How to make a floor from OSB: features, laying technology, recommendations and reviews

OSB board is a modern building material that, according to its characteristics, has successfully replaced chipboard and plywood. These oriented strand boards are used both in the construction of frame houses and for insulation. Also use these products for the arrangement of rough coatings. OSB flooring is a great opportunity to level a concrete screed or a wooden floor inexpensively and with minimal effort.

What is OSB?

Oriented strand board consists of several layers of wood chips pressed and then glued with special waterproof resins. Glue it in three layers. On the outer sides, the chips are placed along the length, inside - perpendicularly. This solution gives the new building material a special strength.

Types of OSB boards

In construction work, as well as in the repair, several types of these plates are used. So, OSB-2 is a panel that has a very low moisture resistance. This solution is only suitable for interior work in dry rooms.

OSB-3 is a more versatile board. Among the characteristics - high resistance to moisture both indoors and outdoors. Also, the plate has a huge margin of safety.

OSB-4 is the most durable and most moisture resistant materials. They are used only to create load-bearing structures in conditions where the level of humidity is especially high.

Which slabs are suitable for the floor?

If you need to make a floor from OSB, then OSB-3 is best suited for these purposes. These plates perfectly withstand the impact of heavy furniture, various equipment and other mechanical loads.

These panels are used to level the floor before laying the final floor covering. If there are only small defects on a rough concrete or wooden base, then the thickness of the sheets in this case should be no more than 10 mm. If there are larger protrusions and recesses on the surface, then it is best to use thicker plates. Their thickness in this case should be from 10 to 15 mm.

If you plan to build a floor on logs, then even thicker sheets should be used - the thickness should be from 15 to 25 mm.

Selection rules

It is worth knowing some selection rules. It is very important who made the sheets. Experts with experience recommend opting for products from Canada or Europe. As for the size, it is considered standard for this material - 2.44x1.22 m.

The main functions of OSB boards

Such panels are used to create an even and most durable base for various types of modern finishing floor coverings. It can be parquet, ceramic tiles, laminate, carpet.

This is ideal for leveling floors. The plywood that was used before does not have such high performance. If there is a choice - plywood or OSB floor, then the latter will be more durable.

Advantages and disadvantages

Among the advantages of such a building material, a sufficiently high density is also distinguished - even a large rat will not be able to damage this base. High resistance to moisture allows the material to be used anywhere - you can lay these sheets in baths, as well as in various unheated rooms.

Laying OSB on the floor does not require special skills - absolutely any home master can do this, which is a serious advantage. To equip the rough base, it is enough to be able to use the usual building level, a hacksaw and a hammer.

OSB is a great opportunity to save money, since the price of these plates is low. One element will be enough to process a serious area. You can also highlight high strength characteristics - even under heavy loads, the floor will not deform.


Installation of OSB on a concrete floor

Imagine such a situation - there is a terribly curved concrete screed. For alignment, you can apply the following scheme. The technology is relevant for any concrete surfaces.

The first step is to clean the work surface as much as possible. To do this, you can use either a vacuum cleaner or a broom. It is necessary to ensure maximum cleanliness, because the sheets will be glued with mounting adhesive. Clean surface - high adhesion.

Then the cleaned base should be covered with a primer. This will help the adhesive adhere better to the concrete surface. In addition, the primer forms a sufficiently dense film on the screed, which will prevent it from dusting during use.

Then they begin to lay out the OSB boards on the floor. If necessary, cut the pieces to the desired size with a jigsaw or circular saw. From the wrong side, parquet glue is applied to the material. It should be chosen only on a rubber basis - it is more effective for solving such a problem. To ensure that the adhesive can be applied as evenly as possible, experienced professionals recommend using a notched trowel.

Additionally, the plate should be fixed with a driven dowel. This is done for a guaranteed and secure hold. It is best to hammer dowels around the perimeter. The interval is 20-30 cm. If the concrete screed is even and the installation is carried out in a dry room, then OSB can only be fixed in the corners, but this is taking into account the fact that high-quality glue is used.

In the process of laying between the sheets, it is necessary to leave expansion joints. Their width should be about 3 mm. A 12 mm seam is also left around the entire perimeter of the room - between the slab and the wall. These are special deformation gaps, which, if necessary, can compensate for the expansion of materials. The OSB floor is almost ready.

In conclusion, it is necessary to thoroughly clean the resulting surface from dust and various debris accumulated there. Expansion joints are filled with mounting foam. The surfaces are then allowed to rest and dry for 4 hours. After that, it remains only to cut off the foam, and you can lay the topcoat.

Installation of OSB on a wooden floor

So, before you do the installation work, you should again prepare the base base. It is very important to pay attention to nails, if any. They must be drowned deep into the board. For this, a regular hammer and a steel bolt are best suited. The diameter of the bolt must be equal to the diameter of the nail. If the floorboard has become unusable during operation, it must be restored with a planer.

After that, you can proceed directly to the installation of OSB. First of all, pre-cut sheets are laid out on the surface. Here, as in the case of installation on concrete, it is important to remember the need for expansion joints. For fixing plates, it is best to use self-tapping screws, the length of which is 4 cm. The interval of fasteners is approximately 20-30 cm. The self-tapping screws are sunk into the plate.

After the installation is completed, it is recommended to grind the joints. This can be done by hand, but if the area of ​​\u200b\u200bthe room is serious, then a grinder will do. If you need maximum effect, then you should arm yourself with a vibrating machine, which is equipped with a grinding grid. It is worth processing the plate with the utmost care - you can easily make recesses on its surface.

Installation of plates is extremely simple. It turns out that all masters understand how to make a floor from OSB. This new building material is worth a try. He is efficient and a pleasure to work with.

OSB laying on concrete floor

OSB boards are a relatively new building material that is widely used in construction and repair work. One way to use it is as a floor covering. Due to its properties, such a coating has high strength and low weight, it is moisture resistant and has a low price, all this explains the growing popularity of this building material. In order for an OSB-covered floor to have a long service life, the fixing of the material must be carried out correctly.


OSB board is an inexpensive, high-quality material for flooring. It is durable, waterproof and lightweight.

Features of choice

Now on the market there is a large selection of OSB, which differ in their properties and characteristics.

In order to make the right choice, you must follow the following recommendations:

  • The highest quality is considered to be the products of Canadian and European manufacturers, it is produced using modern technologies and meets the E1 standard (environmental safety);
  • it is best if OSB-3 is laid (fastened) on the floor;
  • on concrete pavement, it is necessary to use slabs up to 10 mm thick; for wooden pavement, their thickness depends on the distance between the joists.

The size of a standard OSB board is 2440x1220 mm, so the required number of them is calculated based on the location so that a minimum of waste is obtained. Using a circular saw, it is easy to cut the required size; it is not recommended to use an electric jigsaw for this, since it is not always possible to obtain an even cut with it.

OSB laying on concrete floor

If your room has a concrete floor, then fixing OSB as a flooring material is a great solution.

After OSB is laid on the concrete floor, finishing materials can be installed: tiles, linoleum, laminate, parquet board.

The main functions of OSB on a concrete floor:

When calculating the number of slabs, it should be taken into account that the losses when cutting the slab are 7-10%.

  • leveling an imperfect floor surface, which usually has bumps, height differences and other defects;
  • reliable sound insulation, which is ensured by the multilayer structure of the material, which allows you to absorb various noises well;
  • waterproofing and floor insulation. This material has a natural base, high heat-saving characteristics and moisture resistance.

If there are significant irregularities in the concrete pavement, then the OSB-plate is fastened not immediately to the floor, but to wooden blocks that play the role of a lag.

To ensure maximum rigidity and resistance to deformation, it is better to use OSB-plates with a thickness of 8-10 mm, laid in two layers. It is necessary to lay the layers with an offset, they are attached to each other with the help of spiral nails or glue.

If the concrete floor is even, then you can lay the OSB directly on it, in which case one layer will be enough, it is fastened with self-tapping screws or dowels. Although the material is moisture resistant, there is partial absorption of moisture, and it expands slightly. To compensate for possible expansion or contraction, it is necessary to provide expansion gaps between the plates up to 3 mm in size.

Processing material

OSB boards can be used as an independent floor covering, or as a base for laminate, linoleum or parquet.

This coating can also be used independently, for this it is stripped, and then several layers of varnish are applied to it.

If the laying of roll materials is carried out, then it is necessary to ensure a smooth transition at the joints, the plates take a minimum thickness. They try to make gaps from the side of the wall, they are treated with an elastic sealant.

To cover the floor with tiles, the base must be completely fixed, so OSB must be laid especially carefully. The tile is placed on a special adhesive, which ensures a reliable connection of ceramics and wood.

Laying plates under the laminate does not imply special requirements, only at the joints the surface must be perfectly flat.

Benefits of using

  1. Simplicity. No special skills and tools are needed, installation can be done by anyone who has minimal skills in construction work.
  2. Convenience. Plates have a large area, so they cover a large surface. Their size makes it possible to lay logs at a distance of 56 cm from each other, which makes it easy to use modern heaters.
  3. Cheapness. The cost of 1 sq. m of this material compares favorably with similar materials.
  4. Reliability. They perfectly hold fasteners, do not change shape and do not deform, they withstand the load well.
