If you’re planning an epoxy resin project, accurately estimating how many litres of resin you’ll need per square metre is essential for success. Whether you’re an artist looking to coat a surface, a maker embedding objects, or creating a deep pour table, selecting the right resin—and calculating the volume required—can be difficult. This guide compares leading ResinPro epoxy resins for different pour depths and helps you choose the right product to match your project’s requirements, ensuring efficient and stunning results.

Comparing Resins: How Much Do You Need Per m²?

The amount of epoxy resin required per square metre depends directly on the layer thickness you intend to pour. For thin artistic coatings, you’ll need far less than for a deep pour table. Each resin is designed for particular layer thicknesses—so it’s crucial to choose a formula that matches your project’s depth. As a rule of thumb, the volume calculation is:

Resin volume (litres) = Area (m²) × Layer thickness (cm) × 10

For example, coating 1m² to a depth of 2cm requires 2 litres of resin. Select a resin not only for its visual and mechanical properties but also for the recommended maximum pour per layer—it ensures a bubble-free, durable, and clear result.

Visualise the impact of different pour depths with real-world photos and artwork case studies. Each example demonstrates how pour thickness affects total resin volume and surface results, providing inspiration for your project. Choose the appropriate resin for the effect and coverage you desire—from thin, glassy coatings to statement-making deep pour tables.

“Art Pro” – Clear Epoxy Resin for Surface Coating

“Art Pro” – Clear Epoxy Resin for Artists and Surface Coating is purpose-built for artists and crafters seeking glass-like finishes and high clarity. It is ideal for thin coatings (recommended layer: 1.5 to 3 mm) on flat surfaces like trays, coasters, or artwork panels. With its exceptional clarity and non-drip formula, it minimises waste and enables precise control on horizontal artwork. This resin suits those requiring durable, UV-protected finishes with minimal thickness, making calculation simple: for 1mm over 1 m², just 1 litre is needed.

“EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects up to 5cm

When your project demands significant thickness—such as resin river tables or large volume castings—“EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects – Up to 5cm is the solution. Engineered for pours up to 5cm in one application, it enables creation of furniture and large panels with strong UV filters, excellent mechanical resistance, and a low exothermic reaction for worry-free deep pouring. For 5 cm thick casting over 1 m²: expect to use 50 litres of resin. Discover its popularity among our top sellers.

Tips for Project Planning and Resin Coverage

Always measure both area and intended depth with care before beginning. Remember to allow for extra resin (about 5–10%) to account for mixing loss and simple errors. When working with layers thicker than your resin’s recommended maximum, use multiple pours, allowing each to partially cure before proceeding. This reduces risks of overheating, yellowing, or structural issues. For large projects such as tables or artworks with embedded objects, calculate each section’s volume individually and combine totals for best accuracy.

Coverage Planning & Professional Results

Accurately estimating resin requirements saves time, budget, and effort. For the best finish, mix resin with precision, pour at stable temperatures, and level your project base before coating. Consider working with test swatches before starting large surfaces so you can perfect your technique and ensure you achieve the clarity and thickness your project needs.
