I have really gotten into using silicone molds to make fun resin creations. Did you know that it is actually really easy to add glitter and dye to resin projects? I added green glitter and transparent green dye to these fun cactus casts.
The silicone mold that I used was meant to make popsicles, so I had to close the holes for the popsicles sticks with duct tape. To make sure I could remove my finished resin cacti from the mold easily, I applied two coats of mold release to the mold. Be sure to allow it to fully dry in between coats.
Dyeing resin is super easy. Just follow these steps:
- Gather your supplies: polyester resin and catalyst, a mixing cup and stir stick, transparent green resin dye, and glitter.
- Follow the directions for the correct resin to catalyst ratio for your project. Since my mold was about 1″ deep, I added 4 drops of catalyst per each ounce of resin. I ended up mixing up about 5 ounces of resin with 20 drops of catalyst. I mixed for 60 seconds, making sure to scrape down the sides and bottom of the cup as I mixed.
- Add in a few drops of transparent green resin dye. The more dye you add to the resin, the more it interferes with the cure time, so only use as much as you need.
- Stir well until the resin is an even color.
- Add in green glitter. I like using a variety of shades and sizes of glitter for more interest.
- Stir well until the glitter is evenly spread throughout the resin mixture.
I carefully poured the dyed resin into the prepared mold. It is important that the mold is on a level surface so that the cast stays level. I allowed the resin to cure overnight. Factors including the depth of your mold, the temperature of the air, and what you have embedded in the mold will all affect the resin’s cure time. Adjust the amount of time you let your resin cure accordingly. When you tap on the back of your project with a stir stick, it will make a clicking noise when it is fully cured.
I flipped the silicone mold over to remove the finished resin pieces from the mold. The glitter is suspended inside the resin making the casts sparkle beautifully!
While I loved the look of my finished pieces, I decided they would be even cuter with little faces. I quickly painted faces onto the resin cacti with acrylic paint. This step is completely optional, of course. These cacti would make adorable magnets, paperweights or decor items!
