If you are wondering how to epoxy resin a tumbler, you are in the right place! Applying a coat of epoxy resin to a tumbler is a great way to personalize or seal your artwork. Here are the steps to epoxy a tumbler.
Choose a tumbler
Stainless steel tumblers work best. Resin likes to stick to metal, so you don’t have to worry about your resin peeling off the surface. The stainless steel is also firm, meaning you don’t have to worry about your tumbler shrinking and expanding which can also cause your resin to crack and strip off the surface.
Clean your tumbler
In order for the resin to stick to your tumbler, the surface must be clean and free of any dirt, especially greases, and oils. Isopropyl alcohol works great for this.
Decorate your tumbler
If you want to let the resin do the work, you can do that too. Skip this step and instead add glitter or colors to the resin and apply once your tumbler is turning.
Set up your tumbler turner
Because resin wants to lie on a flat surface, and a tumbler has a curved surface, you have to keep your tumbler moving while the resin is wet. If you don’t, your resin will run off the side or pool in places and not coat evenly. The easiest way to keep your resin moving is to use a turner, similar to a ‘rotisserie cooker’ to keep your cup moving. Your cup will need to turn while you apply the resin and during the entire resin curing time. There are ready-made and DIY options for creating a resin tumbler turner.
Protect areas where you don’t want resin
Because resin is fluid and will want to go everywhere with this project, you need to tape off areas that you don’t want to get resin. Use painter’s tape to cover openings and other places you don’t want resin to cover.
Prepare your work areas
Because resin is going to drip onto your work surface, you want to be sure you have your table protected. A garbage bag, plastic painter’s tarp or something similar works great.
Mix your resin
Once your area is set up, mix your resin. In my experience, an average size tumbler takes 1/2 ounce of resin to cover it with a light coat. You might want to mix more than that and have a couple of extra projects ready to go just in case you have leftover resin. Here are a few of my favorite leftover resin projects.
By the way, if you have never mixed resin before, there are a few details you want to be sure to get right. Here’s how to mix resin and hardener in five easy steps.
Apply the resin
You may be wondering exactly how to epoxy resin a tumbler. Don’t be afraid, it’s actually pretty easy. Use your stir stix or a foam brush to apply the resin or directly pour the resin on the tumbler. If you are wearing safety gloves, you can also use your hands to apply the resin. You want to be sure you are using a resin designed to coat tumblers, so that it covers evenly and without fish eyes and voids.
Let the resin cure
Keep the tumbler turning until it is fully cured. This depends on the resin you use but usually takes 18 to 24 hours.
Enjoy your beautiful epoxy resin tumbler project!
