Method for Shading Mortar with This Mysterious Plaster

Mini planters made of colorful plaster! It’s a smart and colorful DIY that you have to try!

I used to make plaster from the Parisian craft quite often, but more recently I switched to concrete for projects that I would have already done with plaster. It’s exactly the same process and I love the look of the concrete, so it was logical.

BUT some time ago I was wondering how I could add paint to the plaster for some mini planters that I wanted to make. I did some research online, but I didn’t find a solution anywhere.

Probably because the powdery consistency of the plaster is important enough to apply it correctly, etc. So it’s not just about throwing away acrylic paint and calling it a day.

And yes, it is true that I could just paint them once they are fixed, which I have already done. But I wanted the color to be part of the material, not an afterthought reflection. The texture is different, etc., etc.

So, after a few experiments, I landed on something that actually works! It stains the plaster in almost any color you want, without changing the consistency of the plaster. And now that I get it, I wanted 1) wanted to share it with you in matter you want to try this out for yourself. And 2) I will use this technique much more than necessary. Haha.

Click on the secret ingredient that makes this process possible AND on my simple tutorial to make pastel mini planters for cacti and succulents.

Necessary materials for mini planters

  • Plaster powder (available on Amazon -also known as Paris plaster)
  • Tempera color powder – This is the SECRET INGREDIENT (many options on Amazon, I used this brand, but all of them will work)
  • Silicone Shot Glass Molds (this is exactly what I used, but there are many more on Amazon)
  • Matte base (for sealing plaster)
  • Brush
  • Sandpaper (fine-grained)

Where to Buy plaster from Paris

If you’d rather not buy Plaster of Paris on Amazon, there are plenty of other places where you can find this affordable craft material.

As a rule, you can find plaster of Paris on the spot in craft shops and art supply stores such as Joann’s, Michaels and Dick Blick. Sometimes it is in the field of children’s crafts. But you can also find plaster of Paris in the stores of renovation, such as Lowe’s and Home Depot, as well as in places like Walmart and Target.

Some of them are also available online, so I linked them above just in matter.

Where to find rubber molds for plaster

There are so many options out there. But any silicone or rubber mold will work well, whether it is intended for food or crafts. Just make sure that if you use a food mold for crafting, it will be left for crafting only after that. Do not go back to the use of food after using it for plaster.

So, for example, I used silicone shot glass molds to make these mini planters, as they fit perfectly with what I was looking for. But they also use ice cube molds, chocolate molds, etc. or just skip the food molds all together and go straight to the artisanal molds that you can find everywhere on Etsy from independent sellers.

What else can I use as a plaster mold?

They are also not limited to the use of silicone or rubber molds for gypsum projects. You can also use recyclable items around your house, such as milk cartons or thin plastic containers made from individual cups of oatmeal, yogurt, macaroni and cheese, etc.

You can even use something like a sending hose like I did for THIS DIY concrete vase. Just follow the instructions in this tutorial and replace the concrete with gypsum sand and always use the cooking spray.

There are endless possibilities for plaster from the Parisian craft.

How to Make Colored Plaster

With a ratio of 5 to 1, pour 5 parts of powder plaster into a medium-sized container and add 1 part of powder plaster to the bowl. Stir together until a uniform color is obtained.

FYI – you could probably use less tempera powder than that, to be honest. It really doesn’t take much. The more paint you add, the more vivid it will be, if you add too much, it will eventually lead to a bad grip of the plaster or not at all.

How to make mini planters from colored plaster

1. Once you have mixed the colored plaster that you want to use for this handmade plaster from Paris, you can start with the mini planters.

2. Stir the water into the bowl while stirring until you reach a consistency similar to the pancake batter (slightly thicker than that is still fine).

The plaster is fixed very quickly, so you need to work quickly.

3. Pour the mixture into a silicone mold or pick it up with a spoon.

Gently blot the filled molds on a flat surface to squeeze out the air bubbles, then set aside until they harden (1-2 hours should be good).

4. As soon as they are completely hard to the touch, remove the mini planters from the mold one by one.

5. Use a fine sandpaper to sand the bottom of each planet if there are irregularities.

Then, if possible, leave the planters to air dry for 24 hours.

6. Then seal each mini planter with a matte backing, which essentially forms a thin layer of plastic so that they are no longer soluble (important if you put plants in it).

Wait until the matte center dries completely before planting succulents and cacti.

I have found that small, juicy cuttings are perfect for a start-up planter of this size. And if the plant goes beyond the container, you can replant it in a larger version.
