How to Make Concrete Planters: 14 Steps
Step 1: Gather materials
You will need the following materials to start making concrete planters:
– Cement mix
– Water
– Sand (optional)
– Trowel or squeegee
– Plastic containers in various sizes (for shaping the planter)
– Cooking spray or petroleum jelly (to lubricate the containers)
– Gloves
– Safety goggles
– Dust mask
Step 2: Select your planter molds
Choose plastic containers of different sizes, ideally a smaller one to fit inside a larger one. The gap between them will determine the thickness of your planter’s walls.
Step 3: Prep your molds
Apply cooking spray or petroleum jelly to the insides of the larger container and the outside of the smaller one. This will make it easier to remove the concrete once it has set.
Step 4: Mix the concrete
Follow the instructions on your cement mix package to create a suitable mixture. Add sand if you want a smoother finish on your planter.
Step 5: Pour the concrete into the mold
Fill the larger container with mixed concrete, leaving room for the smaller container.
Step 6: Insert the inner mold
Place the smaller container inside and press down gently until you reach your desired planter thickness.
Step 7: Weigh down the inner mold
Place weights, such as rocks, into the smaller container to hold it in place.
Step 8: Eliminate air bubbles
Tap the outer container’s sides with a rubber mallet or your hands to help release air bubbles trapped in the concrete.
Step 9: Allow it to cure
Let your concrete planter rest undisturbed for at least 24 hours so that it can properly cure and strengthen.
Step 10: Remove from molds
Gently remove your planter from both containers, using care not to damage its structure.
Step 11: Sand the surface (optional)
If desired, smooth out rough edges or imperfections using sandpaper.
Step 12: Add drainage holes
Drill small holes into the base of your planter to enable proper drainage for your plants.
Step 13: Seal your planter (optional)
Apply a concrete sealer to protect the planter from moisture and stains, as well as to provide a smoother finish.
Step 14: Plant and enjoy!
It’s time to add soil and your favorite plants to your new concrete planter! Place it in a spot where it complements your landscape and enjoy its unique appeal.
Now you know how to make your own concrete planters in just 14 steps. With a little creativity and effort, you can create stunning planters that will enhance your garden or outdoor space.
