When finishing walls, we usually pay special attention to plinths. Outdoor plinths play an important role - cover the unaesthetic gap between the wall and floor or ceiling. Other decorations can be considered to help create a non-trivial, elegant decor. This task will fully help satisfy wall moldings.

In classic interiors

Moldings are primarily connected with the traditional design of palaces, residences of rich nobles. Today we can buy almost any decors with imitation of stucco, adapting them to the classic and modern interior design. They perform a magnificent baroque or cautious accent in the vintage style, will become a great way to emphasize the elegant classic nature of the interior. You can install them on:

walls of one color

Wall decoration with moldings - photo of classic interiors

Beautiful and light interior in a classic style with a fireplace in the foreground and an extra stripe on the wall provides a foundation for wallpapers with a classic, rich pattern. Moldings are thrive, classical stucco on the fireplace.

Wall elements can also cover the ceiling, forming a thin base. Light decor brighten dark, patterned wallpaper in classic style.

The decor will make the room with a cozy, elegant. In the classic interior, decorative shelves, pillars and portals, flexible moldings make up window and doorways over the passage to another room.

Especially relevant decors in the interior in Scandinavian style, on white walls, which without spectacular 3D decor look too boring.

Optical tricks

Moldings make it possible to improve the optical ratio of space proportions, so often appear among the latest interior design trends. This finish is not only fashionable, it will solve some problems.

Frames from moldings

Moldings offer many decorative possibilities. An interesting idea is to create a frame. Inside the frame you can:

stick the wallpaper contrasting color
cove the surface with patterned wallpaper.

The decoration of walls with decorative profiles may look spectacular - to act as imitation of a wooden trim, where, for example:

profile shape emphasizes the golden color of the wallpaper,
molding is used as a framework in which the picture is placed, fragment of decorative wallpaper.

Sometimes they create complex compositions covering the entire wall and more modest, almost minimalistic corresponding to modern interiors.

Decorative strips throughout the wall

Molding can cover the entire wall, forming rhythmic divisions using:

metal profiles
moldings made of plaster, polystyrene foam, covered with golden paint.

In the photo of the room presented below, the designers created a complex composition based on the contrast of colors, a game of light. Dark, cold shade of gray - excellent background for golden profiles. With such a layout, the profile form is emphasized optically. Thanks to the addition of gold, the molding glitters, "catches" the light will emphasize the geometry of the wall fragments.

The decor of the room will emphasize the chandelier, made in golden color as profiles, and a writing desk. Furniture items merge with the environment. This example shows how with the help of a successful selection of furniture, accessories create a stylistic coherent mechanism.

Wall with decorative painting elements

A thin decorative molding can be part of the composition introducing into the interior part of decorative painting. The room shown in the photo below is used fine floral motif, which, in combination with pastel color, is very delicate, without imposing the decoration, which will be the background for any interior room. Wallpapers are framed by thin profile racks painted in the color of the walls.

Another example represents the interior in a strict, modest style. One wall is emphasized by wallpaper in the frame of thin white wall moldings from polystyrene foam. Adding a simple decorative frame emphasized the decorative character of the wallpaper. This procedure allows the wallpaper fragment to act as a widescreen image. In the presented interior, it is the wallpapers that are the main, dominant color accent. Furniture, accessories are represented only by addition.

Wall-mounted composition of moldings and wallpaper

In the next embodiment, the motive on the wallpaper does not dominate the interior. The composition of moldings and wallpaper becomes a strong accent, which serves as a starting point of the game with a shape, color. Here I interact 4 elements:

form of field frames arising from the developed divisions;
wallpaper pattern;
wallpaper colors;
color frames.

As in the previous example, furniture and additives in color, form interact with the wall style.

Wallpaper

In the following embodiment, the wallpapers are the main element of the composition, the profiles are only decoratively framed them. In the photo below the wallpaper with a golden brilliant pattern decorate the wall with flicker. The pattern not only decorates, but also with the correct intensity of light illuminates the interior.

Decorative frame from the headboard bed

Another example allows you to highlight the recreation area in the bedroom, emphasizing the headboard bed. Here framing profiles are designed to limit the contour of the bed. Filling a symbolically marked headrest is performed from:

fabrics
paints,
wallpaper.

Framing of the wall clearly repeats the size of the bed, emphasizing the composite design of the designer.

Decorative frame as background for furniture

Insert with decorative wallpaper can emphasize a certain element of furniture:

spectacular chest;
decorative fireplace;
home library;
exposure of photos;
aquarium;
wall per TV.

In the photo presented below, yellow supplements that are harmony with the color of the walls, with the introduction of gray tones overlap, are well exposed. This option will be a real highlight in the modern interior.

Conclusion

After ascetic minimalism, the time occurs when those who want to play with forms, colors appear. Bold researchers for help come forgotten wall decorations, resembling plaster. Stucco and wall ornaments performed by plaster on the surface of the walls, the ceilings until recently tied only with palace interiors or low-quality fakes. These palace wall decorations give the interior elegant nature, can optically increase the space.

The stucco knew the ancient Greeks, Romans. She repeated the shape of the bearing elements of buildings (columns, spiers, eaves, beams), creating decorative organic and geometric motifs. They were reopened in the XV century, thanks to the discoveries in the Roman residence of Emperor Nero. A rich sculpture decor in the interior and the facades was especially popular in the baroque era, the plaster has gained great popularity. Light elements from stucco successfully replaced expensive stone sculptures.

Today, moldings in compositions with wallpaper allow you to create modern artistic forms. They are produced from plaster, wood, polystyrene foam, artificial marble. This wall decoration is returned to fashionable living rooms, decorated in different styles, creating interesting optical effects, wealth of forms, patterns. Regardless of the style of the interior, everyone can choose the finish option, from the simplest modernist to a rich flower decor.

Monophonic and empty walls without unnecessary pictorial elements are a universal version of the design, but for creative personalities there is not enough such interior. Then wall moldings come to the rescue - overhead decorative panels.

Multifier forms, widths, lengths, manufacturing material makes such a decoration in demand and modern. The main thing is to know where, when and how to use it.

Briefly about element

Registration of walls with moldings includes frames, plinth, corrugated planks, panels and stucco. Among their functions are not only aesthetic, but also other points:

Masking defects of the wall surface, flaws and irregularities;
Separation of space for individual sections;
Separation of some wallpapers from others;
Decoration of window and doorways, niches and arches;
The creation of "fake" windows;
Use as plinths to hide the knocks between the wall and floor or ceiling.

Some decorators expand the scope of the framework and decorate their furniture, make out sockets and switches to fully create a conservative atmosphere of real classicism.

Types of decor

Depending on the style of the decorative, the height of the ceilings is selected with certain decorative moldings. So, there are convex, concave and flat models.

The convex panels with stucco, protruding ornaments and clearly dedicated frames are often selected for classical and historical interiors. Volume is also attached due to spraying, overhead elements.

Simple direct are more suitable for minimalistic designs, while preference is given to neutral shades or stylized natural wood.

Went models are a simple dye with convex edges that create an illusion of in-depth space. They are considered universal and are suitable for designing any rooms.

Panels and by manufacturing material, which can be played as:
Plastic (the most budget option, has a wide color gamut and low strength);
Foam (ease and high degree of wear);
Tree (noble natural texture, distinguished high quality and price);
Marble or other stone (expensive durable material, requiring special care and reliable fastening);
Polystyrene (it has resistance to sharp differences of humidity and temperature);
Gypsum, plasterboard (only in white shade or in ivory, durable and inexpensive);
Polyurethane (the environmental friendliness of the material does not absorb the smell and moisture, resistant to differentials and painting, elastic and practically no deformation).

Each material has its advantages and disadvantages that need to be interested in sellers of consultants or decorators. The latter will also prompt some useful tricks: in wooden panels you can cut the grooves for electrical wiring and apply the original thread or painting.

Ideas for design

The rapid transformation of the existing interior will help slight decoration of surfaces, openings, walls and furniture with moldings. Thus, interior doors or arches can be visually expanded, putting the planks around the perimeter and paint into its corresponding color.

For a visual increase in the height of the ceiling and, accordingly, the square meters of a small-sized apartment applies the following method: two parallel straight straight with a period of 3-5 cm glued to the wall under the ceiling.

On the walls, the use of various zoning with decorative elements is the most wide and non-standard. For example, a lower finish is separated from the upper wallpaper, special "fake" windows are highlighted or photographs, pictures, paintings, posters and other wall-mounted compositions.

Also, in addition to decorating, Moldings are used as multifunctional items: holders for shoes, shelves for books and magazines, stands for photos and accessories, an alarm clock platform or a frame framing for a television panel.

In any case, it is necessary to take care of the harmonious fitting of the decor in the interior and on reliable fastening it to the base.

An excellent and unusual solution will be the transformation of the old furniture, the masking of some surface defects and the facades protection of sharp corners and the attachment of the upholstery.

Methods of fastening

Mounting most panels simple and does not require special skill and effort. The main thing is that the surface is smooth, clean and dry.

The method of fastening the wall on the wall directly depends on the material of the manufacture: screwing with self-draws or gluing with a special solution. Relevant information is found at the purchase stage.

Some models are self-adhesive and have a special layer covered with a protective film. During repair, protection is removed, and the panel is applied to the desired place.

If the adhesive base is not provided, then for plaster, polyurethane, foam, plastic and polystyrene models, a polyurethane gel is additionally acquired, which reliably fixes and leaves no traces on the surface. Heavy wood panels require more reliable mounting: self-drawing, nails, scrapers.

Designer secrets

Photos of moldings, figurine on the walls, attract attention, prompting to repeat the idea in their interior. But only subject to certain rules, you can achieve a clear figure and an ideal end result:

The intricate pattern requires preliminary design on the surface of the prompts by construction pencil;

Visually will increase the space of snow-white panels;
Frames and plinths must be maintained immediately in several places of the room;
The spacious rooms are appropriate massive, wide and convex models, and only narrow and direct options can be used on small-sized areas.

The width of the bar can reach 10 cm or more. What molding in the interior preferred and how do they place the room?

Material for molding

If a similar type of decor was made only from the gypsum, now there are quite a lot of materials for planks, characterized by price and properties. So distinguish decorative strips from such materials:

Foamflast. The easiest and budget option. One of the advantages is the ease and simplicity of installation. Foam moldings in the interior are found on the walls and ceilings, have a different width and pattern. The disadvantage of such a plank is its nonstopness to mechanical damage.
Polyurethane. Durable enough to use on walls or furniture, there are even flexible strips, which are just convenient to decorate columns. Polyurethane moldings are more expensive than foam, but cheaper than the following types. Moisture-resistant, which allows them to be used in bathrooms and kitchens.
Wooden or MDF. The environmentally friendly view of the element is quite cheap, but has one minus - instability to moisture.
Gypsum, marble, metal. Not too popular species of moldings, differ in high price and complexity of installation. Mainly used for the design of facades or interiors of expensive elite houses in the classic style.

The most popular today are foam and polyurethane decorative planks for the interior of apartments - they are light both in terms of weight and installation, budget and weigh a little.

There is another type of this type of decor - self-adhesive. Make it most often from rubber or plastic. This molding is used more often as borders for bathrooms, easy to install and does not require special knowledge and skills.

What do moldings apply in the apartment

Moldings are used not only for classic interiors or provence. Depending on the pattern, there are even interiors in the Scandinavian minimalism or in the style of Hi-tech. The main thing is to know where and how to use them.

The most popular type of application is the design of the junctions between various details of the finish. For example, between different wallpaper, between wallpaper and tiles, between the wall and the door frame (as platbands). In the same way, you can disguise the errors of the finish.

One of the popular ways to use decorative slats can be called design of door or arched openings. For the latter there are special flexible moldings, which also draw up the area around the arches.

By the way, the fact that in common people is called plinths - is also a type of molding, which is designed to mask jointers between the wall and floor or ceiling. In the case of floor plinths, it is better to choose hard material, such as wood, MDF or plastic. But for ceiling plinths fit foams.

So, where moldings are used:

for the design of joints of different finishing materials;
for the design of the columns and arches, for this use flexible polyurethane elements;
to highlight objects that deserve attention (for example, frescoes, panels or photo wallpapers);
for design windows and doorways;
for various decorations on furniture, ceiling and walls;
for separating the upper and lower part of the wall (panel design);
for masking uneven joints, both ceiling and walls and two walls or corners;
to protect against abrasion in places of frequent touch of door handles or furniture items.

Moldings on the walls in the interior can perform both decorative function and practical. As decorative elements, the planks are used in classical interiors for separating the upper part of the wall and lower, for the design of the so-called "panels". Also decorative straps allocate some kind of area on a wall that deserves attention. It can be a photo wallpaper or fresco, or a wall fragment, the originally rearranged.

Moldings are particularly popular for the separation of wallpaper. The principle of this method is that the joint is not visible between different wallpaper. It turns out a part of the wall, which is placed by another type of wallpaper, as if "in the frame".

Special attention deserves the practical use of decorative slats. Durable wooden or polyurethane elements protruding from the wall of about 2-3 cm serve some protection against mechanical exposure to door handles or furniture items. In addition, you can attach a decorative bar on the wall in those places that are subject to rapid pollution.

Moldings in the bedroom interior

Also, decorative strips allow you to create a contrast pattern on the wall, while you can use semicircular and round elements, all kinds of sockets and curly patterns sold separately.

Another original solution to the use of moldings is to decorate the window opening. In this case, the planks create the impression of the window to continue, expanding it and perform the role of decorative platbands.

Ceiling moldings are used not only to mask uneven jacks between the ceiling and wall (ceiling plinth), but also for the original ceiling decor.

Smooth ceilings gradually go into the past, multi-level structures come to their place, with original design.

Moldings on the ceiling can perform the role of the separator of two materials, such as wallpaper and paint. The intricate patterns used in the classic interior are easily laid out of ceiling decorative elements. But the ceiling planks can be used in modern interiors, if the form of them will be straight and not intricate.

The original solution will combine two types of coatings, such as ceiling tiles and painting. From the ceiling tile you can post a rectangle or square and framed with a decorative plank.

For ceilings, foam elements are often chosen, since they are easier and do not cause difficulties in the installation.

Since the main task of moldings is the decor of the room and interior items, then it is necessary to mount it carefully, so as not to damage the bar and do not leave any traces on it. For fastening, special silicone-based adhesive are most often used.

If the surface of the wall is porous or not quite smooth, then liquid nails can be used for mounting.

When used as a decor of figured slats, they first need to be placed: putting to the desired location, put in a pencil and glue strictly along the line.
