Cera-Mix Standard Casting Plaster is an easy-to-use casting plaster that captures fine detail beautifully, making it a wonderful material for creating keepsakes, nature casts and d ecorative crafts at home. Simply mix with water, pour into a mould and leave to set — once fully hardened, it can be painted, decorated or carved to create something truly personal. We particularly love using it to make botanical castings with children. Press leaves, flowers or shells into modelling clay or plasticine to create a simple mould, pour in the plaster, and once dry you'll have a beautiful nature impression ready to display or paint — though all mixing and handling of the plaster should always be carried out by an adult. Why We Love It The level of detail this plaster captures is quietly impressive — delicate leaf veins, the ridges of a shell and the tiny lines of a child's fingerprint all come through with real clarity. Once hardened, the porous surface can be carved and shaped with suitable tools as well as painted, so the creative possibilities don't stop when the plaster sets. From botanical wall plaques and seasonal decorations to handprint keepsakes and small sculptures, this is a material that genuinely grows with your creative ambitions. Product Details Materials: Standard casting plaster Mixing ratio: 1kg plaster to approximately 500ml water Working time: Approximately 18 minutes Initial drying time: Approximately 30 minutes Fully hardened after: Approximately 5 days Age: + 8 years with adult supervision Safety Information: For adult use only. Adult supervision is required at all times. Not suitable for children to mix or handle in powder form. Avoid breathing in plaster dust — mix in a well-ventilated area and consider wearing a dust mask. Avoid contact with eyes; if contact occurs, rinse thoroughly with clean water. Never pour leftover plaster down the sink, as it can harden and block drains — allow excess plaster to set before disposing of it with household waste. Plaster generates heat as it sets; never pour plaster directly onto skin or place hands or fingers into setting plaster, as this may cause burns. Show more
