Kastus Ceramics is a spray designed to prevent the spread of harmful bacteria. The light-activated solution carries a range of additional benefits to ceramic surfaces, including scratch and stain resistance, non-toxic, no visible changes to the surface and it provides permanent surface protection.

Kastus Ceramics is effective in indoor or outdoor lighting conditions. To unlock the benefits of Kastus Ceramics, the spray is applied to the ceramic surface during the manufacturing process, prior to firing. With an ability to endure exceptionally high temperatures, a chemical reaction is triggered during the first firing process.

This value-adding technology can be applied to any ceramic surface and will transfer all the benefits of Kastus Ceramics to the finished product. This is done without impacting the appearance and texture of the surface, is environmentally-friendly and economically viable.
