DIY Colored Plaster of Paris Mini Planters
Mini planters made of colored plaster! It's a clever and colorful DIY that you've gotta try!
After some experimenting, I landed on something that actually works for creating colored plaster! It will tint plaster nearly any color you want without changing the consistency of the plaster.
Yield: 40 planters or more
Cost: $15
Materials
- plaster powder available on Amazon - also know as Plaster of Paris
- powdered tempera paint - THIS IS THE SECRET INGREDIENT lots of options on Amazon, I used this brand but any will work
- silicone shot glass molds this is exactly what I used, but there are loads more on Amazon
- matte medium to seal the plaster
- paint brush
- sandpaper fine grit
Instructions
- Once you have mixed together the colored plaster you'd like to use for this Plaster of Paris craft, you can get started with the mini planters.
- Stir in water to the bowl, while stirring, until you reached a consistency similar to pancake batter (a little thicker than that is still fine though).
- Plaster sets very quickly, so you'll need to work fast.
- Pour mixture into silicone mold or scoop it in with a spoon.
- Gently tap the filled molds on a flat surface to get out any air bubbles and then aside until hardened (1-2 hours should be fine).
- Once they are completely hard to the touch, remove the mini planters from the mold one at a time.
- Use a fine sandpaper to sand down the bottom of each planet, if there is any unevenness.
- Then let the planters finish air drying for a full 24 hours, if possible.
- Next, seal each mini planter with a matte medium, which basically creates a thin layer of plastic so they will no longer be soluble (important if you're going to put plants in them).
- Wait for the matte medium to dry completely before planting succulents and cacti.
- I found that small succulent cuttings are perfect for this size starter planter. And when the plant outgrows the container, you can replant it in a larger version.
