Pressed flowers resin coasters are timeless, elegant pieces of handmade décor that blend nature’s beauty with the glossy finish of resin. In this DIY resin coaster tutorial, you’ll learn how to create Blue Pressed Flower Resin Coasters using an efficient resin curing machine for fast and professional results.
This project is perfect for all skill levels — even beginners can achieve a stunning finish by following a few key techniques for mixing, pouring, and curing epoxy resin for coasters. You’ll also learn how to keep delicate pressed flowers from floating, how to add subtle backgrounds, and how to achieve a bubble-free surface that looks store-bought.
Materials List
Gather all your materials before you begin to ensure a smooth, stress-free crafting session.
- Art resin (Part A & Part B, mixed 1:1 ratio)
- Resin curing machine or resin warmer
- Coaster molds (flat or slightly domed, 100 mL capacity each)
- Blue pressed flowers and greenery (dried and flat)
- Gold flakes or fine glitter (optional for decorative backing)
- Mixing cups and stir sticks
- Tweezers (for placing flowers)
- Heat gun (set on low)
- Baby wipes and gloves (for cleanup)
- Small scissors (for trimming flower petals)
- Silicone tray or mat (for easy mold transfer)
- Craft knife
- Ruler
- Glue gun (optional, for mold repair)
- Scissors
- Respirator
Tip: Always work in a well-ventilated area and on a level surface. Resin projects cure best when room temperature is between 72°F and 78°F.
Step-by-Step Instructions
Step 1: Prepare the Workspace
Start with a clean, flat workspace. Place your silicone mat or tray where you’ll be working — this makes it easier to move your molds directly into the curing machine later. Have baby wipes on hand to clean up any spills.
Step 2: Measure and Mix the Resin
Each mold holds approximately 100 mL, so for two coasters, mix 200 mL total — that’s 100 mL of Part A and 100 mL of Part B. Stir slowly for five minutes to reduce air bubbles and ensure the resin is fully blended.
Pro Tip: Warming your resin slightly before mixing helps minimize bubbles and improves clarity.
Step 3: Pour the First Layer
Pour a thin base layer of resin into each mold. This will help anchor your pressed flowers. Use a heat gun on low to eliminate any surface bubbles before placing your floral elements.
Step 4: Arrange the Flowers
Using tweezers, carefully place each pressed flower and leaf into the resin. Handle gently — pressed flowers are delicate and can tear easily. To avoid floating:
- Pour only halfway at first.
- Gently press each flower flat into the resin.
- Wait 5–10 minutes before pouring the next layer to allow them to settle.
Step 5: Cure the First Layer
Place your filled molds onto the tray inside the resin curing machine. Close the lid and press Start. The built-in timer will run for two hours, but you may notice curing completes in as little as 90 minutes.
If your curing machine has multiple levels, note that the bottom rack may cure slightly faster due to higher heat distribution.
Step 6: Add Decorative Backing
Once the first layer is fully cured, mix a smaller batch — about 20–25 mL per coaster — of fresh resin. You can add:
- A few drops of white pigment for a soft opaque backing, or
- Fine glitter for a shimmery finish that highlights the flowers.
Mix thoroughly, then pour the second layer evenly over each coaster. Use the heat gun briefly to remove bubbles and return the molds to the curing machine for another two-hour cycle.
Step 7: Unmold and Finish
After curing, let the coasters cool for 30 minutes before unmolding. The resin will feel firm but may remain slightly pliable for 1–2 days.
Trim any uneven edges with a craft knife or deburring tool once fully hardened.
Curing Time: Total curing time for both layers is approximately 4 hours with the resin machine, compared to 24 hours at room temperature.
Pro Tips & Crafting Guidelines
- Level is everything: Always double-check that your curing machine tray is flat before starting. Uneven molds lead to slanted coasters.
- Color matters: Darker flowers hold their color better in resin. Light petals can appear washed out if paired with opaque or white backings.
- Avoid overmixing: Stir slowly to prevent introducing bubbles that can mar the finish.
- Cure in stages: Layering resin creates depth and keeps delicate florals from floating.
- Storage tip: Keep unused pressed flowers sealed away from moisture and sunlight to preserve their vibrancy.
Troubleshooting
| Issue | Cause | Solution |
|---|---|---|
| Flowers floating to the surface | Poured too much resin at once | Pour halfway, let flowers settle, then add more resin |
| Uneven surface | Mold not level during curing | Use a flat tray or adjust rack placement |
| Faded flower color | White or opaque backing used | Use clear resin or lightly tinted color instead |
| Sticky surface | Incomplete resin ratio | Always mix equal parts A and B and stir thoroughly |
| Bubbles around petals | Air trapped under flowers | Press flowers flat and heat lightly with heat gun |
Creative Variations
- Seasonal Coasters: Swap blue flowers for pink blossoms in spring or red poinsettias for holiday gifts.
- Metallic Accents: Add silver or rose gold flakes for a modern, luxe touch.
- Personalized Designs: Embed initials, small charms, or dried leaves beneath the top layer.
- Tinted Resin: Add a drop of alcohol ink or mica powder to match your room décor.
- Nature-Inspired Sets: Mix different flower types in one mold for a botanical collage effect.
Every variation gives you a fresh take on resin art ideas while showcasing your creativity.
Final Results
These Blue Pressed Flower Resin Coasters turned out beautifully — crystal-clear with vivid blue petals suspended in a glass-like finish. The fine glitter background adds subtle sparkle without overpowering the natural details of the flowers.
Each coaster is heat-resistant, waterproof, and durable enough for everyday use. They make excellent handmade gifts, bridal shower favors, or statement DIY home décor pieces that capture the beauty of preserved nature.
