The Gypsona fast-setting plaster bandage requires soaking and remaining in water before use. It hardens in approximately 5 minutes, allowing for quick attainment of the necessary stability. The bandage is designed to require firm compression in order to remove excess water and for the finished plaster cast to gain the required strength as quickly as possible. After just 30 minutes, it is possible to apply short-term pressure. They are also ideal for constructions such as models. Available in a pack of 2 pieces.
