Practice how to lay the floor from a parquet board -

We often write about the projects of our architects anddesigners. But readers are wondering how they live? What interiors and what materials do they choose for themselves? One of our permanent experts, the architect Ruslan Kirnichansky, shared his experience of replacing the floors in the apartment with Ruslan Kirnichansky, an architect, a designer, an expert and a design critic. He is engaged in a variety of activities, including building construction and working with the internal space. It conducts projects both in Russia and in Western Europe. - How to replace floors correctly? If you type this query on the Internet, you can find many articles with a variety of tips. Since I myself dealt with this process, I can show the whole algorithm of actions, as well as talk about those pitfalls that can arise in the process of work.

A bit of history

In our country, floors are often made of wood. In each model house, the floors have one "pie" - these are wooden logs, covered with a floorboard, on top of which lay parquet (in "stalines"), or covered with particleboard or linoleum. I think that each of us remembers how these floors creak and sag. But this is not all the disadvantages of wooden floors. The tree is a good building material, but short-lived. The fact is that the log frame, whether it's a board or a beam, continues to "live" - ​​reacts to a change in external conditions: swells at high humidity, deforms under physical influence. All this leads to rapid wear of the material. The service life of the wooden "pie" of the floors is not more than 20 years, provided that the operation is carefully maintained. This is a photo of wooden floors that have served 30 years. And these pictures were sent to me by the builders during the dismantling. Look at what was hidden by the remnants of the parquet of the sample of the 80s. Previously, this apartment was inhabited by a family consisting ofof four people. When I first examined the room, I immediately presented the scale of the forthcoming works. Moreover, my steps were accompanied by a pitiful creaking of the sexes. They were in a deplorable state: the logs were rotten, in places there was not enough parquet, which peeled off. The floors were uneven and pressed.

Creating a new "pie" of the floors

You can not leave such a floor. I was a little pity to lose the remnants of the old parquet, but for the restoration of the floors were not good - they needed radical changes. During the dismantling, not only debris and dust layers were found under the floors, but also other artifacts: the remains of small rodents who, most likely, quietly and imperceptibly lived in voids under the floorboard. After the dismantling work began to collect a new "cake" of the sexes. The first thing that has been done is the treatment of the floor slab with a hydrophobic composition: a special water-repellent mastic was applied to the entire floor surface. This is important to ensure the protection of the wiring that passes in the slab. The second step: applying a layer of sand 1 cm thick. This is necessary to provide noise insulation. The slab in my house has a thickness of 200 mm, which at first glance seems sufficient. But since the slab of the ceiling is hollow, which does not prevent the spread of sounds, I decided to soundproof the floors. Then there were exposed beacons - markers of heights,laid layer of penokleksa - soundproof material, which is also a heater. One of the important factors of comfortable living is the possibility of seclusion and silence. Extraneous sounds from the neighboring apartment annoy everyone. I do not want to hear who and how to live from below, so I paid maximum attention to soundproofing. Once I arrived in the apartment before the repair work began. The former tenants left the piano in the apartment. Imagine my surprise when a doorbell rang: a pretty woman stood on the threshold, who praised my ability to play the instrument and asked me not to jump around the apartment again. It turned out that my movement through the rooms was heard in the apartment below as a parade of elephants, and "Moonlight Sonata" with errors on the upset piano - beautiful music. After laying the penopolix, a screedfrom the M-300. Lighthouses helped to maintain the level and fix the slabs of the slab overlap. Important: a layer of concrete screed should dry well. During the summer period in the central part of Russia, the natural drying time of the screed takes at least 28 days. If the screed is not dry, then the moisture that has remained in the layer can deform the finish coating of the floors and shorten the life of such a structure. In 10-15 years, the poorly dried concrete screed will turn into dust. The service life of concrete screed, manufactured according to the construction regulations, is at least 50 years. My advice: if there is no time to wait for natural drying of screeds or repair work is carried out during the cold season, use special construction guns - this will shorten the drying time. After two weeks of drying the screed usingbuilding gun guns, one layer of liquid floor was applied. The liquid self-leveling liquid floor concealed the small unevenness of the screed. Drying the floor is necessary for five days, I do not recommend using catalysts to reduce the drying time, because chemical additives and thermal effects have a negative effect on the strength characteristics.

Laying of floor material

For the finish floor I chose a parquet board,which consists of three layers of different types of wood (the upper layer is oak). I will not say that a parquet board cost a lot of money - the costs are comparable to the average price of a laminate, which does not stand any comparison either in quality or in technical characteristics. I always recommend using natural materials that are environmentally friendly and not a synthetic pool. Laminate, as it would not try to praise the producers, is a surrogate sawmill. Otherwise, would the manufacturers do imitation wood on the laminate? The big difficulty was to find a quality parquet board. But proven suppliers did not disappoint me, offering options for good parquet and at an affordable price. The parquet board was laid on a special substrate, which is an insulator of screed and wood. In addition, the substrate allows you to avoid creaking. Thus it was possible to create a durable andquality floor, which has not only aesthetic properties (parquet), but also does not allow the spread of sounds and noise, which is especially welcome in the apartment below: now they will never hear how "bad" I play the piano. All the work was carried out by a construction team consisting of specialists who have proven themselves in working on my projects. By the way, I also won on height: the level of the "pie" of the old floors was 12 cm, and the new floor occupies only 8 cm. This is +4 cm to the height of the ceilings, which is also good!
