DIY Tumbler to Keep Drinks Toasty - Expert Home Improvement Advice by Philip Barron

As the weather gets chillier, we’re breaking out our old thermoses and tumblers. But looking at the same old stainless steel that you use every year is getting old. So if you’re looking for a new DIY and a way to spice up your glass cupboard, this project is for you.

Step One: Supplies and Prep

Stainless steel tumbler (I used a 20oz)
Painters tape
Silicone brushes
Upstart epoxy
Disposable rubber gloves
Small mixing cup
Popsicle stick or other stirrer

Once you have your supplies it’s time to prep your tumbler or mug. First ensure that it’s a clean surface and tape off any areas that you don’t want to get epoxy on.

From there, it’s time to prep your Upstart Epoxy. Make sure you have your measuring cups and gloves ready. You’ll also want to review your epoxy calculator before you pour so you know exactly how much you need.

Step 2: Measure and Mix Resin

Once your area is prepped and epoxy in hand, it’s time to mix and start creating your colors. This step is crucial to getting the perfect pour as well as your ideal color. When it comes to mixing your epoxy read the label closely. Generally, epoxies have an easy 1:1 ratio. From there you’ll want to pour your epoxy into your mixing cups until it is a clear and even consistency.

Next is the fun part, adding in your color. A great tip is to pour a small amount of already mixed epoxy into another cup. This will allow you to test out the different colorings until you find the exact color you’re striving for. Once you’ve got your color, go ahead and add your mica powder to the mixed resin and stir until it’s a smooth consistency.

And remember, different epoxies have different working times so be sure that you’re paying attention to the clock once you create your epoxy mixture.

Step Three: Pour

Now that you have your colors ready it’s time to start pouring. The goal is to pour as closely as you can to the tumbler or mug. The further away your pour, the more air you’re allowing to enter into your epoxy mixture which will cause bubbles down the line.

If any bubbles appear on the surface, gently blow through the straw or use a small kitchen torch to disperse and remove the bubbles from the surface.

Once you’re happy with the look of your tumbler or mug it’s time to let your resin “cure,” meaning harden. To do this, you should leave it in a protected space where no debris will fall onto it and no one will touch it. Keep it safe for at least 24 hours.

Keep in Mind

Epoxy resin is awesome to work with. But lots of research is required to find the best product for your needs. Ensure that you find an epoxy specific to your project, that is made here in the U.S.A., and that it has plenty of positive customer reviews.
