Facebook← Back to Can I remove bubbles if the resin has already hardened?
Finding bubbles in cured resin can be disappointing, but some surface imperfections can still be improved. Let’s explore the methods available and whether hidden bubbles can be corrected once your project has fully hardened.
Surface Bubbles: Your Repair Options
If bubbles are trapped only at the surface of your resin piece, gentle sanding can remove small raised imperfections. Start with a fine wet/dry sandpaper (e.g., 800–1200 grit) and work evenly, taking care not to damage the area around the bubble. After levelling the surface, you can restore the glossy finish by applying a thin re-coat of clear resin, such as Trasparente. This process helps to recover clarity and a smooth look, giving your project a professional finish.
Dealing with Internal Bubbles
Unfortunately, bubbles that are fully encapsulated inside hardened resin cannot be removed without significant risk to the project. As these are locked in the solid resin, attempts to drill out or cut away the area often result in further visible damage or cloudiness. Prevention, such as careful mixing and slow pouring, is always preferable—in particular for crafts and artwork using specialist resins like Art Pro.
When This Matters: Ideal Projects for Repairs
- Shallow tabletops and art pieces where only the top coat is affected
- Decorative trays, coasters, or jewellery where finishing is key
- Small-scale DIY work where a perfect glossy coat is desired
