How to Make a Concrete Table and Embed a Metal Design

Thanks for stopping by to check out how make a concrete coffee table and how to embed metal designs or logos in concrete. This project was a lot of fun and we love how it looks in the living room. The table top is a 2 inch thick slab of concrete. The metal design I used is an outline of Montana, which is where I live. Feel free to embed any custom metal logo or design of your choice! Please refer to the FREE plans and the video tutorial for more details in addition to this post. The total materials/supplies cost for this project (not including tools) is going to be around $145-$165.

Make the Concrete Table Mold

Use a table saw or circular saw to cut the 4×8 sheet of melamine down to size. Measure and use a straight edge to draw out the lines to follow. I used a table saw since it is a lot easier to manage if you don’t have someone else helping out with the project.

Take your time to cut the melamine as straight as possible.

Cut strips of melamine to form the sidewalls. I cut the strips 2 3/4″ wide. You want to add 3/4 of an inch to whatever thickness you want the concrete to be. My concrete table top is 2 inches thick. The extra 3/4 of an inch compensates for the base of the mold. making strips
Cut the side strip lengths on a miter saw.

Assemble the mold. Use 1 5/8 inch long screws for this process. Always pre-drill. Make sure the mold is assembled on a flat surface.

Add reinforcement

Cut a 4×8 sheet of re-mesh to fit in the mold. It should have an inch of wiggle room between the sidewalls around all four sides.

Cut 3/8 inch rebar for extra reinforcement

Add the rebar to the mold. Use rebar tie wire to attach the rebar at each corner. Attach the rebar to the steel re-mesh as well.

Create a metal design or logo

I do a lot of metal work and other projects and so I decided to buy my own vinyl plotter so I could make cool decals and stencils for projects. The Grapthtec CE-6000 is a very good quality plotter that is reliable and professional grade. I’d recommend it to anyone. If you’d rather have stencils made for you I’d recommend getting custom decals and stencils for your DIY projects from my good friend James at www.signsofthemountains.com/diyvinyl.

stencils for metal art
Apply the stencil to metal and trace around it. I chose to use stainless steel to prevent the metal from ever rusting. If you don’t have access to a plasma cutter I’d recommend having a local CNC plasma cutting company help out with cutting the design or logo.

how to make stencils
Here is an example of another metal inlay project I did a few years ago.


I cut out the design using my Hobart 250CI plasma cutter. It is one of my favorite tools in the shop. I’ve had mine for about 7 years and it’s worked great. The newest model is the Hobart 12i Plasma cutter and you can get it on Amazon.

Apply silicone caulk to the front side of the logo. Spread it super thin with a razor blade.


Put the logo in place and let it dry. The silicone will prevent the metal from moving during the pouring process. It will release from the mold easily once the concrete has cured. Seal up the edges of the mold using silicone as well (as seen in the video).

Mix and Pour Concrete!

Mix the concrete in a large mixing tub. I used between 4 to 5 bags of Quikrete 5000 in 80 pound bags. Feel free to add concrete coloring if you’d like. I added Quikrete in charcoal to give my finished table a little darker look. Mix the concrete to about an oatmeal consistency.

adding concrete
Use a bucket to transport the concrete from the tub to the mold. Spread it around the mold with your hands. Make sure to wear rubber gloves.

Making concrete counters
Fill the mold slightly over half full. Then add the reinforcement.

Continue filling the mold. Make sure to vibrate the concrete multiple times during the pour. Lifting the work surface up and down is a great way to vibrate the concrete. I also tap the sides and underside using a rubber mallet. Vibrating the concrete gets the air pockets out of the concrete. The more time you spend vibrating the concrete the better your concrete counter or concrete table will look.

how to vibrate concrete counters
Screed the concrete to level it out once the mold is completely full. Move a straight board in a back and forth motion going from left to right and right to left along the entire mold. Remove excess, and fill in low areas as needed.

De-mold the concrete

Remove the screws and slowly pry away the sidewalls. A chisel or flat screwdriver helps for this process. Always pry against the wood and not against the concrete.

how to remove a concrete table from a mold
Slowly flip the table (with help) and remove the base of the mold. This is what the concrete looked like fresh out of the mold. Let the concrete dry about a day or so before you do any polishing.

Polish the Concrete

I wet polished the concrete using a concrete wet polisher. If you don’t have a concrete wet polisher I would recommend checking out my concrete dining table project because I show how to finish the concrete with an orbital sander. I recommend polishing around the perimeter of the underside of the countertops. This way when people run there fingers along the underside it will feel finished and professionally done. I used 200 grit first, and then finished with 400 grit. You can do the rest of the underside if you’d like, but it is up to you.

polish underside of concrete counter
If you are wet polishing, I’d recommend starting with an 800 grit pad for the top side. This way you won’t expose the aggregate. If you want the rocks and sand in the concrete to show, start with a lower grit pad. I recommend using 5 inch concrete polishing pads.

how to polish a concrete counter
Fill voids in the concrete with a slurry mixture. Create a slurry mixture by mixing portland cement, water, pigment (optional), and acrylic sealer (optional). Rub the mixture into the voids. Let it dry for a few hours prior to sanding or polishing again.

Do a final polishing with 800 grit to remove excess slurry and to polish up the top and sides.

polishing concrete counters
Let the concrete dry. Then use an orbital sander with 220 grit sandpaper to touch up the metal logo if needed.

Seal Concrete Counter

Use a water and acrylic based sealer to seal the concrete. For actual countertops where food is prepared, I like to use Cheng’s concrete sealer. However, for a basic coffee table you can simply use a standard acrylic stone and tile / concrete sealer available at the hardware store or Home Depot. Use 2 coats on the underside to seal it up.

Flip the concrete right side up!

Seal the top and sides. Dilute the sealer about 1 part sealer to 1 part water for the first couple coats. Dilute it a bit less for coats 3 and 4.

how to seal concrete counters
For the last 2 coats you can seal without diluting the sealer. (This is what I do but do what the manufacturer recommends. I do about 6 coats total. Let the sealer dry prior to using the table. The water based sealers do dry pretty quickly.

Build the table base

Build the table base out of 2×4 / 4×4 boards and plywood. I used a Kreg Jig to make the pocket holes. Drill pocket holes on the ends of all 2×4 boards. The measurements can be found in the FREE Concrete Table Plans here.

We love this concrete table. The shelf provides storage and the top has all kinds of room to spread out or kick up your feet.

    Your videos are an amazing help and very detailed. Why dont you use Chengs cement mix? I was just wondering if there would be much of a difference or just a waste of money? Thanks

    • DIYPETE

      Thanks Brad! I use Cheng mix sometime for counters — or the Quikrete countertop mix. It has some great additives that are worth the money. For table I generally use the quikrete 5000 mix as I’ve had great results and tables around the house that look just like the day I made them. If you are considering doing counters — then I might make the additional investment. Cheers!

    How did you attach the concrete table top to the wooden base?

    • DIYPETE

      100% silicon for this project. That way it can be removed when needed. Bolts could be embedded as well if you are up for the challenge. Cheers!
