shikkui fleece

Creating a safe and comfortable space with the power of plaster

shikkui fleece is made of fleece wallpaper coated with plaster paint.
The main ingredient of plaster, slaked lime, has various functions including deodorizing and antibacterial properties,
while the base material, fleece wallpaper, has excellent moisture control and durability, and is easy to install.
A plaster fleece combines the benefits of plaster and cloth.

The function of slaked lime

Slaked lime, the main ingredient of plaster, has the functions of deodorant, anti-virus, antibacterial, VOC absorption and CO2 absorption.

  • Deodorizing

  • Antibacterial and antiviral

  • VOC adsorption

  • CO2 absorption


Adsorbs ammonia, hydrogen sulfide and methylcaptan, the main causes of unpleasant odors. It is also a countermeasure against bacteria, germs, mold, and household odors such as the smell of cigarettes and pets.

Antibacterial and antiviral properties

Strong alkaline calcium hydroxide inhibits the growth and proliferation of bacteria and viruses.

[Antibacterial effect]

An antibacterial activity value of 2.0 or higher, as determined by the test method specified in JIS Z 2801, is considered to be effective.

[Measuring method] JIS Z 2801 compliant. – Bacteria (100,000 to 400,000 bacteria) are placed in contact with antimicrobial treated objects, and the increase or decrease in the number of contacted bacteria is measured to confirm the antimicrobial effect compared to non-treated products. In-house research.
[Antiviral effect]

VOC adsorption

Adsorbs VOCs such as formaldehyde, a causative agent of sick house syndrome.
It can be effective in spaces with children, elderly people and pets with low resistance.

CO2 absorption

It is expected to lower the carbon dioxide concentration in the room and reduce its effect on the body.

High functionality

Prevents condensation and mildew

“shikkui fleece” boasts high moisture absorption and desorption thus reducing condensation and mold formation. It can reduce the deterioration of buildings due to condensation and health hazards caused by mold. Geographical locations such as Okinawa (Japan) and Thailand, well known for their high temperatures and humidity, have seen successful applications of our products.

High moisture absorption and desorption inhibits mold and condensation absorption and desorption properties were compared. shikkui fleece were 105g / ㎡, while normal vinyl cloth absorbed 43g / ㎡. The amount of moisture released was 16 g / ㎡ with vinyl cloth, while it was 77 g / ㎡ for shikkui fleece.

“eterno” has high moisture absorption properties and is less prone to condensation than vinyl cloth.

  • When the temperature inside the equipment was 40.2°C, the humidity was 56%. There was no condensation inside the equipment.
  • When the temperature inside the equipment was 37.8°C, the humidity was 90%. Condensation was found inside the equipment.
[Methods] The experimental apparatus was set up in a room temperature of 25°C. A container of water was placed in the apparatus. A container filled with water was placed in the device and warmed by a 40W light bulb, and humidity and condensation conditions were measured after six hours. In-house investigation

High durability

“shikkui fleece” is a wallpaper with high strength, moisture resistance and long-lasting use. It can be repainted more than 10 times with water-based paints.


“eterno” has high tensile strength. This makes it resistant to tearing when the wall surface is displaced or moved by cracks or distortions in the building.
The tensile strength of shikkui fleece was compared with vinyl cloth.
The tensile strength of vinyl cloth was 46 N / 15 mm in the vertical direction and 31.4 N / 15 mm in the horizontal direction, while the tensile strength of shikkui fleece was 133 N / 15 mm in the vertical direction and 76.4 N / 15 mm in the horizontal direction. It was.

[Methods] Complies with JIS P 8113. The tensile strength of paper and paperboard is measured using a constant-speed extension tester. In-house research

In the case of vinyl cloth

This is a paper-lined wallpaper with a sheet of polyvinyl chloride resin (PVC).
Because the backing is paper, it has low strength and is not able to respond to the movement of the building structure, and is prone to cracks and tears.

For concrete and paint finish

Concrete develops cracks (cracks) due to building movement and distortion. When painting directly onto concrete, if cracks appear in the substrate, the finish will crack as well.

The high strength fleece “eterno” does not follow the cracks and keeps a good appearance.

Resistant to moisture

“shikkui fleece” has low elongation in water and is less prone to stretching and shrinking due to moisture. Therefore, unlike vinyl cloth, it is less likely to expand or contract due to moisture and less likely to move or peel off from the wall caused by expansion or contraction.

Resistance to deterioration

Plasticizers are added to vinyl cloth to make PVC resin (PVC) more flexible, but UV light exposure releases the plasticizer.
In the process, the flexibility is lost from the PVC.
As a result, the vinyl cloth will harden in 5-6 years and the joints in the cloth will open up.
In addition, degradation and yellowing of PVC without plasticizer will occur. In this respect, the fleece wallpaper without plasticizer is unlikely to deteriorate.

Discarded vinyl cloth

Environmentally friendly and highly safe

eterno is a wallpaper made of natural materials.
It is an Eco-friendly and highly safe wallpaper.
You can use it with confidence from children to the elderly.

Environmentally friendly

FSC® certified wallpaper

“shikkui fleece” is part of the “eterno” series, FSC Certified, which is rare in Japan.

※ FSC ・・・ FSC certification ensures that products come from responsibly managed forests that provide environmental, social and economic benefits.

Waste Reduction

“shikkui fleece” can be painted over with a water-based paint. This reduces waste as there is no need to remove the existing wallpaper when renovating.



“eterno”, unlike vinyl cloth, does not use plasticizers. Plasticizers contain endocrine disruptors, which can cause sick building syndrome.
Plasticizer-free fleece wallpaper does not emit VOCs and poses no threat to sick building syndrome.

In Japan, F☆☆☆☆, the highest of the four grades of formaldehyde emissions set by JIS (Japanese Industrial Standard) and JAS (Japanese Agricultural Standard) , has been certified.

Installation and maintenance


“eterno” is a product that combines the beauty of the finish with ease of installation. For example, it can be applied to a 50-square-meter concrete substrate in about the same amount of time as a paint finish. – The finish is both more beautiful and more durable than paint.
– The finish is more aesthetically pleasing and more durable than paint.

Estimated working hours for finishing on a concrete substrate of 50 square meters

Light stains on fleece wallpaper can be scrubbed off with a sponge. Fleece wallpaper can also be repainted over the finish. Stains that cannot be removed can be repainted with repair paint.
Small dents can also be removed by moistening the pulp and drying it with a hairdryer. This will expand the pulp and make it less noticeable. Partial patchwork repair is also possible.
