Choosing the correct epoxy resin is essential for successful casting projects, especially when working at depths greater than 5cm. Using the right product helps to ensure clarity, durability and a reliable cure.
Selecting the Right Resin for Extra-Thick Castings
When your project requires pouring epoxy at thicknesses above 5cm, standard casting resins may not be up to the task. For these deeper pours, a formula designed specifically for thick layers is crucial to prevent issues like overheating or incomplete curing. “EpoxyTable Ten” is recommended for pours over 5cm, offering a composition suited for substantial depth, minimising unwanted heat generation. If your pour depth falls between 2–5cm, EpoxyTable Five is ideal.
Practical Tips for Deep Pour Projects
Before you begin, ensure your workspace and moulds are clean and free of dust to avoid imperfections. Always mix your resin carefully, following manufacturer guidelines for ratios and mixing times—this is vital for deep projects. For large castings, pouring in stages can help maintain clarity and structure if you’re working above recommended thicknesses for your chosen resin. Use a precise spreading tool, such as the Tooth Shaped Spatula, to ensure an even application and reduce the chance of trapped bubbles.
When This Matters
Selecting a resin formulated for thicker layers is especially important for projects such as large river tables, benches, and substantial decorative castings. Trying to use a standard or thin-pour resin for these applications can lead to exothermic reactions, blemishes, or failures in the final piece.
