Preparing the Mold

Assemble the fiberglass mold and securely tighten all bolts before pouring.

Ensure the silicone liner is properly seated inside the mold to achieve smooth surfaces and clean edges.

Pouring the Concrete

Mix your concrete to the desired consistency.

Pour evenly into the mold while ensuring the silicone drainage button remains visible. Do not pour above this level, as the button forms the planter drainage hole.

Lightly vibrate or tap the mold to release trapped air bubbles and improve surface quality.

Curing

Allow the concrete planter to fully cure before demolding.

Typical curing time ranges between 24–48 hours depending on your concrete mix and environmental conditions.

Demolding

Begin by removing all bolts from the fiberglass shell.

Carefully separate the fiberglass shell from the planter. If the mold feels stuck, place the nozzle of an air compressor into the built in air release holes and apply pressure to help loosen the shell.

Once removed, slowly peel the silicone liner away from the planter until fully separated.

Finishing Touches

Each planter includes a built in drainage hole.

Light sanding or edge refinement may be performed if desired for a clean finished appearance.

Care and Maintenance

Clean molds after each use using mild soap and water.

Store molds in a cool, dry environment away from direct sunlight exposure.

With proper maintenance, these molds are designed to withstand hundreds of pours and long term production use.
