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, highimpact 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.
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.
