If you’ve ever wished resin projects would cure faster, this resin art tutorial is for you. In this guide, you’ll learn how to make resin flower coasters using a resin curing machine that shortens curing time from half a day to about four hours.
This project combines pressed flowers, gold flakes, and epoxy resin to create beautiful, durable DIY resin coasters. Perfect for beginners and intermediate crafters alike, this method eliminates long wait times and gives consistent, bubble-free results — an essential time-saver for anyone who loves arts and crafts resin projects.
Materials List
Before you start, gather all your tools and materials for a smooth crafting experience.
- Resin curing machine (available on Amazon or similar sites)
- Art resin (Part A and Part B, 1:1 ratio)
- Coaster molds with raised edges (approx. 100 mL capacity each)
- Dried or pressed flowers (preferably darker colors)
- Gold flakes or metallic leaf
- White resin pigment (optional for opaque backs)
- Mixing cups and stir sticks
- Heat gun (set to low)
- Tweezers (for flower placement)
- Small scissors (for trimming flowers)
- Tray or silicone mat (to hold molds during curing)
- Craft knife
- Ruler
- Glue gun (optional for fixing molds)
- Scissors
- Baby wipes and gloves for cleanup
- Respirator
Step-by-Step Instructions
Step 1: Prepare and Set Up the Machine
Remove the resin curing machine from its box, plug it in, and familiarize yourself with the controls. The model used in this project automatically runs for two hours per cycle — no timer settings required. The machine includes two removable racks that hold your molds securely while curing.
Step 2: Mix the Resin
Combine 50 mL of Part A with 50 mL of Part B for a total of 100 mL. Stir slowly for at least three minutes, scraping the sides and bottom of your cup to ensure a complete mix. Mixing thoroughly prevents sticky or uneven results later.
Step 3: Prepare the Flowers
Inspect your dried flowers and trim any crushed petals with small scissors. Choose medium-to-dark colored blooms for the best contrast. Lighter flowers can appear faded once encased in resin, especially over white or pale backgrounds.
Step 4: Add Gold Flakes and Pour the First Layer
Add gold flakes directly into the mixed resin. Pour the resin halfway into each coaster mold — about 50 mL — to create a base layer. Use tweezers to gently position your flowers and a skewer to remove any trapped air bubbles.
Step 5: Cure the First Layer
Place the tray with molds inside the resin curing machine. Close the lid and press the On button. The default curing time is two hours. Depending on your resin brand and room temperature, the first layer may fully cure in as little as 90 minutes.
Step 6: Add the Second Layer
Mix another small batch of resin — 25 mL Part A and 25 mL Part B — and tint it with a few drops of white pigment. Pour this mixture over the cured layer to create a soft opaque backing. Use a heat gun on low to remove surface bubbles.
Step 7: Final Cure
Return the molds to the curing machine for another two-hour cycle. After the cycle finishes, let the coasters cool for about 30 minutes before demolding. The resin should be firm but slightly flexible at this stage; full hardness develops after 24 hours.
Pro Tips & Crafting Guidelines
- Dark flowers photograph and display better than pale ones when paired with light backgrounds.
- Do not combine white pigment with light flowers — it can wash out their color.
- Always pour resin on a flat surface to avoid uneven thickness.
- Warm resin slightly before mixing to reduce bubbles.
- Clean molds immediately after demolding to maintain clarity for future projects.
- The curing machine is ideal for coasters, jewelry trays, and small molds that require consistent heat.
Troubleshooting
| Problem | Likely Cause | Quick Fix |
|---|---|---|
| Flowers appear faded | White backing layer too opaque | Use clear or lightly tinted resin instead |
| Resin feels sticky | Improper ratio or mixing | Measure 1:1 precisely and stir thoroughly |
| Uneven surface | Mold not level in curing chamber | Adjust rack and re-cure for 30 minutes |
| Air bubbles near flowers | Trapped air during placement | Press flowers flat and use heat gun briefly |
Creative Variations
- Metallic backgrounds: Use silver or bronze flakes instead of gold for a different accent.
- Seasonal coasters: Try autumn leaves, spring blossoms, or holiday glitter.
- Personalized sets: Embed initials, charms, or small photos under the final resin layer.
- Tinted layers: Add mica powder or transparent dye for subtle color effects.
- Textured finishes: Use silicone molds with patterns for unique coaster backs.
Each variation transforms the same DIY resin coaster technique into a fresh, custom project — ideal for gifts, markets, or personal home décor.
Final Results
These epoxy resin coasters cured in under four hours total, thanks to the resin curing machine. The gold flakes shimmer beautifully beneath the glossy finish, while the flowers create an organic, elegant focal point.
Even though lighter petals became less visible over the white base, the experiment proved how effective controlled curing can be. The coasters are sturdy, heat-resistant, and perfectly suited for both handmade décor and everyday use.
Conclusion
Fast-curing technology has changed how crafters approach resin art ideas. Instead of waiting overnight, you can complete a polished set of resin coasters DIY in a single afternoon. Experiment with flower colors, metallics, or tints — and enjoy creating professional-quality results at home.
