What is plaster of Paris?

Plaster of Paris is a quick-setting powder made from the soft, white (ish) mineral gypsum.  There are two types of plaster of Paris that you are likely to come across: loose powder, and bandage form. Plaster of Paris is commonly used as a building material, as well as in dentistry and orthodontics. It’s used to make plaster casts for broken bones, sculptures, decorative elements, and of course, in the craft industry.

Why is it called plaster of Paris?

It is called plaster of Paris, because of the abundance of the mineral gypsum near Paris in France. After the Great Fire of London in 1666, Parisians covered many of their wooden walls with plaster, at the order of the King, to protect the buildings from fire damage, should a disaster like that ever hit the city. This is because plaster is non-combustible.

It required large-scale mining of gypsum, and due to its abundance near Paris – it became known as plaster of Paris. Paris subsequently became the centre of plaster production in the 1700s. Historically, the use of plaster dates back to around 9000 years and has been used by the ancient Egyptians, Greek and Roman civilisations!

Where to buy plaster of Paris moulds, kits and supplies?

So – where to buy plaster of Paris? Thankfully, it’s not hard to come by and you can pick up both the powder and bandage types at most DIY stores or craft stores. It’s relatively inexpensive, but it can be messy! If you’re looking for plaster of Paris to buy, it’s useful to know that the bandage form is also called modroc.  You can buy plaster of Paris from these places:

How to use plaster of Paris

Advertisement

Step 1

First, protect your workspace. Plaster of Paris can get quite messy – it’s a fine powder that can get everywhere! Old newspaper or plastic sheets are good if you have any. Get your moulds ready, and set to one side.

Step 2

The ideal ratio to use is 2:1. That means two parts plaster of Paris to one part water. Measure out your water first, and pour it into your mixing container.

Step 3

Next, measure out twice as much plaster of Paris. Put this in a separate container for now, and break part any lumps with a fork or a spoon.

Step 4

Gradually add the powder to the water, one spoon at a time.

If you have a strainer, it’s a good idea to sift the plaster of Paris powder through the strainer, into the water this way. This helps to avoid clumps forming and prevents you from adding too much powder in one place. You’re aiming to get the powder evenly dispersed throughout the water, so add the powder to different parts of the water.

Step 5

Every so often, tap the side of the container to disperse any air bubbles that might have formed in the mixture. We do not want air bubbles – plaster of Paris dries quickly, so air bubbles in the mixture can be transferred to the mould, which will dry in place and weaken the final product.

Step 6

Keep adding the powder until it is no longer being absorbed by the water. It will appear as though the powder is sitting on top of the water.

Now – stir the mixture. Go slowly because we do not want to introduce air to the mixture, as this will form air bubbles.

Step 7

Once the mixture has reached a smooth, creamy consistency, pour it into your mould. Do not wait for more than a few minutes (maximum) as it will start drying and become difficult to pour.

If you have some spare mixture that you’re not going to use – either use it with another mould or dispose of it in the trash can. Please don’t pour it down the drain – because when it dries it will clog the drains and cause a blockage.

Step 8

Put the mould in a safe place – somewhere where it will not be disturbed – and leave it to cure for 48 hours. It will become touch dry after just a few minutes and will appear dry after one hour, but to ensure the inside is dry we need to leave it for 24-48 hours.

Step 9

Once it’s dry (it will feel cold and hard) – turn the mould inside out to reveal your sculpture! Paint your scupture with acrylic paint, spray paint or poster paint, then leave to dry.

Step 10

Finally, varnish your sculpture to add strength (you can get matt or shiny varnish). Varnishing plaster of Paris will also help to prevent accidental chipping. Once dry – find somewhere to display your plaster of Paris masterpiece!

How long does plaster of Paris take to dry?

Plaster of Paris is a quick-drying material, becoming touch-dry within just a few minutes. If you are using it with a small craft mould, you can remove it from the mould within around an hour – however, for best confidence, you should leave it for 24-48 hours to fully cure (dry).

How do you speed up drying time?

You can speed up the drying time for plaster of Paris by using hot water instead of cold water. If you want to do this – have the mould and everything laid out and ready to go, as it will start setting very quickly. Adding salt to the mixture will also speed up the drying time – however, be aware that if you do this, it will weaken the final product and it will become more susceptible to shattering or crumbling.
