Ocean Table with Concrete & Epoxy

This project is by Bob from I Like To Make Stuff. This DIY project not only showcases beautiful craftsmanship but also allows you to bring a piece of the beach into your home decor.

With a combination of concrete and epoxy resin, you can create a stunning table that resembles a cross-section of the ocean. Let’s dive into the step-by-step process of making this unique piece.

Step 1: Gather Your Materials

Before diving into the project, it’s important to gather all necessary materials and tools. Here’s what you will need:

  • Heart pine slab for the legs
  • Melamine for the concrete form
  • Quickrete 5000 concrete mix
  • Clear table top epoxy resin
  • Nitrile gloves
  • Plastic mixing buckets
  • SawStop cabinet saw
  • 8″ dado stack
  • Dewalt 20v drill driver combo
  • Evolution miter saw
  • Countersink drill bits
  • Orbital sander
  • Shop Fox hanging air filter
  • 2HP dust collector
  • 1 micron bag
  • Digital angle gauge
  • Danish oil for finishing

Ensure you have safety gear like eye protection, ear protection, a respirator, and a first aid kit handy to make your project safe and enjoyable.

Step 2: Create the Concrete Form

The first step in this project is to create a mold for the concrete. Bob used melamine, which is ideal for this purpose as it prevents the concrete from sticking. Here’s how to build the form:

  • Cut several pieces of melamine for the sides and a square piece for the bottom. The size should be suitable for a small end table.
  • Screw the pieces together tightly to avoid any leaks during the pouring process.
  • Make sure to cut smaller pieces of melamine to create inset spaces for the legs.
  • Use CA glue to secure the corner pieces in place.
  • Seal all seams and edges with silicone sealant to prevent concrete from leaking out.

Step 3: Mix and Pour the Concrete

Once the form is ready, it’s time to mix the concrete. Bob chose Quickrete 5000 for its durability. Follow these steps:

  • In a mixing bucket, combine the Quickrete with water according to the instructions on the bag until you achieve the desired consistency.
  • Lift one side of the form to create an angle that mimics a beach slope.
  • Start pouring the concrete into the form, packing it down to eliminate air pockets.
  • Shape the concrete to create a beach-like texture, with one side thinner and the other thicker.
  • Use the orbital sander without the sanding pad to help remove air bubbles from the surface.

Step 4: Prepare the Legs

While the concrete cures, prepare the legs of the table. Bob used reclaimed heart pine for this part:

  • Cut the heart pine to the desired leg size, ensuring to remove any rough edges.
  • Sand the legs to remove dirt and imperfections.
  • Cut additional pine strips to serve as cross braces between the legs.

Step 5: Pour the Epoxy Resin

After the concrete has cured for about 48 hours, it’s time to pour the epoxy resin. This stage requires precision:

  • Clean any leftover concrete residue from the form to ensure a smooth finish.
  • Mix the epoxy resin in a one-to-one ratio, following the manufacturer’s instructions closely.
  • Add blue dye to the resin to achieve the ocean-like color, adjusting the amount to your preference.
  • Pour the resin over the cured concrete, making sure it fills all corners and covers the surface completely.
  • Use a heat gun to pop any air bubbles that rise to the surface.

Step 6: Final Layers and Curing

After the first layer of epoxy has cured, you may need to apply additional layers:

  • After four hours, mix another batch of epoxy and pour it over the first layer.
  • If cracks appear, carefully fill them with the new mixture and use the heat gun to remove any trapped air bubbles.
  • Let the final layer cure for about two days to ensure it hardens properly.

Step 7: Removing the Form

Once the epoxy has fully cured, it’s time to remove the form:

  • Unscrew the panels of the form carefully, starting with the sides.
  • Be cautious with the corners as they may require some chiseling to free the epoxy.
  • Use an orbital sander to smooth out the surfaces, being mindful to maintain clarity in the epoxy.

Step 8: Assemble the Legs

Now, it’s time to assemble the legs and attach them to the table:

  • Create an X-shaped bracket with the cross braces for added stability.
  • Use a crosscut sled to cut the necessary slots in the legs for the X braces.
  • Glue and screw the legs into place, ensuring everything is aligned and square.
  • Allow the glue to dry completely before moving on to the next step.

Step 9: Sanding and Finishing Touches

After the legs are secure, it’s time to finish the table:

  • Sand all surfaces with progressively finer grits up to 1500 grit for a smooth finish.
  • Use polishing compound to achieve a glossy surface on the epoxy.
  • Apply Danish oil to the wood legs to enhance the grain and protect the wood.

Step 10: Final Assembly

Once everything is sanded and finished, it’s time to complete the assembly:

  • Place the top piece onto the legs, ensuring it fits snugly.
  • Since the weight of the top holds it in place, there’s no need for additional fasteners unless desired.
  • Stand back and admire your ocean table, which is sure to be a conversation starter!
