Pour Resin Slowly to Avoid Bubbles When Building a Guitar

Why Pouring Slowly Prevents Bubbles

Pouring resin slowly minimises the chance of trapping air in your mix, which can cause unsightly bubbles in the finished guitar body or decorative section. Rushing the pour or pouring from a height agitates the mixture, increasing the possibility of bubbles rising and getting caught. By keeping the pour close to the surface and controlling the flow, you allow air to escape more naturally.

Best Practices for Bubble-Free Resin Guitar Builds

• Mix thoroughly but gently: Stir resin and hardener carefully to avoid introducing air.
• Use a low-viscosity resin: Products like Epoxytable 10-Ten are formulated for deep casting and help bubbles escape easily.
• Pour in stages if necessary: For thick guitar bodies or moulds, consider layering resin to control cure speed and bubble release.
• Use a heat gun or torch: After pouring, gently pass a heat gun over the surface to help remaining bubbles rise and pop.

When This Matters Most

Pores and bubbles are most visible in clear or tinted resin sections, especially on a guitar’s front or resin-filled fretboard details. Taking your time with each pour is particularly important for showpiece elements and high-gloss finishes where clarity is key.
