Cement-chipsticks (CSP) refer to universal sheet building materials. Raw materials for cement-chipboard (CSP) - Portland cement, crushed wood chips and additives, which reduce the influence of substances contained in wood, on the formation of cement stone.

Cement-chipboard manufacturing technology (CSP)

The manufacturing technology of the CSP can be briefly described as the formation of a three-layer "cake" of two types of cement-chip mixture: a mixture with a fine-chip filler forms an external layers, and with a large inner layer. Then the puff slab is molded under high pressure Hydraulic presses and gets perfect smoothness and thickness.

Application of cement-chipboard (CSP)

CSP applies:

• Like a covering and facing on guides or frame, vertical - for walls, partitions, racks, ventilation casing, etc. Next, both for indoor finishing and facades.
• As the outer screen layer of the ventilated facade.
• In the structures of floors and flat roofs.

CSP does not constitute a serious competition of fibreboard, plasterboard, GVL and backelovated plywood, due to variations of the characteristics of these sheet materials. All these plates are in demand depending on the working conditions and the required operational qualities.

Size of the Plate of CSP

Standard sizes of CSP 2.7 * 1.25 m and 3.2 * 1.25 m under gradations of thicknesses in mm 8; 10; 12; sixteen; twenty; 24 and 36.

The main technical characteristics of cement-chipboard (CSP)

We list the main characteristics of CSP plates:

1. Specific weight (density) - 1250-1400 kg / m3. Standard CSP sheet with dimensions 2.7 * 1.25 m and a thickness of 16 mm weighs 72.9 kg.
2. Tensile strength with thicknesses 10, 12, 16 mm - 12 MPa; With a thickness of 36 mm - 9 MPa.
3. Tensile strength on perpendicular to plane planes of at least 0.4 MPa.
4. The modulus of elasticity at bending is at least 3500 MPa.
5. Classification for combustible - group G1 (refer to weakly).
6. Frost resistance of 50 cycles when the reduction of strength is not more than 10%.
7. Heat shield properties. The coefficient of thermal conductivity of 0.26 W / m * hail S.
8. The value of the linear expansion coefficient is 0.0235 mm / m * hail S.
9. Parry permeability coefficient 0.03 mg / m * h * PA.
10. Specific resistance when pulling screws from 4 to 7 n / m.
11. Biooscope is classified as 4 class products
12. Soundproofing - with a thickness of 12 mm, the value of an index isolation of air noise of 31 dB. When laying on a w / b base carrier plates It is possible to reduce the penetration of shock noise at the thickness of the CSP 20 mm - by 16 dB. When laying on elastic materials - by 9 dB.
13. Linear zoom in size after exposure in water during the day - 2% in thickness and 0.3% in length.
14. Service life when applied in dry rooms at least 50 years.

Pros and cons of cement-chipsticks (CSP)

We list the main advantages of CSP plates:

• Ecology. CSP does not contain any in the composition, nor in the technology of manufacturing harmful and hazardous substances. Penal-formaldehyde resins in the chip filler are missing.
• Frost resistance is good - at least 50 cycles.
• Fire resistance G1 is a certain plus for facing material.
• Moisture resistance of CSP plates that do not have a protective hydrophobization layer - weak, the protection against moisture is required - minus
• Sound insulation and sound quality qualities are excellent.
• Good biostost. On the surface of the slabs does not form fungus and mold even during operation in a humid environment.
• Excellent resistance to longitudinal deformations is used for cladding on guides in frame houses of any floor.
• Perfectly combined with other materials and structures, such as wood, polymers and plastics, metals and ceramics.
• High manufacturability, simplicity and processing speed. Possible cutting, drilling. Installation is easy, most of the hardware are suitable.
• Virtually all kinds are possible finish finish According to CSP, you can have any kind of wallpaper, including heavy, plastering, tinted with tiles, painting by any compositions - water-emulsion, acrylic, oil, alkyd, etc.
• The smooth working surface of the CSP and the perfectly smooth thickness allow you to save on trim. On a smooth (cemented) side of the TSP leaf, it is possible to apply a colorful layer without priming, especially since the adhesion is excellent.
• Price plates of CSP It is quite maintained competition with other sheet facing materials, with advantageous strength indicators.

The disadvantages of CSP plates will take:

• Sheets have a significant mass, up to 200 kg depending on the thickness. When working on top tiers, do not do without lifting mechanisms, which gives a certain rise in price. Installation of heavy slabs at height is also difficult.
• The service life is not very large - under contact with the external environment for no more than 15 years. Manufacturers guarantee fifty years of work only provided normal humiditythat is not always real.
• Thin, from 8 to 36 mm CSP sheets at a large area - about 4m2 and weight cannot not have some fragility. Working with CSP is not so simple, carefulness is required. Plates can break when mounting.
• Sealing joints and seams between the CSP sheets is possible not by any material. Recommended sealants that can disguise the seams, subject to their elasticity in the presence of moisture. Putty compounds that have stiffness properties after setting, for seams of seams cannot be used, this can lead to slab deformations operating under conditions of atmospheric influences and to reduce their service life. Sealants on rubber bases are considered to be the best option for the CSP.
• CSP is hygroscopic, and the linear expansion when facing facades is inevitable. The plaster of the facade according to the CSP without a reinforcing grid and the protection of the CSP from moisture is rarely not cracking after five, or even less years of operation. In case of errors in the installation - insufficient fasteners or framework and work in conditions of humidity, the CSP sheets can go "waves" and even tear away from fasteners. Sometimes experts recommend protecting the CSP from the outer moisture by damping layers from polyurethane foam, with fasteners on clamping rondlines (or other types of plate fasteners). This option requires working as part of the implementation of the condition of vapor permeability for the outer walls. It is impossible to allow the dew point in winter to fall on the inner plane of the CSP.

Transportation and storage of CSP

It is required to protect against atmospheric influences, it is possible for long-term storage exclusively in horizontal laying, but the CSP transport is transported in the position "on the edge".

Installation and finishing of the surface by cement-chipstones (CSP)

Installation and finishing of the surface by CSP plates are carried out in the following order:

• Before fastening the CSP sheet with self-draws to a frame or base, it is necessary to sew holes for the self-tapping screw, while the CSP sheet should have a solid support on the plane (drilling the CSP "on the weight" cannot be drilled).
• Vertical trim and facing do, as a rule, with a thickness of 16 mm thick and 20 mm.
• The most economical and fast view of the final finishes on the CSP - staining with the compositions based on acrylic, latex or silicone. Compensation gaps in sheets of sheets are required.
• CSP sheets are characterized by a very smooth surface, the porosity is absent. Priming on cemented parties of sheets can not be done, subject to the work of the CSP not in a humid environment.
• The sealing of the seams and the joints of the CSP is possible by sealants masking seams, and for the finishing finish, wooden, plastic or metal strips are used. This finish is applied with the imitation of facades in the styles of the Facrow, and in particular due to the excellent smoothness and geometry obtained by the cladding of the CSP, appearance Just perfect. "Picture" of the half-timber is quite realistic and has its own charm.

For alignment under the final finish, the CSP sheets are considered one of the best materials, due to the good stiffness and the perfect smoothness of the sheets. Finishing and alignment with CSP plates give an excellent result. Finishing materials may be paint and varnish, plastering mixes, facing tiles, wallpaper of any types, natural and artificial linoleums, laminates, cork, soft materials Type carpet and others.

Wood plates have gained wide popularity in construction. Together with indisputable advantages (simplicity of processing and installation, accessibility), wood-composite materials possess the disadvantages. These include poor water resistance, deformation and separation when contact with moisture, as well as the content of harmful formaldehyde resins. To avoid these negative traits, cement-chipboard were created. In the article, we have already reviewed the basic properties of this material, in this publication we will talk about the features of the work and installation of the CSP.

What do you need to know when working with CSP?

First you need to clarify some technological moments. First of all, it is important to understand that it is not a completely wood-composite slab in its usual understanding (OSB, chipboard). The share of chips in the structure of the material is 30 - 20%, everything else is portland cement and chemical additives for the mineralization of the wood component, therefore the stove is closer to concrete products in its properties.

• Weight - Cement-chip plates have a significant weight, so the installation of one person is difficult, especially if it comes to lining of walls at the level of the second or third floor.
• Fragility - Do not forget that cement is a fragile material, so the CSP is not recommended to throw. If OSB is nothing when falling from height, then the cement plate is most likely split.
• High density - The material has a high density, it gives him the opportunity to carry out supporting functions, but the cutting is difficult. Tools for work on wood when working with CSP will not fit.
• Low bend strength- The minimum bending strength, installed by gostamas for the TSP-1 brand, is 12 to 9 MPa. The sheet should not exist a large mechanical stress, as this may lead to the fact that the stove will break under their own weight.

Plates should not be lifted beyond the edges parallel to the ground, it can lead to a bevel material under its own weight. Carrying must be carried out by an edge to the ground, and stored in a horizontal position.

• Dusty work- When cutting with CSP, a large number of cement dust is distinguished, for this reason, the cutting in the closed room is difficult. When working must be used.
• Heat expansion - a property that in one degree or another is inherent in all varieties of wood composite plates. The DSP deformation caused by changes in the level of humidity and temperature is minimal, but they are still present, for this reason, when installing, it is necessary to make a deformation seam. To close it with a solid material, such as putty or cement, it is impossible, since, due to deformations, cement-chips will put pressure on the seam. As a result, cracks will appear.

Sawing

The cutting of the material is an important stage when working with. As mentioned above, the sheets have a significant weight, so the installation is usually carried out in one app. For this, the sheets are placed in advance on earth, number, drill holes under the self-tapping screw and they are annoying them. We must not forget about the creation of holes for communication (pipes and wiring), cuts are made on the markup, then the part of the sheet is simply knocked out.

Although the material refers to wood slabsBut the use of tools for wood work is difficult. Drills and cutting elements of saws should be made of solid alloys.

• (USM or angular grinding) - hand tool for grinding and cutting different materials. For the cutting of the CSP, we will first of all be interested in the cutting functions of the device. The main parameter is the power. If we are talking about the cutting of several sheets for small plot Floor, then you can do and household bulgaria, but this tool is not suitable for intensive work. For active operation throughout the day, it is better to take a power model from 2 kW. When working with a grinder, it is important that the operator's hands are closed with a protective casing. To simplify the cut in different positions on some models there is a stopper handle and adjustable casing.

When cutting hard concrete products Segment diamond discs are used. Segments allow the work element to be cooled due to air circulation.

• - For the cutting of cement-pall sheets, manual, desktop or stationary circular saw can be used. The use of the guide allows you to get smooth cut. The choice of power, as well as for the grinder, depends on the intensity of work. For cutting material with a disk saw better use diamond Disc For solid materials. The diameter of the disk is recommended to take at least 250 cm. Useful feature Circular saw - the presence of a nozzle for connecting the construction vacuum cleaner, this will reduce the number of cement dust in the air.

With the cutting of the CSP, it is necessary to use the means of protecting the respiratory and eyes (,).

Fasteners

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

• It is used to attach brackets with a crate to the main wall when mounting mounted facades and partitions.

• - The rod fastener, which is closed on both sides by connecting two design elements. Rivets are used to fasten the crate on the brackets. Installation is made.

• - Designed for fastening the insulation.

• Nails - Steel rod fasteners. For fixing the CSP, screw nails are used. When shifting the plate, the nail brightens, but it will not cut it. Especially this property is relevant for inclined planes. It is better to choose galvanized hardware, especially if we are talking about the use of products in conditions high humidity. The length of the nail must be 2.5 times longer than the thickness of the sheet. For example, nails 2.5 mm long 35 mm in diameter It is recommended to mount the plates with a thickness of 8 - 10 mm, length 40 and 50 mm are suitable for 12 and 16 mm.

Example of use various systems fasteners

• Selfless - The most common method of fixing the CSP, as the self-tapping screw is acting on the separation, which is relevant due to the large weight of the slab. Holes under fastenings need to be done in advance, to twist it is recommended to use a screwdriver. The principle of selection of fixtures is the same as during the selection of sizes of nails. Before spinning the screws, the holes are cencing to drown a hat. Fasteners equipped with a secret head and fortified blades for better fixing can be used without pre-drill holes and cencing. It is recommended to use only self-tapping screws with anodized or galvanized coating. Phosphatated products (black screws) are better not to use, since after the finish finish, the rust can stick through the paint.

Installation of mounted facade

One of the common uses - hinged facadewhich allows you to warm up, increase the sound insulation, align the wall at home and protect it from the aggressive exposure to the external environment. Hinged facades are used for brick or wooden houses. It has a multi-layer structure that consists of different layers.

• - Steel fasteners that serve to fix the mounted facade on the wall. Select these elements should be based on the house project, the specimens are released. different lengths and thickness. For the attachment of the CSP, it is best to take the bracket. Another feature of this element is the alignment of the facade relative to the main wall. For this purpose, special brackets with changing long and holes for fixing the movable part are designed.

Different types of brackets, the third has an adjustable length for aligning the mounted facade

• - stacked between the insulation and the wall. Gives a couple to freely leave the house through the wall, not allowing it to condense on the wall.
• Insulation -the layer allows heat to stay inside the house, the insulation can be attached to one layer or two. In the latter case, the layers must overlap each other, eliminating the "cold bridges". The layer of insulation is attached with.
• layer Performs a waterproof function, gives air to leave the house, but does not give moisture to fall on the wall.
• Air gap (Ventzor) It serves to normal circulation of air inside the wall, the presence of ventilation contributes to the evaporation of condensate. The amount of the ventzor should be at least 20 mm from windproofs to outside Chatters.
• Okeekhet - An element that serves to hold a CSP leaf, a crate can be made horizontal or vertical. Wooden or steel frame can be used as a material. If the cutture is attached directly to the wall without brackets, then the insulation is not placed under it - such a wall will be simply facing.

Options for fastening the mounted facade for CSP

• Layer - To each rack, sheets must be attached at least than three points. At the same time, it is necessary not to forget about the deformation seams that should be 3 - 5 mm. To the crate cement-chipboard fasten with the help of self-tapping screws. Holes in sheets better drill in advance on earth.

• Finishing layer- Decorative finishing layer in the form of paint or plaster, which are superimposed on the CSP.

For alignment of the wall on two anchor bolts, two brackets are fixed, the level between which is measured by the rope (mooring), and is also suitable for this purpose. This is a measuring device based on the principle of connected vessels.

The hydroelector is two containers with scales that are interconnected by a transparent tube. Capacities are filled with tinted liquid. To work with this measuring instrument It will take two people. It is necessary to ensure that the liquid in both capacitations on the scales is on the same level.

On the upper brackets hang for twisting vertical walls. Regarding the rope of the plumb, the length of all other brackets is set. When the levels are installed brackets are fixed with no more than 600 mm increments.

Construction of a frame house

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

- This is a material made of large shavings, which is located in layers. Elements are focused on different axes, hence the name of these products. In each layer, the chips are directed in a certain side, overlapping the previous one. Synthetic resins are added as a binding element.

The frame is a "skeleton" of the house, it is trimmed with panels that form the power body of the structure and provide thermal insulation. Such panels are sometimes called "pie", since they consist of a variety of layers. There is a large number of variations of layout panels. Sometimes the CSP is fixed on the frame itself, then goes a layer of vapor barrier, the lamp from the bar, between which the insulation is attached. Outside, "Pie" completes another external sheet of CSP. The thickness of the sheets can vary from 10 to 16 mm. At the same time, if the house is a multi-storey, then for lifting sheets to the height of the second floor, block and beam structures will be required. Holes for self-tapping screws are also made in advance. The fasteners are installed through each 15 cm. In the central part of the sheet, the mount is allowed after 30 cm. One plate should have to be three racks of the crate. Do not forget about the deformation seam, which is filled with sealant to protect the thermal insulator.

Frames at home, covered with CSP sheets

Interior decoration

Inside the house is used to create partitions, wall cladding and ceilings, for styling the draft floor.

• Chernovaya Pol - laid out for the subsequent installation of the first floor in the form of a laminate or parquet. CSPs finds itself use in different variations of this element of the construction of the house. The most primitive version of the draft floor is the laying of the coating directly to the ground. In this case, it is possible to use sheets with a thickness of 24 - 26 mm. For frame houses, the first overlap is formed on top of the cloves of the foundation, the overlap consists of the lag system, which is stacked by cement-chip products. To create insulation, a layer of thermal insulation, vaporizolation and windscreens are installed. A similar floor structure can be used in the construction of a house from a bar, the lag system is usually embedded in a bustling crown. In fact, in this case, the CSP replaces the concrete screed.

Use option when CSP replaces a concrete screed

If the concrete screed is present, but its evenness leaves much to be desired, the layer of cement-chipboard can align flaws. For this, the sheets are placed on the lag system, the distance between which should be no more than 600 and at least 300 mm. The thickness of the cement coating should be 20 - 26 mm. Technological gaps should be left not only between sheets (2 - 3 mm), but also next to the walls (10 mm). For this, wooden choppers are installed between the wall and the extreme slab.

In the presence of a flat concrete screed or black floor, the installation of the CSP can be produced on adhesive mixes. For this, the solution is thoroughly whipped, evenly distributed to the toothed spatula. Sheets are seated on the composition, the seams are also filled with glue.

Installation option outdoor coating on glue composition

• Partitions -these are elements that allow you to delimit interior In the house on the room. CSP is attached to a rack metal frame or a crate from wooden bar. The frame is attached to the carrying structures (to the floor, ceiling, walls) anchor dowels (plastic or metal). If the frame is installed from the bar, the material must be processed antiseptic means. In places of compounds with supporting structures, a tape is laid for sound insulation. For insulation of partitions inside the layer mineral wool. Cement-chip plates are attached to the frame using self-tapping screws or nails.

Structure interior partition from CSP

• Finishing facilities - Products made of chips and cement make it possible to level the surface of the curves of the walls, in this case the design resembles the mounted facade only work is made inside the house. The frame of the crates is constructed from wooden bars, which are processed, or a steel profile. A profile or lamp is fixed on the wall, a sound insulation and insulation is placed between the DSP and the wall, if necessary. Also in some cases is allowed to mount on various adhesive solutions.

Steel case for subsequent fastening of CSP

• Flat roof - this is an economical way of covering, usually it is used, for sheds, workshops and other economic and service buildings, although in modern houses High-Tech style flat roof - Not so much and rarity. Cement plates can be used to create roofing. In the beams, they are fixed using selflessness. To avoid leaks in the seams, sheets are usually put in two layers, while upper layer Overlaps the bottom. From above, roofing coating for waterproofing is covered with several layers. Ruberoid is attached to mastic. Along the edges install corners that are fixed with self-presss with pressshabs.

Preparation for finishing

Often at home, lined, paint or plastered right on top of the plates, this type of finishing finish is very simple and convenient. Due to the smooth geometry of the sheets, the paint will be good to lie down after conducting simple preparatory procedures. Good adhesion provides a simple adhesion of the finish coating.

• Blowing fasteners - Hats of self-tapping and nails do not have to rise above the plane, for this they are interinted in the material.
• Sealing chip - In the course construction work Defects, chips, scratches may appear on the plates. Before the beginning finish treatment They need to smear with putty.
• Defects on the surface - After mounting on the surface of the plates, various color defects may form (zip, rust trails). These unnecessary "patterns" are scheduling with a soap solution.
• Primer It is made by elastic acrylic paint, it can be carried out before installation, then all the ends can be sampling.

Painted frame house in the style of Fehrom

Coloring is recommended after 6 - 7 months after installation. The procedure is performed in two stages. The first layer is preparatory - in some places it can be lighter or dark, the second layer already allows you to get smooth surface color. It is best to use acrylic, silicate or latex paint.

Output

Thus, working with CSP compared to the oriented chipboard has a number of nuances. Products have a lot of weight, which requires efforts of several people when installing. All holes, measurements and manipulations with products it is better to do on Earth. For proper preparation The surface of cement-chipboard is easy to color.

Building yard

In the first part of the article we talked about the advantages of cement-chipboard, the facade of the CSP and the correct installation of this material on external walls. In this material we will answer the following questions:

• How to decoratively separate the facade from CSP paint and plaster.
• How to beautifully close the joints of the slab styles.
• How to make a facade under Siding.

What and how to separate the facade from the CSP

Jenialu. User forumhouse.

I have experience with CSP on the facade. The paint is a normal solution, but, due to the thin layer, it poorly covers the jokes of the plates and the fastener location. I tried to glue clinker tiles on cement-chipboard. Result - 120 square meters fell from the facade. m.

CSP has a smooth surface, so the classical methods for finishing the plates on the facade do not work.

So, the developer stands before choosing how to proper the CSP. The most important is the preparation of seams, because In the case of hack, all shoals will then be shown on the facade. In the first article we already wrote that between the plates, it is necessary to leave a deformation gapabout 6-8 mm. Now the question arises: make seam open or closed? Overlooked seam, in most cases, is not suitable for aesthetic considerations. In addition, you need to protect wooden barber (Vertical racks of the root), on which the stove is attached, waterproofing material.

If this is not done, then the open rain and the snow bar will begin to rot.

Another option is to close the seam with a decorative plank - asset. This option is most often used if the facade from the CSP is stylmed by falsefield.

Important:decorative planks can be selected from wood, CSPs with a thickness of about 16 mm or fibro-cement siding with a texture under a tree. For example, did the participant of the portal with nickname Sergeyu,stopping layouts with a length of 3600 mm and a cross section of 10x190 mm four self-sustains.

Wooden officials, open with all negative atmospheric phenomena, can over time to twist and quarrel.

But this option is a facade on an amateur. It should also be remembered that the nicknames should not be laid out, but strictly in accordance with (at least try) with the canons of this step, as described in detail in our article.

Moreover, it is necessary to estimate in advance, in what order to fix the plates on the facade so that the seams go smoothly. Otherwise, then you will have to break your head, how beautifully consolidate the bar, if the CSP went to the rotary.

Shek User forumhouse.

I will express my opinion on how most make the imitation of the step on the facade. A boards are taken 10-12 cm wide and just nailed on the walls. Such a fake literally hits the eyes. You do not need to be a specialist to understand that this is the usual layout of the board on the facade. Neither aesthetics, no beauty. This half-timber is assembled from a powerful timber secting from 20x20 or 25x25 cm. Filling the frame is on the same level with the outer plane of the walls. If it is imitation, then from the board with a width of a minimum of 15 cm, and it should come from the wall for no more than 2 cm, and even better flush. Then the view is normal, and the facade looks.

Of course, make a beautiful pseudo-contact for CSP - a difficult task. Repeated calculation and preliminary compilation of the design project of the facade, in which it is precisely indicated, how to lay the plates so that the seams go symmetrically.

Consider the simpler option of the falsefax on the example of a house Lutsenko.

Lutsenko. User forumhouse.

My wife and I bought a plot on which the log house was stood with a size of 6x6 m. The first winter showed that in the house it is cold, and the wind blows it. We decided to inspire him, attach the veranda and at the same time make the facade from the CSP under the Fakhverk.

To begin with, we show what the house was.

And how became.

The renovation process broke into a number of consecutive steps:

1. Purchase of material.

2. Installing the root.

3. Warming and installation of hydraulic protection.

4. Installation of CSP.

5. Printing and painting.

6. Production of naschelniks.

7. Installation of planks.

8. Final option.

Lutsenko.

Each edge of the leaf was fixed with 4 self-reserves + 1 in the center. Calculate so that all the screws are closed with straps. The case of the skin painted in the Pent.

CSP size on the facade Lutsenko.3200х1200х10 mm. Holes in the plates drilled in advance on Earth. Sheets saw with a circular saw with a disc with treaty attacks On the teeth.

Saw slabs should be on the street because of a large number of dust generated. Mount the CSP is best with the helper so as not to get tightly heavy slabs alone.

Another option pseudophammer on the CSP made SSERGEYA.

According to the user, he climbed the clearance between sheets, as the manufacturer recommends - laying the sealing cord with a diameter of 8 mm (at a gap of 6 mm). The cord (harness from foamed polyethylene) is interpreted in the seam by 2-3 mm.

From above, the junction is closed with elastic sealant.

The sealant layer was then smoothed by a spatula.

On this photo, the seam was covered with a harness, sealant and scratched structural paint.

The elasticity of the material allows you to smooth out the stresses arising in the seams of the national team.

The sealant retains the effectiveness of isolation under the influence of atmospheric precipitation, high humidity and high temperatures.

Important: Hats of self-tapping screws are accumulated by 2 mm in the stove, and then all fasteners also put the elastic composition. Dusty, with sandy irregularities and the facade peeled from dirt is necessarily ground and then paint structural paint.

The linings were drunk in advance in the size of the CSP, saddled, stained and only they were screwed, and the hats of the screws were carefully painted.

In this project in places where ostels are used, the joints are closed only by a harness, without using sealant.

Carefully prepared grounds, high-quality smooth saw Plates and strict following the recommendations of manufacturers of materials - the key to the high-quality facade.

In addition to staining CSP, the facade can also be separated by elastic plaster.

In this case, as when painting, if the seams are embedded using the technology "elastic harness + sealant", you can do without using decorative lining And get a smooth homogeneous wall with a beautiful texture.

CSP facade under siding

Judging by the portal user reports, such a CSP-based facade is also popular.

But by choosing this option, it should be prepared in advance to a large amount of work on sawing cement-chipboard.

Xmao025 User forumhouse.

I like the CSP, but I decided to do the most original and dissolve the plates with a circular on the "boards", and then mount them as siding.

After mounting the facade, the user plans to be primed it and paint acrylic paint.

In addition, when sawing fibro-cement siding, chips and scratches can be obtained, which will have to paint the scratch. Also, expensive trimming (the price of fiber-cement siding for 2015 went out about 930 rubles. Per 1 sq. M. m. 32 rubles. For CSP), which, in contrast to CSP, do not let me in the case. Another argument that turned towards cement-chipboard - the width of the fibro-cement siding is 19 cm, and the user wanted "boards" on the facade of about 31 cm wide. This reduces the number of horizontal planks, and therefore increases the speed of work, the installation time is saved and reduced costs.

The user figured out that it would be necessary to mount one and a half times more fibro-cement panels than "boards" sliced \u200b\u200bfrom CSP.

As a result, the user dismissed the plates using a circular saw to which the diamond disc from the "Bulgarian" diamond disk, (because these tools have different landing diameters for saw blades).

Egor Shilov

I bought a CSP of 1 cm thick and 1250x3200 mm sizes. The plates dissected for 4 bands, about 30 cm wide, fastened to the cut and painted on the place. The facade fully justified itself, during operation it was not falling off, the paint did not displease.

At the end of the article, we give the economic benefit of such a facade, which Egor Shilov calculated. So, costs for the manufacture of homemade siding from CSPwhere they entered: the cost of plates + their sawing + staining, including paint purchase - 480 rub. For 1 square. m.

Recall that fibrocemental siding cost 930 rubles. For 1 square. m. Total difference amounted to 450 rubles. The area of \u200b\u200bthe facade house is about 300 square meters. m. The total savings turned out to be 135 thousand rubles.

You can learn all about the facade based on cement-chipboard in the subject of facades from CSP, mounting, processing and finishing.

In the video - example right mounting « wet facade"According to expanded polystyrene.

Continuing the cycle of articles applications of CSP Building plates We present recommendations from manufacturers for processing CSP (cutting, drilling, milling, grinding), fixing the CSP (with the help of nails and screws, placement and execution of seams) and surface finish (color, plaster).

Recall cement-chipboard (CSP) - building material with unique propertiesused in the technology of "dry mounting". CSPs relate to the generation of modern composite building materials with properties that combine the strength and durability of cement with flexibility and simplicity of wood processing. The universal technical characteristics of the CSP have already fully appreciated all over the world.

Modern plates are manufactured by pressing a molded technological mixture consisting of chip shavings of coniferous rocks (24%), portland cement (65%), mineral substances (2.5%) and water (8.5%).

Describes the use of CSP plates for designing facades of buildings of any types.

Today on the Internet there is great amount Soviets and recommendations for working with CSP slates, but many of them do not meet the validity of reality. In order to figure out how to work properly with CSP plates, we turned to the recommendations of manufacturers.

Treatment of CSP.

Attention! To obtain a high-quality treated surface of cement-chipboard, a cutting tool made of solid alloys is used.

Cutting
With cutting (stripping, trimming) cement-chipboard on the object use manual circular saws With a disk diameter of 250 mm and the amount of teeth no more than 40. The speed of rotation of the disk 3000-4000 revolutions per minute.

To obtain a smooth edge, the cutting disk should be on the bottom surface of the plate for the lowest possible distance. Cutting plates are made from a back side to maintain the front side of damage.

Drilling holes.
For drilling holes in cement-chipstroke plates, manual electric cries with electronic revolutions are used. To drill single holes, you can use spiral drills from the HSS cutting material, for a long mode of operation - the drills of solid alloys are recommended.

Milling.
For milling cement-chipboard, manual electric milling mills with end mills equipped with a solid alloy attacks are used. Rotation frequency cutting tool in the range of 25-35 m / s.

Grinding.
Grinding cement-chipboard at the enterprise SOOO "CSP BZS" is not produced. In practice, when installing plates, local irregularities can occur in the joints of the joint, which should be removed by grinding. For this purpose, manual vibration, eccentric (orbital) or tapes are applied grinding machines. The grain of grinding material should be within 40-80 units.

Attention! When grinding, the upper fine coating layer is disturbed, which leads to the opening of the structure of the plate, an increase in water absorption, deterioration of physicomechanical properties. After the end of processing on the stove, it is necessary to apply soil to stabilize the surface and reduce hygroscopicity.

With cutting, drilling, milling and grinding of cement-chipstones, a large amount of dust is highlighted, so dusting devices and aspiration means it is necessary.

Fastening of CSP.

Attention! All connecting elements and metal structural elements must have anticorrosion coating. Before fastening cement-chipboard, make sure that the vertical and horizontal is the location of the framework elements, and find them in the same plane. All planes and edges of cement-chipboard before fastening must be projected. Special attention It should be given to priming faces.

Cement-chip plates are attached to the carrying structures using self-tapping screws and rivets (when attached to a metal profile).

In order to provide technologically right fastening Cement-chipboard, the main requirement is the observance of the step between the fasteners and the distances between them and the edges of the plates, according to the following scheme and the table.

Holes for self-tapping screws and rivets are drilled in a diameter of 1.2 times greater than their own diameter. To deepen the heads of the screws and rivets, the holes are pre-producing a depth of depth, exceeding 1.5-2 mm height of the heads.

For the attachment of the CSP without prior drilling holes, special self-tapping screws with a strengthened edge and a secret head, equipped with blades for the formation of deepening (spraying) under its dimensions, can be used.

Attention! The size of the screws and self-samples is chosen with the condition that the length of the pinched part was at least two thickness of the CSP plate and at least 10 diameters of the screw. When screwing the screws and self-tapping screws, an excessive force should not be made to avoid cracking of the stove.

The table shows minimum dimensions Screws and self-tapping screws used for fastening cement-chipstones to elements carrier carcasses Depending on its thickness and diameter of the heater of the metician product.

Attention! When using cement-chipboard for cladding walls, partitions and ceilings, it is necessary to put them with a seam, the width of which is 6-8 mm for the outer and 3-4 mm for internal use. The seams can be closed by an outer bar, put a wooden, tin, metal or polymer profile, or smeared with a plastic smear on the basis of acrylic resins or polyurethanes.

Surface trim CSP.

Cement-chips, like any chickening materials, are subject to a small expansion and shrinkage under the action of temperature change and humidity level.

At the joints of the plates, it is necessary to leave a gap for a thermal expansion that allows a linear expansion of the stove. In order to prevent the formation of cracks in the mixture for sealing seams, the width of the closed compensation seam should be 8 mm for external use and 4 mm for internal.

The easiest is the unlocked compensation seam.

Attention! Cement-chipboard are supplied from the manufacturer with a level of moisture content of 9 ± 3%. Intermediate storage before processing, as well as installations should be carried out in dry conditions. If this requirement fails to comply with this requirement, it is possible to absorb unacceptably the high amount of moisture, which can lead to damage in closed seams and / or in the places of fasteners, as well as damage to the paint coating of the surface of the plates applied at the work site.

The design of the end faces of cement-chipboard and seams are diverse. The most common systems are presented below. When using cement-chipboard outside buildings and for lining of walls, it is not recommended to grind the surface of the plates (except in cases where the grinding surface is provided by special requirements). Grinded plates in which wood particles are directly visible on the surface, as a rule, are used for only the flooring devices (due to harsh thickness requirements), as well as in special cases.

Attention! Regardless of the methods of the surface finishing of cement-palls, the mandatory primer is required for their planes and faces. Rollover sides of the plates are soaked up to their installation.

Coloring CSP Plate.
The easiest and most common way of surface finishing of the CSP is a painting with the formation of compensatory seams between the plates (open seams).

In this case, before applying paint to the surface of the cement-chipboard, it is necessary:
- deepen all screws by 1-2 mm in the stove;
- Clear contamination and deny the surface of the plate. In the case of fat or oil spots, you need to degrease them;
- with moisturized cleaning, it is necessary to dry the slab;
- Sharpen all the recesses and chips with a facade putty;
- After complete drying of putty, sanding covered places;
- clean and brand the facial side and the edge of the cement-chipboard (stabilizes the surface, reduces hygroscopicity, uniforms the base);
- Clean the slab color.

Attention! Paints must contain pigments stable in an alkaline environment. Unstable pigments can lead to changes in color shades.

Filling the compensation seams with elastic smears.
Filling the compensation seams is made by elastic plugs based on acrylic resins and polyurethanes. Silicone maps for cement-chipboard do not apply.

The main rule for the functioning of the compensation seam is the exclusion of trilateral adjacent in the seam, which causes the uneven load of the elastic filler, followed by the separation of it from the edges of cement-chipboard.

To do this, use liners made of polyethylene tape or cord from polyethylene foamed, which allows to obtain the adjacent of the elastic filler only to the opposite grades of cement-chipboard and evenly distribute the load onto the filler.

Plastering.
Plastering works on cement-chip stoves are carried out with an open seam and a seam, a closed finishing system or lack of straps.

Plaster works are carried out in cases where the surface of the stove should look monolithic and smooth, without visible compensation seams. As you know, with a change in relative humidity, an extension or shrinkage of CSP plates occurs. In order for these changes to do not affect the appearance of the plastered surface and did not lead to the formation of stripe (hair) cracks, it is necessary:
- attach to the design, previously primed plates;
- fill the formed compensation seams with an elastic dressing;
- make a plane wrapper of the working surface;
- pressed into the resulting layer of coating alkali-resistant glasswork;
- to apply the stripping layer of the splatlets;
- Make the final (finishing) surface finish.

Facing cement-chipboard with ceramic tiles or decorative stone.
When lining the working surfaces of cement-chipped plates with ceramic tiles or decorative stone for fastening and filling out the extension seams, it is necessary to use elastic mastic.

Adhesive mastic is recommended to apply for the whole working surface Plates. The extension seams between the plates are recommended to display, ensuring their coincidence with the seams of ceramic tiles and decorative stone. Otherwise, ceramic facing tile or decorative stone element, overlapping the connecting plates, should be glued only to one of the plates, leaving the place of overlap without adhesive mastic.

In rooms with insufficient ventilation for structures with a constant water load (bath, shower), pre-applied cement-chip plates should be used, followed by waterproofing spacing on them.

Frame house, like any other vacation home, requires external finish. To do this is used different materials: Lining, Siding, Sandwich Panel, etc. Stucco is used on a par with construction materials. This method is quite simple and can be implemented by the owners of the householders who do not have greater experience in construction and finishing.

The facade of the facade of the frame house is performed using two common technologies. In the first case, cement-chipsticks are used (CSP), in the second - overlay reinforced plaster In several layers on a metal grid. The plaster on the CSP is the most simple in terms of labor intensity, but this method is less durable. Even with proper observance of the technology of plastering, five years old on the walls of the house can begin to appear cracks in the joints between CSP plates. The imposition of special plaster on the metal grid takes a long time and requires a certain skill, but the result will cost the spent effort: it will be possible to recall the new finish of the outer walls after 15 years.

Stucco for cement-chip plates

CSP plates are a popular finishing material that is made of a mixture of sawdust, wood chips, cement and some chemical components. After preparing the mixture, it is despicable in the stove and dried, forming durable and waterproof plates, which are also completely fireproof. Square meter such a plate weighs 14-15 kg. All this in combination with a flat smooth surface makes cement-chipsticks universal option for country construction. In addition, they perfectly withstand longitudinal loads and serve their owners for many years.

CSP slabs for finishing walls of frame houses can be used in two technologies. The first technology is simpler and implies the installation of panels directly to the framework of the house through the layer of insulation and waterproofing. In the second case, to increase the reliability of the house design, the frame at first is trimmed by plywood or OSB plates. After that, small slats are attached to them, for which cement-chip panels are attached. And in that, and in another case, the plates are attached to a frame or rake with nails or self-tapping. For reliable attachment, they must be deepened into the tree to a depth of at least 2 cm. If the installation of the plates is made on drywall, only self-tapping screws are used as fasteners. Holes for them need to be made in advance with a drill and drill.

Since CSP plates are produced quite large areas, they can be chopped to finish the facade of the frame house under the desired grinder. When installing between adjacent plates, you need to leave a gap of 5-7 mm in order to avoid negative consequences strain after temperature drop. These gaps are not ignored: after the plates are installed and sustained some time, the joints are embarrassed by a sealant or other similar material. Then the extra layer of the material is cut, and the joints are closed with decorative straps.

Cement-chips are good because they have a very smooth surface and have good adhesion to most finishing materials. That is why they are the perfect surface for applying. decorative plasterwhich, everything else, is used to finish the walls from other materials. After processing the CSP plate with plaster, the wall of the house is very difficult to distinguish from the stone. However, due to the expansion of the plates, there may be cracks on the wall on the wall, so periodically it is necessary to smear the seams with a new plaster. You can go and other way: so as not to prepare the plaster every time, the owners of a frame house are enough to install decorative strips or panels on top of plaster. It is necessary to have them vertically and horizontally, that is, in all places of the potential appearance of cracks.

Stuccoings for frame houses

In addition to the classic decorative plaster, other types of facade are used to finish the facade of the frame house:

• Elastic plaster. A special type of plaster, which, as follows from the name, can slightly change its geometry. It is usually superimposed on the bottom layer of ordinary plaster to prevent the appearance of cracks. The elastic material is made on the basis of acrylic and withstands both strong frosts and severe heat with straight solar rays.

The lack of elastic plaster for frame houses can be attributed to its high cost. This material is relatively recently appeared in our country, and has not yet become widespread. However, many houses are already plastered by this composition, however, due to the long warranty (up to 10 years), it is not yet possible to check whether the figures specified by manufacturers are valid.

• Multilayer plaster. This composition differs from ordinary plaster, and requires special preparatory operations. The main requirement is to apply it only to the coating of OSB. Moreover, the plates need to be installed in such a way that the chips in them are horizontally. Only in this case, the OSB slab will withstand the additional weight of plaster and are not deformed when the temperature drops.

Before applying plaster on the OSB plates, the latter must be closed with a special flame retardant membrane. This is done in order to reliably protect the material of the insulation before shuttering. If you do not have the opportunity to close the wall with a solid piece of film, you can put it with stripes, overlooking them on each other. In addition, in front of the plaster of the facade house should take care of the additional protection of window and door openings. To do this, they are wrapped in the primary layer of waterproofing, on top of which the main film is stacked. Fastening of films is performed building stapler. As for the carcass of the house, the gap between the racks should be chosen as the same as when shearing siding or clapboard.

Stucco on the grid

Plaster in a frame house on a metal grid - another popular option outdoor decoration at home. The grid for this procedure should be steel; It is attached to the frame with the help of brackets, screws or nails. For the walls of a small area, you can take a grid in the form of a solid canvas that you need to maintain a vertical or horizontal corner so that in the middle it does not have and did not touch the lining of the house. In the corners, the grid is closed by a steel corner, or simply its ends are overwhelmed at each other. At the bottom of the wall, a metal plank is nailed, which fixes the grid and serves as a support for applying plaster. If the grid is installed without sagging, the probability of cracking when applying plaster will be minimal.

Put the stucco metal grid quite simple. Fiber fibers are added to increase strength to the solution. The primary plaster is applied a rather thick layer (up to 2 cm), but it is not necessary to align it too thoroughly. Drying the first layer occurs within two days at a temperature of at least 18 degrees above zero. With more low temperatures Drying time should be extended on one day. When this layer is dry, it should be installed a plastic mesh and apply a finishing layer of decorative plaster. It differs from the substrate only the lack of fiber fibers in a mixture and a thinner layer. If in the future you assume the wall color, the top layer should be aligned. The total thickness of all layers over the OSB plate should be two with a small centimeter. This value ensures the strength of the design and does not waste the house.

Applying decorative plaster

Decorative plaster can also be considered a relatively young technology, but, unlike elastic plaster, it has a great popularity as a finishing material for the most different surfaces. Decorative plaster in frame houses can be applied in one layer without waving. This is possible in cases where the finish coating will be installed on top of it: ceramic tile, a natural stone etc. Thus, the plaster itself will be the first layer of finishes. In addition, the plaster can be painted and varnished.

Modern decorative plaster are such that they combine excellent external data with protective properties. However, if your home is built in heavy climatic conditionsyou can additionally process his walls special compositions. In extreme cases, you can only handle the side that is in the sun or most often turns out to be rain. But keep in mind that additional coatings may worsen the gas-permeability of the walls, which, when coating only one decorative plaster, does not occur.
