What is the Difference Between Casting and Penetrating Resins?

Penetrating Resins: Purpose and Use

Penetrating resins, such as EpoxyWood, are designed to soak deeply into the wood fibres. This allows for effective restoration and reinforcement of aged or dry wood. When applied, the ultra-low viscosity resin absorbs into cracks and pores, binding loose fibres and helping to waterproof and strengthen the structure. Penetrating resins are ideal for jobs like restoring weathered outdoor furniture, marine woodwork, or reinforcing wooden surfaces that have suffered from deterioration.

Casting Resins: Creating Decorative Features

Casting resins are formulated for creating thick, clear or coloured layers, often seen in dramatic projects such as river tables or thick resin inlays. Products like EpoxyTable 5-Five and “Epoxytable 10-Ten” enable deep pours—from 5cm up to 10cm in a single application—without risk of overheating. These resins are engineered for transparency, reduced yellowing and bubble-free finishes, making them the go-to choice for decorative tabletops, casting art, or encapsulating objects in resin.

When This Distinction Matters

• Wood restoration: Choose a penetrating resin to reinforce and protect old wood, especially where durability and moisture resistance are priorities.
• Creative projects: Opt for a casting resin when you wish to add volume, clarity and aesthetic flair to your woodworking—ideal for river tables or large resin features.
