Nice material

I enjoyed working with this material. The weight of the finished product is heavier than epoxy, which works well for many projects I do.
I do find it is harder to mix than epoxy, but there is a longer work time, so just take your time and make sure it is all mixed. I used a silicon spatchula to mix it and pressed any lumps against the side of my container while mixing.
When colouring the Stonelith, the colour doesn't get as dark as with a mica in epoxy, but the base of the material is a white colour not clear like epoxy, so the colour is lighter in hue.
All in all, this is fun to work with and I have made a few items that are as strong or stronger than my epoxy items.
Thank you, I will be purchasing again.

Stonelith is our newest addition to the Nerpa product family. It is a two-component polymer/mineral composite resin system - an extremely versatile material for casting, moulding, and laminating aesthetic, creative, and structural pieces.

Stonelith can be moulded and shaped to produce a wide variety of 3D artistic creations, such as small crafts, design furniture, ornamental components and concept prototypes. Stonelith's ability to capture intricate details positions it as a premier option for crafting detailed and complex pieces of art.

Upon blending, it produces a robust and adaptable substance that can be moulded or laminated into an array of designs, surpassing the applications of traditional compounds.

Key features: 

  • Water-based polymer technology is safer for the environment than solvent-based alternatives
  • Ammonia free
  • Fire resistant
  • Impact resistant
  • Stonelith can be pigmented with Stonelith Colourants to get a unique appearance
  • It can mimic materials such as stone, concrete and wood. Compatible with epoxy resins once cured
  • Resistant to UV rays

Application Examples:

  • Decorative crafts such as vases, trays, candle holders and others
  • Terrazzo effects
  • Furniture
  • Complex geometry prototypes
  • Expanded polystyrene (EPS) coating projects
  • Lightweight construction 
  • Wall panels
  • Contoured canvas art
  • Many others!
We formulated the Stonelith without containing VOCs and ammonia to provide you with a safer, quality material. Stonelith stands out from the alternatives because it is easier to use, thanks to its extended working time. To enhance air release, we introduced a nanoform additive into a formula that boosts the material's self-defoaming properties.

    Safety and precautions: 

    Stonelith is considered a safer option than epoxy resin, mainly due to the lack of skin sensitization and skin corrosion issues associated with epoxy. Our water-based polymeric material is considered a non-hazardous liquid when used as instructed.

    We strongly encourage you to always wear a mask when working with the particulate matter (base) of the Stonelith. Inhaling dust for prolonged periods of time can lead to irritation of the respiratory system and other related issues. Please refer to the Safety Data Sheet for further information.

    It is also important to note that the reaction between the base and the polymer is exothermic. You should NEVER encase any parts of the body in Stonelith, as it can lead to burns and injuries.
