Supplies needed for resin casting – Beginner supply checklist

resin casting suppliesResin casting is a fun and inexpensive way to make jewelry and crafts but choosing resin supplies can be overwhelming. How do you know exactly what supplies you need for casting with resin? Here are the resin supplies I consider essential and the resin supplies that are optional, but nice to have.

Essential resin casting supplies

1. Casting resin. Of course, you need a casting resin. These resins are intended to be poured into something with ‘sides’ like a mold or bezel. They mix in a thinner viscosity, making it easier to pour large volumes of them into molds without introducing bubbles. Casting resins also release bubbles easier, which is essential if you are casting large volumes or in deep pours. If you don’t know the difference between a casting resin and a doming resin, learn why it’s important to know those details here: Casting resin versus doming resin

Pro tip: A resin is either a casting resin or a doming resin. If a manufacturer tells you that it is suitable for both, it’s not your best choice for casting. If it mixes thick enough to dome, then it oftentimes mixes too thick to use in a mold and get a bubble-free casting.

2. Mixing cups. Getting accurate measurements on your casting resin ensures it will cure properly and mixing cups will help you do that. If you don’t mix the right combination of each together, then the mixture may not cure because enough heat isn’t generated to cause the mixture to solidify. Resin mixing cups have measurement lines allowing you to get precise measurements on your resin and hardener.

3. Stirring Utensils. Plastic stir paddles are a great way to make sure you get your resin thoroughly mixed. Thorough mixing is important to making sure that not only your resin cures, but cures without any sticky spots.

4. Safety equipment such as gloves and safety glasses. Casting resins are chemicals and it is important you protect yourself. At a minimum, you need to wear gloves and safety glasses to protect your hands and eyes from any possible splashes or accidents. We have other resin safety information so you can know how to use resin safely.

5. A level surface for casting. Make sure your work area is not only flat on the surface but is also level when resting on the floor. You don’t want to pour resin into your molds only to find they don’t cure straight because your table wasn’t even.

6. Wax paper, freezer paper or some other protective tarp. When resin casting, it is almost impossible not to have a resin drip or spill somewhere. By using something with a waxy surface to protect your work area, you can let spilled resin on the surface cure, then peel it off once it’s solid. You may even decide to throw it all away and start over since these resin supplies are usually inexpensive.

7. Resin molds or some other vessel to pour resin into. Before mixing and casting your resin, be sure what you are pouring it into is compatible. You don’t want to melt or crack resin molds or a container because it couldn’t handle the heat of mixed resin. If you aren’t sure if you should be using silicone resin molds or plastic resin molds when resin casting, this article will help you decide.

8. Mold release. This helps to release resin castings from your molds. Mold release also prolongs the life of your resin molds.  Twisting and popping can warp your mold or produce micro tears that reduce the life of your mold. Mold release is also good to have in case something goes wrong; it may be the only reason you can demold your resin charms.

9. Bright LED light. A bright light is incredibly helpful for seeing bubbles that are hard to see under ambient light.

10. Resin colorants. Colors designed for resin will produce the most consistent results. Because they are specifically designed to color resin, they should not impact curing nor cast with a color different from what you are expecting.

11. Heat tool. A heat gun is a terrific way to remove bubbles and is much safer than using something with a flame, like a propane or butane torch.

12. A sealant such as clear drying white glue or resin gloss sealer spray.  Anything that changes color when getting wet needs to be sealed before including in resin.

I’m thinking of making a “crater” in a piece of hardwood, placing a stone in the crater, and filling it with resin. I would want to leave the stone and the resin in place. Could I use resin and wood?
