Choosing the Right Epoxy Resin for Your Project

Match your resin’s depth and finish to your project needs. For river tables or deep casts, opt for EpoxyTable 5-Five or Epoxytable 10-Ten. Smaller, decorative pours benefit from Trasparente. If you want everything in one, try the River-Table Kit with full instructions included.

Step 1: Prepare Your Surface and Set Up the Formwork

Begin by ensuring your work area is dust-free, level, and well-ventilated. Select an appropriate mould or construct a formwork that matches your project’s size and shape. Seal all internal corners and seams thoroughly—leaks are common early mistakes. Use painter’s tape or a specialised release film to prevent your epoxy adhering permanently to the sides of the mould. Double-check for gaps or potential leak points, especially if building a river table or large cast. Address any issues before you start your pour for a smooth finish later.

Step 2: Measure and Mix the Epoxy Resin

Measure your resin and hardener by weight following the manufacturer’s specified ratio. Mixing ratios vary—Always follow manufacturer’s mixing ratios precisely for optimal results. Pour both parts into a clean container and stir with slow, steady movements for at least three minutes, scraping the sides and bottom frequently. Avoid vigorous stirring to reduce trapped air bubbles. If you wish to add pigments, do so after the initial mix, stirring well to achieve an even colour throughout. Once fully mixed, use the resin promptly, as pot life is limited.

Step 3: Pour the Epoxy Resin Carefully

Slowly pour the mixed epoxy into your prepared mould or over your surface, starting from one corner and allowing the resin to flow and self-level. For projects thicker than 2cm or 5cm, select the matching deep-pour formula, such as EpoxyTable 5-Five or Epoxytable 10-Ten. Thinner coatings for art or embedding objects work best with formulas like Trasparente. Never force depths beyond the recommended maximum per pour to avoid overheating, yellowing, or bubble entrapment. Monitor for leaks in the first minutes, and fix immediately if noticed.

Step 4: Remove Bubbles and Allow to Cure

After pouring, bubbles may rise to the surface. Use a heat gun or torch (safely and sparingly) to eliminate surface bubbles—keep the tool moving to prevent scorching. Maintain your workspace at a steady temperature, and protect from dust while the resin cures. Curing times vary depending on resin type and thickness, usually from several hours up to several days. Do not disturb the piece during curing to prevent imperfections. Most resins are touch-dry within 24 hours, but full strength and clarity may take longer.

Step 5: Demould and Finish the Resin Surface

Once fully cured, gently demould your project. Use a release film or specialist tape for easy removal, which minimises the risk of chips or damage. If the surface requires further finishing—such as sanding, buffing, or polishing—work progressively through finer abrasives before applying a polishing compound. For complete kits, like the River-Table Complete Kit, use the provided pads and polish for best results.

Tips, Troubleshooting, and Common Mistakes

Keep ambient conditions consistent: Work in a dust-free, well-ventilated space and maintain stable temperatures to reduce curing issues. If bubbles persist, check your mixing method or try warming your resin slightly before use. Watch for uneven surfaces—caused by an unlevel table or premature movement. Be patient with depth: attempting to pour too thick in one go can trigger yellowing, warped finishes, or even resin failure. If in doubt, pour in stages and ensure each layer gels before adding the next. Practice good safety at all times.

Best Practice for Consistent, High-Quality Pours

Never rush your preparation or skip PPE. Plan each stage: measure, seal, mix, pour, and cure with care. If you encounter issues—like sticky surfaces or persistent bubbles—review ratios, depth, and working conditions. Experienced users still double-check basics each time to ensure smooth results and reliable finishes.
