Workspace Preparation and Resin Tools in Action

See workspace setups, surface prep techniques, and professional mixing methods that ensure both clarity and durability for your resin tabletop projects.

Step 1: Prepare the Surface and Workspace

Plan your workspace and protect surrounding surfaces. Start by ensuring your timber slab or tabletop is dry, flat, and free of dust. Sand down any rough spots using medium to fine grit abrasives, then wipe thoroughly to remove all debris. Set up your workspace in a dust-free area with good ventilation, making sure it is completely level—an uneven base will cause resin to pool or run.

Cover flooring and nearby fixtures with painter’s plastic. Use masking tape to secure edges you don’t want coated. If casting in a mould or using a live-edge slab, seal the formwork with a release agent or silicone to prevent leaks.

Step 2: Select and Mix Your Resin

Choose your resin based on the thickness you intend to pour. For full beginners or smaller tables, the “River-Table” – Complete Kit for Creating Your First Epoxy Resin Table offers everything in a single package, including pigments and polishing tools. For standard pours up to 5cm, “EpoxyTable 5-Five” provides optimal clarity and bubble-free results. For very thick castings, “Epoxytable 10-Ten” is specially designed for pours up to 10cm and prevents overheating.

Measure your resin and hardener precisely, following the manufacturer’s mixing ratio. Blend components slowly using a drill mixer to avoid introducing excess air. Scrape sides and bottom of your container as you mix to ensure a consistent cure.

Step 3: Pouring and Layering the Resin

Once mixed, pour the resin slowly over your tabletop surface or into the formwork. Aim for a steady, even application to minimise bubbles. For extremely large or deep tables, allow proper curing between layers to avoid defects. If the project exceeds the recommended thickness per pour (5cm for “EpoxyTable 5-Five” or 10cm for “Epoxytable 10-Ten”), pour in multiple layers—waiting 6–8 hours between each to ensure structural integrity and prevent overheating.

If creating special effects or marble finishes, consider the “Stone Effect Collection” kit, which includes pigments and additives for professional results. Work gently with colourants and a heat gun or torch to disperse bubbles and create visual texture.

Step 4: Curing and Demoulding

Allow the resin to cure undisturbed as per the kit instructions (typically 24–72 hours at room temperature). Protect the surface from dust by tenting it with plastic sheeting. Test for full cure before removing from the formwork or unclamping.

Demould carefully—avoid prising up sharp edges, as this can crack or chip the cured resin. Any minor flaws can be sanded out prior to final finishing.

Step 5: Sanding and Polishing the Finish

Begin by sanding the cured surface with progressively finer grit sandpaper (start around 360 grit and finish up to 4000 grit). Maintain a light touch and keep the process gentle to avoid swirl marks. Clean away all sanding dust before moving on.

Polish thoroughly for a crystal-clear finish using specialised polishing cream and pads if included, as supplied in the “River-Table” kit. Work with circular motions and inspect under bright lighting to check for uniform gloss.

Tips, Common Mistakes, and Troubleshooting

  • Measure resin and hardener accurately—incorrect ratios cause sticky or soft patches.
  • Always allow full cure between layers; rushing can result in cloudy or uneven results.
  • Work in a dust-free area and shield the surface as it cures.
  • Take your time with sanding and polish gradually—do not skip grits.
