When it comes to decorating your yard, concrete accessories often create a welcome accent. From spheres to statues to birdbaths, there are a wide variety of concrete accessories to choose from. But sometimes, it can be difficult finding the right accessory for your yard. You could commission an artist to create your design. Or you could cast it yourself using a latex mould, which you'll learn how to do here. Making your own latex mould requires some skill, but is less costly than purchasing one outright.

Things you need
- Air-dry sculpting clay
- #80 natural latex
- 5 pieces of acrylic sheeting, slightly larger in size than your concrete model
- 16 1" screws
- Hot glue
- Glue gun
- Mold sealant (Smooth-On superseal)
- Release agent (Smooth-On universal mould release)
Sculpt a scale model of your concrete creation using air-dry clay. Set aside to dry.
Secure model to one sheet of acrylic by placing a bead of hot glue in the middle of the sheet, and pressing the mould securely in place. This will be the baseboard.
Coat the model with sealant and let dry.
Construct the mould box around the model by attaching the remaining 4 four acrylic sheets to one another and the baseboard with screws.
Seal the cracks in the mould box by caulking with hot glue.
Coat the model and the sides of the mould box with the mould release.
Pour latex into mould box and let vulcanise (solidify). #80 latex generally takes 3 days to vulcanise.
After latex has solidified, deconstruct the mould box by removing the screws and pulling apart the acrylic sheets.
Cut latex mould in half and peel away from the model. Your latex mould should now be ready to cast.
