Jesmonite AC84 Base

Jesmonite AC84 is a flexible, lightweight casting material perfect for creative applications in art, craft, and design. Ideal for building layered surfaces, coating foam, or creating durable sculptural pieces, AC84 sets quickly and is easy to work with. Its smooth finish and flexibility make it especially suited to thin, detailed forms and large-scale decorative work. Water-based and solvent-free, it’s a safer, eco-conscious choice for artists and makers exploring lightweight construction and surface design. Mix Ratio: 5:1 (Base to Liquid by weight)

It is a composite material made by combining a water-based acrylic resin, known as the Liquid, with a reactive mineral powder, known as the Base. When mixed, the two components create a smooth, pourable substance that sets into strong, detailed casts, perfect for moulding and surface finishes.

Jesmonite AC84 is great for flexibility, quick drying (2hours) and weather resistance.
