Today, the CSP plate has gained popularity: the use of this material for the floor is very convenient. This is due to several reasons, the first of them is absolute environmental friendliness, the second - at a low cost. The basis of the plate is exclusively natural raw materials. Mineral substances act as binding components, which do not emit poisons and microelements during operation, which would be dangerous to human health. Among the ingredients of the canvas can be identified wood chips, water, Portland cement, as well as special additives. In the production process, the listed components are connected and go through the pressing stage.
DSP application for flooring
Today, the decoration of the floor area with plates of DSP is quite common. This material is characterized by excellent thermal insulation properties, in addition, it can be used in conditions that are characterized by high humidity. After laying the slab, it will be necessary to protect it with a primer or water-repellent mixture. The canvas will last for a long time, as it can withstand heavy loads. Depending on what traffic will be in the room, you can choose a plate with a more or less impressive thickness.
Despite the fact that the DSP board has excellent operational characteristics, the application for the floor must be accompanied by compliance with all installation rules, only then will it be possible to preserve all the qualities of the material. With the help of such a plate, it is possible to make perfect leveling of the floor surface in a short time. The use of this material allows to reduce the period of work. The floor will be strong and reliable, and construction costs will be significantly reduced.
DSP Characteristics
The composition of the material is 24% of wood chips, 8.5% of liquid, as well as 65% of cement, which ensures the durability and strength of the plate. In addition, among the ingredients there are 2.5% hydration impurities of the type of water glass and aluminum sulfate. Depending on the parameters of the floor, you can choose slabs that have dimensions equal to 3200 x 1250 mm, while the thickness can vary between 10-40 mm. But, according to the norms, the plate can be made with other parameters, the deviations in this case depend on the thickness.
Density and surface features
Considering the properties of a DSP board, it is worth paying attention to the density, which should not exceed 1300 kg / m 2 , while the humidity can vary between 6-12%. When exposed to water for 24 hours, the canvas should not swell by more than 2%, and the plate can absorb moisture in a volume of about 16%. Tensile strength is 0.4 MPa.
The surface of the material must be roughened, and grinding will influence the degree of roughness. If the manufacture is carried out according to GOST 7016-82, then the roughness of the plates will be more than 320 microns, but the canvas may not be polished, then this figure is within 80 microns.
Varieties of DSP
DSP-plate, the use of which today, as already mentioned, is becoming increasingly popular, is produced on modern equipment in several varieties. These are, for example, plates whose thickness is only 4 mm. The resulting material does not imply the need to perform grinding, which, when implemented, becomes the reason for the increase in cost. Slabs with smooth embossing are becoming increasingly popular. They contain small elements, the size of which increases closer to the center of the canvas. Using this material, you can get a floor that will look like natural stone. That is why the canvas after laying does not need to be further trimmed.
Advantages of DSP over other materials
If you have not yet decided which floor covering will be laid: fiberboard or DSP board, the use of these materials for the floor, or rather, their qualitative advantages, it is worth considering in more detail. Despite the fact that the market of modern building materials has a great many plates for repair work, DSP can be considered a leader. So, if we compare a DSP sheet with a fiberboard sheet, then the first is much stronger. In addition, the cement-bonded particleboard has such a quality as frost resistance, which makes it possible to use this material as flooring in houses that are not used for a whole year, but only in the warm period.
DSP-plate, the use of which is very popular for the floor, is also distinguished by its resistance to fire, as well as impressive temperature variations. In addition, she is not afraid of parasites, including fungi, mold, mice and insects. After laying the DSP, the surface can be finished at your discretion - it can be painting, laying tiles, applying plaster, etc. If you don’t know how to finish the floor after laying, you can think about how to do this in the case of traditional wood . A floor with a coating of DSP will gain the quality of a soundproofing with an index of up to 30 dB.
If you need a sufficiently strong surface, then you should choose a DSP: a cement-bonded particleboard just has such qualities, they are due to the fact that the canvas is based on three layers, two of which (external) are made of fine chips, while the inner one consists of longer particles. This gives the material elasticity, high density and hardness. Do not be afraid that during operation the plate will delaminate.
Preparatory work
DSP-plate, the use of which is considered in this article, involves the use of self-tapping screws when working with it. You can purchase canvases with a thickness in the range of 1-1.5 cm. As a rough coating, it is permissible to use wood or concrete screed. If there are lags on the floor, then the installation of the DSP can be done on top of them. Cutting the material is recommended with a fine-tooth hacksaw blade. This will reduce the amount of dust formed, and the edges will be as neat as possible. The sheet initially only has to be cut, laid on a flat surface, with the groove facing down. Next, the knee must be put on most of the canvas, and pull the smaller one towards you. In the required place, the plate will have to crack along the cut.
If in the process of repair work it is necessary to bypass the pipeline system, then on an element with the same diameter it is necessary to apply a solid oil and lean it in the desired section of the plate. This will allow you to mark the edges for cutting. Cutting can be done using the “crown”. If you need to get a hole that has significant dimensions and has uneven edges, it is recommended to make an incision, observing the perimeter, and then carefully knock out the resulting element with a hammer.
Markup
Before laying, it is necessary to prepare sheets that will correspond to the parameters of the room. For this, the canvases are laid out, and then markings are applied to their surface so that it is possible to carry out the correct cutting. After the sheets are turned into blanks, they should again be laid out around the room and numbered - this will eliminate errors.
Features of laying DSP on the floor
Before laying the DSP on the floor, the cement-bonded particleboard should be removed from the room in order to make it more convenient to work. Its laying is carried out on glue or self-tapping screws, depending on the characteristics of the rough floor. If it is supposed to be laid with glue, then it is preferable to prepare it using a construction mixer, which will eliminate the presence of lumps. However, a drill with a nozzle must be set to low speed. Manually achieve this result is unlikely to succeed.
Clearance
A DSP board, reviews of which, as a rule, is only positive, can be laid on the floor after the master is able to distribute the glue on the surface of the draft base. This must be done with a notched trowel. When laying the following sheets, it is necessary to provide a temperature gap, which will eliminate the deformation of the paintings when changing their sizes. The gaps formed can be filled with the same adhesive mass. After the floor of the room is completely covered, it is necessary to leave it until it dries. Only then can you start laying the decorative coating.
The technical characteristics of the DSP slab are such that it is able to replace the concrete screed. And the advantage of the canvas is that it weighs much less than the solution, while it is easier to lay it. In addition, the floor after completion of work acquires heat-insulating and noise-canceling properties.
DSP Reviews
Many consumers today speak very positively about DSP. They emphasize that in tandem with this material there is no need to use additional heat and noise canceling materials, which saves on repair work.
DSP-plate, reviews of which are only positive, is also appreciated for its low cost. Consumers note that they do not have to do wet work, which is accompanied by high labor costs. When laying sheets, the master only has to follow the correct position of the canvas in relation to the horizontal, because the sheets themselves have ideal linear dimensions. In addition, customers note that they choose DSP because it is universal, because it can be used not only for leveling the floor, but also for the construction of walls, fences, partitions and much more, including the production of furniture that comes out very competitively priced.
Where else is the DSP slab used for the floor? The reviews of the builders allow us to conclude that this material often has to be laid in the rooms of bathrooms. She's great for this. Some inexperienced craftsmen say that the stove is quite fragile. Perhaps this is perhaps the only negative point. However, such a statement is true only if handling the material is extremely careless.
DSP cost
Technical characteristics of the DSP board attract buyers, as well as the cost of this material. The price will depend on the parameters of the canvas. So, a sheet of 1250 x 2700 mm, which was produced in Russia, can be purchased for 675 rubles. It is worth counting that the material is usually sold in packs, each of which contains about 83 sheets.
The dimensions of a DSP board, as mentioned above, can be different. Parameters can be selected for a particular room. In this case, it is necessary to take into account the purpose of the room, as well as the intensity of its use. The latter circumstance must be thought out, since it is the floor that is subjected to the most impressive loads. If you lay a slab of insignificant thickness in an office where there is a lot of traffic, then after some time the finish coating will need to be repaired, which will make the process more expensive.
