If you’re finding dimples or fish-eye marks after coating your shelf with resin, you’re not alone. Understanding why these surface imperfections occur is the first step towards achieving a flawless, professional finish.
Why Do Resin Surfaces Dimple or Develop Fish-Eyes?
The most frequent reason for dimples or fish-eyes is surface contamination. Even small traces of oil, dust, fingerprints, or silicone residue can cause the liquid resin to pull away, forming small craters instead of laying flat. Before pouring resin, ensure your shelf is thoroughly cleaned and free from any contaminants.
Essential Surface Preparation Tips
- Clean thoroughly: Wipe the shelf with a lint-free cloth and alcohol to remove any dust, grease, or oily residues.
- Avoid silicone-based products: Don’t use cleaners or tools that may leave behind silicone; these are a common cause of fish-eyes.
- Sanding and dust control: Sand the wood lightly to create a smooth surface, but make sure all the sanding dust is fully removed before you coat.
Taking these measures helps the resin, such as Art Pro clear epoxy resin, flow evenly and bond securely for a reliable result.
When This Guidance Matters Most
If you plan to use resin as a topcoat for decorative or functional shelves, especially in areas expected to see regular use or close inspection, proper preparation is crucial. Dimples or fish-eyes not only affect appearance but can compromise the protective quality of your resin finish.
