Mis à jour le

✨ Jesmonite has this little magic power: even when you're starting out, your creations immediately have a stylish look (and frankly, "wow"). No need to be an artist or have a studio: you choose an idea, you test it, you progress... zero pressure .


In this article, you will find ideas for concrete objects to make with Jesmonite , a quick method to get started without complicating your life, and the finishing touches that give a truly professional result.

Jesmonite DIY Kit – JOY!
✨ The JOY jesmonite kit! (the basis to get started)
If you want to get started quickly and create several objects (tray, bowl, coasters…), our kit will get you off to a good start.
  • Ideal for testing several styles (plain, terrazzo, marbled)
  • Perfect if you like “learning by doing”
  • One kit = lots of possible creations

What exactly is Jesmonite?

The "design workshop" finish (no oven, no strong odor)

✨ Jesmonite is a water-based, solvent-free mineral resin , highly valued for creating decorative objects with a modern look (matte, mineral, very “design”).

It can be worked at home , without cooking, and with a very discreet odor (nothing like some resins).
And the most motivating thing: even a first creation can already elicit a "wow" reaction. 😍

Time & drying

⏱️ Jesmonite sets quite quickly: many pieces demold after ~30–40 minutes (depending on size and shape), then they continue to harden afterwards.
The part gains its final strength after approximately 24 hours .
In other words: you can see the result quickly , then let it "finish quietly" over a day.

Specifically: waterproof / food safe?

💦🍽️ Quick tip: Jesmonite is porous . It's not waterproof as is. So:

  • For an item that is kept in a humid area (soap dish, plant pot, etc.), we recommend sealing/varnishing it with a suitable finish.
  • For food use, it is better to stick to decorative purposes (a “pretty” tray yes, direct contact with food no).


The equipment needed to get started with Jesmonite:

"I'm testing" version (the bare minimum)

🧰 For a first attempt, you can start with a very simple base:

  • a bowl (or mixing container) + a spatula
  • a scale (or a measuring cup if your guide gives volumes)
  • one or two silicone molds
  • sandpaper (for sanding the edges)

"Professional rendering" version (small and large details)

✨ If you like the "boutique decor" look, these options make all the difference:

  • pigments, terrazzo effect, gold leaf, inclusions (chips, shavings…)
  • a sealant/varnish suitable for the intended use (especially if there is humidity)
  • small skates (the premium detail under the items)

💡 If you want to get started without running around, our Jesmonite JOY! kit already includes the essentials: Jesmonite AC100, silicone molds, pigments, tools + finishing varnish , with a drying time of 30 to 40 minutes .

Express method: your first Jesmonite item in 7 steps

  1. Protect the table + prepare the mold 🧤
    Place the mold on a stable and flat surface. Also prepare your drying area to avoid moving the object after pouring.
  2. Weigh/measure (according to the instructions) ⚖️
    Follow the proportions indicated (powder + liquid). An approximate dosage can change the setting and the result.
  3. Mix well (goal: smooth texture) 🥣
    Mix until you obtain a homogeneous texture, scraping the sides and bottom of the container well.
  4. Pour + tap to remove bubbles 💧
    Effective tip: start by coating/brushing a thin layer into the mold (especially in the raised areas), then fill it. Gently tapping the mold helps any air bubbles rise to the surface.
  5. Wait → unmold ⏱️
    Depending on the piece, you can often unmold after 30–40 minutes .
    Next, let the creation harden quietly (the final resistance is achieved over time).
  6. Sand (edges + underside)
    Lightly sand the edges and base for a smooth feel and a clean finish (this is often where the “wow” factor appears).
  7. Finish: seal / skates / decoration 🪄
    Add a sealant/varnish if the object is at risk of moisture, glue pads underneath, then have fun with the decoration (terrazzo effect, pigments, gold leaf…).

🫧 Anti-bubbles: simple tips

  • 👆 Tap (and if necessary, gently vibrate) the mold to release the air.
  • 🖌️ “Brush” a thin layer into the mold before filling (especially in the corners/reliefs)
  • 💧 Pour in a thin stream, slowly: this gives the microbubbles a better chance to burst.

What to do with Jesmonite? 8+ craft ideas

Here are some concrete, feasible and very satisfying ideas, even if you are a beginner.

1) Seashell dish (jewelry trinket tray ✨)

Difficulty: easy
Time: 10–15 min preparation + unmolding (depending on setting time)
Mold: silicone "seashell" mold
Tip for a stunning finish: pearlescent pigments + well-sanded edges (that's what gives it that "boutique" look).
Suggested use: jewelry catch-all, key dish, small decorative item on a shelf.

2) Coasters / beer mats (terrazzo effect)

Difficulty: easy
Time: 10 min + unmolding (depending on setting time)
Mold: round/square silicone mold (coaster size)
A great-looking tip: terrazzo "chips" + 1 dominant color (the less you mix, the more stylish it is)
Suggested use: set of 4 assorted, DIY gift, table decoration.

3) Tray (entrance / coffee table / desk)

Level: easy to intermediate
Time: 15–20 min + unmolding (depending on size)
Mold: tray mold (oval, round or rectangular)
Tip for a stunning finish: soft marble effect (2 colors max) + varnish/sealer if used in wet areas (plants, bathroom, etc.)
Suggested uses: entryway “catch-all” tray, desk organizer, candle + perfume holder.

4) Candlestick 🕯️

Difficulty: easy
Time: 10–15 min + unmolding (depending on setting time)
Mold: silicone "candle holder" mold (simple or designer shape)
A great-looking tip: a duo of colors (e.g., neutral base + pastel touch) + minimalist shape = instant boutique effect
Suggested use: as a duo on a table, on a shelf, or as a mini gift (candle holder + candle).

5) Flowerpot (mini or medium) 🪴

Level: Intermediate (thickness + strength)
Time: 20–25 min + unmolding (depending on size)
Mold: silicone mold for a plant pot cover / cylindrical pot
A great finishing tip: apply a sealant to the inside if the object is at risk of exposure to moisture (watering, condensation). Jesmonite is porous, so this protection will prolong its lifespan.
Suggested uses: mini plant, pencil holder, brush storage.

6) Jewelry (pendants, earrings, rings) 💍

Level: Intermediate
Time: 15–20 min + unmolding (small pieces)
Molds: mini molds (pendants, geometric shapes, small drops…)
Tip for a great finish: clean molds + clean drilling + a thin (and even) varnish for a smooth and durable result ✨
Bonus: play with soft pigments, the mini terrazzo effect, or a very light gold leaf.

7) "Catch-all" dish (keys, change, earphones) 🗝️

Difficulty: easy
Time: 10–15 min + unmolding (depending on setting time)
Mold: simple bowl (round, oval, rectangular) or trinket tray

Suggested uses: entryway catch-all, jewelry tray, desk dish for small items.

8) Paperweight / decorative object (freeform) 🪄

Difficulty: easy
Time: 10–20 min + unmolding (depending on shape)

Suggested use: paperweight, decorative object on a stack of books, light doorstop (depending on weight).

Finishing touches: what transforms a DIY Jesmonite into a “wow 😍”

Sanding (the secret to clean edges)

✨ If you only do one thing: lightly sand it . This is often what transforms a piece from a "nice DIY" into a "decorative object".

  • When? Wait until the piece is fully hardened (jesmonite gains its strength after ~24 hours).
  • How? Start “medium”, then finish “fine” (e.g. 240 → 400).
  • Pro tip: dust between two grains to keep a clean surface.

Sealant/varnish: when and why

💦 Jesmonite is porous : it is not “naturally” waterproof. Sealers provide water and stain resistance.

Seal it, especially if the object is located in an area:

  • bathroom (soap dish, bowl near the sink),
  • kitchen (splashes),
  • plant pot cover (watering / condensation).

👉 And if the piece is to go outside (or be exposed), a protection system is recommended.

Pads underneath: the premium detail

🟤 Little skates change everything:

  • They prevent scratches on furniture.
  • stabilize the object,
  • give a “boutique” finish.

Tip: place 3 or 4 under trays, coasters and candle holders (after sanding + sealant if you use it).


Common mistakes with Jesmonite

Bubbles / small holes → tap + pour in a thin stream 🫧

The bubbles arrive quickly… but are very easy to manage.

  • Before filling : pour a little mixture and brush into the raised areas/corners, then tap the mold .
  • During pouring : pour slowly , in a thin stream to help the microbubbles burst.
  • Next : tap again (some makers also do a light “lift & drop” to remove the bubbles).

Unmolding too early → patience + timing marker ⏱️

If you unmold too quickly: crumbly edges, marks, piece that “gets damaged” when sanding.

  • Simple guideline: let it set for about 30–40 minutes (variable depending on conditions), then unmold.
  • Next: allow the piece to complete its curing (full strength ~24 h) before sanding/sealing.

Misuse (water/food) → suitable finish 🚿🍽️

  • Water/humidity : sealant recommended, as Jesmonite is not inherently waterproof.
  • Food : the brand indicates that its products have not been tested “food safe” ; if you want this type of use, you should inquire about suitable sealers (and remain cautious).
