Exterior walls

ARONWALL

Product Name: ARONWALL

For general exterior wall improvement work on RC and ALC panels ARONWALL is a pioneering product that first introduced the concept of waterproofing and building protection to the exterior wall painting industry. Since its release in 1973, ARONWALL has been used by our construction partners to cover more than 100 million m2 of exterior walls nationwide in Japan. As a result, this ultra highly functional acrylic rubber protective coating has earned a strong reputation in the construction industry.

CLEARWALL

Product Name: CLEARWALL

For improving tiled exterior walls of commercial facilities and residential buildings This transparent and flexible coating film prevents rain from seeping into cracked tiles and joint mortars, preventing tiles from detaching in the future and improving building safety.

ARON QD TILE

Product Name: ARON QD TILE

For improvement work of finishing coatings for construction and exterior walls of RC structures ARON QD TILE is an elastic tile that reduces costs while also offering strong adhesion and coverage of cracks. This primer-less high-performance elastic tile combines the benefits of both acrylic rubber systems and polymer cement systems.

Roofing materials

ARONCOAT SQ

Product Name: ARONCOAT SQ

A unique waterproofing for flat and pitched roofs that can also be used as an overlay for asphalt roofs and waterproofing exposed asphalt ARONCOAT SQ is a roof waterproofing coated film that uses an acrylic rubber system with two reactive ingredients. In addition to the features of conventional coated film waterproofing, it is exceptionally durable, eco-friendly and reliable. The high performance is officially recognized by obtaining "Construction Technology Examination and Certification Project" by a third-party organization.

ARON QD BOSEI COAT

Product Name: ARON QD BOSEI COAT

For improvement work on folded-plate roofs of factories and warehouses and on ribbed seam roofing of gymnasiums ARON QD BOSEI COAT is made from highly elastic acrylic rubber providing exceptional waterproofing, corrosion resistance and heat shielding.

ARON QD SLATE

Product Name: ARON QD SLATE

For improvement work on folded-plate roofs of factories and warehouses and on ribbed seam roofing of gymnasiums ARON QD SLATE is designed to protect, reinforce and block heat using its highly elastic thick acrylic rubber. ARON QD SLATE can encapsulate asbestos from old buildings and prevent it from becoming airborne for a long period of time. It can also breathe new life into colorful and attractive roofs.

Material for preventing water absorption by exposed concrete

AQUAPROOF

Product Name: AQUAPROOF

For improvement work on tiled exterior walls and exposed concrete AQUAPROOF prevents rainwater from being absorbed by buildings and reduces the breakdown of porous inorganic materials.
