Drying and Removing the Molds

After pouring the concrete, the molds need time to dry and harden. The drying time for concrete planters can vary depending on the type of concrete used. However, it is generally recommended to leave the molds undisturbed for a minimum of 12-24 hours. This allows the concrete to set and achieve the desired hardness.

To determine if the concrete is ready for removal, gently touch the surface. If it feels dry and hard to the touch, it is likely that the concrete has sufficiently cured. Keep in mind that drying time may be affected by factors such as temperature and humidity, so it’s always a good idea to check the hardness of the concrete before proceeding.

When the concrete is dry and hardened, it’s time to remove the molds. Carefully peel off the cardboard molds from the concrete, taking care not to disturb or damage the planter. Start by loosening the edges and gradually work your way around the mold until it is completely detached. The smooth surface of your geometric concrete planter will be revealed once the molds are removed.

Drying and Removing the Molds

Recommended Drying Times for Different Concrete Types

Concrete Type Minimum Drying Time
Standard Concrete Mix 12-24 hours
Rapid-Setting Concrete Mix 4-6 hours
High-Strength Concrete Mix 24-48 hours
Self-Leveling Concrete Mix 24-36 hours

It’s important to note that the drying time may vary depending on the specific brand and instructions of the concrete mix you are using. Always refer to the manufacturer’s guidelines for the most accurate drying time.

Sanding and Finishing the Concrete Planters

To achieve a smooth surface on your DIY geometric concrete planters, sanding is crucial. This step helps to refine the texture and create a polished finish. Follow these steps to sand and finish your concrete planters:

Sanding the Concrete

Start by using rough-grit sandpaper, such as 80 or 100 grit, to sand the surface of the planter. Apply gentle pressure and move the sandpaper in circular motions or back and forth to smooth out any imperfections, rough edges, or uneven areas. Be sure to sand all sides of the planter for a uniform finish.

Tip: Remember to wear protective gloves and a dust mask to avoid inhaling any dust particles.

After sanding with the rough grit, switch to a finer-grit sandpaper, such as 220 or 320 grit. Repeat the sanding process with the finer grit to further refine the surface and achieve a smoother texture. Keep sanding until the concrete feels smooth to the touch.

Gluing a Wooden Top

For an added decorative touch, you can attach a wooden top to your concrete planter. Choose a wooden piece that complements the overall design and style. Apply wood glue to the bottom of the wooden top and carefully position it on the planter, ensuring it sits flush with the concrete surface.
