We will learn how to make an epoxy river table step by step with many useful tips to create the perfect centerpiece right at home. The epoxy river table has a strong appeal with its eye-catching design and excellent durability. The sturdy epoxy layer helps protect wood from water, temperature and other damaging elements, prolonging furniture life for many years.
What Is Epoxy River Table? Why Choose It?
The epoxy river table is designed from two main components: natural wood and epoxy resin. The wood is cut in a special way to create a gap between the two pieces, then epoxy is poured into this gap to create the shape of a winding river.
The river epoxy table is popular for 3 main reasons:
-
Luxurious aesthetics, each table is a unique work of art that cannot be copied.
-
High durability, absolute water resistance and good bearing capacity to prevent termites and moisture.
-
Possessing a variety of colors, shapes and sizes such as blue, black, yellow or glow-in-the-dark effects.

-
Natural wood: ideally a solid wood slab about 5-7cm thick.
-
Transparent epoxy resin: specialized for casting table tops.
-
Epoxy colorant: blue, turquoise or transparent for river effects.
-
Mold: MDF or melamine coated with silicone.
-
Measuring and mixing tools: measuring cups, mixing sticks, electronic scales.
-
Grinder, sander and sandpaper from coarse to fine.
-
Heat gun or blowtorch.
-
99% IPA alcohol to clean the surface.
-
Finishing oil: polyurethane varnish or wood varnish.
-
Protective equipment: gloves, goggles, masks.

2. Step 2: Prepare the Wood
The types of wood that professional wood workers often use to make epoxy tables today are Walnut, Oak, Maple, and Mahogany.
After choosing the right type of wood, we proceed to do the following preparation steps for how to make a river table with epoxy:
-
Dry the wood completely to 6-8% humidity to avoid shrinkage after finishing.
-
Cut the wood to the desired size, keep a natural contour for the "river" part
-
Clean the wood surface, remove bark, debris and lightly sand.
-
Treat the wood with 99% IPA alcohol to remove natural oils that can affect the adhesion of epoxy.
-
Use clamps to fix the position of the wood pieces to avoid displacement when pouring epoxy.

3. Step 3: Build a Mold
The mold is usually made from MDF or melamine board with a smooth surface. The mold should be about 2-3cm larger than the table top on each side to make it easier to remove the wood epoxy end table has cured.
First, make the bottom and edges under the mold, then use screws to secure wood panels. Next, apply a layer of silicone with a seam of mold to prevent the epoxy from leaking. The silicone should be smoothed with soap to help improve its sealing ability. Once the mold is complete, place the prepared wood in place and check for any gaps between the wood and the mold walls. If there are any, seal them with silicone.
If you notice any imperfections or damage later on, it's helpful to know how to repair an epoxy table top to maintain its flawless finish. This step is especially important when working on how to make an epoxy river table to ensure a clean and professional result.

4. Step 4: Epoxy Mixing
The epoxy is usually made of two parts: one base resin and a hardener. To measure the exact ratio, you have to use a digital scale. The mixture ratio should follow the manufacturer's instructions (usually 1:1 or 2:1).
Mix the epoxy for 3-5 minutes with a clean mixture stick, stirring slowly to avoid making air bubbles. If you’re working on your epoxy river table DIY, you can add color to the epoxy to create a river effect. Blue, turquoise, and jade are the most commonly used colors to create a natural river experience.
After mixing well, allow the epoxy to rest for about 5 minutes so that large air bubbles can get up on the surface and avoid it before inserting.

5. Step 5: Epoxy Pouring
One crucial aspect of how to make an epoxy river table is the layering technique. Instead of pouring all the epoxy at once, divide it into several thin layers:
-
Pour a thin layer of epoxy as a base layer and let it partially cure
-
Pour a second layer of color to create a realistic river effect
-
Pour each subsequent layer until you reach the desired thickness
Note: Each time you pour, use a heat gun or blowtorch at a distance of 15-20cm, moving continuously on the epoxy surface to remove air bubbles. But avoid torching for too long because it can burn. If you want to create a wave effect or color gradient, you can use a mixing stick to gently stir the epoxy in a swirling motion before it starts to harden.

6. Step 6: Wait for Curing
During the epoxy curing process, check regularly for new air bubbles and deal with them promptly with a blowtorch. If you see epoxy leaking out of the mold, wipe it off immediately, as it will be difficult to clean once it dries. If you're unsure of the process, learning how to epoxy a table top properly can help you avoid such issues and ensure a smooth, professional finish.
The epoxy will initially cure in about 24 hours, but it takes 72 hours to fully cure. The ideal conditions for epoxy to cure best are:
-
A stable room temperature of about 70-75°F
-
Low humidity, below 50%
-
No dust or flying insects
-
No strong vibrations or movements

7. Step 7: Sanding and Polishing
After the epoxy has healed, start sanding and polishing:
-
First, use the thick sanding (80-120 grit) to thin the initial surface and remove excess epoxy.
-
Use a thinner sandpaper (150-220) to soften the finished surface.
-
Use Superfine sandpaper (320-400-600) to sand again to ensure a smooth surface before polishing.
After sanding, you need to apply a finish layer to the table surface. Polyurethane oil or wooden varnish are popular choices because they provide additional protection and increase the color durability of the table.
If you're wondering how to build an epoxy river table, applying 2-3 thin coats of finish is essential. Lightly sand between the coats with 600-grit sandpaper for a smooth surface.

8. Step 8: Attach the Legs
When installing the table legs, you should use types with a metal plate to distribute pressure evenly on the table top. Drill screw holes from the bottom of the table but do not penetrate the top. The screw length should be at least 1cm shorter than the thickness of the table top to avoid puncture.
Fix the table legs with specialized screws and check the firmness before use. After installation, check the balance of the table and adjust if necessary.
