Facebook← Back to How to calculate the amount of resin for a table coating?
For many creative and practical table projects, selecting a resin with a low exothermic reaction is essential when casting layers up to 5cm thick. This ensures stress-free curing and clear professional results, particularly on larger surfaces.
What Is Low Exothermic Resin—and Why Does It Matter?
Low exothermic epoxy resins are specialised formulations designed to minimise temperature rise during the curing process. In deep castings, excessive heat can cause warping, bubbles, cloudiness, or even cracks. Using a resin with a controlled exothermic reaction, such as EpoxyTable 5-Five, allows for deep, bubble-free pours up to 5cm thick without risking the integrity or clarity of your finished piece.
How to Pour Deep Layers Safely
When pouring resins up to 5cm, it’s important not to exceed the recommended maximum thickness in one go, particularly for large projects over 8kg. In such cases, consider layering multiple pours to prevent overheating. Prepare your mould or formwork thoroughly, ensure level positioning, and carefully mix your resin and hardener by weight—most deep pour resins like EpoxyTable 5-Five use a ratio such as 100:55 by weight. Allow enough time for each layer to reach partial cure before adding the next, supporting strong adhesion and a clear, seamless finish.
Practical Tips for Buying and Use
- Choose a product specifically labelled for deep pours up to 5cm to ensure both safety and clarity.
- Purchase slightly more material than your calculation suggests to accommodate for formwork sealing and minor spillages.
- Consider complete kits, like the River-Table kit, which provide resin, sealant, and step-by-step instructions—ideal for beginners or anyone looking for a reliable outcome.
When This Matters Most
If your project involves thick river tables, embedded objects, or large, clear castings, opting for a low exothermic deep pour resin is vital. This approach minimises the risk of curing faults and ensures a resilient, professional-level result.
