Cement particle board is a building material that is made from chemical additives. These additives reduce the harmful effects of wood on cement, fine shavings (wood) and Portland cement.

Features of DSP finishing

DSP is used for wall cladding (both external and internal). The main competitors of CBPB are: plywood, plasterboard, OSB, chipboard. The disadvantages of CBPB is its high density - 1.4 t/m3. Also, due to its low bending strength, it can break.

Before starting to process the panel, you need to make sure that there are no chemical manifestations on its surface. If found, they should be removed with sandpaper or industrial soap.

Putty for CBPB should be limited only to the area of ​​the seams. To do this, using a spatula, put putty in the gap between the joints of the plates. (flush), and at the same time they putty the places where the screws will be installed. Putty for CBPB is made in order to provide protection against corrosion. After the putty has dried, final puttying is performed. To remove irregularities, the places where the slabs are laid are rubbed.

After the DSP joints have been sealed, the façade cladding can be subjected to further processing. To do this, preliminary priming is carried out with a primer composition. Priming is done with a brush or brush. Particularly carefully prime the cut edges of the slabs and the places that were cut out for pipes. After sealing the DSP joints, priming and other finishing work have been completed, you can begin painting and cladding. So, if you decide to tile with ceramic tiles, then DSP is exactly what you need. Because it provides a smooth surface and a very rigid structure that ceramic tiles require.
The same principle is used when processing inner surface cement particle board.

DSP - has excellent sound insulation properties. If you use mineral wool with DSP, you get very effective remedy, which can protect against noise. If we consider the DSP from the outside fire safety, then according to GOST this material is assigned to the category of low-flammability.

DSP boards do not have a negative impact on the human body, as well as on the environment. This is due to the components included in this slab. So, cement particle board can be safely used in the construction of modular houses.

Wood panels have gained wide popularity in construction. Together with undeniable advantages(ease of processing and installation, availability) wood-composite materials also have disadvantages. These include poor water resistance, deformation and delamination upon contact with moisture, as well as the content of harmful formaldehyde resins. To avoid these negative features, cement bonded particle boards were created. In the article we have already examined the main properties of this material; in this publication we will talk about the features of the operation and installation of DSP.

What do you need to know when working with DSP?

First, it is necessary to clarify some technological points. First of all, it is important to understand that this is not quite a wood-composite board in its usual sense (OSB, chipboard). The share of shavings in the structure of the material is 30 - 20%, the rest is Portland cement and chemical additives for the mineralization of the wood component, so the properties of the slab are closer to concrete products.

• Weight- cement particle boards have significant weight, so installation by one person is difficult, especially if we're talking about about wall cladding at the level of the second or third floor.
• Fragility- do not forget that cement is brittle material, so it is not recommended to throw DSP. If there is nothing on the OSB when dropped from a height, the cement board will most likely crack.
• High density- the material has high density, this gives it the opportunity to perform load-bearing functions, but at the same time cutting is difficult. Woodworking tools are not suitable for working with DSP.
• Low bending strength- the minimum bending strength established by GOSTs for the TsSP-1 brand is 12 - 9 MPa. There should not be much mechanical stress in the sheet, as this can lead to the plate breaking under its own weight.

The slabs should not be lifted by the edges parallel to the ground, this can lead to the material breaking under its own weight. It should be carried with the edge to the ground and stored in a horizontal position.

• Dusty work- when cutting with DSP, a large amount of cement dust is released, for this reason cutting in a confined space is difficult. When working, you must use .
• Thermal expansion- a property that is inherent to one degree or another in all types of wood-composite boards. In DSP, deformations caused by changes in humidity and temperature levels are minimal, but they are still present, for this reason it is necessary to make an expansion joint during installation. It is not possible to seal it with a hard material such as putty or cement, since due to deformation the cement-bonded particle board products will put pressure on the seam. As a result, cracks will appear.

Sawing

Cutting the material is an important step when working with. As mentioned above, the sheets have significant weight, so installation is usually carried out in one step. To do this, the sheets are marked on the ground in advance, numbered, holes are drilled for self-tapping screws and countersinked. We must not forget about creating holes for communications (pipes and wiring), cuts are made according to the markings, then part of the sheet is simply knocked out.

Although the material belongs to wood boards, it is difficult to use tools for woodworking. Drills and cutting elements of the saw must be made of hard alloys.

• (angle grinder or angle grinder) - hand tool for grinding and cutting various materials. For cutting DSP, we will be primarily interested in the cutting functions of the device. The main parameter is considered to be power. If we are talking about cutting several sheets for a small area of ​​flooring, then you can get by with a household grinder, but such a tool is not suitable for intensive work. For active use throughout the working day, it is better to take models with a power of 2 kW or more. When working with an angle grinder, it is important that the operator’s hands are covered with a protective cover. To make cutting in different positions easier, some models feature an adjustable handle and an adjustable guard.

When cutting hard concrete products, segmented diamond discs are used. The segments allow the working element to be cooled by air circulation.

• - for cutting cement-bonded sheets, a hand-held, table-top or stationary circular saw can be used. Using a guide allows you to get an even cut. The choice of power, as for an angle grinder, depends on the intensity of work. To cut material with a circular saw, it is better to use a diamond blade for hard materials. It is recommended to take a disk diameter of at least 250 cm. Useful feature circular saw- presence of a pipe for connection construction vacuum cleaner, this will reduce the amount of cement dust in the air.

When cutting CBPB, it is imperative to use respiratory and eye protection (,).

Fasteners

In most cases, the sheets are attached to the frame using screws or nails. Other fasteners are used for auxiliary work, for example, when installing sheathing.

• are used for attaching brackets with lathing to the main wall when installing curtain facades and partitions.

• - rod fastener, which is closed on both sides by heads, connecting two structural elements. Rivets are used to fasten the sheathing to the brackets. Installation is in progress.

• - designed for fastening insulation.

• Nails- steel rod fastenings. Screw nails are used to fix the DSP. When the slab moves, the nail will bend, but will not cut it off. This property is especially important for inclined planes. It is better to choose galvanized hardware, especially when it comes to using products in conditions of high humidity. The length of the nail should be 2.5 times greater than the thickness of the sheet. For example, it is recommended to fasten slabs 8 - 10 mm thick with nails 2.5 mm long and 35 mm in diameter; lengths 40 and 50 mm are suitable for 12 and 16 mm.

Example of using different fastening systems

• Self-tapping screws- the most common method of fastening CBPB, since the self-tapping screw acts on tearing, which is important due to the large weight of the slab. Holes for fastenings must be made in advance; it is recommended to use a screwdriver for tightening. The principle of selecting fasteners is the same as when selecting nail sizes. Before tightening the screws, the holes are countersunk to recess the head. Fasteners equipped with a countersunk head and reinforced blades for better fastening can be used without pre-drilling holes or countersinking. It is recommended to use only self-tapping screws with anodized or galvanized coating. It is better not to use phosphated products (black screws), since after finishing rust may show through the paint.

Installation of a curtain facade

One of the common methods of application is a curtain wall, which allows you to insulate, increase sound insulation, level the wall of the house and protect it from the aggressive influence of the external environment. Curtain facades are used for brick or wooden houses. It has a multilayer structure, which consists of different layers.

• - steel fasteners that serve to fix the curtain wall to the wall. These elements should be selected based on the house design; for this purpose, specimens of different lengths and thicknesses are produced. To mount the DSP, it is best to take a bracket. Another function of this element is the alignment of the façade relative to the main wall. For this purpose, special brackets with variable length and holes for fixing the moving part are designed.

Various types of brackets, the third has an adjustable length for leveling the curtain wall

• - placed between the insulation and the wall. Allows steam to freely exit the house through the wall, preventing it from condensing on the wall.
• Insulation - the layer allows the heat to remain inside the house; the insulation can be attached in one layer or in two. In the latter case, the layers should overlap each other, eliminating “cold bridges”. The insulation layer is attached using.
• layer performs a waterproofing function, allows air to escape from the house, but prevents moisture from entering the wall.
• Air gap (vent gap) serves for normal air circulation inside the wall, the presence of ventilation contributes to the evaporation of condensate. The size of the ventilation gap must be at least 20 mm from the windbreak to outside battens.
• Lathing- an element that serves to hold the DSP sheet; the lathing can be made horizontal or vertical. The material you can use is wood or steel frame. If the sheathing is attached directly to the wall without brackets, then the insulation will not fit under it - such a wall will simply be a facing wall.

Lathing options for attaching a curtain wall façade for CBPB

• Layer- sheets must be attached to each rack at at least three points. In this case, it is necessary not to forget about expansion joints, which should be 3 - 5 mm. Cement-bonded particle boards are attached to the sheathing using self-tapping screws. It is better to drill holes in the sheets on the ground in advance.

• Finishing layer- a decorative finishing layer in the form of paint or plaster, which is applied to the DSP.

To level the wall, two brackets are fixed to two anchor bolts, the level between which is measured with a rope (mooring), also suitable for this purpose. This is a measuring device that works on the principle of connected vessels.

The hydraulic level consists of two containers with scales, which are connected by a transparent tube. The containers are filled with colored liquid. To work with this measuring instrument you will need two people. It is necessary to ensure that the liquid in both containers is at the same level on the scales.

They are hung on the upper brackets to break the walls vertically. The length of all other brackets is set relative to the plumb line. When the levels are installed, the brackets are fixed in increments of no more than 600 mm.

Construction of a frame house

Technology frame houses has recently gained wide popularity. The main advantages are the speed of construction and the availability of materials. There is a place in this matter for . OSB (OSB) is considered more common in this area - oriented strand board. OSB is often cheaper in cost than cement board, but cement board is more environmentally friendly, since it does not contain harmful resins. Also, cement products have high moisture resistance, while oriented strand board begins to deform when exposed to moisture. For all these reasons, DSP can be used in frame house construction.

- This is a material made from large chips, which are arranged in layers. The elements are oriented along different axes, hence the name of these products. In each layer, the chips are directed in a certain direction, overlapping the previous one. Synthetic resins are added as a binding element.

The frame is the “skeleton” of the house; it is covered with panels that form the strength body of the building and provide thermal insulation. These panels are sometimes called “pie” because they are made up of many layers. There are a large number of panel layout variations. Sometimes the DSP is fixed on the frame itself, then there is a layer of vapor barrier, a sheathing made of timber, between which the insulation is attached. On the outside, the “pie” is completed by another outer sheet of DSP. The thickness of the sheets can vary from 10 to 16 mm. Moreover, if the house is multi-story, then block and beam structures will be required to lift the sheets to the height of the second floor. Holes for self-tapping screws are also made in advance. Fasteners are installed every 15 cm. In the central part of the sheet, fastening every 30 cm is allowed. One slab should fit three sheathing posts. Don't forget about expansion joint, which is filled with sealant to protect the heat insulator.

House frame covered with DSP sheets

Interior decoration

Inside the house it is used to create partitions, cladding walls and ceilings, and for laying subfloors.

• Subfloor- laid out for subsequent installation of the finished floor in the form of laminate or parquet. DSP finds application in different variations of this element of house construction. The most primitive option for a subfloor is laying the covering directly on the ground. In this case, you can use sheets with a thickness of 24 - 26 mm. For frame houses, the first floor is formed on top of the foundation frame; the floor consists of a system of joists on which cement-bonded particle boards are laid. To create insulation, a layer of thermal insulation, vapor barrier and wind protection is installed. A similar floor structure can be used when building a house from timber; the joist system is usually built into the frame. In fact, in this case, the DSP replaces the concrete screed.

Use case when CBPB replaces a concrete screed

If a concrete screed is present, but its evenness leaves much to be desired, a layer of cement-bonded particle boards can even out the flaws. To do this, the sheets are laid on a system of logs, the distance between which should be no more than 600 and no less than 300 mm. The thickness of the cement coating should be 20 - 26 mm. Technological clearances it is necessary to leave not only between the sheets (2 - 3 mm), but also next to the walls (10 mm). To do this, wooden choppers are installed between the wall and the outer slab.

If there is a flat concrete screed or subfloor, installation of DSP can be done using adhesive mixtures. To do this, the solution is thoroughly beaten and evenly distributed with a notched spatula. The sheets are seated on the composition, the seams are also filled with glue.

Option for installing flooring with adhesive composition

• Partitions - these are the elements that allow you to differentiate interior spaces in the house into rooms. The DSP is mounted on a rack metal carcass or a sheathing made of wooden beams. The frame is attached to supporting structures (floor, ceiling, walls) with anchor dowels (plastic or metal). If a timber frame is installed, the material must be treated with antiseptic agents. Sound insulation tape is laid at the junctions with supporting structures. To insulate the partitions, a layer of mineral wool is placed inside. Cement-bonded particle boards are attached to the frame using self-tapping screws or nails.

Structure interior partition from DSP

• Finishing facilities- products made from shavings and cement allow you to level the surface of curved walls, in this case the design resembles a curtain wall, only the work is done inside the house. The sheathing frame is constructed from wooden blocks, which are processed, or a steel profile. The profile or lathing is fixed to the wall, sound insulation and insulation, if necessary, are placed between the DSP and the wall. Also, in some cases, attachment to various adhesive solutions is allowed.

Steel lathing for subsequent fastening of CBPB

• Flat roof- This economical way coverings, it is usually used for sheds, workshops and other outbuildings and service buildings, although in modern high-tech houses a flat roof is not so uncommon. Cement slabs can be used to create roof coverings. They are secured to the beams using self-tapping screws. To avoid leaks at the seams, sheets are usually laid in two layers, while upper layer overlaps the lower one. Above roof covering For waterproofing it is covered with several layers. Ruberoid is attached to mastic. Corners are installed along the edges, which are secured with self-tapping screws and press washers.

Preparing for finishing

Often tiled houses are painted or plastered directly on top of the slabs; this type of finishing is very simple and convenient. Thanks to the even geometry of the sheets, the paint will adhere well after simple preparatory procedures. Good adhesion ensures easy adhesion of the finish coat.

• Depth of fasteners- the heads of screws and nails should not rise above the plane; for this purpose they are recessed into the material.
• Repairing chips- during construction work, defects, chips, and scratches may appear on the slabs. Before finishing, they need to be covered with putty.
• Surface defects- after installation, various color defects (efflorescence, traces of rust) may form on the surface of the slabs. These unnecessary “patterns” are cleaned off with a soap solution.
• Primer made with elastic acrylic paint, it can be done even before installation, then it will be possible to cover all the ends.

Painted frame house in fechwerk style

It is recommended to carry out painting 6 - 7 months after installation. The procedure is carried out in two stages. The first layer is preparatory - in some places it can be lighter or darker, the second layer already allows you to obtain an even coloring of the surface. It is best to use acrylic, silicate or latex paint.

Conclusion

Thus, working with DSP compared to oriented strand board has a number of nuances. The products are heavy, which requires the efforts of several people during installation. It is better to do all holes, measurements and manipulations with products on the ground. At proper preparation The surface of cement particle boards is easy to paint.

Building yard

Traditional methods of house construction and building decoration that have been used for centuries are gradually losing their relevance. Modern construction technologies are focused on new materials with high performance, structural and environmental properties.

One of these materials is CSP - cement bonded particle board. It appeared on the Russian market not so long ago, but the prospects for its use on the scale of domestic housing construction seem quite significant.

Finishing the facade with DSP boards - photo

DSP are monolithic sheet slabs with a density of up to 1400 kg/m3 and a thickness of up to 35 mm, having a very smooth top layer with a specified hardness. These products are in great demand in increasingly popular technological methods, when all wet operations are eliminated if possible and the so-called “dry type installation” is performed. The quality of these board products is regulated by GOST 26816-86, as well as by the regulatory document EN 635-2EU, adopted in the territorial space of the European Community.

DSP boards - sizes, types, characteristics

DSP is an indispensable material for the construction of new mixed-use facilities and renovation of old buildings. DSP sheets do not place load on load-bearing structures and walls. Also, particle-cement composites are used as a structural material, which is used to enhance the rigidity of elements. Without DSP applications it is impossible to carry out low-rise construction: cement-bonded particle boards are used as formwork in solid and strip foundations, thereby significantly reducing the time, labor costs and complexity of installation, since the DSP does not cause deformations during pouring, as well as during the hardening period of the concrete mixture.

Cement particle board allows you to forget about such labor-intensive operations as preparation and mixing cement mortar, plastering wall surfaces, as well as their leveling. Due to the smoothness of DSP sheets from technological process operations of preliminary puttying of the slab surface are eliminated, so they can be immediately used for priming and painting.

Production technology and component composition

What is included in the functional composite DSP:

• Portland cement grade not lower than M-500 - 65%;
• wood shavings from industrial wood waste coniferous species – 24 %;
• mineral additives in the form of aluminum sulfate or chloride – 3%;
• liquid glass – 2%;
• water – 6%.

Important! When purchasing cement-bonded particle boards for finishing the façade of an individual mansion, you should give preference to those types of cement-bonded particle boards that contain liquid glass. DSP sheets with this additive in the set of initial components are indifferent to humidity, temperature changes, and precipitation.

The production technology of this functional material is quite simple:

• a certain volume of needle crushed wood shavings is placed in the drum;
• minerals are added to it;
• Portland cement, liquid glass and water are also introduced there;
• as a result of intensive mixing, a homogeneous mass is obtained;
• the slab is formed from several floorings: in the middle of the slab there is a layer with a large fraction of chips, which determines the level of its strength. External floorings contain finely crushed shavings, which give an even surface of high smoothness;
• the workpiece is processed on a press;
• After this, the semi-finished product is transported along a conveyor belt into the hardening chamber.

The resulting products are cement-bonded particle boards of a monolithic structure that are not subject to delamination. Significant advantage received by such technologically The composite is the absolute absence of emissions of harmful volatile substances, since the boards contain no thermoplastic resins, glue or other synthetic components.

Performance properties of cement bonded particle boards

Functionality:

Strength.

The exceptional bending and tensile strength of CBPB is due to their production technology: press pressure, heat contribute to the creation of a monolith that can withstand significant loads. During deforming bending, the strength of the material changes by no more than 10%.

Machinability.

DSP sheets can be sawed, cut, drilled, sanded, milled using various tools:

• circular saw;
• Bulgarians;
• metal drill.

Angle grinders (grinders)

Moisture resistance.

The mineral components in the material, as well as the smooth surface of the board, make the CBPB practically impervious to moisture in all its forms. However, there is still a small degree of swelling: when immersed in water for a day, it swells by only 2%. That is why during the construction of buildings small gaps are provided between the slabs. A smooth surface promotes rapid evaporation of water, which is why DSP sheets are used for the construction of moisture-resistant walls, installation of hygiene and sanitary facilities in public buildings.

Environmental friendliness.

Cement particle boards are absolutely harmless to environment, they do not contain phenols, formaldehyde compounds, they do not contain carcinogenic impurities or toxic substances. Sheets of slabs do not accumulate electrical charges.

Fire resistance.

DSP is a low-flammable and low-flammable substance. Even if a fire does occur, the flame spreads very inactively, being localized at the source of the fire. When smoking, no toxic substances are released.

Resistance to low temperatures.

Frost resistance of DSP is one of the highest. Measurements showed that the destruction of the composite occurs only after fifty flexion-extension cycles. In percentage terms, this is no more than 10%, which confirms the high performance properties of the material at low temperatures. This is especially true when carrying out construction in the Arctic, Far North, Siberia and Ural regions.

Biostability.

Sheets of cement particle boards are not subject to rotting, the destructive effects of mold and fungal structures due to the antiseptic compound - calcium hydroxide. A concentrated alkaline environment of the material is formed during the production cycle, so CBPB is avoided by gnawing animals.

Harmonious union: DSP panels for exterior home decoration

Before you begin installing panels made of cement bonded particle boards, you need to decide on the thickness of the material and its dimensions. Sheet parameters according to standard:

• length from 3200 to 3600 mm;
• width – from 1200 to 1250 mm.

Material thickness in question of the device exterior finishing comes to the fore due to its significance. Here it is necessary to take into account the required wind and heat protection, the load on the slab and at the same time the load created by the material on the building frame.

• frame house construction - 14-35 mm;
• rough floors -10 mm;
• window sills, canopies, slopes - 18 mm - 30 mm;
• permanent foundation formwork - 14 mm -20 mm;
• partitions, walls - 14 - 18 mm.

On a scale frame construction walls various rooms are made mainly from slabs with a cross-sectional size from 12 to 40 mm, and on the outside they take a sheet thickness from 16 to 24-28 mm. To install a DSP on the facade of a house, it is better to take a sheet of 16, or at most 18 mm: it does not break under acceptable impact and does not create an excessive load on the frame base of the building.

Installation of DSP panels on the facade of a house

Before you begin installing panels on a frame house, you need to think about insulation buildings. As a rule, in the climatic conditions of the Russian Federation, during the installation of DSP panels on the facade of a house, insulation is used in accordance with the climatic conditions of the area where the house is being built.

Choice of insulation

The most suitable heat shields are used as different kinds insulation material:

Each type of insulation has its own positive sides and some disadvantages. Compared to insulating materials of natural origin, for example, flax production waste, their advantages are obvious: they are more effective in retaining heat inside the building.

Important! If you have chosen non-flammable mineral wool as insulation, then it is better to purchase wool in slabs rather than in rolls: it does not cake when placed vertically.

So, the insulation has been purchased, now it’s time to start installing the DSP panels. Doing it yourself is not at all difficult if you follow the instructions and meticulously follow all the instructions.

Prices for various types of insulation

Various types of insulation

Step-by-step instructions for installing DSP panels on the façade of an individual house

Step 1. We form the sheathing along the entire outer wall space.

Mount on all walls using a level reliable system fastenings in a vertical direction, capable of withstanding the serious load that will be created by the CBPB slabs. Elements of the lathing system can be wooden, for example, from timber measuring 50x50, or metal in the form of pipes rectangular section 50x20 or metal profiles. The distance between adjacent elements is at least 60 cm. The vertical direction must be maintained flawlessly, then installation of the DSP panels can be carried out without problems.

Step 2. Laying insulation.

Important! Calculation of the required volume of purchase of this façade component must be made separately, depending on the area of ​​the walls and the type of thermal insulation.

We distribute the insulation over the entire wall space, laying it between the verticals of the sheathing. The insulation must be attached to the wall with self-tapping screws of the required length.

Step 3. Adding a windproof membrane.

As soon as the building is insulated, a windproof membrane comes into play, which is applied over the insulation to the entire wall space. It also needs to be securely fixed in place. During this stage of work, you need to pay attention to the fact that the difference between the plane of the membrane and the plane of the already installed insulation should be at least 2 cm.

Prices for windproof membranes

Windproof membrane

Important! The ventilation gap must not be neglected! If you do not leave it, then there is a high probability that condensation will accumulate inside, which will ultimately lead to rotting of the frame.

Step 4. We drill holes for fasteners in the sheathing.

We prepare holes for fasteners.

Step 5. Installation of panels made of cement bonded particle boards.

Let's start installing the DSP panels. The step between fasteners should not be less than 30 cm and more than 60 cm, and the gap between adjacent plates should not be more than 5 mm. A gap is left in case of deformations that occur during temperature changes or during movements of soil layers.

In order to avoid cracking of the DSP sheets from the fasteners, the screws must be tightened at a distance of 1 cm from the edge of the slab. The same principle is used to cover decorative columns, load-bearing supports and crossbars.

Important! It is not recommended to install cement building slabs in a row along the entire perimeter of the building. Installation of the panels must be done in stages, separately on each wall. Only after the installation of cement-bonded particle boards on one wall space has been completed can you proceed to the next wall.

Step 6. Grouting joints between slabs.

After the building shrinks, the seams between the sheets of cement-bonded particle boards can be rubbed with any means intended for this purpose or decorated as appearance accents.

Step 7 Final decorative finishing walls

After the installation work is completed, you need to start decorating the walls. In this matter, each owner is guided only by his own aesthetic preferences, because cement-bonded particle boards provide an incredible variety of choices. Houses lined with DSP panels can be painted, treated with tinting compounds, and finished facade plaster or add artificial stone to the facade. Or maybe it’s worth designing the architectural appearance of the new building in the Russian style? Then you need to stick unique ones on the walls of the house design elements, imitating wooden carvings - blind, through, overhead.

Thanks to its use in construction work modern materials, in particular, cement particle boards, the house will be warm, durable, fire-resistant, and have excellent soundproofing properties. And it's also very beautiful! Finishing individual households with cement particle boards allows you to create your own unique architectural appearance of any home, any village, any city!

NOTE

When conducting finishing works, the instructions for use of the material systems given by the manufacturer must be strictly followed. The least demanding on the quality of the finished surface are texture paints, therefore they are recommended for painting facades independently with a roller. Non-textured (smooth) paints are recommended to be applied only to specially prepared surfaces with recessed and puttied screws.

To fasten TAMAK DSP to frames on facades, it is recommended to use galvanized or anodized self-tapping screws (hereinafter referred to as self-tapping screws), since black (phosphated) can corrode under the influence of atmospheric moisture; in this case, they lose their strength qualities, and rust can appear through the finish coating.

PREPARATION OF THE SURFACE OF TAMAK CBPB FOR CARRYING OUT FACADE FINISHING WORKS

Before painting, it is necessary to prepare the surface of the DSP as follows:

• deepen all screws by 1-2 mm;
• fill all recesses and chips with façade putty, for example, produced by the Leningrad NPP company “Putty for painting” + cement M500D0;
• after the putty has dried, smooth out the resulting roughness with sandpaper;
• clean the surface of the stove from dust with a damp cloth;
• To level out the absorbency of the surface of the DSP, apply a primer with a roller or brush deep penetration on all sides of the slab, including the edges;
• It is more convenient to treat the edges of the slab with a primer not one sheet at a time, but at the moment when the slabs are in a stack;
• then apply finishing materials according to the instructions given by the manufacturer.

WALLPAPER

Direct wallpapering of the working surface is carried out after attaching the primed slabs and filling the expansion joints with elastic mastic.

Surface finishing of slabs can be done using vinyl wallpaper, glass wallpaper, non-woven wallpaper. IN in this case the expansion seams will be hidden.

Vinyl wallpaper is used for finishing rooms with increased aesthetic requirements and where high wear resistance or washing ability of interior elements is required.

Attention!

1. It is not recommended to use paper-based wallpaper!
2. It is recommended to use wallpaper manufacturer's adhesive and technology.
3. It is possible to attach gypsum plasterboard sheets directly to DSP sheathings using screws with overlapping seams; in this case, it is possible to use any type of wallpaper.

COVERING WITH CERAMIC TILES

To obtain a durable finish on DSP sheathing, it is necessary to fasten the gypsum board sheets directly onto the DSP sheathing using screws with a seam overlap of at least 200 mm. (in this case, the DSP cladding plays the role of a load-bearing element).

Adhesive mastic is applied to the entire working surface of the slab. 4 - GKLV sheets.

In rooms with high humidity (bathrooms, showers), ceramic cladding of high humidity rooms is recommended according to the following scheme (Fig. 3).

FLOOR COVERINGS

Floors made of cement particle boards under thin-layer floor coverings (Fig. 5) linoleum, carpeting must be puttied over the entire plane, paying particular attention to Special attention slab joints. For putty, it is recommended to use acrylic-based elastic mastics. It is recommended to remove possible unevenness and inconsistencies between the edges of the slabs by grinding using the previously described technology

Cement particle boards (CPB) are classified as universal sheet building materials. The raw materials for cement particle boards (CPB) are Portland cement, crushed wood shavings and additives that reduce the influence of substances contained in wood on the formation of cement stone.

Manufacturing technology of cement bonded particle boards (CPB)

The technology for manufacturing CBPB can be briefly described as the formation of a three-layer “pie” from two types of cement-bonded particle mixture: a mixture with fine-bonded aggregate forms the outer layers, and with coarse aggregate - inner layer. The laminated board is then molded under high pressure hydraulic presses and obtains ideal smoothness and thickness.

Application of cement bonded particle boards (CSP)

DSP is used:

• As cladding and cladding along guides or frames, vertical - for walls, partitions, racks, ventilation casings, etc., both for interior decoration and for facades.
• As an outer screen layer of a ventilated façade.
• In floor and flat roof structures.

DSP is not a serious competitor to fibreboards, plasterboard, gypsum fiberboard and bakelized plywood, due to the variation in the characteristics of these sheet materials. All these plates are in demand depending on the working conditions and the required performance qualities.

DSP board size

The standard sizes of DSP are 2.7 * 1.25 m and 3.2 * 1.25 m with gradations of thickness in mm 8; 10; 12; 16; 20; 24 and 36.

Main technical characteristics of cement-bonded particle boards (CSP)

Let us list the main characteristics of CBPB boards:

1. Specific gravity (density) – 1250-1400 kg/m3. A standard DSP sheet with dimensions of 2.7 * 1.25 m and a thickness of 16 mm weighs 72.9 kg.
2. Ultimate bending strength for thicknesses of 10, 12, 16 mm - 12 MPa; with a thickness of 36 mm - 9 MPa.
3. Tensile strength perpendicular to the plane of the slabs is not less than 0.4 MPa.
4. Modulus of elasticity in bending – not less than 3500 MPa.
5. Classification by flammability - group G1 (classified as low-flammable).
6. Frost resistance of 50 cycles with a guarantee of a decrease in strength by no more than 10%.
7. Thermal protection properties. Thermal conductivity coefficient is 0.26 W/m*deg C.
8. The value of the coefficient of linear expansion is 0.0235 mm/m*deg C.
9. Vapor permeability coefficient 0.03 mg/m*h*Pa.
10. Specific resistance when pulling out screws is from 4 to 7 N/m.
11. Based on biostability, they are classified as class 4 products
12. For sound insulation - with a thickness of 12 mm, the value of the insulation index airborne noise 31 dB. When laid on a reinforced concrete base made of load-bearing slabs, the penetration of impact noise with a thickness of 20 mm CBPB reduces by 16 dB. When laid on elastic materials - by 9 dB.
13. Linear increases in size after exposure to water for 24 hours are 2% in thickness and 0.3% in length.
14. Service life when used in dry rooms is at least 50 years.

Pros and cons of cement-bonded particle boards (CSB)

Let us list the main advantages of CBPB boards:

• Environmental friendliness. DSP does not contain any harmful or dangerous substances either in its composition or in its manufacturing technology. There are no phenolic-formaldehyde resins in the particle filler.
• Frost resistance is good - at least 50 cycles.
• Fire resistance G1 is a definite plus for facing material.
• Moisture resistance of CBPB boards that do not have a protective layer of hydrophobization is weak, protection from moisture is required - minus
• Sound insulation and noise protection qualities are excellent.
• Good biostability. Fungus and mold do not form on the surface of the slabs, even when used in a humid environment.
• Excellent resistance to longitudinal deformations, used for cladding along guides in frame houses any number of floors.
• It goes well with other materials and structures, such as wood, polymers and plastics, metals and ceramics.
• High technology, simplicity and speed of processing. Cutting and drilling possible. Installation is simple, most hardware is suitable.
• Almost all types of finishing using DSP are possible, you can paste over any types of wallpaper, including heavy ones, plaster, tile, paint with any compositions - water-based, acrylic, oil, alkyd, etc.
• Smooth working surface DSP and perfectly even thickness allow you to save on finishing. On the smooth (cemented) side of the DSP sheet it is possible to apply a layer of paint without priming, especially since the adhesion is excellent.
• In terms of cost, CBPB boards are quite competitive with other sheet cladding materials, with favorable strength indicators.

The disadvantages of DSP boards include:

• The sheets have a significant mass, up to 200 kg depending on the thickness. When working on the upper tiers you cannot do without lifting mechanisms, which gives a certain increase in price. Installing heavy slabs at height is also difficult.
• The service life is not very long - in contact with external environment no more than 15 years. Manufacturers guarantee fifty years of operation only under normal humidity conditions, which is not always realistic.
• Thin, from 8 to 36 mm, DSP sheets with a significant area - about 4 m2 and weight cannot but have some fragility. Working with DSP is not so easy; it requires care. The slabs may break during installation.
• Sealing joints and seams between DSP sheets is not possible with any material. They recommend sealants that can mask the seam, provided they are elastic in the presence of moisture. Putty compounds that have properties of rigidity after setting cannot be used for sealing joints; this can lead to deformation of slabs operating in weather conditions and to a reduction in their service life. Sealants based on rubber bases are considered the best option for CBPB.
• DSPs are hygroscopic, and linear expansion when cladding facades is inevitable. Plaster of a façade on a DSP without a reinforcing mesh and protection of the DSP from moisture rarely does not crack after five or even less years of operation. If there are errors in installation - insufficient fasteners or frames and work in humid conditions, the DSP sheets can go in “waves” and even come off the fasteners. Sometimes experts recommend protecting the CBPB from external moisture under the plaster with damper layers of polyurethane foam, fastened with clamping rondoles (or other types of disc fasteners). This option requires elaboration regarding the fulfillment of the vapor permeability conditions for external walls. The dew point should not be allowed to winter time fell on the inner plane of the DSP.

Transportation and storage of CBPB

It is necessary to provide protection from atmospheric influences; long-term storage is possible exclusively in horizontal laying, but the CBPB is transported in the “edge” position.

Installation and surface finishing with cement-bonded particle boards (CSP)

Installation and surface finishing DSP slabs carried out in the following order:

• Before fastening the CBPB sheet with self-tapping screws to the frame or base, it is necessary to drill holes for the self-tapping screws, and the CBPB sheet must have a solid support along the plane (it is impossible to drill the CBPB “in weight”).
• Vertical cladding and cladding are usually made with slabs 16 mm and 20 mm thick.
• The most economical and fastest type of final finishing on DSP is painting with compositions based on acrylic, latex or silicone. Compensation gaps at sheet joints are required.
• DSP sheets are characterized by very smooth surface, there is no porosity. Priming on the cemented sides of the sheets need not be done, provided the CBPB is not operating in a humid environment.
• Sealing of seams and joints of DSP is possible with sealants that mask the seams, and wooden, plastic or metal strips are used for finishing. This finishing is used to imitate facades in half-timbered styles, and in particular due to the excellent smoothness and geometry obtained when cladding with DSP, the appearance is simply ideal. The “picture” of the half-timbered structure is quite realistic and has its own charm.

For leveling for final finishing, DSP sheets are considered one of the best materials due to their good rigidity and ideal smoothness of the sheets. Finishing and leveling with DSP boards gives excellent results. Finishing materials can be paint and varnish mixtures, plaster mixtures, facing tiles, wallpaper of any type, natural and artificial linoleums, laminates, cork, soft materials such as carpet and others.
