How to Use Cement Flower Pot Molds
- 1). Coat the inside of the cement flower pot mold with a release agent. Commercial products work, but you can also use vegetable oil, petroleum jelly or a blend of castor oil and denatured alcohol. To make the castor oil/alcohol mix, combine 2 oz. of castor oil with 16 oz. of alcohol. Apply the mixture with a spray bottle.
- 2). Mix concrete topping mix in a bucket with water following the ratios indicated on the concrete package. Topping mix is a good choice for cement flower pots as it does not contain stones and gives your flower pots a smooth finish. An electric drill with a paddle drill bit works well to mix the cement, but you can also use a small shovel or wooden spoon.
- 3). Pour the mixture into the cement flower pot mold. Tap the sides of the mold to release any air bubbles that may be trapped. Let the cement dry in the mold for 48 hours.
- 4). Flip the mold upside down on a sheet of plywood to remove the flower pot. Some aluminum molds require disassembling to remove them from the dried cement form. Allow the cement flower pot to sit for seven days before planting anything in it. This gives the concrete time to cure completely.
