I love jesmonite much more than epoxy, and I truly believe jesmonite is much more beginner-friendly. Let me show you how to use jesmonite in an easy way and we will make a colorful jesmonite tray in just 40 minutes.

  • Jesmonite or an alternative (this eco resin is available in the US)
  • Jesmonite Pigments (colors you want to use). For my tray, I’m using pink and purple powder pigments.
  • Mold, I’m using this tray mold.
  • Cups and stirring sticks
  • Digital scale
  • Wax
  • Tweezers or toothpick
  • Sandpaper

For the regular oval tray, I used approximately 250 gr of Jesmonite powder base and roughly 100 ml of liquid base.

Jesmonite alternative I have
  • If you are using original Jesmonite your ratio will be 2.5 parts of powder base to 1 part of liquid base. If you will use plaster, eco resin, or any other alternative follow the guidelines on the package.
  • for a regular tray, you will need approximately 250 gr of powder base and roughly 100 ml of liquid base.
  • 20gr of the pigment per 1 kg of jesmonite/mixture. Follow this ratio for bold colors, for more pastel tones I used less pigment.
  • Mix very well. It looks all good on top, but at the bottom of the cup, there will be still unmixed powder, trust me.
  • Have a toothpick to make sure there are no bubbles in the mix
  • Remember the visible top for you when you pour the tray will be the bottom of the tray.
  • You can always make your own molds using casting materials and silicone.

Step 1 – Mixing the colors

Make sure your mold is clean, the work surface is covered and clean. If yes, you are ready to create!

I use digital scales to weight ingredients

Shake the liquid part, and pour the liquid base into one cup and weigh it. Add pigment to the liquid and mix. Weight the 2,5 times powder base in a separate cup.

Pour the liquid into the dry part.

I’m using the two colors so I first had 50 gr of the liquid part prepared for the purple color, and the other 50 gr in a separate cup for the pink color. I measured in two other separate cups 125 gr of powder base in each.

Liquid and dry part of the mix

I actually added pigment to the dry part and then poured liquid and it mixed well. But the brand calls for adding pigment in the liquid part.

You can mix it with a wooden stick, I used my square-shaped palette knife. Make sure there are no lumps:

Step 2 – Pour the colors

This is your total freedom!

You can pour the jesmonite mix and swirl, you can make circle motions while pouring from both colors at the same time, you can use many colors, and you can pour one solid – anything you want!

As I had two colors, I just wanted them to meet halfway, so I just placed my two cups at the opposite edges and poured.

But I want to show you that you can also do swirls, so I did some at the back of my tray, it can look like this:

Don’t forget their bubbles

As you can see there are some lumps and air bubbles, I will remove them all with a toothpick. Some lumps I will sand when the tray is dry.

Do it quickly before the jesmonite sets.

Step 3 – Demold

Jesmonite is so quick-setting! One more thing I love about it. Within 30-40 minutes the tray was ready to get out of the mold:

Only after 30 min I noticed that the edges were hard dry already!

You should remove the tray from the mold and let it cure fully. I leave it overnight. This was my first go and you can see I still left out some bubbles:

But I love the colors and how the tray turned out!

If you want, at this step you can decorate and draw on jesmonite tray with paint pens or acrylics.

Keep the leftover Jesmonite mix

By the way, have you seen amazing terrazzo trays made with jesmonite?

You can do one as well.

Simply keep the leftover colors to dry and then break them into small pieces! Next time you can mix them in and you will get some nice results.

Step 4 – Sealing

For jesmonite, we use regular beeswax as a sealant. Just rub it into the dried tray and it is done!

Your beautiful tray is done! I will be happy to see yours, please send them by email or tag me on Instagram if you post your jesmonite creations.


Can I use acrylic resin instead of jesmonite?

Plaster and eco resins are close alternatives to jesmonite as they are both powdery and have the same characteristics.

They are also easier to manage than resin. Acrylic resin is not the same as the epoxy resin we are using for casting jewelry or making tables.

So I would not use acrylic resin instead of jesmonite if you want to get the same results.

Compare these two trays:

Jesmonite tray

They have a very different look, feel, and making process. I believe jesmonite (or its alternatives) to be easier for beginners and faster, and more forgiving, than epoxy resin.

But of course, you can explore your creative side and try everything (like I do!). It brings me so much joy and I hope you learned how to use jesmonite in a very easy way today with me!
