Tomaru Wall Coating (volcanic soil)

Transform your house into nature-friendly space with this liquid finishing material known as a substitute for water paint.
Advanced nanotechnology and eco-friendly materials made of clean soil (Interior/exterior finishing materials and interior design)
Tomaru Wall Coating purifies the contaminated indoor air. (Outstanding humidifying effects and dehumidifying effects)

Volcanic soil of Mount Haku

Mount Haku is known as one of Japan’s “Three Holy Mountains”. Water of Mount Haku flows into Tedorigawa with gravels and soil. Gravels and soil deposit at the mouth of Tedorigawa. These sediments are used as materials of Anti-Atopic Wallpaper after nano processing.


Breathing Soil Walls

Just like Korea, Japanese people have been constructing the walls with soil in order to overcome a humid climate. Japanese volcanic soil is a perfect material for humidity control because it has a small particle size and distinguished molecular structure differentiated from general clay or diatomaceous earth. Drawing on the wisdom of people of the past, we developed breathing Tomaru Wall Coating for modern interior design.

Secrets of Allophane

Allophane, the key component of volcanic soil, is generated during weathering of volcanic ash. Unlike general clay with crystalline structure and few pores, allophane with irregular particles is an amorphous with numerous fine pores. Allophane is the key material of Tomaru Wall Coating.

Tomaru Wall Coating made of clean soil

Tomaru Wall Coating is made of clean soil. Unlike general ceramic tiles made of volcanic soil and various additives for easy process and low production costs, Tomaru Wall Coating is made of clean soil and only 5% natural firming agent. As it is melted for application, it is easy to use for spray coating and plastering. Soil, the key material of the product, is adiabatic, nonflammable, and sound-absorbing and makes an atmosphere natural, gentle, and cosy.

Features of Tomaru Wall Coating (Volcanic Soil)

  1. Better humidifying effects and outstanding harmful substance removing functions than diatomaceous earth
  2. A nonflammable interior/exterior material which is a substitute for interior/exterior paints and wallpapers
  3. Its excellent humidifying effects remove frostiness on the ceilings, walls, and floors.
  4. Purifies the air by absorbing and decomposing harmful substances and bad smells
  5. An easily applicable natural finishing material that prevents sick building syndrome
  6. Used for rainwater purification, sewage treatment, wastewater treatment, etc.

100% eco-friendly functions of Wall Coating (volcanic soil)


100% eco-friendly functional finishing material!

  1. Prevents sick building syndrome and atopy (Absorbs and decomposes formaldehyde, toluene, and other harmful substances)
  2. Outstanding dehumidifying effects and moisture-proof effects (Prevents frostiness)
  3. Deodorization and air purification
  4. Antibacterial effects and antifungal effects
  5. Flame-resistant, flame-proof, etc.

The causative agents of sick building syndrome

  • The causes of sick building syndrome
  • Formaldehyde is known as one of the most common causative agents of sik building syndrome. A newly built house constructed with materials containing formaldehyde emits it to indoor space for several years.
  • Harmful organic chemicals emitted by construction materials are the causative agents of sick building syndrome

Absorption and decomposition of the causative agents of sick building syndrome

Absorbed formaldehyde combines with oxygen and turns into silicic acid. Again, silicic acid combines with oxygen and turns into water and carbon dioxide. Once silicic acid has a chemical reaction with alkali of Zero Stone (volcanic soil), it is neutralized to calcium silicate which is harmless to humans.

Structure of Tomaru Wall Coating

Volcanic soil is a porous mineral substance with numerous fine pores. Precise pores absorb and decompose harmful substances, moisture, and bad smells in the air.

The Effects of Wall Coating

Deodorization effects

Toilets, cigarettes, pets, and food waste generate bad smells. Zero Stone Walls deodorizes the air by absorbing ammonia and other substances. Zero Stone Walls has better deodorization effects than the walls made of diatomaceous earth.

Prevention of the proliferation of molds and mites

Molds and mites easily proliferate when humidity is 80% or higher. The outstanding humidifying effects of Zero Stone Walls prevents molds and mites from proliferating, staves off frostiness in winter, and maintains humidity at a proper level between 40% and 70%. Humidifying effects

Humidifying effects

Removal of dews and frostiness in the rainy season and winter
It absorbs moisture when humid and releases moisture when dry. Its outstanding humidifying effects maintain humidity at a proper level, stave off frostiness, and prevent molds and mites from proliferating.

Absorption and decomposition of harmful substances

Zero Stone creates a safe indoor environment and protects our children from harmful substances.
It absorbs and reduces harmful VOCs (Volatile Organic Compounds) emitted from buildings and furniture, such as formaldehyde and toluene.

Prevention of frostiness

Its excellent humidifying and dehumidifying effects prevent frostiness.

Dehumidifying when the relative humidity is high

Dehumidifying when the relative humidity is high

Humidifying when the relative humidity is low
