How to attach the floor board to the joists, nails or screws. How to attach floorboards. Methods for fixing the flooring What size screws for the floor

When building your own home, it is not enough to pay attention to what materials are used for this - you also need to be very careful about the method of attaching these materials. As you know, any building material “requires” its own fasteners and method of its application. The floorboard is no exception in this regard. Considering the loads that fall on it, choosing a method for attaching a floorboard simply cannot be an insignificant issue. Indeed, if the boards are not fastened well enough, after a short time they will begin to “demonstrate their dissatisfaction”, loosening and changing their position, and the initially smooth and even plank floor will not only begin to creak underfoot - it will literally fall apart into individual components.

What fasteners are used to secure the floorboard?

Today, manufacturers produce special screws for floorboards, which ensure reliable fastening of the board to the base and guarantee a long service life of the flooring without any additional investments in its repair.

However, it is worth noting that such self-tapping screws are somewhat more expensive than conventional fasteners used in construction. But at the same time, they perform their work very efficiently and as efficiently as possible. As a result, the entire floor covering will last much longer than if conventional screws were used to attach the boards. Saving on self-tapping screws in this case is an almost guaranteed need to repair the floor in the very near future. And on the boards themselves, fasteners that are not specifically designed for them can have a very negative impact - for example, screwing such fasteners into the board can cause a crack.

Features of self-tapping screws for floorboards.

As a rule, screws for floorboards are produced in several standard sizes: 3.5x35, 3.5x40, 3.5x45 and 3.5x50 mm. The size of the screw is selected depending on the thickness of the boards used when installing the flooring. All self-tapping screws have a special protective coating that prevents the possibility of corrosion on their surface.

And you can find out the special screws for attaching the floorboard very easily - there is a milling cutter at their tip, which allows you to screw these screws into the board without first drilling the holes. This allows for a more “tight” fit of the self-tapping screw itself, and therefore a more secure fixation of the board to the base. In the same case, if you pre-drill a hole for a self-tapping screw on the base of the floor, spontaneous unscrewing of the self-tapping screw may occur, and it is not always possible to select the correct diameter of the drill for the subsequent “fitting” of the board onto the self-tapping screw.

It is worth saying a few more words about the geometry of the milling cut on the screw - the cutting angle is selected in such a way that the screw easily fits into the wood without splitting the board. And the entire form of the self-tapping screw is subordinated to this task.

Another feature of the self-tapping screw for fastening a wooden board is the absence of threads on its upper part - this allows the self-tapping screw to more tightly attach the floorboard to the base.

1. The distance between individual screws when attaching a wooden board to the base should be from 25 to 30 cm.
2. Some craftsmen recommend using a special glue when laying floor boards on a horizontal base, which is used when laying parquet. This is a completely possible option if there is no additional waterproofing layer between the boards and the base - for example, a moisture-proof film. But at the same time, it is important to know that special glue can only be an additional way to fasten the board - the main method is still self-tapping screws. Without them, it is simply impossible to achieve a sufficiently reliable fastening.
3. When ideally connecting flooring boards to each other, we must not forget that the flooring should not fit closely to the walls of the house along its entire perimeter - about 7-10 cm of free space should be left between the edge of the covering and the wall.
4. It is possible to completely “hide” the screws used when installing a wooden floor. To do this, you need to “recess” the head of the screw into the board a few millimeters, and “mask” the resulting hole using a piece of wood of a suitable size and shape, the species of which must match the species from which the boards are made. Some manufacturers of luxury building materials produce similar “stoppers” that are included with the boards themselves.

When arranging flooring in your home, you need to pay close attention not only to the type of materials used for this. It is necessary to carefully select the method of fastening the cladding.

Everyone knows that each building material needs its own type of fixation and method of its use. In this case, the plank covering is no exception.

Considering all the loads that fall on floor cladding, the choice of method of fastening the boards is very, very important. When individual floorboards are not secured firmly enough, after a certain period of time (often very short), they begin to loosen. They change their original position, the initially flat and smooth floor begins to creak underfoot, and often simply collapses.

This article is about how to fix a floorboard correctly and efficiently. The most reliable and common methods will be considered.

Existing fixation methods

Floorboards are fixed in three main ways:

1. so-called secret - using nails or self-tapping screws;
2. adhesive analogue;
3. and using clamps.

Fastening boards with nails

1. In this way, the boards are usually attached to a wooden (solid or assembled from logs) base.
2. The initial row of floorboards is laid using nails driven into the base through the tongue and groove at an angle of 45 degrees. Then they are driven into place.
3. To avoid damaging the tongues, holes for fasteners must be pre-drilled with a drill.
4. In the process of adjusting the next row of planks, the nails must be hidden.
5. All other rows of planks are fixed with your own hands using nails, in the usual way - through their surface.

Note! When it is necessary to replace several floorboards when repairing the covering, make sure that each of them ends under the center of the crossbar. Otherwise the coating will not be durable.

Adhesive installation method

When board cladding is installed on a solid base, adhesive can be used to secure it.

1. For this purpose, the grooves of a row of boards are lubricated with an adhesive compound (for example, ordinary PVA) before they are placed on the tongues of the adjacent row.
2. The instructions instruct to apply glue in a thin layer of 1/2 mm, every 0.5 m, along the entire surface of the groove.
3. The final tongue-and-groove edges are also coated with the composition.

Fixation with clamps

Some manufacturers provide boards with clamps that are inserted into the slot on the inside. These elements are needed to fasten the planks together.

A little about how to properly attach the flooring in a boring way.

1. After installing the subfloors, lay a layer of waterproofing on them. Secure the material to the walls with self-adhesive tape.
2. Hammer the clamps in the direction of the tongue into the cracks of the first row of boards to be laid.
3. Lubricate the planks with glue along their end seams. Place the first row.
4. Place wedges approximately 1 cm thick between the wall and the boards.
5. Next, secure the clips to the second row of planks. By carefully tapping with a hammer (through a piece of protective block) on the edges of this row, fix the floorboards.
6. The entire coating is installed in a similar manner.
7. Next, remove the wall wedges and install the baseboards.

Special self-tapping screws for floorboards

1. Such fasteners are produced in several standard sizes: 3.5×35, 3.5×40, 3.5×45 and 3.5×50 millimeters. The size of the screws is selected based on the thickness of the floorboards used.
2. Such self-tapping screws have a protective coating that prevents the appearance of corrosion on them.
3. There is a cutter at the tip of the mount. It makes it possible to screw screws into wood without drilling preparatory holes.

Note! This design ensures a tighter screw fit. Consequently, the fixation of the boards to the subfloor is more durable.

1. The geometry of the milling cut is special. Its angle is chosen in such a way that the screw enters the wood easily, without splitting the planks.
2. Another characteristic feature of self-tapping screws for floorboards is that there is no threaded thread on their upper part. This circumstance contributes to a tighter fit of the floor covering to the base.

1. The pitch between individual screws when fixing the planks to the base should be from 25 to 30 centimeters.

used when laying plank floors. For this purpose, it is necessary to recess the heads of the screws into the wood by 3/4 of a millimeter. The hole formed as a result of these actions can be closed using a piece of wood that matches it in shape and size. Its type should be the same as that of the flooring boards.

A self-tapping screw is a fastening element that consists of a rod with an external thread and a head. When the product is screwed into the required part, an internal thread is formed, which allows for the most durable connection of the workpieces. When choosing a suitable self-tapping screw for wood, it is necessary to take into account not only the specific type of product, but also its length.

Classification of mesite wood by color

Manufacturers produce many varieties of fasteners used for working with wooden workpieces. The main characteristic feature of such products is the wide thread. However, there are self-tapping screws with fine threads, and most often they are used for working with hardwood.

Depending on the color, hardware is:

• Black, used primarily for rough work. This is mainly due to the fact that these products have a rather low resistance to corrosion processes, and with high environmental humidity, rust forms on them quite quickly;
• Yellow and white. Products in this group are coated with brass or zinc, which increases the service life of the fasteners. Both options are quite expensive.

Rules for choosing the length of the self-tapping screw

When choosing hardware for working with wooden parts, you must follow a simple rule. The self-tapping screw must enter the main workpiece to a depth of 1/3 of the thickness of the attached part. If two wooden blanks are additionally secured with corner elements, in this case the hardware should go to a depth of up to 1/4 of the part being attached.

Based on this, certain conclusions can be drawn:

• Self-tapping screws up to 35 mm long are ideal for fastening plasterboard structures to a wooden base, and in addition, they are perfect for working with wooden frame cladding and OSB;
• The hardware, the length of which is 51 mm, is ideal for working on two-layer cladding of a wooden frame with plasterboard slabs. It is recommended to carry out such an operation in places where there is increased traffic;
• If you use hardware with a length of 75 mm or more, you must first drill a small hole in the wooden base. Otherwise, microcracks may occur and the fibers will be damaged;
• If there is a need to use self-tapping screws with a length of 100 mm or more, then additional difficulties may arise. And therefore, to avoid them, it is enough to drop a little machine oil into the pre-drilled hole.

Self-tapping screws

When installing flooring in their home, owners carefully select the highest quality materials, but the reliability and durability of the flooring depends not only on them. Even the most expensive tongue and groove board can quickly fail if it is not properly attached to the base.

Today, craftsmen have access to several methods of laying and fixing the finished floor, therefore, before attaching floorboards, it is necessary to consider all the options and choose the optimal one.

On what basis can the flooring be laid?

Can be installed on various types of surfaces. The basis may be:

• concrete floors with a leveling layer;
• logs located on top of floors or laid on brick supports;
• false base made of moisture-resistant plywood;
• old floor;
• rough base made of low-grade lumber.

Before attaching the floorboards, you should remove them from their packaging and lay them out in the room in which they will be installed for 3-5 days. This is necessary so that the wood gets used to the surrounding climate and does not deform after fixation. It is also very important that the humidity level of the substrate being finished does not exceed 12%, and the level inside the room is within 50%.

Methods for fixing the board

The boards are fastened in one of three possible ways. Namely:

• using glue;
• special clamps (clasps);
• nails or screws.

Fastening with nails

First, let's look at how to fasten floorboards with nails. It should be noted right away that this method can only be used if the flooring is fixed to a solid wooden base or along joists.

So, the installation technology includes the following steps:

1. Logs are installed from square timber at a distance of 70 cm, pre-treated with an antiseptic compound. The thickness of the boards should be between 50-70 centimeters.
2. Sound and heat insulation is installed. For these purposes, mineral wool or expanded clay can be used.
3. They begin to install boards on top of the insulating materials, placing them with the grooved side towards you.
4. The first plank is fastened with nails so that their heads do not interfere with the further installation of the plinth.
5. All subsequent boards are fixed with nails, which are carefully driven into the groove at an angle of 45 degrees. In cases where the plank is shorter than the length of the room, the joining of the two elements is located on the log.
6. After laying the finished floor, you can begin sanding and decorative processing.

In the same way, you can fasten the floorboard with self-tapping screws. For this purpose, special fasteners designed for working with wood are selected.

Wood screws

If you decide to do the installation yourself, you will probably be faced with the question: what screws to use to secure the floorboard?

Professional craftsmen have long been using special screws when laying plank floors, as they provide the strongest possible fixation of the planks and help increase the service life of the wood material. The main difference between such products is their shape and the presence of a protective layer.

For a long time, it protects the metal element from the formation of rust, which can lead to weakening of the fasteners. They come in different sizes, the choice of which depends on the thickness of the floorboard.

The tip of the screw is made in the shape of a spatula, thanks to which the product is easily screwed into the board, weaving wood fibers around its thread. At the base of the cap, the metal is completely smooth, which allows you to attach the flooring to the base as tightly as possible. Thus, the self-tapping screw is securely fixed in the structure of the facing material and ensures the immobility of the boards until they require replacement.

Features of laying floors using glue

This installation method is widely used in rooms with low ceilings and can only be carried out on a solid and smooth base. The process is very similar to laying parquet, but differs in that the planks are additionally fixed with self-tapping screws. To understand how to properly attach a floorboard with glue, you should consider this technology in more detail.

1. First of all, the base is covered with waterproofing material, on top of which moisture-resistant plywood with a thickness of at least 18 mm is laid. It is screwed to using screws or dowels. Before attaching the floorboards, the prepared surface is thoroughly cleaned of dirt and dust.
2. Using a notched trowel, glue is applied to the base, where all the flooring elements are carefully joined.
3. Additionally, screws can be screwed into the grooves of the boards to ensure their immobility.
4. In some cases, for a stronger connection, the grooves are also coated with glue, after which they are placed on the tongues of the previous row.

Fastening with clamps

Manufacturers of tongue-and-groove boards often equip their products with special clamps. They help secure the material in a secret way so that all fasteners remain invisible. So, let's look at the technology for installing wooden flooring using clamps.

1. Special strips are installed on the internal projections of the grooves, which are fixed with self-tapping screws. It should be noted that the head of the bolt should not prevent the tenon from fitting tightly into the groove.
2. Using nails, the clamp is nailed to the base, after which the boards of the next row are inserted into the groove. Their fastening is carried out in a similar way.
3. If the last plank does not completely fit into the remaining space, it is cut to the required size and secured with nails or self-tapping screws.

Installation of tongue and groove boards is the most important stage in the repair process, because the strength and durability of the entire finish depends on the quality of the work. We hope that after studying this information, you will understand how to attach a floorboard and will be able to carry out all the upcoming work yourself.

Recommendations for installing floorboards

When arranging floors in a house, in addition to choosing the type of flooring, you need to be especially careful when choosing a method for attaching the purchased material. Each building material has its own fastening methods, including floorboards. Let's look at how to fasten floorboards using the most reliable and popular methods.

Methods for fixing floorboards

The floor covering experiences quite serious loads, so it is necessary to approach the choice of fastening method with all responsibility.

If some floorboards are not secured well enough, then after some time they will begin to loosen.

As a rule, this happens after a short period of time. The floorboards move, the initially flat floor begins to make an unpleasant creaking sound, and often it simply collapses.

There are several most common ways to attach floorboards:

• secret method, that is, the use of screws or nails;
• using glue;
• fastening with clamps.

Fixing floorboards with nails

In this case, the floorboard is fastened to a wooden base, which can be solid or made of joists.

The first row of floorboards is secured using nails, which are driven at a 45° angle through the tongue into the base. Then they are driven into place. You should pre-drill holes for fastening elements. This is done so as not to damage the ridges.

When adjusting the next row, the nails must be hidden. All subsequent rows of boards are fixed by driving nails through the surface.

When repairing a plank floor and replacing several floorboards, you need to ensure that all the floorboards end under the center of the crossbar. Otherwise, you may end up with a non-durable coating.

Glue method

If the floorboard is laid on a solid base, it can be fixed with glue. To do this, the grooves of the boards are coated with an adhesive, you can use regular PVA glue, and then they are placed on the tongues of the previous row.

The glue should be applied in a thin layer in 50 cm increments along the entire groove. The final tongue-and-groove edges should also be coated with adhesive.

Fastening with clamps

Some types of boards come with special clamps that fit into a slot on the inside of the board. These elements are designed to connect boards together. So, how to lay a floorboard using this fastening method?

To do this, you should adhere to the following technology:

• Waterproofing material is laid on the subfloor, which should be secured to the walls with construction tape.
• The clamps should be driven into the cracks of the boards laid in the first row using a hammer. This is done in the direction of the tongue.
• The ends of the planks are coated with glue, and then the first row is laid.
• Wedges about 1 cm thick should be inserted between the wall and the boards.
• Clamps are also attached to the second row of boards. The floorboards are secured in place by gently tapping a hammer through a block along the edges of the row.
• The remaining rows are laid out similarly.
• Then the wedges between the wall and the covering are removed.
• Installation of baseboards is in progress.

Special screws for floorboards

Professional craftsmen use special screws for floorboards to attach floorboards. The use of such fastening material allows you to obtain a reliably fixed floor covering with a fairly long service life.

Compared to conventional self-tapping screws, the cost of this type is an order of magnitude higher. However, in their properties they are more effective.

Special screws designed for floorboards have the following features:

• These fasteners are available in various sizes. Standard cross-section is 3.5 mm, length can be 35, 40, 45 and 50 mm. Depending on the thickness of the floorboards, the size of the screw is selected.
• This fastener for floorboards is not subject to corrosion, as it has a protective coating.
• There is a cutter at the end of the self-tapping screw, which allows it to be screwed into wood without pre-drilling holes. In addition, this structure allows the screw to fit more tightly, which means that the fixation of the floorboards to the base of the floor will be more durable.
• The self-tapping screw has a special milling cut. It has an angle at which the fastener easily enters the wood without splitting.
• Self-tapping screws for floorboards have another structural feature, which is the absence of threaded threads in the upper part. This design allows the floor covering to fit more tightly to the base.

Here are some tips on how to properly lay a floorboard:

• It is necessary to fasten the floorboards to the base using screws in increments of 25-30 cm.
• Some craftsmen recommend that before laying the floorboard and fixing it to the base, apply glue to it, which is used when installing parquet flooring.

  This option can be used if the waterproofing layer (for example, polyethylene film) was not laid. The adhesive fixation method cannot be used alone. It is used only as an addition to the main method of fastening using nails or screws.

  Why is the floor secured with nails and not self-tapping screws?

  Without them, it will not be possible to obtain a strong and reliable fastening of the floorboards (read: “How to lay floorboards - step-by-step instructions”).

• Along the entire perimeter of the room there should not be a tight connection of the boards to the wall. It is necessary to leave a gap between the wall and the floorboards of approximately 10 mm. It will act as an expansion joint.
• The screws used to install the plank floor can be completely hidden. To do this, the heads of the screws should be recessed into the wood by about 3-4 mm. The resulting holes can be hidden with pieces of wood that will match their shape and size. It should also be the same type of wood as the floorboards. Most companies that produce high-quality lumber complete their products with similar plugs.

The strength, reliability and service life of the floor covering will depend on how you lay the floorboard. Therefore, correct fixation of floorboards is a very important point in floor installation; therefore, it is worth approaching the choice of the method of fastening the boards with special care.

Self-tapping screw or nail, what to choose?

Unfortunately, the question that became the epigraph to this material, what to choose during construction, self-tapping screws or nails, is quite not idle and is known to many developers, when no one could really explain what exactly is needed? This question is not only not idle, but also does not have a clear answer at a time when some technologies will supplant others. However, the advantages of connections with nails or self-tapping screws can be considered when choosing one or another fastener depending on the type of work.

Pros of nails

The main advantage of using nails can be considered the centuries-old traditions of their use, which have revealed both the weak and strong sides of fasteners. When driving a nail, you can be sure that such a connection will last forever when cut, pressing the parts of the wood against each other, because The steel body of the nail is stronger than wood and is more likely to give way to vegetation than hardened forging or rolling. Even a connection that has become loose over the years due to swelling and shrinkage will remain reliable, meaning only a cut or shift, allowing the same house to change its geometry as it shrinks, while remaining a strong structure. Self-tapping screws also withstand large linear loads, which, however, are inferior to connections with nails. The reason for this is the smaller diameter of the screws and their increased hardness, therefore fragility, so the slightest weakening of the pressing forces entails complete destruction of the structure. In everyday language, nails can withstand wave loads, but self-tapping screws cannot.

What are the advantages of self-tapping screws?

The weak point of using nails is their unreliability from loads along the axis of the nail, the so-called pulling force; almost everyone has successfully pulled nails out of boards.

Fastening the floorboard, description of all available methods

You can combat this by driving nails in at an angle to the joint plane, or punching them through and bending them on the reverse side. Self-tapping screws in this regard have greater functionality, incredibly strongly pressing the parts being connected to each other. But even here, the tension in the metal of the screws can cause the opposite effect, when when the wood gets wet and swells, the caps come off, completely weakening the connection. By the way, when wood swells, very large stresses arise; in the old days, even stones were mined using this method by watering dry wood driven into a crack in a rock monolith.

Even if you decide to use self-tapping screws, most deviate from their installation technology, when you need to drill the part being pressed, countersink a hole for the head, and only then tighten the fasteners. We simply tighten the self-tapping screw without drilling and judge the amount of pressure by indirect signs, the depth of the head, completely ignoring the fact that even a gap may remain in the connection. When driving a nail, we know that 23 of its length should be in the monolith, and 13 in the pressed part, which is also true for self-tapping screws, but few of us choose them not only by length, but also by the size of the bare, without threaded part.

From all that has been said, simple conclusions can be drawn:

• It is still better to use self-tapping screws indoors, where there is less chance of moisture getting in and the loads are more defined and static;
• It is easier and more reliable to fasten sheet materials, for example, plywood, drywall, etc., with self-tapping screws, pressing them against frames or other load-bearing, stationary elements;
• nails remain a more reliable type of fastening of wood of external buildings, ensuring reliable and long-term operation, proven by time;
• In addition, where it is difficult to predict displacements, the same gate or light structure, the nails will be more durable.

Type of nails and choice of their size

When constructing wooden houses and temporary structures made of wood, any type of nails can be used (Fig. 1).

When choosing nails for building a house, you need to consider the following factors:

• whether the nails will be exposed to a humid environment;
• what materials need to be joined;
• what is the most suitable nail size;
• what is covered with the surface to which the structure is attached with nails (paint, varnish, putty).

When working with structural parts exposed to a humid environment, galvanized nails are used. The same nails are used in structures located in air or under a layer of water-based paint.
Different types of nails are used to fasten different materials. The length of the nail is chosen so that when connecting wooden parts it is 2.5 times the thickness of the material being attached. In such cases, as, for example, in fastening roof coverings, the length of the nail is determined by the depth of its entry into the wooden base. The minimum entry point for grooved nails is 30 mm.
Raw nails are used when fastening formwork, other temporary structures and parts of the frame that remain invisible (plugs, backing boards on the roof, etc.).
Connecting wooden parts with nails. As the nail enters the wood, it pushes the grain apart, which can lead to cracking. To prevent this from happening, nails should not be driven too close to the edge or end of the board (Fig. 2), and the spaces between nails should be large enough.

The susceptibility of wood to cracking when nailing is driven in depends on its moisture content.

Laying a wooden floor on joists

It is easier to hammer a nail into wet wood than into dry wood. Although green wood will withstand nails close to the edge, cracks will appear when the wood dries. Do not drive nails at the edges of thin and wide boards, as contraction stresses will cause cracks at the point where the nails are driven in.
Nails should be located in the shaded area. The distance from the edge depends on the thickness of the nail (Fig. 3). The nail size is indicated as follows: 75 (length 75 mm) x 2.8 (thickness 2.8 mm).

Fasteners for floorboards

You have decided to make a wooden floor, but you don’t know what fasteners to use for the floorboards, then use self-tapping screws to secure the floorboards.

Features of self-tapping screws for floorboards

For attaching floorboards, self-tapping screws are much better than a regular nail. After all, an ordinary nail can slip out of the board during its operation.

How to fix a floorboard

But a self-tapping screw screwed into the board will hold very well.

But there are different types of self-tapping screws, and not all of them can hold firmly in wood; flooring screws are suitable for this purpose. At the tip of such a self-tapping screw there is a special tip - a spatula; it is somewhat similar to the cutting edge of a feather drill. With the help of such a tip, the self-tapping screw is screwed into any type of wood, regardless of its density, and there is no need to drill out the wood first, it will not get stuck in it.

Wood fibers begin to weave into the helical groove, which is located on the screw shaft, and therefore it does not move when exposed to loads, both transverse and longitudinal. You can unscrew a self-tapping screw of this type only with a screwdriver installed in reverse.

For floorboards, self-tapping screws with a special hidden head are used; its diameter is three and a half millimeters, and the length ranges from thirty-five to fifty-five millimeters. This self-tapping screw will not split even a thin floorboard and will be able to pierce a fairly thick coating.

It is also worth paying attention to the coating itself. The coating provides a guarantee against corrosion of both the visible part of the cap, as well as the rod, which is hidden in the board. The screw is coated with a base of copper and zinc, and it is applied in a micron layer, resulting in every millimeter of the screw being covered.

How to attach a self-tapping screw to a floorboard

After we have figured out the types of screws, we move on to the process of installing the floorboard.

The floors between floors can be made of concrete slabs or beam structures, then they are sheathed with finishing and rough materials. For the rough layer, you can use planed boards, the thickness of which should be five centimeters.

After laying the subfloor, a thermal insulation layer is made, for which a polystyrene film is used, its thickness should be one and a half millimeters, and after that we proceed to installing the floorboard.

To attach the finished floor, as well as to make the sheathing of the subfloor, floor screws are used. You can either fasten it through the boards so that the self-tapping screw pierces the plane of the flooring in a pre-drilled hole, and then it is hidden with a “hatch” of the same color, made of the same wood, or through the edge of the tongue-and-groove lock, which is located at the side end of the floorboard.

But it is best to use the through-fixation method, it is much simpler and the work will be done much faster.

Fastening the board in practice, what it looks like

After the thermal insulation is installed, it is necessary to arrange the boards along the wall and lay them end to end. We do this so that a gap is formed between the very first row of the floorboard and the wall. this gap is then closed with a floor plinth.

Now the boards of the first row are laid along the wall and mounted with emphasis on the masonry located at the end. We lay the next row at intervals, the seam must be covered with a whole board from the previous row. After about the fourth row, all the boards need to be knocked down and moved towards the wall, and now we make secret holes, fix the boards with self-tapping screws and seal the fastening points. We screw in self-tapping screws every forty centimeters, but not less than two screws on one board.
