How Do I Avoid Mixing Errors and Soft Curing?

Achieving a proper cure with resin and catalyst relies on accuracy and careful technique. Preventing mixing errors will help you avoid issues such as sticky or soft finishes in your resin projects.

Get Your Measurements Spot On

Consistent results begin with accurate measuring. Always use dedicated tools such as precision digital scales or a graduated measuring cup for your resin and catalyst. Follow the recommended mixing ratio as provided by your resin manufacturer. Even a small deviation can lead to an incomplete cure or a tacky finish.

Weigh both components precisely—scales that measure from 1g are ideal.
Check that your workspace is level to prevent spillage or inaccurate amounts in the cup.

Thorough Mixing is Essential

After measuring, mixing the resin and catalyst thoroughly is equally important. Stir gently but thoroughly, scraping the sides and bottom of your mixing container. Insufficient blending can leave pockets of unmixed product, resulting in soft or sticky areas after curing.

Use a clean, flat spatula or mixing stick for best results.
Mix for the time suggested in your instructions, usually a couple of minutes for most systems.

When This Matters Most

Perfect measuring and mixing is especially important for pieces that need absolute clarity, strength, or where the resin makes up the majority of the item (such as casting or art panels). Errors in this step can compromise durability or the overall appearance, so take your time for a flawless result.
