MDF panels - excellent decorative finishing material, which is characterized by a high installation speed and the absence of the need for "wet" work at all stages of finishing.

Panels also have their drawbacks (for example, MDF, like any wood, is afraid of water and high humidity, is less resistant to mechanical damage compared to synthetic materials, repairing damage to it is associated with a number of difficulties, etc.).

The fastening of MDF panels depends on the type of base and the desired result. The most common type of fastening is mechanical (on the base, a frame is often equipped with wooden or metal rails, to which MDF panels are attached with nails, self-tapping screws or kleimers) and chemical - using adhesives.

The latter method assumes an even monolithic base, since in this case there is no frame made of profiles or guides.

Glue for MDF - an overview of the best options

The most commonly used adhesives for MDF panels are:

• Liquid Nails . Universal adhesive, which is characterized by high adhesion, resistance to corrosion and moisture. Liquid nails do not react with bases, unlike deep-penetrating adhesives.
• Mounting (or building) foam. It is characterized by various properties such as thermal insulation, sound insulation and high adhesion.
• Universal construction adhesive. A wide group of products, divided into many segments and areas of application. For MDF panels, it is necessary to use only those adhesives that provide adhesion to the base materials (brick, concrete, drywall, tiles, etc.) and wood (MDF consists of fine sawdust).

The most popular adhesive for MDF panels is liquid nails (TYTAN or TITEBOND Multi).

In addition to the economic effect, when choosing an adhesive, it is necessary to take into account the specifics of working with it (time for primary fixation, final drying time, method of application, service life, essential tool and materials, etc.).

Mounting MDF panels on glue - instructions

Consider the technology of mounting MDF using the adhesive compositions indicated above.

Liquid Nails(similar— universal building adhesives). The thickness of the adhesive layer is only 3-5 mm, so the base on which the panels will be glued must be perfectly even. Otherwise, the panels will repeat all the irregularities of the walls or peel off in places of loose fit.

Therefore, before gluing the MDF panels to the wall, it must be leveled.

1. Degrease the surface, remove all contaminants, putty crumbling areas.
2. Before starting work, you need to make sure that there are no irregularities using a building rule, a long level or other tool.
3. The glue is applied in wave-like movements or in another way (for example, in dotted large drops) so that it is evenly distributed over the width and length of the panel. The pitch between the adhesive strips determines the force with which the panel will adhere to the base. That is, for example, when installed in places the greatest load application frequency can be increased. Usually this is 10-15 cm. If the manufacturer specifies a waiting time before gluing, the required pause must be maintained.
4. With the help of a building bubble or laser level, the start panel is set at the desired angle (depending on the intended pattern and installation direction). Most often, vertical installation of panels is used. Start from the corner.
5. The adhesive on the first panel must have enough time to bond to the substrate before installing subsequent panels (the same principle applies to other difficult junctions, such as internal or external corners). The setting time depends on the type of adhesive (see instructions).
6. Thanks to the tongue-and-groove connection, subsequent panels can be mounted without waiting (except for the waiting time before gluing).

Corners (internal or external), as well as horizontal and vertical junctions without a tongue-and-groove connection, are covered with decorative moldings (universal MDF corners). Glue should be applied to the middle of each side of the decorative corner (so that excess glue does not come out when pressed).

The main thing is not to damage the decorative layer of the panels.

Option 2. Mounting foam.

The technology for mounting MDF panels using construction foam is in many ways similar to the technology for mounting using liquid nails or universal glue, with the only difference being that the wall unevenness error using foam can be higher due to a significant increase in foam volume.

The waiting time before gluing the MDF board to the base depends on the requirements of the foam manufacturer.

VIDEO INSTRUCTION

Basic installation errors

For liquid nails:

• Do not overexpose the adhesive before mounting the panel on the base. Otherwise, adhesion will be significantly lower.
• Incorrect application of glue - MDF panels will lose their attractive appearance if adhesive gets on the decorative front surface.
• Wiping off excess adhesive with a highly damp cloth may cause peeling of the decorative coating.

For mounting foam:

• For gluing, use foam with a low shrinkage coefficient and professional tools (high-quality guns for construction foam can regulate its supply smoothly and strictly dosed).
• If you do not wait for the setting time of the first panel, then during the movement of subsequent panels, the foam may collapse and not be fixed on the base.

The question is why it is impossible to glue MDF on liquid nails

Glue "liquid nails" is distinguished by its versatility. It is suitable for mounting a wide variety of building materials. And if “wood” is listed in the list of materials to be glued, then liquid nails are not only possible, but must also be used for gluing MDF panels.

Often, ordinary people can confuse “liquid nails” glue with sealants or silicones (they are applied using the same tool, the tube is very similar to the tube of liquid nails and they can be on the same shelf in the store).

However, sealants for gluing MDF panels are not recommended, since their main purpose is to fix sanitary ware and seal joints.

MDF panels are attached to the wall in two ways - using crates and glue. And if there is a lot of information about the first method, then they rarely talk about the second. One of the most important aspects of working with glue is just the choice adhesive composition, which provides fast and reliable fixation of the plates to the base.

Adhesive Requirements for Panels

Manufacturers of construction chemicals offer customers a huge range of adhesives, which differ not only in price and packaging volume, but also in basic characteristics.

MDF adhesive must meet the following criteria:

1. Have a clearly defined purpose. The label must indicate "universal" or "designed to work with wood-based panels."
2. Provide strong and reliable fastening to the base of mineral (stone, brick, plaster) or organic (chipboard, OSB, DSP) type.
3. Have a high level of adhesion and set quickly. As a rule, manufacturers try to highlight this characteristic in the name with the words “strong”, “superstrong”, “multi” and so on.
4. Demonstrate resistance to moisture, chemicals (salts, acids, alkalis), changes in temperature and humidity.
   

Some buyers have another requirement for glue - transparency. Inexperienced craftsmen are afraid that drops of the adhesive composition may appear at the joints and spoil the overall picture. However, this is an unnecessary precaution. MDF panels have a standard tongue-and-groove connection system, which is convenient for installation using traditional lathing or glue. And at the corners and along the perimeter, the joints are closed with decorative fittings made of MDF, PU or PVC (corners, skirting boards, cornices), so any defects will be hidden behind the overlays.

We add that transparent silicone-based compounds are produced mainly for plumbing work, they are water resistant, economical in consumption and are intended mainly for stone, glass, ceramics, faience, acrylic and other similar materials. It is not recommended to glue panels made of chipboard and fibreboard with them.

Types of adhesive compositions for mounting MDF boards

So, what types of adhesives provide the best fastening of panels to the wall? Conventionally, they can be divided into three groups:

Not too experienced craftsmen for mounting MDF panels on the wall are better off with the Liquid Nails composition. The glue is quite easy to use, the fastening is tear-resistant, it is applied in a thin or thick layer, which makes it possible to even out minor surface defects.

After drying, the assembly composition remains flexible and elastic, which ensures resistance to deformations and vibrations. This is especially important for boards made of wood-based materials, since they tend to change linear dimensions with temperature changes and environmental humidity.

Features of the use of glue for MDF panels

The strongest fastening is achieved on flat, dry, fat-free surfaces. A universal or mounting compound is applied dotted with large drops or zigzag movements, after which you need to wait a while (the duration of the technological break is indicated on the label), attach the panel to the wall, press and tap on the entire surface with a fist or rubber mallet.

For fitting, the master has from 5 to 15 minutes, after which the composition polymerizes and hardens. Excess glue should be removed immediately with a damp cloth or alcohol, and after hardening, they can be cut off with a sharp knife.

Panels can also be glued to the wall using building foam. The technology is a little more complicated. The base must be moistened with a spray gun, apply a thin layer of mounting compound, attach the panel, press it, then tear it off and attach it again. Thoroughly tap the surface and leave to dry completely.

We warn you! Any construction adhesive is a poisonous chemical multicomponent compound. It has a toxic odor and adversely affects health, so when working, ensure an intensive supply of fresh air, constant ventilation, and even better - exhaust ventilation. As soon as signs of poisoning appear (dizziness, nausea, suffocation, etc.), you need to stop working, leave the room and take sorbents before the doctor arrives.

In case of contact with the skin, the adhesive can cause irritation, so the affected area should be washed with plenty of water with a mild detergent and treated with symptomatic agents.

Today, many people sheathe walls with mdf or pvc panels, such sheathing has many advantages: you do not need to pre-cook and level the walls, you can not remove old wallpaper, plaster or paint. Wallboards are a convenient and functional material; finishing with them can be called the simplest, most cost-effective, “clean” and easy method.

Mounting features without brackets and screws

If the surface is dry and free of grease, the panels can be fastened simply with high-quality glue, without dust, drills, screws and staples. But this method is only suitable if the panels are made of lightweight material (plastic, cork). These can be glued without effort and fear with special glue or liquid nails.

The adhesive should be applied pointwise, while the distance between the applied drops should vary from twenty-five to thirty-five centimeters, depending on the weight of the panels and their size. After all the drops of the composition are applied to the plates, you need to wait a few minutes and press them firmly to the surface. Next, the stove must be immediately disconnected, and wait for about one more minute. After that, it needs to be pressed against the wall again, even stronger. This algorithm should be repeated for each next plate.

Criteria for the quality of the composition for the installation of plates

The construction market today offers dozens and even hundreds of types of adhesives with which wall panels are mounted. However, they differ not only in price, but also in their properties and quality. Reviews about them are different. good glue for slabs should:

• become transparent after drying, form a transparent film layer;
• provide high bonding strength;
• be resistant to frost, moisture, temperature changes, alkalis and dilute acids;
• fasten for a long period, quickly seize.

The compositions presented on the construction market and their main characteristics

The installation of wall plates is a responsible matter, therefore, the choice of glue must be approached very seriously. Professionals do not recommend the use of universal means for this purpose. It is wiser to use compositions created specifically for the installation of the material that is available. Universality often negatively affects quality, reduces the strength and reliability of installation.

However, sometimes universal formulations justify themselves, one such example is Kleiberit 636. This synthetic resin adhesive is environmentally friendly, suitable for one-sided application, dries quickly, and is not afraid of moisture.

Clay Moment Crystal is also great not only for mdf and pvc panels, but also for plexiglass plates, various plastics, wood, cork, polyurethane. The product is transparent, waterproof, glues securely, is not afraid of low temperatures.

The composition of "Emfikol 34012A" is colorless, quite viscous, resistant to temperature changes, has good resistance to plasticizers, which are mainly used in PVC.

The MitreFix composition is specially designed for MDF wall panels - it is transparent, waterproof, and provides a fairly reliable and durable installation.

For the installation of plates, you can use not only adhesives, but also liquid nails. Their main advantages are the ability to withstand heavy loads and fasten even materials that are poorly compatible with each other. Reviews of those who used them confirm that they are plastic, it is easy and convenient to work with them.

The choice of glue for mdf and pvc wall panels is a responsible and serious matter. Reasonable advice from professional repairmen will help you make the right choice.

Wall decoration with MDF panels has recently become more and more popular, due to the fact that with the help of them you can quickly tidy up surfaces of a fairly large area. In addition, the installation of the panels will not take much time, since you do not have to wait for the drying of numerous layers, as, for example, in the case of plastering. It also plays into the hands that the surface leveled by them does not require any additional finishing, as is the case with drywall. Another advantage of this material can be called a very affordable price for it.

Do-it-yourself MDF wall mounting panels, which can be carried out even if there is absolutely no experience in this work, are installed quite simply. The main thing is to understand the principle of such cladding, prepare surfaces and pay special attention to accurate calculations and markings.

The abbreviation "MDF" stands for finely dispersed fraction, from which this finishing material is made, including wall panels. The production of MDF consists in the process of dry pressing of a finely dispersed mass from sawdust and shavings, using high temperatures and pressure. To bind the mass, carbamide resins modified with melamine are added to it, which prevents the evaporation of formaldehyde, chemically binding it (formaldehyde emission class - E1). MDF panels are considered an environmentally friendly material, so they are not prohibited from being used for interior decoration premises. The principle of installing panels is similar to installing natural wood, but they have a lower price than the latter.

Installation of MDF wall panels can be carried out in two ways - fixing them to a frame crate or fixing them to the wall surface using an adhesive composition such as "liquid nails". This adhesive is used not only for the installation of wood products and its products, but also for sealing cracks, as it contains sawdust filler. If the filling of defects will be carried out on the remaining visible sections of the wall, then the adhesive mass should be selected by color so that the patched sections do not stand out against the general background.

MDF panels are produced in a wide variety of shades and can have a textured micro-relief pattern that imitates various types of wood or stone, so they can be matched to any interior design. In addition, the panels are easily combined with each other and can be installed vertically or horizontally, depending on what effect the owners want to achieve.

For example, if the ceiling is too high and makes the room uncomfortable, you can install the panels horizontally, using different shades of them alternately. If you need to visually raise the wall, then the panels are installed vertically.

The panels are produced in different lengths and widths, so before choosing the color and shape of the material, you need to think about what effect you want to achieve.

Tools for finishing work

To work comfortably, you need to prepare tools in advance that will speed up the installation of the finishing material, making it as simple as possible. So, from the tools you will need:

• Electric jigsaw or vertical saw.
• Building level and plumb.
• Tape measure, metal ruler and building corner, a simple pencil or marker.
• Electric drill, screwdriver or even a regular screwdriver.
• Construction stapler.
• A hammer.
• Pliers.

The main methods of mounting MDF panels and the materials necessary for this

For the installation of MDF, certain auxiliary materials will be required. Moreover, the purchase of some of them will depend on the choice of mounting method.

Mounting panels on walls can be done in two ways:

• Kleev.
• Wireframe.

Both methods can be used to install panels both in a private house and in an apartment, but for adhesive installation, the main condition must be met - the wall must be perfectly flat. Therefore, if the panels are to be glued to the surface, then it must first be leveled with drywall or plaster-putty method.

To mount the panels on glue, you will need very few auxiliary materials - this is the “liquid nails” composition and fittings.

If you need to level an uneven wall with MDF paneling, while hiding communications behind it or conducting insulation and sound insulation, you will first have to install a frame that will bring the entire future surface into one plane.

The frame for the installation of panels can be made of a wooden beam or a metal profile. It must be said that mounting MDF is easier to carry out on wooden material, since nails or even staples are suitable for this. When mounting panels on a metal profile, metal screws will be needed, and in this case it will not be possible to do without.

When using a frame, a gap inevitably forms between the main wall and the cladding, in which there will be no ventilation air circulation - such conditions are very “attractive” to mold and fungus. Therefore, before installing the crate, it is imperative to audit the wall. If it is wet, then it will need to be dried first, and then treated with special antiseptic compounds. It is still better not to install such a cladding on external thin walls at all, as it will quickly become unusable, and in addition, an unfavorable microclimate will be created in the room over time, which can cause allergic reactions in residents.

To install the cladding panels on the frame, the following materials will be required:

• A wooden beam treated with antiseptic compounds, with a section of 15 × 30, 20 × 30, 20 × 40 or 20 × 50 mm, or a galvanized metal profile - the same as used when installing drywall.
• Insulation material - foamed polyethylene of selected thickness.
• Metal straight hangers that will help to set the guides exactly in one plane.

• Kleimers for fixing panels on the frame.

• Small nails or staples for the stapler.
• Dowels for attaching brackets (suspensions) or direct rails to the wall.
• Wood screws.
• Fitting profile elements - corner and plinth. It should be noted that the design of the corner for MDF panels is convenient in that it can be used to decorate both the external and internal junction of planes, even at different angles.

Preparing the wall surface for cladding with MDF panels

Surface preparation can only be carried out if it is dry. If you find signs of high humidity on it, you must first determine the cause of this phenomenon, and then try to eliminate it. It is impossible to close a damp wall with any panels.

If there are no such obstacles for the installation of MDF panels, then approximately the same preparation of the wall surface is carried out both for the frame system and for gluing. It consists of several operations:

• Wall cleaning.

If the wall is covered with wallpaper, then they must be completely removed, otherwise in a closed space they can become a breeding ground for mold or even insects. High-quality pasted wallpapers, which are difficult to remove, must first be soaked with water or steamed with an iron, and then cleaned with a spatula. Sometimes you have to resort to using special formulations for.

If the wall is plastered and whitewashed, or qualitatively painted water-based paint, then it is not necessary to clean it.

• Wall processing.

In the event that mold spots are present on the wall, then the surface must be “treated” - treated with a special “Anti-mold” composition or with the usual concentrated bleaching agent “Whiteness”. Before processing, it is recommended to clean the surface to the maximum possible depth with a spatula. When the applied composition is absorbed and dried, the wall must be cleaned again with a spatula, and then the treatment should be repeated. It is advisable to clean the area affected by the fungus to the ground, that is, remove the plaster in this place completely and process the main wall itself well.

"Treatment" of the affected areas of the wall with antiseptic compounds

This work should be carried out in compliance with the mandatory safety measures, in a respirator or in a special mask, in order to avoid inhalation of particles of plaster affected by the fungus.

• Closing cracks.

If, after removing the wallpaper or “weak” plaster, cracks are found on the wall, it is recommended to repair them, especially when planning the placement of heat and sound insulating materials under the MDF panels. Cracks must be repaired so that they do not become cold bridges, as well as a place where dampness accumulates, various insects or the same mold can find shelter.

Cracks are first cut in breadth and depth, ...

In order for the putty or plaster mortar to hold well in the gap of the crack, it needs to be slightly expanded and deepened. Then it is cleaned of the remnants of the old plaster and processed with a brush.

… and then densely filled with repair mortar

After the primer has dried, the cracks are sealed with a putty mixture or plaster mortar. In this case, it is necessary to try to ensure that the expanded gap is filled to its full depth.

• Surface primer.

The next step is to prime the entire surface of the walls. Moreover, it is necessary to choose a primer composition containing antiseptic components that will resist the emergence and development of mold, as well as other manifestations harmful to humans.

Mandatory operation - thorough priming of the entire surface of the wall

If it is planned to sheathe wooden walls, then it is recommended to choose a primer, which includes not only antiseptics, but also flame retardants - they will increase the fire resistance of wood.

The primer is applied to the wall with a roller in two to three layers, each of which must dry thoroughly before applying the next.

• Installation of insulating material.

Further, in the event that the panels will be attached to the crate, you can proceed to gluing the insulation material. For this purpose, "penofol", which is glued to a primed surface, is well suited.

The most convenient in work - "penofol" on a self-adhesive basis

Today, you can find self-adhesive "penofol" on sale - it can be very easily fixed on the wall with foil towards the room by removing the protective film backing. If such material was not found, then the usual "penofol" is purchased. It is cut to the height of the wall and glued to the Teploflex glue, applied in an even layer on the wall surface or directly on the insulation. Cloths of "penofol" are pressed against the surface, and with the help of a rubber spatula, air is expelled from under it.

Gluing the joints of adjacent strips of "penofol" with adhesive tape

Sheets of material are mounted end-to-end, and then the glue must be allowed to dry, after which the joints are glued with special foil tape.

Frame structure installation

Carrying out markup

If it is decided to mount MDF panels on the frame, then first you need to decide how the elements will be installed, vertically or horizontally, since the location of the batten guides depends on this factor. For horizontal orientation of the panels, the guide battens are mounted vertically. And vice versa, if the panels are mounted vertically, the frame elements are installed perpendicular to them, horizontally.

The frame is fixed on top of the insulating material. The step between the railing guides is usually chosen within 500÷600 mm from each other, and they must be installed perfectly even.

To find the perfect vertical, you need to use a plumb line with a colored cord, with which straight lines are beaten off on the wall. If the lines are beaten off on a foil surface, then immediately after the beating, each of them is additionally highlighted with a black marker using a ruler.

To determine the horizontal, I resort to the help of a level. The most accurate result will give a laser or water. If there are no such tools, then you can use the usual construction one, expelling the bubble into the middle with special care. Having outlined the currents, they are also connected by lines using a colored cord.

According to the markup, it will be quite easy to correctly fix the guide battens.

When marking, it must be taken into account that the first frame guide is installed at the junction of two surfaces, that is, in the corner of the room or along the floor surface. The first racks will serve as a reference line for the rest of the elements, maintaining the set step.

wooden frame

Wooden bars, despite the marking lines, when installed on the wall, are still checked by the building level for evenness. Then, they are attached to the wall with dowels, for which holes are drilled right through the bars, into which plastic dowels are hammered, after which self-tapping screws are screwed into them (or driven dowel-nails are used). Fasteners are installed at a distance of 350÷400 mm from each other. The length of the dowels or self-tapping screws is chosen so that they go into the thickness of the wall by at least 50 ÷ 60 mm, and the thickness of the crate beam is added to this parameter, given that the screw head is completely recessed into the wood.

It is more difficult to bring all the racks of the crate to the same level if the wall requires alignment with the crate, and the bars themselves will have to be fixed to hangers. In this case, the installation of the frame is carried out in the same way for wooden bars and metal profiles.

Hangers are first fixed to the wall along the marking lines. I fix them on the wall with two dowels, maintaining a step between adjacent ones at 350 ÷ 400 mm from each other. Hanger shelves are bent perpendicular to the wall surface.

Then, two extreme beams on the wall are installed, aligned in level and relative to the wall. They are attached on both sides with self-tapping screws to the shelves of the suspensions. The protruding parts of the shelves are bent back towards the wall.

The installed extreme guides are connected along the outer edge with stretched cords from above and below (or to the right and left - with the horizontal orientation of the frame) - this will become the reference lines (beacons) for the correct installation of the remaining guides in a single plane.

Metal carcass

Metal profiles prepared in size are fixed on the wall according to the same principle as wooden bars, but sometimes liners are made of timber for structural rigidity. To fix the profile, suspensions are necessarily used, even if the wall is perfectly flat and the racks will fit close to it.

If the frame is mounted on a wooden wall, then the hangers for fastening the railing rails are fixed on the wall using wood screws. If installation on a different base of the wall is necessary, then it is best to fix the suspensions with driven dowels-nails.

If the finish is fixed on a wall that has a window or doorway, then appropriate guides must be installed along its edge, on which the lining will first be attached, and subsequently the slopes and platbands.

Installation of MDF panels on the frame

Before starting the installation of the cladding under the frame, all electrical or other cable communications are carried out and fixed, immediately determining the installation locations for sockets and switches, if they are provided on the wall being finished.

Installation begins with the preparation of MDF panels - they need to be cut to the height or length of the wall. The panels are marked with a tape measure and a building corner, the corresponding lines are drawn along which the cut is made using an electric jigsaw, a manual vertical circular or even a conventional hacksaw.

• The first panel must be leveled until the ideal vertical (or horizontal) is reached, otherwise the entire cladding will go further skewed.
• The launch panel is installed with a spike in the corner and fixed to the guides from the side of the corner in two or three places with self-tapping screws. On the opposite side, clamps are inserted into the groove of the panel at the points of its intersection with the railing guides, through which it is finally fixed with nails or staples to wooden frame. Using metal frame fixation of the clamps is carried out with small self-tapping screws with a low head, so that after it is completely screwed in, it does not interfere with subsequent installation.

• To begin with, the spike of each next panel is tightly driven into the groove of the already installed one - this docking edge is already fixed. Mandatory adjustment of the panel according to the level is carried out, since the configuration of this connection allows a certain backlash. After precise exposure, the panel is fixed in the same way with clamps.
• So continue facing to the end of the wall (or to the end of the section, for example, to the doorway). The last panel on the plane is cut in its thickness so that it freely enters the groove, leaving a gap of about 5 mm in the corner. The final fixation of the final panel is carried out with self-tapping screws, right through it. It's okay - the fastener caps at the beginning and at the end of the lined wall will be hidden by decorative corners.

Horizontal installation of panels is carried out in the direction from the floor to the ceiling, and the first canvas must also be perfectly level. Fastening to the crate takes place exactly according to the same principle as with a vertical arrangement.

• In the panel on which the socket or switch is to be installed, a round hole with a diameter corresponding to the size of a standard socket (usually 67 mm) is pre-cut. Drilling is carried out using a drill-crown.

The socket must be fixed securely, and not bend when inserting the plug of electrical appliances. To ensure a hard stop against the wall, it is recommended to additionally fix wooden fragments of suitable thickness on the back side. The front part of the socket and the switch is screwed onto the facing panels or to the corresponding sockets of the socket.

Mounting MDF panels with glue

It is somewhat easier to install MDF panels on glue than on a crate, but using this method, it will not be possible to install insulation.

• To install the first panel, it is necessary to beat off a vertical or horizontal line on the wall, depending on how the installation is planned.

When gluing, the position of the panel must be controlled by level.

• Particular attention should be paid to the choice of glue for working with MDF panels - it must have some special properties:

- The adhesive must remain flexible enough even after its initial hardening, otherwise there is a risk of deformation of the panels. A composition should be selected that will not be affected by humidity and temperature changes.

- The adhesive must have a thick enough consistency to be able to be applied in a thick or thin layer, as appropriate, and evenly distributed over the surface to be glued.

The best option - glue type "liquid nails"

These requirements in terms of the main parameters are precisely met by the composition "Liquid Nails". The primer that the walls are pre-treated with will create good adhesion for the glue on their surface, so the panels will hold securely on it.

• Glue is applied to the back of the MDF lining in dotted or wavy lines. The panel with the glue applied is first firmly pressed against the wall, and then it is torn off and left to “wind” the glue for 3-5 minutes. After that, already for the final fixation, the panel is reinstalled and pressed in the right place, and held on the wall surface for several seconds until the adhesive composition is firmly set.

The adhesive can be applied to the back side of the panels dotted or "snake"

Therefore, in order to speed up the gluing process, the composition is applied immediately to 8 ÷ 10 canvases, which are pressed against the wall and then come off. After smearing, attaching and tearing off the last of the 10 panels, they glue the first, second, and so on, until it comes to the last. When installing canvases, they need to be pressed very well against the wall surface, and for better fixation, you can even grab each of them with self-tapping screws in two places. They are screwed into the groove of the panel, and then the self-tapping screw is closed by the next spike to be installed.

• If the finish is installed horizontally, it is recommended to wait until the glue under the lowest fixed panel dries well - it is necessary to create a reliable support for the rest of the paintings. If there is no time to wait, then the panel can also be attached to the wall with self-tapping screws.
• The last panel to be mounted, if necessary, is reduced in width - it is measured, drawn and the excess part is sawn off with a jigsaw. In the corner, the last canvas is screwed to the crate or wall with a self-tapping screw.
• The final elements of the installation are fittings and skirting boards. The corners are glued at the junctions of two planes to "liquid nails", covering the heads of the self-tapping screws that fasten the panels to the corners of the wall. In the same way, these fittings are fixed around the door and window openings(if special profiles are not used there - platbands or slopes).

They can be mounted in different ways, depending on the chosen design - glued to the same glue, installed on special fasteners or screwed to the wall surface with self-tapping screws. Fixing skirting boards to the floor would be a very serious mistake.

Advantages and disadvantages of wall decoration with MDF panels

Having become acquainted with the technological process of mounting MDF panels, it is possible, summing up, to formulate their main positive and negative qualities.

So to virtues Such a finishing material includes the following qualities:

• Fairly simple installation with the ability to mount the panels both vertically and horizontally.
• A wide variety of colors and textured patterns will allow you to choose a finish for every taste and interior style.
• When mounting MDF panels on a frame crate, you can hide cable communications behind them.
• With the help of panels, even curved walls can be given a respectable look and visual evenness, especially with the right combination of shades.
• Panels, unlike drywall, do not require additional finishing - this saves time, effort, and materials.
• It is easy to take care of the MDF finish, as it is enough to periodically wipe the surface with a damp soft cloth.
• Finishing MDF wall panels have a very affordable price.

disadvantages such panels can be called the following points:

• With this finish, a perfectly smooth surface is not created, since small gaps or depressions almost always form at the joints, depending on the design of the panel.
• When such a cladding is attached to the crate, a gap remains between it and the wall, in which, with insufficient pretreatment or other unfavorable conditions, dampness can accumulate, and microflora that is unsafe for humans can develop. Very often, especially if walls are sheathed in a private house, this empty space becomes a favorable place for nests or rodent paths.
• The coating of the panels is not highly resistant to mechanical stress - it is easy to damage it, for example, by moving pieces of furniture without sufficient care.
• MDF does not belong to moisture-resistant materials in any way, therefore, if the wall behind the sheathing starts to get damp, the panels may swell and the lining will begin to deform.

However, it can be noted that despite the above disadvantages, MDF panels are only gaining popularity and fully compete with. The installation of such a cladding can easily be carried out even by one person without outside help, moreover, who has absolutely no experience in such work, unless, of course, he follows all the technological recommendations.

And in conclusion - a small "visual aid" in the form of a video about the installation of MDF panels:

Video: how to mount MDF panels on walls

MDF panels are a finishing material consisting of wood fibers that are interconnected by organic resins. Due to their cost-effectiveness, they have earned great popularity in repair work. Especially often this material is used for finishing public institutions - offices, shops. A wall or ceiling lined in this way will look aesthetically pleasing and modern. The latest technology has made this product completely safe, which allows it to be used in almost any room. For rooms with high humidity, such as a bathroom, a series of especially durable moisture-resistant panels are available.

MDF panels: advantages and disadvantages

Among the advantages of finishing material:

• relatively low cost;
• variety of colors and textures;
• speed of installation;
• safety;
• high heat and sound insulation;
• practicality.

They have practically no disadvantages. The only significant drawback is the fire hazard. Therefore, manufacturers recommend wiring in special heat-resistant boxes.

Installation can be done in several ways. If you mount the product using a crate, then special preparation of the walls is not required. In addition, communications can be hidden under the crate. You can simply glue the panels to the wall. We will tell you how to glue MDF panels, and how to choose the right adhesive mixture.

MDF panels can also be glued to difficult sections of walls

What glue to choose?

As a rule, the manufacturer of finishing materials gives recommendations on the choice of adhesive. The right glue for MDF panels is a guarantee that the product will stick firmly and will serve for a long time. Universal funds do not always live up to expectations. Although there are universal adhesives that perfectly glue any materials.

Among such generalists, Kleiberit 636 can be distinguished. It is perfectly applied, dries very quickly, and can withstand significant loads. It contains synthetic resins. The German manufacturer gives a guarantee of product safety.

Moment Crystal is also great for gluing wall panels, including MDF. It has high moisture resistance. Not afraid of temperature changes.

Often, so-called liquid nails are used for gluing MDF panels. This is a universal adhesive that can withstand significant breaking loads. With their help, you can even glue materials that do not fit together well. Working with this composition is easy and convenient.

Before you decide which glue to glue the MDF panels with, you need to know what parameters the glue is chosen for. The selection criteria for the adhesive mixture are:

• high bonding strength;
• resistance to temperature changes;
• moisture resistance;
• not toxicity.

Operating procedure

Unlike the method of fastening panels with a crate, gluing them to a wall involves preparatory work. Here is an example algorithm of actions:

1. It is necessary to prepare the surface to be glued: level, remove old wallpaper, prime the wall.
2. Mark the panels with a tape measure, cut to the required dimensions.
3. Apply glue to the wall or panel (depending on the type of adhesive mixture).
4. Press down on the panel being careful not to damage the outer layer.
5. Trim seams if necessary.
6. It is better to fill the seams with sealant. This will prevent moisture from entering and deforming the panels.
7. Leave until completely dry (for a day).

The installation of this finishing material with the gluing method is not a very complicated process. Even a novice master can easily cope with it. However, before proceeding with this simple procedure, we advise you to read the following guide: "How to glue MDF panels: video - lesson":

Wallpapering MDF panels

If MDF panels have served you for many years and have lost their former attractiveness, it is quite possible to update them. To do this, it is not at all necessary to buy and mount this finishing material again. Just cover the old wall with wallpaper.

To the question of whether it is possible to glue wallpaper on an MDF panel, we answer with confidence: it is possible! And not just wallpapers. Self-adhesive and even fabric will do if you have a creative approach to repair. Wallpaper is better to choose textured, foam-based. They will hide the panel joints.

Since the panels are made of wood, they instantly absorb glue. Therefore, wallpapering should occur at a fast pace. And you need to smear both surfaces. First - wallpaper, and at the last moment - panels. It is best to additionally coat the joints with PVA and be sure to roll them with a rubber roller. Otherwise, they may fall apart.

If everything is done correctly, then the panels pasted over with wallpaper will last for many years, and they will look beautiful.
