expensive (about 1000 rubles), but, in my opinion, very convenient.

Arriving at the dacha, I dropped everything and rushed to try my acquisitions in business. I had the prudence to start from the "invisible" place. In the bathroom on the first floor, I chose the wall where the shower stall will stand. The very first attempt at grinding showed that it is far from so simple.... The grinder was simply pulled out of my hands and thrown from side to side, sparks began to fly in all directions from under the circle on the new skin, because of this, scuffs arose, I could not make a smooth strip, everything turned out in some kind of waves.

But the most unpleasant surprise awaited me when I tried to grind the log at the horizontal joint between the crowns. My vaunted German nozzle with its upper (i.e. back to the skin) part left a fat black line on a nearby log... Another thing that unpleasantly struck me was that 80s discs were wearing out at a very incredible speed. The package of discs brought in melted before our eyes. I tried the second nozzle, there grinding disc secured with a bolt. As it turned out later, this was already closer to the truth, but even here it was very difficult to grind the logs in the intersections and at the joints. I replaced the German Velcro attachment again, but in frustration forgot to attach the sanding disc itself. When I began to run the grinder along the log, I immediately felt that something was wrong. And then it dawned on me that "it was not the reel ..." and I myself ruined the attachment for almost a thousand rubles. This was the last "dot over i" and I finally understood that everyone should mind their own business.

Later, observing the work of the guys and communicating with them, I realized some of my mistakes. First, you need a different (second) nozzle. Secondly, the new disc must first grind off a little on the auxiliary section of the log (usually in openings for interior doors, then what will be closed in the future with casing boxes) - while the largest grains fly off and the disk will not "cut" the log and spark. Thirdly, I realized that the grinder should be moved not with the movement of the hands, but with the shoulders and forearms, then smoothness and parallelism of the movement will be achieved, respectively, the log will be smooth and without "waves". The last recommendation will be clear to volleyball and tennis players. In volleyball, when receiving the ball with two hands from below, you also need to "work" with your shoulders and torso, and not bend your elbows, otherwise the ball will fly in an unpredictable direction. Likewise in tennis, receiving the ball with a racket held with both hands also requires similar work of the whole body, not just the hands.

We got a little distracted. In short, even if I knew all this in theory, it would still turn out to be hard work... But it was also necessary to scrape off the top layer of wood in the corners with a chisel. In short, then I clearly decided for myself that you need to do something around the house or the bath, but you need to do what you are good at.

By the way, to be objective, I was not the only one who had such a "crazy" thought. WITH light hand I got acquainted with the staff of "Rus" and maintain friendly relations with Maxim Marinin, our famous figure skater and just a wonderful person (editor's note, more details about the bath, built by Maxim Marinin, told).

Since we are in approximately the same state with him, in the sense of being dragged out into the construction process, we periodically exchange interesting and useful information on various aspects of construction. So, once Maxim wrote that he had purchased a good grinder (not a grinder, but a specialized grinder) and was planning to grind the bathhouse frame on his own. He, like me, was alarmed by the cost of this work - at first glance, it seems overstated. I told him my story described above and recommended that he leave it at the mercy of specialists, and do something more familiar myself. But Maxim, as determined as I am, and he decided to try everything on his own experience. The result turned out to be the same, we both realized that "Caesar is Caesar", and it is better to earn money in the way we are used to - it will be more effective.

Grinding tools and consumables

Before bringing the builders to the dacha, I attended to the purchase of grinding discs. The question turned out to be rather nontrivial. But first, a few words about the process itself. The main plane of the chopped walls is cleaned with a grinder with a nozzle put on, on which a grinding disc is fixed with a bolt. But there are places where the grinder does not reach - these are the corners of the cuts, walls near the ceiling or near the floor (if you, like me, already have a floor mounted). There you have to work by hand - with a chisel. The photo below shows two such cut angles. The upper corner has already been cleaned with a chisel, but the lower one has not, the circles are clearly visible, where the disc could reach.

Work with a chisel in the corners of the cut. In the upper corner, the tree layer was manually removed, in the lower - not yet.

It is clear that grinders, attachments and chisels are the concern of builders, but I advise you to take care of the grinding discs separately, so that unpleasant incidents do not happen.

Grinding discs left in "packs". The photo on the left shows the mark about the grain size of the disk (60) in blue.

The best option, if the builders will take on the "procurement" of sanding discs, it is more difficult if you have to do it (for example, buy in addition). The fact is that these disks are required very well. a large number of... Offhand for home and for the bath, we took about two and a half boxes. Each box contains 8 packages, each package contains 25 discs. In total, there are 200 discs in the box, about 500-600 discs were used in total. As the builders told me, on square meter the walls go from 1 to 3 discs, so count. By the way, counting the area, and hence the amount of work, and therefore your costs, must be correct. Craftsmen use the so-called height factor. The fact is that your walls are uneven, but with rounded crowns. Therefore, several control measurements are made, a tape measure is taken, and all the bends of the crowns are wrapped around the tape. It turns out that with a ceiling height of, say, 2.5 meters, the real height of the wall is about 3 meters. This was news to me, but now it is no longer for you.

Let's go back to the disks. If you go to a construction hypermarket and try to buy so many discs there, you will understand that it is cheaper for you to cover the walls with gold leaf. Of course, I had to promptly buy several dozen disks, especially those with an increased diameter (150 mm), to be honest, this is not a cheap business.

So what do you do? There is a way out: turn to " domestic manufacturer"! The fact is that in supermarkets mainly imported products are presented, and the specialists of Rusi Brevennoy recommended purchasing discs from the Luga Abrasive Plant - they are several times cheaper, and in terms of quality they are not much inferior to imports. It is clear that not everyone will be able to “hit the road” to Luga, look for this plant, and so on. Here it will be optimal if the builders organize it. I am grateful to the leadership of "Rus ..." that I had no problems with this. Moreover, usually large construction companies How "Rus Log" buy these discs in bulk (by wholesale means - several dozen boxes, that is, thousands of discs), which costs them significantly less than if you came to the factory yourself. Unfortunately, or rather to my sincere amazement, the Luga plant has neither a representative office, nor even point of sale in St. Petersburg, which is a pity.

And one more aspect concerning disks is their grain. For for final grinding, use discs with grit 80 or 60(see the circled numbers in the photo above). Of course, the result of using sandpaper 80 is more pleasant to the touch, but most likely it will have to be sanded in the second layer, and for the first time, go with a coarser sandpaper. In the house we made the 80th, and in the bathhouse the 60th, but in one layer. In principle, it feels almost imperceptible, especially after painting. By the way, looking ahead, I will say that after the first layer of water-based varnish you will have to sand the walls again, this time simply by hand, without a grinder, because it is the water-based varnish that lifts all the pile formed on the surface. But we will talk about this in more detail in a separate article.

In addition to 60 and 80, builders use grinding discs, grit 40- for grinding the ends of the logs, of course, this skin will take much less. I repeat - what's in ideal option All these problems should be taken over by the builders, so that you do not have to rush around St. Petersburg and the Leningrad Region in search of certain grinding discs, leaving work and business.

Resurfacing at home: the first and unsuccessful attempt or the role of recommendations

So, by the middle of the summer, I had a paradoxical situation, that there seemed to be money for construction, and there were builders for individual work, but I could not start work. The fact is that at that time I was kept by grinding the walls in the house. I could not install casings and internal trims on windows (the specifics of our windows are described) without sanding the walls. For the same reason, I could not lay plumbing communications around the house, respectively, make warm floors, etc. But the most important thing is the fireplace. The fireplace is "a separate song". It was designed for us according to the author's project based on the Swedish Keddy fireplace cassette. We decided to make the cladding of the fireplace from talcochloride, it was ordered back in winter and was finally ready by the summer. The installation of the fireplace, as you understand, was also held by grinding. And the fireplace itself kept the insulation of the roof of the house (by the way, we did not have time to make the roof this year and moved it to 2012).

I called Denis Migachev, gene. director of "Rus" and asked if his "fighters" would be able to polish my house, and at the same time the bathhouse. He replied that, unfortunately, all the brigades are busy and on the road, that at best the nearest brigade will be free in 3-4 weeks. I didn't want to wait so much, the summer is passing. We clicked a cry among our acquaintances and one distant friend of a friend said that he had people in mind who had experience sanding the walls of wooden houses. At that time, I still did not know all the intricacies of grinding and considered that with this laborious, but in principle a simple matter, this brigade can handle it too.

On the next Friday I went and took two "specialists" from the previous object and brought them to my dacha. The guys turned out to be from Ukraine, I organized their entire life, we walked around the house and examined all the walls. Andrey, he was their eldest, said that for grinding the logs adjacent to the floor and ceiling, he would need discs of a larger diameter (150 mm), which I should have bought.

Half Saturday I was running around the shops in search of these discs - all to no avail, Velcro - please, but there were simply no such clamping discs. Desperate, I again called my "magic wand" Denis Migachev. He immediately said - you need to go to the "Castorama" store, and indeed, there I took all available discs of the size I needed "to zero", by the way, the price tag "bite", each disc cost 50-70 rubles. Denis also chided me that I did not wait for his guys, because here he definitely guaranteed quality. I had to apologize and refer to an unacceptable, as it seemed to me then, a time delay.

Arriving home, I called my grinders, "reported" that their request was fulfilled - the discs were purchased. And this Andrey answered me and said that in fact they had already left the dacha, they were not interested in work and the conditions did not suit them. I was just taken aback by what I heard and slowly sat down on a chair. Wait, I say, I am inclined to dialogue, if there are problems - voice it, if this is really so, I am ready to raise the price of the work. He replied to me that the house is old (although the log house is only 3 years old), it is very hard to skin, you first have to go through it with a coarse-grained skin, and then again - 80. I hung up and began to come to my senses. In my 45 years, no one has done this to me. Well, find the courage in yourself and tell the customer that you are not interested in this, but tell him to his face, and like that, leaving someone else's trusted house, and running away like a rat from a sinking ship, I could not understand. Having come to my senses, I called this Andrey again and already calmly "put him in his place", explaining that "grown-up boys" do not do this, and that if I find at least the slightest problem at my dacha, then I will find him with a friend throughout the Leningrad region. In fact, I was not cunning, if it became a matter of principle, then thanks to the connections of my wife, we would be able to “ruin the life” of these guys, just usually I don’t want to waste time and get our hands dirty on such people. My principle is to draw conclusions, forget and move on. This is what we did. The next day we arrived at the dacha, found the keys to the gate and from the house in the place indicated by the would-be builders, checked that everything was in order and in place. They began to think about what to do next - time is passing.

The second attempt - with a guaranteed result

As you understand, my next call was again to Denis, I told him the story and asked him to reserve his builders for me, we had nowhere to go, so we were ready to wait. Denis promised to speed up the process, and indeed, three days later they removed a specialist named Adrian from the facility, called his cousin Ivan, a beginner specialist, to help him, but Adrian promised to organize the learning process "along the way" and guaranteed that everything would be on the highest level... It was supposed that in a week or two a couple more guys would arrive, but later we refused this, since the pace of work of the builders, and most importantly, the quality, satisfied me.

The main task that I set for the grinders was to quickly sand and paint the house, primarily those rooms where the fireplace will be located and the chimney will pass (on the second floor). Secondly, I decided to polish the inside and the bath in order to “close the topic”. Looking ahead, I will note that later we made a decision to polish the bathhouse outside, “walk, walk like that,” although, of course, additional justifications appeared for this step.

The work has begun. The guys started from the second floor so that the dust would not settle on the work already done. I’ll say right away - of course, there was “unmeasured” dust. It is convenient to use ordinary brooms and a vacuum cleaner to clean the walls from dust. Of course, it is difficult without a vacuum cleaner, especially later - when you need to clean the corners and joints of the logs before painting. I still had a "technical" vacuum cleaner, which we bought during the renovation of the apartment, here it once again served.

Grinding is a mountain of garbage ... ... or fertilizer, depending on how you look :)

Based on the results of the work of the first "Uh brigade", I realized that it was necessary to protect the mechanisms plastic windows and a roof membrane. Therefore, I bought several packs of film (it is thin, and there is a thicker - the second is better) - it is usually used to cover furniture and floors during repairs. First of all, I asked the guys to close all window openings with foil and to knock out the entire roof on the second floor with a stapler (now from roofing cake we only have tiles and a waterproof membrane in the house), we planned to do the rest of the inner roof after installing the fireplace, sanding and painting the walls.

And so the work began to boil. I will say right away - it was a long process, in total the guys worked for me for almost a month and a half. But during this time, the house was sanded from the inside, the bathhouse was sanded on both sides, all this was painted three times with varnish, and inside the premises - after the first layer of varnish, the pile that appeared was also manually sanded with sandpaper.

Observing their work, I studied grinding technology for the sake of interest. Let's focus on the most important points this process. Grinding of walls from a gun carriage can be divided into three components: processing the upper and lower edges of the log, as well as processing the flat part of the log. For round logs, everything is somewhat more complicated, there you have to smoothly bend around all the roundness of the wood. The steps described are illustrated in the following three photos.

Processing the bottom edge of a log

Grinding the upper edge of the gun carriage

Wall plane processing

Particular problems were caused by the sections of the walls near the ceiling and near the floor. Therefore, I will once again remind you of my recommendation: the frame should be sanded BEFORE installing windows, installing ceilings and floors. The main thing is that the log house is under the roof. Here the presence of lags is welcome, it is convenient to temporarily throw boards on them - this is what happened with me in the bath.

By the way, let's talk about one more recommendation that came to light in the course of work. Of course, it is better to grind a new log house than an already settled one. In addition to the mentioned windows and floors, the process of hardening of wood also comes into effect here. Accordingly, the consumption of skin on such a log house will be slightly higher. True, belated polishing also showed advantages, we will talk about this in more detail in a future section devoted to the insulation of a log house after shrinkage.

Let's go back to the difficult areas to work with. With the floors it was a little easier. We plan to organize underfloor heating on both floors, heated by a heat pump, so the floor level will still be raised by 5-8 cm. This allowed us not to "fight" for the lower edges of the walls. But with the walls at the ceiling of the first floor really had to suffer. While we are planning to do on the first floor stretch ceiling(they hide well the unevenness of the logs of the walls), they will be away from the existing rough ceiling from OSB by only 2-3 cm, so sanding the upper parts of the walls was essential. Several times my workers threw up their hands and said that they would not be able to sand this or that part of the wall. We understood that, of course, this can be done with a chisel, but this is absolutely hard labor.

In life, I am an optimist and an engineer, so every time I calmed Adrian and every time we found a solution. These solutions were born "in pain", therefore, given that they may be useful to you, we will give them briefly.

Grinding hard-to-reach places under the ceiling, in some places I had to modify the tool, be smart, or just work with a chisel

"Know-how", which appeared as a result of brainstorming:

• the guys cut off the rubber pad holding the sanding disc and the sanding disc itself. Thus, from a disc with a diameter of 125 mm, we obtained a disc with a diameter of 70-80 mm, which made it possible to work in many hard-to-reach places;
• somewhere I closed my eyes to the “waves” on the surface of the crowns, because I understood that this area can be sanded only with short vertical movements;
• without hesitation, I allowed the guys to "scratch" the rough ceiling, because otherwise it would not work;
• where it was very tight, I had to work only with a chisel, but there were only two such places left, and even then small ones.

By the way, my experiments with the grinder came in handy. In one of these cases, the emotional Adrian said in his hearts that he couldn't get in there. And I look and think, why do you need to make movements from top to bottom, and if you turn the grinder and start working from the bottom up. Adrian says to me that it’s impossible, the Bulgarian will simply fly out of my hands. Let's try - I said. Believe it or not, in front of the "amazed public" I managed to neatly clean up a previously inaccessible area. Damn, "skill is not spent on drink", I even thought.

Of course, one cannot fail to mention another rather laborious stage of work - cleaning the surface of the logs in the corners of the cut with chisels. The photo below shows this operation in close-up from various angles. In the photo - Adrian himself. His brother, Ivan, out of natural modesty tried to avoid the lens, but I didn't insist.

Time-consuming work of manually scrubbing the corners of overcuts where the grinding disc is missing.

On the right side of the photo above, you can clearly see that the crowns were not completely polished - the guys then processed the curtains for window and door openings separately. This was due to the fact that most of the windows were covered with a film at that time.

The next photo shows a close-up of a wall made of round log... Traces of discs are clearly visible. This is what the wall looked like after passing with a coarse sandpaper with a grain of 40.

Polished wall - close-up. Traces of discs are visible. This wall was sanded twice, first with 40 and then 80. The photo shows the result of rough grinding.

As a result of the work done on polishing the house, the living room simply "played". Frankly, my wife and I do not regret the money spent on grinding, because it essentially replaces the traditionally expensive final wall decoration. Once one of our friends, having visited our house, asked, and what will you sheathe the walls with? My wife and I looked at him like "Lenin at the bourgeoisie" and said, what are you, for the sake of these wooden walls, everything, in fact, was started!

As a result of the resurfacing, the house looks "like new"

At the end of this article, albeit running a little ahead, we will show how the same room began to look, but already with painted walls and an installed fireplace... The upper decorative grate is still missing on the fireplace, so the duct pipes are visible.

Do not be surprised that the fireplace podium is raised above the floor - this is by design, since the subfloor is CBPB boards insulation will be laid, and then in the underfloor heating pipe screed. According to our plans, the level tile just should go to the level of the fireplace podium.

To take a closer look at the walls, we will give a photo of the chimney against the background of the wall of the attic floor. In general, we were satisfied with the quality of grinding and painting.

As a rule, walls and floors are sanded in 2 - 3 passes. For the first pass, the plane is leveled, protruding edges, ends of the logs are removed. The second pass with finer grain gives the surface smoothness and prepares it for painting.

Grinding allows the wood to return to its natural beautiful structural view... To preserve it for many years, polished walls or floors must be protected from UV and moisture. To do this, paint it or soak it with oil, cover it with parquet varnish.
