How to lay chipboard on a concrete base with your own hands. Chipboard floor: nuances of the option on logs Sub-floor made of chipboard

When renovating a room, it is very important to carry out all the work efficiently in order to avoid unpleasant moments. Much attention Always pay attention to the walls and ceiling; the type of finishing material will depend on how smooth they are. No less significant during repair work the question of gender remains. Its repair is very important, since on a flat, prepared surface the floor covering will last much longer. Today, very often, in order to lay flooring, a floor is made of chipboard on joists.

Chipboard flooring is one of the effective ways make a subfloor for any type of floor covering. Using chipboard, you can create a perfectly flat surface on which you can safely lay finishing material. In addition, such a floor will increase the thermal insulation of the room, this is especially important for rooms located on the ground floor. In case of replacement or subsequent repairs, such a base can be easily dismantled and then reassembled. There are certain requirements that must be met when installing a floor on joists, compliance with which will make the final result reliable and durable.

Methods for installing chipboard sheets

Today, in order to level the floor, chipboard can be laid using two installation methods:

• direct laying on a cement base;
• laying slabs on wooden logs, this option is much more complicated than the first, but at the same time it is more effective.

It is important to remember that when laying chipboard on joists, it is important to control the ends of the boards. All joints must be located on wooden logs; under no circumstances should the joints be allowed to sag over the void. This may cause the slabs to break in the future.

The main advantages of this floor include:

• all communications can be carried out under the floor;
• if necessary, a layer of insulation can be laid between the joists to retain heat and reduce noise;
• the surface of such a floor will be almost perfectly flat.

Or a log bathhouse, or in someone’s apartment, this is always a very labor-intensive process. But probably the most important part of such work is the reconstruction of the floor. Today, wood is often used for this purpose. particle boards.

The popularity of this material is due to some important factors.

• Chipboard is an excellent material for leveling floors.
• Particle boards are a good base for a base coat.
• Chipboard serves as an excellent insulation material.
• The cost of this material is much lower than wood or, for example, plywood.
• Laying sheets of compressed sawdust is quick and easy.

You should not lay chipboard in a room where there is constant humidity. Dampness will quickly destroy the material. Ideal conditions For the operation of particle boards, the humidity is no more than 60% and the air temperature is not lower than 10 °C.

Tools for laying chipboard:

• roulette;
• pencil;
• square;
• hammer;
• metal ruler;
• Circular Saw;
• screwdriver;
• drill (how to choose a drill).

Materials for laying chipboard:

• dowels;
• self-tapping screws;
• nails;
• putty.

How to choose chipboard

Single-layer slabs are quite suitable for the floor. Such sheets have a small thickness, good grinding and high density. Another advantage of this material is the excellent absorption of paint and varnish products.

Important factors when choosing pressed boards are the tensile strength and the level of swelling in water. There are indicators that you need to focus on when purchasing such products. Thus, the tensile strength should be no more than 0.5 MPa, and the bending strength should be no more than 25 Mega Pascal. High-quality material should not swell in water by more than 30%.

Also great importance has a grade of particleboard. For the floor, it is necessary to choose only the first grade material. When choosing chipboard, the manufacturer is also important. Domestic manufacturers dominate our market. The quality of their products is very good. Therefore choose good material won't be difficult.

How to lay chipboard on a wooden floor

Before you begin installing particle boards on a wooden floor, you need to do research work.

• Check the condition of the boards and beams. Loose ones need to be nailed down, damaged ones need to be replaced.
• If there are pipes or electrical wiring under the floor, determine in advance the location for the hatch.
• Soak the boards with antifungal agents.
• If in wooden floor There are squeaks and they need to be eliminated.
• Remove skirting boards and other elements that may interfere with the quality installation of the material.

Chipboard laying method

You need to start laying particle boards from the corner of the room. There should be a distance of at least 10 millimeters between the slab and the wall. The joints of the slabs should be located in the areas where the beams are placed.

The chipboard is secured with self-tapping screws around the perimeter of the slab. The distance between the screws must be at least 30 centimeters. The hole for fastening must be of such a size that the head of the screw does not extend beyond the surface of the slab. All remaining material must be laid in a similar manner.

After all the sheets have been installed, you need to putty the joints. Then, when the solution dries, the surface must be sanded. If in the future there are no plans to lay linoleum or laminate on the particle boards, the chipboard must be covered with varnish. This will protect the floor from moisture getting inside.

Chipboard cutting

If you need to use only part of the slab, it needs to be cut. A circular saw is used for this. It is strengthened on a workbench and the board is cut.

How to attach chipboard

There are several options for doing this job. Nails. To use this material, you must first make holes in the slabs.

How to lay chipboard on a concrete floor

Install chipboards on concrete base possible in two ways. Both methods will make the floor equally comfortable and warm.

Laying chipboard directly on concrete.

To do this, the floor needs to be: cleared of debris; dry; align. To level the surface, additional screed filling is used. Chipboard sheets must be cut and treated with drying oil in advance. The material must be laid taking into account a gap to the wall of at least 1 centimeter. When laying pressed slabs directly on a concrete base, it is better to use dowels for fastening. In this case, you need to make holes with a hammer drill.

Laying chipboard on joists

The advantages of installing particle boards on logs are:

• great thermal insulation;
• the possibility of using additional insulation;
• no additional screed required;
• saving time.

Chipboard is not a strong enough material, so logs must be placed quite often.

In this method of laying pressed slabs, work must begin with the installation of logs. If there are gaps between the beams and concrete, fill the problem areas with wedges. The outer beams are installed at a distance of 250 millimeters from the walls. All subsequent ones are in an interval not exceeding 400 millimeters.

The logs are fixed in one plane. Check using a level and secure with anchors. Next, lay the chipboard sheets. They are distributed in such a way that the joint of the slabs occurs exactly in the center of the log. Attach with screws around the perimeter at a distance of no more than 30 centimeters.

The heads of the screws must be below the surface of the slab. The seams between the plates are treated with putty, dried and sanded with sandpaper. On the floor prepared in this way, you can put laminate, linoleum or hide it with varnish.

If desired, the concrete floor can be additionally insulated. To do this, the insulation must be inserted into the sheathing or placed directly on the concrete base. This will not only create greater thermal insulation, but will also protect against excess noise. Any filler can be used for these purposes. The most popular are technical cork and isolon.

Cork, with a fairly small thickness (from 3 to 10 millimeters), has very good heat-insulating characteristics. At the same time, it is illogical material. But its main disadvantage is the price. The cost of such products is quite high.

As for isolon, this material is very easy to use. It is rolled out on the surface and cut off right size, the joints are glued with ordinary tape.

Let's sum it up

If you do not have the skills for such work, you can contact specialized companies. Many companies offer their services in this area. The price for such installation depends on the quality of the material, installation method, and amount of work. Each company has its own price list, which indicates the price of services. Using these recommendations, you can make the floor in your home warm and comfortable. After all, this is the key to the comfort and health of the whole family.

Chipboard sheets are used to level the floor and create a base for various types of external coverings. The material is popular due to its low cost and ability to perform self-installation. In terms of their characteristics, chipboards are superior to many similar materials. This type of material occupies one of the leading positions in its field and deservedly enjoys the authority and respect of builders. The versatility of application and installation allows many types of sheets to be made from sheets of this type. structural elements, as a rule, internal structures of premises.

The article will tell you about the advantages and disadvantages of chipboard, about methods of installing floor coverings on various bases made of this popular material.

Advantages and disadvantages, characteristics of chipboard

Chipboards are produced by pressing wood chips and phenol-formaldehyde resin, which acts as an adhesive substance. The thickness of the sheets varies from 16 to 24 mm. Sheets have a range of densities, safety classes and sizes. The main dimensions are 250x185 cm, 350x175 cm. There is a variety of chipboard sheets - tongue and groove with increased moisture resistance. Slabs are available with and without various coatings. Coated products have a longer service life and improved performance. The tongue-and-groove sheets are not joined together, but with a tongue-and-groove connection.

The main advantages of wood-based material are the following:

• Relatively low cost (boards are much more expensive);
• High compressive strength;
• Rigidity and staticity;
• High-quality smooth surface, which makes it indispensable when installing floors;
• Versatility for use various types external floor covering;
• Possibility of installation on various bases;
• High rates of thermal and sound insulation;
• Long service life subject to installation and processing conditions;
• Ease of installation - due to the large overall dimensions of individual elements and relatively low weight;
• Good resistance to mold and mildew.

There are also certain disadvantages of chipboard:

• Harmful effects of formaldehyde resin on human health. Tongue-and-groove chipboard sheets are produced using a different type of material that is neutral to humans.
• Impact brittleness. This drawback negatively affects the installation process - when struck, the corners of the sheets may break off, and so on.
• The material quickly loses strength and collapses when exposed to moisture.
• The material is flammable and fire hazardous.
• When fastening slabs, you can only make through fastening through holes, since the slab material has a low density and does not fix the fastening element.
• The surface of the material without coating is subject to severe abrasion and wear.

To protect the material from moisture, it is treated with varnish, primed and painted, and so on.

Installation of chipboard sheets

Sheets are used in the construction of the floor base for finishing coatings, less often used for finishing use. In the final version, high-quality and effective measures are taken to process and strengthen the surface of the sheets - painting in several layers, using non-abrading paints, processing with special compounds, etc. Depending on the design of the floors, the sheets are laid with some differences in methods and techniques. First you need to take quality measurements and develop a sheet laying scheme. The scheme is developed based on the smallest number of joints formed between the sheets. According to the general method, sheets are laid with a gap from the wall of at least 15 mm to compensate for possible thermal expansion of the material.

For installation you will need the following set of tools:

• Electric jigsaw, hacksaws for wood and metal;
• Screwdriver;
• Hammer, small axe;
• Planer (not always);
• Screwdrivers, chisel;
• Construction level, tape measure;
• Spatula and others.

Laying on plank floors

Laying sheets on old plank floors is done as follows. The floor surface is cleaned of dust, washed and dried. Next, the boards are re-attached to the (existing) joists. This is done using wood screws and a screwdriver. Each board is reattached to the joists - this event will eliminate the occurrence of creaking floors.

Then the first sheet (top sheet) is laid. Installation is carried out maintaining the appropriate clearance from the wall. Fastening is done through prepared holes using screws. The screw head is turned until the head is recessed by 1 - 2 mm. Nails are used much less frequently for fastening. Fastening is done around the perimeter in increments of 20 mm and across the total area in increments of up to 50 mm. The horizontal surface of the installed sheet is checked with a building level; all subsequent sheets will be oriented towards it.

Wooden plank floors, as a rule, have a good overall horizon, but in case of horizontal deviations, strips of plywood are used for leveling. After installing and checking the first sheet, all subsequent sheets are installed, checked and secured in stages according to the prepared diagram. It is better to trim sheets to the required sizes electric jigsaw. If you don’t have one, use a hacksaw for wood (it can also be used for metal, but its use is not very convenient).

After complete installation of the sheets, seams, joints and fastening holes are processed and sealed (putty and other materials of a similar type are used). If it is necessary to increase moisture protection measures, various measures are carried out - priming and painting, treatment with various compounds.

Laying on joists

If there is a concrete floor with large deviations in height at different points in the room, chipboard is laid on wooden logs. Used as a lag wooden beam with a side size of at least 40 mm. The wood is pre-treated with protective compounds.

The logs are laid with a certain step depending on the thickness of the material and the configuration of the floor surface. With a sheet thickness of 16 mm, the pitch is recommended to be at least 100 mm, with 24 mm - from 400 to 500 mm. The logs are laid with the first one horizontally. All subsequent logs are aligned along the horizon of the first log. For leveling, various substrates are used, uneven floors are smoothed out, and the wooden beam is trimmed with a plane.

After installing the logs, the top chipboard sheet is installed. Subsequently, the material is laid and secured according to the general method (described in the previous section of the article).

Laying chipboard on a concrete base

Chipboard is laid directly on the concrete base. To do this, a set of works is first carried out to level the concrete surface and form a horizontal line across the entire surface of the floor. These works are carried out using various ready-made mixtures, cement mortar, and so on.

The sheets are laid according to the diagram and attached to the concrete through the holes using dowels. Processing of joints and fastening points and moisture protection measures are carried out.

When using tongue-and-groove chipboard, fastening is done in a different way. The sheets are laid according to the scheme, they are connected in series and glued together using a tongue-and-groove fastening. To create a tighter joint and high-quality gluing, the sheets are wedged with wooden wedges into the gaps from the walls.

Conclusion

Chipboards – perfect solution to create a smooth floor surface. Due to the high-quality ratio of price, quality and ease of installation, they are very popular among craftsmen. Application in non-residential premises is mandatory, but in residential premises it is still better to use special (safe for humans) types of chipboard.

When renovating an apartment, you often have to do floor repairs. This is quite a labor-intensive and difficult task. To work you need to have a tool and some professional skills.

Construction of a “subfloor” made of sheet materials.

But in most cases, you can do all the work yourself and update the floor with your own hands.

What is needed for work

To complete the work you need:

• chipboard sheets;
• wooden logs (optimal section 5x10 cm);
• screws for fastening;
• carpenter's saw;
• hammer;
• dowels;
• screwdriver;
• nails;
• construction stapler;
• nail puller;
• Sander.

Preparation for laying chipboard

First you need to carefully inspect the floor and identify all its defects. Before inspection, it is necessary to remove all furniture from the room, remove dirt and debris. If upon inspection numerous deficiencies, uneven wear, and rot appear, a complete replacement of the deck may be required. In this case, you will have to dismantle the entire floor.

To dismantle the old floor, you need to remove the baseboards and disassemble the entire floor or part of it that has become unusable. The logs are cleaned of dirt and checked for the presence of mold, mildew, and insect larvae. Some damaged joists may need to be replaced. All new and old wooden structures need to be treated with an antiseptic composition.

As a new coating you can use: floorboard made of oak, maple, larch wood; waterproof plywood 16-18 mm thick; chipboards (chipboards). They consist of wood shavings, which are mixed with resin and pressed while hot. As a result of pressing, slabs with a thickness of 10 to 30 mm are obtained. They are used in the manufacture of furniture and in construction. For floors, material with a thickness of 18-20 mm is most often used. The logs under the slabs should be placed at intervals of 400 mm.

Tongue-and-groove floor panels are produced from chipboard. These panels can also have a smooth edge. Any panels begin to be laid from the corner of the room. There should be a distance of about 10 mm from the edge of the material to the wall along the entire perimeter of the room. The edges of the panels can be coated with PVA glue to achieve a tighter and more durable connection. The end joints of the panels must be placed in a checkerboard pattern along the floor surface.

Laying chipboard on an old floor

A person is in constant contact with the floor. Therefore, its arrangement and decoration are important. This part of the house or apartment should be level, highly durable, and not difficult to clean. The floor must be sufficiently warm and dry. Quite smooth and durable floors can be made from chipboard. They can serve as a basis for laying carpet or polymer coating. Sheets of this coating are easy to use. No special tools are required to process them. There is not much waste left after work. You just need to try to cut the material economically.

Chipboard on the floor - great option for repairing and leveling old floorboards. You just need to attach the sheets to the floor surface, ensuring the correct joints. To ensure sound insulation, a layer of construction felt can be placed underneath them. In this case, it is recommended to choose chipboard with a thickness of 21 mm or more. The material is attached to the surface of the old floor most often using screws and self-tapping screws, less often using glue.

A very smooth floor surface can be achieved by using chipboard with dovetailed edges. It is not recommended to lay floors made of chipboards that contain formaldehyde resins in residential areas. During operation, resins evaporate from such material, releasing large amounts of toxic substances.

Before laying on the floor, it is recommended to treat the material twice with drying oil. Very high density chipboards are available. In this case, you can pre-drill holes of a smaller diameter for self-tapping screws. The caps of the fasteners should be deepened by 0.5-1 mm, then the recesses should be sealed with putty.

When installing thermal insulation under chipboard, we must not forget that the sheathing must be positioned perfectly evenly in a horizontal plane. The sheets should rest on it with their entire surface. It is not recommended to make the distance between the longitudinal elements of the sheathing more than 40 cm. Only in this case will the chipboard floor have sufficient strength. All slab joints must be thoroughly sanded. Otherwise, even the most invisible difference can become noticeable when laying a polymer or carpet covering.

To fill small cracks and recesses from self-tapping screws, it is not necessary to use standard putty. You can make your own putty by mixing small sawdust, remaining after cutting the slabs, and PVA glue.

After laying chipboard over the entire floor, you can apply a protective coating consisting of several layers of polyurethane-based varnish. The gap left at the walls is closed with baseboards. In the case where they plan to put another floor covering on the chipboard in the form of carpet, cork, linoleum or laminate, the baseboards are installed after all work is completed. Skirting boards can be made of wood or plastic. If carpet is laid on the floor, then the baseboard can be wrapped in the same material and then attached in its place. The plinth made of any material must fit snugly to the floor and to the wall.

It is not recommended to lay chipboard on the floor in rooms where the load on the floor is quite high. Such places are offices, shops, industrial and other premises visited by a large number of people. Such slabs should not be used in rooms with high humidity, under the influence of which the pressed material begins to deform and quickly collapse.

In this post: a reader's question regarding the use of particle boards as flooring. In other words, is it possible to use chipboard for flooring?

If you know the answer to this question and have practical experience, then write about it in the comments. You can also ask your question in the “Questionnaire” section and get an answer from visitors to our website.

Reader question:

“The floor in the house is concrete, the thickness of the screed is about 60 mm. I wanted the floor to be warm, so the idea arose to use chipboards for this. True, at first I wanted to use plywood for this purpose. However, it is significantly more expensive.

Accordingly, the following is of interest:

Is it possible to lay chipboard on the floor?

What confuses me...

• First of all, the issue of environmental friendliness. I read that such slabs emit harmful formaldehyde.
• The second is moisture resistance. For example, if there are small water leaks, is this dangerous for the chipboard?
• Third, what is the service life of such a coating? Let's say the conditions are ideal - dry, etc. Any guesses on how long this floor will last?
• Fourth, is it necessary to cover the chipboard with some kind of paint and varnish in this case? Will this protect against formaldehyde release?

Construction specialists, please tell me.”

Is it possible to use chipboard for flooring?: 6 comments

In principle, it is possible to use chipboard for the floor, but there are really important points that are worth paying attention to Special attention. I answer your questions point by point:

1. The issue of environmental friendliness worries you for good reason. Formaldehyde emissions are actually present. Moreover, plywood, in my opinion, will not solve this problem. Although... perhaps plywood will contain fewer such harmful substances.

2. Chipboard is afraid of moisture. Therefore, any contact with water is extremely undesirable.

3. Such a floor can last for decades (under appropriate conditions).

4. Regarding protection from formaldehyde with paints and varnishes, I can’t say for sure. And here appearance and the wear resistance of the floor can be significantly improved with the help of such coatings.

P.S. I would lay real oak parquet on the floor :)

If you decide to use chipboard for the floor, then choose and check. Don't buy cheap material. Only serious stores with appropriate quality certificates. Now there are many low-quality materials on the market. There may be much more formaldehyde in them than you think. Health is more valuable.

Pay attention to the chipboard called “Super E” or “E0”. This is an ultra-safe material that has been used in Europe for a long time. In ordinary chipboards, formaldehyde resins are present by default. With the help of them the chips are connected to each other.

How many chipboards are there in the house? I would not use this material for flooring. The reason is the same - harmful secretions.

Look towards solid wood. What they said here is correct about real wooden parquet. Yes, it's expensive. But it’s safe and solid.

Can. For protection against resins, according to sanitary rules, painting is sufficient. Better, incl. from the point of view of moisture protection, lay linoleum. There is also PVA-based chipboard - it is safe, but less moisture resistant. OBI sells this.

We decided to choose wood - parquet (oak). Yes, it's expensive. However it looks great! And chipboard is pressed shavings with some kind of resin. It is unknown how this affects health. Moreover, the chipboard that was made before is one thing. And now they have invented so many different chemistry... I suspect that modern stoves have their own characteristics (not for the better). In a children's room, parquet is still better.
