Deep Pour Resin for Thick Castings Above 5cm: What to Use

Q: Applying Resin in Thick Layers: Best Practices

Check the Pour Depth: Make sure your chosen resin is rated for the total thickness required. For one-off pours up to 10cm, select a product like “Epoxytable 10-Ten”. For slightly thinner but still substantial castings, “EpoxyTable 5-Five” handles up to 5cm per pour. Prepare Your Materials Thoroughly: Measure and mix according to instructions, ensuring both resin and hardener are combined slowly to minimise bubbles. Work in a clean, dust-free environment at the recommended temperature for optimal results. Layering for Extra Thick Casts: For very large or especially complex projects, pouring in several layers—allowing each to partially cure—can improve clarity and prevent overheating. Always allow for curing time between layers as advised by the manufacturer.

Using Deep Pour Resin for Thick Castings Above 5cm

When planning a wood and resin project that requires a thick pour, selecting the correct deep pour resin is essential to achieve a bubble-free, clear finish and long-lasting durability. Let’s explore how to approach resin castings over 5cm thick for tables, art, or decorative features.

Why Use Special Deep Pour Resin?

Standard epoxy resins are typically suited for shallow casts and may overheat, yellow, or fail to cure properly when poured too thick. Specially developed deep pour epoxies, like “Epoxytable 10-Ten”, are designed for castings above 5cm, offering low exothermic reaction and extended working times. This prevents cracking or cloudiness and ensures your project remains strong and visually striking.

When This Matters

Choosing a deep pour resin is crucial for river tables, large centrepieces, or any project where the resin layer exceeds standard depths. Attempting thick pours with the wrong product could risk failed set or disappointing optical results.
