AC730 Liquids, Powders & Kits

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.

Products benefits:

  • Superior cast and glass reinforced mouldings
  • Solvent free & no VOC’s
  • Fire resistant
  • Lightweight
  • Impact resistant


  • Shrinkage compensated 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 ELEVEN stone finishes:

Natural, Bath Stone, Yellow Sandstone, White Marble, Portland, Silver Grey Granite.

***NEW for 2021: Charcoal Black, Cotswold Honey, Marigold, Old Terracotta and Brick Red. ***

Jesmonite® AC730 is a rapid setting acrylic polymer modified cement based composite.

It is a shrinkage-compensated material of low permeability and is durable in all conditions of external weathering.

The compound is alkali free and as such is free from the efflorescence associated with ordinary Portland cement based systems.

The product 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.

It is supplied as two components, a water-based acrylic liquid, and a blended Base.

Glass reinforced decorative architectural mouldings, and small castings. Glass reinforcements such as Jesmonite Quadaxial Fabric or 13mm Glass Chopped Strands can be utilised for lightweight, high impact panels.  It can also be used to create garden ornaments and statuary, and is suitable for water-features.


Improved flexural strength and stability

Excellent abrasion resistance and impact strength

High compressive and tensile strength

Rapid curing and high early strength gain

Shrinkage compensated and dimensionally stable


Liquids are supplied in 1kg, 5kg, 25kg canisters and 1,000kg Bulk IBC’s, Base is supplied in 5kg and

25kg buckets and 1,000kg FIBC’s. ( P.O.A )


As a basic rule liquid containers should be kept well sealed to prevent water evaporation and skin

forming. They should be stored at a constant temperature between 5 – 25oC and used within six

months. Freezing must be avoided. Base should be kept dry and stored at 5 – 25oC.
