Paint your tumbler (if you want to).
Once your tumbler is painted and dry, brush on a nice and even coat of the Glitterific.
After the Glitterific is dry, you can remove the painter's tape and prepare to add your epoxy resin.
Prepare your Spin It by ensuring the nut on the very end is tight. Adjust the turner to make it larger or smaller as needed.
Let's apply the first coat of epoxy. Apply more painter's tape to the top and bottom of your tumbler. Put it a little outside of your glitter line so that the epoxy will lock in all of the glitter.
Put the tumbler on the turner and make sure it fits tightly. Adjust it as needed.
Epoxy will get all over the place, so cover and protect both your work surface and the base of the Spin It before you begin spinning.
Prepare resin according to the package directions.
Turn the Spin It on and start spinning at a low speed. tart pouring the prepared resin onto your tumbler. I used a stir stick to push the resin around to make sure I had complete and even resin coverage. Allow the epoxy tumbler to spin while it cures.
After an hour or two, the epoxy should be set enough that you can remove the tape from the top and bottom.
Once the resin is set, stop spinning. Leave the tumbler on the machine to continue curing overnight.
Spray your epoxy tumbler with water and sand down the entire tumbler, making sure to sand down any imperfections.
Use rubbing alcohol to thoroughly clean the entire surface and dry well before continuing.
Apply transfer tape to add a vinyl design to the outside of your glitter tumbler.
Peel back the backing paper and apply the design to your tumbler with the transfer tape.
Burnish well, then peel back the transfer tape to reveal your design on the tumbler.
Add a second coat to your epoxy tumbler to seal the vinyl and complete the project. Just follow the same process you used to add the first coat.
