Jesmonite limited was invented in 1984. The original compound was acrylic-modified gypsum composite with is still sold to this day. It was conceived as a safe alternative to fire glass (GRP) and as a lightweight alternative to traditional building materials.

Our continued commitment to invention and problem solving over the past 30 years has resulted in a range of material solution covering a myriad of internal and external applications for use across many industries including construction, marine and film.




Jesmonite is the ultimate chameleon material of the building industry – it can be used to replicate the appearance and texture of any surface finish in any number of colours.

The combination of natural raw materials with a special blend of water based pure acrylic polymers create a unique family of materials that have a number of product benefits that make Jesmonite superior to other building materials.

  • AS1530.1 Certified
  • Strong, flexible and more durable, making it high impact resistant.
  • Lighter than stone, glass-reinforced concrete, sand and cement products – perfect for film sets
  • Fire-resistant with a class zero fire rating, reduced smoke density and toxicity characteristics. Solvent free with no VOC’s
  • Replicates the very finest detail
  • Water-based not solvent-based, making it kinder to the environment
  • Can be pigmented to any colour or RAL reference. It can also mimic any texture and reproduce the effect of materials such as stone, metal, wood, leather and fabric
  • Perfect for building, sculpting, pottery, film sets and more
