Description
Nerpa Stonelith Composite Mix
Stonelith by Nerpa Polymers is the 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. Each package contains Part A Mineral Composite and the Part B Liquid Activator.
Sizes:
- 840g (0.84kg) – combined weight Part A & B
- 3010g (3.01kg) – combined weight Part A & B
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
- May 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!
Stonelith is formulated without containing VOCs and ammonia to provide you with a safer, quality material. It stands out from the alternatives because it is easier to use, thanks to its extended working time. To enhance air release, a nanoform additive has been added 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. The 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). 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.
