Bubbles can spoil the appearance and integrity of your resin coating, making it essential to address them right from the mixing stage. With the correct approach, you can achieve a flawless, glass-like finish.
Understanding Bubble Formation
Bubbles typically arise during the mixing process when air becomes trapped in the resin and hardener. They may also appear while pouring or if the environmental conditions are too humid or cool. Using a medium viscosity product such as Art Pro epoxy resin can minimise bubble retention due to its balanced flow characteristics.
Proven Techniques for Bubble Removal
- Mix Carefully: Stir resin and hardener gently with a flat stick, scraping the sides and bottom, for at least two minutes. Quick, vigorous mixing increases trapped air.
- Pour in Layers: Pouring resin in thin layers (1–10mm with Art Pro) allows bubbles to rise and escape before curing.
- Use Heat: After pouring, gently sweep a heat gun or torch across the surface—moving constantly to avoid overheating—to encourage bubbles to rise and pop. Avoid using excessive heat or holding the torch too close, as this can cause yellowing or surface defects.
When Bubble Elimination Matters Most
Bubbles are especially noticeable in artistic applications—such as coasters, trays, or art panels—where clarity is key to the finished look. Prompt bubble removal is also crucial for surfaces exposed to daily wear, ensuring not only an attractive appearance but also long-term durability.
