Jesmonite AC730 is a rapid setting acrylic modified cementitious composite. The system is primarily designed for glass reinforced, lightweight, hand laminated decorative applications, but it can also be used for small decorative castings.


  • Shrinkage compensated for material of low permeability
  • Durable in all conditions of external weathering including water features.
  • Reduced free-lime content, with low alkalinity,
    leading to major reductions in efflorescence in comparison with ordinary Portland cement systems.
  • Contains a fine decorative aggregate and powder pigments, carefully controlled to give a consistent decorative surface finish after treatment with a proprietary brick cleaner or acid etch.

Design Flexibility

AC730 is the most popular micro-cement product within our range of materials, typically used in external environments, but equally suitable for internal features, AC730 offers a distinct high-detailed surface finish without compromising on performance.

Examples of applications where AC730 can be used are:

  • Cladding Panels
  • External Architectural Features
  • Homewares
  • Stone-Effect Castings
  • Ornate Mouldings
  • Furniture
  • Decorative Murals/Artworks
  • Sculptural Pieces

AC730 can be sealed using Jesmonite Flexiguard or Penetrating Sealer (dependent on application) to create a water and stain-resistant piece, for scaled applications AC730 can be combined with AC730 Spray Liquid to allow the product to be utilised with a spray gun, therefore speeding up the prospective application.

Our bespoke colour-matching service is available for this product, which utilises our industry-leading colour-matching team who can analyse the pigmentation of many objects/surfaces and provide a custom blended AC730 base for your use. MOQ 500kg.
