Flexiguard Sealer is based on nano-technology and is a stain-resistant, invisible sealer which creates a clear, UV-stable, and extremely durable surface for all Jesmonite composites when used externally. Flexiguard is unique in that it creates a low-energy surface that prevents soiling, and mould and fungal growth. This product, once applied, significantly reduces the need for cleaning and maintenance and is effectively permanent due to the chemical bond made with the Jesmonite substrate (subject to abrasion). It can be applied very easily almost anywhere – on site or in a manufacturing environment.
