Did you know a 60-pound bag of concrete mix only costs about $3? This makes DIYing concrete items so affordable! And with spring finally arriving, DIY concrete planters are a stylish and cheap way to spruce up your patio. I was excited to try a couple different shapes, and I’ve created a template so you can create them, too.
I also launched my YouTube channel! You can subscribe here. New DIY videos will be uploaded every Saturday!
Choose your shape. Trace or draw it onto poster board. If you’re looking to do a triangle or dodecahedron, you can grab the template here, but you can create any shape you’d like! Orange juice cartons make great pre-made molds if you’re looking to save a bit of time.
Cut out your shape and score the edges that you’ll be folding. I used a razor and ruler for this, and it worked like a charm.
Tape it up. For the triangle and dodecahedron, I used duct tape. I switched to packing tape for the concrete base vase because the duct tape and I were not getting along.
Mix your concrete. Use a 4:1 ratio with four parts concrete to one part water. Mix until it becomes the consistency of peanut butter.
Pour the concrete into your molds. Tape to release air bubbles. If you’re adding a candle or planter shape, now it the time to add it. Weigh it down with pebbles or stones or it’ll float up as evidenced in my video!
Let dry 24-48 hours. In the video, I only let it dry for 24 hours, and although it was dry, it wasn’t cured. I suggest giving it 48 hours before moving to the next step.
Remove from the mold. I used a razor blade and went slow, as you’ll see in the video. Some molds are easier than others, so don’t get frustrated if it seems like it’s taking a while to de-mold.
Sand down any rough edges. If you made a concrete base vase, sand down the bottom so it sits flat.
Paint if desired.
And That’s It!
