Choose a Quality Resin Top Coat: Use a clear epoxy resin designed for surface coatings, such as Art Pro , which offers outstanding clarity and protection. Mix and Apply Carefully: Prepare your resin following the manufacturer’s ratio for best results. Pour or brush a thin, even layer over the cured, coloured piece on a dust-free surface. Remove Bubbles: After pouring, use a heat gun or torch briefly to dispel surface bubbles and ensure a flawless finish.

Seal Your Resin Surface to Protect the Colour

When you’ve created a piece with rich, eye-catching colours in resin—whether from eyeshadows, powder pigments, or liquid colourants—sealing the surface gives your creation lasting vibrancy and a polished look. This guide explores why sealing matters and how to do it for best results.

Why Seal Your Resin Surface?

Sealing your resin project acts as a protective barrier over decorative layers. Without a clear coat, surface pigments or mica may wear away or lose intensity from handling and exposure. A proper seal helps maintain the boldness and sparkle of your chosen colours, enhances the finish’s depth, and makes cleaning easier.

When This Matters Most

Sealing is especially important for pieces subject to frequent handling, such as jewellery, coasters, or tabletops. If your design includes lightweight powders like eyeshadow, a durable clear coat prevents smudging and maintains a smooth, high-gloss surface.
