How to Use Resin Molds for Beginners

Resin mold is a great place to start your DIY projects! They're fun, easy, and you can make great gifts and trinkets with them. However, do you know how to work with them as a resin beginner? This article will walk you through everything you need to know about your silicone resin molds.

What You'll Need

  • Molds
  • Epoxy Resin
  • Mixing Cups
  • Popsicle stick
  • Personal Protective Equipment(Goggles, Gloves, Mask/Respirator)

5 Simple Steps



The silicon molds can easily get dirty like dust and other particles, which can totally ruin your resin projects once it cures. So, you'd rather wash it thoroughly before you use (tape is also a great option). FYI, baby wipes is a game-changer!
Gently wash with hands, being careful not to scratch the surface of your molds, and then set face down on a towel to dry. Pat gently with a second towel and you're ready to use!



Before working with epoxy resin, make sure to wear your protective equipment and work in a well-ventilated area because resin is toxic even if it's No VOCs or FDA approved. Now measure out the amount that you need, and make sure it's EXACT. The mixing stage is where most people go wrong. While you're mixing, it's really crucial that you continuously scrape the outsides of the cup to make sure that you're thoroughly mixing. Also, take your time when mixing because mixing too fast will cause so many bubbles during curing. 

QUICK TIP: Store and mix your resin in a room between 70-75℉ (20-24℃).



When pouring your resin, it's important that you get it into the corners of the mold first to ensure that there won't be any trapped air bubbles. If you're making something that is deeper than normal and actually you don't have deep casting resin, then you can pour in different layers. In order to avoid getting and seeing all those separate layers, the subsequent pour must be applied before that previous layer is fully cured(Kind of like in that firm gel state).



Pop it out carefully (Do not pull it if your resin stuck because you will rip your mold). Casting from long and skinny molds can be hard to get out, try to use the mold release agent like detergent, cooking oil and etc. If you don't have the release agent, simply soak the mold into some hot water, which can effectively soften up the mold and resin.

TIP: Do not use sharp tools to peel them out in case the mold gets ruined.



Clean your molds with warm water and mild soap before storing it. Let it dry and it can be directly used to make the next project! If your resin is sticky and can't be demolded directly, then these clean-up tricks are a go-to read for you.

TIP: remember to wear the gloves to clean your molds.
