How to Make DIY Cement Planters

Pouring cement into planter mold
  1. Prepare the mold
    Spray the inside of the mold with cooking spray or mold release.
  2. Mix the cement
    Combine cement mix and water until it reaches a thick, pourable consistency (like pancake batter).
  3. Pour the base layer
    Pour cement into the mold to form the bottom of the planter.
  4. Insert the inner mold
    Press the smaller mold into the center to create the planting space. Weigh it down if needed.
  5. Fill the sides
    Pour cement around the inner mold until desired thickness is reached.
  6. Tap to remove air bubbles
    Gently tap or shake the mold to release trapped air.
  7. Let it cure
    Allow the cement to cure for 24–48 hours (or per package instructions).
  8. Demold carefully
    Remove the mold slowly once fully set.
