How to Get Smooth Resin Cuts

Methodical Sanding for Glossy Edges

After making your cut, it’s vital to refine the resin’s edge gradually. Begin with a coarse sandpaper (such as 400 grit) to level any roughness. Progress to finer grits — 600, 1000, and then 2000 grit — to remove scratches and prepare the surface for polishing.

• Use water alongside wet/dry sandpaper to reduce dust and keep the resin cool.
• Rinse and check your progress regularly to avoid over-sanding.

Polishing for a Clear, High-Gloss Finish

Once the edge feels smooth to the touch, switch to a suitable resin polish or a fine automotive polishing compound. Apply a small amount to a soft cloth or polishing pad, buffing the edge with gentle, circular movements. For best results, a specialised resin such as Liquidissima can help produce a clearer finish, as it’s formulated for minimal imperfections.

Tips: Preventing Chips During Cutting

For smooth edges, take your time with the initial cut. Use a fine-toothed saw or rotary tool, and secure the resin piece firmly to prevent vibration. Rushing increases the risk of chipping or unwanted cracks. Slow, steady pressure and sharp blades yield the cleanest results.
