Concrete Dining Table





Introduction: Concrete Dining Table

About: I have been taking things apart and putting them back together since childhood. It has long been my dream and effort to make my own way by producing a product of my/our own.

I built this table in 2007,
I built just one each, of the dining table, a computer table, and several coffee tables. My intention at the time was to make and sell these, I never succeeded in selling any, but I later decided to make and sell the legs, which can be seen at

The table top is 1-inch thick steel reinforced concrete.

I'll cover the legs in another post.

Step 1: Detail

The table edge is 1/8 x 1-inch stainless steel, the surface is ground and polished concrete.

Step 2: Frame and Reinforcement Construction

I bent the stainless flat bar around a wood and steel mold, welding the ends to form a continuous band.

The steel reinforcement consists of 3/16" cold steel round bar on approximately 2" centers in two directions. Every round bar intersection is welded. Also the ends of these are welded to the stainless flat bar edge of the table.

Nuts are also welded to the bars to provide attachment points for the legs.These were stainless acorn nuts placed to be flush with the bottom surface. Before pouring the concrete, I filled these nuts with melted candle wax so as to not fill them with concrete. I later melted the wax with a soldering iron tip and then blasted it our with compressed air.

The frame thus created becomes an integral form into which the concrete is poured.

Step 3: Polishing

The polishing is done with these diamond impregnated resin discs. These are velcro backed flexible abrasive discs which are really quite wonderful. There are about 8 different grits that you have to work your way through.

You can get a hand held unit, there's a brand called flex, pretty labor intensive and leaves an imperfectly flat surface, which is fine for a one off, but I was wanting to make and sell these tables. I found this machine, called a flatmaster mini, I couldn't afford it, but I called the guy that made them it and talked him into selling me just the guts and I built up the rest of it , mounted a motor, some skate board wheels, switch, water inlet etc. I have since removed the motor to make another tool.

If you do this wet as opposed to dry then there is no dust or inhalation hazard.

The aggregate or rock, can be chosen for it's color, and broken up glass substituted for the rock, is particularly beautiful.

    Incredible concrete table. Just the thing I was looking for. Too bad that you live in States, we could try make a business here in Europe... (I have some ideas...only another kind of table...)

    This looks incredible, great work.

    If I may be so bold as to ask; what is the mixture and ratios of the concrete? And also, what is the ratio of concrete to aggregate?

    Kind Regards, Brad

    Thank you very much,

    I can't find any notes I may have made, but I can tell you what I remember about the mix.
    The larger rock in this table was 1/8" I also used sand with a range of particle size, portland cement and water, maybe some powder cement color.
    I don't think I used any additives like water reducing agents or fiber.
    I can't tell you ratios, but I was doing my best to keep the water to cement ratio low, and vibrated the table to facilitate the thicker mix.
    I certainly had not yet perfected the process. I imagine that nowadays there is a great deal more information available with all the concrete counter tops that folks are making.

    Thanks, it was commercial in that it was my intention to sell these, which did not pan out. though I do still make and sell the legs, for which the table has been a great model for photographing the legs.

    It's beautiful and I wouldn't rush to put away the frames just yet! Approximately how much does the table weigh?

    Thanks, i,ve never put it on a scale, but it should be about 250 lb

    Thanks, please check out our website to see more of the legs.

    I make the legs in 10 different heights. I will post again about how I make the legs and also about how we make the upholstered benches.

    Yes I looked at your website yesterday, love your work shop and design, really inspiring stuff! I can't wait to see more! please enter these into contests! I have won a few from here, it's pretty cool!

    Will do, I am new to instructables, and very impressed. One of my customers directed me here with a post that included our legs.

    If you need any help, this community is full of helpful people, and i'll offer any help I can as well. BTW its always nice to see a fellow Californian on the boards!

    yes indeed, seems to be a genuinely supportive and friendly community of sorts here, Im in Ventura

    nice! I've wanted to do a shop table out of concrete and this just cemented that idea. (forgive the pun),,,,,,,,,,
