What You’ll Need

• “River-Table” – Complete Kit for Creating Your First Epoxy Resin Table — all-in-one kit including epoxy resin, pigments, sealant and polishing kit for a seamless start.
• “EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects – Up to 5cm — for those tackling thicker or larger areas.
• “Epoxytable 10-Ten” – Deep Pour Epoxy Resin for Tables, Up to 10cm Casting — ideal for very deep river sections or dramatic designs.
• MDF Board Base for Epoxy Resin Table and Art Projects — provides a stable work surface for your project.
• Wood slabs (e.g. oak, walnut, or other hardwood)
• Formwork materials (acrylic, melamine board or HDPE sheet)
• PPE (gloves, eyewear, respirator for safety)
• Mixing containers, stirring sticks and clamps
• Sanding and finishing equipment (various grit sandpapers, polishing machine if available)

Step 2: Build and Seal Your Mould

Construct a formwork (mould) from melamine board or similar material, sized to fit your table. The walls should be sealed tightly at every corner—use clamps to hold everything steady and check for gaps. A release agent or tape should be applied to the inside surfaces to prevent the resin from sticking. This is crucial for removing your project after curing.

If you are using the “River-Table” – Complete Kit for Creating Your First Epoxy Resin Table, the included silicone rubber is designed for easy and reliable sealing of your formwork edges, minimising any risk of leaks.

Step 4: Curing and Demoulding

Allow the resin to cure fully rather than rushing the process. Temperature and humidity affect cure times, but most deep pour epoxies will need at least 48–72 hours to become firm enough to demould. Check manufacturer guidelines for exact timing. Do not move or disturb the piece until it is fully cured. Once set, gently release it from the mould edges and lift it free.

Tips, Common Mistakes and Troubleshooting

Always wear gloves and eye protection when mixing and pouring resin. Make sure your workspace is protected from dust and drafts—particles settling into wet resin are difficult to fix.

Calculate total resin volume before you start. Avoid overfilling the mould, which can cause overflow and waste. For deep pours, monitor for temperature build-up and be patient with curing times to prevent bubbles or cracks. When sanding, keep the surface damp or use extraction to avoid airborne dust. If in doubt, test processes on scrap material before attempting your final table.
