Time is precious and that’s why we have the Jesmonite Retarder; so you can use your extra time however you wish to get your mix spot on! It’s also a great product for beginners who are just starting out with Jesmonite to give them time to work through our step-by-step guides with no added pressure. You might even have time to whip up a snack in between working!

You only need to add a teeny tiny amount to your mix. We’d recommend adding 0.02% – 0.1% of your overall mix to slow down your set time, and give you more minutes to play with. It’s important to remember that the retarder will also slow down your set time when your Jesmonite is in the mould, so you will need to leave your piece in the mould a little longer than usual to avoid any breakages when removing from the mould.

We can’t guarantee that every piece you make will be perfect, but that’s the beauty of experimentation.
