Mix the material with water and is ready for use. Relation: 125-190ml water for 1kg of powder.
Prepare the mold (preferably plastic, strong cardboard or paperboard, paper or wood). Before molding, the mold must be coated with edible oil or separator, which will make it easier to remove concrete from the mold. Mix the powder in the correct ratio with water until you reach the desired density. Pour the mixture into the mold. If you use more water, you can extend the clamping time. After approx. For 2 hours, the product can be removed from the mold (the time depends on the thickness of the product). The edges can be sanded with abrasive paper and allow the product to dry. Of course, concrete can also be painted (acrylic paint, metallic paint, crayons …) or leave the natural color of concrete.
