How it compares
When compared to traditional epoxy resins, Jesmonite is significantly safer to use indoors as it does not emit harmful vapors or require a respirator. Unlike polyurethane casting resins which are purely plastic-based, this material feels more like a ceramic or stone composite. It offers a faster demolding time than most plaster-based alternatives while maintaining a much higher impact resistance and durability for long-term use in 2026.
How to use it
- Measure the liquids and powders at a 1:2.5 weight ratio using a precise digital scale.
- Slowly add the powder to the liquid while stirring continuously to avoid lumps.
- Incorporate pigments or metallic flakes to achieve your desired aesthetic effect.
- Pour the mixture into your silicone mold, tapping the sides to release trapped air bubbles.
- Wait 45 minutes for the piece to set hard before carefully demolding and sanding the edges.
"The finish on my Jesmonite coasters is incredibly professional; it feels like luxury marble but was so much easier to work with than messy epoxy!" — Verified buyer
Sustainability & ethics
Jesmonite is committed to ethical sourcing of its mineral base components and uses a water-based acrylic system that avoids the harsh chemicals found in petrochemical resins. The packaging is largely recyclable, and the brand operates with a high degree of transparency regarding its supply chain and labor standards.
Pro tip
To achieve a high-quality terrazzo effect, let your colored Jesmonite scraps dry completely, break them into small chips, and mix them into a fresh batch of a contrasting color before pouring.
