How to make a floor from OSB: features, stacking technology, recommendations and feedback

The OSB board is a modern building material that, by its characteristics, has successfully replaced particleboard and plywood. These oriented chipboards are used in the construction of frame houses, and for insulation. Also, these products are used to arrange roughing. The floor from the OSB is an excellent opportunity for inexpensive and with a minimum of effort to level the concrete screed or the wooden floor.

What is OSB?

Oriented strand board consists of several layers of pressed, and then glued with special water-resistant wood chips. Glue it into three layers. On the outer sides of the chip is placed along the length, inside - perpendicular. This solution gives the new building material special strength.

Types of OSB plates

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

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

OSB-4 is the most durable and waterproof materials. They are used only to create load-bearing structures in environments where the humidity level is particularly high.

Which plates are suitable for the floor?

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

These panels are used to level the floor before laying the finishing floor. If there are only small defects on the rough concrete or wooden base, then the thickness of the sheets in this case should not be more than 10 mm. If on the surface there are more large protrusions and indentations, then it is better to use thicker plates. The thickness of them in this case should be from 10 to 15 mm.

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

Selection rules

It is worth knowing some rules of choice. It is very important who made the sheets. Experts with experience recommend stopping the choice on products from Canada or Europe. As for the size, the standard for this material is considered to be 2.44x1.22 m.

Basic functions of OSB boards

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

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

Advantages and disadvantages

Among the advantages of such a building material is also a fairly high density - even a large rat can not damage this base. High resistance to moisture allows you to apply the material anywhere - you can put these sheets in the baths, as well as in various unheated rooms.

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

OSB is an excellent opportunity to save money, as the price for these slabs is low. One element will be enough to handle a serious area. High strength properties can also be distinguished - even at high loads, the floor will not deform.

Installation of OSB on concrete floor

Imagine this situation - there is an awfully curved concrete screed. You can apply the following scheme for alignment. The technology is relevant for any concrete surfaces.

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

Then the cleaned base should be covered with a primer. This will help the adhesive to bond better with the concrete surface. In addition, the primer forms a sufficiently dense film on the screed, which will not allow it to dust during use.

Then start laying the OSB plates on the floor. If necessary, prun the pieces to the desired size with a jig saw or a circular saw. On the back 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 glue can be applied as evenly as possible, experienced specialists recommend using a notched trowel.

In addition, the slab should be fixed with a dowel. This is done for guaranteed and reliable retention. Scoring dowels is best along the perimeter. The interval is 20-30 cm. If the concrete screed is flat, and the installation is carried out in a dry room, then you can fix the OSB only in the corners, but this is in view of the fact that high-quality glue is used.

In the process of laying between sheets, it is necessary to leave the expansion joints. Their width should be about 3 mm. Along the entire perimeter of the room also leave a seam in 12 mm - between the stove and the wall. These are special deformation gaps, which, if necessary, can compensate for the expansion of materials. Sex from the OSB is almost ready.

In conclusion, it is necessary to thoroughly clean the resulting surface from accumulated dust and various debris. Strain the joints with foam. Then the surfaces are allowed to rest and dry for 4 hours. After that, it remains only to cut the foam, and you can lay the finish coat.

Installation of OSB on the wooden floor

So, before you do the installation work, you should again prepare the base foundation. It is very important to pay attention to the nails, if they are. They need to be drowned deep into the board. For this purpose, an ordinary hammer and steel bolt are best. The diameter of the bolt should be equal to the diameter of the nail. If the floorboard has managed to come into disrepair during operation, it must be restored using a plane.

After this, 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 fastening the slabs, it is best to use self-tapping screws, the length of which is 4 cm. The spacing of the fasteners is approximately 20-30 cm. The self-tapping screws are inserted inside the plate.

After the installation is completed, it is recommended to sand joints. It can be done by hands, but if the area of the room is serious, then a grinding machine will do . If you want the maximum effect, then it is worthwhile armed with a vibrating machine, which is equipped with a grinding net. The slab should be treated with the utmost care - you can easily make excavations on its surface.

Mounting plates is extremely simple. It turns out that all masters understand how to make sex from the OSB. It is worth trying this new building material. It is effective, and it is pleasant to work with.
