Epoxy resin art has exploded in popularity, and for good reason—it allows you to create glossy, customized creations that are both beautiful and functional. One of the most satisfying projects to try is epoxy resin coasters with embedded objects. Whether you're capturing flowers, glitter, or small mementos, this guide will walk you through every step of the process, from gathering your materials to perfecting the final touches.
What You’ll Need
Before you start crafting, gather these supplies to ensure a smooth process:
-
Epoxy Resin (2-part resin and hardener)
-
Silicone molds made for coasters
-
Embedded objects like dried flowers, glitter, stones, shells, or small keepsakes
-
Mixing cups and stir sticks
-
Heat gun or torch for bubbles
-
Sandpaper for finishing edges
-
Cork or felt for coaster bottoms
-
Gloves and a workspace protected by a plastic mat or paper
Step 1: Preparing Your Embedded Objects
One of the first steps is to prepare your chosen objects for embedding into the resin. Any moisture can disrupt the curing process, so this step is crucial.
-
Flowers
Fresh flowers can cause issues with resin, so consider drying them beforehand in silica gel or pressing them for a flat finish.
-
Stones, Shells, or Keepsakes
Make sure all objects are clean and dry. Wipe them down to remove dust, dirt, or oils.
-
Glitter or Pigments
These can be used as fillers or accents. Have them ready to add into layers of resin.
Step 2: Mixing and Pouring Resin
This is where the magic happens! Follow these easy steps to mix and pour resin perfectly:
-
Mix the resin and hardener according to the instructions on the packaging (usually a 1:1 or 2:1 ratio). Slowly stir to minimize bubbles.
-
Once fully mixed, pour a small layer of resin into your silicone molds. Use a heat gun or torch to eliminate any air bubbles.
-
Place your prepared objects onto the surface of the resin, arranging them however you like. If doing multiple layers, pour more resin over the objects carefully and eliminate air bubbles between pours.
Pro Tip: Wear gloves to avoid getting resin on your skin, and work in a well-ventilated area. A respirator is recommended.
Step 3: Curing and Demolding
Curing epoxy resin takes patience. Follow these steps to ensure a smooth and flawless set:
-
Allow the resin to cure according to the manufacturer’s instructions—usually about 24–72 hours. Avoid touching or disturbing the molds during this time to prevent surface imperfections.
-
Once cured, gently remove the coasters from the silicone mold. If the edges feel a bit sharp or uneven, don’t worry—that’s where finishing comes in.
Step 4: Finishing Touches
Your coasters are almost ready! Now, give them a polished finish and prepare them for actual use.
-
Sanding the Edges
If the edges of your coasters are rough or uneven, sand them with fine-grit sandpaper (wet/dry sandpaper works best). Do this carefully to avoid scratching the glossy surface.
-
Adding Cork Backing
To protect your furniture and give your coasters a professional look, attach cork or felt bottoms. You can easily find peel-and-stick cork sheets online, or adhere them using a strong glue.
Get Creative!
Now that you know how to make your own epoxy resin coasters, the creative possibilities are endless. You can experiment with:
-
Layering glitter or pigments for depth.
-
Using themed objects like seashells for summer-inspired coasters.
-
Creating sets with cohesive color schemes or mementos.
Whether you’re keeping them for yourself or gifting them to someone else, homemade resin coasters are not only practical but also works of art.
Happy crafting
