Whether you’re planning your first river table, tackling a live-edge slab project, or creating a statement piece for your home or business, understanding just how much epoxy resin you’ll need is essential for a successful outcome. This guide helps makers of all levels accurately plan for resin quantity, choose the right type for their project thickness, and avoid wasted materials or unexpected shortfalls.

Epoxy Resin Volume: Key Factors, Calculations and Comparison

When working out how much epoxy resin is needed for a table, several factors must be considered. Resin depth and project size are key — a shallow 2cm coating requires far less material than a dramatic deep pour or river design up to 10cm. The main differences between leading table resin products relate to how thick they can be poured safely in a single layer, UV and scratch resistance, and their suitability for beginners or advanced makers.

To calculate the required amount, measure the intended resin area (typically length x width for rectangular voids or river channels) and multiply by the intended depth. Example: a river 120cm long, 20cm wide, and 5cm deep = 0.12m x 0.2m x 0.05m = 0.0012m³, or approximately 1.2 litres (1kg of resin ~ 1 litre). Always add 5–10% extra in case of leaks or imperfect mixing.

“River-Table” – Complete Kit for Creating Your First Epoxy Resin Table

If you are looking for a hassle-free start, the “River-Table” – Complete Kit for Creating Your First Epoxy Resin Table provides all you need — including precise resin quantities for standard tables, pigments, silicone sealant, and a full polishing kit. Designed for both beginners and experienced makers, this kit supports applications from 2cm to 5cm deep, with kit volumes tailored for table surfaces up to approximately 2m². Clear instructions guide you on creating formwork and confidently pouring resin for a consistent, bubble-free finish.

This kit covers everything from measuring out and mixing the right amount of resin to sealing your formwork for flawless edges, offering a simplified calculation process for most popular table sizes and designs. Consider the Complete Kits category if you need an all-in-one solution.

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

The “EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects – Up to 5cm is perfect for projects requiring deep, crystal-clear castings and maximum workflow flexibility. With a low exothermic reaction, it’s suitable for single pours of up to 5cm thick. You’ll want this resin when your table’s core or “river” section is between 2 and 5cm; it holds up well in large pieces (even those up to 1m in length), but for very large pours, casting in multiple layers with a wait of several hours between each is advised to avoid overheating.

Key advantages include bubble-free curing, robust scratch resistance, and strong UV filters for lasting clarity. Find it among our Top Sellers.

“Epoxytable 10-Ten” – Deep Pour Epoxy Resin for Tables, Up to 10cm Casting

If your project requires super-thick pours — like dramatic river tables or statement slabs up to 10cm in depth — “Epoxytable 10-Ten” – Deep Pour Epoxy Resin for Tables, Up to 10cm Casting is the go-to. This specialist resin has a highly controlled exothermic reaction, ensuring safe and even curing in deep applications and minimising the risks of yellowing or bubbles.

Use it where one-pour depth is critical, with extra caution for especially large tables — it remains recommended to pour in layers if the surface area exceeds 1m or the weight surpasses 8kg, leaving 6–8 hours between layers.

“Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm

For covered or thinner tabletops, trays, and detailed finishes, “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm is designed for applications up to 2cm. It provides a flawless self-levelling finish and is backed by scratch and UV resistance with a 10-year anti-yellowing warranty. This is ideal for decorative applications, serving trays, or tabletops without a deep-pour requirement. See more in our multipurpose epoxy resins.

Practical Advice for Calculating and Using Table Epoxy

Start with accurate table dimensions, as both the length of voids/river features and depth determine how much resin you need. Consider the role of wood in your design, as a traditional river table divides space approximately two-thirds wood to one-third resin. Layering prevents overheating in large projects, so always follow the product instructions when working with deep pours, casting no more than the maximum recommended resin quantity at a time.

Choose the right resin for your casting thickness: For river tables or slab pours up to 2cm, “Trasparente” or the “River-Table” kit is perfect; for 2–5cm pours, select “EpoxyTable 5-Five”; and for ultra-thick pours up to 10cm, turn to “Epoxytable 10-Ten”. Don’t forget to account for spillage, edge absorption, and possible sanding or planing after curing. When in doubt, slightly overestimating is preferable to running short midway through your project.

Helpful tips for every epoxy project

Measure twice, pour once! Use masking tape or mock-up forms to verify resin depth before mixing. Always mix a little more than calculated to allow for absorption or loss. Find a kit or specialist resin that aligns with both your table design and your experience level for best, most satisfying results.
