JESMONITE® AC300 is a super-cool, eco-friendly casting material loved by craftspeople around the world from jewellery makers to builders, sculptors to interior designers. Non-toxic, easy to use and just soooooo insanely beautiful…we’re totes obsessed.

Made from an acrylic (water-based) liquid resin mixed with a modified gypsum powder, this off-white building material is truly unbeatable and we are ridiculously proud to be THE ONLY Official JESMONITE® Retailer. Buying JESMONITE® from Resin8® guarantees you the real Jesmo deal.

The ultimate chameleon material… use JESMONITE® for casting, intricate detailing in jewellery, homewares & sculptures. Suitable for use by children aged 10+, it’s smooth, tactile, heat resistant and touch dry in 30 minutes! Now what could be better than that?!

We know what…! Through buying JESMONITE® you are making a planet-conscious crafting choice. Yes, it’s eco-friendly in its own right, but we add so much more to that by selling in fully compostable, biodegradable or easily recyclable containers, being a carbon neutral company and doing our utmost to reduce our impact on the environment. Super-green, super-cool.

JESMONITE® AC300 is perfect for beginners! It has a longer working time than AC100 and is the ideal material to start with when you're just beginning your JESMONITE® journey!

  • Contents: 2kg BASE and 800g LIQUID - in recyclable containers
  • Mix Ratio: 2.5 parts BASE : 1 part LIQUID (e.g. 10g powder = 4g liquid | 100g powder = 40g liquid)
  • Stir thoroughly for 2 minutes
  • Working time: 20 minutes (can be doubled using a drop or two of slow-it retarder)
  • Can be thickened using thicken-it thixotrope (for use on curved surfaces)

Top Tips

  • When mixing we like to measure our JESMONITE® liquid first and sprinkle on the base powder whilst stirring constantly. This means less air bubbles and less chance of any mottled effects.
  • To reduce large bubbles spoiling the surface of your creation, use a clean paintbrush to cover the inside of your mould with mixed JESMONITE® before the main pour. Once dry, fill the rest of the mould.
  • JESMONITE® has its own range of colour pigments (how cool is that) although you can also use our neon powders and acrylic inks to give a range of dense opaque colours - remember though that as JESMONITE® is off-white, any colour mixed in will lighten (therefore meaning you will need more colour!).
  • DON'T FORGET - adding our opaque, transparent, metallic or neon resin pigments (which have not been specifically designed for JESMONITE®) will make the colour appear much lighter and could affect the cure of the piece. Now we don't want that do we?!
  • Can be displayed externally when used with a suitable sealer.
  • JESMONITE® has not been tested for food safety - by all means use JESMONITE® for decorative tableware, but please make sure you use an approved food-safe sealant.

It is your responsibility to ensure you have read all of the health & safety information we provide. Take a look at our Health & Safety page for more general info on working with our products
