Step 1: Prepare Your Workspace and Materials

Set up your project on a level, dust-free surface covered with protective sheeting. Ensure good ventilation, and wear protective gloves at all times. Unpack all tools and familiarise yourself with the process before you begin, as resin has a finite working window once mixed.

Choose fully dried flowers to avoid trapped moisture.

Moisture from live or inadequately dried blooms can cause cloudiness or even mould inside the finished resin cube, so source professionally dried flowers for best results.

Step 2: Mix and Pour the First Layer of Resin

Mix your resin and hardener as per the product instructions, stirring slowly to minimise bubbles. For cubes thicker than 2 cm, go for “EpoxyTable 5-Five”; for thinner projects, “Trasparente” is ideal. Pour a shallow base layer (about a quarter of the mould depth) and allow it to partially cure to a gel state — this supports your flower during placement.

Avoid pouring thick layers all at once to prevent bubbles.

Pouring in stages helps to trap fewer bubbles and maintain maximum clarity.

Step 3: Position and Embed the Flower

Arrange your chosen dried flower gently onto the partially cured base. Use tweezers if required for careful positioning. Press the flower lightly so it does not float when covered by subsequent resin layers.

Use a reusable silicone cube mould for best results.

Silicone cube moulds like the “Cube Mould” – Square Silicone Mould for Resin make demoulding effortless and ensure crisp, clear cube edges.

Step 4: Pour Remaining Resin in Layers

Mix a fresh batch of resin as instructed, then pour gently over the flower in stages, waiting for each layer to set or become tacky before adding the next. This prevents your flower from shifting and minimises the risk of bubble formation.

Clear resin should be poured in layers for maximum clarity.

Pause briefly after each pour to let bubbles rise, then gently pop them using a toothpick or by exhaling softly over the surface to avoid heat damage.

Step 5: Cure and Unmould Your Resin Cube

Allow the cube to cure fully in accordance with your chosen resin’s product instructions. Don’t rush this stage; curing solidifies clarity and hardness, ensuring longevity and a perfect finish.

Remove bubbles carefully after each pour.

After curing, carefully flex the silicone mould to release the cube. Polish with a soft cloth if needed.

Leave the resin to cure fully before unmoulding.

Tips, Common Mistakes, and Troubleshooting

  • If you see persistent bubbles, mix resin more slowly or at a slightly warmer temperature (but don’t overheat).
  • Pouring too thick can cause overheating or incomplete curing; always check the maximum recommended thickness for your resin.
  • Use only fully dried flowers, as live or damp material can ruin clarity or introduce mould.
  • Avoid moving the mould during curing to ensure the flower stays centred and the surfaces remain perfectly level.

Frequently Asked Questions

What is the best resin for embedding flowers in cubes?

Use a clear, deep pour resin such as EpoxyTable 5-Five for cubes over 2cm. For thinner projects, Trasparente resin works well.

How should I prepare flowers before casting?

Ensure the flowers are thoroughly dried to prevent cloudiness or decay. Moisture inside the resin may cause mould.

How can I prevent bubbles when embedding flowers?

Mix resin slowly, pour in thin layers, and remove bubbles using a toothpick or by exhaling gently over the resin.

Read the full guide

When can I unmould my cured resin cube safely?

Wait for the resin to cure fully as per the manufacturer’s guidance. Unmoulding too soon may damage the finish.

Read the full guide

What type of mould should I use for flower resin cubes?

A silicone cube mould is best for this purpose as it is non-stick, reusable, and provides crisp, clear results.

Why should I pour resin in layers?

Layering helps avoid bubbles, ensures even distribution, and stabilises flowers within the resin for the best clarity.
