How to Make Concrete Garden Spheres: A Step-by-Step Guide

Concrete garden spheres can add a touch of elegance and sophistication to any outdoor space. Not only are they visually appealing, but they also serve as versatile decor elements that can be used as standalone pieces or in combination with other accessories. Making your own concrete garden spheres might seem like a daunting task, but it is actually quite simple and can be an enjoyable DIY project. In this article, we will provide you with a step-by-step guide on how to make concrete garden spheres.

Materials Needed:
– Concrete mix
– Water
– Large plastic bowl or bucket
– Concrete bonding adhesive
– Rubber gloves
– Dust mask
– Plastic sheet
– Oil or cooking spray
– Heavy-duty nylon gloves
– Concrete mold (i.e., old glass globe light covers, beach balls, or inflatable balls)
– Wire or chicken wire
– Wire cutters
– Sandpaper
– Acrylic sealer or paint

Step 1: Prepare the Work Area
Start by selecting a well-ventilated area, preferably outdoors, for this project. Lay down a plastic sheet or old newspapers to protect the surface beneath your work area from spills and stains. Ensure you have easy access to water for cleanup purposes.

Step 2: Prepare the Mixture
Put on your rubber gloves and dust mask to protect yourself from the concrete dust. In a large plastic bowl or bucket, mix the concrete powder with water according to the instructions provided on the packaging. Stir the mixture thoroughly until it reaches a thick, but pourable, consistency. Add a concrete bonding adhesive to ensure a stronger bond between the mix and the mold.

Step 3: Prepare the Mold
The mold for your concrete garden sphere can be created using various items. Popular options include old glass globe light covers, beach balls, and inflatable balls. If using a glass globe, cover its opening with plastic wrap, securing it tightly with tape. For an inflatable object, inflate it to your desired size. Cut a small hole to pour concrete into, around 5-6 inches in diameter, and cover it with plastic wrap. You can also create a mold with chicken wire by shaping it into a sphere and securing it tightly.

Step 4: Coat the Mold
Coat the interior surface of the mold with oil or cooking spray. This will make it easier to remove the hardened concrete garden sphere later on. Ensure that you cover every area properly, including the openings, and wipe off any excess.

Step 5: Pour the Concrete
Wearing heavy-duty nylon gloves, begin pouring the concrete mixture into the mold through the small hole you created. Fill it up to the top, ensuring that the mix reaches every nook and cranny. Tapping the mold gently, or using a vibrating tool, can help remove air bubbles and ensure the concrete settles evenly.

Step 6: Secure the Mold
Once the mold is filled, securely wrap the plastic sheet around it to keep the concrete from leaking out. Leave the concrete to cure and harden for at least 24-48 hours, or as directed by the concrete mix manufacturer.

Step 7: Remove the Mold
After the curing period has elapsed, carefully remove the plastic sheet from the mold and undo any fastenings or tape holding it together. Slowly deflate an inflatable mold or break the glass on a glass globe to access the hardened concrete sphere. If using a chicken wire mold, carefully cut through the wire to release the sphere.

Step 8: Finishing Touches
Now that you have your concrete garden sphere, use sandpaper to smooth out any rough edges or imperfections. Apply an acrylic sealer or paint to protect the sphere from the elements and add color if desired. Allow the sealer or paint to dry completely before placing the concrete garden sphere in your desired location.

In conclusion, creating your own concrete garden spheres can be a rewarding and fun DIY project. With just a few materials and a little effort, you can craft stunning decorative pieces to enhance your outdoor space. Remember to take the necessary safety precautions, follow the step-by-step guide, and let your creativity shine through.
