A few weeks ago I decided finally take on a small project I had been wanting to try. So I gathered my supplies-(lugging around the concrete was a sight I’m sure)-and started making my own concrete planter using a few simple and affordable supplies.
1x 60 lb bag of basic concrete mix— Quikrete or Sakrete ready to use mixtures will work great!
1x Set of Plastic molds- History Stones Cortona Planter.
1x Base mold- Small Base Mold
1x Trowel/ hoe/ or shovel- For mixing the concrete
1x Plastic Tub for mixing- similar to what is shown in the photo below.
1x Can of cooking spray- Used as a lubricant for your mold.
1x gallon- Water!! of course you will need water. I recommend having a gallon or less on hand. You will slowly mix this in until you have the right consistency.
Pour your dry concrete into a large plastic tub and mix in water slowly.
Consistency: Make a fist with the cement. You want it to be at least as thick as peanut butter where it can start to come out the sides of your fingers. However not so think that water is running out.
* Using too much water can lead to cracking around the edges where water has settled once it is finished.
Spray down the inside of your Planter mold and the outside or your sphere mold ( or whatever you are going to use to hollow the center of your planter) with Cooking spray. Pam cooking spray works great- any others brands with the same consistency will work as well!
Use a small trowel or shovel to scoop a few scoops of concrete into your planter mold. Then place the sphere mold in the planter mold and keep filling around the edges. Place water or extra concrete in the sphere to weigh it down.
*It is good to tap and shake the mold a few times throughout your pouring process if you wish to eliminate air bubbles.
Let your concrete set for about an hour. Then rotate or swivel the sphere (or inside mold) so that it is easy to remove once your planter has dried. I recommend doing this at least one more time 12 hours later. You can even take the sphere mold out at that point. Let dry about 24hrs.
Walahhhhh! That’s it.. your done! Remove the sphere and unmold your planter over grass or two pieces of wood (something that will keep it from hitting a hard surface on its way out.) You will be surprised by how easy it is to get out of the mold.
