Step-by-Step Guide: How to Add Pigments & Powders to Resin, Paint & Clay

Mixing pigments and powders into resin, paint or clay can feel intimidating for many artists not just in Pakistan, but everywhere. Yet used correctly, they open up incredible possibilities: vibrant hues, metallic shimmer, smooth blends and professional-grade finishes. At Fine Art Supplies we’ve seen countless customers overcome the frustration of muddy colours, uneven textures or cracked finishes simply by mastering a few key techniques. This guide walks you through the full process so you’ll know exactly how to add serious pigment power to any medium, including practical tips for the best results.

Why Use Dry Pigments & Powdered Colourants?

Many artists struggle with issues like:

• Thin, watery colour that bleeds or lacks depth
• Inconsistent finishes when switching between resin, paint or clay
• Colours that fade, shift or become dull over time

Dry pigments and powders give you precise control; they're highly concentrated, stable, and versatile across mediums. According to years of resin-art guidance, “pigment powder is an easy way to add colour and vibrancy… it affects depth of colour and vibrancy when added in larger quantities.” 

Whether you’re working with epoxy resin, acrylic or gouache paint, or polymer clay this guide ensures you won’t waste materials or end up with unpredictable results.

Step 1: Gather Your Materials & Prepare Your Workspace

• Choose your base medium: resin, paint or clay.
• Grab a reliable pigment: for example, the product “ST Gouache Powder – Basic Colours” (link to product) or “ST Gouache Powder – Fluorescent Colours” (link).
• For metallic or shimmering effects, consider the “Metallic Pigments Pack of 6” (link).
• Use appropriate tools: mixing cups, stirring sticks, gloves and dust mask (powder means particles).
• Work in a well-ventilated area and protect surfaces especially important for resin.

Tip: It’s smart to keep a “clean medium” test cup on hand—mix your base without pigment first, then use a second cup for pigment mixing. That way you measure effect and behaviour safely.

Step 2: Measure & Add Pigment Correctly

When working with powders, measure carefully. Too little pigment may yield a faint effect; too much can cause cracking, curing issues (in resin) or muddy paint mixes. For instance:

• For resin: After mixing resin and hardener, add pigment powder slowly. Stir gently to avoid air bubbles.
• For paint: Take a palette or mixing container, add pigment powder to your paint base (e.g., acrylic, gouache or clay slip) and blend thoroughly.
• For clay: Knead powdered pigment into the clay until colour is uniformly distributed, then proceed as normal.
  

For example, the ST Gouache Powder in Basic Colours is ideal when you want clean, strong non-fluorescent tones without shifting colour when mixed. And the ST Fluorescent Colours version is perfect if you aim for bold, modern highlights.

Step 3: Mix & Disperse the Pigment

Proper dispersion is key. If pigment particles remain clumped, you’ll see specks or uneven tone. Here’s how:

• For resin: Use a stir stick and scrape sides and bottom. After mixing, pause and allow bubbles to rise.
• For paint: You may use a glass muller or palette knife to work the pigment into the base until smooth.
• For clay: Fold and knead thoroughly. If the pigment shows streaks, continue kneading until fully blended.

Remember: powders behave differently from liquid dyes—they may settle, shift or alter texture if not properly mixed. 

Step 4: Test & Adjust Your Colour

Before you commit to a full piece:

• Apply a small sample of your mixture to scrap material or mold.
• Check colour, opacity, and texture after curing or drying.
• If colour is too faint, add a tiny extra pigment. If it’s too thick, dilute with base.
• For metallic powders (like the Metallic Pigments Pack of 6), note that shimmer may appear subtle when wet but intensify when dry or cured.

This testing step saves you from costly mistakes. Many artists skip it and end up re-working entire pieces due to unpredictable behaviour.

Step 5: Use With Each Medium (Resin, Paint, Clay)

Resin

After base resin is mixed and pigment added, pour quickly before curing starts. Avoid modifying the mixture once it begins to gel. If you’re layering colours, add each layer as it reaches a tacky state. Metallic powders give gorgeous effects in resin surfaces.

Paint

Use as you would colour in gouache or acrylic: prime your surface, apply mixed paint, let dry. Since many powder pigments are stronger than pre-mixed tube colours, you may need less product for richer tone.

Clay

When mixing pigment into polymer or air-dry clay, knead until uniform colour is achieved. Then sculpt or roll as desired. Powdered pigment offers greater control for subtle pastel tones or deep saturated shades. Many clay artists note that powdered pigments offer more consistent results than liquid colourants.

FAQs

Q1: Can I mix different pigment powders together?

Yes, combining powders like metallic and fluorescent can create custom effects. Just test first to confirm compatibility.

Q2: Will adding too much pigment affect curing in resin?

Yes. Excess pigment can interfere with resin chemistry, causing long cure times or brittle surfaces.

Q3: Do powdered pigments work with any paint binder?

Generally yes, but always test the pigment in your specific paint binder (e.g., gouache, acrylic) to ensure full integration.

Q4: Are all pigment powders safe for clay and resin use?

Not necessarily. Always check pigment quality, particle size and suitability for your medium. Poor-quality powders may affect curing or finish.

Q5: Is there a difference between gouache powder and pigment powder?

Yes. Gouache powder (like ST Gouache Powder) is designed for paint use; pure pigment powders may be more concentrated and suited for multiple mediums.
