How to Make Molds for Resin
It wasn’t all that long ago that I tried my hand at making a custom mold for clay. It was such a success that I decided to go even further. Could I make a good mold for resin? And when I found a rose cabochon that I could buy one of when I wanted 6 it seemed like a good enough time to give it a go.
The answer is YES you CAN make molds for resin. In fact, the result was far more impressive than I had even dreamed it could be. Granted I experienced some issues but rest assured, making fabulous molds for your resin projects is very easy and with this tutorial you’ll soon be on your way!
Since I’m hardly chatty today, let’s just dive right in, shall we?
For this project you will need:
- Easy Cast Resin (not what I used here but definitely my preferred brand)
- Amazing Mold Putty
- original item to replicate
- razor blade
- timer (on a phone works well)
I’m going to let you in on a little secret from the get go. Take a peek at the number on the phone timer throughout the tutorial. Totally forgot to start the darn thing which did me absolutely no good. So don’t just set the timer, actually hit start!
Also going to let you in on a little something before you begin that I didn’t consider. When choosing your item to replicate be sure that it is something that can easily come out of the mold. Additionally, check and see if there are two or more pieces glued together to make the one thing. For example, the last round of petals on my rose snapped right on off. If I had made a mold for the top portion and then the bottom portion separately the whole thing would have been far more successful. As it was I made the mold for the entire rose without even thinking to check. So separate out any pieces that you can without completely destroying the item.
Take equal parts white stuff and yellow stuff from the tubes. Mix it together very well.
Roll the clay into a ball and start to flatten out. Mold around your item, pushing into air pockets and folds as needed to get an exact duplicate.
Feel free to wrap the mold maker around the back side if it makes things easier to get all of the detail you need. Allow the mold to sit for about an hour to harden.
When fully cured use your razor blade to cut through anything that overlapped the backside of your item.
Carefully remove the original and you’ve got your mold. Doesn’t that look fantastic! You can totally tell it’s for a rose :)
Fill with resin following the package directions. Allow to set per directions as well. Mine took almost 2 days before the backside was no longer sticky and could be removed.
Now you can see just where my problem with the back part not being detached came in. These roses were obviously made in two parts for a reason. In order to use this rose I had to pull the mold out between the last and next to last set of petals. It was a pain in the ASS!
It also messed up the mold. Double dang.
But once I spray painted my rose to get a better idea of how it turned out (the clear resin was just so… clear) and I was pretty darn stoked. The top portion is practically perfect. The back round of petals… meh. But I totally know how to do it better now. And guess what?! I’ll be having my six roses in no time at all!
One thing to note, the end result isn’t perfectly clear, it’s actually rather cloudy. With a bit of sanding (if it were a more smooth item than this) might be able to clear it up a bit, though!
