Why Low Viscosity Epoxy Helps Avoid Bubbles During Pouring

What Does ‘Low Viscosity’ Mean?

Viscosity refers to how thick or runny a liquid is. Low viscosity resins are more fluid, so they flow easily into every corner and around obstacles like wood pieces. This runniness allows air bubbles to rise more freely to the surface, where they can be popped or will simply escape before the resin starts to cure.

How Low Viscosity Reduces Bubbles

Bubbles can appear when you mix your resin or pour it over uneven materials. Low viscosity epoxy makes it much easier for these bubbles to travel upwards, as the resin doesn’t trap air as easily as thicker alternatives. Products like EpoxyTable 5-Five are specifically formulated with this in mind, helping both beginners and professionals achieve clearer results with less effort.

Practical Tips for Using Low Viscosity Resin

• Always mix your resin and hardener gently to minimise the introduction of air.
• Pour slowly and steadily, allowing bubbles to escape as you go.
• If pouring deep layers, consider doing it in stages—this gives bubbles more time to rise and be removed between pours.
• If you spot surface bubbles after pouring, a quick pass with a heat gun or blowtorch can help them pop before curing begins.
