DSP plate on logs in a wooden house. DSP slabs for the floor: application, cement slabs on a wooden floor, cement chipboard, warm floor on a DSP for tiles on logs with your own hands, photos and videos. DSP in insulation works

Today, the DSP-plate has gained popularity: the use of this material for the floor is very convenient. This is due to several reasons, the first of them is the absolute environmental friendliness, the second is the low cost. At the heart of the plate are exclusively natural raw materials. The connecting components are minerals that do not emit poisons and trace elements during operation that would be dangerous to human health. Among the ingredients of the canvas, wood shavings, water, Portland cement, as well as special additives can be distinguished. In the production process, the listed components are combined and go through the pressing stage.

The use of DSP for the floor

Today, finishing with DSP slabs of the floor area is quite common. This material is characterized by excellent thermal insulation properties, moreover, it can be used in conditions that differ high humidity. After laying the slab, it will be necessary to protect it with a primer or water-repellent mixture. The canvas will last for a long time, as it is able to withstand heavy loads. Depending on what kind of traffic will be in the room, you can choose plates with a more or less impressive thickness.

Despite the fact that it has excellent operational use for the floor, it must be accompanied by compliance with all installation rules, only then will it be possible to maintain all the qualities of the material. With this plate, you can short time make a perfect leveling of the floor surface. The use of this material allows you to reduce the period of work. The floor will be strong and reliable, and construction costs will be significantly reduced.

Characteristics of the DSP

The composition of the material is 24% 8.5% liquid, as well as 65% cement, which ensures the durability and strength of the slab. In addition, among the ingredients there are 2.5% hydration impurities by type and Depending on the parameters of the floor, you can choose plates that have dimensions equal to 3200 x 1250 mm, while the thickness can vary between 10-40 mm. But, according to the standards, the plate can be made with other parameters, the deviations depend on the thickness.

Density and surface features

Considering DSP properties- plates, it is worth paying attention to the density, which should not exceed 1300 kg / m 2, while the humidity can vary between 6-12%. When exposed to water for 24 hours, the canvas should not swell by more than 2%, and the plate can absorb moisture in a volume of approximately 16%. Tensile strength is 0.4 MPa.

The surface of the material should be rough, and the degree of roughness will be affected by the grinding method. If the manufacture is carried out in accordance with GOST 7016-82, then the roughness of the plates will be more than 320 microns, but the canvas may not be polished, then this figure is within 80 microns.

Varieties of DSP

DSP-plate, the use of which today, as already mentioned, is becoming more and more popular, is produced on modern equipment in several varieties. These are, for example, plates, the thickness of which is only 4 mm. The resulting material does not imply the need for grinding, which, when carried out, causes an increase in cost. Increasingly popular plates that have a smooth embossing. They contain small elements, the size of which increases closer to the center of the canvas. With the use of such material, you can get a floor that will look like natural stone. That is why the canvas after laying does not need to be additionally finished.

Advantages of DSP over other materials

If you have not yet decided which flooring will be laid on the floor: fiberboard or DSP-plate, the use of these materials for the floor, or rather, their quality benefits, should be considered in more detail. Despite the fact that in the market of modern building materials presented a great variety of plates for carrying out repair work, the DSP can be considered the leader. So, if we compare a DSP sheet with a fiberboard web, then the first one is much stronger. In addition, cement particle board has such a quality as frost resistance, which allows the use of this material as a floor covering in houses that are not used for a whole year, but only during the warm period.

If you need a sufficiently strong surface, then you should choose a DSP: a cement-bonded particle board just has such qualities, they are due to the fact that the web is based on three layers, two of which (outer) are made of small chips, while the inner one consists of longer particles. This gives the material elasticity, high density and hardness. Do not be afraid that the plate will delaminate during operation.

Preparatory work

DSP-plate, the use of which is considered in this article, involves the use of self-tapping screws when working with it. You can purchase canvases with a thickness in the range of 1-1.5 cm. As rough coating it is acceptable to use wood or concrete screed. If there are logs on the floor, then DSP installation can be made on top of them. It is recommended to cut the material with a fine-toothed hacksaw blade. This will reduce the amount of dust generated, and the edges will be as accurate as possible. The sheet initially only needs to be cut, laid on flat surface, turning the groove down. Next, the knee must be placed on a large part of the canvas, and the smaller one should be pulled towards you. In the required place, the plate will have to crack along the cut.

If during the repair work it is necessary to bypass the pipeline system, then it is necessary to apply grease to an element with the same diameter and lean it against desired area plates. This will mark the edges for cutting. It is possible to perform cutting work by means of a “crown”. If it is necessary to obtain a hole that is of considerable size and has uneven edges, it is recommended to make an incision, observing the perimeter, and then gently knock out the resulting element with a hammer.

Carrying out markup

Before laying, it is necessary to prepare sheets that will correspond to the parameters of the room. For this, the canvases are laid out, and then markings are applied to their surface so that it is possible to carry out the correct cutting. After the sheets are turned into blanks, they should be laid out again around the room and numbered - this will eliminate mistakes.

Features of laying DSP on the floor

Before laying the cement chipboard on the floor, the cement particle board must be removed from the room to make it easier to work. Its laying is carried out on glue or self-tapping screws, depending on the features. However, the drill with a nozzle must be set to low speed. It is unlikely that such a result will be achieved manually.

Ensuring clearances

DSP-slab, reviews of which, as a rule, are only positive, can be laid on the floor after the master manages to spread the glue over the surface of the rough base. This must be done with a notched trowel. When laying the following sheets, it is necessary to ensure temperature gap, which will eliminate the deformation of the canvas when changing their size. The formed gaps can be filled with the same adhesive mass. After the floor of the room is completely covered, it is necessary to leave it until it dries. Only after that you can start laying the decorative coating.

The technical characteristics of the DSP slab are such that it can replace a concrete screed. And the advantage of the canvas is that it weighs much less than the solution, while laying it is easier. In addition, the floor after completion of work acquires heat-insulating and noise-reducing properties.

The world is arranged in such a way that new materials and equipment are constantly being created, completely replacing obsolete inventions. Such parallels can be drawn to many modern building materials that are successfully replacing their old competitors.

Such innovations include DSP floor slabs, which are excellently used instead of cement-sand mortar screed as a rough floor covering, especially in wooden and frame houses.

Characteristics of the DSP, its advantages and disadvantages

Cement particle board (CSP) is a durable building floor material that has excellent thermal insulation and water repellency.

The DSP floor is characterized as a fast-installing structure, which has varieties in thickness, directly dependent on the patency in the room. This type the subfloor has its own characteristics in installation and structure, as well as certain distinctive characteristics.

Characteristics of the DSP

One of the most important indicators that characterize the DSP board for the floor is the density. For a standard cement particle board, its value reaches 1300 kg per m 2.

Also, the most important property of the material can be considered humidity, which is always in the range of 6-10% (the product passes factory tests). If the particle board has been in contact with water for a long time, its swelling percentage should not exceed 2%. Only if this requirement is met can the material be placed on the market. This property is one of the main advantages of DSP.

DSP floors can be installed in bathrooms on wooden frame or concrete base, leveling the rough surface.

Answering the question: “What is a DSP?”, we can say that this is a multi-component product. Indeed, this type of slab contains 65% cement, 25% wood chips. different breeds, 8% water or other moisturizing fluid and 2% water glass or equivalent.

DSP for the floor has standard size 3200x1250, but this does not mean that the product cannot be of other sizes (on order at the factory, cement-bonded particle board of any parameters can be made).

This type of product has differences in the thickness of the building material, which is 10, 20, 25, 30 and 40 mm, which adds versatility to the product and makes it possible to use it in a fairly wide area for both indoor and outdoor use.

Some plate parameters are given in the table.

Advantages and disadvantages of DSP

Cement particle board is definitely a high quality sheet material, which is widely used in indoor and outdoor work. DSP is very often used when organizing floor coverings and making facade cladding.

Like any other material, it has its positive and negative properties. The clear advantages of CSP include:

• good water repellency;
• ease of installation;
• relatively low cost of the material;
• good sound insulation performance (indicators reach 30dB);
• resistance to sudden changes in temperature;
• the product is not subject to rotting and fungal infections;
• high degree of fire resistance (due to special additives in the DSP);
• long service life;
• environmentally friendly material (no harmful resins);
• perfectly flat surface of the product (ready for installation of tiles or stone).

The disadvantages of a product made of cement-bonded material include, first of all, harmful installation (sawing DSP) and the weight of the plate. For more information about the types of plates and the features of their application, see this video:

It is important to remember that when cutting particle board, it is very important to observe safety precautions and resort to the use of tools personal protection especially a respirator.

Since the dust emitted during sawing of the material has harmful elements and can easily clog the respiratory tract. In addition, due to dust, the visibility of the work being done is deteriorating, so you should be extremely careful and careful to avoid injury.

Due to its excellent thermal insulation and water resistance qualities, DSP has established itself as an excellent material for rough floor construction in almost any room: on verandas, in the bathroom and in the bathroom.

The use of DSP floor slabs is strongly recommended during construction frame houses by Canadian technology. Since the plate (26-40 mm) is able to withstand a sufficiently large load, it is allowed to make floor logs not 40 cm, but 50-60 cm (under the width of the insulation).

Preparation for DSP before installation is not required (only sawing according to the right size), the slab can be laid on logs 50-80 mm wide, leaving a deformation gap of 2 mm (between the sheets).

Before attaching the DSP to subfloor, you need to see if the sheet will cover pipe hole. If the plate still covers the pipe, it is necessary to mark up 1 cm larger diameter pipes and cut the opening with a jigsaw (if large diameter), having previously drilled a hole with a 6-8 mm drill or made a cut with a hacksaw for metal, and then beat it out with a hammer (if the hole is on the edge).

Based on the characteristics of the rough floor, it is possible to “put” the DSP on the floor using an adhesive solution, additionally fixing the fastening with self-tapping screws.

Before installation, the adhesive is diluted in a certain proportion with water and mixed with a mixer to the desired consistency, after which it is evenly laid out on the floor surface (not smaller sizes sheet), only then the sheet lays down. A gap must be observed between the sheets (as with mounting on logs). When the flooring is laid, all gaps are filled with glue. For details of wall and floor finishing, see this video:

You should be aware that before installing a cement-bonded particle board on the floor, it is necessary to measure all the dimensions of the room, cut the boards and number them in the order of installation. If possible, cutouts for pipes should be made immediately.

Summing up the article, we can confidently say that DSP is a new, absolutely effective material that helps to simplify and speed up the installation of both the floor and the house as a whole without loss of quality.

Cement particle board, despite its heavy weight, has won a large army of "fan builders" who will never refuse to use this product due to the huge list of its positive advantages.

Leveling the subfloor for a decorative device finish coat can happen in more than one way. Cement screed for this case is the most time-consuming and time-consuming process. Often, sheets of chipboard are simply laid on the base. This material shows its weak sides both in the course of work with it, and in the subsequent operation. Chipboard has a fair amount of fragility, the ability to break at the ends and corners of sheets when sawing and fastening. Floors with such a base do not tolerate excess moisture therefore 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 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 it mechanical strength with chipboard, the result will be 3 times higher. DSP has a very high resistance to physical attack of any kind, immune to fungal infections and mold formation. These boards do not have the main disadvantage of chipboard - hygroscopicity. The ability to fully withstand a humid environment and critical temperatures, absolute incombustibility and reasonable 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 DSP production technology 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 internal and exterior finishes 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 the laying of DSP along the logs. In the process of working with plates, one more advantage of the product will appear: convenient installation, ease of cutting, drilling and fastening.

Preparing for DSP Coating

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

In the case of preparing the foundation for a new floor on the first floor of a private housing construction with open ground the earth surface is initially leveled. A bulk pillow is arranged on it sand and gravel mixture about 20 cm thick and compacted very well.

Supports for logs in the form of columns (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 laid out in the form of a well, reinforcing them inner part and pouring concrete. The distance between the supports can vary from 50 cm to 1 m and depends on the cross section of the beam from which the logs will be made. Then waterproofing is attached to the supports.

The concrete base is checked for deviations in the horizontal level. If the indicators do not exceed 3-4 cm, then the floor is considered suitable for further work, and eliminate minor differences by placing compensating pads under the logs. 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 lag for the floor from the DSP, it is necessary to use dry and processed antiseptic bars with a section of 100x50 mm or 150x100 mm.

All damage concrete base in the form of cracks and pits must be puttied or sealed cement mortar. Waterproofing can be done by laying a thick polyethylene film with a slight overlap from the floor to the walls.

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

• wooden beam with a section of 150x100 or 100x50 mm;
• antiseptic solution for wood;
• hacksaw with fine teeth;
• waterproofing;
• insulation;
• kapron fishing line;
• ruler, felt-tip pen;
• dowel-nails;
• self-tapping screws;
• drill;
• grinding machine;
• 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 fungus. Instead of a special tool, you can use the processing of engine oil, which has 2 advantages: low price and the absence of foreign smell. If floors from DSP are arranged on cement screed, then the cross section of the beam can be reduced to 50x50 so as not to take usable space at the premises.

It is important to follow strict horizontal level when installing lag. The first bars are mounted on two opposite walls, and a fishing line is pulled between them. Logs are stuffed with a distance of 40-50 cm, the most suitable for installing sheet chip materials. Then, with the same step, ribs for the transverse crate are attached. Fixation occurs with the help of 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 proceed to the installation of insulation. For this, it is possible to use any type of insulation: from foam and foil polypropylene to mineral wool and traffic jams.

Floors on the logs of cement-bonded particle board begin to be laid, 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 by a grinder, but with the help of a hand saw they are divided into parts quite simply. With a hacksaw blade, a furrow is drawn along the line of marking, and part of the plate easily breaks off in the right place when pressed.

The floors along the logs are laid from DSP with a mandatory run-up at the seams. The plates are attached to the wooden beam with self-tapping screws, and the gap between them is subsequently closed with putty or tile adhesive. Often, tubercles form at the joints of the plates, 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 individual sections of the floor. Upper layer it is desirable to treat with a composition with waterproofing properties, especially if the humidity in the room is above normal limits.

When arranging one of highlights can be considered a matter of choice of coverage. There is a lot of humidity in these rooms, water often appears on the floor, and this can result in blisters, 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 particle boards. What are their characteristics, what application, pros and cons of use, how suitable are they 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 (DSP)

With the current rich selection of construction and finishing materials the townsfolk sometimes run their eyes wide, and it is quite difficult to stop at one or another product. To facilitate this task, here is a list of DSP characteristics:

• the stove under warranty must serve 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 particle board can withstand exposure to a flame, preventing the fire from spreading);
• low level of moisture absorption;
• zero level of toxicity;
• ecological cleanliness;
• high reliability.

DSP has a high degree of environmental friendliness

DSP boards are intended specifically for rooms with constant humidity, the advantage of this material is that both a master specialist and a layman can work with it. The use of such a plate can both speed up and significantly reduce the cost of work on arranging a bathroom and a bathroom. 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 work with a covering, its processing;
• adequate price;
• no rotting processes even with constant contact with water;
• fire resistance due to the presence of cement in the composition of the plates.

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

• during installation, without proper dexterity, a plate of small thickness may break;
• the coating has a high density;
• the plate weighs quite a lot, so it is not suitable for facing high walls.

These disadvantages are insignificant, so this material is in high demand.

Check Quality Certificates Before Purchasing

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

1. When drilling holes, you need to indent from the edge of 2-3 cm, no less, then the plate will not crack or crumble.
2. If the plate is fixed on any surface other than wood, only metal screws should be used.
3. When working with these plates, you need to be very careful, the DSP material can be quite fragile.
4. Before final finishing plate needs to be primed.
5. If you need to cut the plates in certain fragments, then you need to use a special cutting tool with diamond coating.

Given all the above information, we can say that DSPs have occupied their niche in the construction and finishing industry. They are practically indispensable in the construction of foundations on wooden subfloors, 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 bathtub, dryer, large, other irreplaceable things in the household. They can also be used where there is a possibility of subjecting flooring significant mechanical stress. Another plus DSP are good soundproofing qualities. The aesthetic qualities of the plates are also on top, while they are undemanding in care, they are very easy to wash and clean.

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

Tools required for the installation of cement-bonded particle boards

• 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 repaired premises. Sheets need to be laid out, carefully adjusted and marked so that during fine laying do not confuse.

According to user reviews, the plates are very convenient when installing the floor, especially when you need to reduce the time of work. Many praise precisely the versatility and elasticity (the two outer layers are made from shavings minimum size, and the inner one, from a longer and larger one). Consumers also appreciate the perfectly flat surface that these plates can provide. They easily replace the usual concrete screed.

CSP is perfect for the bathroom floor

DSP selection

By purchasing plates (in fact, this also applies to all other construction and repair materials), it is necessary to 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 good system discounts for wholesale buyers, which means that you can save a lot by calculating in advance how much material you need and making a one-time order at the best price.

No hazardous additives are used in the production chemical compounds, such as formaldehyde, harmful resins, etc., so the material should not have any sharp foreign odors.

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

In any case, cement-bonded particle boards are great choice for arranging floors in the bathroom, and the information in this article will help you navigate. Watch the thematic video, and use only the best materials when repairing!
