Introduction: Epoxy As a Sealant
Today, I'm going to go over how to quickly and cheaply seal, protect, and perhaps pretty up your finished polymer clay creations, using epoxy.
Usually, when talking about epoxy & crafts, people imagine epoxy resin that you create molds with etc. However, that type of epoxy can tend to be rather pricey, especially after shipping, if you get it online. And if you live in a small town or rural area as I do, the options for good crafting supplies are very limited, and/or over an hour drive away... with completed projects stacking up, I found an alternative you could use in a pinch.
Small plastic container
Popsicle sticks or paintbrush
Gorilla, JB Weld or similar, clear epoxy
Step 1: Prep
Lay down some wax paper over work area. And gather items you wish to treat, and other supplies. You will have to work quickly with this stuff, as it sets in 5 mins. Once that happens, you will no longer be able to apply it to your piece. So preparation is essential.
Step 2: Mixing Epoxy
This part is simple. The epoxy comes in a syringe so you wont have to measure out anything.
Take your plastic container and epoxy, evenly press the plunger of epoxy to dispense desired amount into container. This will vary depending on the size of your piece. Mix thoroughly for 10 seconds or so. *note* this method is best for very small things only. The set time/amount of epoxy doesn't allow for large pieces.
Step 3: Coat Your Piece
Working VERY quickly, use stick or paintbrush to cover your sculpture with a thin, even layer of epoxy. Sometimes gravity will settle the epoxy and leave spots without it. Seen in the photos above. Dont worry about this too much. Just mix a little more epoxy and fill any gaps, making sure to smooth it flush with the rest.
If you decide to use a paintbrush, choose one you dont mind throwing away or be advised, you will need to work even quicker & have a bowl of acetone or rubbing alcohol with 1/2 tsp dish soap in it ready to put brush into. This will halt the setting/curing process of the epoxy and clean your brush.
Step 4: Finishing
Allow epoxy to dry overnight or until it is no longer sticky/tacky to touch.
**For trinket bowls like the ones I've done here. I recommend allowing it to dry upside down. In my experience, the epoxy seems to dry more evenly this way and doesn't "pool" up at the bottom of your dish or around the outside. Any excess will be at the top of your dish. Then after curing, you can just sand it down a bit and if neccessary use clear nail polish or a tiny bit more epoxy to remove blemishes.
