How to make your perfect dried flower coaster

Here's a picture of a beautiful coaster that has coasters made of epoxy resin.

Additional materials:

  • dried flowers and hay
  • mold


Product Introduction

1.What is It
BOND CRAFTOR Epoxy Resin is an environmentally friendly system that cures effectively at room or low temperatures. Engineered for exceptional clarity and self-debubbling properties, it offers triple the yellowing resistance of conventional resins. With a smooth-flowing viscosity of 2,000±300 mPa·s when mixed, it forms a glass-like, high-gloss finish. Its user-friendly 1:1 volume mix ratio (1.2:1 by weight) and manageable 25-minute working time make it ideal for both beginners and professionals. Once cured, it achieves a durable Shore D 82 hardness and withstands temperatures up to 90°C.

 

2.How to Use
Perfect for tabletops, coasters, tumblers, and electronic encapsulation, this resin is simple to apply. Begin by thoroughly cleaning containers and pre-warming Component A to 30°C if the ambient temperature drops below 15°C. Precisely measure Components A and B by weight, then stir the mixture clockwise along the container walls. After resting for 3-5 minutes, pour at a coverage rate of 280-350g/m²—its self-leveling nature ensures a ripple-free surface. Initial curing occurs in 5-6 hours at room temperature, with full cure achieved within 36-48 hours. For environments with humidity exceeding 85%, heated curing is recommended to prevent surface hazing. Custom coloring is easily achieved using liquid or powder pigments.

 

3.Operation Cautions
Work efficiently within the 25-minute pot life per 100g batch, and avoid operating in high-humidity conditions (>85% RH) to prevent "blushing" (surface cloudiness). Temperature control is critical: use between 10°C–90°C and store sealed at 15°C–25°C—never freeze or expose to temperatures above 50°C. Note that Component B is moisture-sensitive and must be tightly sealed; use within 6 months for optimal performance. Always wear protective gloves and clean spills immediately.


How to make

 

Step 1: Strict 1:1 Volume Measurement
▼ Core Operation
Measure equal volumes of Component A (resin) and Component B (hardener) using graduated cups. Example: 50ml A + 50ml B.
Weight ratio is 1.2:1 (60g A : 50g B), but volume is absolute 1:1.

This picture shows that when using epoxy resin, the ratio of the main agent to the hardener should be 1:1.

 

Step 2: Pour B into A
Slowly pour Component B into Component A's container. Reverse order causes uneven mixing!

This picture shows how the epoxy resin should be slowly stirred along the clockwise direction with a wooden stirring rod after the resin has been dosed 1:1.

 

Step 3: Mix 3+2 Minutes
Stir clockwise 3 min → Scrape walls → Stir 2 min until zero translucent strands.

 

Step 4: Rest 4 Min for Debubbling
Let sit untouched. Bubbles self-collapse due to 2,000mPa·s viscosity.

 

Step 5: First Pour (2mm)
Pour layer ≈140g/m²

Step 6: Arrange Absolute-Dry Botanicals
Place flowers baked at 60°C for 2hrs. Moisture >0.1% causes blushing.

Step 7: Position Adjustment
If you are unsatisfied with the positions of dried flowers and dried grass, you can adjust them with tweezers.  Complete within 10min (before viscosity rises).

Adjust the order of dried flowers and hay in the epoxy mold to make it more aesthetically pleasing.

 

Step 8: Pour Second Layer

→ Key Action
Pour mixed resin (1:1 volume) to fully submerge botanicals. Maintain ≤10mm total thickness.

Step 9: Cure 24h Under Cover
Cover with upside-down box. Humidity <85%!

The picture shows the 24-hour wait after the above steps have been taken.

 

Step10: Apply Second Layer After 24h Cure

→ Critical Timing & Method

  • Verify Initial Cure: Press fingernail gently on surface – no dent & tack-free = ready.
  • Reblend Fresh Resin: ▼ Strict 1:1 volume remeasure (e.g., 30ml A + 30ml B). Never reuse old mixture!
  • Pour with Care: Drizzle resin from 10cm height to minimize bubbles. Fully submerge botanicals with 1mm clearance.
  • Tip: resin self-levels to glass finish!

 

Step 11: Final Cure 48h
Cure at 25°C ±2°C. Below 20°C extends curing time.

 

Step 12: Demold & Finish
Polish edges with ethanol-soaked cloth for optical clarity.

 

Final Step: Your Masterpiece is Ready!
▲ Your coaster is ready!
Crafted with a precise 1:1 volume ratio and layered curing, the translucent dried flowers are now sealed beneath a highly smooth, yellowing-resistant coating. With a Shore D hardness of 82 to resist daily scratches and heat resistance up to 90°C for practical use, this piece — blending beauty and durability — carries your creative touches and reflects exquisite craftsmanship.
