Silicone Mould System
Reusable moulds for gypsum and cement — flex, release, cast the same shape again.
Specifications, explained
The numbers that decide how a cast behaves — and what to watch for at each step.
Mould & release
- Material Flexible silicone
- Flexes away from the cast, so fine detail and undercuts survive demoulding.
- Release No release agent
- Non-stick as it comes — no wax, no oil, nothing to wipe off the piece.
- Shapes Discs, trays, coasters, dishes, tealight holders
- One mould per shape, each sized so a single batch fills it.
Timing & use
- Demould 15–30 minutes
- When the face stops feeling tacky, a light flex and the piece lifts out.
- Reuse Rinse, dry, cast again
- Water alone is enough; dry it fully before the next pour so water does not thin the mix.
- Care Store flat, out of the sun
- Heat and UV are what age silicone — keep it out of direct sun when it is not in use.
Finished piece
- Detail Sharp edges, clean corners
- The mould releases the piece instead of dragging it out, so edges stay crisp.
- Faces Glossy face, matte back
- The face against the mould comes out the smoothest — that is the side to keep up.
- Lifespan Many casts per mould
- Silicone stretches long before it tears, as long as it is stored flat.
