Each time, when floating laying of a parquet board is meant, it is an accelerated and simple installation, which is easy to do with your own hands. What features does the technology have and what stages does the process of flooring in this way consist of? About it below.

Floating laying is probably the easiest way to lay a parquet board.

“Floating” styling: features and advantages

A distinctive feature of the technology is the connection of the dies on the principle of a thorn groove without fastening to the base with glue or self-tapping screws. Almost all types of flooring, available for sale today, are equipped with a system for laying exactly the floating way.

Installation in the tongue-and-groove is rightly considered one of the most technologically advanced, and therefore widely used. Nevertheless, there is one nuance that owners of large premises need to remember. The larger the floor area, the more stiffness the base will require, so the floating method will have to be improved, additionally using adhesive compositions.

Laying on glue is not much more difficult, the main thing is to choose the right glue

Fastening lamellas within the framework of the technology becomes possible due to the presence of special fasteners - grooves and ridges. The main advantages of the method include the following points:

  • the connection does not weaken during operation, while maintaining reliability,
  • the temperature level does not affect the strength level,
  • floor loads will not reduce the stability indicators of the coating,
  • installation is quick and easy,
  • The "human factor" is reduced to zero due to the maximum reasonableness of the system,
  • the canvas looks unified.

In addition, as noted above, laying parquet floating method does not require special experience, knowledge. If necessary, everyone can mount the floor, if they follow a simple proven algorithm.

How to lay a parquet board “floating” method: instruction

So, the basis of the technology is the fastening of boards together using a special lock connection. Lay the material on a substrate and a previously prepared (aligned, peeled) base. Act in the following sequence:

  1. A waterproofing layer is arranged using a film with a thickness of 200 microns, overlapping strips with a margin of 15-20 cm and fastened with tape.
  2. At the wall they also make an inlet of no more than 15 cm.
  3. For the device of the substrate, cork or foamed polyethylene is used, which is placed on the waterproofing film.
  4. Count the number of rows of the board.
  5. To ensure tight contact of the board with the wall, the tenon is cut in advance, leaving a gap between the wall of 10-15 mm, driving in pegs.
  6. Laying is carried out in rows with finishing the board with a hammer through a wooden block.

The plinth is laid after the installation of the floor. It will mask the indentation between the walls and the floor. The baseboard is fastened with kleimers with indents of the first 15-20 cm from the corner and the rest in increments of 40-50 cm.

It is better to have a stock of parquet boards in case of damage during installation

Possible difficulties in the process of installing the floor

Laying the floorboard with the floating method, although a simple, quick process, has its own difficulties. One of them is the installation of boards in the location of the pipes of the heating pipe, the doorway. To ensure that in these areas the coating is as smooth and stable as the rest of the zones, you need to delicately trim the boards with preliminary marking on their surface, with holes several millimeters larger than the diameter of the pipes and removing part of the panel in the center from the holes.

Finished boards are stacked with the plant of the cut part for the pipe. To fix the dies, use glue, processing joints in areas with cut parts. For aesthetics in the zones of pipes, plugs are installed to match the color of the parquet board.

Additional tools may be required to cut holes.

Floating floor - what is it (design and device)

Laying the top layer of plates is carried out so that the lower seams overlap by at least 7 cm.

Building boards should be tightly pressed one to one. Tight compression is achieved by inserting wedges into the compensation clearances. Wedges are removed after the glue dries, which grease the edges of the plates before laying.

The final stage of the technology for laying a floating floor with a dry screed is the device of the final floor and the fixing of skirting boards.

Carrying out these operations does not differ from the operations described in the article “The device of a floating floor with a monolithic screed”.

Floating floor on logs, laying technology

The floating floor on the lags is mounted much like the floor described above. For him, a characteristic feature is the lack of contact between the floor frame and its components with walls and supporting structures of the ceiling.

The overlap is leveled, the building film is laid.

Then logs are laid in such a way as not to cut the insulation boards. This not only saves material, but also speeds up work.

The lag section is selected depending on the step of the lag and on the span. To select a section, you can use the table

Log section, Span, m at step lag, mm
300 mm 400 mm 600 mm
50×150 3,30 3,00 2,61
50×200 4,30 3,95 3,40
50×250 5,50 5,00 4,40
50×350 6,70 6,10 5,30

Compensation tape is glued along the walls and around the pipes.

The tape is laid under the lags. Logs should not come into contact with walls or between each other.
Insulation plates during installation should fit snugly to the lags.

They are also stacked tightly to each other. For this, the width of the material should exceed the distance between the lags by 1 - 2 cm.

With the help of screws, plywood or chipboard is attached to the lags. Screws are placed two centimeters from the edges of the plates every 30 cm.

The final step in the technology of laying the floating floor will be the installation of the final floor.

The advantages of a floating floor

Why create floating floors that are complex in design if there is already a time-tested concrete screed?

This is primarily due to the high soundproofing properties. This is facilitated by the independent position of the floor covering in relation to the base and walls.

Equally important is the ability to make good thermal insulation in it. This is especially true for the first floors.

The third advantage is the ease of installation (if you use a dry screed or when installing a prefabricated floor)

In addition to the listed advantages, several more can be distinguished:

  • multi-layer floating floor screed provides strength and rigidity,
  • good heat and sound insulation
  • depreciation effect, which positively affects the musculoskeletal system,
  • simplicity in leaving.

Most residents of apartment buildings suffer from shock noise. It occurs when walking fast, jumping, from rearranging heavy furniture, etc. Interfloor floors made of concrete slabs are not able to absorb it. The best option would be to install a floating floor, which is able to improve the sound insulation performance of an apartment by almost 50%.

He will not require special care during operation. It is washed, vacuumed and wiped, like any other floor covering.

Floating Floor Designs

There are several main types: prefabricated, cork, concrete and dry screed. Let us consider in more detail each of them.

Prefabricated Floating Floor

This type includes floors made of laminate, grooved boards, as well as parquet, so it is also called a wooden floating floor. Before proceeding with its installation, the materials must lie for some time in the room in which they will be laid.

One of the most important conditions for a quality floor is the evenness of the base. If it has minor scratches, chips or any other minor flaws - this is not a problem. But if the base has significant irregularities, then its service life will be sharply reduced.

Check the evenness with a two-meter rail or rule. By attaching the rail to the floor, you can see if a gap has formed.

Floating cork floor

For it, multilayer panels are used, the top layer of which is made of natural cork. Each such panel has its own unique pattern. They do not have fasteners with a base, but only connect to each other using the groove-comb system, the joints of which are treated with moisture-resistant glue. If necessary, they are easy to dismantle and shift elsewhere.

Dry screed

It is the creation of the basis for the finish flooring. It should have good sound and heat insulation properties. Therefore, you need to choose the material for it, depending on the necessary goals. So, for good sound insulation, you should opt for mineral wool, which has the highest noise reduction index. And the foam plastic will do the job of warming well.

Concrete floating floor

It is the most durable of all types of floating floors. Therefore, it is often used where there are large loads on the floor: in warehouse and industrial premises. But in private homes, it is not uncommon, as it is reliable and durable.

  • even base
  • thermal insulation material
  • waterproofing
  • screeds
  • insulating tape.

When laying such a floor on the ground floor, it is necessary to lay waterproofing material. In addition, along the entire contour of the room, an edge insulating tape is mounted. The screed is poured from high-quality concrete using a reinforcing metal mesh.

This type of floor will need to install heating circuits. It does not matter whether it will be a water heated floor or electric, the main thing is that it should be.

Floating floor technology

The design of the floating floor consists of 3 main layers.

Base. The main condition is that it must be tough. It can be a concrete screed, reinforced concrete floor or wooden floors.

Lining layer. This is isolon, polystyrene, expanded clay or mineral wool. The type of substrate is selected not only on the basis of the technical characteristics of the material, but also on the basis of the quality of the hard base. For an even base, sheets of foam, isolon, foil isolone or linoleum are suitable. If there are significant irregularities, then they can be corrected with expanded clay. But when using it, it is recommended to lay an isolon or any other vapor-proof material between the expanded clay layer and the base.

Flooring. This is the top floor covering, the elements of which are attached only to each other. When laying it, regardless of the material, it is necessary to leave a gap around the entire perimeter, between it and the wall of 10-15 mm.

How to make a prefabricated floating floor with your own hands

Before you make a floating floor, you need to level the base. There is no need to make a concrete screed to lay a laminate or sheet pile. It is enough that it does not have differences and other irregularities. It can be laid on the old floor, as long as it is even. Consider its installation on the example of a laminate.

As the substrate, you can use an isolon or a thin roll cork. Of the tools useful: tape measure, hammer, pencil, metal saw or jigsaw.

All boards are attached on four sides to each other according to the groove-comb system with a hammer. You can start laying from any direction, but in such a way that the panels are perpendicular to the window, in this case the joints will be hardly noticeable. A substrate is laid in one row on the prepared base, a series of laminate boards are laid on it, along the wall. In this case, do not forget about the gap between them and the wall. All boards are fitted with a hammer, the main thing is not to overdo it and knock gently. At the end of the row, the board is cut to the desired size. All subsequent rows are staggered. At the end, skirting boards with cable channels are installed.

How to make a cork floating floor

Floating floors from cork panels can be mounted on an existing linoleum or carpet. But only if their surface is perfectly flat. In this case, it will be enough just to dismantle the baseboard.

If laying on a concrete screed, it should be smooth, dry and clean. Then a thin substrate is laid on it, the distance between the strips of which should be 1-2 cm. A distance of 1-2 cm is also left between it and the walls.

A cork is a hygroscopic material, therefore a layer of waterproofing material is required (vapor barrier or polyethylene film, isolon). Waterproofing must also go on the walls of the room to a height of 5-10 cm.

It is desirable that cork panels are oriented in the direction of sunlight. Laying is done from right to left, in this case the comb will be directed towards the wall, and the groove inside the room. Thus, the entire first row is mounted along the wall. It should be calculated in advance so that the length of the last panel is not less than 20 cm. You can start a new row with the remainder of the last panel of the previous row. During installation, the joints should not coincide with each other.

After the floor is laid, it is not recommended to put heavy objects on it for a week.

How to make a dry screed

This type of floor alignment is the most common. This is mainly due to the ease of installation and low cost of materials. After its installation, it is not necessary to allocate time for drying, but you can immediately start finishing work.

Also, unlike concrete screed, it is lightweight and can be used without load on the supporting structure of the building. Its only drawback is low moisture resistance, but this problem can be dealt with using high-quality waterproofing materials.

Most often, a dry screed consists of two main layers: a dry backfill and sheet material that covers it. Silica or quartz sand, perlite sand or expanded clay are used as backfill.

This stage not only levels the floor, but also creates good sound and heat insulation. From above, sheet material is attached to it, for which GVL, chipboard, plywood and other sheet materials are suitable.

For vapor barrier between the backfill and the base, a plastic film is laid with an overlap on the walls. Joints should be glued with reinforced tape.

Then soundproofing is done. To do this, a strip of mineral wool, isolon or polystyrene 0.5-1 cm thick is laid along the perimeter of all walls.

Backfill is carried out by lighthouses, which are subsequently cleaned. It is evenly distributed on the floor and carefully packed. It is advisable to fill up in small areas to avoid the possibility of further curvature of the floor covering due to uneven settlement.

The sheet material is staggered along the surface. Between themselves, the sheets are attached using self-tapping screws.

How to make a concrete floating floor

It is made both in private houses, or apartments, and in production and storage facilities. It is resistant to temperature extremes, strong and durable, and also has good sound and heat insulation properties. You can make it yourself, in this case, the price of a floating floor will be significantly lower.

If the floor is mounted on the ground floor of a house or in industrial premises, then it is necessary to lay waterproofing material that is mounted on thermal insulation: polystyrene foam, dry backfill, polystyrene foam or mineral wool.

When all insulating materials are laid, a contour tape is fastened around the perimeter of the room, which will prevent the walls from touching the floor structure.

After the tape is installed, filling begins. For this, concrete mortar is used. The higher the grade of concrete, the better the screed. Filling is done on pre-set beacons using reinforcement or reinforcing mesh.

After pouring, the concrete floor must be allowed to dry.

  • It is advisable to lay the floating floor at room temperature and in dry conditions.
  • It can not be additionally fastened with screws, nails or glue.
  • If a prefabricated floor is laid, prefabricated panels must lie unopened at room temperature for some time.
  • Laying is carried out strictly perpendicular to the windows and with a gap between the walls.
  • After installation, let the floor stand for 6 hours, and only then install the skirting board.
