Cement Planter Molds
The recycle bin is full of cement planter mold ideas! We upcycled the outer plastic shells from LED light bulb packaging.
So if you’re upgrading your light bulbs, save all the packaging – and accessories! In addition to the plastic shell, we also combined it with a standard base adapter from this chandelier bulb packaging. These adapters are the trick to getting this cement planter to stand on its own. But don’t worry, these adapters are also available separately.
Here’s a closer look at the base adapters that allow the cement ‘bulb’ to be screwed into a porcelain lamp holder socket – just like a real light bulb!
Air Plant Stand
To allow the cement planter to stand, use a thrifted porcelain lampholder like the one shown below. You may even have some of these if your basement is unfinished. So don’t forget to save them for cement crafts when you renovate and upgrade your light fixtures!

How Do You Make Cement Crafts?
Step 1 – Prepare Mold
Use any straight side round object, like a film canister or hair spray cap, to create a hole in the top.
Notch out the lip where your round object touches the top of the bulb packaging so you can get it to sit flush. Then trace around it with a marker.
Cut a hole in the top as shown with scissors or a utility knife.
The film canister should be able to slide into the hole to displace the wet cement. That’s what will create the hole in the top for the air plant to sit in.
Step 2 – Grease the cement planter mold
You’ll need a cement release agent so the cement mix doesn’t stick to the mold. An oil-based release agent like petroleum jelly, aka vaseline, is perfect for the job.
Use a piece of cotton to spread a coat of vaseline onto the inside of the mold. If it’s too thick, you’ll see texture when you pour the cement into the mold so a little goes a long way.
As well as the mold, the metal base adapter also gets a light coat of vaseline before it goes into the bottom of the mold. And don’t forget to grease the film canister too.
Then place the base adapter into the cement mold so it sits at the bottom of the light bulb shape.
Step 3 – Seal the Mold
To seal the cement planter mold and prevent leaks, secure all sides of the light bulb packaging with binder clips.
In fact, put them tightly side-by-side so the cement will stay inside the mold.
Step 4 – Create Support for Cement Mold
Cut the water bottle in half, as shown. While the bottom half is used to support the mold, ready to receive the cement, the upper half is used as a funnel. It will help direct the cement into the mold.
Step 5 – Mix and Pour Cement
For the cement mixture, the ratio is one part water to four parts cement. Our air plant holder uses 8 ounces of power and 2 ounces of water.
Mix the Rapid Set Cement All with water according to package directions, stirring for only a minute until the water is well absorbed.
Pour the cement into the makeshift plastic bottle funnel.
Before inserting the film canister, tap the side to release air bubbles (I did it after on the video).
Now insert the film canister and tape it down. Then let the cement dry for 1 – 2 hours.
With the leftover cement, let it dry in the plastic container. Nothing goes to waste: we’ll use it later as a sanding block.
Step 6 – Release Cement Mold
Take off the binder clips.
Remove the plastic light bulb shell.
The base adapter will likely have a light coat of cement on it.
Break off as much cement as you can.
A metal punch helps remove the rest. Tap it, as shown in the video, to crack the remaining dry cement on the base adapter.
Step 6 – Sand
Now use the cement puck you made from the leftover cement to sand the ridges on the sides of the cement planter.
Once sanded, screw your DIY light bulb planter into the porcelain base and pop an air plant right into the top.
Didn’t we tell you cement craft molds are easy? And using recycled light bulb packaging is easy on the pocket book too! Now that you know what to use as a mold, a grouping of these air planters would look great lined up on a window sill.
FAQs – Working with Cement Planter Molds
Here’s a few FAQs and recap about crafting with cement.
Mixing Cement for Crafts
What Kind of Cement is Used for Crafts?
The best cement for crafts is one that’s strong and fast setting. For crafting, you also want a cement mix that will give you a smooth finish like Rapid Set Cement All. Cement All is a multi-pupose product used for levelling and concrete repair. But its quick set time and low shrinkage make it idea for cement crafts like our diy cement planter.
Mold for Cement Planter
You don’t really need fancy cement molds for crafts! Sure, you can spend money on silicone molds. But our cement planter mold is upcycled from the plastic waste packaging that comes with LED light bulbs. Easy AND cheap is always a win-win!
What’s the Difference Between Cement and Concrete
Some tend to use the term cement and concrete interchangeably, However, cement and concrete are not one in the same. In fact, cement is an ingredient that’s used in concrete mixes.
What Can I do With Spare Concrete?
Let leftover cement dry in the bottom of the container you mixed your cement craft in. Once dry, you can pop it out and use it as a sanding block to smooth the seams of your cement planter.
