Chipboards are frequently an essential part of installing concrete floors. A well-chosen chipboard type and adherence to installation guidelines can significantly impact the longevity and functionality of your floor. A strong foundation is essential for any flooring material you intend to use, so make sure you know what to look for in chipboards and how to lay them correctly on a screed.

This post will explain the essential specifications for chipboards used in concrete flooring and offer helpful advice on how to lay them on a screed. Having a solid, level floor that lasts for many years is possible whether you hire a contractor or are a do-it-yourself enthusiast.

We’ll go through everything you need to know to complete the task correctly, from choosing the appropriate grade of chipboard to adhering to the right installation procedures. Let’s get into the crucial information needed to successfully complete your flooring project.

Requirement	Description
Chipboard Type	Use chipboards specifically designed for concrete floors, often labeled as moisture-resistant or high-density.
Thickness	Choose chipboards with a minimum thickness of 18mm to ensure durability and support.
Screed Preparation	Ensure the screed is fully dry and level before laying chipboards to avoid uneven surfaces.
Installation Method	Lay chipboards with staggered joints to improve stability and reduce the risk of gaps.
Adhesive	Use a suitable adhesive for chipboards to secure them properly to the screed and prevent movement.
Edge Treatment	Seal the edges of chipboards to protect them from moisture and prevent swelling.

Is it possible to lay it on a screed??

Ideally, the best material for leveling concrete screed is chipboard. Since this can harm the cladding, the base in this instance shouldn’t have any major damage or noticeable height variations.

The provided material is frequently used to level floors in homes and offices because of its easy fastening. permits self-installation with standard tools.

Requirements

The latter needs to be properly prepared before you purchase the necessary quantity of chipboard to lay on it. The ensuing adjustments are performed:

• the floor is cleaned using an industrial vacuum cleaner or a mop with a brush soaked in water;
• a visual inspection is carried out for the presence of chips, protrusions and cracks;
• the recesses are sealed using a cement mixture;
• the cracks are expanded and also covered with a cement composition;
• the protrusions are ground down to the level of the base;
• one or two layers of primer mixture are applied to the surface.

This method will ensure that the surface is ready for chipboard installation. Dust from concrete doesn’t get in the way of work. Because the laying is done end to end, it is protected from above-ground moisture and debris infiltration.

Pie bottoms

In order to form an even and superior coating with chipboards, you must make the following cake:

1. Concrete screed. Pour in an even layer to obtain a coating without damage or external defects. If a new base is being formed, a grinder may be used to achieve optimal evenness.
2. Primer. Apply in one or two layers. Provides protection against the formation of cement dust, increases the strength of the screed surface.
3. Chipboard. Installed using self-tapping screws. Ensures tight joining of slabs to each other.

At least 8 to 10 mm should separate each slab when they are laid. This makes room for technological advancement when temperature and humidity levels fluctuate.

How to choose material?

The choice of chipboards is crucial; they need to match the requirements for strength and load resistance. Single-layer slabs will be a good choice because of their higher density and ability to be ground until the ideal evenness and seams are smoothed. The ability to process with paint or protective varnish is an advantage.

The following characteristics make the sheets ideal DSP:

• tensile strength up to 0.5 MPa;
• a bend of up to 25 MPa;
• swelling of water no higher than 30%.

Choosing an appropriate variety is a crucial step. Only the top layer of wood-bearing plates is used for flooring.

The price of a sheet typically begins at 1000 rubles.

Do you need preparation?

It is necessary to prepare the concrete screed before installing chipboard slabs. This will assist in achieving the most uniform and stress-resistant coating possible without future distortions or breaking.

Do a visual inspection for flaws and bumps at the beginning. If there are voids and fissures, a cement blend is used to fill them.

The protrusions have been polished to match the primary surface. In order to prevent more damaging processes, it is also advised to apply a primer to the surface after cleaning from concrete dust.

Preliminary actions

Buying the appropriate quantity of material is crucial. Making calculations and applying markings are essential for making the right choice of chipboard. It’s best to leave a reserve of at least 10%, regardless of the quantity of sheets acquired, as this will solve the issue in the event of unintentional damage.

Accurate computations are also carried out. You must first precisely measure the room’s size. Three slabs, each measuring 2440 by 1830 mm, must be selected. If you choose a larger format (3060×1220 mm), the same amount of material is needed.

Necessary consumables

Particle boards the proper size and thickness will be needed for the installation process on a concrete base. The size and complexity of the room determine these parameters. Dowels are also required to create a sturdy connection.

Wooden blocks composed of dense, moisture-resistant wood are required if you intend to install slabs on joists. Just in case, it is advisable to treat with an antibacterial composition.

List of tools

For covering a concrete foundation with chipboard sheets You need to make sure you have the following resources ready in advance:

• saw;
• construction pencil;
• drill or screwdriver;
• roulette;
• ruler;
• hammer.

This tool set makes it possible to cut and lay material on location. The necessary length and width of the floor are formed, and the joints are hardly noticeable.

Complete step-by-step installation instructions

The base needs to be cleaned, washed, and dried before you can install tiles on a concrete screed. In the event that a screed is not available, the surface is also leveled beforehand.

The following is the work order:

1. Before installation, the material is cut into sheets with the required parameters in advance. You must act with caution in rooms with a non-standard shape, the presence of a bay window, projections or columns.
2. At the next stage, the material is treated with drying oil to impart protective properties.
3. Direct installation is carried out using dowels. Holes of the required thickness are made in advance for them. We should not forget about making indentations of about 1 cm from all walls and ledges in the room.

Features of fastening to logs

In the event that the floor is not sufficiently level, fastening is done using wooden logs. Because you don’t need to lay a concrete screed, this alternative option saves a lot of money and time. Both improved thermal insulation and some degree of sound insulation are provided by this. To increase comfort during the winter, insulation can be added to the frame’s interior.

The logs must be laid with the least amount of step possible because chipboard does not fall under the category of the most durable materials. If not, there is a risk of quick damage to the surface and the upper decorative layer under severe pressure or heavy traffic.

First, wedges are used to install logs, which occupy the space between the concrete and beams. The logs that are installed closest to the walls are spaced 25 centimeters apart. Keep a maximum distance of 40 cm between the logs.

It is necessary to fix the lags on the anchor in a single plane. Simultaneously, evenness needs to be continuously assessed with a level in order to promptly address any issues that arise. Around the entire perimeter, the chipboard slabs are fastened to the logs in increments of 30 cm.

The fasteners are recessed slightly into the material when connecting. After applying putty and allowing it to dry, the joints are sanded to create a smooth surface.

What difficulties might there be??

Making mistakes when installing chipboard boards on a concrete foundation is crucial. The surface needs to be examined and cleaned thoroughly. The material will not remain in one place for very long and will not form a single plane if there are large variations in height and unevenness.

For chipboard to be directly mounted on joists, there must be a tiny space left between the joists and fasteners. In any other case, the material might sustain damage.

How to lay on an uneven surface?

In the event that the surface is not sufficiently level, a dry screed can be set up. Expanded clay in various fractions is mostly used for this purpose. After being poured, the material is leveled off the floor.

The last step involves the installation of chipboard sheets, which are then filled with a mortar made of cement, sand, and plasticizers. Subsequently, a second layer of slabs with finished material already applied can be used to level the area.

Average prices for professional services

When chipboard is applied to a concrete base You can carry out the following kinds of tasks:

• elimination of surface irregularities;
• forming a frame and laying lags with significant differences in height;
• pouring concrete screed;
• chipboard floor installation.

The average cost of installing a chipboard floor is 300 rubles per square meter.

For concrete floors to be durable and functional, the right chipboards must be chosen, and they must be laid on a screed correctly. The chipboards must be robust and able to withstand moisture in order to withstand the demands of a concrete surface. In addition, a smooth, stable, and long-lasting floor is guaranteed when the proper laying techniques are followed. Gaining an understanding of these specifications aids in producing a high-quality finish that satisfies both functional and aesthetic requirements.

Advantages and disadvantages

Chipboard is an all-purpose material. which offers a relatively flat surface and a high-strength coating. In order to cut costs, material is frequently chosen by builders and owners of residential and commercial spaces.

The benefits of using chipboard to level the concrete screed are as follows:

• partial sound insulation is provided;
• increased strength during proper formation of the floor surface;
• high density;
• additional insulation properties;
• relatively low costs;
• fairly high speed of installation work;
• you can lay the material yourself without the involvement of professional craftsmen;
• the ability to create a surface of any shape due to ease of processing;
• no complex tools required.

Because the slabs are relatively large, you can complete the work by yourself. Processing is simple because a sharp construction knife or jigsaw are frequently sufficient. Standard tools are used to safely complete the installation.

Simultaneously, relatively small strength characteristics can be distinguished when compared to plywood or wood. High humidity rooms shouldn’t be finished with materials you choose. The floor is unaffected by brief exposure to water, but you will need to disassemble the floor and the chipboard base entirely in the event of even minor flooding.

Reviews from builders and users indicate that these coatings can’t be applied properly on a very uneven base. Furthermore, it’s not always relevant to lay chipboard over a dried expanded clay screed. Additionally, chipboard panels are the best material for minor imperfections.

What types of coatings are placed on top?

The following floor coverings with decorative qualities can be installed on a chipboard floor:

• ceramic tiles;
• porcelain border;
• laminate;
• engineering board;
• parquet;
• Parquet board.

There are a lot of coating options available. But a standard or high baseboard must be installed because there are gaps all the way around the room. Another benefit of it is that it can be used for covert laying. Simultaneously, you do not need to construct extra hiding places or firmly post the room’s walls.

DSP can function as a stand-alone coating, but you must select a material that is reasonably thick and dense. Most of the time, a second streaming layer is added to provide the appropriate shade for the floor.

For a long-lasting and stable flooring system, selecting the appropriate chipboards for concrete floors and adhering to installation guidelines are essential. Chipboards offer a sturdy foundation for a variety of floor coverings, but their usefulness is contingent upon fulfilling particular specifications and being positioned precisely on a screed.

Make sure the chipboards are sturdy enough to be used as flooring. They ought to be able to withstand moisture and support a substantial weight. Over time, problems like warping or unevenness can be avoided by properly laying the chipboards and preparing the screed surface.

You can create a sturdy, long-lasting floor that efficiently supports your building or remodeling project by adhering to these recommendations. In addition to extending the life of your flooring, proper installation improves the functionality and comfort of your room.
