DIY Resin coasters

Have you ever worked with casting resin before? If you don’t know how to use resin, these DIY resin coasters are going to be a great place for your crafting journey to begin. I’m excited to share with you everything I know about making Mod Podge resin coasters. You are in for such a treat!

Resin coasters are perfect for home decor or gifts. And while resin dries clear, you might notice that these coasters are not. That’s because I’m going to show you some different examples with additives you can use to personalize them! Once you get started with resin, you’ll never want to stop making. Trust me.

Making Resin Coasters

Before we get into the projects, I wanted to share some things you should read about making these coasters if this is your first time. Generally speaking, this is the four step process that you’ll go through to make them.

  1. Prepare Your Supplies – this includes any taping if necessary, laying out everything you need, and organizing your protective equipment.
  2. Mix the Resin – always observe packaging instructions and mixing amounts (which are usually 1:1). You may want to mix in things like glitter, alcohol inks, and paint at this time.
  3. Pour the Resin – pour the resin into the molds. For things like dried flowers and other larger objects that you want to place into your coasters, do that at this time.
  4. Remove Bubbles – let the coasters sit for a few minutes, then remove bubbles by blowing through a straw, exhaling on the surface, or using a torch.

Once you’re done with these steps, you’ll let the project set for 24 hours and then de-mold. It’s that easy!

How do I mix the resin?

Always read and follow the instructions of your specific resin. Having said that, (generally speaking) this is the process.

To mix resin, begin by measuring out equal amounts of resin and hardener – (measure by volume not weight). Use a separate measuring cup for each part. Once equal amounts of both parts are measured, pour them into a mixing cup. Gently stir the two parts together for 3 minutes. When you start to stir, cloudy swirls will appear.

While mixing, make sure to scrape the sides and bottom of the mixing cup to fully incorporate the two parts. Continue to mix until the cloudy swirls no longer appear and the mixture is clear. NOTE: it is best to only mix the amount that will be needed for each project, one project at a time.

How long after mixing the resin will it then begin to harden?

Mod Podge Resin has a working time of 20 – 30 minutes. During this time, you can mix in additives such as alcohol inks or glitters.

How can I thin out the resin mixture?

Place both parts into a warm water bath of 80°F, but be aware that the working time will be less than 20 – 30 minutes.

How long does it take resin coasters to cure?

Your coasters will begin drying within the first 24 hours. However, a resin project will be fully cured after 7 days.

How should I prepare my work space?

When working with resin, it is best to work in a room that is well ventilated with fresh air and work in temperate 70°F.  Make sure your work table is level and is covered with wax paper or a large plastic sheet. This will make it easier to wipe away resin and hardener spills.

Note: Mixed resin spills, once cured, will peel off the wax or plastic covered work surface easily. Gather all the necessary supplies such as: paper towels, plastic measuring cups, plastic mixing cups, plastic or wooden mixing stick, disposable brush, toothpicks, and a butane torch. And always wear your personal protective equipment.

Supplies You’ll Need

  • Clear epoxy casting resin, like Mod Podge Resin
  • Silicone coaster mold(s)
  • Glitter (or other mix ins)
  • Cups for pouring and cups for mixing (if they don’t come with your kit)
  • Craft sticks or other stir sticks
  • Gloves
  • Respirator
  • Timer
  • Butane torch for popping bubbles
  • Drop cloth (or something else to protect your surface)
  • Clear bumper feet

Each coaster mold takes about 2 oz. of epoxy casting resin. Keep that in mind depending on how many molds you have and how many coasters you would like to produce.

Mix the Epoxy Resin

If you have four coaster molds, you can mix all 8 oz. of resin. If you only have one mold, you can use a UV dryer to speed up drying or do the project over four days.

For one resin coaster, mix 2 oz. of product in a 1:1 ratio of hardener and resin. Split evenly into three cups. In one cup, add a pinch of a blue glitter, in the second, add a pinch of a different blue glitter, in the third, a pinch of another blue glitter. Stir each cup slowly until glitter is combined with the epoxy resin.

Pour the Resin into the Mold

Pour each resin mixture into the coaster mold slowly, in a swirling motion, only pouring a little of each color at a time. Layer the colors and use a craft stick to gently swirl the colors together. Let set for two minutes.

Remove the Bubbles

Remove any bubbles carefully using a butane torch. Alternatively, you can exhale on the epoxy resin or blow through a straw. Leave for five more minutes, see if any additional bubbles appear, and repeat.

Remove Your DIY Resin Coasters from the Mold

Let dry for 24 hours and remove your coaster from the mold. They will be fully cured in 7 days. At this time you can add clear bumper feet to them if you like.

There’s a video that illustrates the very simple process below:

Galaxy Coasters

These resin coasters use purple, blue, magenta, and black glitter. Mix 4 oz. of resin according to instructions. Add a a pinch of purple, blue, and magenta glitter to the resin. Pour approximately 1 oz. or 1/4th of the resin into each mold. Use the torch to remove bubbles and let set an hour. Mix the remaining 4 oz. of resin. Add the purple, blue, and magenta glitters again – and this time add black. Pour the mixture to fill each mold and remove bubbles.

Rainbow Coasters

Rainbow resin coasters

You’re going to need six acrylic paint colors and multiple cups to mix. Mix resin according to instructions on packaging. Mix 2 drops of each paint color with resin in their individual cups. Allow the colored resins to sit for 25 minutes. Pour into the mold in rainbow order as shown above. Remove bubbles and let set for 24 hours.
