Many tenants small apartments they dream of spacious rooms, but sometimes it is simply not possible to acquire them. However, you can try to correct the situation, which is called "on the spot." Namely, competently make repairs in a small room in such a way as to visually increase its size, while the correct layout of a small room will help to use the space as efficiently as possible.
Of course, on an area of 10 square meters (and sometimes less) it is quite difficult to place a living room, bedroom, work and / or children's corner. Such a task is sometimes impossible even for professional designers. But here it is quite possible to “squeeze all the juices” out of a small room for the improvement of a living space, creating comfort and coziness in it. It is necessary to know only a few rules, and in some matters and tricks, when carrying out repairs of a “small scale”.
Color design
Designers recommend using light shades for decoration when repairing. You can apply a cold line of colors, such as light green, light blue, light gray, pastels and others. In this case, the focus of the color optical illusion will work. Such colors, as it were, visually move away from the wall or ceiling that enters the room, decorated in such colors.
It is not forbidden to use warm shades: red, yellow, orange, peach, etc. but at the same time they should not be too saturated, otherwise you can easily achieve the opposite effect. Staying in such a room will become psychologically uncomfortable due to the feeling of constant pressure from the walls or ceiling.
The most optimal color scheme for a small room will be monochrome when choosing colors in the interior. It's not just about shades. finishing materials, but also when choosing the color of curtains, furniture, textiles and other design elements.
Light in the room
If there are limitations when choosing a color scheme, then there are many lighting options. The exception is a large chandelier, which will automatically “steal” half of the ceiling. For registration, it is preferable to choose Spotlights small diameter. The main thing when choosing the geometry of their location is to take into account light accents over individual areas of the room. It is also not recommended to load the ceiling surface with a large number of light points, otherwise you can mistakenly achieve the effect of one continuous chandelier. Better add lighting wall sconces, a floor lamp or a small floor lamp.

We decorate the ceiling
The interior of a small room does not involve the use of any large, even "protruding" design elements. This unquestionably applies to the ceiling.
You should not use multi-level structures, even if the ceiling height is suitable for this. The fact is that multilevel ceiling will attract undue attention to itself, thereby creating the impression of overhanging and pressure. But if, nevertheless, it was decided to install just such a ceiling, then its wide or too long elements should be avoided. Because a too voluminous cascade of elements of the ceiling structure will not only visually expand the space, but, on the contrary, will visually turn the living room into a “matchbox”.
To decorate the ceiling surface, it is better to use PVC film, in other words, stretch ceiling, while using light shades, ideally - classic White color. But regardless of the color of the film, according to the texture, it should be glossy, not matte. This will additionally "stretch" the room in height.
By the way, most people feel calm and secure in a beige and white interior. The fact is that a couple of decades ago, astronomers studied about two hundred galaxies and deduced ... the average galactic color. It turns out that our universe is beige and white.
Making the floor
Many owners of small rooms do not pay enough attention to finishing the floor, explaining this by the fact that in a small room, few people "look under their feet." However, this is not entirely true statement. Of course, you should not use materials that are dark or heavy in texture for decoration, it is better to replace them with something “light, light and uniform”. At the same time, if flooring has a pattern, then it is advisable to place it diagonally, which will visually increase the area of \u200b\u200bthe room.
There is another trick. The floor in a small room can become a source of heat. It is the installation of a warm floor that will allow you to get rid of the heating radiator, which in turn will free up part of the space under the window, which can be used differently.
Small room decor
To furnish a small room, choose compact furniture. This will help save space. There are several design tricks to help answer the question: “How to furnish a small room?”:
For example, a sliding wardrobe will free up valuable meters that would be required to open the doors of an ordinary wardrobe closet.
A transforming bed can easily turn into a comfortable sofa or an equally comfortable table or cabinet.
You can also use "multi-story" furniture: a bunk bed will significantly free up space in a small nursery.
Furniture cladding elements should have a light texture, preferably glossy, mirror, glass or transparent plastic.
In general, furniture should be kept as small as possible. In this case, you should pay more attention to its functionality than aesthetics.

Interior nuances
When making a window in a small room, you should remember about sheer curtains from light materials (textiles, tulle, chiffon, etc.) in the color of the walls. Then it will seem that the window merges with the walls, which will enhance the sense of space. In no case should you use hanging elements such as, for example, a lambrequin. Perfect fit roller blinds, which will free the window opening as much as possible.
When choosing all kinds of accessories, you should simply show asceticism. Because figurines, photos, vases and souvenirs, placed wherever possible, will not only not decorate the room, but, on the contrary, will create a feeling of congestion and clutter.
Strictly speaking, the chosen style of a small room should be as close to Japanese as possible. Scandinavian style or, ideally, to minimalism.
By observing and applying these simple rules when repairing and creating an interior, you can easily get rid of the stereotype that a small room is a busy and poorly adapted room for living. Even the smallest room can be turned from a "closet" into a comfortable and cozy "nest".

How to equip a small room so that it is not only beautiful, but also fully functional? The implementation of the design of a small room with a photo of 2016 and modern ideas, options for repair and arrangement are set out in this article. We hope that at least some of the tips and ideas will help you find the solution that suits your style and character of the interior.
Small room - renovation and design ideas
It can be difficult to arrange an aesthetic and functional interior in a small living room or bedroom. It is difficult to plan a small living space that is not only eye-catching but also fully functional. Most of us face this problem because the apartments we live in are not very big in most cases. AT last years, the living rooms combined with the kitchen have become fashionable, which further reduces the footage intended exclusively for the recreation area. In fact, this is not so bad, but it is difficult to plan such a small area on your own in such a way as to fully satisfy the requirements of functionality and aesthetics. Especially as awareness of the role of good design in Everyday life, thus creating a need for attractive housing and fully usable space.
About how to equip small rooms, ideas from photos of various interior designers are collected in our gallery and are presented below. Some of them with a kitchenette, others with a kitchen and a dining area form a single living space. Even small rooms can be decorated in various styles and flowers, and each square meter should be carefully considered and used.
A small living room, if well designed, will appear larger than it really is. Guests will ask you about the size of the room, and they won't believe that the room is that small. If you're wondering how to decorate a small room, remember that everything matters - furniture, accessories, colors and lighting. What should be remembered when renovating a small room? First of all, we must try to extract the maximum space from a small room. There are some general principles, which can be used, but not necessarily all and not always at the same time.
To make the ceiling seem higher, it must be painted white, it can be bordered by a wide ceiling plinth, which will separate the ceiling from the slightly darker walls.
Organize the space by removing unnecessary elements. Cabinets, shelves, and other storage systems (in wall recesses, under a bed, or under windows) make this task easier. In a small living room, only the necessary elements should be left in plain sight. Jewelry should be kept in the same style and used sparingly. So, for example, the room in the photo below is decorated in a cozy beige. The main decorative element here is dandelion-themed photo wallpapers that visually expand the space. Cabinets, which are almost invisible, merge with the ceiling to form a large single space.
Upholstered furniture it is better to choose in pastel light colors, then it will not overload the interior, visually reducing it. The minimalistic shapes and light colors of the sofa and armchairs will look perfect in a small space.
The rule of thumb when decorating a small living room is: the lower the furniture, the higher the interior appears. Low furniture is visually able to expand the perspective. Tall and wide bookcases should be placed against a short wall - thanks to this, a small room will have better proportions. Or you can create a "frame" of furniture: put high cabinets on the sides, and low cabinets in the middle. It would be nice to place cabinets not opposite the entrance to the living room. Furnishing a small room, do not forget about the corner furniture options. If you have a small living room, it is advisable to choose multifunctional, folding furniture:
- folding tables;
- pouffes, sofas and armchairs with storage containers;
- tables with drawers;
- chairs that can be compactly folded and put away after the guests have left.
This way you can save a lot of space.
Furniture should not overwhelm the interior of a small room. It is better to choose options that transmit or reflect light and do not block the view. If you have a small room, it is advisable to choose the following facades:
- glass, just remember that transparent glass requires maintaining order in the cabinets;
- frosted glass facades can be an alternative, which veil the contents of the cabinets;
- colored facades;
- glossy surfaces.
Well-chosen furniture will allow you to effectively use every meter. Smooth and glossy practical shelves will be functional and beautifully decorate the interior without overloading it. Usage large mirrors visually doubles the space.
Are you looking for a place in the living room for a tall cabinet? The corner of the room will do. If you install a cabinet in a niche and make it a facade of decorative glass, this piece of furniture will imitate the door to the second room. In a small room, you should not put massive, rich pieces of furniture, because they take up a lot of space and absorb light. Openwork furniture or transparent chairs, tables and shelves, chairs with thin legs are best suited.
Massive, full and heavier furniture will become less noticeable if it has a shade similar to the floor in the living room. Tall cabinets should not dominate the interior. It is better that they merge with the background, for example, with a wall. Both walls and furniture should have light shades, and cabinet fronts should be smooth, devoid of massive decorative handles.
Doors and floors in a small room
If you have a small living room, doors and floors should provide a backdrop that won't draw too much attention. It is better to choose smooth doors, without decors. Lacquered doors are welcome, with glazing elements or a glued mirror. In a small room, the floors are better to choose light, monochrome, reflecting light.
Instead of one door, you can put a double door, for example, with glass wings, which can be wide open or put a sliding system. Roller sliding doors can be hidden in the wall, you can slide the wings along the wall and hide them in a specially built box.
High white skirting boards will look good on the floor, thanks to them you will optically move the boundaries of the floor. When paired with darker walls such as grey, you can create an impressive contrast and the illusion of depth on the wall.
When purchasing floor tiles, choose large formats (60x60 cm, 90x30 cm) and a smooth surface. The fewer visible seams, the smoother and larger the floor will appear. If the floor is wooden or imitating wood, then it is good that the material also creates a uniform surface (without pronounced texture, color differences, etc.).
If you are furnishing a small room, of course, light-colored walls will be the most suitable. But you can paint one of them in a stronger tone. The basic rule is to maintain color consistency in the interior of a small living room.
Using white as the main color allows you to create a background for other colors, beautifully display furniture and accessories.
If the whole studio is furnished in white, it will look very bright and spacious, a few bright accents will give liveliness to the minimalist interior and will attract attention. If you think snow white is too boring, break it down with pastels or in gray. By juggling two or three shades from the same palette, you can get the illusion of spaciousness in a small living room.
Do you want to paint one wall darker or darker? bright color? Great idea! Red will raise the temperature of the interior, make it brighter, gray and brown will add calmness, which will add warmth to the atmosphere. One wall of the room, painted in a more saturated color, will “move away” from us and create a sense of depth, helping to create visually better proportions in a small living room.
Of course, the already existing dimensions of the apartment cannot be corrected, but by making repairs in a small bedroom, taking into account original design solutions and techniques, you can get a cozy and functional space even in small room. Now we will share with you design secrets for the repair and arrangement of small bedrooms.
Planning and creating a design project
It is necessary to carefully consider the design of the project, which will display your vision of the room after the work is completed. Repairing a small bedroom involves the exact location of the necessary items. So what to consider:
- the location of the bed, which is the main element;
- location of the wardrobe for linen and clothes;
- options for placing bedside tables, chest of drawers, shelves, etc.;
- the location of the chandelier, wall lamps;
- think over options with curtains and other decorative elements of a small bedroom.
It is better to sketch on paper, or you can use a modern computer program. When thinking about design issues, it is necessary to take into account the footage of the room and its type - square, rectangular, narrow, etc.
Square bedroom layout option
Rectangular bedroom layout option
Examples of the layout of an elongated narrow bedroom
Most often, a bedroom is a room designed for rest and sleep, but sometimes it is masterfully equipped with a wardrobe or working area. All these points are worth thinking about at the stage of interior planning in a small bedroom.
By the way, you can learn about how to make a dressing room in the bedroom by reading.
wall decoration
In the room country house can be used to repair walls wood material or decorative plaster. This technique will give volume to the room, visually make it more spacious.
In the apartment, the most suitable option would be wallpaper, which will provide a favorable microclimate for residents. Ordinary paper trellis, non-woven or textile will do.
About that, we wrote here.
Ceiling
AT modern designs glossy stretch ceilings help to increase the space. Here the main task is right choice shade.
Another one fashion trend– coffered ceiling with mirror elements.
Floor
The floor in a small room is better to make light. The ideal option for the interior in a small bedroom is parquet or laminate. It is better to install the material diagonally, which in itself will serve as an extension of the interior. You can decorate the floor with a carpet to match the furniture.
doors
When choosing doors, do not forget that they should be close to the color of the floor or baseboard. You can adjust to the color of the bedroom decor, which will create a harmony of all accessories. For a small room, sliding or swivel mechanisms are suitable, which significantly save space.
How to choose wallpaper for a small bedroom
Successful repairs in a small bedroom will directly depend on the wallpaper selected for this purpose. Among the large number of tricks, there are several basic rules for wall design with wallpaper, in accordance with the type of room.
- In a room with low ceilings, it is worth giving preference light wallpaper with a vertical pattern. It is better not to use a wide border, as this will make the room even lower. If the ceilings are high, then it is better to step back from the edge of about 15 cm. This will help make the room more proportional.
- If the bedroom is small and dark, you can beat it with a warm yellow. At the same time, the wall, which is illuminated the worst, can be pasted over with stripes of wallpaper in a lighter shade. This trick will help visually stretch the square room.
- Using different wallpapers in the same room. Thanks to this option of visual adjustment of space, it is possible to designate areas intended for rest or work. It should be remembered that the wallpaper must have General characteristics, manifested in texture, pattern or shade.
- You can significantly revive the interior of a small room with the help of photo wallpapers. It is better to give your preference to 3d-images that imitate a space that goes deep into. It can be a path between trees, the sea or spectacular skyscrapers. Modern wallpaper with a realistic 3d effect will definitely become original solution for the room, slightly adjusting its dimensions.
We talked in more detail about the choice of wallpaper in a small bedroom.
Secrets of interior design in a small bedroom
The choice should be made in favor of favorable bright interior which affects visual perception. Not everyone likes an all-white or beige room. In this case, you should use bright accents. Pick up textiles of your favorite shade, get a bright and extraordinary lamp on the bedside table.
To shift attention from small space, you can hang a large picture, which will become the main focusing element.
In the design of a small bedroom, along with the importance of color, light also plays important role, so you should choose good lighting. First of all, it is worth paying attention to the main sources of light - windows. Remove everything that can clutter them, remove curtains that are too thick and replace them with lighter and more compact ones. A good alternative here would be light linen curtains or an option such as Roman blinds.
A chandelier for a small bedroom will serve as a source of light in the dark. It can be a few small lamps on the ceiling, the light of which is directed upwards. They will help raise the ceiling and make the bedroom more spacious. In a small room, you can use compact bedside lamps, hidden lighting.
In the visual expansion of space, the mirror plays an important role. It can be attached to a wall or closet. Several mirrors are able to break up the space, thereby expanding it. Sometimes the design does not involve the use of mirrors on the walls. In this case, you can use various mirror surfaces of furniture, for example, a dressing table, dressing table, etc.
Also in the interior there may be glass elements in the furniture, which will not clutter up the space due to their lightness and transparency.
Furniture for a small bedroom
Small rooms do not have a large space resource, so it is necessary to approach the selection of storage systems with special attention focusing on compactness and functionality.
A standard bedroom set for a small room will not be entirely relevant. In addition, it is not always fully used. It is better to replace cabinets with shelving or use special wall shelves without visible fastening.
For the correct arrangement of elements, you need to try to avoid voids. There should be a minimum number of things, but always involved. A large number of things, books and other items will only interfere with your relaxation and good rest.
Read about the arrangement of furniture in the bedroom.
The bed can be used not only for its intended purpose, but also become a kind of pencil case with storage boxes without a massive headboard. The best option can be considered a bed-transformer - a folding sofa or bed with a podium in which you can store things.
If desired, you can put the bed diagonally, unless of course the front door allows.
A bed with drawers is a great option for small bedrooms.
In a room with low ceilings, you should pay attention to the options for beds in Japanese style where a low platform makes the room more spacious.
Sometimes bunk options or loft beds are appropriate, which are equipped with shelves and drawers. Thanks to such products, you can properly dispose of precious meters.
In order for the bedroom to be half as well as a study, you can use several pieces of furniture: a table, a chair, appliances. It is important to correctly distribute the space.
Good idea to do workplace, turning the window sill into a countertop.
The surface of the window sill can act as a table, unless of course its width allows, or you can use the folding mechanism. A rack fixed on the wall will help to significantly save space and organize a small but functional work area.
For a small bedroom built-in or corner cupboard the same tone with the walls will be the most rational choice. If the quadrature allows, it is advisable to give preference to a wardrobe with mirrored doors. This would be very suitable for modern interior small room.
It is necessary to carefully consider the options for filling the cabinet. There should be shelves and hangers that will help accommodate the maximum number of things.
A design move will look very original in such a room, where the bed is placed on a kind of illuminated podium, to which a work surface and a cabinet are attached. As a result, the effect of lightness is obtained due to the sleeping place “hanging” in the air.
Based on the material described above, we can conclude that the modern implementation of repairs in a small bedroom, as well as the numerous techniques that we have told you about, will help to visually enlarge the space and use it as competently as possible. You only need to adapt the solutions to your housing option and improve the idea to get an original and stylish design.
A worthy place among the many building materials is occupied by semi-dry pressed brick. Understanding all the advantages and disadvantages of a particular material, it is possible to optimize the construction process, reducing the total cost without losing quality. Due to the availability of raw materials and the simplicity of production technology, you can make ceramic bricks with your own hands.
Advantages and disadvantages of semi-dry pressing brick
The advantage of manufacturing products by semi-dry pressing is:
- Lower cost. This indicator is affected by cost savings:
- For electricity and gas for drying. As a rule, raw brick has a low moisture content due to the use of low-plastic clay press powders, so the pre-drying time is significantly reduced. More often this technological stage is skipped, then it is a “dry pressed brick”.
- For labor costs. In view of the exclusion of the stage of shifting from drying to firing trolleys. Raw is placed immediately in the oven.
- For the purchase of raw materials. For production, the use of leaner, and, accordingly, cheaper clays is recommended.
- Products are of high quality, right angles and perfectly even edges and edges.
- High production speed.
- Good thermal conductivity, strength.
- Variety of color palette.
The disadvantages of the semi-dry pressing method include:
Full-bodied material is quite heavy.
- Increased gas and water permeability due to the low density of the product compared to plastic molded products.
- Lower frost resistance.
- Relatively large weight of a full-bodied product. The creation of a hollow brick is possible, but difficult due to the flowability of the starting material.
What to do?
Semi-dry pressing brick is made from special highly concentrated dispersed clay systems with the following properties:
- Lack of coherence, flowability.
- Uniformly fine granule composition.
- Humidity 9-12%.
- Compressibility of the powder.
Methods for making clay substances
Drying and grinding production of ceramic bricks consists of the following stages:
Raw materials are crushed using a special disintegrator.
- Crushing on rollers. A basket-type disintegrator of the SMK 211 type is used.
- Tumble dry at 600 to 800 °C. In airmobile mills, crushing and drying processes can be combined.
- Sifting through string, swinging or vibrating sieves, drum screens.
- Humidification is best done with steam, but it can also be done with finely dispersed water with constant stirring. Further, the clay is sent to the bunker, where it rests for 24-30 hours.
With the slip method of production, the raw material is more uniform and equally moistened, practically does not contain dust, all the granules are uniform and small, air is easily removed during the pressing process, the product is pressed more densely and efficiently without increasing the pressure force. The slip method involves the passage of the following stages:
- clay dissolution hot water in a clay pot. Humidity should be brought to 40-45%.
- Pumping and cleaning under pressure through arc screens.
- Draining the mixture into open sludge pools for mixing.
- Transfer to a spray dryer, where the clay is finally brought to a moisture content of 10%.
Production and necessary equipment
The powder, by compression at 15-40 megapascals, is molded into a dry-pressed brick. Presses like SMK 491, 503 are often used in production. Compression technology is divided into 3 stages:
Using the SMK-503 press, clay is molded into a finished product.
- Partial extraction of air from the clay mixture.
- Compaction, during which all the moisture from the deep layers of clay grains is squeezed out onto their outer surface, which provides a better grip.
- Finishing, in which the pressed product receives maximum compression and internal adhesion due to the strong development of contact surfaces.
For any powder there is a boundary pressure, exceeding which no longer gives any additional compaction. Pressing modes can be:
- percussion and smooth;
- unilateral and bilateral directions of efforts.
Drying, if necessary, is carried out in tunnel dryers, placing bricks on kiln cars. Drying time - 20-25 hours at a temperature of 120-150 ° to a humidity of 4-6%. Firing is similar to spot welding. This explains the decrease in the compressive-bending strength of such products. A good alternative to a tunnel oven would be an annular oven with removable vaults to reduce the cost of brick production. Before firing, it is necessary to load 400 pieces of products at once through the vaults without using trolleys. Such furnaces consume less electricity and gas. The construction of an annular furnace is 2-3 times cheaper than the construction of a tunnel furnace.
Raising the temperature to 1200 °C and firing time will help to avoid excessive brittleness.
The original facade of the building is the dream of owners with good taste. For this purpose, it is necessary to choose high-quality and often decorative building materials. Hyper-pressed brick is one of them. By its properties, it differs little from natural stone, and outwardly it has enough variety to embody the most daring and original design solutions.
The brick created by the new technology has the best performance than the analogue obtained by firing:
- strength ranges from 100 to 400 kg / cm2, depending on the brand;
- density - up to 2200 kg / m3;
- thermal conductivity up to 1.0 W/(m °C);
- water absorption - 6-7%;
- strength grades up to F300;
- not combustible;
- can be applied to buildings of any height.
The types of products are as follows:
- ordinary - smooth;
- facing - angular, narrow, figured and spoon decorated under a stone.
Just like clay, it can be full-bodied and hollow.
There is also the so-called Lego-brick, which is assembled with the help of grooves and does not require mortar - you can simply lay it on building glue. It is distinguished by a slightly lower density - 1,600 kg / m3 and durability - applicable up to 150 freeze and thaw cycles.
Manufacturing technology
To its properties facing brick owes to hyperpressing, a method in which finely dispersed moistened construction material formed under high pressure, resulting in cohesion - the adhesion of particles at the molecular level. In fact, it is cold welding.
The technological process is complicated - special equipment is needed for the production of hyperpressed bricks. It includes crushers, presses, dispensers, mortar mixers, conveyors, screens, two-arm chutes.
As the main material for the product are suitable:
- limestone;
- sand;
- crushed granite;
- marble chips;
- battle of ceramic bricks;
- iron ores;
- enriched coal;
- blast furnace slag.
In addition, water and an adhesive mortar - concrete or lime - are used.
After pressing, the finished brick matures in a steaming chamber at a temperature of 70 ° C for 3 days, gaining strength. The final shape - the surface in the form of chips - is given to it after this procedure. If it is possible to lay "fresh" brick in warm weather, then it is able to ripen for another month, becoming stronger.
Application
Hyper-pressed facing brick is used for construction and decoration bearing walls, columns, decoration of the plinth, arbors, facade, installation of fences, borders, elements landscape design. Private - used for the construction of the foundation, garden paths, car parking spaces.
Advantages
The non-firing hyperpressed brick has a long service life, it can serve up to 200 years, while maintaining an aesthetic appearance. It is used in any climatic conditions, as it does not absorb moisture and does not collapse under the influence of heat or frost. He has good soundproof properties. When using hyper-pressed brick, reliable structures are obtained that do not require maintenance, so it can be placed in areas of increased seismic activity. It will not collapse from the blast wave.
Masonry is lightweight, as its dimensions are very accurate, like that of silicate. Yes, and adhesion to concrete is carried out better than with other types of bricks, which saves mortar when laying. In addition, it is available in a variety of color scheme, which allows you to create a unique architecture. And the calculation of the project using this product is obtained with the smallest error, so you can save on the purchase.
Flaws
The price of hyper-pressed decorative brick is twice as high as usual. But even if the funds allow you to make a multi-storey cottage, you should not forget that the full-bodied material gives a big load on the foundation, as it is as heavy as a granite stone. For the same reason, it is not advisable to use it as interior partitions, especially in multi-storey buildings.
Average prices in Moscow
You can buy a hyper-pressed Lego brick at a price of 11 rubles / piece.
DIY styling
First you need to check and adjust the surface of the plinth using a level. Then prepare cement-sand mortar, which should not contain large fractions. It is better to do batches in portions, as needed, and it is advisable to prepare the gluing material itself sufficiently dense.
Laying a hyper-pressed solid brick with your own hands will differ little from a professional one if you use river sand for mortar, high-grade cement - from M 500, good equipment - a concrete mixer, and be careful during construction, carefully removing accidental contamination immediately.
And most importantly, make the first row well, starting to align the blocks from the corners. The next rows are laid with an offset. It is important to check each level with a thread, avoiding the slightest deviation. Window and door openings can be highlighted in a different color. After every 4 rows, you need to do the jointing until the solution dries. This process is generally laborious, but the result is amazing.
