AC730
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.

Information
- 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.
- Available in a ‘Gel Coat’ format offering increased viscosity.

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.
