What is the name of the waterproofing tape for OSB panels. Bathroom in a frame house: how to waterproof the floor and how to insert a drain

Bathroom and toilet in wooden frame house, as you know, require work such as waterproofing and high-quality finishing, which you can do yourself, so as not to overpay for the services of specialists. The walls of such rooms, especially in a wooden frame house, have their own characteristics: in the bathroom you need not only high-quality waterproofing, but also vapor barrier.

For finishing the bathroom in wooden house Ceramic tiles are usually used, although the options vary greatly. The article will consider the question of how best to decorate the walls in the bathroom of a wooden house, as well as how waterproofing and other important work is carried out in the bathroom.

Arrangement of a bathroom in a frame house

The main thing that needs to be taken into account when covering a bathroom or toilet, and the walls in a wooden house in general, is high-quality waterproofing. During the work process, the following points must be taken into account:

The main thing that needs to be ensured in the bathroom is high-quality waterproofing

Waterproofing is carried out using vapor barrier and waterproofing membranes. Sometimes ordinary plastic film can be used, but it must be very dense. At all, plastic film They are usually used for vapor barrier of the walls of a wooden house, and special membranes are purchased for the bathroom. You can also use special mastic, but it is quite expensive. The membrane is fixed to the walls of the bathroom (or if we take the bathroom as a whole) using a special construction stapler;
A metal profile must be installed on the membranes, which will serve as a base (lathing for future wall cladding). The walls are sheathed with sheets of special moisture-resistant plasterboard, and not in one layer, but in two at once. This important point: The humidity level in the bathroom is too high, this can lead to corrosion of the walls, the appearance of fungus, mold and other “troubles”. Therefore, drywall is sheathed in exactly 2 layers;
The first sheets for sheathing are always attached using self-tapping screws, and subsequent ones - using a special adhesive composition. Thanks to this, the screw heads will not need to be coated with a special sealant to avoid rust;
Experts recommend using ordinary PVC panels as decorative cladding for the walls of a bathroom in a wooden house. Using them, you can easily decorate a bathroom with your own hands; this does not require any special skills or abilities. Another 2 good options are using ceramic tiles or moisture-resistant emulsion paint. The only thing that needs to be taken into account when tiling the walls of a bathroom in a wooden house is that the seams between the tiles must be treated with a thick and plastic fugue. This is necessary to prevent moisture from getting into the seams between the tiles, which can lead to erosion of the internal adhesive base. In essence, using a fugue to process tile joints is the same waterproofing, although covering the surface with plasterboard is easier.

PVC panels are considered the best material for covering the walls of a bathroom in a frame house.

Ceiling device

The principle of arranging the ceiling in the bathroom of a wooden house is practically no different from arranging the walls. The ceiling in the bathroom is equipped using the following technology:

Moisture-resistant drywall - perfect option for bathroom ceiling

A vapor barrier membrane is attached to the ceiling beams (sometimes you can hear the term “vapor barrier” - it’s the same thing);
Either slats are attached to the fixed vapor barrier membrane, or, as in the case of wall cladding, the same metal profile;
Using self-tapping screws, sheets of moisture-resistant drywall are secured to the installed metal profile (or slats). If in the case of wall cladding it is recommended to use 2 layers of plasterboard at once, then one is enough for the ceiling. However, the second layer will also not be superfluous, if there is enough drywall - you can make double cladding;
Since the second layer of moisture-resistant plasterboard is most often not mounted on the ceiling, the heads of the metal screws must be covered with a special sealant or mastic to avoid corrosion;
After the screws have been treated with sealant, you can begin covering the ceiling plastic panels. Here you can immediately talk about one nuance: if polyvinyl chloride (PVC) panels were used for wall cladding, then the same material must be used for ceiling cladding. The only exception to this rule is if ceramic tiles were used to decorate the walls. It’s clear what to mount ceramic tiles on the bathroom ceiling will be impossible. In this case you can use dropped ceilings, imitating real ceramic tiles with their pattern and texture. By the way, the lathing described above is just suitable for suspended tiled ceilings; it is impossible to make it any other way, complicating the entire structure;
To decorate walls in the bathroom of frame houses, it is not recommended to use materials that are heavy, from a physical point of view. Frame panel houses have relatively lightweight design. Finishing and waterproofing should not involve the use of heavy materials. For example, if the walls are finished natural stone(or wooden shingles, for example), this will significantly increase the load on the building as a whole.

Self-tapping screws do not need to be treated with sealant if moisture-resistant drywall is laid in 2 layers.

In general, we can conclude that the walls are finished almost exactly the same as the ceiling. A bathroom in a frame house will not be any exception here.

Floor installation

It’s worth mentioning right away that the floor in a frame house, located in the bathroom, will receive the greatest load, especially if the bathroom is not on the first, but on the second floor.

It is for this reason that the waterproofing and finishing of the floor must be done as well as possible. First of all, chipboards are laid on top of the subfloor (their markings of great importance does not have). They have a fairly high density, are durable and resistant to high humidity.

Diagram of a water floor for a bathroom

Placed on chipboards waterproofing film. And it’s already poured onto the film from above cement strainer. It must be said that the floor in panel houses cannot be used without a cement screed, otherwise it will simply rot (this means the bathroom and toilet, and not all rooms at once).

At this stage of work it is necessary to take into account the following nuances:

Linoleum is increasingly being used as flooring for bathrooms in frame houses.

It is permissible not to use a screed if the bathroom is on the second floor. In this case the best option- this is the laying of OSB slabs on the subfloor, on top of which a waterproofing and vapor barrier film is mounted. And on the film you can already mount PVC panels or any other decorative coating. The only thing you should not do is lay tiles on the floor of the second floor. It weighs quite a lot, which will significantly increase the load on the ceiling of a not particularly stable panel frame house;
To heat a bathroom in a frame house, it is recommended to use a “warm floor” system, but not electric, but water. Why should you prefer a water-based “warm floor”? Elementary for the sake of safety, because in a wooden house there should generally be a minimum of electrical communications. Panel house from short circuit it can flare up like a match - and nothing will help later;
When installing a heated floor, you cannot use any insulation, but only one that is made on a foil base. Insulation on a foil base will, as it were, reflect heat, the efficiency of a heated floor in in this case will be significantly increased;
If linoleum is to be laid in the bathroom (the floor is often finished and is done with it), then it should not be cut strictly along the perimeter of the floor, but with some (5-10 centimeters) overlap on the walls. This will avoid water leakage onto the floors of a wooden frame house.

If the bathroom is on the second floor, then it is not recommended to use a cement screed there due to its heavy weight.

The level of planning and arrangement of a bathroom in a frame or log house allows you to judge how comfortable long-term living in such a room is. Often the bathroom and bathroom are the most problem areas wooden building. To protect support beams, joists, and floorboards that are at greatest risk of soaking and rotting, you will need enough effective waterproofing wooden floor in the bathroom. In conditions where the ventilation and heating system capabilities are insufficient, or the room is located on ground floor, with intense moisture coming from the ground, you will need complete waterproofing of the bathroom in a wooden house.

Materials for arranging waterproofing

For each specific building, with its own architecture and layout, specialists select optimal scheme waterproofing a bathroom in a wooden house. Universal recipe does not exist, so to build effective protection several types have been developed insulating materials, each of which has its own advantages and disadvantages:

Bituminous and mastic coating compositions. Waterproofing is carried out by applying a viscous bitumen mastic for all basic elements wooden structures. After drying, a dense elastic layer of bitumen modified with butyl-styrene copolymer is formed;
Deeply impregnated painting materials, most often organic-based. Apply with a spray or brush to the surface of wooden structures of the floor and walls of the building. They give the wood water-repellent properties and at the same time protect it from pathogenic microflora and insects;
Rolled materials based on fiberglass and bitumen. Used only as an intermediate waterproofing on concrete or panel surfaces;
Elastic membranes based on polyurethanes and polyurea. This coating sanitary standards can be used as waterproofing for any interior spaces wooden house.

For your information! In addition to the above, the list for waterproofing can use self-leveling floors based on epoxy or polyurethane based. Acrylic or cement-containing materials are practically not used for waterproofing wooden structures.

Separately, it is worth mentioning several natural waterproofing options: bentonite clay, asphalt and tar mixtures, pressed powder rubber, gum resin, tar and much more, which is often presented by environmental activists as environmentally friendly pure materials. The logic of the sellers of such recipes is extremely simple - for an environmentally friendly wooden house, the waterproofing must also be environmentally friendly.

In fact, all of the listed materials for “natural” floor waterproofing not only pose a certain danger due to the high content of carcinogens, but are also extremely short-lived. If desired, special brands of clay or liquid glass can be used to protect cold stone floors on a soil base, to waterproof a wooden floor in a bathroom from groundwater and moisture, but not for internal protection from exposure to a humid atmosphere.

Technology for waterproofing indoor bathrooms

Usage modern materials allows you to get very high level waterproofing wooden walls and floors even in conditions of almost 100% humidity and in the presence of a water film on the floor covering. Any form of waterproofing is almost never finishing coat, especially if we are talking about a bathroom in a wooden house.

The waterproofing process consists of four stages:

Arrangement of soil insulation;
Repair and restoration of load-bearing structures of wooden floors;
Laying the first layer of waterproofing, covering the bathroom walls with plasterboard or OSB boards;
Casting a concrete screed or self-leveling floor - leveler;
Applying final waterproofing;
Laying ceramic tiles with elastic tile adhesive, sealing joints and baseboards with epoxy grout.

For your information! For bathrooms in a wooden house, the golden rule must be followed - the waterproofing must be double and must protect the floor both from the inside and from the back side.

The exception is bathrooms located on the second floors of wooden houses. In this case, the base of the floor is made of pressed slabs, timber packages or waterproof plasterboard sheets. The final waterproofing is applied to the primed wooden surface walls and floors, after which you can glue the tiles.

The first stage of waterproofing a bathroom with a wooden floor

The favorite location for a bathroom in a log or log house is a corner room on the first floor. In this type of layout in a wooden house it is easier to organize drainage and supply hot water. If the house is built of timber or logs, the room for the bathroom will have to be seriously refurbished. We are talking not only about the fact that a radical reworking of floors and waterproofing will be required, it will be necessary timber walls treat with hydrophobic impregnation like Tikkurila, lay film waterproofing, insulation and lining the walls with plasterboard sheets.

Waterproofing a wooden floor in a bathroom under tiles begins with laying internal insulation and insulating materials. To do this, the floorboards are removed, part of the soil is removed to lay a layer of sand, thick plastic film and a layer of insulation.

If there is a basement under the bathroom, waterproofing the floor can be done using rolled roofing materials. Additional concrete screed and surface treatment with a primer. Traditionally, roofing material is laid on concrete by surfacing, but in a wooden house, molten mastic is usually used to waterproof the floor in the room. All wooden parts of the subfloor, including joists and floor beams, are treated with coating waterproofing or roofing mastic.

After gluing the polystyrene foam insulation, the floor surface is filled with a layer of leveling agent; this is the only way to perfectly level the surface for laying tiles. If desired, you can lay plasterboard or OSB boards. If the bathroom is located on the second or third floors, then the final waterproofing can be applied to a wooden floor that has been cleaned of paint and dirt.

Stage two, applying final waterproofing

The highest quality waterproofing coating providing reliable protection wooden walls and floors, can be obtained using HIDROFLEX sealant paste trademark Litokol or similar polyurea resins. The material is a thick, viscous, odorless mass, non-toxic, and does not require hardeners or polymerizers. The paste can be applied to the prepared surface using a roller or wide spatula.

A correctly selected primer ensures strong adhesion of an elastic waterproofing layer, 1 to 5 mm thick, with concrete, plasterboard, wooden base. Depending on the air temperature, the material dries from 10 to 20 hours.

The concrete floor screed and plasterboard slabs of the bathroom walls are pre-coated with a primer. When choosing a primer brand, you need to be careful, since not all primer mixtures are suitable and interchangeable for waterproofing materials different manufacturers. Already 40 minutes after priming, the paste can be applied. First, elastic tape is glued to the paste at the corners and joints of the walls and the floor. Separately tape all communications and sewer outlets; any ledges and bends of the walls are taped at overlapping joints.

After applying the tapes, you can begin waterproofing the walls and floor of the bathroom. The material is applied at temperatures from 5 to 40 o C; after drying, the elastic coating retains its insulating properties from minus 20 o C to 170 o C. This means that glued to finishing layer tiles in the bathroom unheated dacha will not fall off even in winter.

Mass consumption is 1.3-1.5 kg/m2. The paste is applied in two layers, initially a layer of 1-2 mm is rolled onto the bathroom walls with a roller, then the floor is covered. After the first layer has dried, a second layer of material is applied. After applying two layers, the thickness of the waterproofing is 3-4 mm, which is more than enough for a bathroom and even a mini-pool.

The waterproofing layer of the floor in the bathroom of a frame wooden house remains elastic throughout its entire service life, but it cannot be used as a final covering; when walking, the layer quickly wears out and peels off from the base.

25-30 hours after applying the paste, you can begin gluing ceramic tiles. To lay flooring over a paste surface like HIDROFLEX, you must use elastic tile marks glue, ordinary cement or gypsum mortar will be too hard.

Conclusion

Tile seams and corner joints must be grouted with epoxy resin. The main advantage of using polyurea resins for waterproofing is their high elasticity and strength. A wooden house shrinks and “breathes” within 3-5 years from the moment of construction, so reliable insulation at “playing” joints and seams can only be ensured in this way.

A bathroom in a wooden frame house, as you know, requires work such as waterproofing and high-quality finishing, which you can do yourself, so as not to overpay for the services of specialists. The walls of such rooms, especially in a wooden frame house, have their own characteristics: the bathroom requires not only high-quality waterproofing, but also vapor barrier.

For long term Frame house service needs to pay attention to such an element of the overall design as the vapor barrier of a frame house and its quality. It is important to monitor this already during the construction of the building. Although many still ask the question: is vapor barrier necessary for a frame house?

Vapor barrier from inside the house

Is vapor barrier necessary in a frame house? Well thought out and equipped vapor barrier interior walls frame house is needed for warm and at the same time damp rooms. A frame house generates a large amount of moisture and steam, which must be removed from the structure to maintain optimal humidity, High Quality and the appearance of a frame house with your own hands.

Moisture, in the process of its formation and accumulation, tends to escape through the walls or ceiling. First of all, moist air rises, so a vapor barrier between floors will stop the movement of air and prevent the insulation from getting wet. If the correct vapor barrier of a frame house is not installed, then the humidity in a short time will destroy the construction site, cause quite serious damage to the frame house, and also create an unfavorable microclimate in the house.

Vapor barrier of walls and ceiling of frame house

A vapor barrier from the inside of a house is a barrier designed to protect the surface of walls, floors and ceilings from moisture, therefore ideally protecting them from subsequent wetting.

Correct vapor barrier frame house is an event that is mandatory not only for bathhouses and basements, but also for other premises built or finished using a special technology. Among the main buildings and structures where insulation is needed, the following can be noted:

Buildings that are insulated from the inside, especially if mineral wool or glass wool can be used as insulation. Insulation materials ideally retain overall heat, but do not remove moisture at all. It gradually accumulates in insulation, whereby the base gradually loses its main purpose, and the structure of the insulation is also lost.
Structures with multilayer wall insulation. These are frame houses with special internal insulation, accordingly, protection from steam is simply necessary here.
Frame houses with ventilated modern facades. The windproof membrane in a frame house will play the role of protection from the wind. The installed wind protection seriously doses and softens the directional flows of external air masses.

On a note

The advantage of a well-equipped vapor barrier from inside the house is its ability to normalize heat exchange in the room.

Basic mistakes when installing vapor barriers

If you listen to the opinions of professionals, you can find out what difficulties and mistakes you may encounter when solving such an important issue as vapor barrier for the walls of a frame house. Among the most common shortcomings are:

Construction of external walls

Installation of vapor barrier on the outside of a frame house. Steam will pass through the entire finish and accumulate in the insulation. The vapor barrier layer must be located inside the building, with outside Wind protection will be sufficient;
Installing a poor vapor barrier in a tiled bathroom. In this situation, water and steam penetrate inside through the tile joints. All this automatically leads to a violation of not only the tightness, but also the strength and reliability of fastening the finishing material in the frame house;
Lack of protection from moisture in insulated walls mineral wool and its analogues. The absence of vapor barrier layers is permissible only if the walls are insulated with foam plastic;
Carrying out poor quality work. The processes associated with installing a vapor barrier in a frame house must be carried out as clearly as possible, following the instructions. Even the most minor shortcomings and neglect of the rules will lead to damage.

Frame houses are known for their microclimate that is comfortable for everyone. For its long-term preservation and to seriously increase the service life of the facility, it is worthwhile to competently carry out all work and activities related to construction and subsequent professional finishing frame house.

Materials for vapor barrier in a frame house

Modern manufacturers offer a huge variety vapor barrier materials. Which vapor barrier to choose for a frame house? The most popular of them include the following options:

Reinforced polyethylene. A material that is becoming increasingly rare and popular solely because of its affordable cost. It is used in a process such as vapor barrier of the floor of a frame house. When using it, maximum caution and strict adherence to instructions is required. Otherwise, the frame house can turn into a steam room, that is, humid air will accumulate in the house, making living not very comfortable.
Different options for mastic. These are special mixtures that are applied to the walls of the structure before exterior finishing frame house. Bituminous kukersol mastic, which perfectly allows air to pass through, is popular and is sold at an affordable cost. Any type perfectly collects and retains water, completely preserving the frame of the house in its original form. This is only possible with correct installation vapor barrier of a frame house.

Vapor barrier of frame house partitions

Ruberoid. Ideal for finishing modern frame houses. main feature material is the need for preliminary arrangement wooden sheathing 50 by 50 mm. Modern roofing felt is universal and affordable.
Vapor barrier films. This is a unique option with which you can create high-quality vapor barrier for the walls of a frame house. Vapor barrier films reliably protect the structure and insulation from moisture. All this ensures the most comfortable stay in houses built using frame technology.

All of the listed materials not only provide an excellent level of protection, but are characterized by such positive properties and qualities as the possibility of long-term use, ease of installation, reliability during use and ideal functionality.

Vapor barrier for the walls of a frame house

To install a vapor barrier layer on modern frame objects, you will need to prepare special tools And necessary materials. Proper vapor barrier of a frame house requires a certain sequence of work. The tools that the frame house vapor barrier technology provides include:

Adhesive construction tape with a special double-sided coating is construction tape;
Various measuring instruments and standard scissors;
You need metal staples, a hammer, and nails;
The main vapor barrier material.

Pie frame wall

If the installation of a vapor barrier for a frame house is carried out by adhesion of the main layer, which protects against water and steam, to the main frame using nails, you need to purchase additional slats made of wood or galvanized material. At the same time, it is not necessary to paraisolate the internal walls of a frame house, because there is no temperature difference in the partitions, which means there is no movement of air from hot to cold.

Vapor barrier of the floor in a frame house is simply necessary to avoid getting the mineral insulation wet, which in this case loses its insulating properties. A vapor barrier layer is laid out on the logs, which must be glued at the joints. The counter batten is driven directly onto the top of the joists, and only then the floor covering is installed.

On a note

The installation of a vapor barrier for the walls of a frame house should be carried out after installing the outer layer of wind protection, as well as a layer of insulation.

Sequence of wall vapor barrier

The slats and the frame itself are carefully treated with special disinfection compounds.
The walls are measured.
According to the obtained dimensions, elements of vapor barrier materials are cut out. In this case, an overlap of 10 mm must be taken into account.
The material is being fixed. The fasteners are installed strictly along the perimeter, and slats and construction stapler. It all depends on the base used. Installation must be done from bottom to top. Elements of materials must be positioned strictly horizontally. At the joints you need to use tape, and it is important to overlap the material itself.

The vapor barrier of the walls and interfloor ceilings of the frame house was carried out according to all the rules and after that it is worth taking care of the presence of ventilation. By the way, vapor barrier of the partitions of a frame house is not required, therefore in the internal adjacent rooms the temperature does not differ from each other. But ventilation should pass between the finish and the protection layer. This will help prevent condensation from accumulating in the interior of the overall pie of the structure.

Basalt wool insulation

Vapor barrier of interfloor ceilings

The division of a frame house by interfloor ceilings carries with it the division of the volume of premises into parts. Temperature and humidity may vary in these rooms of a frame house. Thermal air vapor will rise upward, thereby forming condensation on parts of the floors. To protect bearing structures and insulation against moisture, vapor barrier of interfloor ceilings is done.

Interfloor pie

It is very important to make a vapor barrier according to all installation rules. The vapor barrier of interfloor ceilings is overlapped by approximately 100 mm. The joints must be taped with special tape so that even small gaps are not left. Only in this case will the vapor barrier perform its functions.

Proper vapor barrier of a frame house

To achieve optimal results when working with vapor barriers and in the process of vapor barrier work, it is worth using special insulating membranes that at the same time protect from wind. Vapor barrier of a frame house with a membrane on the outside will help release moisture to the outside.

If you do not secure high-quality protection on all sides of the installed insulation, the structure will get wet and lose its basic thermal insulation qualities. If there is no vapor barrier, and the installed insulation layer is tightly covered only with external finishing materials, the cotton insulation will get wet very quickly and, accordingly, will immediately lose its advantageous features.

Experts strongly recommend that builders and owners do not save on purchasing building materials, since this will require material investments over time. Quality materials, as well as proper vapor barrier in a frame house will ensure the most comfortable microclimate in the room and will preserve the general operational characteristics of the building for a long time.

The issue of finishing a bathroom in a frame house is one of the most important. After all, if waterproofing is installed incorrectly or unsuitable building materials are used, the entire structure will become unusable within a year.

Features of finishing a bathroom in a frame house

What you need to know about installing a bathroom in a wooden house:

Only moisture-resistant materials are used - gypsum boards (moisture-resistant plasterboard sheets), tiles, larch or teak.
All wooden elements are treated with antiseptics that protect against rotting.
The insulation in the floor must be “ventilated”.
Finishing wooden elements(lining, board) implies a mandatory ventilation gap between the insulation and the finishing material - not only in the walls, but also on the floor and ceiling.
We must not forget about hydro- and vapor barrier, maximally protecting the insulation from moisture, while ensuring its ventilation.
Given the high humidity, the frame house should be equipped forced ventilation, without which even moisture-resistant drywall can become heavily saturated with moisture over time.

Finishing a bathroom in a frame house

Bathroom waterproofing

Locations susceptible direct action water, it must be properly waterproofed. For this:

OSB boards are laid on the floor on top of the insulation, the joints are filled with sealant;
the insulation in the walls is covered with a vapor barrier;
Places for installing furniture and appliances (bath, shower, sink, etc.) are pre-marked;
spreads onto the floor in places of high humidity roll waterproofing high density with at least 10 cm overhang on the walls (but to be safe, it is better to waterproof the entire floor);
a cement screed is made over the waterproofing ( floor tiles can be placed directly on OSB);
the walls are sheathed with gypsum boards - the gap between the floor and the sheets should be 1-2 cm;
places in the “wet” zone (around the sink and bathtub, in the shower) are treated with coating waterproofing.

DIY wall covering

Wall cladding moisture-resistant plasterboard no different from working with regular plasterboard:

mounted metal carcass from profiles that must be set according to level;
sheets of plasterboard are attached - if the height is insufficient, they are placed staggered, and an additional transverse profile is installed in the place of horizontal seams;
holes for pipes and ventilation are made in pre-marked areas;
between the floor and the drywall you need to leave a gap that is filled elastic sealant– to protect sheets from deformation when the walls of the house “walk”;
the seams are sealed with sickle tape and coated with putty;
Before laying the tiles, the walls are treated with a primer and a means to improve the adhesion of the sheets to the tile adhesive (concrete contact).

Bathroom ceiling installation

When covering a gypsum board ceiling, all holes and joints made in it must be well waterproofed. Can be glued to drywall ceiling tiles, or, if the height allows, make a suspended plastic ceiling.

If you plan to do wooden ceiling, you need to provide a ventilation gap, due to which the wood will evaporate the absorbed moisture. In no case should you make a ceiling completely isolated from the upper rooms - moisture entering the ceiling must be able to evaporate.

A properly designed bathroom will allow you to fully enjoy your country holiday.

Oriented strand board (OSB), when used inside a dry room, does not need any additional protection from moisture. IN worst conditions It turns out that the outer cladding of the house is made of this slab. Over time, it darkens not only from rain, but also from solar ultraviolet radiation. Of course, you can cover the slabs with siding or blockhouse, but this is associated with at great expense. How to treat OSB boards against moisture is a difficult question. Let's try to answer it.

Is additional processing needed?

The moisture resistance of oriented strand boards is characterized by the amount of thickness swelling during the day. According to this parameter, according to the American standard PS 2, European EN-300 and Russian GOST 10632-89, slabs are divided into 4 types (see table).

Let us recall that for external cladding In buildings, only OSB-3 and OSB-4 boards are allowed.

If the constructed structure is to be finished somehow, then during construction the OSB boards lie on the construction site in bundles. Even after one rain, the top few sheets swell almost one and a half times. They will remain like this after drying. The remaining sheets swell at the ends. By the way, to avoid this, the ends of North American products are painted with blood-red impregnation.

There is an opinion among some builders that OSB boards do not require additional processing, since they are already impregnated with resins, waxed, and varnished. Experience shows that after 2-3 years they appearance loses its original freshness, they darken, in some places individual chips bulge, joints protrude sloppily.

Therefore, additional hydrophobic treatment will not be superfluous, especially if it is the facade of a residential building without any cladding. Let's consider how to treat OSB boards from moisture.

1. Transparent impregnations

Most cheap option treatments – water-repellent colorless impregnations. There are no special solutions for OSB. You can use any wood products, with the exception of those prepared on water based. Examples of such compositions:

Antiseptic impregnation for wood Elcon on silicone based. Designed for long-term protection of wooden structures from weathering, rot, and mold. Scope of application: for interior and exterior work. Forms a water-repellent film, non-toxic, allows the wood to “breathe”.
Innovative domestic hydrophobizing composition NEOGARD-Tree-40 based on organosilicon oligomers. Designed to impart water-repellent properties to products made of wood and wood-based materials: plywood, chipboard, fiberboard. Water absorption for chipboard is reduced by 15 - 25 times. Obviously, it is also suitable for OSB. Does not change the natural color of the material, protective properties are stored for at least 5 years.

The most suitable for protecting wood (and OSB) from moisture is the so-called yacht varnish on a urethane-alkyd or alkyd-urethane basis. Some of the popular brands:

Tikkurila UNIKA SUPER (Finland). This brand is a leader in resistance to environmental influences, immunity to ultraviolet radiation and temperature changes.
Marshall protex (Türkiye). Creates a plastic surface film.
Marshall Protex Yat Vernik. It has increased wear and moisture resistance.
PARADE (Russia). Keeps fresh for a long time.
Belinka Yacht (Russia). It has dirt- and water-repellent properties, emphasizing the texture of wood materials.
Antiseptic varnish for wood “Drevolak” on acrylic base with added wax (Russia). Along with antiseptic and antibacterial effects, it successfully protects wood from moisture.

Since OSB is a wood processing product, the same paints and varnishes can be used for them:

Oil paints. Due to the presence of polymer resins in OSB, drying oil-based paints do not always adhere well to the surface being painted. For better adhesion to the base, it is recommended to perform double priming with intermediate putty before painting. Despite this, oil-based coatings under the influence of ultraviolet radiation, temperature changes and precipitation are prone to fading, cracking, and even peeling. We can recommend paint based on natural and modified oil PINOTEX WOOD OIL SPRAY, which has good resistance to external factors.
Alkyd paints are better suited to particle boards because they contain alkyd resin, a product of the chemical reaction of natural oils with acids. Their adhesion is higher compared to oil-based paints, they dry faster and resist atmospheric influences more successfully.
Acrylic compositions, being inexpensive and durable to use, have an optimal balance of qualities and are most in demand for painting wood. In addition, they are available in a wide range of colors.

Attention: pre-treat a small surface in an inconspicuous place to ensure that the material does not swell when exposed to the aqueous acrylic suspension.

In conclusion, we can say that the question: how to treat OSB boards against moisture is difficult to answer unequivocally. Firstly: it depends on whether you want to emphasize the texture of the slab with a transparent solution or, conversely, apply a covering (opaque) coating. Secondly: – on the financial capabilities and aesthetic ideas of the developer.

Good afternoon
We are building a frame house, it is covered with OSB boards, there is a roof - corrugated sheets, it will go into winter in this form. During the summer, after several rains, the OSB delaminated in some places. Is it possible to cover the walls with windproof film for the future ventilated façade for the winter and will it not lose its properties by spring? And what material is better to take: Izospan A, AD? The facade will be a blockhouse.

It is possible to cover an unprotected façade with windproof film, but this will not fully solve the problem of preserving OSB. The fact is that the windproof membrane is designed to withstand the impact of individual drops, which are the result of condensation on the roofing. Good slanting rain, downpour, wet snow is beyond its power, the windproof membrane will “cry” with inside. Undoubtedly, wind protection will reduce the wetting of the OSB, but will not completely eliminate it.

A windproof membrane is a good thing when it is covered with exterior finishing

OSB-3 boards, which will most likely cover the frame of your house, can only be called moisture resistant with a stretch. And then we can talk about their resistance to moisture only in relation to chipboard, fiberboard, OSB-1 and OSB-2, which quickly deteriorate under the influence of water. OSB-3 is not intended for use as an enclosing wall material without subsequent finishing, unlike, for example, cement particle boards(DSP). By the way, in Canada and the USA, where they came to us from frame technologies, for finishing decent houses that should last a long time, they use waterproof plywood, particle boards are the lot of the poorest.

Manufacturers provide such characteristics as the degree of swelling of an oriented strand panel when placed in water for 24 hours. For OSB-3 it is 15%. This is not so little, contrary to the claims of sellers and manufacturers. Of course, on the walls the particle boards are in a vertical position and are only exposed to slanting rain on one side. However, let’s assume that there are showers, sleet, and humidity for a week or two. Low air temperatures and the absence of sun do not allow the walls to dry.

OSB sheets that are not protected from precipitation will get wet and swell. At the same time, they will increase not only in thickness, but also in length and width, albeit not so significantly. As a result, the particle boards, rigidly fixed to the frame, will warp. And it is not a fact that when they dry they will return to their original shape; residual deformations are very likely. In addition, the fastening points will weaken, delamination of the ends may occur (it has already begun for you), and the strength of the gluing will decrease. It is unlikely that particle boards will not suffer critical damage in one season, but their service life will be shortened and the overall stability of the frame will decrease, that’s a fact.

OSB is not a completely waterproof material; it will inevitably deteriorate if exposed to moisture for a long time.

In our opinion, the following options are possible for temporary protection of an unfinished facade from precipitation:

Pull windproof membrane Izospan A (18 RUR/m2) on a vertical sheathing, use a block 4-5 cm thick. The film is quite weak, it is not a fact that it will successfully survive the winter and will not be torn by the winds.
Use Izospan AM (24 rubles/m2) or Izospan AS (35 rubles/m2). Three-layer wind protection is stronger, less permeable to water vapor, but three times more water-resistant, which means it will get wet less. Under the finishing (blockhouse) it could be stretched without lathing, directly over the slabs. But in your case, a ventilated gap and sheathing are needed. It is necessary to ensure free flow of air, the gap should be at the bottom and at the top, under the roof. Option #2 is preferable.
Stretching any cheaper vapor-waterproofing material over the sheathing while maintaining ventilation: roofing felt, reinforced construction vapor barrier, thick polyethylene film for greenhouses (enough for one season). When covering the facade, the waterproofing will have to be removed.

While there is no finishing, polyethylene film, with or without reinforcement, can be used as temporary protection

The right decision would still be to tighten up with finances and finish the exterior finishing by the fall, covering the façade with a blockhouse along a vertical sheathing. In the end it will be cheaper, because they can serve as windbreaks themselves. OSB boards, if they fit neatly. You won't have to spend money on film.

Correct solution“puff pastry” frame wall. If the OSB boards fit well and the insulation is completely closed, they will also serve as wind insulation. There is no need to spend money on an additional membrane.
