How to Use Eco Resin: A Beginner’s Step-by-Step Guide

Eco resin has quickly become one of the most popular materials for handmade décor and craft businesses. Its smooth stone-like finish, low odour, and water-based formula make it ideal for creating trays, coasters, planters, candle jars, and decorative pieces.

If you’re new to eco resin, this guide will walk you through the entire process on how to use eco resin — from mixing to demoulding—so you can start creating confidently.

What Is Eco Resin?

Eco resin is a water-based acrylic casting material used to create decorative objects with a smooth stone or ceramic-like finish.

Unlike traditional epoxy resin, eco resin:

• Contains no harsh fumes

• Is VOC-free

• Uses a simple powder + water mix

• Works well for indoor crafting

This makes it especially popular among home creators and small handmade businesses.

Tools and Materials You Need

Before starting your first eco resin project, gather the following:

• Eco resin powder

• Water

• Silicone moulds

• Measuring cup

• Mixing bowl

• Silicone spatula

• Pigments (optional)

• Acrylic sealer (for protection)

Using good quality materials ensures smoother casting and better durability.

Step 1: Measure the Eco Resin

Eco resin typically follows a 3:1 mixing ratio.

This means:

3 parts powder + 1 part water

Accurate measurement is important because incorrect ratios can lead to:

• Weak casts

• Air bubbles

• Improper curing

Use a digital scale or measuring cups for best results.

Step 2: Mix the Resin

Add water into the mixing container first, then gradually add the eco resin powder.

Stir continuously for about 2–3 minutes until the mixture becomes smooth and lump-free.

The final consistency should resemble thick cream or pancake batter.

Avoid overmixing, which can introduce air bubbles.

Step 3: Add Pigments (Optional)

If you want coloured pieces, add pigment during the mixing stage.

You can create beautiful effects such as:

• Terrazzo textures

• Marble swirls

• Solid pastel tones

• Minimal neutral designs

Always mix pigments evenly to ensure consistent colour distribution.

Step 4: Pour Into Silicone Moulds

Slowly pour the mixture into your silicone mould.

Tap the mould lightly on the table to release trapped air bubbles.

Eco resin works best with silicone moulds designed for decorative casting, such as trays, coasters, or planter moulds.

Step 5: Let It Set

Eco resin begins to harden fairly quickly.

Typical setting time:

30–45 minutes

Once the material feels solid, gently remove it from the mould.

Handle the piece carefully, as it will continue curing after demoulding.

Step 6: Allow Full Curing

Although eco resin demoulds quickly, full strength develops over time.

Complete curing usually takes:

24–72 hours

During this period, avoid exposing the piece to heavy moisture or pressure.

Step 7: Seal the Surface

Eco resin is naturally water-resistant but slightly porous.

To protect your pieces, apply a clear acrylic sealer once the piece has fully cured.

Sealing helps:

• Prevent stains

• Improve durability

• Add gloss or matte finish

• Protect against moisture

This step is especially important for coasters, trays, and planters.

Common Beginner Mistakes to Avoid

Many beginners face similar issues when starting with eco resin.

Here are some common mistakes:

Incorrect mixing ratio

Always follow the recommended powder-to-water ratio.

Overmixing

Too much stirring introduces bubbles.

Demoulding too early

Allow enough time for the material to set.

Skipping sealing

Sealing improves durability and appearance.

Avoiding these mistakes will significantly improve your final results.
