Choosing the Right Resin for Height Increases

Deep-pour epoxies formulated for thick casting are essential when raising tank heights significantly. These products manage heat and provide a bubble-free, glass-clear finish, making them ideal for demanding table and design projects. Consider resin characteristics such as viscosity, working time, and yellowing resistance based on your project’s requirements.

Step 1: Build and Seal the Formwork

Begin by constructing a form around your tank area with strong, non-porous materials such as MDF or coated plywood. The walls must be tall enough to accommodate the desired raised height. Ensure all joints are tight and use a silicone sealant to close any gaps, preventing resin leakage during pouring. For easier demoulding later, consider lining the inside of your form with release tape or film.

Always check compatibility between resin and substrate material to avoid adhesion or curing problems. The formwork must be fixed and level to guarantee an even resin surface.

Step 2: Prepare and Mix the Resin

Carefully measure the required amount of resin and hardener based on your tank’s new volume. Deep pours require products designed for high volume applications, as standard resins may overheat and crack. For pours up to 10cm thick, choose “Epoxytable 10-Ten”; for up to 5cm, use EpoxyTable 5-Five.

Mix thoroughly in a clean vessel, scraping edges and bottom. Work in a dust-free, well-ventilated area to limit contamination and fumes. Allow the mixed resin to rest briefly to dissipate bubbles.

Step 3: Pour in Stages to Achieve Desired Height

If your target height exceeds the safe single pour depth of your resin, build up the height in stages. Pour the first layer, allow it to reach a firm gel state, then pour the next. This approach minimises overheating and ensures a strong, clear finish.

Allow sufficient curing time between layers to prevent overheating. The River-Table Complete Kit is especially useful for beginners, combining resin, hardener, and silicone sealant for smooth multi-stage projects.

Step 4: Finish and Release the Raised Resin Tank

Once the final pour has fully cured (this may require several days for very deep tanks), carefully remove the formwork. Use gentle pressure to avoid chips or fractures at the edges. If any sharp lines or slight imperfections remain, lightly sand and polish using a dedicated polishing cream.

For intricate raised sections or small scale projects, “Liquidissima” resin offers extended working time and a crystal-clear finish, perfect for detailed edges or custom inlays.

Tips, Pitfalls, and Troubleshooting

Deep pours require products designed for high volume applications; using standard art resin for thick layers can cause yellowing, cracking, or incomplete curing. Always pour in a stable environment with minimal vibration and a consistent room temperature.

Address air bubbles with gentle torching or warming, but avoid excessive heat. If you notice any cloudiness or softness in a layer, let it fully harden before adding another.

Safety and Preparation for Resin Tank Raising

Personal protective equipment such as gloves, eye protection, and an apron should be worn at all times. Working cleanly and waiting for full cures between steps will deliver professional, durable results when raising any resin tank structure.
