Casting concrete, durable, fluid, extra strong casting concrete for use both indoors and outdoors. The concrete is suitable for casting in moulds and other creative techniques. If you pour the concrete into latex or plastic moulds, we recommend greasing the object with cooking oil. If you want to cast in cardboard/card moulds, then brush with natural latex first. The concrete also works for items such as bottles or old boots – but then you should expect to break the mould in order to remove your creation.
