How to Choose Resin for Different Casting Thicknesses

Q: Match the Resin to Your Project Type

Deep Castings (Over 5cm): For pours exceeding 5cm, choose a purpose-made formula like Epoxytable 10-Ten . This resin is engineered for low exothermic reaction, reducing bubbles and preventing overheating in substantial layers. Medium Castings (2–5cm): Opt for an epoxy marked suitable for moderate thickness. These resins balance working time and cure speed, helping avoid issues that occur with unsuitable products in this range. Thin Coats (<0.5cm): Use resins made for coatings or sealing, as these cure efficiently in shallow layers and provide a smooth, even finish.

Q: Practical Tips for Resin Casting Success

Always check the product’s recommended casting depths before buying. Use a slow-curing resin for thicker projects—it helps prevent trapped air and surface imperfections. Work in a controlled environment to minimise contamination and uneven curing.

Q: When This Matters Most

Choosing the right resin is critical when clarity, stability, or structural integrity are important. Projects like river tables, thick decorative panels, or artistic objects benefit from selecting a resin tailored for the intended depth.

Selecting the right resin for your casting project is crucial, as the thickness of your intended pour affects both the final result and the ease of application. Understanding which epoxy to use ensures clarity, strength, and durability in your finished piece.

Why Thickness Matters in Resin Casting

Resins are formulated to handle different layer thicknesses. Thicker pours, such as those used in large tabletops or panels, produce more heat as they cure. Using a resin specifically designed for deeper pours helps minimise risks like cracking, cloudiness, or overheating.
