Accurate Preparation of Epoxy Resin for Bubble-Free Casting

To prevent the formation of air bubbles during the casting of RESINPRO's Crystal Clear Epoxy Resin, it is essential to follow a proper material preparation process. Before starting the pour, make sure to thoroughly mix the epoxy resin with the hardener, following the manufacturer's recommended ratios. On the RESIN PRO website, you can explore a complete range of high-quality epoxy resins to ensure flawless project execution.

Using a Brush to Eliminate Air Bubbles

After pouring the epoxy resin onto the chosen surface, it is recommended to use a brush to evenly distribute the material. With slow and gentle strokes, the brush helps eliminate trapped air bubbles in the resin, ensuring a smooth and uniform surface. RESIN PRO offers high-quality brushes specifically designed for epoxy resin work.

Utilizing a Gas Torch to Remove Stubborn Air Bubbles

For stubborn air bubbles, using a gas torch can be effective. Gently passing the flame over the resin surface will cause the air bubbles to expand and disappear. It is important to exercise caution and avoid overheating the resin to prevent material damage. RESIN PRO provides high-quality gas torches for achieving a professional result.

Covering and Allowing Bubbles to Disappear

Once visible air bubbles are removed, it is advisable to cover the project with a suitable dome or cloche to protect it from dust and external contaminants. Allow the resin to dry for the manufacturer's recommended time, allowing any remaining bubbles to rise to the surface and disappear naturally. RESIN PRO offers all the necessary accessories to cover and safeguard your projects involving transparent epoxy resin.
