Why does epoxy resin need to be sanded and polished?

For a perfect surface

After curing, the surface of epoxy resin is not always perfectly smooth. Small irregularities, dust inclusions, scratches, or matte areas can impair the result.

 

Sanding epoxy resin removes imperfections and gradually smooths the surface. The right polish then ensures a glossy, mirror-like finish that beautifully highlights the resin's colors and depth.

 

Whether it's an epoxy resin table, a piece of jewelry or a decorative work of art – with the right grinding and polishing technique you can achieve a high-quality finish.

Grain size

What grain size is needed for epoxy resin?

Choosing the right sandpaper grit for epoxy resin is crucial for a smooth, scratch-free surface. Depending on the condition of the cured resin, you start with a coarser or finer grit and gradually work your way up to a fine finish.

​

Important: Avoid skipping larger grit sizes if possible, to ensure that sanding marks are reliably removed and an optimal base is created for subsequent polishing.

From around P800 grit size upwards, wet sanding is often suitable, provided the abrasive is designed for it. This reduces sanding dust and facilitates a consistent fine finish. The appropriate final grit depends on the polishing compound used.

Sanding and polishing epoxy resin

With the right technique and carefully selected abrasives, you can transform a matte epoxy resin surface into a glossy finish. In four easy steps, we'll show you how to properly sand epoxy resin, prepare it for polishing, and bring it to a high gloss.

Grof schuren

Begin indien nodig met een grovere korrel (P80–P240) om oneffenheden, krassen en overtollige epoxyhars te verwijderen. Zorg voor een gelijkmatige druk en een volledig uitgehard oppervlak.

Fijn schuren

Werk stapsgewijs van P320 via P600 en P1000 naar P4000 of P10000. Afhankelijk van het schuurmateriaal kun je tijdens het fijn schuren nat schuren. Verwijder tussen de verschillende korrelgroottes grondig alle schuurresten.

Tips

Common mistakes when grinding and polishing epoxy resin

Visible sanding scratches : Do not skip larger grit sizes and completely remove the sanding marks from each size.

Matte oder milchige Oberfläche: Achte auf einen gleichmässigen Feinschliff und verwende eine geeignete Polierpaste mit dem passenden Polierpad.

Too much pressure and heat: Move the polishing tool evenly and work with light pressure to avoid overheating the surface.

Epoxy resin not fully cured: Do not begin sanding and polishing until the resin has sufficiently cured. Refer to the manufacturer's instructions.
