Laying the csp on a wooden floor. DSP board and its application for leveling the floor - material characteristics, pros and cons, installation technology. Basis for lag

The use of DSP slabs is important for the construction of the floor surface, especially if you need to make the floor level as soon as possible. It is this building material that helps to speed up DIY repairs. Due to the fact that the building material is natural, it is environmentally friendly and clean. In addition, DSP is quite inexpensive, and the floor surface is durable, beautiful and durable.

DSP board consists of 65 percent cement, 24 percent wood chips, 8.5 percent liquid and 2.5 percent impurities, which are similar to liquid glass and aluminum. It is the cement that gives the building material reliability and the longest possible service life. The usual size of a cement-bonded particle board is 320 × 125 cm, and the thickness can be from 1 to 4 cm. However, the dimensions may vary. A special indicator for this building material is density. It should be no more than 1300 kg per m2, and the humidity should be about 6-12 percent.

If the plate is in contact with liquid for a day, then the canvas should not swell by more than 2 percent.

The surface of the DSP is rough, it depends on the method of grinding. But if the roughness is not more than 80 microns, then the use of grinding can be avoided. Due to the fact that you can choose a material, the thickness and smoothness of which is certain, it is possible to solve the problems posed during the decoration of any room.

In addition, there are other benefits.:

High reliability. The strength is good due to the multi-layered material.
Long service life.
The material is very elastic because the 2 outer layers are made of small chips, and the longer particles are located inside.
It is not necessary to level the DSP, the boards are smooth
Environmental friendliness.
Fire resistance. DSP contains additives that reduce the risk of fire.
Resistant to mold, fungi and rot.
High moisture resistance.
Resistance to temperature extremes.
Resistant to abrasive substances.
Easy styling.
High sound insulation.
Affordable cost.
Waterproofing.

Of the shortcomings, we can talk about the large weight of the material and the inconvenience in the cutting process due to the strong dustiness. But, the advantages naturally outweigh the disadvantages, so an increasing number of consumers prefer to choose and install the material at their facility.

Simple installation of cement-bonded particle board on a wooden floor

Due to its unique performance properties, cement-bonded particle board can be a substitute for concrete screed. The screed is difficult to fit, and the dry plate is mounted very quickly and is convenient to work with. Such a canvas is durable, since it has the highest ability to withstand serious loads.

It is necessary to choose slabs in terms of thickness, the greater the permeability of the room, the thicker the material should be.

However, despite the fact that the characteristics of the material are unique, to complain about the excellent performance, it is important to put the plates correctly. This is the only way to preserve all the positive qualities and functions of the building material.

The use of cement-bonded particle board is possible for:

Thermal insulation of buildings.
Interior decoration.
Outdoor work.

In addition, today DSP is often used for finishing the floor surface. It is possible to arrange this building material in rooms with a high level of moisture. Typically, a cement-bonded particle board is laid under tiles or porcelain stoneware.

This is due to the fact that it is porous tiles or porcelain stoneware materials that require a flawlessly even base.

Even the smallest bump or dimple can cause cracking on the surface of the topcoat. Also, floor coverings made of cement-bonded particleboards are used to create 3D structures, because in this case, a reliable rough base is needed. And if we consider the solution with the installation of the "warm floor" system, then at the same time there appears both a perfectly smooth surface and good thermal insulation, which will retain heat, not allowing it to leave.

DSP on the floor on the lags

There are 2 requirements for a wood bar: it must be thoroughly dried and must be treated with an antiseptic so that rot and mold do not develop later. Instead of a store-bought product, it is possible to use treatment with used engine oil.

This event has 2 advantages: low cost and no foreign aroma.

If the floors made of CBPB are laid on cement, then the cross-section of the bar can be reduced to 50 by 50, so as not to take away precious centimeters from the premises. When arranging the overlap, it is necessary to observe the horizontal level of the wood logs. The first bars are arranged on two opposite vertical surfaces, and a fishing line is stretched between them.

The distance between the lags should be about 50 cm. Further, at the same distance, it is necessary to fix the ribs for the transverse lathing. It is necessary to fix it on self-tapping screws or dowel-nails, and for strength, plywood or gypsum fiber board should be attached to the logs. Then you can install the insulation.

For this, you can use any thermal insulation material.:

Styrofoam.
Foil-clad polypropylene.
Cork.
Minvata.

They begin to arrange floors along the logs from DSP, distributing the sheets around the perimeter of the room. The sheets to be cut are marked with a marker using a ruler. It is good to cut the material with a grinder, but if it is not there, then you can use a hand hacksaw.

The material is easy to cut, but it is dusty, you have to wear a mask. The floors along the logs are mounted from DSP with a mandatory breakdown at the seams.

The sheets are attached to a wooden beam with fasteners, and the distance between them is subsequently putty or closed with a special tile glue. It is not uncommon for bumps to form at the joints of DSPs, which will further adversely affect linoleum or cork coatings. These defects can be removed by sanding and filling the individual areas of the floor. It is good to treat the top with a substance with a waterproofing effect, especially if the floor is laid in a room with high humidity.

Dry screed on a wooden floor

In fact, installing a screed on wooden floors is not even very difficult.

A sealant is used as the bottom layer - it can be:

Building mixture;
Mastic;
Traditional PE film.

Next, a reinforcing mesh is installed on top of the sealant, which is then poured with a mixture of cement to a level that is marked in advance on vertical surfaces. All measurements and marks must be made with the help of special construction tools, otherwise the screed will not turn out even, and it will not be possible to cover the DSP, and even more so the finishing coating. In order for the surface to be flat, the mixture must be well leveled, immediately after pouring, but before installing the coating, it is necessary to thoroughly prepare the wooden floor. Antiseptic treatment, cleaning, grinding.

So, for repairs inside, it is best to use smooth slabs, since they are easy to paint, plaster, etc. DSP is a versatile building material that is used for construction and decoration of not only warm, but also cold rooms.

Leveling the subfloor for the decorative topcoat can be done in more than one way. Cement screed for this case is the most laborious and time consuming process. Often, chipboard sheets are simply laid on the base. This material shows its weaknesses both in the process of working with it and in subsequent operation. Chipboard has a fair amount of fragility, the property of breaking at the ends and corners of the sheets when cutting and fastening. Floors with such a base do not tolerate excess moisture, therefore they are not suitable for bathrooms and kitchens.

Due to its strength, density, environmental friendliness, resistance to moisture, fire, decay, chemicals, DSP is considered one of the best sheet building materials and is an excellent basis for a subfloor.

For those who are already familiar with a relatively new building product - DSP, the question of choosing a material for a rough base disappears by itself.

Characteristics of cement-bonded particle boards

This product does not possess complete perfection, but it has undeniable advantages that make it more and more popular among repairmen and builders. If we compare its mechanical strength with chipboard, then the result will be 3 times higher. DSP has a very high resistance to physical influences of any kind, immune to fungal infections and mold. These boards do not have the main disadvantage of chipboard - hygroscopicity. The ability to completely withstand a humid environment and critical temperatures, absolute incombustibility and an affordable price allow you to put up with the heavy weight of cement-bonded particle boards and the rather dusty process of cutting them during operation.

The technology for the production of CBPB completely eliminates the formation of voids and internal defects in the body of the slab. The three-layer structure determines the extraordinary strength of the material made from small chips and wood fibers, Portland cement and plasticizers by pressing. The specificity of the composition and production of cement-bonded particle boards allows them to be used in a wide variety of areas of construction and repair: from the construction of buildings to the interior and exterior decoration of premises. The best option, in order to level the floors in a new building or during the construction of a house, would be to use DSP laying along the logs. In the process of working with plates, another advantage of the product will appear: convenient installation, ease of cutting, drilling and fastening.

Preparation for the installation of a DSP coating

Regardless of what type of base the floors will be laid on - reinforced concrete or soil, it must be sufficiently reliable.

In the case of preparing the base for a new floor on the first floor of a private house building with open ground, the earthen surface is initially leveled. On it, a loose cushion of sand and gravel mixture with a thickness of about 20 cm is arranged and compacted very well.
Supports for logs in the form of pillars (or strip foundation) can be laid directly on the ground, but an additional layer of hydro and thermal insulation will not be superfluous. Brick pillars are laid out in the form of a well, reinforcing their inner part and making concrete pouring. The distance between the supports can vary from 50 cm to 1 m and depends on the size of the section of the timber from which the logs will be made. Then waterproofing is attached to the supports.

The concrete base is checked for horizontal deviations. If the indicators do not exceed 3-4 cm, then the floor is considered suitable for further work, and minor differences are eliminated by placing compensating gaskets under the lags. With serious surface irregularities, it is better not to save time and money, but to make a cement screed. Otherwise, this will lead to a violation of the stability of the subfloor and its premature repair and replacement of the decorative coating.

To install a log for a floor made of cement-bonded particle board, it is necessary to use dry and antiseptic treated bars with a section of 100x50 mm or 150x100 mm.

All damage to the concrete base in the form of cracks and pits must be filled or repaired with cement mortar. Waterproofing can be done by laying a thick plastic wrap with a slight overlap from the floor to the walls.

In the work on the device of a rough coating of cement-bonded particle boards, you will need:

wooden beam with a section of 150x100 or 100x50 mm;

antiseptic solution for wood;

a hacksaw with fine teeth;

waterproofing;

insulation;

nylon fishing line;

ruler, felt-tip pen;

dowel-nails;

self-tapping screws;

drill;

sander;

leveling putty.

Laying DSP on logs

There are 2 requirements for the timber: it must be well dried and must be treated with an antiseptic to prevent putrefactive processes and protect against mold and mildew. Instead of a special tool, you can use the processing of engine oil, which has 2 advantages: low price and no foreign smell. If the floors made of cement-bonded concrete are arranged on a cement screed, then the cross-section of the timber can be reduced to 50x50, so as not to take up the usable space from the room.

It is important to observe a strict horizontal level when installing a lag. The first beams are mounted on two opposite walls, and a fishing line is pulled between them. Lags are stuffed with a distance of 40-50 cm, the most suitable for installing sheet chip materials. Then, with the same pitch, the ribs are attached for the transverse lathing. Fixation takes place using self-tapping screws or dowel-nails, and for strength, small pieces of plywood are laid between the concrete and the timber. After that, you can start installing the insulation. For this, it is possible to use any type of insulation: from polystyrene and foil-clad polypropylene to mineral wool and cork.

They begin to lay the floors along the logs made of cement-bonded particle board, distributing the sheets around the perimeter of the room. The elements to be trimmed are marked with a felt-tip pen using a ruler. Cutting DSP sheets can be done with a grinder, but with the help of a hand hacksaw, they are divided into parts quite simply. A hacksaw blade draws a furrow along the line of the markings made, and part of the plate easily breaks off in the right place when pressed.

The floors along the joists are laid from cement-bonded particle board with obligatory separation at the seams. Plates are attached to a wooden beam with self-tapping screws, and the gap between them is subsequently closed with putty or tile glue. Often, bumps form at the joints of the slabs, which later have a bad effect on floors such as linoleum or cork: irregularities appear through the flexible surface. These shortcomings are eliminated by grinding and filling certain areas of the floor. It is advisable to treat the top layer with a composition with waterproofing properties, especially if the humidity in the room is above the normal range.

Quite often today, DSP is used for the floor. The use of DSP slabs is important for the construction of the floor surface, especially if you need to make the floor even as soon as possible. It is this building material that helps to speed up DIY repairs. Due to the fact that the building material is natural, it is environmentally friendly and clean. In addition, DSP is quite inexpensive, and the floor surface is durable, beautiful and durable.

In this article, we would like to talk about the technology of laying on the floor such a material as DSP - cement particle board. A little about the material itself. In appearance, it looks like flat slate, except that it often has a much larger sheet thickness, and the sheet size is larger. DSP differs from slate in that it is based not on asbestos, but on ordinary sawdust and cement.

But the article is not at all about the material, but about its installation (if necessary, you can read all the necessary information in the article: where you will find not only a description of the material and the technology of its production, but also the positive and negative characteristics, pros and cons of this building material. ).

1. Cement-bonded particle board laying on a wooden floor.

We note right away that it is possible to make an excellent base, for example, under a wooden floor, with the help of DSP. In this case, there is no need to shift the boards.

1. Securing the base.

To begin with, we additionally fix all the boards so that they do not creak. It is best to do this with self-tapping screws. For our purpose, galvanized universal screws 4x51 are suitable. Pre-drill the boards directly above the log with a 3 mm drill and tighten the screw. This strengthens the entire floor.

2. Drawing up a plan.

Next, we draw up a plan for laying the slabs. To do this, we measure the size of the room and the size of the DSP sheets, after which we draw a plan on a sheet on a reduced scale. Try to keep the long sides of the slabs across the planks on the floor so that the final surface is smoother. Of course, it will not be possible to close everything with whole plates, you will have to cut one or more. Based on the plan, we determine the size of the pieces of slabs.

DSP slabs are cut with a conventional grinder, although you can also do this with hand tools - for example, a hacksaw. The main thing is that the cut runs perpendicular to the sides, otherwise the seams between the plates will turn out to be uneven. In the process of drawing up the plan, it is necessary to take into account that a small gap will remain between the slabs, therefore, it is better to cut the pieces necessary in size as needed during the flooring process.

3. Laying slabs on the floor.

We start laying the slabs from the corner of the room and move to the opposite corner. Initially, whole plates are put, and where it is not included, they are supplemented with pieces. Leave a small gap of 2-3 mm between the plates. We fasten the CBPB boards to the floor with galvanized self-tapping screws through the wooden floor to the joists. In this case, the dimensions of the screws are selected based on the thickness of the floor and DSP boards so that the screws go into the logs by at least 30 mm. Previously, in the places of attachment of the DSP slabs, they are drilled to the thickness of the self-tapping screw, taking into account the thread. The self-tapping screw must enter the plate freely. The inlet hole in the slab can be slightly widened with a larger drill. This will completely hide the screw head.

4. Final finishing.

After the floor is laid, we seal all the seams and attachment points with the help of a putty or sealant. By the way, silicone sealant will not work in this case. It tolerates dynamic loads extremely poorly and begins to lag behind the adjacent surface. It will be better to prime them before sealing the joints. Any deep penetration primer is suitable for this.

2. DSP laying on the floor from a metal profile.

Finishing floors with DSP is an excellent way out for those who make a trailer or stall with a metal profile frame. First of all, this is determined on the basis of such qualities of cement-bonded particle boards, such as good strength and inertness to moisture. It is possible to lay DSP on a metal profile without an additional base, directly fixing the sheets with self-tapping screws for metal of sufficient length. At the same time, if there is a need for floor insulation, you can initially fix wooden bars along the metal profile, between which you put cut insulation plates, for example, mineral wool, and cement slabs of DSP to the bars.

In fact, the styling technology is no different from the one described in the first part of the article, so we will not describe it in detail. Note that if you will attach the sheets directly to the metal profile, then you will need special metal screws. They usually have a different head design and it will be somewhat more difficult to hide them so that they do not protrude above the surface of the slab.

When arranging, one of the most important points can be considered the issue of choosing a coating. In these rooms, there is a lot of humidity, water often appears on the floor, and this can result in swelling, mold, and cracks. As a result, the owner has to either change the coating or spend money on its repair. Today, there are many options to avoid such problems. Renovation professionals often use cement bonded particleboards. What are their characteristics, what are the uses, pros and cons of use, how suitable they are for the bathroom floor, reviews - read about all this further in the article, watch the thematic video.

The main characteristics of cement-bonded particle boards (CBPB)

With the current rich choice of building and finishing materials, the eyes of the townsfolk sometimes run up, and it is rather difficult to dwell on this or that product. To facilitate this task, we present a list of DSP characteristics:

under warranty, the stove must last 50 years (in an aggressive environment, without additional protection, about 15-20);
product density 1300 kg / m3, hardness 55 MPa;
fire resistance (for almost an hour, a cement-bonded particleboard can withstand the effects of a flame, not allowing the fire to spread);
low level of moisture absorption;
zero toxicity level;
ecological cleanliness;
high reliability.

DSP has a high degree of environmental friendliness

DSP slabs are intended specifically for rooms with constant humidity, the advantage of this material is that both a specialist and a layman can work with it. The use of such a stove can both speed up and significantly reduce the cost of work on the arrangement of a bathroom and a toilet. In addition, this material is resistant to mold and various fungi.

Advantages and disadvantages of the material

Cement particle boards have the following advantages:

strong and durable;
resistant to temperature changes;
excellent decorative properties;
the possibility of finishing with any materials;
simplicity in working with the coating, its processing;
adequate price;
lack of decay processes even with constant contact with water;
fire resistance due to the presence of cement in the slabs.

There are, of course, some disadvantages in the use of plates:

during installation, without proper skill, a plate of small thickness may break;
the coating has a high density;
the slab weighs quite a lot, so it will not be suitable for cladding high walls.

These disadvantages are insignificant, therefore this material is in great demand.

Please check quality certificates before buying

Cement particle board is a practical, modern, profitable material that solves many problems. But it must be used correctly. Here are some tips to help you work with these cookers:

When drilling holes, it is necessary to indent from the edge 2-3 cm, not less, then the plate will not crack or crumble.
If the plate is fixed to any surface other than wood, only metal self-tapping screws should be used.
You need to be very careful when working with these slabs, the DSP material can be quite fragile.
Before final finishing, the slab must be primed.
If it is necessary to cut the slabs into certain fragments, then it is necessary to use a special cutting tool with a diamond coating.

Considering all the above information, we can say that DSPs have occupied their niche in the construction and finishing industry. They are practically indispensable for the construction of sub-floors made of wood, ideal in rooms with constant humidity and sharp temperature fluctuations.

Due to the high strength of the plates, in bathrooms with such a floor and finish, you can easily install any type of bath, drying, large, other things irreplaceable in the household. They can also be used where there is a likelihood of subjecting the flooring to significant mechanical stress. Another advantage of DSP is its good soundproofing qualities. The aesthetic qualities of the slabs are also excellent, while they are undemanding to care for, they are very easy to wash and clean.

Cement particle boards are widely used as a substrate for various facing materials, such as mosaics, tiles, natural stone. They are also used in the arrangement of "warm floors". The minimum thickness of the material with its high strength allows it to be used without losing the height of the room.

Tools required for the installation of cement bonded particleboards

adhesive for tiles or other cladding;
primer;
screws, self-tapping screws;
reinforcing tape to join the plates.

Attention! Before laying, all sheets must be carefully prepared and measured so that they fit the parameters of the room being repaired. Sheets must be laid out, carefully adjusted and marked so that they do not get confused during the finishing installation.

According to user reviews, the slabs are very convenient when installing the floor, especially when it is necessary to shorten the time of work. Many people praise the versatility and resilience (the two outer layers are made of shavings of the minimum size, and the inner one is made of longer and larger ones). Consumers also appreciate the perfectly flat surface that these plates can provide. They can easily replace the concrete screed we are used to.

DSP is perfect for bathroom floors

DSP selection

When purchasing plates (in fact, this applies to all other building and repair materials), you must definitely check the availability of the necessary certificates. It is better to buy DSPs from large reliable manufacturers, then there will be no doubts about the quality and compliance with all standards.

Advice. Many manufacturers of building materials have a good system of discounts for wholesale buyers, which means that you can save a lot by calculating in advance how much material you need and make a one-time order at the best price.

During the production, no dangerous impurities and chemical compounds are used, such as formaldehydes, harmful resins, etc., so the material should not have any sharp extraneous odors.

Advice. The thickness of the slab is chosen depending on the needs. It is better to consult either a store or a specialist in repair and decoration.

In any case, cement-bonded particleboards are an excellent choice for decorating bathroom floors, and the information in this article will help you navigate. Watch a thematic video and use only the best materials for repairs!
