Jesmonite AC730 is a rapid setting acrylic modified cementitious composite. The system is designed for glass reinforced decorative structures, and can also be used for small castings. It is shrinkage compensated material of low permeability and is durable in all conditions of external weathering including water features.
The compound has a reduced free-lime content, and is of low alkalinity, leading to major reductions in efflorescence in comparison with ordinary Portland cement systems. The material 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.
AC730 is available in six stone finishes; Natural, Bathstone, Yellow Sandstone, White Marble, Portland, and Silver Grey Granite.
