1. What is "painted walls" with a craftsman's sense of style?
"Nurikabe(塗り壁)" is a method of wall construction in which several layers of wall material made of natural materials are applied on top of a base coat. The surface layer is called the "top coat," and the wall is finished by coating the top coat with a wall material made of clay, plaster, diatomaceous earth, or other natural material.
Throughout Japanese history, painted walls have been used on the exterior walls of private homes, storehouses, castles, and other structures. The durability and safety proven by their long history, as well as the craftsmanship of the design, have attracted attention, and in recent years, more and more people are interested in incorporating lacquered walls into the exterior walls of their homes.
All painted walls are done by hands of craftsmen. Using natural materials such as soil and sand to reflect the individuality and experience of the craftsman, it is truly a traditional Japanese method of construction.
It is also widely used not only for Japanese-style houses but also for Western-style houses, as its texture can be freely changed depending on the finishing method.
2. 3 advantages of painted walls
Here are three advantages of selecting painted walls for exterior walls. Some of the advantages are not found in other wall materials, so please check them out.
2-1. It will be a one-of-a-kind stylish exterior wall
All of the work is done by hand by craftsmen, making each wall a one-of-a-kind exterior wall. The finish varies greatly depending on the type of brush and the workmanship of the craftsman, so if you communicate your ideal finish, you can create a unique and fashionable exterior wall.
If you want to create a unique exterior wall, we also recommend that you consult with us to see if we can incorporate an original design.
A flexible contractor will be able to fulfill your wishes, such as putting your family's handprints on the painted wall, or embedding glass or marbles to make it more colorful. The originality that can only be achieved through the handiwork of craftsmen is one of the great attractions of painted walls.
2-2. Enjoy a natural finish
Another appeal of painted walls is that they offer a natural finish. Since many natural materials such as soil and plaster are used, you can feel the natural texture that oozes from the materials.
Furthermore, while wall materials that are "put up and finished" such as siding and tiles are uniform in design, painted walls are not necessarily uniform because they are handcrafted. Depending on which wall material is chosen for the finish and how it is applied, the feel and atmosphere will be completely different, allowing you to enjoy the unpretentious, natural warmth that only handcrafted work can provide.
2-3. Excellent fire resistance
Another advantage of painted walls, which are mainly composed of natural materials, is that they are highly fire-resistant. Mortar and plaster used for painted walls are considered "noncombustible materials" under the Building Standard Law, and are highly evaluated for their fire resistance.
This characteristic has been used since ancient times. Japanese traditional houses are often made of flammable paper materials such as shoji and fusuma sliding doors, but by partitioning the interior and exterior walls with non-flammable painted walls, flames were prevented from spreading in the event of a fire.
3. 4 disadvantages of painted walls
Although attractive, painted walls are not all advantages. Everything has its advantages and disadvantages, so make sure you know the disadvantages as well. Understanding the disadvantages will help you create the ideal exterior wall.
3-1. High cost and long construction period
As we have already mentioned, the disadvantage of painted walls is that the cost is higher because all the work is done by hands. In addition, there is no fixed price, as the cost is determined by a variety of factors, such as the wall material chosen, the extent of the work, and the degree of difficulty of the pretreatment.
Nevertheless, it is not surprising that the price is higher, since craftsmen spend a lot of time and effort on the work, using detailed techniques.
It also takes a longer construction period than siding and other methods. A wall is not finished when it is painted; it is not finished until it is firmly cured. It is necessary to allow for a reasonable construction period.
3-2. Prone to cracking
Another disadvantage of painted walls is that they are prone to cracking over time due to moisture loss and volume reduction. Cracks in painted walls can occur no matter how careful you are, so you may feel more comfortable if you recognize in advance that regular maintenance is necessary.
However, while painted walls are prone to cracking, they are also easy to repair. Light surface cracks can be maintained by yourself.
3-3. Stains are easily visible
Another drawback of painted walls is that they tend to show dirt. Normally, any exterior wall will become dirty due to irritation from rain, wind, and ultraviolet rays. However, in the case of painted walls, the nature of the finishing process makes the surface uneven, making stains stand out even more.
Therefore, to keep it clean, it will require regular maintenance, just like cracks.
Some types of painted walls are less likely to show stains. Plaster, for example, has the advantage of being relatively stain-resistant due to its self-cleaning effect caused by its strong alkalinity and high waterproofing properties. When choosing painted walls, a careful comparison of the characteristics of each wall material may help reduce the disadvantages.
3-4. The finish depends on the skill of the craftsmen
Because painted walls are done by hand, the finished product is in the hands of the craftsman. Some people may feel uneasy because the overall appearance as well as the detailed sense of design is left up to the craftsman.
In order to achieve the ideal exterior wall, it is necessary to make efforts such as checking past cases of the design company you request and communicating your wishes without compromise during the meeting.
5 major types of painted wall materials
Here we introduce 5 types of wall materials that are often used in actual construction. Since different materials have different characteristics, it is important to check the finish and functionality of each material to ensure that you will not regret your choice.
4-1. Slippery "plaster" with fine particles
Plaster, a typical type of painted wall, uses slaked lime (calcium hydroxide) as a raw material. It is a naturally occurring ingredient originally derived from coral reefs.
The main characteristics of plaster are its antibacterial and anti-fungal properties. This is due to the strong alkaline nature of slaked lime. It also has excellent durability and fire resistance, which is why it is used for buildings such as castle walls, shrines, and temples.
It is smooth to the touch with fine particles and is resistant to dust and dirt, so it is recommended for people who do not like a rough texture or who want to create a Western-style home.
4-2. "Diatomaceous earth" with coarse and rough particles
Diatomaceous earth, which we hear a lot about in recent years, is also often used for painted walls. Diatomaceous earth is a type of soil formed when the carcasses of diatoms, a type of algae, accumulate on the ocean floor. Diatomaceous earth has a rough, coarse texture and is often used for the exterior walls of Japanese-style houses.
It also has the added benefit of preventing condensation and other problems due to its excellent humidity control properties. Plaster, which is often compared to diatomaceous earth, also has excellent humidity control properties, but diatomaceous earth is more effective. If you live in an area with high humidity, please consider using diatomaceous earth.
4-3. "Mortar" with low price
Mortar is recommended for those who want to keep prices low. Mortar is a coated wall material made by mixing cement with sand and water.
Although it is susceptible to cracking and requires regular maintenance, it is the least expensive of the five types introduced here, making it easy to use. Another advantage is its superior design.
However, mortar can be finished in a variety of ways, and the skill of the craftsman is clearly evident. Therefore, it is important to find a skilled craftsman who can fulfill your ideal.
4-4. Traditional and modern "mud walls"
"Tsuchikabe(土壁)", the most widely used wall material in Japan's history, is a wall material suited to Japan's humid climate. As the name suggests, it is a natural material made of hardened soil, and excels in functional aspects such as heat insulation, fire prevention, humidity control, and soundproofing.
As time went by, the development of economical and cost-effective wall materials led to a decline in the use of earthen walls, but recently, the "environmentally and people-friendly material" and "high functionality" are once again attracting attention.
There is a wide range of clay wall textures, from rough and earthy to polished and smooth surfaces. Another point that allows for originality is that the texture and color can be adjusted depending on the ingredients and mixing conditions of the soil used in the mixture.
4-5. "Jolypate" has the top share of the domestic market
Jolypate is a type of mortar coating sold by AICA Kogyo, a company that handles housing-related products. The viscous wall material is resistant to cracking and has excellent fire resistance.
Jolypate's greatest appeal is its unparalleled variety of designs. With more than 180 colors and 100 designs, you can find the ideal exterior wall to match the atmosphere of your home. Jolipat is recommended for those who wish to have a unique exterior wall that cannot be found in any other house.
What materials other than painted walls are used for the exterior of houses?
Here is a brief introduction to materials other than painted walls. Please take a look at the features of each and compare them.
5-1. Reasonable "siding"
Siding is an exterior wall material in the form of panels. Because the panels are inserted into place, installation is simple and does not require the advanced skills of craftsmen as is the case with painted walls. In this respect, labor and construction costs can be reduced, and the construction period is also short. It is said to be the most widespread wall material in Japan today.
5-2. "Tile" with excellent durability
Tiles are made by baking natural materials such as stone and clay at 1,300 degrees celsius. Therefore, tiles can withstand heat up to at least 1,300 degrees Celsius, and can be said to have excellent fire and heat resistance. Another important feature is that they are made of an extremely hard material, making them durable and maintenance-free over the long term.
6. What to do when painted walls get dirty? What about maintenance?
Although painted walls have the disadvantage of being easily visible, it is a good idea to learn how to maintain them when you find stains. Here are some tips on how to maintain painted walls.
If it has not been too long since the stain appeared, you can maintain it yourself. Try the following order.
- Wash with water using a hose
- Scrub with a soft brush
- If water does not remove the dirt, apply a cleaning agent (e.g., Purelox-S)
The rule of thumb for maintenance of painted walls is to start with the least irritating and gentlest methods. If washing with water does not remove the paint, scrub with a brush, and if that does not remove the paint, use a cleaning agent.
For persistent stains due to age or stains in areas that cannot be repaired by yourself, it is recommended that you hire a contractor to maintain the wall. Although it is expensive, it saves time and effort, and the contractor will clean the wall appropriately according to the wall material to ensure a satisfactory finish.
7. The cost price of painted walls
The market price for the cost of painted walls is said to be "about 1 to 1.5 million yen" for a house of about 30 tsubo (about 1.5 square meters).
However, as mentioned earlier, the cost of painted walls is not a fixed price, but is determined by a variety of factors and cannot be generalized. Prices vary greatly depending on what type of finish is ideal, which material is chosen, and so on.
Therefore, it is important to ensure that the client's budget and ideals are communicated during the meeting with the contractor if he/she is going to commission a painted wall. Since all painted walls are made by hand, the contractor will be able to make a proposal that meets the client's needs.
8. Painted walls on the interior would give it a modern look!
When many people hear the term painted wall, they may think of exterior walls. However, many benefits can be received even when painted walls are used for interior decoration.
First, the "humidity control" characteristic of painted walls is ideal for keeping room temperature cool in summer and warm in winter. Furthermore, the use of fire-retardant painted walls for indoor use will provide peace of mind in the event of a fire, as flames are less likely to spread. The superior functionality of painted walls can provide a safe and comfortable indoor environment.
Another appealing point is that it brings the unique texture of painted walls into the interior. It will be a wonderful space where you can enjoy the modern atmosphere of natural materials on a daily basis.
9. Painted walls can be created by DIY, but please be aware of these attentions
Painted walls can also be DIY. Recently, there are sets available that can be easily DIY'd by a single woman.
However, there is a caveat to DIY painted walls. Although painted wall materials are natural, they are not 100% safe. Some ingredients may be dangerous if they accidentally get into the eyes or come into contact with the hands, so care must be taken when handling them.
In many cases, amateurs cannot achieve a satisfactory DIY finish when they attempt to paint walls that were originally done by craftsmen with decades of training. In particular, the work on exterior walls is extensive and difficult, so if you want a beautiful finish, it would be safer to leave it to a professional.
