How to Use

Measure: Take equal portions of Part A (white) and Part B (orange) by volume or weight.
Mix: Knead the two parts together by hand for 1–2 minutes until the putty is a uniform orange color with no white streaks remaining. Work quickly — you have 3–5 minutes of working time.
Press: Press the mixed putty firmly around or over your object, capturing all the detail. Ensure full contact with the surface to avoid air pockets.
Wait: Leave undisturbed for 15–20 minutes at room temperature to cure fully.
Demold: Gently peel the putty away from the object. Your mold is ready to use immediately.
Cast: Pour your chosen casting material (resin, plaster, wax, soap) into the finished mold.

Frequently Asked Questions

How much putty do I need for my object?
As a rough guide, you need enough putty to cover the object with at least 3–5mm of wall thickness on all sides. Small items such as coins, buttons, charms, and small flowers work well with the 60g kit. Medium items such as small figurines, shells, or toy pieces suit the 130g kit. For larger objects, purchase multiple kits.

Can I use this mold putty with resin?
Yes — once cured, the silicone mold is compatible with UV resin, epoxy resin, and polyester resin. Silicone is naturally non-stick so no mold release spray is needed for resin casting. Simply pour your mixed resin into the mold and cure as per your resin instructions.

Is the mold reusable?
Yes — cured silicone putty molds are flexible and reusable. With careful use they can produce many casts. Avoid sharp tools or overstretching the mold when demolding to extend its lifespan.

Can I use this to make candle molds?
Yes — once cured the putty is heat resistant and suitable for pouring wax for small candles, wax melts, and wax seals. Ensure your wax is not poured at excessively high temperatures. For large pillar candles, a rigid-backed mold is recommended alongside the silicone for structural support.
