How Should I Stir Resin and Catalyst Together?

The Right Stirring Technique

To blend resin and catalyst effectively, use a slow, steady stirring motion for several minutes. Be sure to scrape the sides and bottom of your mixing container as you go—this helps incorporate every bit of both components. Continue mixing until the blend appears completely clear and even, with no cloudy streaks or visible separation. Patience and thoroughness ensure a reaction that produces a high-quality finish.

Practical Tips for Bubble-Free Results

• Choose a flat-sided, clean mixing stick for easier scraping and less air incorporation.
• Mix gently to reduce the risk of bubbles—vigorous stirring can introduce unwanted air.
• Allow the mixed resin to sit briefly after stirring; this lets surface bubbles rise and pop before application.
• For demanding applications, select a resin like our “Carbon Resin”, formulated to minimise bubble formation during impregnation.

When Careful Mixing Matters

Meticulous mixing is vital for large pours, intricate moulds, and projects needing structural strength or visual clarity. Insufficiently stirred resin may cure unevenly or develop weak, sticky spots, especially on surfaces like tables, jewellery, or artwork where appearance and durability count.
