Crafting concrete

Hobby concrete is a fine-grained concrete that's suitable for hobby use and can be used for casting and modelling. You can either cast with hobby concrete in moulds made of acrylic, plastic, silicone, papier-mâché or similar, or you can choose to model with the hobby concrete freehand using modelling tools. Choose between ready-mixed hobby cement/hobby concrete, or buy concrete powder that you can mix up yourself in water for softer models.
