How to Make Epoxy Resin Coasters (Step by Step DIY Guide)

Making colorful craft resin coasters is fun!

While some of you might be a fan of making geode resin coasters or, agate arts with glitters, some others like to play around with dried pressed flowers, leaves, petals, and other sorts of creative craft ideas.

Whatever the idea you have in mind, just ensure you pick the best resin for coasters. You might be able to create coasters using some ordinary resins, but when it comes to durability and heat resistance, they’ll just fail!

With that in mind, let’s see how is epoxy resin used for coaster making? And, this will be a complete guide, very much helpful, especially for those DIY beginners!

Steps of Making Resin Coasters

Based on the type of resin you’ve chosen, you’ll get a certain amount of work time once you mix them. Otherwise, it will get hardened up. So, make sure you’ve gathered all the essential materials before you even start –

Materials you’ll need:

Step 1: Shape Your Idea in Mind

This is the very first and important step that most people would avoid carelessly. And, that is to define the creative idea in your mind first. That’s because based on your design the process might be slightly different.

Step 2: Measure Resin and Hardener

Measure Resin and Hardener

Based on the size and type of your coasters, measure the right equal amount of resin and hardener by volume. So, how much resin do I need for a coaster? Well, just for an idea, you’ll need approximately 3-4 ounces of epoxy resin to create one coaster. You’ll have to take resin in one cup and hardener into another by 1:1 proportion.

Step 3: Mix Them Well

Now, pour one into the other and mix them very well with the mixing sticks. Mix it carefully for about 3 minutes and try not to produce bubbles as much as possible. Although a high-quality resin will have degassing property that releases bubbles. You’ll have to scrape the sides and bottom of the cup very well. That’ll ensure there’s no stuck portion of resin and hardener is left. To create multiple layers of color effects, take the resin in different cups to add each of your expected colors.

Important Tip:

  • Ensure a well-ventilated workplace for safety practice
  • Put on hand gloves for safety

Step 4: Adding Color to Epoxy Resin

Adding Color to Epoxy Resin

You can just add your favorite color to the mixture. If you’ve planned to use glitter, make sure you add them into the cup as well. For any sort of color experience, you’ll have to use the clear casting resin. On the other hand, to create galaxy resin coasters with a beautiful geode or agate abstract look, use black resin. Some of the most common colors that you can play around with are –

  1. Acrylic Pigment Color Inks
  2. Acrylic Paint Color
  3. Best Mica Powder for Resin
  4. Best Alcohol Ink For Resin

Step 5: Pour into the Mold

Hopefully, you’ve already planned how you’d like to decorate and shape your idea into the mold. Make sure that the coaster mold is clean and free from any kind of fingerprints or anything. Now, pour the resin inside the mold like a ring shape or, you might start by first pouring onto the center.

Starting by the center is the easiest way to apply most of the crafting effects like geode textures. Because then, the resin will spread around to the mold edge. The self-leveling property helps it to level properly. If not, you might use a craft spatula to spread the first coat.

Important Tip:

  • Use a heat gun if necessary to eliminate bubbles
  • You can always use an art resin torch for the same purpose
  • Don’t overhead the surface, just do what you need

Step 6: Let it Cure

Now, cover your coasters with a clean cloth or something to prevent external dust and keep them in a safe place. You should allow about 24 hours (or more depending on the situation) to let it dry fully before you unmold it. Molds that are made with silicone won’t be sticky to the resin. Also, you might use a resin mold release product to extend its longevity.

Step 7: Polish Your Coasters

The final step! Cured resin will come out rock-solid and sturdy with a neat surface finish. But, in case if you need it, you might use fine-grit sandpaper or a high-quality resin polish. That way, you can achieve a better finish and excellent outlook. Hence you might use a sanding block as you’ll just be holding the coaster in hand.
