How to make a gable from OSB (OSB): a step-by-step description of the sheathing process. Sheathing a frame house with osb panels Is it possible to sheathe a frame house with osb

It is desirable that OSB installation specialists carried out on the walls. OSB (oriented strand board) is a material that has gained popularity in the field of construction and home decoration. He is different large quantity advantages that allow it to be used in the exterior decoration of a dwelling, in sheathing internal walls and construction of partitions in the process of redevelopment. In view of the increasing demand for this material, it is worth considering what are the advantages of OSB boards and where they are used, as well as what finishing methods exist for this material.

Advantages and disadvantages of OSB boards

According to builders, wall decoration with OSB boards has a number of advantages:

Compared to other materials sold in sheets, OSB walls are relatively inexpensive.
The method of manufacture assumes resistance to damage, which ensures a minimum of defects during production, transportation and after installation.
They are lightweight, so the installation of plates on the walls does not carry a large load on the supporting structures. Also, due to the lightness, these plates are easy to carry from place to place and install with your own hands.
These plates look attractive on their own. There are several options for additional decorative finishes.
This material is resistant to moisture, decay, fungal infection and is of little interest to insects.
The strength of the structure of the plates does not prevent them from drilling or processing in any other way.

All these properties make the material suitable for external and internal works. However, when choosing, you should pay attention to the reputation of the manufacturer. For the sake of economy, some firms do not comply with technology, so their products turn out to be of poor quality from an environmental point of view. Such boards can emit harmful substances. Any OSB product does not allow moisture and steam to pass through, therefore, in rooms with such a finish, it is worth taking care of decent ventilation.

Areas of use

There are two main ways to work with OSB boards. Firstly, this is the rough cladding of the main wall inside or outside. This option allows you to reduce the number of joints, align the wall and make it more durable. To achieve such results, it is worth considering a number of points:

The fastening of the material is carried out after 30 cm in the intermediate sections and twice as often at the joints.
The outer edges are attached to the wall every 10 cm at a distance of at least 10 cm from the end of the sheet.
For ventilation, gaps are left between them, which are then filled with sealant. This is one of the main ways to provide ventilation for exterior walls.
When finishing a wall of OSB boards, you should take care of protection from the wind and excessive moisture. Taking into account the peculiarities of the material for working outside, it is worth using a superdiffusion membrane; foil polyethylene is useful for finishing inside.

Other nuances in the question of how to sheathe a wall with OSB boards are discussed in the following video:

Secondly, to change the layout of the rooms, you can from the OSB. For this, installation on a wooden or metal profiles. Drywall is fixed in a similar way. The difference between OSB partitions is the resistance of this material to deformation, therefore, such interior elements do not bend under their own weight and are more reliably protected from cracks and other damage.

Since wood is included in the basis of the material in chip fragments, in the manufacture of OSB boards they are covered with a special composition. It includes resins, wax or paraffin. It not only has a bonding effect, but also gives the surface evenness and smoothness, so additional finishing of OSB walls is associated with additional difficulties. Firstly, the outer layer does not differ in adhesive properties. Secondly, some components contain grease and other substances that can seep through exterior finishes and ruin end view so options should be considered. decorative processing material before finishing the OSB walls inside the house.

Paint or varnish finish

Wall painting or varnishing is one of the budget methods decoration of the walls of the rooms. But in order for the layers to lie evenly, and in the future there will be no unpleasant surprises, it is worth considering a number of points.

First you need to inspect all the places where the plates are attached for not fully hammered nails or twisted screws. Such minor flaws can lead to the manifestation rusty spots through the paint. In the case of nails, it is worth using a hammer, because when working with a hammer, not only will there not be a sufficient result, but the wall cladding will also suffer.

If it is planned that the internal walls will be painted, it is worth using acrylic sealant, because on silicone look paint doesn't adhere well enough.

An obligatory stage of work is the surface. It will provide the material with great adhesive properties. In addition, the layer will lie more evenly on the prepared surface and give the appropriate effect. After the first coat of primer, it is necessary to pay attention to the condition of the pile. After such processing, it can rise, and the wall will lose evenness.

To correct this shortcoming, the surface must be treated with sandpaper and another coat of primer applied. After that, you can finish the walls of the room with varnish or paint. Depending on the humidity of the room, you can use the option on alkyd or acrylic. In some cases, water-based paint is also suitable. Some builders recommend acrylic lacquer for walls.

For reliability and aesthetic beauty, it is recommended to apply the coating in 2-3 layers.

Preparing OSB walls for wallpapering

Wallpaper is considered the most popular option for wall decoration, so they are used in rooms with walls finished with OSB boards. Sometimes such a need arises in the process of redevelopment of space. So, before you make a partition, you should make sure that it is in harmony with the rest of the interior.

It can be used if there is a need for the finished wall to become universal for any kind of application. decorative coating. With this type of wall processing, you should pay attention to some features:
Putty is applied to a clean surface. The presence of dust, dirt or traces of other building materials on the wall can adversely affect the quality of the coating, so it is worth washing the wall well before applying the putty composition.
It is worth paying attention that the heads of nails and self-tapping screws are recessed as deep as possible, and upper layer better off with sandpaper. The surface for puttying should be slightly rough.
The joints between the plates are best treated with nitro putty. This will ensure evenness and strength. Alternatively, bodywork putty can be used, since its properties are designed for a moving object. In this regard, the composition has not only lightness, but also great connecting properties, and it does not collapse on the wall for a long time. After completion of the preparatory work, a layer of putty is applied.
After applying the composition, you can proceed to the primer of the surface.

This option is convenient because now you can use any primer over the primer layer. decorative material without regard to the features of OSB plates.

OSB boards are a universal material for wall cladding of a house or finishing rooms inside it. This raw material is used both to strengthen walls and create partitions. It is quite durable, lightweight and resistant to mechanical stress, moisture, fungus and insects.
In order for this coating to last as long as possible, it is worth considering several factors before fixing the OSB. This is especially true for the distance between nails and screws, as well as the location of the joints. The appearance allows the use of OSB boards without any decorative treatment. However, they can be puttied, painted, varnished or prepared for wallpaper. Subject to technology, the result will be smooth walls, which will be the basis for any interior and will delight its owner for many years.

OSB boards are usually used for cladding frame or half-timbered houses. That is why the question of finishing the facade arises. You can choose siding or ceramic cladding, but these options are costly and time-consuming. Staining will be much cheaper. For this, they can be used different means. on the street? This is discussed in the article.
Why do you need to paint tiles?
To understand whether OSB-plates are painted, you should familiarize yourself with their composition and appearance. They are lightweight warm material, which is used in the construction of external structures, internal walls and partitions. The panels may differ in brands, for the outer part dense products are used, the marking of which has the numbers 3 or 4. Since the material is created by pressing wood chips and glue, it is breathable, environmentally friendly, but it is sensitive to atmospheric influences.
And when creating slabs, the sliver is oriented longitudinally in the extreme parts, and across the fibers in the middle. Because of this, strength and heat-insulating indicators of OSB boards are created. Do I need to paint OSB outdoors? The surface of the material is pleasant and warm to the touch, but does not have a very attractive appearance. That is why it needs to be painted.
Another reason for coverage special tool it is considered to protect the material, and hence the house, from destruction, moisture, mold, fungi. Although the products are moisture resistant, the connection areas are vulnerable. Therefore, such facades must be painted. Only before this it is necessary to clean the dust, as well as putty and primer. It is important that there is an exposure between procedures. After puttying, it is necessary to take at least 12 hours to dry. The same period is provided for complete drying of the primer.
Paints
There are many types of paint products on the market today. But not every one of them is suitable for this OSB-slab on the street, it is necessary to determine after studying the properties of the paint and the possibilities. When buying, keep in mind that the panels are 90% wood. Therefore, you need to pay attention to the scope of the paintwork.
Alkyd
How to paint OSB-plate on the street to get a high-quality result? Alkyd paint is great for these purposes. It is perfectly absorbed into the wood, dries quickly due to the water component. But this fact is associated with a lack of funds.
The paint can be stored at a positive temperature, but when hardened, it can withstand frost up to 30 degrees. The disadvantages include low level resistance to fires, alkalis. Alkyd paint is in demand due to:
Absence bad smell, harmful formations.
Quick drying, color retention for a long period.
Excellent hiding power or the ability to obtain flat surface without leaks.
Long service life.
Affordable cost.

Acrylic
How to paint OSB-plate on the street to protect the material from various influences? Suitable having a polymer component, colors and water. The main property required for outdoor service is the ability to create a reliable film.
Akrids have good adhesion and RWS. These properties affect the demand for facade paints. Manufacturers produce mixtures of not only saturated shades, but also with different physical characteristics. The surface of acrylic paint is matte and glossy, transparent and deaf. These mixtures:
Dries quickly, very durable.
Used for processing porous, loose surfaces.
They are water and steam resistant.
Tolerates significant temperature changes.

oily
How to paint OSB-plate on the street so that the material does not deteriorate from various influences? Oil paint is classical. Compared to modern mixtures, it is less in demand, because it has some harmful properties:
High toxicity. During operation, use
Necessary long time for drying, since drying oil becomes the basis for obtaining paints.
Experience is required to apply the product evenly.
Due to the low resistance, it is often necessary to renew the surface.

The advantages include excellent absorbency to the surface, unpretentious storage. thick paint can be diluted with drying oil.
Latex
Which OSB-plates for high-quality home protection? Latex paints suitable for wood are used. To create mixtures, ordinary water is used, acrylic resin, latex polymer liquid substance. It is with her that the usual acrylic enamel becomes a coloring agent.
The basis of the composition is polyvinyl, silicone, other additives to improve performance. Facade paints create to obtain WWS textured, dense.
water emulsion
If you are interested in the better to paint the OSB-plate, then you should pay attention to water-based paint. It is used for finishing external walls. Suitable for renovation of concrete and stone materials which must first be treated with putty and primer. Water emulsions are divided into:
silicate. The basis includes liquid potash glass. Steam resistant paints.
Silicone. They contain silicone resin and fungicidal additives. After drying, they do not let water through and repel dust and dirt.

The better to paint the OSB-plate from the outside, each owner decides on his own. The above tools are perfect for this job.
Coloring
These products are considered special, so their processing is carried out outside the box. The working surface is even, it can be smooth and somewhat rough. Before finishing, the surface should be treated with a special tool.
The edges can be porous, so the pigment is absorbed on them in an increased amount, which will result in uneven color. It will be possible to eliminate the defect with putty for outdoor work. It will remove joints, seams, after which primer treatment is required. The procedure will improve the adhesion of the dye to the OSB panels. It also protects against harmful influences.
If during installation flaws, irregularities appear, then the entire facade must be puttied. At outdoor work paint is applied at least 2 times. The best visual result and a more durable surface is provided by painting in 3-4 layers.
Staining options
How to paint OSB board outside? This work can be done in one of the following ways:
Spray gun or spray gun. This method is effective for smooth durable coating. Coloring with such a device is fast, but increases paint consumption. In addition, the mechanisms are expensive. You can use this method only in calm weather, using a respirator.
Paint brushes. The option is labor intensive and time consuming.
Rollers are used to speed up the process. With this tool, you can quickly and efficiently update large plots. Used for various mixtures.

Details
The inner surfaces of the OSB boards are sprayed. You can also take a roller for painting the ceiling with a water-based emulsion. In hard-to-reach areas, the product is applied with a brush. When applying the first layer, uniformity must be controlled. If you use varnish on water based, then it is necessary to monitor whether the plates deteriorate from moisture. Strokes should be done in one direction.
Before applying the next layer, you need to take breaks to dry the surface. To do this, you need to wait 6-8 hours, the time is determined by the types of paint. Drying should be natural at a stable temperature. Drafts should not be allowed.
The exterior of the house is exposed negative factors, so you need to choose a quality paint for it. Particular attention should be paid to the ends. The sharp edges of the plates should be rounded with a radius of about 4 mm. Then the surface is cleaned of dust and a primer is applied.
When choosing a paint for finishing, you need to pay attention to the aesthetics of transparent varnishes. Many people don't take it well Sun rays. Water-based paints often deform the plates. Organic, alkyd, oily products will be the most suitable. The principle of operation is the same as indoors. But at least 3 layers are applied to the facade.
Nuances
First you should touch the joints of the OSB boards. The processing of these areas will be positive, but not for long, because during the laying of the house, the slabs “play” and the putty cracks and falls out of the seams. This will negatively affect the appearance of the facade. There is another design option for narrow sections - the use of decorative overlays. They close the seams after painting. They are needed as protection and design element.
The painting activity is carried out from the top of the wall so that the paint does not flow onto the drying area. You also need to take into account the weather. Finishing is preferable to do at a positive air temperature.
It should be remembered that the painted facade during operation is considered unpretentious, but care is still needed. Usually the materials are impact resistant. Walls should be washed regularly with detergents unless otherwise advised by the manufacturer. Hard-bristled brushes should not be used as this will damage the finish.
Thus, OSB-plates must be processed. Paint would be an affordable and effective option. The house will be reliably protected from various adverse factors.

OSB (OSB) or OSB-board is an oriented strand board. Due to the strength, which is much higher than that of chipboard, this material is very popular in construction. Sheathing an OSB house with a slab from the outside with your own hands is relatively simple and a budget option.
Scope of OSB and types of plates
In classic chipboard, sawdust is kneaded together with a variety epoxy resin, as a result, they are located randomly in the finished frozen formation. In the OSB-plate, they are guided by vibration not only in layers, but also in the direction of laying, as a result of which the plate receives a much greater fracture strength. In fact, OSB is one of the options for composite materials.

OSB boards differ in the degree of their resistance to high humidity, as well as in strength characteristics: how well they are able to withstand a fracture load. There are 4 grades of OSB: from OSB-1 to OSB-4. Each of these types uses its own types of adhesives, which give the appropriate properties to the finished plate.

OSB is used both for interior decoration and for exterior. Nessesary to use different types boards according to their moisture resistance. OSB boards are durable and practical, they allow you to create complex facades for subsequent painting or plastering from the outside or wallpapering from the inside.
How to properly fix the OSB to the wall
Most often, OSB is used in the construction frame structures where slabs are used as structural material.

To create an outer wall plane, boards should be used that are not lower in quality than OSB-3. Only such material is sufficiently stable for the humidity of the "outboard" air at any time of the year.

When designing such a building, the following features should be considered:
frame racks should be located exactly 2 times more often than maximum length boards to be used. Then the panel will be quite rigid;

forming an external wall plane, you first need to attach a windproof membrane to the frame racks, for the role of which a PVC film is suitable;

to the entire depth of the wall (and this is the thickness wooden racks) in frame-panel houses there is a layer of insulation. So that he does not get damp at the expense internal humidity, before installing the inner wall surface, a vapor barrier membrane (also a polyethylene film) should be attached to the racks of the frame;

after that, OSB can be attached to the frame racks.

Plates should be fastened with self-tapping screws or with nails. It is important that their length is at least 2 times more thickness used OSB (they are usually produced from 9 to 12 mm thick). Of course, for outer surface you need to choose plates thicker than for the inside.

Sheathing the house with OSB slabs from the outside
OSB boards are widely used for lightweight ventilated facades of brick or concrete houses. In this case, the algorithm is:
initially, markings are made on the wall surface where the U-shaped holders will be attached. They are fastened with screws on dowels;

then a layer of insulation is laid on the surface of the wall with glue. It is best to use mineral wool. At the same time, it is initially necessary to calculate the required length of the U-shaped fasteners so that their holders remain 4-5 cm above the surface of the insulation layer. The ends of the holders must pierce the insulation layer;

then we isolate the surface of the insulation with a moisture-proof membrane, for example, a polyethylene film. This is necessary so that the insulation does not dampen, gaining moisture from the surrounding air;

then wooden guide bars are attached to the holders. This is a crate for OSB panels. It turns out that between the membrane and OSB boards a gap is formed for the thickness of the guide. It is necessary to ensure ventilation of the internal space. The guides must be made of completely dried wood so that there is no geometric warping in the future.

further, OSB boards are attached to the guides using nails or self-tapping screws.

Decorative finish options
For internal walls, OSB boards are ideally even, sufficiently strong and absolutely dry surfaces, ready for further puttying, painting, wallpapering. Also, after puttying, relief plaster can be applied. Then inner space will look original. This will require less power.

For the outer surface of the walls, such panels also need to be puttied, and then they can be:
paint;

lay out decorative facade panels;

trim with clapboard or siding.

Painting a house with OSB boards
Coloring is the most inexpensive and practical way final finishing of walls formed from OSB. There are two options here:
painting without pre-priming. In this case it is better to use acrylic paints or polyurethane varnishes. But you need to remember that the surface texture will definitely show through the pigment layer. If this is unacceptable, then additional processing is required.

priming refers to spackling the surface. OSB is a completely dry material that adheres well to adhesive putty. Then comes the stage of painting, after which the house will look elegant and attractive.

Sheathing OSB boards with siding
One of the design options is OSB wall cladding with siding. But there is one subtlety here: the siding panels do not adhere closely to the OSB surface. They specifically have a figured relief in cross section so that the space formed is ventilated.

Therefore, first you need to take care of OSB waterproofing. best choice here will be the processing of OSB boards from the outside with dispersed impregnation, giving any surface water repellency. Possible placement on top of OSB-plates polyethylene film, which will protect the panels from moisture.

OSB - relatively new construction material, which is widely used in construction and repair. Plates have a large number of advantages, thanks to which it is possible to sheathe both internal and external walls. Inexpensive finishing material is also used for the manufacture of interior partitions. Consider what advantages OSB has, where the material is used, what features can be noted.

Features of OSB boards

The OSB panel is made from compressed wood shavings and special resins. Resin products are water repellent. Layers of material are arranged in a perpendicular sequence, this allows you to increase the strength of the plates. OSB surface can be painted, varnished. Plates have a variety of characteristics and when choosing a material, these features are taken into account.

For interior decoration, experts recommend using OSB-3 and OSB-4. These types of products have maximum moisture resistant abilities and are easy to use. final design. Such plates more easily tolerate adverse effects and errors in operation.

When choosing plates, be sure to familiarize yourself with the classiness of the material:

the first class of panels is used in dry places;

the second class of panels is recommended for use as a building or repair material in dry rooms;

the third class of plates is used in rooms with high humidity;

the fourth type of slabs is suitable for structures with high mechanical load and rooms with high humidity.

Advantages and disadvantages of OSB boards

The material is recognized as suitable for finishing work, manufacturing structures for various purposes. Builders are unanimous in their opinion that OSB panels have a number of advantages:

in the end, slab walls will cost an order of magnitude cheaper than after finishing with other materials;

material resistance to mechanical impact allows you to prevent the appearance of defects during transportation, in the process of wall cladding and during operation;

sheets are light in weight, which does not create an additional load on bearing walls, it is easy to carry products;

the external attractiveness of the plates allows you not to finish;

the composition of the products allows you to prevent damage to the material by fungus, mold or insects;

despite the density of the sheets, they are easy to drill, process and install.

The disadvantages of the material is the need for additional ventilation equipment in a room sheathed with OSB. Also, when buying plates, it is necessary to focus on the manufacturer and product reviews: if technology is violated, the material can evaporate toxic substances and be environmentally unsafe.

The use of materials, features of OSB boards

The use of material in construction and decoration is very extensive. The product allows you to hide irregularities and external unattractive moments. The panels are made using a technique that excludes internal voids or defects, which prevents deformation and bending of the sheets directly in the structure.

The use of panels allows:

not only to carry out the finishing of the building to protect it from dampness or for the purpose of warming, but also to refuse additional finishing actions;

use in the construction of frame-panel houses (separate categories of OSB-plates);

construct formwork for the construction of the foundation;

to sheathe buildings from the outside, to finish houses from timber, logs;

build a crate and rafters, as the slabs can withstand the weight of the roof even under heavy loads in the form of precipitation;

lay floors or level even large irregularities.

In general, the use of panels can be divided into the following categories:

for roofing;

for walls;

for the floor.

There are two most popular ways to work with OSB boards: wall cladding from the outside, from the inside and mounting partitions for redevelopment of rooms. When sheathing a room, you can hide all visible defects and align the walls. To do this, follow the recommendations of experts:

at the joints, it is necessary to fasten the material more often than at intermediate sections;

the outer edges should be attached to the wall surface every ten centimeters;

to ensure the flow of air, gaps are left between the plates, which are filled with sealants, this will allow the walls to be ventilated;

when cladding external walls, it is worth considering waterproofing and protection from winds.

How to prepare OSB boards for finishing

There are many materials for wall decoration, but most of them need fine finish: siding, foam or sheathing. Big square sheets makes it possible to make fewer joints when finishing.

Before sheathing, it is necessary to carry out preparatory work, which consists of the following steps:

make the leveling of the surface of the plate - defects and irregularities of the product must be sanded or puttied;

to process the edges - so that the porous edges do not absorb a large amount paintwork material, it is necessary to round the edges;

processing gaps between OSB panels - putty is used for this.

Preparatory work is necessary to extend the life of the material.

A variety of options for finishing surfaces from OSB

Since processed chips of various tree species are used for the manufacture of plates, a special helmet should be chosen for painting, which is intended for finishing wood products.

Instructions are attached to each bank, you must carefully follow it. Particular attention should be paid to the moment of incompatibility of some materials. To avoid unpleasant moments, before painting the entire surface of the plate, it is worth trying the paint on a test fragment. This will show if the materials are compatible.

It is possible to process the surface of OSB boards using the following materials:

Lacquer - it helps to preserve the original appearance of the material, while protecting the plate from negative external influences. Experts recommend applying varnish on a sanded surface or after sanding. Also, masters are advised to abandon water-based varnish, such a tool can deform the surface. To cover the surface of the plates, oil or acrylic varnish is recommended.

Paint for interior work - the same tips work here as for choosing a varnish. Only if there are no strict requirements for surface quality, water-based paint can be used. To prevent the plates from deforming, painting should be carried out simultaneously on all sides of the plate. Acrylic dyes are considered the best for applying to OSB.

Stain - used to emphasize the structure and appearance of OSB. In some cases, the stain is diluted with a solvent or acetone. The latter substance dries quickly and does not lift the pile of the product. A polyurethane primer is applied on top. Materials for dissolving the stain are toxic, so it is necessary to protect the respiratory tract when working with the substance and ventilate the room.

Patina - used for artificial aging of the surface, in order to achieve the desired result, the patina is applied to the primer layer, not to the stain.

Wallpaper - before wallpapering, the OSB paraffin coating should be removed. Delete layer with sandpaper. Then two layers of primer are applied and putty is made. In order to avoid lagging behind the wallpaper from the surface of the plates, experts recommend adding PVA glue to the wallpaper paste.

Very often, the new owner plans to remake the home for himself, and for this he demolishes the old ones. interior partitions. In their place, you need to install new ones. Previously, drywall, LSU, board were actively used for these purposes, but recently they have given way to OSB boards. It is recommended to use sanded panels if you plan to focus on the appearance.

The use of OSB for the roof

OSB of the third and fourth class is often used for roofing. For this, material is taken from flat edge or lock. Experts prefer a lock-type product. There is important points that you should pay attention to before starting work:

The distance between load-bearing beams should not exceed seventy centimeters, no matter for which roof the material is used: sloping or flat.

Since the plates expand slightly, a small gap should be left between them, no more than two millimeters.

Make gaps for each running meter and along the perimeter of each plate, in this case a gap of about three millimeters is recommended.

The OSB boards are attached to the supports with nails, the distance between them is about ten centimeters.

When using the material, it is necessary to pay special attention to the quality of the product and fasteners, due to the fact that the material will be subjected to large loads from adverse weather conditions and precipitation. By themselves roof structures also do not differ in static, so builders are advised to carefully analyze the following points:

when attaching the plates to the logs, you need to use ring or ruff nails;

it is not recommended to use self-tapping screws, they are not strong enough in case of roofing;

in order to correctly select the length of the nails for fixing the plates, it is necessary to add forty to fifty millimeters to the width of the material;

the material is fastened at such main points - along the rafters, the joints of the plates, the ridge cut, along the edges.

How to fix OSB boards indoors

Indoors, the plates are also mounted on the floor or ceiling. The choice of fasteners and fastening pattern is determined by the material of the surface on which the slab will be laid. The laying pattern is considered typical, this allows you to calculate the number of self-tapping screws. According to experts, at laying OSB thirty pieces are required for square meter. It turns out that the plate standard size will require up to a hundred pieces of self-tapping screws. When buying fasteners, give preference to quality products, do not try to buy the one that is cheaper.

For the floor, the material also began to be used more and more often. It is moisture resistant, high thermal insulation properties, ecology. Panels outperform previously popular materials such as plywood or planks. The wear resistance of OSB exceeds the listed building materials. On the concrete screed you can lay one layer of tiles. Between the edges of the panels, a small gap of two to three millimeters should be left for a possible increase in the volume of the product.

The material is easy to lay on their own, even for a person without experience in such work. Panels are easy to cut and install. They can be installed using self-tapping screws, nails or similar fasteners.

How to sheathe OSB walls with do-it-yourself panels

Increasingly, OSB is used for interior decoration. But before you start work, you need to prepare the material, consider what exactly is required.

Of the tools you will need:

perforator;

drill;

screwdriver;

a hammer;

plumb;

roulette;

building level;

marker.

If you still have questions about how OSB walls are sheathed with slabs, roofing, laying on the floor with your own hands, watch the video in which you will find answers to all questions on the rules for working with panels. The main thing is not to violate the technology and use the correct class of plates for a particular case. If you have any questions, then watch the video on this topic:

Today we will talk about how OSB is finished inside and outside the house. Let's figure out what this wood material is, what qualities it has, and why it is used to cover walls and ceilings. You will understand the information received, you will know what and how the masters who were entrusted with finishing will do.

A little about the material

Oriented strand board, abbreviated as OSB or OSB, in the latter case from the English "oriented strand board", a material that has come to replace the same wood products as plywood, MDF and chipboard. From the name itself it becomes clear that the material is based on chips. Their length is within 75-150 mm and width is 15-25 mm. They are located in the plate itself in different directions: in the outer layers longitudinally, in the inner layers transversely. It is this arrangement that gives the material its technical and operational characteristics.

As a raw material for OSB production do not use waste from woodworking enterprises, but the target forest. That is, tree trunks are split into chips and shavings, which are used in production. Hence and high quality products.

The production process itself is based on the pressing of raw materials with the addition of binding components. It is a paraffin-based adhesive, wax, phenol-formaldehyde resin, boric acid, each of which is added to the chips at different stages with thorough mixing. After that, the raw mass is molded, pressed and cut into panels.

OSB classification

Manufacturers today offer four types of OSB boards:

OSB-1 . It cannot be used for heavy loads, it is a purely finishing material with a low moisture resistance coefficient. Therefore, it is recommended to use only in dry rooms. For exterior finish does not apply. The degree of its swelling is 25%.

OSB-2 . material with more high strength, so it can be used as an element load-bearing structure. But moisture resistance is the same as the previous brand. The degree of swelling is 20%.

OSB-3 . This variety is most often used in construction, especially in finishing work for leveling surfaces. It has good strength and moisture resistance characteristics. The degree of swelling is 15%.

OSB-4 . The most expensive material with excellent technical properties. Easily withstands fairly heavy loads and high humidity. The degree of swelling is 12%.

So if you are faced with OSB sheathing, then for sure this is OSB-3 class material.

And one more important point, which concerns comfortable living in a house sheathed with OSB boards. There is such a characteristic - vapor permeability. It shows how much the walls or ceiling can let air through, that is, “breathe”. The higher this indicator, the better, because there is an air exchange of the building.

In this regard, the OSB is not the most the best way. Its vapor permeability is 0.0031 mg/m h Pa. In fact, according to this indicator, it is comparable to linoleum. That is, it practically does not let air through. This means that when choosing an OSB, it is imperative to make good ventilation.

And the last thing that worries consumers of OSB boards is formaldehyde resins used as adhesives. Everyone knows that this type of resin releases free formaldehyde when the temperature rises, which is very dangerous for humans. But in the recipe for oriented strand board it is not very much - a maximum of 3%. For example, in chipboard this glue is up to 14%. Therefore, there is no reason to be afraid. But European manufacturers are already offering boards that use harmless adhesives, some of which have even been replaced with polymers.

Rules for finishing OSB boards

So, having dealt with the material itself, we turn to the main question of the topic of the article - OSB finishing. Available in the form of the plates themselves. To begin with, manufacturers today offer two varieties of them: polished and unpolished. If the walls or ceiling of your house are sheathed with the second variety, then it will have to be prepared - sanded. To do this, use or grinder, or a grinder, on which a grinding wheel is put on.

Now about the finishing methods.

Painting

What can be said about this type of decoration. The simplest in terms of labor intensity, but difficult in that OSB boards have minimal adhesion. The paint applied to it "sticks" with difficulty. And if the operation of the building takes place in adverse conditions, then in a year or two it will peel off. This primarily concerns OSB finishes outside the house.

Of course, if you need to paint the outbuilding from the outside, then there are no problems with this. Because after a couple of years it can be painted again. But when it comes to the main house, then here you will have to solve more serious problems that concern not only decorative design but also long-term service.

Before painting special primers are applied with a high degree adhesion. They are produced in cans and are called that way: primer-paint for OSB. This material is always white color but it can be tinted.

After drying, the surface grind again and then paint, patina or varnish is applied.

Can be used instead of primer special putty, which is again covered with primer-paint on top.

As for staining, OSB boards are used different kinds colors, choosing depending on the purpose of the room, price and quality characteristics. The main task of the manufacturer of works is to increase the adhesion (adhesion) of the surfaces of OSB boards with paint and varnish material.

Facing with ceramic tiles

When was OSB used for exterior finish at home, then it is not necessary to tile its surface. This process is best done indoors. What should be considered in this case.

Firstly, the process of gluing tiles on OSB boards is carried out only with special adhesives based on resins or polymers. Secondly, it is not recommended to use dry mixes for this. It is better to buy glue in spray cans. It contains a semi-liquid adhesive substance in the form of a gel or sealant, similar to liquid nails. This is an adhesive with a reinforced composition and a high degree of adhesion. It is simply applied to ceramic tiles along the perimeter and diagonals. The last one is pressed OSB board holding hands for a short while.

Some craftsmen do not prime the surface of the oriented strand board under the tile, because the adhesive itself has high adhesive properties. And it does not matter to him what material to glue the tiles to. Someone does not risk and applies a primer. Anyway, it won't hurt.

The video shows how ceramic tiles can be glued to OSB:

It should be noted that glue in spray cans is not a cheap pleasure. So there is another option:

on a wall covered with OSB boards, fasten plaster synthetic mesh;

over apply putty;

after drying, carry out tiling.

Wallpapering

Here, what is not recommended is to stick wallpaper on the OSB. I mean right on the surface. As in the case of paint, the plates must be primed. And pre-sand. The primer must be applied in two layers, the first must dry well before being coated with the second.

External finishing of OSB boards

In frame housing construction, this material is now used everywhere. So, every owner of such a house will definitely face a problem. outer cladding. And here, as in the case of interior decoration, there is only one problem - low adhesion and vapor permeability of the material. But from the outside, you can use technologies that greatly simplify the finishing process. The easiest is to carry out external thermal insulation of the house.

For example, the walls of the house are sheathed with polystyrene foam boards, which are attached to the OSB boards with mushroom-shaped self-tapping screws, since the sheathing material allows this to be done without problems. It lends itself well to processing, drilling as well. That is, a through hole is made through the laid polystyrene foam plate with a drill or puncher, which will become a continuation of the hole in the OSB. A mushroom-shaped self-tapping screw is then driven there, which is a fairly strong mount.

As soon as the wall is insulated in this way, on the surface of the heat-insulating layer, plaster mesh. And already plaster or facade putty is applied on top of it. It will turn out a solid and even wall, on which any finishing facade material is laid.

If it is necessary to strengthen the surface of the wall, then the plaster mesh is “planted” on the adhesive composition. After drying, a primer is carried out, and then they move on to facing, for example, with stone or brick. The main task of this technology is a strong fastening of the insulation to the facade of the building. Instead of polystyrene boards you can use glassine or bituminous cardboard if the task is not to carry out external insulation of the house.

The most simple and reliable way house cladding covered with OSB boards - ventilated facade. This is a frame structure, the crate of which is attached to the walls, and already on it the trim elements themselves. So you can install siding, lining, block house, decorative facade panels. The technology is called dry because it does not use solutions and mixtures mixed with water. It has been worked out for a long time, so there are no problems with the construction of the frame and laying the decorative facade material does not occur.

Conclusion on the topic

So, we examined the OSB panels for the exterior of the house (and interior), the technology for decorating them. Now the question arises which one to choose. The question is really difficult. You yourself could see for yourself that this material, so to speak, is capricious in terms of finishing. It takes a lot of time and materials to improve its adhesive properties.

Manufacturers finishing materials also put a lot of effort and money to find technologies for facing OSB boards. And, as you can see, there are suggestions. Some of them showed themselves from a rather favorable side. This is especially true for external insulation, where two tasks are solved simultaneously: thermal insulation and decoration. That is, finishing the house with OSB plates is not only the simplicity of the construction processes, these are certain difficulties in decorating.
