I made this table in mid-2013 to fit a narrow but long space in between two sofas. The base is constructed of 8/4 walnut joined by Dominos which were a life saver in terms of speed (it still took a long time—I opted for two Dominos per joint for stability and to ensure all surfaces were level). The top is a 3/4” poured concrete top reinforced with a metal mesh grid within. This was my first experience working with concrete. It’s a really interesting material, and while I wouldn’t exactly call it easy to work with, it was enjoyable and the results are pretty unique in my opinion. I originally had some concerns that 3/4” for the top would be too thin and that the concrete might eventually crack. After it cured, and now having lived with it through some extreme temperature and humidity changes, I feel pretty confident that it will hold.

Very nice design on the base. I like how you can create something to fit your space and requirements.

Was it a special type of concrete, or just redi-mix?

hoosier, the top is finished first by filling air holes (I learned through this process that concrete guys refer to them as bugholes) with a slurry of portland cement. Then it gets sanded, working up from 100 through 600 grit. Next I applied a 5 or 6 coats of Cheng concrete sealer (if you’re pouring concrete, his site is a great resource with very good instructions – I wish I would have found it earlier in the process). After it’s sealed, it needs wax. I tried to use Cheng’s wax, but had a really difficult time applying, so I decided to use Renaissance wax instead. It has held up reasonably well, but as with any wax, will need re-coating from time to time.

JimYoung, thank you for the compliment. I used Quikrete Countertop mix, although you can use any ready-made concrete for countertops and table tops like this. The reason I chose the special countertop mix is that it seemed to have finer aggregate material in it, so you don’t get any of the chunky rocks in your top and you have a smoother surface that more closely resembles a marble/granite than a piece of poured concrete. I couldn’t find the concrete locally, so I called my local Home Depot and they special ordered a bag for me. It was about $15 and was at the store within 2 days of placing the order.

I am very impressed. The walnut and the concrete seem to compliment each other very well. Good work x

Very pretty, I like the design of the bottom. I might have to steal it for an entry room table I’ve been thinking about…

Don’t bother using wax. Look for a silicone floor sealer. Acrylic products are going to give you the best gloss while polyurethane should stand up a little better for wear. If you don’t ever want to have to bother with it again, just use an epoxy kit.

My parents have a concrete counters in the kitchen and I can’t remember which was they used, but wax is the preferred finish when in contact with food. Used to just buff it on with a high speed buffer. The guys doing the counter tops have no idea what they were doing, half of the work they did cracked within a year, they were pouring it a nearly 3” thick which doesn’t seem like it would have been a problem if the ratios are right and it’s not dried too quickly.

Have your say...
