Lathing for PVC panels: types and manufacture. We make a crate for plastic panels Wooden bars for the inner crate of walls with panels

A bathroom is a room with high humidity and frequent temperature changes, therefore, not every material is suitable for finishing it. There are quite a lot of options for decorating a bathroom. One of the cheapest materials is PVC panel. Making a frame for PVC in the bathroom is quite simple, and the material itself is relatively inexpensive.

PVC is made from a synthetic material formed by the chemical mixing of carbon, chlorine and hydrogen, as well as lead. However, lead is present in quality panels in such small quantities that it is not released even when PVC is burned, so this material is safe to use (if it is made according to standards).

It is important to pay attention to the quality of this material, as unscrupulous manufacturers can add phthalates to it in large volumes, which can cause serious harm to health.

Advantages and disadvantages of PVC panels

The ceiling in the bathroom made of PVC panels has all the characteristics necessary for this room. Affordable price and ease of installation makes this material almost ideal for rooms with high humidity.

Of course, low-quality PVC elements have the main disadvantage of their harmful effects on human health and the environment, but if you buy materials for home decoration only in proven places, such problems will not arise.

Disadvantages of PVC panels:

This material is quite fragile, so it is easy to damage during installation.
If the surface on which the PVC frame is attached has irregularities, then part of the space of the room will be hidden under the panels.
Poor-quality materials emit a specific unpleasant odor.

Advantages of PVC panels:

A large selection of shades makes this material suitable for any style of interior.
Due to low sensitivity to high humidity and synthetic origin, PVC panels are resistant to fungal and mold damage.
PVC panels on the ceiling in the bathroom can be installed independently, with a minimum set of tools and knowledge in the construction industry.
The ceiling of such material is easy to repair, as if necessary, one of the parts can be removed without disassembling the entire structure.
Under the plastic panels, you can hide electrical communications and materials used to increase thermal insulation and sound insulation.
PVC panels can be washed with a solution of water and common detergents.
Finishing the ceiling with PVC materials will cost you much less than, for example, installing a stretch or false ceiling.
PVC have a fairly long service life (10-15 years).
Good panels have high fire resistance.

Thanks to all the advantages described above, PVC ceilings enjoy an ever-increasing hype.

Choice of PVC panels

When buying such materials, it is necessary to pay special attention to their quality, since a PVC ceiling assembled from defective components will look sloppy and may also emit substances hazardous to health.

In order not to purchase a fake made in artisanal conditions, you need to ask the seller for a certificate for the goods. You should also inspect the panels for bumps, foreign inclusions and hooks.

The thickness of quality material should be 8-10 mm, the length usually reaches 3 meters, but if necessary, you can order longer specimens.

In any case, it is almost impossible to distinguish high-quality material from low-quality material by eye, so it is best to purchase PVC panels in trusted specialized stores.

Do I need to level the walls before installing the frame?

PVC panels can be installed in two ways: framed and frameless on glue nails. One of the advantages of the frame method is that it hides all surface irregularities of the base surface, so in most cases pre-finishing is not required.

However, if the ceiling has very large irregularities, and fixing the frame at the same level is not possible, you will have to work on such a surface, eliminating especially obvious defects.

PVC elements that are installed on glue nails have less ability to hide ceiling flaws, so the frame method is more popular.

At the stage of preparatory work, it is necessary to get rid of the old finish, if it crumbles, and also treat the ceiling with a special antiseptic, eliminating traces of mold and fungus. All existing cracks and holes must be sealed with cement-based plaster, otherwise the particles of the ceiling may begin to crumble onto the finished plastic structure, which sooner or later will lead to the need to replace some panels.

Tools and materials for installing a frame for PVC panels

The frame for panels on the ceiling in the bathroom can be made of metal or wood. Of course, a metal frame is more suitable for rooms with high humidity, however, a wooden crate can also be installed if, before installing the rails, they are treated with special compounds, for example, drying oil heated in a water bath. It is necessary to process wooden slats after the frame is assembled.

Metal profiles initially have all the properties that are necessary for the long service life of the frame in the bathroom, so they do not require any pre-treatment.

What tools and materials will be required for mounting the frame in addition to profiles:

perforator;
screwdriver;
electric jigsaw or hacksaw;
construction stapler.
building level;
roulette;

Self-assembly of the frame

Even an inexperienced person in the construction trade can assemble a frame for PVC panels, the main thing is to make accurate measurements and accurately calculate the required amount of material.

Assembling the frame:

Using the level, we find the point of the ceiling, which is closest to the floor.
We retreat from the identified point 5 cm down the wall.
At this level, we make a mark around the entire perimeter of the room using a water or laser level and a chop thread.
Using self-tapping screws, we fasten the UD profile guides at the level of these lines, directly to the wall tile. If the crosses that were used when installing the tiles had a width of 2 - 2.5 mm, then the screws can be screwed into the seam between the tiles.
We make transverse markings on the ceiling, with a step between the lines of 40 cm (the markings should run across the direction of the PVC panels).
Now, we attach straight suspensions to the ceiling, bending them into a U-shape, the step between them should be 40 - 50 cm.
We attach wide SD profiles to the suspensions, leading their ends into guides attached to the walls.
We bend the free segments of the suspension to the sides.
If the surface on which the frame is installed is perfectly flat, then the profile can be mounted directly to the ceiling without suspensions.
In places where the location of the lamps is planned, it is necessary to attach additional profiles to the crate.

The frame for the ceiling of PVC panels in the bathroom is installed quite simply and quickly, this is another reason why this design is popular.

Attaching PVC panels to the frame

When the frame is installed on the ceiling, you can proceed to the installation of PVC elements. It is important to follow the sequence of installation of plastic components, and special attention must be paid to closing the gap between the wall and the ceiling. It is possible to matte a ceiling plinth around the perimeter of the room to be finished or a special L-shaped profile for PVC panels.

We attach the PVC panels to the frame:

We install an L-shaped profile for PVC along the perimeter of the bathroom ceiling.
We measure the width of the ceiling across the previously installed profiles and cut in accordance with the measurements of the PVC panels.
From the first panel, you need to remove the chamfer, for a better entry into the groove of the L-shaped profile.
Now we alternately install the remaining PVC panels with the help of self-tapping screws with a press washer or a construction stapler, while making sure that the chamfer of one panel falls into the groove of the other.
During the installation of the panels, we mount the lighting devices, making small holes in the plastic elements at the points of attachment of the lamps using a drill with a special nozzle or a drill and a sharp knife.
We pass wires for lighting devices through the same holes.
Before installing the last panel, we measure the distance from the penultimate element to the starting profile.
We cut the last panel along in accordance with the obtained dimensions.
We fasten the last component of the plastic ceiling to the frame, leading its edge into the starting profile with a narrow spatula or a blunt wide knife.
We cover the gaps between the L-shaped profile and the bathroom wall with white silicone.
The installation of the PVC ceiling is completed, it remains only to wipe its surface from the dust that has accumulated during the installation process.

Installing a PVC panel ceiling in the bathroom is an excellent solution, because this material fits perfectly into rooms with high humidity. The only condition for rooms finished with such material is the obligatory presence of a ventilation system, since the steam formed when the hot water is turned on needs an outlet.

Remember that high-quality installation of the frame is the key to the durability of the structure.

A strong and even crate for plastic panels is a must for such a ceiling or wall finish. There are several options for arranging a reliable frame for PVC panels, and each of the installation methods is quite doable on our own.

PVC plastic panels - characteristics of the finishing material

PVC panels have an impressive range of repair benefits:

Unsurpassed lightness - a square meter of plastic cladding weighs less than 1 kilogram. This allows you to finish with plastic the so-called "weak" walls and ceilings that cannot withstand heavy loads;
Economic cost. Ceiling or wall plastic is an order of magnitude (that is, ten times!) Cheaper than marble, natural stone or high-quality ceramic tiles;
High moisture resistance, including to saturated and red-hot steam. However, it must be taken into account that plastic does not become an obstacle to moisture - it is inert toH 2 O, but only. If necessary, to protect the walls and ceiling from the effects of water, it is impossible to do without preliminary waterproofing;
Labor-intensive alignment of walls and ceiling is not required, this function is performed by a correctly installed crate for PVC panels;
Easy to sanitize and durable plastic trim for decades;
Large selection of colors and sizes. If desired, you can choose such panels that installation costs will be minimal.

A serious drawback of wall and ceiling plastic is its combustibility. This is especially important when renovating toilets and other small rooms. Fire of polyvinyl chloride in a small enclosed space with dangerously toxic combustion products, a person can suffocate in just a few minutes. In addition, wall plastic narrows the size of the room - at least a few centimeters on each side. If the wall is uneven, then the room will decrease even more.

The quality of the installation of plastic panels almost entirely depends on the quality of the crate. An ill-conceived or poorly assembled frame cannot be sheathed with PVC panels - such a design should be completely redone.

Most often, the frame is mounted from ordinary wooden slats, due to the ease of installation and the low cost of wood. More non-trivial options for the crate are also possible, but they are relevant in exceptional cases (see below).

How to make a crate for PVC panels from wooden slats?

For the inner frame of wood, slats with a cross section of 20x20 mm are selected, this is the minimum. It is important that the slats are straight and even, without knots and cracks. It is quite difficult to remove a broken element from the frame and replace it with a new rail. The guide battens will be perpendicular to the panels to be installed, the step between the slats will be no more than 50 cm.

The first step is to assess whether the tree needs antiseptic treatment. As a rule, for sanitary facilities and kitchens, such processing is mandatory, due to the high humidity of such rooms. Even before the installation work begins, the stacks of slats are untied, each is treated with an antiseptic composition using a brush or spray gun. It is advisable to perform such processing in the open air the day before installation - then the tree will dry out qualitatively, and unpleasant vapors will not have to be inhaled diligently.

Impregnated slats are first exposed around the perimeter of the ceiling or wall. The rectangle formed by four slats is the basis of the entire frame. When installing perimeter rails, it is necessary to use a level and a plumb line and measure the “frame structure” several times before mounting. The perimeter will probably not fit snugly against the wall, so additional bars are placed between the slats and the walls (ceiling). Fasteners are made with self-tapping screws in pre-drilled holes, the fastening step is no more than 40 cm.

When the wooden perimeter is created on all the walls, additional guides are mounted to it in increments of 35-45 cm. Here, too, there is a trick - every 50 cm these extended rails must be additionally attached to the walls or ceiling, otherwise the whole structure will sag. Use a heavy metal ruler to check the straightness of the guide rails by passing it between the side perimeter posts.

The finished frame must be strong - even if not at the level railings for lining, but without backlash and any irregularities. After stuffing plastic fittings (ends, corners, turns, etc.) onto the rails, you can once again evaluate the strength of the frame - and, if necessary, strengthen it with additional rails and screws. Then the PVC panels will slide freely onto the mounting place, and the assembly of the plastic dressing of the room itself will take several hours at most.

Lathing for PVC panels made of plastic elements

Plastic crate for plastic panels is somewhat more expensive than a wooden frame and is more sensitive to wall irregularities. Its advantages include perfect immunity to mold and decay, high speed and factory reliability of installation.

Plastic guides are supplied with special clip-on fasteners, whose design is similar to the “father-mother” lock on a laminate or siding. It is not required to treat plastic with antiseptics; you can immediately proceed with the installation of wall or ceiling PVC cladding. But! The side posts of the perimeter will still have to be made of plastic rails, because. the strength of plastic guides for a large area of finishing is not enough.

Without exception, all plastic guides must be strictly perpendicular to the installation of panels. If at least one deviates, the latch clip will not work, and the entire structure will have to be redone. Therefore, a plastic frame is more often used when finishing small walls in baths and steam rooms - when high humidity makes the frame wood an unacceptable material.

Lathing for plastic panels made of metal profiles

This type of crate is used extremely rarely, due to the significant cost of aluminum profiles. How to make a crate for PVC metal panels? Yes, almost the same as a similar design for plasterboard ceilings:

First, along the perimeter of the wall / ceiling, the starting U-shaped profile is installed exactly according to the level;
Further, metal guides with perforations for fastening PVC panels are pushed into it;
Perforated guides are additionally fixed to the ceiling or walls with screws, in increments of 80-90 cm;
Plastic fittings are installed, after which you can proceed with the installation of the panels themselves.

The strength of the metal frame significantly exceeds the wooden or plastic counterparts, and the step between the guides is much larger - 80 cm versus 40 cm. But the price of an aluminum frame can exceed the cost of all panels several times. Therefore, it is used if there are excess fixing profiles after the installation of drywall.

Composite crates have also proven themselves well - from a metal perimeter, to which wooden or plastic slats are attached. The price / quality ratio of such hybrid structures should be recognized as optimal for plastic panels used to decorate walls and ceilings.

This technological element can be made of various materials and built in various ways. Which one to choose depends on your specific needs.

First, let's talk about the material from which the crate is made. As a rule, three different materials are used: wood (or rather, a wooden lath), plastic elements and metal structures (a metal corner or a U-shaped profile, usually made of aluminum).

Wooden crate

Wood is relevant in most cases, it is the basic, universal material for the crate. It fits in most cases, it is inexpensive. What are the disadvantages of wood? There is only one major drawback: rotting. If the room in which you are going to install the panels will contain a damp atmosphere (for example, it is a kitchen or bathroom), then the wood may rot.

To prevent this from happening, the tree must first be treated with a special composition, the so-called antiseptic. Keep in mind that the composition must dry completely before you begin to install the crate: this way you will avoid the unpleasant smell of wet antiseptic composition.

Not every wooden lath is suitable for crate. For this responsible role, you can not use any rubbish that has a place in the stove: a crooked lath, knotty, serrated, cracked. Then the design will last a long time.

plastic crate

When is plastic crate for PVC panels relevant? First of all, it is an alternative to preservative-treated wood for humid atmospheres. Plastic is close in strength to, but is not subject to decay at all. First of all, plastic is used in such super-critical rooms as baths, with their prohibitive humidity and temperature.

Its other advantage is that it is easy to assemble: no fixing materials are needed. Plastic structures for the crate are initially supplied with locking joints for inserting one into the other. At these joints-locks, the structures are held quite firmly.

It should be borne in mind that the necessary condition for the operation of the lock is exactly the right angles between the elements of the crate. If at least one corner is not straight, the lock will not snap into place, and nothing will hold.

From these prefabricated elements - plastic guides - most of the crate is assembled. Side racks are an exception: plastic guides are not suitable for their manufacture. Here you need a plastic rail. The fact is that the connection on the locks built into the plastic guides is not strong enough to make a reliable crate.

Metal crate

The least commonly used metal crate. It is made of aluminum structures of various profiles - corner or U-shaped.

This design is the most durable and most resistant to all external influences; it is used if the sheathing for PVC panels must last for centuries, or if there is a significant excess of an aluminum profile that has nowhere to go (for example, after an unsuccessful calculation of the consumption of materials for). What are the features of such a design?

In installation, it is very similar to a crate for plasterboard ceilings. Screws are usually used as fastening materials, with the help of which the crate is attached to the wall or ceiling. Holes are pre-drilled under these screws in metal structures; also, holes should be drilled for fasteners on which the PVC panels themselves will be installed.

The dimensions of the squares of the crate made of aluminum are much larger than those made of wood or plastic, up to two times. This is due to the fact that the metal is much stronger than both of these materials. Also, a large crate can significantly save expensive structural elements made of light metal.

Finally, there is such an option as a mixed crate. For example, you can combine wood and aluminum; if you have a certain amount of aluminum profile left, “neither this nor that”, then you can make the most key logs of the crate or perimeter from it, and do everything else from wood. Mixed sheathing allows you to combine the best of two designs: in terms of price and quality, it will probably be the best option.

In any case, whatever the manufacturing technology of the crate, the selected material must be mounted in such a way as to prevent any backlash or dangling. If necessary, increase the amount of fasteners.

So, you are planning to make repairs to the premises and have chosen PVC wall panels for decoration. Decorating walls with decorative panels is a simple and economical way to make repairs to your...

The regular need to erect new and different buildings makes it necessary to search for a way by which it will be possible to carry out such a task in a short time. For...

Wall decoration with plastic panels is now very popular. But before deciding to choose this particular option, it is worth studying information about the properties of the material and the technology for its use. At first glance, you can find a lot of information about this finish, but often it is distorted or presented in a form that is inconvenient to read. For this reason, the choice of the source of information should be taken carefully.

Plastic as a material

Wall decoration with plastic panels has its advantages and disadvantages. They must be taken into account when making the final decision. Finishing material has the following advantages:

Absolute harmlessness. Many are afraid of plastic due to the fact that it is not a natural material. Modern technologies that allow the production of harmless products are simpler and cheaper than the old ones. For this reason, it is extremely difficult to find dangerous material even among fakes.
Wall panels for interior decoration are very beautiful. There are many options for colors and textures. In addition, manufacturers are releasing new seamless options that are very different from the usual office panels. You can choose a wood finish, plain, color. Photo printing is also applied to the coating.
Ability to use in tight spaces. Plastic panels for interior decoration are perfect for various niches and other corners of an apartment or house where it is inconvenient to work with other materials.
Panels are easily mounted together with ventilation grilles, sockets. On any color, these elements look natural and are not striking.
Plastic is perfect for finishing the bathroom and other wet areas. Wall and ceiling decoration is durable, does not require complex maintenance, can be operated at low temperatures (for example, on an uninsulated balcony).

PVC panels look pretty good for their price

The disadvantages include the following negative points:

Flammability. The material is difficult to set on fire, but when exposed to fire, it supports combustion and releases a large amount of gases dangerous to humans.
Panels do not breathe. They completely block the movement of air through the walls, which is necessary to ensure normal ventilation. Due to this property, the type of finish is not recommended for use in the bedroom and children's room.
Insects can settle in the voids of the panels. This problem is especially relevant for the southern regions.
The need to use a special tool for cutting and certain skills during installation.
Do-it-yourself wall decoration with PVC panels requires careful preparation of the base.

Finishing can look very non-trivial!

Having considered all the advantages and disadvantages of the material, you should calmly make an informed decision about the possibility of using this type of finish.

What tools will be required

It is worth preparing for working with PVC panels. First of all, you need to find a special tool:

Circular Saw. If it is not possible to find it, you can use a jigsaw. The file or disk should be fine-toothed (“clean cut”). It is preferable to use a saw. The jigsaw file is highly flexible, so the cut can turn out to be wavy.
Jigsaw chute with 45 and 90 degree angles.
Construction stapler when sheathing on a wooden crate.
Rubber mallet with hook rule. The same tool is used for installing laminate. Needed to "pull out" jammed panels. By doing this by hand, you can easily damage the panel or crate.
Plaster spatula, which is used to bend the finishing profile when installing the last plank. Spatula length 80-120 cm.

Also, when performing work, you will need:

pencil and tape measure;
building level;
square;
fasteners (self-tapping screws, dowel-nails, clamps);
screwdriver;
perforator;
sealant;
antiseptic.

Installation of plastic panels for wall decoration

Plastic can perfectly replace wooden decorative elements and other finishes. But it must be fixed in strict accordance with the technology. Decorative wall panels will help make your home cozy and beautiful.

Finishing the walls in the bathroom and other rooms, as well as the ceiling with plastic panels, is carried out in the following order:

ground preparation;
markup;
crate device;
installation of start and finish profiles;
installation of all other strips;
facing of slopes;
fixing skirting boards.

Foundation preparation

Work with plastic begins with the removal of the old coating. In order for the finish coat to have an attractive appearance without distortions and other troubles, you will need to carefully close up all the cracks in the walls and ceilings, and eliminate irregularities.

Cleaning the surface of the walls is necessary to prevent the appearance of dust, fungus and mold

markup

Before finishing the room, it is necessary to determine the location of the racks of the frame. Finishing with plastic panels of ceilings and walls provides for marking in the following order:

Mark a point at a distance of 1-2 cm from the level of the floor or walls. Through this point draw a line around the perimeter. For marking accuracy, a building level is used.
When marking the walls, the same line must be drawn under the ceiling.
From the bottom line with a step of 40-50 cm, parallel lines are drawn to the entire height.

This marking is suitable for mounting panels vertically. The cladding is always fixed perpendicular to the frame, therefore, if necessary, arrange the cladding elements horizontally, perform vertical markings.

Horizontal and vertical mounting types

Lathing device

Most often, wood is used as a crate for panels for interior wall decoration. In this case, the slats must be pre-treated with an antiseptic composition to protect against destruction. Holes for fasteners with a distance of 50 cm are made along the marking lines using a puncher. The frame rails are fixed to the wall. If it is necessary to lay wiring under the finish, this must be taken into account at this stage:

provide fasteners for wires;
check that they do not protrude beyond the plane of the crate.

Be sure to check the horizontality of the crate

When using a metal C-profile as a crate, you need to additionally buy elements for fasteners. They are usually sold as a set. The metal is fixed to the base with self-tapping screws in dowels. All work must be carried out in accordance with the manufacturer's instructions.

To increase the thermal insulation or sound insulation of the walls, special mats can be laid between the frame rails. They are fixed depending on the type of material used. For different types, it can be used both for mounting on dowels and for adhesive composition.

Lamella fastening

The first plastic bar needs to be fixed in the most illuminated and noticeable corner. Most often, this becomes the one that is located opposite the entrance to the room. Take measurements using a tape measure. The panel is cut to the required length with a special tool (usually a circular saw).

One edge of the plank is inserted into a special side molding. This element is designed to ensure mutual fastening of panels that are located on opposite sides of the corner. An element with a molding is applied to the corner and fixed to the crate from the back.

Next, you need to connect the first panel to the second. For this, the tongue-and-groove system is again used. The joint is pressed tightly and the bar is fixed to a wooden or metal frame. All subsequent elements are mounted using the same technology. To guarantee maximum tightness of the joints, it is recommended to grease the side edges with silicone before installing the panel. When installing the last part, it is worth checking whether it fits in width. If necessary, the element is trimmed in width. The last panel is not fixed to the crate. It must be snapped onto the finishing element. If necessary, all joints are treated with silicone (sealant).

Installation of panels on the frame using clamps and clips

To complete the installation, you need to install accessories. Such elements include skirting boards and their plugs, corner elements. The latter are bought together with the panels and glow over them.

Panel fittings will give your finish a neat finished look.

To make holes for switches and sockets, use a sharp knife. They cut holes of the required size.

Mounting panels with glue

If necessary, finishing elements can be fixed directly to the wall without the use of crates. In this case, increased requirements are imposed on the base. It will take more time to prepare it, since the surface must be perfectly flat.

Before starting work, they acquire a special glue. It is allowed to use liquid nails for installation. It is important to check the composition of the substance in the store. It should not contain solvents that destroy plastic elements.

The work is performed in the following order:

cleaning the base from the old lining;
treatment with antibacterial putty or a layer of primer, which contains components that can protect against mold and mildew;
drying the base;
preparation of the adhesive composition in strict accordance with the manufacturer's instructions on the package;
the choice of a working tool is carried out depending on the consistency of the glue: roller, brush, spatula;
work begins with corner elements;
glue is applied at a time to a small area (equal to about 1-panels) so that it does not have time to dry;
a corner piece is fixed, to which an ordinary element is mounted with the help of grooves;
the panels are pressed against the wall with their hands for a short time, during which the adhesive solution has time to grab;
mount all other panels;
install decorative elements, coat the seams with silicone sealant.

In addition to mounting on glue and on the crate, there are several more methods that are used by professional workers. But they are not widely used. In conclusion, a few general tips can be given:

The panels are recommended for finishing balconies, loggias, bathrooms, hallways and living rooms. For bedrooms and nurseries, you should pay attention to more breathable materials.
It is best to use seamless plastic in rooms with air conditioning or a forced ventilation system.
In the bedroom for adults, it is permissible to use material for individual sections of the walls.
It is unacceptable to use items in the kitchen. In this case, grease and other substances will settle on the surface of the panels, which will become an excellent breeding ground for bacteria.

How to make a crate for PVC panels in the bathroom? Do I need a crate for mounting plastic panels?

When planning repairs in the bathroom, it is necessary to select materials for finishing that are highly durable and resistant to operating conditions at high humidity.

One of them is PVC panels, which are characterized by low cost, aesthetic appearance and ease of installation.

Problems of frameless installation of PVC panels

Installation of PVC panels is possible in two ways: frame and frameless.

At first glance, the frameless method is simple, but during the installation work it turns out to be the opposite.

This is primarily due to the need to ensure a smooth and durable surface of the walls.

Not every bathroom has perfectly smooth walls after renovation. With significant irregularities, the consumption of leveling compounds will increase significantly.

In addition, the alignment process itself will take a layman a lot of time and will require the use of a laser level. If even minimal errors are made, all inaccuracies will be visible on the decorative surface.

Another problem of direct contact of PVC panels with the wall is the impossibility of laying the cable with unhindered access to it in case of non-standard or emergency situations.

The option with the installation of the crate will reduce the cost of leveling the walls, make it possible to hide all the necessary communications, and also lay several insulating layers.

The presence of a rigid structure will allow the installation of a partition between two bathrooms and ensure sufficient structural strength.

Choice of cladding material

The material for the crate should be chosen based on financial capabilities and the preferred service life.

wooden bars

For the crate, straight and smooth slats are suitable, without various defects with a cross section of 20x20 mm. During installation, there will be no particular difficulties, since they are easily processed and can be fixed in any suitable way.

Wood must be dried in a natural way so that the structure does not lead.

To prevent mold or fungus from forming on the surface, you need to apply several protective layers: antiseptic and varnish or paint.

The service life of the structure, provided that the optimum level of humidity is maintained, will be up to 5 years.

Metallic profile

Provides high structural strength. All elements have standard sizes and therefore there is no need to adjust them.

Besides:

Profiles have high protection against moisture and elevated temperatures, so their service life can be up to 15 years, provided that during installation there was no damage to the outer layer.
Products have a significantly lower weight than when using wood, so they do not create critical loads on walls and ceilings during their installation.

The cost of installing metal profiles will be minimal, so this option is optimal in terms of price / quality.

Plastic elements

Such material for the crate appeared relatively recently, so it is not widely used.

Plastic structures have maximum protection:

from moisture;
from mold;
from pests.

They are extremely easy to install due to clip-on connections. No additional treatments, adjustments or protective layers are required.

Plastic slats are plastic, so they can take the shape of a wall.

However, this does not mean that the installed PVC panels will be installed crooked or skewed, since the advantage of the clips is the impossibility of operation with such installation errors.

Plastic rails can be installed on any type of ceilings and walls. The disadvantages include their high cost and relatively low strength.

Calculation of the material and the choice of the design of the crate

Before carrying out work, you need to calculate the required amount of material. Therefore, the first step is to accurately measure the length and width of the surfaces for finishing.

Based on the measured data, a sketch or drawing is created, from which the cost estimate will be determined and the best option in choosing the batten material will be found.

The frequency of the location of the guides should be within 30-40 cm and be selected based on their uniform location along the plane.

When planning, it must be taken into account that if it is required to make PVC sheathing with panels in a horizontal direction, then the crate must be laid vertically, and if vertically, then vice versa.

The number of fastenings of the crate to the wall is 30-60 cm, depending on the chosen method of fixing and the strength of the walls or ceilings.

Preparatory work

Preparatory work consists in assessing the evenness of the walls and the need for their partial alignment.

Usually, in panel or brick houses, significant wall defects are quite common, caused by non-compliance with construction standards or caused by a long service life of the facility without major repairs.

Significant irregularities are most commonly found near bathroom floor or ceiling corners.

You can estimate the size of irregularities using a laser level. If the size of the irregularities is more than 5 mm, then it is recommended to perform leveling by grinding the existing layer or applying a new one.

If there is no laser level, then you can use the folk method: attach a flashlight to several points at the junction of the walls, mark the places of shading, and then align them.

There is no need to achieve perfect evenness - it is enough to get deviations of no more than 1-2 mm per linear meter of a wall or ceiling.

To save money, you can not align the walls.

In this case:

You will need to determine the most convex point on the surface using a laser level and take it as the zero level.
Then make marks of the leveled plane on the perpendicular walls with a marker.
During installation, you will have to mount the guides at the zero level.
It is convenient to do this only when installing a metal crate, since elongated steel fastening brackets are provided for it, which are enough to bend to certain sizes.

The disadvantage of this method is the loss of usable bathroom space.

Installation work

Installation of the crate in the bathroom for the installation of PVC panels begins with the markup. They take two guides and fix them in parallel on two opposite sides of the wall or ceiling.

Then, at the points of attachment of structural elements, threads are pulled, which will be a reference point for the zero level. If the walls are even, then this stage consists in the usual drawing of lines with a marker on the plane at the locations of the guides.

In the presence of high humidity in the bathroom and in order to prevent the appearance of dampness on the walls, it is recommended to lay a vapor barrier layer before marking.

How to proceed further:

A metal or wooden crate is installed, starting with mounting the rails from left to right along the wall or from the opposite corner from the door.
The first bar is placed in a strictly horizontal or vertical position, depending on the type of construction, and then fixed on both sides with dowels or self-tapping screws.
After that, additional fasteners are screwed with an interval of 30-40 cm.
Then take the next guide and mount in the same way. This method establishes all the elements of the crate.

The plastic crate is attached to a special adhesive tape or to an adhesive base. In this case, it is necessary to pre-clean the surface of the wall or ceiling from dirt and grease in order to improve adhesion.

For the convenience of carrying out further work on the arrangement of the bathroom, it is recommended when installing the crate be guided by the following rules:

When carrying out a major renovation of the bathroom, you should create a design and interior project. This will make it possible to provide in advance places for fastening additional interior elements without damaging the decorative PVC panels.
The panels are recommended to be placed strictly in a vertical or horizontal position, so that during installation there is no need to adjust them. When choosing one of the directions for laying panels, do not forget that if you make a horizontal placement, the room visually expands and shortens, and if it is vertical, the ceiling height increases.
To install a lighting system at the planning stage, you need to consider the method and scheme for laying hidden electrical wiring. This will ensure reliable electrical protection and not occupy the usable area of the walls for laying boxes with cables.

The installation of plastic metal or wooden elements of the crate for the bathroom for PVC paneling is a fairly simple process that even a non-specialist can handle.

The main thing is to carry out competent calculations and perform preparatory work. Only with this approach during installation there will be no additional difficulties or problems.
