Mold Care Information and Instructions


All molds are made of platinum silicone to ensure longevity and durability. To make your silicone molds last as long as possible, please follow these care guidelines.

  • Prepping molds: remove any dust or lint by using the sticky side of packing tape. Make sure to apply only light pressure because too much pressure can cause indentations in the molds. A light coat of mold releasing spray can be used to help with the demolding process.
    • DO NOT DRAG OR RUB anything on the molds as this can scratch the molds and leave permanent damage.
  • Using molds: after adding resin to the mold, please absolutely stay away from using heat to remove bubbles. This will cause the mold to fuse with resin and the mold will tear apart when demolding. Here are some tips regarding bubbles in resin (We know! We all hate them :D)
    • After pouring resin, lightly spray alcohol on the resin to pop bubbles. Be careful not to spray alcohol on the mold because it will dry out the oil in the mold.
    • Use low viscosity resin: bubbles rise to the top much easier with low viscosity resin. However, please note that the slower the resin cures, the faster molds lose their shine.
    • If you have to use thick resin and absolutely have to use a torch, do that in a separate container (for example, a cheaper silicone mold) and torch it there. Then pour the torched resin into your mold.
    • Pour low. The shorter the distance that the resin has to travel, the fewer bubbles are created during pouring.
  • Cleaning and storing: after demolding, normally the mold is clean. Wrap the mold in a plastic wrap (or use a Ziploc bag) and store in a cool and low humidity area. If you need to clean the mold, clean gently with soap and warm water, let dry and wrap it with plastic wrap for storage.

Our molds are made to last, however, molds will degrade over time/usage. There are many factors that determine how fast a mold degrades. Here are several things to take into consideration:

  • Heat wears molds out. Using a torch on molds will damage them. Please stay away from using heat on molds!
  • Slow curing resins (especially those that take over 24 hours to cure) place greater stress on molds.
  • Mold releases extend a mold's life.
  • Pouring thicker than the resin's recommended depth may damage molds due to heat from the exothermic reaction.
  • Bubbles formed on the surface of a mold (especially 3D molds) can scrape the molds during the demolding process. Please make sure that there are no bubbles on mold's surface.
  • Overstretching molds might cause permanent damage to them.

...and many more. Even though these are high quality molds, misuse can damage or degrade them. While we can help troubleshoot problems and provide advice, we do not offer returns/exchanges on used items. Please refer to our policy (located at the bottom of our page) for more information! If you see anything out of the norm with your molds upon receiving them, please reach out to us immediately to resolve any issues!
