Preventing bubbles in deep cast resin projects like river tables is key to achieving glossy, clear results. Simple steps taken before pouring can make a world of difference and save significant time in finishing.
Mastering Your Mixing Technique
The way resin is mixed directly influences bubble formation. Stirring too vigorously can trap extra air. For best results, use a specialised tool such as an Anti Bubble Mixer and employ gentle, thorough movements. This approach pulls fewer bubbles into the blend and disperses any that do appear.
- Stir slowly, scraping sides and bottom of the container.
- Avoid high-speed drills or whisks designed for other materials.
- Pause periodically to let bubbles naturally rise to the surface before pouring.
Choosing Products Designed to Minimise Bubbles
Opt for a deep cast resin formulated for bubble prevention. Low-viscosity resins, like Epoxytable 10-Ten, allow trapped air to escape more easily. These resins offer a longer working time, giving bubbles more opportunity to rise out before the cure begins.
- Check specifications for working time and suggested pour depths.
- Pour in manageable layers if tackling projects thicker than recommended for a single pour.
When This Matters Most
Bubbles are most problematic in clear and decorative pieces, where every flaw is visible. Projects like large tabletops or river pours benefit most from proactive bubble prevention, as post-cure fixes are tricky and time-consuming.
