Products for Construction and Civil EngineeringAron Wall
For general exterior wall improvement work on RC and ALC panels
Pioneering products that first introduced the idea of waterproofing to the construction of exterior wall coatings. Since we released the product in 1973, member construction companies nationwide have used it to cover 100 million square meters. It is a highly functional acrylic gum protective coating that is highly regarded by the architecture industry.
Extending the Longevity of Buildings while Preserving the Environment
Aron Wall protects buildings based on four fundamental concepts.
- Protect buildings
- Protect buildings from harsh natural elements for a long time
- Maintain the design aesthetic
- Maintain the exterior design aesthetic for the life of the building
- Be environment-friendly
- Offer environment-friendly installation solutions
- Deliver cost performance
- Reduce total costs through increased performance
Accommodating a wide range of construction needs, from new builds to remodels
Protect buildings from harsh natural elements for a long time
Preventing water leaks and rebar corrosion
Aron Wall capitalizes on the superior flexibility of acrylic rubber to stop rainwater penetration and makes the coating film harder to crack even when exterior concrete walls crack due to drying shrinkage. This also prevents rebar corrosion and alkali-aggregate reactions that cause expansion cracks in concrete.
Preventing concrete degradation
A one-millimeter thick coating of Aron Wall is equivalent to an approximately five-meter thick layer of concrete. Aron Wall’s superior air tightness shuts out carbon dioxide gas, preventing concrete neutralization. When used in improvement work, Aron Wall can also effectively restore alkaline conditions.
Preventing ALC degradation
Aron Wall forms a continuous, flexible and seamless coating that even covers masonry joints during RC and ALC exterior wall improvement work, which reduces base material treatment costs and effectively improves the durability of exterior wall ALC panels and sealants, which prevents degradation.
Preventing salt and freeze damage
Aron Wall’s ability to prevent the penetration of salt, oxygen and moisture also helps it prevent early degradation of RC structures caused by salt damage. In addition, Aron Wall offers excellent waterproofing performance and breathability that discharges moisture from inside concrete, which maintains dryness and helps stop freeze damage.
Preventing detachment of finishing mortar on exterior walls
Aron Wall prevents the detachment of finishing mortar on exterior walls thanks to its prolonged flexibility and ability to maintain membrane integrity, thus minimizing damages from earthquakes or other natural disasters.
Damage reduction capabilities validated following the Great Hanshin-Awaji Earthquake
Aron Wall can minimize damages to finishing materials even near the base during major earthquakes thanks to its long-term flexibility and ability to maintain membrane integrity.
Maintaining the Aesthetic Design
Maintaining the exterior aesthetic design for the life of the building.
Repairing Simple Unnoticeable Cracks
Using a coat of Aron Wall on top of a coat of Aron Wall SH, a base shock-absorbing material, applied to cracks will prevent cracking from recurring for a long time and reduce the visibility of cracks.
Conventional u-cuts and sealant filling work cause noise and dust, and leave a visible area where the crack was repaired, which becomes even more visible as time passes.
Low Contamination Design Specifications
Aron Wall’s finish coat contains a hydrophilicity technology that uses special high-durability hydroceramic ingredients that enable dirt and grime that accumulate on the coated film to be washed away by rain.
Aron Wall offers excellent flexibility and low contamination design specifications that make it harder for dirt and grime to accumulate, thus successfully maintaining a building’s exterior aesthetic design for a long time.

Environment-friendly Installation Solutions
Complete water-soluble specifications
Toagosei proposes complete water soluble specifications as part of its efforts to comply with VOC regulations and be more environment-friendly.
A complete water-soluble specification means that a product is comprised entirely of water soluble catalyst materials and not organic solvents for the primer, waterproofing and finishing top coat layers. These are truly environment-friendly designs that are considerate not only of workers and residents, but also the surrounding community.
- The primer amount and drying time will vary depending on the type and conditions of the base material and work environment.
Helping reduce waste by extending longevity
Our mission is to reduce the resources we use and curb the amount of waste we produce, which will safeguard the global environment and conserve limited resources for future generations. As a product that protects buildings for a long time, Aron Wall is helping to safeguard the environment by reducing waste.
- Reduce: Curbing the use of materials that generate waste
Delivering Cost Performance
Reducing total costs through increased performance
Reducing base material treatment costs for exterior wall improvements
Aron Wall forms a continuous, flexible and seamless membrane that even covers masonry joints during RC and ALC exterior wall improvement work, which reduces base material treatment costs and effectively prevents the possible detachment of exterior ALC panels or sealants due to degradation.
Reducing crack repair costs
Applying a coat of Aron Wall SH, a base shock-absorbing material, to cracks when applying Aron Wall can reduce the number of work days and level of expertise required compared to conventional methods*, which in turn can reduce the cost of base material treatment work.
- U-cut + sealant filling ≠ polymer cement mortar filling
