Achieve fireproof, quasi-fireproof, and quasi-fire-resistant with oyster shell power! Strong against water and five times stronger!
Jointly developed with Kinki University and obtained a patent! Seto plaster: shortened construction period, five times the strength, fire-resistant, quasi-fire-resistant, and quasi-fireproof certification obtained from the Minister. This is a revolutionary wall material made from plaster that achieves incredible high strength, high adhesion, and rapid hardening by mixing calcium ion water extracted from Hiroshima oysters. With five times the strength and a reduced likelihood of cracking, it is also effective for seismic reinforcement. Zero chemical materials such as resins! It is 100% natural material plaster. The alkaline effect is also expected to be effective for COVID-19 measures!

basic information
The wall material "Seto Shikkui," made from calcium ion water generated from oyster shells, is a revolutionary new material for walls. Seto Shikkui is a natural plaster that is gentle on both the body and the environment, developed through joint research between Kenchikusha Co., Ltd., Yuwan Village, and Kinki University. Through extensive research, it was found that the calcium ion water contained in Seto Shikkui reacts with carbon dioxide in the air, transforming into solid calcium carbonate. During this process, when the plaster dries and shrinks, it effectively fills the gaps that form inside, increasing its strength. The strength is five times greater, and it aims to create sand plaster walls with a thickness of 30mm or more (15mm thick wood lath and 15mm thick plaster). It is effective for breathability, heat retention, air purification, and condensation prevention. Furthermore, the unique effects of the plaster can be expected to last for many years in proportion to the amount used. We invite you to try this eco-friendly wall material, which offers reduced construction time and costs when used in conjunction with wood lath.
