How to Select Clear Resin by Project Thickness or Layer Depth

Q: Practical Tips for Each Pour Depth

Measure depth accurately: Use a ruler or gauge to confirm your maximum pour thickness before selecting your resin. Pour in stages for thicker effects: For depths greater than one product’s limit, apply in layers, allowing each to cure properly before adding the next. Monitor temperature and mixing carefully: Exceeding the recommended thickness can cause overheating, so mix small batches and pour within guidelines for best clarity and safety.

How to select a resin by thickness or layer depth

Choosing the right clear epoxy resin for your project isn’t just about transparency—it’s also about matching the resin to your planned thickness or layer depth. The type you select will affect your project’s finish, curing time, and ease of use.

Resin Selection by Layer Thickness

For clear casting and surface projects, use the thickness you intend to pour as your main guide:

Up to 2 cm pours: Opt for a multipurpose clear casting resin such as Trasparente. This type is ideal for detailed work, art tables, and most medium-depth moulds.
1–1.5 cm layers: Choose a specialised clear resin like Icrystal for high-gloss, durable surfaces including decorative coatings and smaller castings.
Thin layers (1–10 mm): Surface coatings, art trays, and decorative layers benefit from an artist-grade resin such as Art Pro, which excels at producing glass-like finishes in thinner pours.

Practical Tips for Each Pour Depth

Measure depth accurately: Use a ruler or gauge to confirm your maximum pour thickness before selecting your resin.
Pour in stages for thicker effects: For depths greater than one product’s limit, apply in layers, allowing each to cure properly before adding the next.
Monitor temperature and mixing carefully: Exceeding the recommended thickness can cause overheating, so mix small batches and pour within guidelines for best clarity and safety.

When Layer Thickness Matters Most

Getting the right resin for your chosen depth is particularly crucial if you’re making deep casts (like paperweights or river tables), glossy surface coatings, or thin decorative layers. Using the wrong resin for your depth can lead to incomplete cures, yellowing, or even overheating during the process.
