What is Japanese-born plaster “shikkui”?

Shikkui is a Japanese plaster. It is traditional Japanese wall material whose main component is slaked lime.

Wall materials containing slaked lime as the main component are often found in the world. Stucco is one of them, and it has evolved uniquely according to the Japanese environment.

Shikkui is a natural material. The traditional method of plaster is made by mixing salt-grilled slaked lime, seaweed glue, and hemp fiber.

The white and evenly finished plaster is very beautiful.

Himeji Castle, a World Heritage Site, has a pure white appearance. The exterior walls are finished with plaster, and its beautiful appearance attracts many people.

 

How is it different from European plaster?

Stucco has been used for a long time in Europe as well. There are differences in characteristics from Japanese plaster.

The walls of Western architecture are made of stone and brick, and the plaster has been thickly painted so as not to break the walls. A lot of sand and fibers are mixed to make the wall thicker. Therefore, the finish is rough and gives a somewhat rugged impression.

On the other hand, Japanese houses are wooden houses. The house is supported by columns and beams, and the walls do not need to be strong. Therefore, the plaster does not need to be applied thickly, and the aggregate is minimal. Therefore, its surface is smooth and the “white” of slaked lime stands out.

 

What is the function of shikkui?

Slaked lime, the main component of plaster, has various functions.

Slaked lime (calcium hydroxide), which is the main component of plaster, has strong alkaline and porous properties, and has various functions.

Stucco is also very effective for modern homes.

Deodorant

Adsorbs ammonia, hydrogen sulfide, and methylcaptan, which are the main causative substances of unpleasant odors.

It is effective against living odors such as bacteria, germs, mold, tobacco and pet odors.

Antiviral / antibacterial

Strongly alkaline calcium hydroxide

It blocks the growth and growth of bacteria and also suppresses viruses.

 

VOC adsorption

Adsorbs VOCs such as formaldehyde, which is the causative agent of sick building syndrome.

For rooms with weakly resistant children, the elderly, and pets.

 

CO2 absorption

Reduces the concentration of carbon dioxide in the room and reduces the effect on the body.

It keeps the air in the room fresh.

 

We have developed a wallpaper “shikkui fleece” that has the function of shikkui.

 

shikkui is a great wall material, but it has problems such as difficulty in construction, high material cost, and maintainability.

Advanced plastering techniques are required to evenly paint the plaster. Even in Japan, the number of highly skilled craftsmen is declining, and construction costs are increasing year by year. In addition, plaster has the disadvantage of being easily cracked, so maintenance is essential.

Our plaster fleece is a high-strength fleece coated with plaster paint. Since it can be constructed in the same procedure as the wallpaper, it does not need to be constructed by a plasterer. In addition, there is no need to worry about cracking because the high-strength wallpaper is coated with plaster paint that is hard to break.

In addition, the beautiful white finish is comparable to real plaster.

Why don’t you incorporate beautiful plaster into your wallpaper?
