The process of working with epoxy can be thrilling for woodworkers, hobbyists, and individuals involved in DIY projects.
However, sometimes after all the excitement of pouring and admiring the beautiful finish and details set in on your epoxy table,
tiny bubbles may start to appear, and this can be frustrating.
These air bubbles trapped within the epoxy can detract from the overall aesthetic appeal.

Understanding Epoxy Bubbles
Before seeking solutions, it’s important to understand why these bubbles form.
One of the most common causes is the release of air trapped in the wood or the epoxy mixture itself.
Bubbles can also form due to improper pouring, incorrect mixing ratios, or exposure to moisture during the curing process.
While it’s impossible to eliminate all bubbles, minimizing their appearance is achievable by taking the right precautions.
Essential Tools and Materials:
- Heat gun or blowtorch
- Sandpaper (various grits, including fine-grit for finishing)
- Scraper or razor blade
- Polishing compound
- Microfiber cloths
- Safety gear (gloves, mask, eye protection)
Step-by-Step Guide to Removing Bubbles from Cured Epoxy Tables
- Safety First: Put on necessary protective gear to prevent injuries or inhalation of harmful fumes.
- Surface Preparation: Clean the cured epoxy surface with a damp cloth, removing dust and debris.
<li><b>Heat Treatment (Method 1):</b> Using a heat gun or blowtorch, gently apply heat to the bubble area. Start from a distance to avoid damaging the surface. As the epoxy warms up, the bubbles will expand and rise to the surface.
<p><i>Caution: Avoid overheating the epoxy; only apply heat for brief intervals to prevent burning or warping. </i></p>
</li>
<li><b>Scraping (Method 2):</b> Use a sharp scraper or razor blade to carefully scrape away the top layer of epoxy, including the bubbles. Be cautious not to scratch the underlying layers. Sand the affected area lightly with fine-grit sandpaper to smooth the surface.</li>
<li><b>Filling (Method 3):</b> For larger or deep bubbles, you may need to fill them with fresh epoxy. Mix a small batch of epoxy (follow the manufacturer's instructions), apply it to the bubble area, and let it cure.</li>
<li><b>Sanding and Polishing:</b> Once the epoxy is completely cured, start sanding the repaired area with fine-grit sandpaper. Gradually progress to higher grits until the surface is smooth. Finish by applying a polishing compound with a microfiber cloth to restore the original shine.</li>

Additional Tips for Preventing Bubbles:
- Pour epoxy slowly and steadily to avoid trapping air.
- Stir epoxy thoroughly and degas it before pouring to release any trapped air.
- Apply a thin layer of epoxy over the wood surface first to seal any gaps where air might seep in.
- Tilt or vibrate the epoxy mold/table gently as it cures to eliminate bubbles.
- Use high-quality epoxy products specifically designed for tabletops.
- Maintain a clean work environment and avoid pouring in dusty or humid conditions.
