Basic Materials Needed: - Leaf - Flat work surface - Concrete Mix - Sand or Fine Gravel - Plastic Drop Cloth or Trash Bags - Rubber Gloves - Stiff Bristled Brush - Concrete Sealer - Disposable Foam Brush - Dust Mask - Shallow container for mixing concrete - Water - Shallow Box to contain sand (Optional) - Concrete Dye (Optional) - Acrylic Paint (Optional)
Alternate mix: 3 Parts Sand, 1 Part Portland Cement, and an equal mixture of water and fortifier (bonding agent).
Add water until the mixture feels like thick brownie batter. Mix well. Let mixture stand 5-10 minutes before applying to the leaf.
Choose a work area where the casting can sit and cure undisturbed for a week. Garages or covered patio areas work well. This can be a messy job, so wear old clothes or an apron to protect your clothing and always were rubber gloves when working with concrete because the Portland cement in the concrete is caustic and can burn your skin. If you plan on doing this project outside, choose a shady location and a time when it won't rain for at least two days. If the outside location is covered and partially protected from the elements, that is good too and rain is not much of a factor.
