One of the most important rules for any wood and resin table project is to never exceed the recommended casting thickness for the epoxy resin you’re using. Sticking to this guideline helps ensure a successful, smooth and safe result when crafting your resin projects.
Why Casting Thickness Limits Matter
Epoxy resins are carefully engineered so that each product can cure properly without issues. Pouring resin thicker than recommended can lead to overheating, cracking, yellowing, or incomplete cures. This is due to the chemical reaction that generates heat as the resin hardens—going too thick in a single pour can make this reaction uncontrollable and harmful to your workpiece.
How to Choose the Right Resin for Your Project
Different resins are made for different pour depths. For example, EpoxyTable 5-Five is specifically designed for single pours up to 5 cm thick, perfect for most river tables. If your project is larger, consider a product like Epoxytable 10-Ten, which allows up to 10 cm per pour. Always check the guidelines for your chosen resin before starting, and plan your pours accordingly.
Practical Guidance for Safe Pouring
- Divide deep projects into multiple layers if thicker casting is needed.
- Allow each layer to cure before pouring the next to minimise heat build-up.
- Follow instructions included with beginner kits like the “River-Table” Complete Kit, which are tailored to recommended pour depths for new users.
When This Matters Most
If you’re working with large, deep tables, or incorporating detailed art within the resin, sticking to the right thickness is essential for clear results and structural stability. It’s especially important for beginners, as it makes the process safer and more manageable.
