Is it possible to stick wallpaper on MDF? Wallpaper and decorative panels: finishing and combination in the interior. Geometric combination of finishes

Sometimes, due to the characteristics of the premises, during interior decoration we are forced to resort to the use of several types of finishing materials at once. This method allows you to focus on the obvious advantages of the interior, hiding some of the disadvantages of the room itself or each of the finishing materials. Today, one of the most popular options is a combination of wallpaper and various panels - PVC, MDF, SIP and others. While some are only wondering whether it is possible to glue wallpaper on MDF panels, this method of decorating the interior has already proven itself to be effective in both living rooms and non-residential premises. Let's look at this technology in detail.

How to glue wallpaper on panels?

Construction hypermarkets and finishing materials markets sell a wide range of various types decorative panels for finishing walls and ceilings. We will look at the most popular of them, and also answer the question of whether it is possible to glue wallpaper on MDF and similar materials, and how to do it correctly.

PVC wallpaper and trim

Before you start gluing wallpaper in combination with plastic panels, you need to prepare work surface. Your flow of action should look something like this:

Prepare all the necessary tools and materials - primer for plastic panels, solvent, sandpaper or its equivalent with fine grain.
Sand the glossy surface, making it matte where the panel and wallpaper are attached (for better fixation).
Wipe off all fine dust from the surface of the plastic with a slightly damp cloth and wait completely dry.
Apply a primer that is designed specifically for use on plastic trim.
Treat the surface using special tools with an adhesive primer with the addition of a solvent.

Surface preparation is complete. Now you can start gluing wallpaper, no longer wondering whether it is possible to glue wallpaper on plastic panels, because the answer will be positive: yes, it is possible!

Panels made from wood products

In many large construction stores You can easily purchase analogues of decorative panels from woodworking products. They contain ground wood coniferous species. Small particles are bonded together by pressing. high temperature. Thus, MDF panels do not contain “chemicals” such as resin, glue, etc.

Important! Such panels have good heat and sound insulation properties. As a rule, the width of the MDF panel is 58-60 cm, height - 2.5-2.7 m, thickness - 12 mm. Today you can find on sale wide choice MDF panels of various colors and textures.

Modern production technology creates light and porous boards with good density, which makes it possible to glue wallpaper or even textiles onto similar MDF panels. In this case, any type of wallpaper can be used - paper, vinyl, fiberglass and others. That is, to the question whether it is possible to glue wallpaper on MDF, the answer will be positive, but under a mandatory condition: the panels must be well primed with a special compound so that they do not absorb all the glue.

Liquid wallpaper and SIP panels

A popular type of finishing today is a combination of SIP panels and liquid wallpaper.

Installation of the latter on decorative surfaces, including on a SIP panel - quite simple. However, when using liquid wallpaper in a room with high humidity, it should be additionally treated protective layer special coating.

In general, liquid wallpaper is a good option for interior decoration premises. They have excellent performance characteristics, while having a beautiful appearance thanks to the various inclusions included in the composition. Plus - they are quite easy to install, which even a non-professional can handle, following the instructions.

How to combine materials correctly?

Exists huge amount options for combining various finishing materials. Let's look at the features of using the most popular of them in finishing small apartments or country houses.

Geometric combination of finishes

The design of surfaces with alternating vertical or horizontal inserts of wallpaper and panels is suitable for absolutely any room design:

Fragments can be highlighted by alternating different panels and wallpapers for decoration. The most suitable for this option would be thick vinyl or non-woven wallpaper with relief.
Stripes can be alternated different colors- contrasting or plain shades.
The width of the strips that is optimal for the room should be selected based on the height of the ceiling or the length of the wall.
The decoration of the corridor and other rooms can clearly demarcate each other with borders, friezes, and moldings. Such material will not only disguise the joints, but also serve as a decorative element.

Application of inserts:

The first step is to prepare the walls, prime them with a special solution.
The surface is then wallpapered or paneled.
Next, the necessary finishing is installed in pre-designated areas.

Important! Inserts can be strips of wallpaper or sections of panels different forms and size. This method involves decorating some elements with borders or moldings.

Wallpaper inserts over a large area

This method is necessary for finishing different semantic areas in one room, that is, for zoning it. For example:

When dividing a children's room into a bedroom, play area and study area, you can install panels of soothing colors in the area of the bed and desk, and apply linens for the play area bright colors.
For a living room, a good option is to use contrasting panels or wallpaper to highlight a niche with a TV installed.
In the bedroom, the most commonly used option is to highlight the head of the bed. The best option- a combination of wallpaper and panels that have different shades the same color.

Application of flaps

Such original method combining finishes is suitable for creating an unusual room design. Here everything is limited only by the imagination of the master. Wallpaper is cut into pieces various forms and sizes. Then they are glued to the surface in any order, creating beautiful patterns.

Important! Do not forget about pre-treatment of the panels before applying wallpaper to them.

Non-standard room geometry - what to do?

If the room has a complex configuration with the presence of ledges and niches, do not be upset and consider this fact a disadvantage of the house. It is easy to make such a design an advantage, and you don’t have to spend a lot on such changes. To do this you just need to select everything non-standard areas from the common space of the house by combining different finishing materials. Having beaten in this way complex shape room, your eyes will see a completely different view of it.

The main problem of large and tall rooms is the need to fill the wall space with some content. Additional furniture or interior items are not always suitable for this, as they eat up space. The best way out in this situation is to combine finishes.

This way you will disguise the shortcomings of the room and turn them into advantages. The most popular way to do this type of finishing yourself is to combine panels and wallpaper.

Combination methods

The most common is vertical and horizontal alternation of wallpaper panels.

Horizontal or vertical combination of finishes

Wall decoration with alternating vertical or horizontal stripes of wallpaper and panels is suitable for any room design.

Areas can be highlighted by alternating plastic, wood, cork strips and various types. Thick vinyl or non-woven fabrics with relief are best suited for this.
You can alternate stripes of both contrasting and solid colors.
The instructions say optimal width strips must be selected based on the height of the ceiling or the length of the wall.
Often, when finishing a corridor with panels and wallpaper or another room, they are separated from each other by borders, friezes, and moldings. They not only mask joints, but also serve as decorative elements.

Application of inserts

First the walls are prepared.
Then they are covered with wallpaper or covered with panels.
Next, a compatible finish is installed on the pre-left areas.
Inserts can be sections of panels or strips of various shapes and sizes.
This design involves decorating the inserted elements with borders, thin slats or moldings.

Wallpaper inserts on large volumes

This method is optimal for finishing different semantic areas of one room, i.e. its zoning.

For example, a children's room is divided into sleeping, play and study areas. Install panels near the bed and desktop instead of wallpaper (calm colors), and cover the play area with canvases of bright colors. Such a semantic load will allow the child to concentrate where necessary or show his dynamics and emotionality.
In the living room good option– highlight a wall or a niche with a TV using contrasting panels or wallpaper.
In the sleeping area, it is best to highlight the head of the bed. The best way to do this - combine canvases and wall planks that have different tones the same color.

Application of flaps

Choose this original method of combining coatings if you want to create unusual design premises.
Here your imagination is not limited, you can cut and glue pieces of canvas onto panels different sizes, colors, textures and shapes.
At the same time, you can organize the flaps into some patterns or glue them abstractly and chaotically.

Pay attention!
We should not forget, before gluing the wallpaper onto plastic panels, that the planks must be pre-treated and primed.
Only then will the materials be combined with each other.

Emphasis on projections, niches and structures

When your home has a complex configuration (protrusions, niches, crossbars, etc.), you should not consider it a disadvantage of the house. Such a design can be made advantageous. Moreover, the cost of such a change will be small.

You can play with the complex shape of the room by highlighting non-standard areas from its total volume. So the room will appear in a completely different form. You can, for example, cover the walls with planks, and cover the niches with panels that contrast in color.

Wallpaper sticker on the panel

When combining finishes, the question often arises: is it possible to glue wallpaper onto MDF panels or plastic, wooden, etc. analogues. Let's figure it out.

Analogues from woodworking products

On at the moment you can buy it in many large hardware stores decorative panels from woodworking products, for example Finnish ISOTEX.

They consist of ground coniferous wood. The particles of the material are held together by pressing it at high temperatures. In other words, it does not contain “chemicals” - resins, glue, etc.
Such panels have excellent heat and sound insulation qualities.
Their width is 58 or 60 cm, height 2.7 or 2.55 m, thickness - 12 mm.
Currently, a wide range of panels of various colors and textures are produced..

Pay attention!
Innovative production technology makes it possible to produce lightweight, porous slabs that at the same time have good density.
This makes it possible to glue wallpaper or textiles to such acoustic panels.
Moreover, panels can be used in any variety - paper, vinyl, fiberglass, etc.

How to glue panels to vinyl planks

Is it possible to glue wallpaper on PVC panels? Yes, it's quite possible. But the base must first be sanded and primed.

You will need an abrasive pad (Scotch Brite), plastic primer, white spirit and an adhesive primer.

First, matt the plastic covering with Scotch Brite..
Next, remove any dust that has formed..
Then apply two.
Dilute the adhesive primer with a solvent and coat the panels with it using.
When the soil dries, the question of whether it is possible to glue wallpaper on plastic panels will be resolved. Do it with confidence.

Liquid wallpaper and SIP panels

Liquid wallpaper is a fairly popular type of finishing. They have excellent decorative and soundproofing qualities.
They mask small and medium-sized wall irregularities well.
Another important advantage of the coating is that it can stretch without changing the structure. This property is indispensable if finishing is carried out in a new house that has not undergone final shrinkage.

Applying liquid wallpaper to SIP panels is very convenient, because... The walls are absolutely smooth. If you use them in the kitchen or bathroom, then coat the finish with a clear varnish so that it does not absorb moisture, grease and dirt.

Conclusion

Combination various materials is a fairly popular type of finish. This combination expands the possibilities of decorating premises and allows you to hide their shortcomings.

The video in this article will illustrate the topic.

MDF panels are finishing material, consisting of wood fibers that are bonded together with organic resins. Due to their efficiency, they have earned great popularity in repair work. This material is especially often used for finishing public institutions - offices, shops. A wall or ceiling covered in this way will look aesthetically pleasing and modern. Latest technologies 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 produced.

MDF panels: advantages and disadvantages

Among the advantages of the 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 laying wiring in special heat-resistant boxes.

Installation can be done in several ways. If you install the product using lathing, then no special preparation of the walls is required. In addition, communications can be hidden under the sheathing. 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 areas of walls

Which glue to choose?

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

Among such universals we can highlight Kleiberit 636. It applies well, dries very quickly, and can withstand significant loads. It contains synthetic resins. German manufacturer provides 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.

Adhesive Moment Crystal for panels

MitreFix adhesive composition is specially designed for installation of such finishing material. By using it, you can be confident in the durability and reliability of gluing.

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

Before you decide which glue to use to glue MDF panels, you need to know what parameters are used to select the glue. The selection criteria for the adhesive mixture are:

high adhesive strength;
resistance to temperature changes;
moisture resistance;
no toxicity.

Operating procedure

Unlike the method of fastening panels using lathing, gluing them to the wall involves preparatory work. Here is an approximate algorithm of actions:

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

Installation of this finishing material using the gluing method is not a very complicated process. Even a novice master can easily handle it. However, before you begin this simple procedure, we recommend that you read the following guide: “How to glue MDF panels: video tutorial”:

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 install this finishing material again. Just paste it over old wall wallpaper.

When asked whether it is possible to glue wallpaper on MDF panels, we answer with confidence: it is possible! And not just wallpaper. Self-adhesive or even fabric will do if you have a creative approach to repairs. It is better to choose textured wallpaper, on a foam base. They will hide the joints of the panels.

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

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

Example of gluing wallpaper onto MDF wall panels

Plastic panels made of polyvinyl chloride are an excellent option for wall decoration. Thanks to the high manufacturability of PVC, wall panels made from it have firmly taken their place as the most popular material for interior work.

However, sooner or later, under the influence of external factors, PVC panels lose their aesthetics and require replacement with a newer finishing material. In this regard, homeowners often have a question: is it possible to glue wallpaper onto plastic panels without dismantling them?

Technical features of PVC panels and wallpaper

To apply wallpaper to PVC, you need to choose the right primer

It should be said right away that wallpapering plastic panels is quite acceptable. At modern development With technical progress, there are practically no completely incompatible finishing materials left. You just need to follow the technology for combining them: choose the right primer and adhesive composition.

To better understand all the intricacies of wallpapering a wall previously finished with plastic, you should familiarize yourself with the technical features of both materials.

have earned such wide popularity in interior design due to the following properties:

Affordable price. According to this indicator, PVC panels are one of the leaders in the wall panel segment.
Excellent impact resistance high humidity. Thanks to this, PVC wall panels can be used to decorate bathrooms, toilets and open balconies.
Resistance to ultraviolet radiation. PVC panels withstand impact sun rays, practically without losing brightness and color saturation.
Lightness. The panels have special locks on their edges for easy connection. By using " liquid nails"and self-tapping screws, you can glue the panels to the wall or screw them to the sheathing frame.

The glossy surface of the panels makes it difficult to wallpaper

This representative, like any other finishing materials, has its own disadvantages. First of all, this is low resistance to open flame, as well as the release of toxic chemical components during combustion.

But the main feature of PVC panels is their smooth glossy surface. On the one hand, this gives the cladding high decorative qualities, but on the other hand, it makes it very difficult to finish them with any material, both paint and varnish compounds and wallpaper.

Low adhesion rates between smooth surface plastic and any adhesive or paint composition do not allow high-quality wallpapering without special preparation.

Wallpaper

This type of decorative wall covering has been at the peak of popularity for decades. Wallpapers are able to stay on trend thanks to regular updates of the offered range. Today, wallpaper is not just paper rolls with a pattern printed on them.

Modern wallpapers also include high-tech types that have virtually nothing in common with their paper predecessors. Today, the following types of this finishing material are presented to the buyer:

paper Most simple variety, characterized by low cost and low resistance to external influences;
non-woven. A multilayer variety, where the base is a dense polymer fabric - non-woven fabric. Upper decorative coating can be made from almost any material - from paper to vinyl and fiberglass;
vinyl. Another option for multi-layer wallpaper, the main layer here is a polyvinyl chloride film. Depending on the base material and the number of layers, they can be either “light” or “heavy”.

In addition to these three main types of wallpaper, there are also more “exotic” varieties on our market: fiberglass, jute, “liquid wallpaper,” textile, etc.

Almost every type of wallpaper has its own, as well as glue developed specifically for a certain type of wallpaper.

The most complete information about technical features and method of use can be obtained by carefully reading the instructions on the package.

The table shows some symbols, applied to the wallpaper when marking it, and their interpretation.

Choose high-quality mixtures for gluing

A variety of sticker technologies can also be used. When pasting certain types of wallpaper, for example, paper or vinyl, the adhesive composition is applied both to the canvas and to the wall. When gluing non-woven ones - only on the wall, etc.

Some stick quite firmly to the base and the wallpaper, so when gluing you should be as precise as possible.

Other types adhesive compositions allow you to move the canvases along the wall for some time after they have been glued, adjusting the texture and pattern.

Most adhesive compositions are designed for gluing wallpaper to a fairly porous base with good adhesion. Only on such bases can you properly glue the canvas without the risk that it will completely come off or swell with a bubble in the near future.

Gluing technology

For better adhesion to PVC wallpaper, you can upholster with fiberboard

Due to the above-mentioned features of both PVC wall panels and wallpaper adhesive compositions, it is not possible to obtain a sufficiently strong adhesion between them. Therefore, in order to, it will be necessary to increase their adhesion. You can do this in two ways:

Covering PVC walls with another material, more suitable for working with wallpaper glue. It is best to use in this case fiberboard sheets- they are quite cheap, easy to cut and install, and are also great for gluing wallpaper on them.
Increased adhesion of PVC panels themselves.

The first option is quite understandable - fiberboard sheets are simply attached on top of PVC panels using self-tapping screws. The second requires special consideration. Preparing old polyvinyl chloride surfaces for wallpapering includes several stages.

Processing with abrasive materials

Abrasive sponge

Initially, the old plastic surface is thoroughly cleaned from dirt, dust, grease, etc. To do this, use a sponge soaked in soapy water or any means household chemicals. After all dirt has been removed and the surface of the panels has been dried, it should be made smooth. plastic surface rougher texture.

To do this, you should use the so-called Scotch Brite - an abrasive sponge. It needs to be properly processed over the entire plane of the panels. The movements should be intense, and sufficient pressure should be applied to the washcloth so that the glossy surface is covered with many small scratches.

In the absence of Scotch Brite, to give the plastic plane a rough structure, you can use fine-grained sandpaper or grinder with a zero circle.

After such processing plastic panel to the touch it becomes indistinguishable from a surface covered with putty or well-leveled plaster. That is, the adhesion of PVC panels using this operation was increased to quite acceptable levels.

Primer

Apply several coats of primer

Before applying the primer, the surface should be cleaned of fine dust remaining after treatment with abrasive materials. The primer composition is applied to the surface of the panels using a paint brush or roller. To do this, you should use a special primer composition designed for treating glossy surfaces - tiles, glass, plastic.

Considering such a “complex” base as a plastic plane, it is advisable to apply it in two to three layers. In this case, each subsequent layer must be applied no earlier than the previous layer has dried. After the primer has completely dried, you can begin gluing the wallpaper.

Wallpaper glue

After preparation, almost any glue should form a good adhesion to the PVC panel.

However, experts still recommend playing it safe by using a special composition for pasting wallpaper, prepared with your own hands; for this, ordinary wallpaper glue is taken and diluted in accordance with the type of wallpaper used (vinyl, non-woven, etc.).

Then universal PVA glue is added to it in a proportion of ¼ of the total mass of glue. For more information on how to hang wallpaper, watch this video:

PVA can significantly increase technical specifications any wallpaper glue, and such a composition will provide much stronger adhesion between the PVC panel and the wallpaper.

MDF panels are an excellent decorative finishing material, which is characterized by high installation speed and the absence of the need for “wet” work at all stages of finishing.

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

Fastening 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 guides, to which MDF panels are attached using nails, screws or clamps) and chemical - using adhesives.

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

Glue for MDF - review of the best options

The most commonly used adhesives for MDF panels are:

Liquid nails. A universal adhesive characterized by high adhesion, resistance to corrosion and moisture. Liquid nails do not react with substrates, unlike deep penetrating glue.
Polyurethane (or construction) foam. 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, plasterboard, 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, you need to take into account the specifics of working with it (time for primary fixation, final drying time, method of application, service life, necessary tool and materials, etc.).

Installation of MDF panels with glue - instructions

Let's consider the technology MDF installation using the adhesive compositions indicated above.

Liquid nails (similar to - universal construction 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 flat. Otherwise, the panels will follow all the unevenness of the walls or peel off in places where they do not fit tightly.

How to glue MDF to a wall

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

Degrease the surface, remove all dirt, and fill the crumbling areas with putty.
Before starting work, you need to make sure there are no irregularities using building regulations, long level or other tool.
The glue is applied in wave-like movements or in another way (for example, pointwise in 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 installing in places of greatest load, the frequency of application can be increased. Usually this is 10-15 cm. If the manufacturer determines the waiting time before gluing, it is necessary to maintain the required pause.
Using a construction bubble or laser level the starting panel is installed at the desired angle (depending on the intended pattern and installation direction). Most often used vertical installation panels. You should start from the corner.
The glue on the first panel must have time to set to the base before installing subsequent ones (the same principle applies to other difficult junctions, for example, internal or external corners). Setting time depends on the type of glue (see instructions).
Thanks to the tongue-and-groove connection, subsequent panels can be installed 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). The glue should be applied to the middle of each side of the decorative corner (so that when pressed, excess glue does not come out).

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

Option 2. Polyurethane foam.

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

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

Basic installation errors

For liquid nails:

Do not overexpose the glue before installing the panel on the base. Otherwise, adhesion will be significantly lower.
Incorrect application of glue - MDF panels will lose their attractive appearance if glue gets on the decorative front surface.
Wiping off excess glue with a heavily dampened rag may cause the decorative coating to peel off.

For polyurethane foam:

For gluing, use foam with a low shrinkage coefficient and professional tool(high-quality guns for construction foam can smoothly and strictly dose regulate its supply).
If you do not wait for the first panel to set, then when subsequent panels move, the foam may collapse and not be fixed to the base.

Question: why can’t you glue MDF onto liquid nails?

Liquid nails glue is distinguished by its versatility. It is suitable for installation large number various building materials. And if “wood” is included in the list of materials to be glued, then liquid nails are not only possible, but also must 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 in the store they can be on the same shelf).

However, sealants for gluing MDF panels are not recommended, since their main purpose is to fix plumbing products and seal seams.

How to glue MDF - features of installation work
You are interested in the question of how to glue MDF. Let's consider the technology of installing MDF using liquid nails and polyurethane foam.

Go over the joints with sandpaper, then prime them and seal them with putty and glue a sickle mesh. After this, you need to thoroughly prime the entire area of the MDF wall and you can glue the wallpaper. Why don't you want to dismantle the MDF and put wallpaper on the main wall? What are these unnecessary, extra layers for? The work will not be much more, but the area will increase.

Wallpapering on MDF panels? Are you serious? It's up to you though. And for that matter, I recommend using it better. for sealing your grooves, hard wax. Or wood putty that matches the color. In general, colored sealants will still work. It’s really difficult to match the tone with them, although you still have to cover them with wallpaper. The main thing is that your sealed recesses do not differ significantly in color from the panels themselves. Through thin wallpaper, such a difference may become noticeable over time.

Putty will not work on wood; use automotive putty for metal based on epoxy resin. This is the only way the putty will stick to the joints of the panels; plastic without an adhesive base will not hold the putty even with serpyanka - there is such a negative experience. Then finish the seams sandpaper, what would happen without the “shells” and you can glue wallpaper. but it is better to take glue based on bustylate.

You have already been given advice/recommendations regarding sealing seams on MDF panels, I will add only one thing to you (actually on preparing them for gluing). Just know that when wallpapering, your panels will have to be completely puttied to ensure good adhesion (adhesion) of the wallpaper to its surface. And don’t forget about the primer.

It is not necessary to putty completely, of course there will be no adhesion with simple wallpaper glue, it will not stick wallpaper on MDF properly, but... you still need to level the surface, and for this you just need to putty the joints. And you need to glue it, for example, onto bustilate, the glue is perfect for such a case. You can use PVA glue. It is possible to use Titan, but it is very difficult to work with it over large areas.
