Wall decoration with wallpaper and moldings. Interior moldings. An inexpensive way to make your home unique. Photo: examples of decorating various rooms with moldings

Molding in a modern interior is a multifunctional detail that can serve as a decorative element, hide flaws in a structure or surface, zone a room or separate various finishing materials from each other, protect corners and joints from damage. With all this, molding today is an effective replacement for stucco molding, which allows you to add notes of luxury and respectability to the design of premises at low cost. In this selection, we invite you to familiarize yourself with the options for the execution of moldings, the choice of material and the method of fastening, using the example of an extensive selection of photos with hundreds of interesting design projects.

Material for the manufacture of moldings

Modern shops of finishing materials offer us a wide selection of moldings of various modifications. They differ, first of all, in the materials of manufacture. Consider the types of moldings based on the material of execution, classifying the models from the lightest to the heaviest.

Styrofoam and plastic moldings. This is the most popular type of decorative trim. Such decor was widespread due to its low cost, low weight and resistance to moisture. Styrofoam and plastic moldings can be used in rooms with any microclimate and functional purpose. But these elements are not without drawbacks - foam products are more susceptible to damage, have low strength and durability.

Polyurethane moldings. Products are gaining popularity day by day. And this is due to the flexibility of products, ease of installation, sufficiently high strength and durability. And the relatively low cost attracts buyers and allows them to “turn a blind eye” to low environmental friendliness.

Natural wood moldings. The beautiful natural pattern and naturalness of the material will always attract buyers. The absence of toxic emissions, the possibility of using it even in children's rooms and high aesthetic qualities make wood a material for all times, despite the presence of cheaper artificial analogues.

Marble, metal and plaster moldings. Beautiful, luxurious, natural - you can pick up a lot of epithets for such products. They are able to truly decorate the classic style of decoration of any room. But the high price and high weight of the structures do not help them increase their popularity for use in the design of living spaces. Such moldings are most often used for the restoration of historical interiors or the creation of very expensive design projects for spacious rooms in baroque style.

I would like to highlight in a separate group self-adhesive moldings... Most often they are made of a rubberized plastic material and are used to join the bathtub and the surface of the finished wall. The groove molding, which is used most often as a decorative element, has gained no less popularity.

Classification of moldings for modern interiors

The variety of modern moldings is impressive. These are not only strips for decorating walls and separating finishing materials among themselves. Floor and ceiling skirting boards, mirror frames, decorative elements on furniture, door and window frames, cornices and panels - these are all moldings. A variety of modifications is involved and a wide range of places for use - moldings are used not only for finishing the surfaces of premises, but also for decorating furniture, various designs.

Ceiling moldings

The element of dividing the surfaces of the ceiling and the wall, which is familiar to many of us, is often called the ceiling plinth. Sometimes this molding is called caniz. In any case, the ceiling molding allows you to make the most aesthetically pleasing transition from the ceiling to the walls and hide the flaws in the finish, create a clearer border between the finishing materials and outline the geometry of the room.

Conventionally, all ceiling moldings can be divided into simple and complex. The name speaks for itself - simple models are distinguished by their laconic design, complex ones have stucco decoration or multi-tiered execution. Also, all ceiling moldings differ in width - this value can range from a couple of centimeters to a couple of tens of centimeters. It all depends on the size of the room itself, the height of the ceiling and the style of interior design. For small rooms, it makes no sense to use complex and wide moldings; in spacious rooms, with high ceilings and pretentious interiors, the use of ceiling decor with patterns and stucco molding will be justified.

Ceiling moldings can be made from the following materials:

  • gypsum;
  • wood;
  • clay;
  • polyurethane;
  • polystyrene.

As practice shows, it is easier to work with moldings made of artificial materials. They are small in everything, easy to install, and given that the decor on the ceiling is subject to the least mechanical stress and wear, such models can last quite a long time.

In a special group of ceiling moldings, I would like to highlight the skirting boards that form the joint between the ceiling and storage systems that come into contact with it. Most often, built-in wardrobes or whole furniture sets act as such. To meet such a design in a modern kitchen will not amount to tons of ore - many people prefer to mount the upper tier of kitchen cabinets from the ceiling itself.

Floor moldings

The function of the floor moldings is similar to the purpose of the ceiling elements - delimiting surfaces and finishing methods, only in this case we are talking about walls and flooring. Floor moldings help hide imperfections in finishes and protect the joints between floors and walls. The width of the floor moldings also depends on the size of the room and the height of the room, the chosen design style.

Floor moldings can also be made from different materials and differ in style. In modern models, most often you can find special cable channels located inside the moldings. Such a plinth will help hide wires and cables from the eyes.

Wall moldings

Wall moldings are used very often. They can perform an exclusively decorative role, serve to mask flaws in finishing or architectural imperfections, hide joints or zone rooms, separate one type of wall decoration from one another. Wall moldings can be glued to wallpaper or decorative plaster, directly to walls and then painted in a single tone, can act as a contrast or blend with the overall palette of finishes.

Most often, wall moldings are chosen based on the design and color scheme of ceiling and floor skirting boards - to obtain a harmonious image of the room. But a lot also depends on what kind of decor element the owner of the room wants to create, to highlight any element or zone, hide flaws or "drag" attention from unattractive objects to the most advantageous ones.

One of the most popular ways to use wall moldings is to frame inserts from a different finishing material. For example, plain wallpaper or decorative plaster are used for wall decoration, and molding frames contain inserts of embossed textiles, velvet or metallized wallpaper (an expensive material that gives the interior a touch of luxury).

The second option for using wall moldings is associated with a combination of the color of the walls and the shade of decorative elements. Most often, snow-white moldings are glued to a single-color wall decoration in any color scheme. The more spacious the room and the more natural light sources, the brighter and richer you can use color combinations. Pastel tones of walls with snow-white moldings allow you to create an exquisite and noble image of the room ...

And contrasting combinations will add dynamism, brightness, originality and even drama to the interior ...

Another equally common way of creating trim using moldings is associated with painting the elements glued to the wall. On the one hand, a neutral background of decoration is obtained without contrasting combinations and delights, on the other, due to the presence of textured moldings and clear geometric shapes, the interior can no longer be called trivial, boring. Even neutral colors will look better with moldings.

Door, window and arch moldings

Door moldings are the most popular type of decor in this category. It is extremely difficult to imagine interior doors without platbands (this is how door moldings are usually called). The molding helps to hide the joints, imperfections in the finish or flaws in the installation of the door frame, completes the image of the doorway and ultimately makes the entire interior of the room aesthetic. Arched moldings that protect the joints of surfaces and finishes that decorate arched openings help to achieve a similar effect.

Most often, platbands for interior doors are chosen based on the material and color scheme for the execution of the paintings themselves. The harmonious image of the doorway always serves as an interior decoration. But in some cases, designers recommend using contrasting combinations, playing not only with the colors of the elements, but also with the material of execution.

A similar situation is with window moldings - they help hide flaws in the installation of windows, give openings an aesthetic appearance and, in general, decorate the design of the room. The most widespread are snow-white moldings (a universal option for any interior color solutions) and wood products with a beautiful natural pattern (brings notes of warmth to any room atmosphere).

As the name implies, this type of molding is used to decorate pieces of furniture. At the same time, moldings can be found not only on the facades of various storage systems, but also on upholstered furniture, various tables and stands, and joinery. Modern manufacturers offer us three options for decorative moldings for furniture:

  • smooth;
  • textured;
  • metallized.

As the names suggest, smooth moldings are used to decorate pieces of furniture with a smooth surface, the second type is most often used in the manufacture of facades and hardwood products, and the third is used to imitate products for various metal surfaces - gold, silver, bronze and copper.

Mounting methods for various types of moldings

As you can see, there are many options for the execution of moldings - both in terms of material of manufacture, design and method of use. It remains only to find out how it is easiest and most reliable to mount these functional and decorative elements to various surfaces. The most common options for bonding moldings to surfaces with different finishes are:

  • adhesive composition;
  • silicone (used for gluing plastic, rubber and metal moldings to flat surfaces);
  • "Liquid nails" (suitable even for porous surfaces).

When gluing moldings, accuracy, the choice of an even direction and the correct trimming of corners are of no less importance. You need to know very little about self-adhesive moldings - they are glued onto a perfectly clean and dry surface, and the protective film is removed already during the installation process.

And in conclusion

A molding is a device that can help you not only hide flaws in finishing, protect corners or joints, divide areas with different finishing materials or highlight a segment, but also diversify even the most ordinary interior. Beautiful moldings can change the image of a room, adding a touch of luxury and sophistication. It is noteworthy that at the same time you do not have to spend a lot of time and money - every owner of an apartment or house can find a molding that can afford it, and everyone can mount these functional and at the same time decorative elements.

Reading time ≈ 3 minutes

Decorative moldings are an excellent tool with which you can embody the most amazing and sophisticated interior design ideas. These are overlaid profiled parts made of wood, polyurethane, plastic, foam. They are usually made in the form of a narrow strip with a length of 2 meters. The width and shape of the product can be very different: they can be carved, convex, flat, decorated with numerous small decorative details.

Decorative overlays look good both with monochromatic wall decoration, and with textured and patterned or floral wallpaper.

  1. Wooden moldings look luxurious and give the room a chic look, but they are expensive;
  2. Foam products are inexpensive, but poorly adhered, difficult to fit and not particularly well stained;
  3. Polyurethanes are the most common, due to the optimal price / quality ratio and ease of processing;
  4. Gypsum moldings give the room an exclusive look, but they are fragile and difficult to install.

Wall moldings

To create the Empire style, Rococo and similar interior trends, walls are decorated in the interior with decorative moldings. Instead of platbands, you can decorate door and window openings with such overlays. Pasting windows allows you to visually enlarge modern small openings. With decorative strips, you can beautifully delimit the junction of different wallpapers with combined pasting of a room. The joint of different wallpapers is traditionally done at a height of 70-100 cm and wallpaper with horizontal moldings in the interior will look very appropriate.

In the classic interior style, they are used to create decorative rectangular frames on the walls. In the middle of such a frame, you can hang a mirror, lamp or painting. Moldings are used to decorate places for electric fireplaces, as well as to decorate decorative fireplaces. Sticking decorative strips on the wall is a traditional interior decoration.

Wall moldings in the interior of the apartment can be glued in the form of a rectangle at an equal distance from each other. Curved planks can be used to create geometric compositions on walls. This wall decor looks great in living rooms and in classic bedrooms. A panel or a group of photographs can be placed in each decorated sector. Sections framed with moldings can be glued or painted or covered with decorative plaster that is different in color from the main background. All the options for using moldings can be seen in the photo presented in this article.

Fastening in blocks allows you to add additional volume to the room. Any vertical stylistic solutions visually raise the room, therefore, the higher the sector, the higher the room becomes.

Ceiling moldings

In order for the living room or bedroom to look complete, you can use ceiling moldings in the interior. They are glued at the junction of the ceiling and wall. They vary in width - wide ceiling strips look perfect with high ceilings.

Molding is a type of overhead decor that is used in the interior of a room to give any part of it an additional volume, relief, as well as to separate wallpaper and other finishing materials from each other. Moldings come in a wide variety of shapes, sizes, styles and materials.

Such a decorative element goes well with paint, wallpaper, decorative plaster. Very often, with their help, they create rectangular frames on the wall, focusing on any elements of the interior - paintings, a mirror, a lamp.

Wallpaper splitting moldings are a great option to diversify and liven up the boring interior of any room without a lot of effort. With proper use, they are able to change the room, give it sophistication and aristocracy.

The use of molding in the interior

What types of moldings can be found on the building goods market, and what is their purpose:

  • For separating two types of wallpaper. Here you can call a decorative skirting board, it is placed between the floor and the wall; fillet and baguette - for corners between walls; the skirting board is placed end-to-end between the ceiling and the wall.
  • For framing. There are decorative platbands in this group - they frame window frames or doorways; frames are a fairly common variety for decorating mirrors or paintings; tiles - decoration for fireplaces and stoves;
  • Pilasters are used to cross walls, and curbs are used for ceilings;
  • Relief. Moldings designed to give walls or ceilings a relief, volume, are placed on a large area of ​​the surface and are called panels, or "medallions".

The goals pursued by the use of this decorative element can be very diverse - from overlapping any defects to creating visual illusion (expanding, narrowing the space, zoning, and so on). Since we are interested in wallpaper moldings, we will consider their features.

As a rule, with the help of moldings, wallpaper is separated from different materials or from the same material, but in different colors or textures. The modern buyer can be offered companion wallpapers that ideally match each other in color and texture and save their owner from the need to conduct a long search for suitable options.

Another reason to buy moldings is a studio apartment, where you just need to divide a small space into zones: kitchens, bedrooms, hallways, etc.

Classification of moldings by material of manufacture

Since the design, shapes, colors of moldings are presented on the modern market in an endless variety, the material used for the manufacture of these decorative elements can be very different. You can find this element of decor made of wood, plaster, alabaster. These materials look rather pretentious in finished form and, perhaps, too luxurious for stylish modern design, therefore, they are not very popular.

The most commonly seen decorative moldings are made of polyurethane. It is a lightweight, smooth material that is easy to paint, varnish or otherwise laminate. It is easy to work with it, stick to the surface (especially to the wallpaper), whether it is a straight wall or an angle between walls.

Wallpaper separation moldings can also be made from a similar material - polyurethane foam. It is much cheaper and more flexible, but it also has a number of disadvantages.

Another material for making moldings is polystyrene. Its advantage lies in the fact that when it is cut, the cut is even and smooth, without chips and defects. This is very important for the design of complex-shaped frames. They are also easy to paint and wash.

The cheapest material used for moldings is styrofoam. It is no secret that it is very light, but this quality borders on fragility. In addition, foam types can react poorly to various varnishes and paints.

How to glue moldings on the wall

What material this decorative element would not be made of is a rather whimsical thing, therefore, before starting work with the molding, let it "live" in the room for at least a day to get used to the temperature, pressure and the like.

If your choice has settled on a product not made of wood, for which self-tapping screws are required, then ordinary construction glue of the "" type will help to glue it to the wall. In addition to glue, you need the following tools to work with moldings:

  • cut template;
  • keel with fine teeth;
  • glue gun;
  • putty knife;
  • putty.

Opinions differ as to whether to glue them on wallpaper, or on a bare wall before gluing. You can choose the option that suits you best. In the first case, there is no need to adjust the wallpaper to size after installing the molding. In the second case, if you decide to re-glue the wallpaper, it will not be necessary to dismantle this decorative element (but this option is hardly convincing). If you choose the second method, it is recommended to use acrylic-based glue for gluing.

We offer you an approximate scheme of actions that will help you glue the moldings yourself to separate the wallpaper.

  1. The layout of the room (surface). It is advisable to use the decor element itself as a tool.
  2. Molding cutting. We do not advise you to trust the firmness of your hand one hundred percent in this matter, it is better to leave a small margin in case you need to align the cut.
  3. Glue application. Pasting starts with corner joints. Apply glue to one edge of the molding and spread it over the rest of the surface with a spatula.
  4. Bonding. The molding smeared with glue must be evenly applied to the wall and pressed firmly. Hold until the adhesive "adheres" to the surface.
  5. Grouting joints. Here we need a finishing putty, which will hide small gaps between the decorative item and the wall.

If you have selected moldings in accordance with the main style of the room and the appropriate color scheme, then the room can radically change for the better, and for a long time please the household and all guests.

Many years ago, designers from different countries used moldings in the decor of living quarters and for decorating furniture. Since then, this element has been in demand, then it has been forgotten. Today, decorative molding has again burst into designer fashion. Therefore, we suggest you find out in more detail what kind of material it is, what it is made of and how to use it in the interior.

What is molding?

Molding is a decorative element that looks like an overhead volumetric strip made of various materials. Usually its length starts from two meters. The width of the molding can be absolutely different - from one to more than ten centimeters.

In section, this decorative element can also be different: flat, convex, carved, curved, with many small additional details, and so on.

Types of moldings by material of manufacture

Today, decorative molding, depending on the material of manufacture, can be of the following type:

  • Foam. This is the cheapest and most common type of decorative items. They are very lightweight and highly resistant to moisture. There is also a very wide variety in appearance. In work, foam molding also does not cause difficulties. The only drawback of the material is that it is easy enough to spoil it.
  • Polyurethane. This molding is lighter than plaster, but stronger than foam. At the same time, it is also quite budgetary and is represented by a wide range. There is even a flexible polyurethane molding that allows you to create any kind of finish.
  • Wood. This is an environmentally friendly, but not cheap type of molding. It has an excellent decorative appearance, a hard surface, but at the same time it is not resistant to moisture.
  • Marble, plaster and metal. These types are not widespread as they are quite expensive, heavy and difficult to work with. Basically, these types of moldings are used to create interiors and facades of houses in the historical style, where new technologies are inappropriate.

Styrofoam and polyurethane moldings are in the greatest demand and have a lot of positive reviews. Consumers note that, in addition to the good price, they are distinguished by a wide assortment. You can choose an already processed suitable surface or decorate it yourself at home. It is not very difficult to do this, so you do not need to resort to the help of builders.

Decorative self-adhesive molding is in special demand. Many people say it is easy to use and does not require special knowledge and skills. Self-adhesive molding looks like a border, and it is made of rubber or plastic. Most often used in the bathroom to mask the joint between the bathtub and the wall.

Where can moldings be used?

Decorative molding in the interior is used for:

  • breaking walls into separate sections;
  • masking defects and inaccuracies in finishing;
  • masking joints between wallpaper, wall and ceiling, wall and door frame;
  • creating objects that attract attention;
  • protection of walls from unexpected damage;
  • creating a frame around small windows to visually enlarge them;
  • creating cornices and various;
  • giving an interesting appearance to furniture;

Depending on the application, a distinction is made between decorative moldings for furniture, walls and ceilings.

Ceiling molding

This molding is various types of moldings and skirting boards. With their help, you can not only make an interesting ceiling decor, but also mask irregularities and defects in the finish. For decoration, products made of foam or polyurethane are most often used.

Ceiling moldings can be of different shapes and widths - from flat to convex and embossed, from narrow to very wide. You can paint them in the color of the ceiling or give them a completely different shade.

Wall moldings

This type of molding has a fairly wide range of applications. They are used not only for various purposes but also as a surface around doorways, arches and windows. There are a huge number of options for wall elements: narrow and wide, even and convex, smooth and with a relief. Decorative is selected based on the size and style of the room, as well as the shape and color of the plinth.

The most commonly used strips are made of foam and polyurethane. With their help, various zones on the wall are usually distinguished, which are then pasted over with bright wallpaper or painted in a different color. That is, with the help of decorative moldings, they create frames for bright accents in the interior.

There is also a special kind of decorative strips that resemble columns. They are quite wide and embossed. The upper and lower parts have a special decorative look. With their help, you can not only make the interior in a classic style, but also mask serious defects in the coating.

Window molding is most often used in white. With its help, you can visually enlarge small windows and mask the joints between the slopes and the wall.

Furniture moldings

Furniture decorative molding is used to decorate various joinery products. It can be of three types: smooth, textured, metallized. The latter helps to create an imitation of furniture, in whole or in part, made of metal.

With the help of furniture moldings, you can update old ones and create designer interior items without much material costs.

Since the main function of the molding is the decor of the room and interior items, then during its installation you need to work very carefully so as not to damage the surface of the strip and not leave any traces on it.

Decorative elements are most often attached using a special adhesive based on silicone. Many people note that with its help it is very easy to install not only foam and polyurethane moldings, but also metal ones on a flat surface. Decorative panels are attached to porous walls or ceilings using liquid nails.

To make the whole process easy, and the end result amazing, it is important to consider their appearance when installing moldings. Flat panels are much easier to work with. It is enough just to cut the corners where necessary, and carefully glue.

When your panels have a figured appearance, you must first make a markup. To do this, attach the molding to the appropriate place and carefully trace it with a thin pencil line. Then glue the decorative elements clearly along the contour.

If we analyze the reviews of those who used moldings in their interior, it turns out that:

  • the most popular planks are foam and polyurethane;
  • for a budget price, you can easily create an interesting design, emphasize the advantages and hide surface imperfections;

Choose the right option and decorate your home the way you like!

First, let's give a definition of what a molding is. This is a fairly new, but already popular decoration with overhead strips and panels. With its help, you can align corners, hide defects, as well as decorate window and door openings, create a frame for paintings or other objects, as well as separate wallpaper.

A large number of positive reviews have been written about them, so before using a specific type, you need to have an idea of ​​the desired result.

To think that interior moldings are needed only for elegance is a misconception. They are often used to create an original look for window and door openings, framing wall niches, and ceilings. In large living rooms, they are also used in the decor of fireplaces. Due to the high decorative qualities, there are a huge variety of applications, it all depends on the needs and imagination of the owners. But we're going to talk about wallpaper separation moldings.

Types of moldings

Moldings for separating wallpaper, depending on the materials from which they are made, are divided into:

  • gypsum (most often it is stucco molding, which carries an independent decorative load, is attached with alabaster);
  • polyurethane, which can be used as a cheaper and lighter alternative to gypsum, after installation it is advisable to paint them (attached with acrylic glue);
  • wooden (installed with nails or glue, usually have the simplest forms, but there are also complex reliefs);
  • foam (mounted on walls with wallpaper glue, you can use PVA);
  • plastic and rubber (most often they have an adhesive layer and grooves for joining).

Wallpaper splitting options

In the presence of high ceilings in the room, a double ceiling molding line is often used. In this case, the wider one passes under the ceiling itself, some wallpapers are placed below (usually they use wallpapers that contrast with the main color of the room, but options using matching colors are also possible), limited by a narrower molding, and others are glued below, creating the main color of the interior. An example of wallpaper with molding in the interior is shown in the photo:

To create a relaxing, cozy and relaxing atmosphere in the bedroom, it is recommended to use wallpaper in calm tones that do not contrast with each other. To separate the boundaries between them, polyurethane moldings are perfect.

In large apartments, in addition to the ceiling separation, wallpaper is often highlighted with a molding frame on the wall. When creating such an interior, it is recommended to place lamps, mirrors, paintings, photographs, TV wall mounts, and other filling elements within the frames formed by the molding. Usually, the same wallpaper is placed in the frames. An example of dividing wallpaper in the interior in the photo below:

The division of wallpaper into sections limited by molding is used for large rooms. It looks most harmonious in the interior of studio apartments, if it is necessary to divide one large area into several zones. Thus, all zones can be distinguished with a different look, as well as the color of the wallpaper, giving the interior a unique character.

Quite often, the wallpaper is separated by molding when creating the interior of banquet halls, restaurants, living rooms and other places for relaxation.


For a classic interior, the use of painted or gilded moldings will give any room a unique look and style. For example, dark moldings will complement the interior, decorated in an oriental style.

Golden tones and light wallpaper as a background look great when decorating a room in a classic style.

Painted moldings should be used with care so that the interior does not look oversaturated, moreover, carefully select the wallpaper, they should be in harmony with the rest of the environment.

Installation of moldings

Most types of moldings have a protective film. It should not be removed before installation in order to preserve its decorative qualities and prevent damage. If heavy wallpaper is used, then it is impossible to glue even the lightest moldings on them. In extreme cases, they need to be additionally fastened with dowel-nails. An interesting division of combined wallpaper in the interior:

Before proceeding with the installation, it is necessary to carefully align the walls. It is much easier to mount decorative elements on flat surfaces. After that, it is necessary to carefully mark the installation sites. Installation of various types of moldings has some peculiarities.

Polyurethane, plastic and foam

At the end of the marking, the material is cut to the required dimensions using a hacksaw or jigsaw. The miter box will help to cut off the corner parts ideally. It is better to cut foam products with a clerical knife. All the cut parts are applied to the designated places on the wallpaper, the joining of the corners is checked (all corner parts must fit perfectly to each other), for this, when cutting them, it is worth leaving a small margin of 2-3 mm.

Installation should start from corners, this applies to both ceiling and wall parts. To achieve the best adhesion to wallpaper and wall, it is necessary to sand the flat sides of all the parts obtained.

Using a spatula, an adhesive is applied to the pre-treated surface of the molding and glued to the places of all elements.

When gluing heavy moldings to the wallpaper, it is worth pre-drilling holes for the dowel nails in the wall and the attached elements, this will prevent the glued areas from slipping under their own weight. It is not necessary to drill the foam parts - they can simply crumble.

After the glue dries, after about 6 hours, all joints and holes of the fasteners are putty.

If it was planned to highlight this interior detail with color, then painting should be done no earlier than a day after installation. It is imperative to take into account what the paint consists of, since some types can spoil the installed decor.

In addition, painting already installed panels is quite problematic, so this is done before mounting on the wall, otherwise the wallpaper can be damaged.

Gypsum

The most difficult material is gypsum. All parts are heavy, in addition, rather fragile, therefore, before proceeding with the installation, you must carefully check each for the presence of chips and cracks.

This material allows you to create beautiful, voluminous stucco molding, so it is used to create a rich interior. It is quite expensive, in addition, there are difficulties during installation, therefore it is not recommended to install it yourself, in order to avoid unnecessary costs in case of damage to the material.

Gypsum is extremely susceptible to moisture and therefore not suitable for damp rooms. The assembled parts of the molding are carefully adjusted to the installation site, for this they are sawn with a hacksaw. Then you need to make notches with a sharp tool (you can use a chisel), on the wall and the flat part of the elements to be installed. This is necessary for the best possible fixing to the wall.

Before diluting the glue, the surfaces to be glued must be moistened with water. Then gypsum is diluted (can be replaced with alabaster), to which a little wood glue is added (1-3% of the total glue). Using a brush, adhesive is evenly applied to the wall and the part and set in place. It is necessary to press the molding and move it a little along the wall, this will allow the glue to disperse evenly and provide a stronger adhesion.

You need to hold the part pressed until it grabs, then carefully, using a spatula, remove the glue that has protruded along the edges. At the end of the installation, allow 2-3 hours for the best glue to set. If desired, you can paint with acrylic paint. Gypsum moldings for dividing the wallpaper look very rich in the interior:

Wooden

Quite an expensive type of molding, usually used for fastening to wooden wall structures. When applying elements to the installation sites, they need to be cut to size.

Wood moldings are usually quite heavy, so when installing it is worth using not only glue, but also nails. Before installing in place, the flat surface is carefully coated with "liquid nails". Do not smear the glue too thickly, in order to avoid squeezing out excess during installation. Wooden moldings for separating wallpaper in the interior in the photo below:

Then the desired panel is pressed against the installation site and carefully nailed. The nail heads are bitten off and the nail shank is driven deeper and plastered. Installation on the already glued wallpaper is done in the same way, but when painting you should be careful, or paint them before installation.

Wooden moldings, especially from precious woods, are often coated with a colorless varnish that emphasizes the natural structure of the material and protects against moisture.

A short video will allow you to visually see the entire process of installing moldings:
