THIS PRODUCT REQUIRES JESMONITE SUPER PLASTICISER.



Jesmonite AC830 is a rapid-setting acrylic-modified cementitious composite. The material is designed to be used for all cast stone and wet cast applications and is supplied with a separate plasticiser to aid flow, reduce shrinkage and cracking during curing, and enhance final strengths and thus ultimate durability.

Mix Ratios

For fine decorative castings, weigh the Liquids and Base into separate clean containers at the following ratios:

Jesmonite AC830 Liquids - 1 part by weight
Jesmonite AC830 Base - 7 parts by weight
Jesmonite Super Plasticiser - 8-12g/kg of mix
 

The working time (pot life) for AC830 is around 20-30 minutes (temperature-dependent) before it becomes unworkable and begins to set. Jesmonite AC830 achieves over 90% of its ultimate strength in the first 24 hours. Cast objects should be kept in a warm, dry environment during this period.
