How to Cut OSB Plate at Home

Practical advice on the use of OSP (OSB) plates in the repair and construction.

High-quality and reliable OSB boards manufactured by LLC Kalevala LLC are today widely used in manufacturing and construction. Oriented particle boards are made from slivers of coniferous wood and a binder by pressing under the influence of high temperature. over, for the manufacture of one plate, three layers of wood chips are used, in each of which the chips are parallel to each other and perpendicular to the chips of the adjacent layer. This gives the material increased strength.

OSPplates are very strong, reliable, easy to process and operate. They do not contain voids, knots, do not separate, do not deform under the influence of moisture. That is why OSB is used in modern construction and repair, in the decoration of premises, in the production of packaging and furniture.

How to Cut OSB Plate at Home

Below are the recommendations of specialists regarding the use of this material.

1. Choosing the appropriate type of plate

To carry out the work, it is necessary to select the required plate size and the correct type of OSB in accordance with the humidity indicators at the facility and the level of the planned load.

The following modifications of plates: OSP-1. Suitable for indoor use with low humidity and light load. They are general purpose structures. OSP-2. The boards are suitable for indoor use with low humidity. They belong to the category of load bearing structures. OSP-3. Can be used in high humidity. They belong to the category of load bearing structures. This type of plate is the most popular and in demand on the market.

OSP-4. Plates can be used in high humidity. Differ in the increased indicators of resistance to loading.

OSB boards of various thicknesses and formats are also available. The thickness of the plate can be from 9 to 25 mm, size. up to 2800 x 1250 mm. Also, depending on the project, it is possible to choose slabs with an even lateral edge, or with a Groove-edge face that allows them to be joined.

Give preference to products of the right type, depending on where they will be used to increase the efficiency of use of the material.

2. Tips for acclimatization of plates and their protection from water and humidity

Before using OSB at a construction site, it is advisable to withstand them in a particular facility for at least 48 hours. This will allow the material to acclimatize.

In addition, it is important to protect the plates from the harmful effects of water and moisture during storage. And if the material has already been used to decorate the external surfaces of the object, protect it from atmospheric precipitation by covering it with a thick film. Joints of OSP-3 slabs are recommended to be sanded immediately before the final finish.

3. The specifics of material processing

Cutting, milling, drilling OSB can be carried out using a cutting tool or drills made of hard alloys. For cutting it is also permissible to use a manual power tool. It is important to note that before processing the OSB must be fixed, and the speed of the tools should be moderate.

4. Fastening plates and processing gaps

To fix the material, it is recommended to use screws, staples or nails (only not with a smooth shaft). The same connecting elements are suitable as when working with an array of wood, and their length should be at least 50 mm. Begin fastening the OSB (OSB) plate from the middle of the upper part, gradually moving to the sides and down.

As for the gaps, when joining plates with smooth edges, as well as with other building structures, their width should be 3 mm. And if we are talking about plates with milled faces (with the face “Groove-crest”), then between them gaps form by themselves. In addition, when the boards are laid on the floor, a gap of 15 mm is left between them and the wall. And if the material is used for wall cladding, the gap between it and the foundation should be 10 mm.

5. Application of paints and varnishes to the surface of the material

For processing OSB boards, you can use the same varnishes and paints as when working with other types of wood. over, they are used in strict accordance with the instructions.

6. Heat and waterproofing OSB

Mineral wool perfectly demonstrates itself as a heat-insulating material used in conjunction with plates. It is laid on the front side of the building.

If OSB is planned to be installed on the facade, their joints are sealed with a special insulating tape or PUR or PVA glue is added to the groove-comb connection.

As for the junction between the slab and the foundation, it must be waterproofed. For this, bitumen-based formulations are suitable, for example.

7. Basic principles of storage and warehousing of material

The following requirements are imposed on the OSB storage process:

· Ensuring the protection of structures from water (precipitation, discharge from the ground, etc.);

· Ensuring the protection of structures from moisture;

· Ensuring good ventilation.

It is necessary to fold the plates on a flat surface (a board pallet or a wooden grate) flat. Direct contact with the soil should be avoided.

How to cut plywood?

Plywood today is one of the most popular materials for decoration. In this regard, many people have a question, how to cut plywood? To answer it, it is worth familiarizing yourself with some useful information.

Golden rules for cutting plywood

In order to cut plywood as high quality as possible, it is necessary to adhere to a few simple rules. Firstly, you first need to saw across the fibers, and then along. This measure avoids splitting angles and other deformations of the material.

Secondly, depending on the side of the cut, various tools should be used. So, if we are talking about the inside, then the best choice would be a hand or a band saw. If you want to cut the material from the back, then you should use a contour or circular saw.

Thirdly, you need to know that when cutting with a hand circular saw, the speed of revolutions should be maintained at a high level. In this case, the material itself is best served slowly and smoothly, as otherwise there is a high risk of damage to the material.

Fourth, everyone should know that regardless of the type of saw, its teeth should be small. In this case, the risk of defects, in the form of a crease in the sheet, is significantly reduced.

Finally, the fifth rule is to make clear that when cutting you need to stick adhesive tape. This protects the surface of the sheet from chips.

Is it possible to cut using a conventional hacksaw?

The above information can help a person deal with the question of how to cut plywood? Depending on the specific situation, the optimal tool may be different. But what if there is only a hacksaw at hand?


If everything is done correctly, even with the help of such a primitive tool it is possible to evenly cut the material.

So, if you immediately take up the hacksaw and start sawing immediately after marking, the edges will turn out to be terribly uneven. This is due to the characteristics of plywood, however, there is a way out. Before you start sawing, you need to pour the material with boiling water, let it absorb a little, and then remove the excess liquid. This measure allows you to achieve a smooth and smooth cut.

There is another way. before cutting, make cuts with a sharp knife. over, they should be located at a distance of only 1-2 mm from each other (depending on the thickness of the tool). This measure avoids the breakdown of the hacksaw and, as a result, an uneven cut.

Thus, it can be stated that any tool can produce a quality cut. The main thing is to follow simple rules for cutting. However, in order to guarantee the desired result, it is better to purchase professional tools or seek help from specialists.

Do-it-yourself OSB laying on a wooden floor

OSB-boards. a popular building material, consisting of several layers of compressed and glued with resin wood chips, which has become an excellent replacement for fiberboard and particleboard. Gluing of plates is carried out in several layers: to create external chips are laid in length, and for internal. already in width. This arrangement provides OSB boards with increased strength and gives them the ability to hold self-tapping screws (or other fasteners used) firmly.

How to fix the OSB plate to the wall from the outside of the house.

In contrast to fiberboard and particleboard, OSB sheets have a normal thickness.

Several layers of OSB laid on the floor provide excellent sound insulation, increase thermal insulation characteristics, and also soften the impact with the floor when walking. Modern manufacturers have refused to add toxic substances to the composition of the plates, so this building material is completely environmentally friendly.

With the help of OSB, a wooden floor is very often leveled, which has deteriorated over time. OSB boards are easy to install, do not require special skills and tools, so it will not be difficult to fix unevenness of the wood floor. How to do it yourself. read on in the material.

OSB on a wooden floor: how to lay

If the main wooden surface has irregularities, then it is necessary to level the level with the help of special lags, and only then proceed with the laying of OSB sheets. The locking bars must be installed at an even distance from each other, taking into account the joints. In some cases, to eliminate the mobility of wooden boards, the floor will have to be sorted out (install new boards in problem areas). It is worthwhile to remove paint stains and protrusions with a sandpaper from a wooden surface. After that, it will not be superfluous to prime the wooden floor, although this is not necessary.

To ensure maximum reliability, the lower side of the OSB sheets must be waterproofed. If you intend to lay a laminate after OSB boards, then it is worthwhile to make steam insulation on the surface of the boards with a foam film to prevent condensation.

Now we scatter the OSB slab on the floor so that the displacement of the seams of the next row is obtained. Joints in the form of a cross. should not be! Also provided are the gaps between the plates. 3 mm, and around the perimeter of the walls. 12 mm. After that, in the OSB sheets, it is necessary to drill holes, and their diameter should be the same as for wood screws, which in the future will fix the OSB plate to the floor. The holes themselves must be drilled at a distance of about 20-30 cm from each other.

Now you can begin to fix the OSB boards to the wooden floor. The optimum length of the screws is 45 mm or more. If there are no screws, then you can use nails, but this is not the best alternative. To increase strength and other positive characteristics, it is possible to lay the second layer of OSB, but only so that the seams above and below the layers are placed with an offset of 20-30 cm (that is, the placement of the seams of the first and second layer should not coincide).

At the end of the work, all the gaps can be filled with polyurethane foam, the remains of which can be easily cut with a construction knife after drying. That’s the whole process.

Preparing OSB boards for finishing

If the natural pattern of OSB boards suits you, you can varnish it, put the skirting board on it and the floor will be ready, but you can install another type of finish on top of the boards. If nothing is planned to be installed on top of the plates, then in any case it is necessary to cover them with varnish or a special substance that will protect against bark beetles and excessive wear.

When laying laminate over OSB boards, special requirements are not advanced. It is enough to have a surface without sudden changes, and then the laminate, which is equipped with fasteners, will lie on the OSB boards without any problems.

But linoleum and carpet need a perfectly flat field. Even the smallest differences at the joints will let you know about yourself when using, and even outwardly it will not look attractive. If the carpet will be laid elastic, then all cracks and drops will be felt even when walking. In order to eliminate all irregularities, the floor before laying these rolled materials will be best looped to get one level.
