← Back to How do you make corners with resin?


Achieving crisp, well-defined corners in resin work depends heavily on your choice of resin. The right formulation helps prevent overflow and ensures design details are retained during curing.
Why Does Resin Viscosity Matter?
When aiming for ultra-sharp corners, resin viscosity is crucial. Ultra-high viscosity epoxy resin flows less freely, reducing the risk of resin seeping into unwanted areas or rounding off the edges. This makes it ideal for projects like coasters, trays, and fine art pieces where clean lines and definition are a priority.


Practical Tips for Sharp Corners
- Select the right formula: Ultra-high viscosity epoxy, such as Art Pro Deluxe, provides maximum control when working in detailed moulds or along intricate edges.
- Prepare moulds carefully: Use silicone moulds with tight seams and ensure they are well sealed to minimise leaks.
- Pour slowly and monitor: Add the resin gradually, watching how it settles into the corner and using a small tool to guide it if needed.
When Is a High-Viscosity Resin Most Useful?
Choosing a thicker resin is especially important in decorative projects where line definition is important or for any design that highlights moulded details—such as geode designs or clear finish layers. High viscosity helps preserve your creative intent and ensures every edge stays as crisp as possible.
