How to Fix Dips in a Dry Resin Surface

Noticed uneven patches or shallow dips after your resin project has cured? It’s common and can be fixed with the right approach. Here’s how to restore a smooth, level resin surface.

Identifying and Preparing the Area

Start by inspecting your dry resin for dips or low spots. Mark these areas so you can focus your repair. For deeper dips, lightly sand the affected area using a fine-grit abrasive pad to feather the edges and help new resin bond smoothly. Remove dust thoroughly—use a lint-free cloth or a vacuum before proceeding with a new coating. For any raised or stubborn dry resin spots, a scraper designed for resin, such as the Scraper for Paint & Dry Resin Removal, can be helpful for careful levelling before sanding.

Filling Dips with Epoxy Resin

For shallow dips, prepare a small amount of clear epoxy like Art Pro and pour a thin layer just over the affected area, or across the whole piece for a seamless look. The dense, non-drip formula of Art Pro helps you achieve a level, even coat with good self-levelling properties. Take care to avoid over-pouring, as excessive resin can create new unevenness. Allow the resin to fully cure according to its instructions—typically 12–24 hours.

Finishing and Polishing for a Glossy Surface

Once the recoated resin is fully set, lightly sand again if needed to ensure overall flatness, using progressively finer grits. To restore a professional gloss, apply an epoxy-specific polishing system such as the Epoxy Polish. For best results, use the recommended pad holders or machine polishers rather than only a cloth, as these tools provide the friction needed for a mirror-like shine. Buff until the surface is uniform and glossy.

When This Matters Most

Fixing resin dips is crucial when you want a flawless finish for functional or decorative items like coasters, trays, or tabletops. Small imperfections are often visible under light—re-coating and polishing ensures your project looks its best and feels perfectly smooth.
