Jesmonite is a water-based composite material made from a mineral powder and an acrylic resin. It’s used to create everything from decorative objects to art and functional design pieces. Think of it as a mix between plaster and plastic – but stronger, more durable, and more versatile.

Yes – compared to many traditional materials: • Water-based (no harsh solvents) • Low VOC • Safe to use indoors

No, it is non-toxic when used correctly. However: • Avoid inhaling the powder • Use gloves during extended use

AC100 → Best for: • Home decor • Candle vessels • Small objects AC730 → Best for: • Outdoor use • Frost-resistant pieces • Stone-like finishes

Standard ratio (AC100): • 2.5 parts powder • 1 part liquid Tips: • Mix thoroughly (no lumps) • Work quickly – working time is ~5–10 minutes

• Demolding time: 20–30 minutes • Full cure: 24 hours

Common causes: • Mixing too fast • No vibration • Mix too thick Solutions: • Tap or shake the mold • Brush a thin layer into the mold first • Improve your pouring technique

Yes! • Use Jesmonite pigments • Mix into the liquid before adding powder You can also: • Create marble effects • Make color washes using pigment + sealer

• Use high-quality silicone molds • Avoid introducing air • Post-process with: • Wet sanding (fine grit) • Sealer

Yes, especially for: • Candle vessels • Vases • Objects exposed to water Pro tip: 👉 For best results: 1. Dilute sealer with water for first layers 2. Apply multiple thin coats 3. Finish with one undiluted layer

• Matte → natural, stone-like • Satin → soft sheen (premium look) • Gloss → shiny, more plastic-like

Yes, but: • Use AC730 • Seal properly • Avoid constant water exposure

Yes, but: • Must be properly sealed • Always test your vessels (wick testing)

Common causes: • Uneven sealer application • Too much pigment • Poor mixing

Yes: • Sanding → gives a stone-like finish • Drilling → works well after full cure

• Stronger than plaster • Less brittle • Can be reinforced with fiber or mesh

Yes: • Mix two colors separately • Pour together without overmixing • Creates a natural stone look

Yes: • Acrylic paint works best • You can also: • Create washes • Add patina effects

• Wrong mixing ratio • Working too slowly • Poor mixing • Skipping sealer

• Clean with water immediately after use • Once cured → must be scraped off

• Very durable • Less prone to cracking than plaster • Maintains color and shape over time
