Hypertufa Design with Colleen Dieter

Colleen’s instructions:

• Wear Gloves. Cement is caustic.
• Mix equal parts perlite, peat moss and Portland cement in large container or wheelbarrow.
• Slowly begin to add water and mix until mixture is the consistency of cottage cheese.
• Coat containers with cooking spray.
• Pour mixture into the outer mold until it is an inch or more thick. At this point you can
  push a cork or dowel into the bottom of the mixture to create drainage holes if you are
  creating a planter.
• Put a smaller bowl on the inside of the big bowl. Fill the inner mold with sand or water to steady it. Pack mixture in tightly. Cover the containers with plastic.
• After 24 hours remove the inner mold. Use a rubber mallet if needed to knock the
  container loose from the mold. Replace plastic.
• After 36 hours remove outer mold.
• After removing molds, you can drill holes using a masonry bit in the bottom of the
  container for drainage if needed. Use a planer file or sand paper to smooth out any rough
  edges.
• Re-cover containers with plastic and let sit for several weeks in order to finish curing.
