What can you glue the laminate on to the wall. How to lay the laminate on the wall with your own hands correctly, without mistakes, with minimal costs

Laminate wall decoration - does not require professional skills and great physical effort. In general, this material was developed as a versatile floor covering, but it soon became clear that it could be used on other surfaces as well. Firstly, its decorative appearance is great for creating various types of interiors. Secondly, at its price, it is much cheaper than many other finishing products.

Laminate has several significant advantages that set it apart from other materials. Some of them:

  • The coating has good wear resistance properties. They were laid on the basis of its direct purpose. It is unaffected by most contaminants. Easy to clean.
  • Decorative look - allows you to create individuality. A variety of colors and textures make it truly versatile.
  • The cost is significantly lower than other types of finishes, while its durability is much higher.
  • It perfectly tolerates high and low temperatures, but not sudden changes in them. Possesses significant fire resistance.
  • Mounting the laminate on the wall does not take much time. All work is done very quickly.

Attention! Laminate has significant advantages. It can be used in any environment. However, the use of this material is not recommended - in rooms with high humidity.

Selection rules

Don't think that all laminate flooring has the same properties. No, like other types of products, it has a number of varieties that determine its performance.

  1. A distinctive feature of this material is the presence of abrasion resistance. It is determined by the class that was assigned to it.
  2. For wall cladding, you do not need a high class (the highest is 34), but you do not need to choose the lowest (it is 21). Better to give preference to average values.
  3. They are immediately determined with texture and color. This is very important if work is required over large areas. The fact is that different parties can have significant differences, different shades. Therefore, it is better to make a purchase simultaneously.
  4. The presence of a certificate of conformity is a prerequisite. Materials used for interior decoration must be environmentally friendly.

The choice of laminate, like any other finishing materials, you need to pay special attention

Wall mounting

Laying the laminate on the wall is done in two ways:

  1. By creating a lathing (frame).
  2. With glue - the material can be glued to the surface.

Attention! To fix the laminate, use special glue or liquid nails. It should be emphasized right away that this type of finishing requires no less preparation than the construction of a frame. It can only be glued on a perfectly flat surface. If you ignore this moment, then all joints and distortions will be immediately visible.

Also, you can use drywall sheets as a surface that will be sheathed with laminate.

Method one - glue

So it all starts with preparation:


  • The wall is completely cleaned, all extraneous elements are removed.
  • It is immediately determined which type of preliminary finishing will be chosen. This can be - puttying the surface or sheathing with drywall sheets. In any case, you need to get a perfectly flat surface.
  • The required amount of materials is calculated. A minimum stock of 7-10% is taken into account.
  • The tool is being prepared:
    electric jigsaw or hand saw;
    drill and screwdriver;
    trowel or glue gun;
    level;
    mallet;
    rags.
  • The elements of the door structure are removed - platbands. They will need to be installed after all the work. If the doors have not yet been installed, then you should not rush. It is possible to install the box, but not to make the cladding (do not use extras) - until the laminate is laid.

Directly installation:


Thus, a sufficiently attractive surface is obtained, but only if the base has been properly prepared.

Advice! It is required to monitor the height difference of the walls. This is especially true when it is time for the top row. Correct measurements allow accurate trimming.

Method two - we make a crate

It is believed that this particular technology is the most reliable. It is better if a material is chosen that has a significant length of strips. This will cut the work in half. In addition, laying the laminate on the frame does not require leveling the walls, which saves budget. But, there is one drawback - the crate "eats" some area.


It all starts with the construction of the frame:

  • For work, a bar of 40 * 40 or more is used.
  • Calculate the number of uprights. This is quite simple - based on the length of the chosen laminate, considering that it must be fastened in three places.
  • All slats are drilled out at once (step 250-300 mm.). For quick work, it is better to take one hole stencil as a basis.
  • One centimeter is measured from the floor and ceiling. At this height, all vertical posts will be fastened.
  • The required intervals are marked along the wall. But they should not be more than 40 - 50 cm.
  • With the help of one rail, which has been pre-drilled, the attachment points are marked (along the entire wall).
  • Dowels are driven in.
  • The first rack is installed. They immediately bait her. The main thing is to do the alignment correctly. For this, a level is used, and a substrate is placed under the rail itself. Further, the procedure is repeated.
  • Thus, a framework appears that covers the entire surface.

Timber frame
  1. The first row is fixed according to this principle: the first bar is screwed to the rack, this is done at the very bottom, where the plinth will be located. Use screws that have a countersunk head.
  2. For further fastening, it is better to use clamps. Docking of elements occurs from the selected lock.
  3. And again remember that the laminate is laid in a checkerboard pattern.

The place of the lock, where the kleimer will be attached, is best cleaned first. That is, to drown a little. Then the connection will not be difficult.

In principle, the crate can be made not only for the horizontal arrangement of the elements. If you increase the number of racks, then you can create a diagonal pattern. But such work will require more strength and concentration.

On a note! You can use a metal profile that is used to fasten drywall sheets. Then you will need to choose the appropriate fittings. And also we must not forget that the space that remains between the wall and the material can and should be used for additional insulation and waterproofing.

As a result

How do I lay laminate flooring on the wall? Very simple. You need to follow a fairly simple technology and take into account the characteristics of a particular room. And also forget forever that this material is made mainly for the floor.

Recently, an interesting design solution has been the decoration of walls in residential and office premises with laminate. We will try to talk about how to put the laminate on the wall, what the pros and cons are present in this finishing option.

Design with laminate wall coverings

Beautiful and practical laminate flooring on the wall in the interior of the apartment is gaining more and more popularity.

This is due to its properties:

  • ease of installation even an inexperienced master will figure out how to glue the laminate on the wall;
  • variety in the choice of colors, textures, pictures;
  • antistatic;
  • wear resistance, which often attracts pet lovers, because the laminate on the walls makes it impossible to leave claw marks;
  • relatively inexpensive laminate price;

Laminate wall panels in residential premises are typical for hallways, in which they are used as finishing on half of the wall, that is, to the height of one laminate plank.

In living rooms, wall laminate is usually used to decorate TV panels; in a bedroom, they can cover a part of the wall at the head of the bed.

All interiors are unique and it so happens that absolutely all walls are made of laminate in the apartment, except for the bathroom.

And not only walls, recently there has been a tendency to use laminate flooring for installation on walls and ceiling at the same time.

Choice of laminate

When choosing a laminate, it is usually determined with the load that it will be subjected to.

But this rule works for laminate flooring if we lay it on the floor.

Choosing a laminate for the walls, you can stay at the lowest class - 21, which is intended for floors in a sparsely populated apartment. This will be the most affordable option.

Considering that the loads on the wall surface are minimal or completely absent, there is no need to buy a higher class laminate flooring.

Laminate is produced today in a wide variety of patterns, colors and textures. You can choose a wall laminate for interior decoration in the design solution that suits you (see)

Installation of laminate

The question arises, how to lay the laminate on the wall, is the method of wall laying different from the floor?

There are two methods:

  • glue;
  • wireframe.

Glue method provides for a very thorough preparation of the walls. They must be leveled with starter plaster or drywall. The permissible unevenness should not be higher than 1-3 mm.

How to glue the laminate? It is possible to fix the laminate to the wall surface with liquid nails if it is a lock, and if it is glued, it is attached only to glue.

Laying the laminate on the wall with the glue method is carried out using a special glue.

If used lock method, then laying on the walls is done on liquid nails or special fasteners are used, which are used when installing MDF panels.

Important. Before starting work, all laminate flooring must be unpacked. Leave it for forty-eight hours in the exact room where the installation will be done. This will enable the laminate to acclimate to the temperature and humidity level of the room.

Tools and materials for laminate installation

Laying the laminate on the wall with your own hands is quite possible, you just need to properly prepare and get it.

To install laminate flooring on walls, you will need:

  • pencil and ruler;
  • silicone;
  • screwdriver and screws;
  • glue or liquid nails;
  • a bar with which the laminate is knocked out;
  • jigsaw or hacksaw for wood;
  • hammer;
  • sills, moldings, layouts;
  • the laminate itself.

Technology for laying laminate on glue

When gluing laminate flooring, it is best to assemble panels from panels, adjusted to the size according to the design, on the floor. The side ends of the panels are thickly smeared with special glue and glued to each other.

The finished panels are glued to the pre-marked parts of the wall, pre-greased with glue.

As you can see, the technology of laying the laminate on the wall with the glue method is not complicated, it is quite possible to do this kind of work with your own hands.

A sufficient number of video clips from various programs, such as "School of Repair" or "Housing Problem", are presented on the Internet, which show in detail the entire installation process.

Important. Work on the installation of the laminate must be started from the lower left corner of the wall to be covered. Door platbands are preliminarily removed, and at the end of installation they are fixed to the old place, but on top of the new finish.

Installation of laminate on a crate

The method of laying the interlocking laminate involves fastening it to the lathing or, with a flat surface, to liquid nails.

The liquid nail option is similar to the laminate glue option. The only difference is that when collecting laminate shields, we fasten them with a lock fastener, and then we go through with a sealant.

In this case, the installation of the laminate on the wall is carried out on liquid nails.
The lathing for the installation of a laminate covering on the wall can be made of wooden blocks, slats or wall rails of a metal profile.

The panels are fixed on the crate with special fasteners, which are used when working with Euro lining or MDF panels. The parts of this fastener are called clamps.

If the kleimer interferes with the entry of the edge of the next board into the groove of the previous one, then the possibility of cutting the lock is allowed.

When installing the laminate on a wall, just as in the case of floor installation, small gaps should be left between the floor / ceiling and the panels.

The procedure for the production of work:

  • take measurements, calculate the required amount of laminate, moldings, sills, lathing details;
  • apply the necessary markings on the wall with a pencil and a ruler;
  • remove all platbands from doors and windows;
  • mount the wall crate, that is, the lattice frame;
  • start the installation of the laminate from the lower left corner and walk clockwise, cutting the elements in the corners of the room with a hacksaw or an electric jigsaw;
  • we arrange the laminate planks during installation in a checkerboard pattern;
  • before snapping the lock, treat the joints with silicone;
  • external and internal corners must be finished with a special aluminum profile and also filled with silicone.

An excellent design solution is to use wall laminate, especially in combination with floor laminate. It is interesting that this cheap and beautiful material is laid not only on the walls or floor, but also on the ceiling.

In any of its applications: floor, ceiling or wall, laminate flooring blends well with the interior, retains its properties - durability, reliability, and decent appearance.

A large selection of laminate patterns allows you to create a variety of designer interiors. For example, a laminate with a stone finish will look great in a kitchen or hallway, and a wood look will look great in a bedroom or living room.

We have detailed how to lay laminate flooring on the wall. The same happens on other surfaces. It's only up to your imagination and skillful hands.

Experienced owners who are thinking about decorative wall decoration know that to give the room respectability and accentuated splendor, it is most profitable to use wood and MDF, but the use of these materials is often limited by their significant cost. The age of innovative technologies has allowed finding a cheaper alternative to wood and MDF panels, making repairs available to everyone. And that alternative is laminate.

Laminate for wall decoration: the main advantages

It makes no sense to question the practicality of laminate as a material for wall decoration, since it has been tested for durability as a floor covering for a long time.

Previously used as a cheaper alternative to the usual wood and wall panels, today laminate flooring is gradually replacing its competitors due to its undeniable advantages.

The main advantages of laminate as a material for wall decoration:

  • High environmental friendliness due to the wood component that is part of the laminated panels;
  • Durability is an important advantage of the laminate, which is relevant in the conditions of compliance with the operating rules;
  • A wide selection of textures and colors is the advantage of laminated panels, giving life to the most daring ideas of designers;
  • Ease of installation allows you to finish the walls without the help of specialists;
  • Ease of operation and high practicality allow you to easily carry out wet cleaning of the room without fear of ruining the laminated panels.

Laminate disadvantages limiting its use

Despite the large number of advantages, laminated panels also have disadvantages that prevent them from being used as a finishing material in any premises.

This is mainly due to the low resistance of the material to changes in temperature and humidity indicators, which exclude its use in the bathroom and kitchen.

For finishing the hallway with the help of a laminate, there are no restrictions, since the possible changes in the indicated microclimatic factors in this room are of a short-term nature.

The main parameters to be guided by when choosing a laminate

Before moving on to wall cladding with laminate, it is important to choose the right material, focusing not only on its cheapness, but also on the operational factors affecting it.

In this regard, when choosing a material, you need to focus on the following parameters:

  • Possible level of abrasive and mechanical stress. This factor is important to consider when choosing the thickness of the material. Frequent cleaning and constant exposure to sharp animal claws is a reason to abandon overly thin panels;
  • Installation method is perhaps the most important factor in determining the choice of material. The opposite statement is also relevant - the type of laminate determines the way the material is attached to the wall.

The main types of laminate

Considering this, the following types of laminate are distinguished, which must be familiarized with before answering the question: "How to fix the laminate on the wall?"

  • Adhesive laminate, characterized by smooth edges and no locks. Fastening of such panels is carried out by means of liquid nails;
  • The tongue-and-groove laminate is characterized by the presence of a tongue-and-groove lock. Laying the laminate on the wall involves the use of glue, without gluing the locks. In the case of fastening the material with a dry method, strips like a lining are fixed with small nails into the groove of the tongue;
  • Click laminate is a more modern modification of sheet piling panels. Its attachment can be carried out with glue to the lathing made of wood.

Installation methods for laminated panels

Thus, there are fundamentally different options for mounting a laminate on a wall:

  • The first method: direct fastening of the laminate to the wall using liquid nails or glue, which allows you to easily combine the texture and color of the panels. However, the walls in this case need additional preparation, since they must be characterized by a perfectly flat surface;
  • The second method involves laying the laminate on a wooden crate, which is pre-assembled from slats and attached to the wall. Despite the obvious advantages in the possibility of additional sound insulation, the owners often refuse this mounting option, since the size of the room in this case will decrease.

Installation of laminate on the wall: work sequence

The first stage of finishing work is to calculate the required amount of material. Considering that the fastening of the laminate is carried out to a flat surface, it will not be difficult to calculate. To do this, the width of the wall is multiplied by its height and another 10% is added to the resulting number, which are necessary to fit the material. To rationalize the use of laminated panels, experts advise you to choose the most suitable size planks.

Before answering the question: "How to fix the laminate on the wall?" it is necessary to clarify that the preparation of the working surface is considered a mandatory stage of finishing activities.

In the case of using adhesive laminate, specialized measures are not required, it is enough for the wall surface to be flat and dry. For a laminate, the features of which imply its attachment to a frame base, it is necessary to prepare a wooden crate.

For its manufacture, it is recommended to use wooden slats with an average diameter of 30 mm, which are fixed with self-tapping screws at a distance of up to 40 mm. The installation of the slats is carried out strictly perpendicular to the future panels. At the same time, it is advisable to use the building level.

Further, they are determined with the choice of the starting point. First of all, it depends on the spatial orientation of the panels, which can be located both vertically and horizontally. Horizontal laying, in turn, is directly dependent on the version of the wall cladding, which is also different and can be either full or partial.

If a complete wall cladding or only the upper part of it is planned, the panels are fastened from the ceiling and carried out in the direction from top to bottom. Otherwise, the wall is finished in the opposite direction, starting from the floor.

In the case of vertical orientation of the panels, the decoration and design of the walls with laminate starts from the corner of the wall in the direction from left to right. So that the finishing of the corners does not spoil the appearance of the room, experts recommend leaving deformation gaps of 15-20 mm from the corner of the wall.

The method of fixing the laminate also depends on its type: when fixing the adhesive laminate, the back surface of the panels and the walls are coated with glue, after which the planks are fixed to the wall using a level.

The fastening of the second row is carried out in the same way, however, before fixing the strip with glue, it is inserted into the lock of the previous panel. To achieve additional fixation, the lock is secured with nails or staples. In the case of wall decoration with sheet pile laminate, its fastening to the crate is carried out using clamps fixing the panel from above and below.

After fixing the laminate on the wall, the photo of the room after finishing can be seen below, it is not recommended to leave in its original form the sections of the wall in contact with the floor and ceiling plane.

There are many varieties of laminated wall panels. They are made from different materials and different formats, and auxiliary profiles are produced for them. But no less popular for wall decoration is a laminate designed as a floor covering. Although because of this, its installation takes place according to different rules.

Laminate differences

For the most part, the interlocking laminate, as a floor covering, is not intended for rigid attachment to the base. This is a floating floor type, the main feature of which is the reliable fixing of the floorboards to each other. Typically, a firm grip is provided by an end lock connection with a complex snap-on profile. Of course, you can also find an adhesive bond, but rarely.

Finishing with wall panels requires the opposite - rigid attachment to the base, and the profiled end is an additional option, providing a hidden type of installation.

The most common type of slatted panels is a lining with a regular tongue-and-groove end. Therefore, often the laminate is also mounted to the walls - through the groove, fixing it to the lathing with fasteners. But this is not the only type of installation.

Mounting methods

There are three ways to fix the laminate to the wall:

  • with glue;
  • nails through the bottom wall of the spike to the sheathing bar;
  • clamps to the crate.

Fastening with glue

Laminate flooring can in essence be considered a type of fiberboard, therefore, an anhydrous glue is needed to fix it. This is especially important if the leveling of the wall surface is carried out using gypsum board or plywood - with prolonged contact with a humid environment, either the base or the panels themselves can swell and "lead".

You can use parquet glue, but not dispersion, but solvent-based or two-component.

The surface of the wall should be nearly perfect. If small irregularities of the subfloor can be compensated for with a substrate, then for a wall this is not possible. The glue is quite expensive, it is applied in a thin layer, therefore the uneven surface of the wall will lead to a decrease in the adhesion area spot, which will affect the reliability of the fastening.

After leveling the wall (with plaster, putty, using drywall), it must be primed and dried.

Then, using a level, lines are applied to the surface, which will be guided during the installation of the laminate.

The most common laying pattern is offsetting adjacent rows by half the length of the plank.

The first row starts from half. They smear its seamy surface and the contact spot on the wall. Press for a short time, then "tear off" and allow the glue to weather, then press again until the initial setting. In principle, this is a technology for working with fast-drying adhesives, which can differ in the holding time at each stage. In this algorithm, the first row of laminate is glued, and then all the others.

The second row starts with a whole panel, and the third row again with a half. The technique of joining panels between rows depends on the type of laminate lock.

The advantage of this installation method is the minimum loss of useful volume.

There are more disadvantages: significant labor intensity, high consumption of expensive glue, low environmental friendliness of quick-drying anhydrous adhesives. In addition, walls that have been leveled with plaster and putty may not have sufficient topcoat strength to support the weight of the laminate.

Fastening on the crate

Mounting the laminate to the wall on the lathing has the same sequence of operations as when finishing with clapboard:

  1. Choose the direction of laying: vertical, horizontal, diagonal.
  2. Markings are made perpendicular to the direction of laying for fastening the battens. Its pitch should ensure the fastening of the laminate at least three points - along the edges and in the middle. Therefore, the axial distance between adjacent rows of the crate should be fixed: 1/2 or 1/3 of the length (the only exception can be for the lower and upper row of the crate). Reducing the offset pitch of the laying pattern to 1/4, which is practiced for flooring, is technically impractical, given the width of the batten for the lathing.
  3. For the lathing, choose a wooden block with a width of at least 40 mm, since the distance from the edge of the short end of the laminate strip to the attachment point must be at least 15 mm. The joints of the laminate planks in each row should be in the middle of the batten.
  4. In the bottom and top row of the batten, you can use a smaller bar. It is necessary to start and end the installation of the row not in the center of the bar, but at its edge.
  5. The lathing bars are attached to the wall in accordance with the markings, observing the general level of the surface.

An adhesive laminate with a smooth spike-groove profile is mounted to the lathing in the same way as the lining: with a thin nail through the bottom wall of the groove or using cleats.

To attach the locking laminate to the crate, clamps are usually used, but under them you will have to:

  • for the Click lock, cut the profile of the bottom wall of the lock groove at the attachment point;
  • for the Lock, cut the lower part of the tongue of the panel to be inserted at the attachment point.

Disadvantages of laminate as a wall decoration material

Among all types of wood-based finishing materials, laminate is one of the most expensive (only parquet boards and parquet are more expensive). Previously, it would be possible to save on the class, but below 31 classes are no longer released. The cheapest domestic laminate with a thickness of 6-8 mm will cost about 400 rubles. per sq. meter. Therefore, there is no need to talk about the availability of this type of finish.

The high wear resistance of the laminate, the use of HDF in the base layer and the complex profile of the lock joint - all these are redundant qualities for wall panels that will not "work" and will not affect the durability of the finish.

Installation of laminate on walls is more difficult than for wall panels. Even with battens, more materials, fasteners and more time are required.

The only thing that justifies the expended funds and efforts is high decorative properties and the possibility of creating a harmonious interior. Moreover, it is not necessary to sheathe all walls (or the entire wall) with laminate - usually it is enough to select a separate area.

Laminate was created as a floor covering. However, misuse of finishing materials has always been a guaranteed way to make your home unique, hasn't it? We will try to find out how to fix laminate flooring on the wall in this article.

Why is it needed

Traditionally, PVC and MDF panels are used for quick and easy wall decoration.

What are the advantages of laminate flooring?

  • It is significantly stronger than both types of panels. If the PVC panel is easy to break with an accidental impact, then the laminate can withstand a fairly large force applied to it.
  • Compared to MDF panels, it is less hygroscopic- both due to the denser structure, and because its back surface is protected by a polymer layer.
  • Fastening the laminate to the wall is also practiced because the tiled wall is very easy to maintain.: you can safely wash the laminate with non-aggressive detergents (see)

Please note: in this sense, PVC panels are in a more advantageous position. They are not afraid of any household chemicals at all.

The obvious disadvantage is the price of the laminate. It is slightly higher than that of wall panels: the difference is from 1.5 to 2.5 times.

Problems

Where can we go without them?

Fastening laminate to the wall is associated with the following difficulties:

  • The stuff is pretty heavy. The fixing and the surface on which the laminate will be mounted must be strong.
  • Although the hygroscopicity is lower than that of wall panels, the cellulose at the base of the material does not lose its properties: the material swells with changes in humidity. If the coefficient of thermal expansion of MDF is small, then fluctuations in atmospheric humidity have a quite tangible effect on the linear dimensions of the laminate board.
  • In the case of wall panels, the lower protruding part of the groove is used for fastening. It is screwed on with self-tapping screws or nailed. However, the most common type of laminate is click-lock.

Its design, on the one hand, rigidly holds the panels together, on the other hand, the head of a nail or self-tapping screw in the click lock puts it tightly closed. At the very least, there will be a wide and untidy groove between the panels.

conclusions

  • You only need to fix the laminate on a solid surface. A drywall sheet planted on plaster can simply fall off along with the massive coating.
  • It is best to avoid laminate flooring in wet areas. Bathroom, toilet, kitchen get off in other ways. Laminate on the walls can be safely mounted in rooms with constant moderate humidity.
  • Avoid rigid fixing of panels. The glue line must be elastic; other methods of fastening must allow the panels to move within a small range when their linear dimensions change.
  • The fastening must not interfere with the laminate board lock.

Mounting options

So, how to attach a laminate to the wall with your own hands?

Smooth, durable surface

The easiest method is suitable for plastered walls or walls covered with securely fixed drywall. Laminate boards simply sit on liquid nails. After hardening, the adhesive bond will retain slight elasticity and will be quite strong.

There are several nuances:

  • At the bottom, it is worth mounting an emphasis for the first line of boards. Otherwise, they will begin to slide under their own weight.
  • In this case, it is better not to knock the boards into the lock through the boss, but insert them with a slight break and snap them into place, pressing them against the wall. In this case, the lower board must be held.
  • Rows of boards must be assembled with an offset of the transverse joints from row to row.
  • As an option for a small wall, you can assemble a laminate shield on the floor and glue it to the wall as a whole. Of course, this will not work with a wall of a large area.

Tip: You can additionally fix the laminate cladding with the stained mounting strips. The wall will look like a half-timbered house. In this case, the holes in the laminate for fastening the rails must be drilled with a margin of diameter - precisely in order to avoid rigid fixation.

Liquid nails are the simplest and most obvious solution.

Uneven wall

How to fix a laminate on a wall that has noticeable irregularities?

With a step of no more than 60 centimeters perpendicular to the direction of the laminate board, the crate is assembled. The material can be either a galvanized profile or a bar with a size of 40x40 millimeters.

Then everything is the same as with a flat wall. Laminate boards rest on a profile or rail at the bottom and are mounted on liquid nails. Ligation of transverse joints is required.

Kleimers

How to attach laminate flooring to the wall without using glue?

Kleimers will help - galvanized staples, which are made specifically for fastening laminate and lining to walls and ceilings.

There are two types of staples that we need.

  • Kleimers with serrated protrusions are driven into the sawn-off end of the laminate board and are fixed with self-tapping screws to the crate or wall.
  • The flat-ribbed brackets press the protruding part of the click lock of the board, securely fixing the laminate and not interfering with the connection to the adjacent board.
