Selecting the right resin for your project is essential, as the thickness of your pour plays a crucial role in the quality and clarity of the finished result. Below, explore which type of resin is recommended for different casting depths and tips to ensure success.
Resin Choices by Pour Depth
The ideal epoxy resin will depend on how thick your intended pour will be:
- Deep Pours (above 5cm): For very thick resin pours—such as river tables—choose a specially formulated option like Epoxytable 10-Ten. It is engineered for depths up to 10cm, preventing excess heat build-up and bubbles.
- Medium Pours (2–5cm): A resin such as Epoxytable Five is reliable for mid-thickness work, ensuring clarity and slow enough curing for self-levelling and bubble release.
- Thin Layers (under 2cm): For surface coatings or artistic top layers, use a resin like Art Pro, designed for shallow applications and producing a smooth, glossy surface.
Using Epoxy Resin Effectively
To achieve a successful cast, always follow resin-specific mixing ratios and temperature recommendations. For deeper pours, pour in a single batch as directed, or, if needed, in layers to avoid overheating. Take care to keep your workspace dust-free and level to guarantee a flawless finish. Slow-curing resins designed for deep pours give you sufficient working time, while fast-setting resins are best kept for thinner applications.
When the Right Resin Matters
Choosing the wrong resin for your pour depth can result in incomplete curing, cracks, or cloudiness. Deep pours require resins designed for slow exotherm and bubble control, while thin layer projects benefit from quick-set options formulated for hard, glossy finishes. The clarity and longevity of your work depend significantly on this choice.
