How Do I Achieve a Polished Edge on Resin Corners?

Achieving a perfectly polished edge on resin corners is what gives a professional and striking finish to your resin project. With the right approach, you can transform sharp or cloudy corners into smooth, glass-like highlights that elevate your work.

Sanding and Preparing Resin Corners

Once your resin has fully cured, begin by gently sanding the corners. Start with a fine grit sanding pad, such as 1000 grit, and gradually progress up to higher grits (like 2000 or 3000) for a refined surface. Use light, circular motions and take care not to oversand the surrounding resin or underlying material. Patience is key—a multi-stage approach minimises scratches and ensures the surface is ready for polishing.

Applying a Polishing Topcoat

After sanding, clean the corner thoroughly to remove dust. For a truly glass-like finish, apply a clear resin topcoat using a high-quality product such as Art Pro Deluxe. This topcoat will self-level, filling in any microscopic imperfections left by sanding and creating a high-gloss, durable edge. Allow the resin to fully cure before handling or displaying your piece.

When Does a Polished Edge Matter?

Opting for a polished finish is particularly valuable for pieces where corners and edges are visually prominent, such as coasters, serving trays, or resin tabletops. A glass-clear edge not only looks impressive but is also easier to keep clean and enhances the overall quality.
