Saturday: Building the Foundation

Size the Form Panels

  1. Place a plywood sheet on your work surface, and meticulously cut the sides, inset panels, base, and cleats according to the provided dimensions.

Cutting the Molding

  1. Frame the four inset panels with precision. Cut the molding at a 45-degree angle and secure them in place using wood glue and a pneumatic nailer.

Forming the Edges

  1. Assemble the form edges by joining the sides with 2-inch drywall screws, creating a sturdy box structure.

Installing the Drain Dowel

  1. Integrate a 1-inch-diameter wood dowel as a drain hole, ensuring efficient water drainage for the planter.

Attaching Cleats

  1. Center the form on the base, affixing cleats with 1¼-inch screws. Seal corners and joints with latex caulk to prevent concrete leakage.

Sunday: Bringing the Planter to Life

Crafting the Interior Form

  1. Construct an interior form using fiberboard, cutting pieces with a circular saw, and assembling them securely with duct tape.

Mixing the Concrete

  1. Combine a half bag of countertop mix with half a gallon of water, allowing it to slake for 10 minutes. Lubricate the form with oil for easy removal.

Filling the Form

  1. Load the mix into the form, adding a layer up to the top of the drain dowel. Insert the interior form filled with sand to maintain structural integrity.

Curing and Unveiling

  1. Let the mix cure for at least 18 hours before unveiling the planter. Remove the interior form and disassemble the plywood structure to reveal your masterpiece.

Finishing Touches

  1. Consider rinsing the planter with warm water and dish soap to remove any residual vegetable oil, providing a pristine finish.
