Gathering the Materials You’ll Need for a DIY Concrete Coffee Table

You’ll need to gather the essential supplies to make your own concrete coffee table.

The Base

For the base, you’ll want wooden boards for the tabletop frame. Pine boards work tremendously and are budget-friendly. You’ll also need concrete mixing supplies like:

  • Concrete mix. Look for a mix specifically for countertops or furniture. Regular concrete is too coarse.
  • Water
  • Aggregate like pebbles or crushed stone (optional)
  • Colorant (optional)
  • Mold-release agent like cooking oil to coat the wood base


To reinforce the concrete and prevent cracking, you’ll need:

  • Wire mesh or rebar
  • Wire to secure the reinforcement to the wood base

Finishing Touches

To finish the table, gather the following:

  • Concrete sealer to protect the surface
  • Sandpaper (coarse to fine grit)
  • Concrete wax or finish (optional)
  • Felt pads to place under the table legs

Insight – Achieve a perfectly level surface by screeding the concrete with a specialized tool. Don’t settle for a subpar finish — take the extra step to ensure a flawless result.

How to Make a Concrete Coffee Table: Preparing the Mold 

To form your concrete table, you’ll need to construct a sturdy mold to hold the wet concrete in place as it dries and hardens. For the base, use 3/4-inch plywood cut to the dimensions you want for your tabletop. Secure the boards together at the edges to form an open box. You’ll also want to attach legs to the base so you can move the mold around. Wood boards, metal pipes, or plastic legs all work well.

Preparing the Sides

For the sides of the mold, you have a few options. You can use:

  • Wood boards. Easy to work with but may warp over time. Secure them to the base with wood glue and nails.
  • Plywood. Sturdy but can be expensive. Attach to the base with wood glue and nails.
  • Melamine boards. Smooth, moisture-resistant, and reusable. Glue the edges together with silicone caulk or waterproof wood glue.
  • Metal sheets. Durable and waterproof. Bend to shape and attach to base with bolts.

Whichever you choose, the sides should be at least three inches high to contain the concrete. Be sure to seal any cracks in the mold—you don’t want your concrete seeping out. Once your mold is built, you’re ready to mix and pour your concrete. Take your time and be meticulous—your coffee tables is about to be set in stone.

Insight – Achieving a perfect finish for your concrete project is easy! Once the concrete has slightly hardened, you can apply a smooth or textured finish using a trowel or brush. Don’t settle for a mediocre result when you can create a professional-looking finish with just a few simple steps.

How to Make a Concrete Coffee Table: Mixing and Pouring

Once you have the mold built, it’s time to mix and pour the concrete for your tabletop. This is a messy process, so make sure to wear old clothes and gloves.

Gather Your Supplies

You’ll need concrete, sand, water, a wheelbarrow or mixing tub, a shovel, a trowel, a level, and a float. For a standard four-foot-square tabletop, get about six bags of concrete and three cubic feet of sand.

Mix the Concrete

In your wheelbarrow, combine the concrete, sand, and water. Start with four to six bags of concrete and two to three cubic feet of sand. Add water a little at a time, mixing thoroughly with your shovel after each addition. The consistency should be thick but still pourable. If it’s too dry, it won’t level properly; too wet, and it won’t harden correctly.

Pour and Spread

Pour the concrete into your mold. Use your shovel to spread and distribute it evenly. Tap the sides of the mold with your trowel to release any air bubbles.

Level and Smooth the Surface

Use your level to make sure the concrete is evenly distributed. Screed off excess concrete with your trowel. Once leveled, use your float to lightly smooth the surface. Cover the tabletop with plastic sheeting and let it cure for at least three to seven days before removing the mold. After removing the mold, you may need to sand down any imperfections or uneven areas. Apply a concrete sealant to help protect the surface. Add hairpin legs, and your concrete coffee table will be ready to use!

How to Make a Concrete Coffee Table: Demolding and Finishing

Once your concrete has cured for at least three to seven days, it’s time to unmold your masterpiece. This is an exciting step, as you’ll finally get to see the results of all your hard work!

Removing the Mold

Slowly and carefully pry off the sides of your mold. Use a rubber mallet to gently tap the edges until the sides come loose. Remove any remaining debris from the surface with a damp cloth.


Lightly sand down any imperfections and smooth the edges and surface. Use 120- to 220-grit sandpaper and gently sand in small circular motions. Wipe away dust with a tack cloth.


Apply two to three coats of concrete sealer, waiting two hours between coats. The sealer will protect your tabletop from stains and scratches. Wipe away any drips or uneven areas between coats.

Polishing (Optional)

For an ultra-smooth finish, you can polish your concrete table. Start with 400-grit sandpaper and work your way up to 3,000 grit, wiping away dust after each grade. Then, buff the surface with a polishing compound and a buffing pad. Polishing will result in a glossy, glass-like finish.

Adding Legs (Optional)

If desired, you can attach pre-made hairpin legs, trestle legs, or other table legs to the bottom of your table base. Flip the table over and mark where you want to attach the legs. Drill pilot holes, then screw the legs into place. Flip the table back over—your concrete coffee table is now ready to use.
