What You Need Before Making Resin Molds
Before you jump in, gather your supplies. Here’s what you’ll need:
Resin: Epoxy resin is the most common for crafts. It’s clear, strong, and easy to use.
Mold Material: Silicone is the best for most projects, but you can also use plastic, tape, or even household containers. Always check the type of plastic—some, like polystyrene, may bond with resin, so test a small amount or use a release agent.
Mixing Tools: Plastic cups, wooden sticks, and measuring spoons.
Safety Gear: Gloves, apron, and a well-ventilated workspace. For larger projects or enclosed areas, consider using a respirator mask.
Release Agent (optional): Helps get your finished piece out of the mold easily, especially when using non-silicone molds.
💡Pro Tip: Always read the instructions on your resin and mold material before starting.
Choosing the Right Material for Your Resin Mold
Not all molds are created equal! Here’s a quick look at your options:
- Silicone Molds: Flexible, reusable, and perfect for resin. They capture details really well.
- Plastic Containers: Great for simple shapes, but always check the type of plastic. Some plastics, like polypropylene and polyethylene, are non-stick, but others (like polystyrene) can bond with resin. Testing or using a release agent is a smart move.
- Household Items: Try Tupperware, plastic cups, or even food containers for budget-friendly molds, but always do a small test first.
- Homemade Barriers: Tape, clay, or hot glue can help you build custom shapes.

Step-by-Step: How to Make Silicone Resin Molds
Want to make your own silicone mold for resin? Here’s how:
1. Prep Your Workspace and Object
Cover your work area with plastic. Choose the item you want to copy—like a figurine, pendant, or even a key.
2. Mix Your Silicone
Most silicone mold kits come with two parts. Mix them together as the package says. Stir slowly to avoid bubbles.
3. Build a Mold Box
If your item is small, use a plastic cup or food container. For bigger items, make a box using cardboard and tape.
4. Place Your Item
Stick your object to the bottom with a little glue or clay so it doesn’t float.
5. Pour the Silicone
Slowly pour the silicone over your item. Tap the sides to help bubbles rise and pop.
6. Let It Cure
Wait the recommended time—usually a few hours. Don’t rush it!
7. Remove and Clean
Gently peel away the mold. Wash it with soap and water before using.

How to Use Household Items as Resin Molds
Plastic Cups: Great for small projects. Just pour in the resin and let it cure. Always check the type of plastic first, and consider testing with a small amount of resin to make sure it won’t bond.
Food Containers: Line with tape if you’re worried about sticking, and test first if you’re not sure about the plastic type.
Tape and Clay: Build walls on a flat surface to create custom shapes.
💡Quick Tips:
✅ Resin won’t stick to most plastics like polypropylene or silicone.
✅ If using glass or metal, always use a release spray or line with plastic wrap to prevent sticking.
✅ If you’re unsure about the plastic, do a small test pour first or use a release agent.

How to Use Your Resin Molds
Now that you have your mold, it’s time to pour resin!
1. Mix Your Resin
Follow the instructions for your resin. Usually, it’s equal parts resin and hardener.
2. Add Color or Embeds
Mix in glitter, dried flowers, or color powders if you want.
3. Pour Slowly
Pour resin into your mold in a thin stream to avoid bubbles.
4. Remove Bubbles
Use a heat gun or blow on the surface to pop bubbles.
5. Let It Cure
Leave your piece undisturbed for the recommended time—usually 24 hours.
6. Demold Carefully
Gently peel the mold away. If it’s sticky, let it cure longer.
7. Clean and Store
Wash molds with soap and water. Store flat to keep their shape.
Troubleshooting Resin Mold Problems
Even pros run into issues! Here’s how to fix common problems:
Cloudy or Sticky Resin: Usually means it wasn’t mixed well, the room was too cold, or you used too much colorant.
Bubbles: Mix slowly, pour in thin layers, and use a heat gun to pop them.
Resin Stuck in Mold: Use a release agent next time, or put the mold in the freezer for a few minutes before trying again.
Uneven Surfaces: Make sure your work surface is level.
If your mold is damaged or torn, you may need to make a new one. Silicone molds usually last for many uses if you care for them.
