Resin coasters are one of the easiest projects for beginners and one of the most popular products for resin artists.

They're small enough to practise with, but you can experiment with colours, flowers, glitter, pigments and different designs.

For coating-style coaster projects, Fusion Vitro 2:1 is a suitable choice.

Step 1: Gather your materials

You'll need:

  • Fusion Vitro 2:1
  • Coaster mould
  • Digital weighing scale
  • Mixing cups
  • Mixing sticks
  • Resin-compatible pigment or mica powder
  • Gloves
  • Decorative elements if required
  • Heat gun or suitable bubble-removal tool
  • Sandpaper for finishing if required

See What You Need to Start Resin Art in India for a complete materials checklist.

Step 2: Calculate the resin required

Before mixing, calculate how much resin your coaster mould needs.

For example, a set of four coasters may require around 115 g, depending on the mould dimensions and design.

Don't mix more resin than you need.

Use the Fusion Resin Calculator to calculate the required quantity.

Step 3: Measure your resin

Fusion Vitro uses a 2:1 ratio by weight.

For example:

  • 20 g Part A + 10 g Part B = 30 g total
  • 40 g Part A + 20 g Part B = 60 g total
  • 80 g Part A + 40 g Part B = 120 g total

Always calculate according to the exact quantity required for your project.

Step 4: Mix slowly

Mix Part A and Part B thoroughly.

Scrape:

  • Bottom of the cup
  • Sides of the cup
  • Corners of the cup

Mix slowly rather than aggressively to reduce unnecessary air bubbles.

Step 5: Add your colour

You can use:

  • Mica powder
  • Resin pigment
  • White pigment
  • Transparent pigment
  • Pastel colours
  • Metallic effects

For a minimal coaster, try:

White + ivory + beige

For a pastel coaster:

Pink + lavender + white

For an ocean coaster:

Blue + turquoise + white

For a geode coaster:

White + black + metallic accent

Step 6: Pour into the mould

Slowly pour your resin into the coaster mould.

Avoid filling beyond the mould's intended level.

If you're making multiple colours, pour them one at a time to create:

  • Marble effects
  • Swirls
  • Waves
  • Geode patterns
  • Colour blocks
  • Floral designs

Step 7: Remove bubbles

Check the surface after pouring.

Use an appropriate bubble-removal method and avoid excessive heat.

Too much heat in one area can affect the resin and decorative elements.

Step 8: Add decorations

You can add:

  • Dried flowers
  • Gold or silver flakes
  • Mica
  • Glitter
  • Tiny decorative elements
  • Lettering

Make sure any flowers or porous materials are properly prepared before embedding.

Step 9: Let the coaster cure

Leave the mould undisturbed while the resin cures.

Fusion Vitro has a typical cure time of around 18–20 hours, depending on working conditions.

Don't rush the demoulding process.

Step 10: Demould and finish

Once properly cured:

  1. Gently remove the coaster from the mould.
  2. Check the edges.
  3. Sand any sharp or uneven edges if needed.
  4. Clean the surface.
  5. Apply any additional finishing coat if your design requires one.

How much resin do 4 coasters need?

A set of four coasters may require approximately 115 g, depending on mould size and depth.

Always calculate according to your specific mould rather than relying only on a general estimate.

Common resin coaster mistakes

  • Incorrect resin ratio
  • Overfilling the mould
  • Too much pigment
  • Mixing too aggressively
  • Excessive heat
  • Demoulding too early
  • Using dirty or dusty moulds
  • Not checking the coaster edges after demoulding
