Epoxy river tables have gained immense popularity in recent years for their stunning, eye-catching designs and unique blend of wood and resin. These exquisite pieces of furniture start the same as any solid wood table, but the process behind creating them is far from ordinary. In this article, we will take you through the step-by-step journey of making an epoxy river table, from building the mold to finishing touches.

Building the Mold

The first crucial step in creating an epoxy river table is building the mold. Unlike traditional woodworking, where you simply shape the wood, here, you need to construct a mold for the wood and resin to come together seamlessly.

Building a mold is not a walk in the park; it demands precision and expertise. A dedicated team of craftsmen specializes in this task. They meticulously create the mold, ensuring every detail is perfect. Any errors at this stage can result in the loss of thousands of dollars' worth of resin.

Machining and Refining the Project

Once the resin has been poured into the mold, cured, and is ready for further machining, the process takes an interesting turn. Epoxy river tables seldom come out perfectly flat. Variations can occur due to the curing process, leading to differences in different areas of the project. To counter this, the project needs to be re-flattened, re-squared up, and re-sanded.

Moreover, sometimes, fine detail work is necessary. It's not uncommon to discover a small pocket of air that needs to be addressed. This setback sends the project back to the fills department, where they work their magic, filling in any imperfections. Only when the project is flawless can it move on to the sanding and finishing process.

The Mold Evolution: High-Density Polyethylene

Traditionally, molds for epoxy river tables were constructed using melamine and Tyvek tape. However, in recent years, a significant shift has occurred in the way molds are made. A transition to using high-density polyethylene, a sturdy plastic sheet over an inch thick, has taken place. This material has proven to be a game-changer. Not only is it larger than the table, but it's also 100% reusable.

Cleaning and Reusing the Mold

One of the advantages of high-density polyethylene molds is their ease of use and reusability. Once the table is sufficiently cured and ready to be removed from the mold, the process is surprisingly straightforward.

The sides peel away, the silicone comes off the high-density polyethylene, and the table practically pops out like it's on a non-stick pad. The mold is then cleaned and prepared for the next pour. This shift in mold materials has not only increased efficiency but also contributed to sustainability by reducing waste and minimizing the environmental impact of the process.

Understanding the Timeline

One common misconception about epoxy river tables is the timeline involved in creating them. Many assume it's a quick process – pour resin one week, and you're machining it the next. However, the reality is quite different. The timeline can be as unpredictable as the seasons themselves.

During the summer, the room must be air-conditioned to prevent the resin from overheating. Conversely, in the winter, heating is necessary to keep the resin from becoming too cold. The environment must be 100% climate-controlled and clean to ensure defect-free projects. Ceilings must be covered to prevent dust from falling, and screens are placed on fans to prevent any particles or insects from disrupting the process.


Making an epoxy river table is a meticulous and time-consuming process that requires precision, expertise, and attention to detail at every stage. From building the mold to final finishing touches, each step contributes to the creation of a stunning piece of furniture that seamlessly combines wood and resin.
