Step 1: Prepare the Surface and Formwork

A clean, dust-free work area is essential for producing flawless slabs. Choose a flat, stable surface and set up robust formwork (mould) made from materials like melamine, HDPE, or another non-stick board. Ensure all formwork joints are tight and completely sealed with silicone or specialist adhesives to prevent resin leaks.

Cleanliness is critical for resin slabs: Any dust, grease or residue on the mould will imprint onto the resin or cause bonding issues. Wipe down all surfaces thoroughly before starting the project.

Step 2: Mix and Tint Your Resin

Accurate resin mixing is fundamental to achieving strong, clear slabs. Always measure mix ratios by weight as specified by the resin manufacturer. Use separate containers for resin and hardener, then combine and mix slowly to minimise bubble formation.

If colour is desired, introduce pigments after the initial mix. Only use pigments compatible with epoxy resins to avoid curing or clarity problems. Continue mixing until the tint is uniform and no swirls are visible.

Step 3: Pour the Resin Layer

Pour resin steadily into the centre of your mould and allow it to spread out naturally. For slabs up to 2cm use a formula such as “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm for a crystal-clear result.

For slabs 2–5cm thick, opt for “EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects – Up to 5cm. For even deeper pours, such as up to 10cm, “Epoxytable 10-Ten” – Deep Pour Epoxy Resin for Tables, Up to 10cm Casting is suitable. Avoid pouring thicker layers than your chosen resin permits, as excessive depth can cause overheating, cracking, or incomplete curing.

Step 4: Curing, Finishing and Demoulding

Allow your slab to cure fully on a level surface; follow the product’s guidance on minimum and maximum curing times before attempting to demould. Avoid moving the mould while the resin is liquid or gelled to prevent waves and imperfections.

Once cured, carefully remove the slab from the mould. Sand any sharp edges starting with lower grit progressing to higher grits. For premium gloss, polish the surface using fine abrasive pads and polishing compound.

If you wish to simplify project steps or require a ready-to-go bundle, the “River-Table” – Complete Kit for Creating Your First Epoxy Resin Table provides all main materials including polishing pads, silicone, pigments, and detailed instructions fit for beginners or advanced users alike.

Tips and Troubleshooting for Resin Slabs

Pour in layers for thicker slabs: For slabs thicker than your resin’s maximum recommended depth per pour, cast in multiple layers with sufficient curing time between. This helps avoid excessive heat and ensures even structure.

Curing times can vary: Thicker pours and cool environments require longer curing. Be patient to ensure complete hardening and avoid premature handling.

Work temperature matters: Keep your work area within the recommended temperature range to ensure a bubble-free, glossy surface and optimum curing speed. Always wear gloves and follow safety guidance for best results.
