Rather than recycle your used plastic containers, why not use them to make small planters?

With ShapeCrete it's quick and easy to make your own unique planters.

STEP 1: Supplies

STEP 2: Mix

Mix ShapeCrete to a Clay-Like Consistency. You can add pigment if you want to make it colored.

STEP 3: Pack

Pack the mix in the bottom of the container first, then work it up the sides. Smooth the top flat with a trowel to give the top edge an even surface. Cover with plastic and cure for 24 hours.

STEP 4: Demold

Before cutting open the form, sand the top edge with a diamond hand pad or sandpaper. This will help prevent chipping on the top edge.

Slit the plastic with a razor blade, utility knife, or scissors. Then gently peel the plastic away.

STEP 5: Drill a Hole (Optional)

It's easy to drill holes in ShapeCrete with a masonry bit, but you can also make a hole in the bottom of the piece when you're packing the mix in.

Plastic Comparison:

It's interesting to see the difference between these two types of plastic. On the left is PLA (Polylactic acid), which is biodegradeable, and has a more matte surface finish. On the right is PET (Polyethelyne terephthalate), which has a very glossy finish. Different types of plastics will give different surface finishes, even if they both look perfectly smooth.
