How to Make a DIY Concrete Countertop

Concrete countertops can be used in kitchens or outdoors as tops for tables and picnic tables. When constructing a concrete countertop, be sure to use concrete mix that made for countertops, such as Quikrete Countertop Mix.

Start by building a form using melamine coated sheets goods, to prevent the concrete from sticking to the form. It’s a good idea to also apply a thin coat of shoe polish to the inside of the form to aid in releasing the form from the concrete.

The form should be perfectly flat and well supported, so it won’t sag from the weight of the concrete. Use thin wires to suspend a grid of concrete reinforcement wire or rebars in the center of the form.

Mix up the concrete and pour it in the form, spreading the concrete out evenly. Tap the sides of the form with a rubber mallet while the concrete is still wet to release any trapped air bubbles that could mar the surface.

Allow the concrete to harden for a week or more before removing the form. Sand any sharp edges on the concrete and polish the surface if desired.

After the concrete has cured for 30 days of more, apply a concrete stain and sealer to give the countertop a finished look.

Danny Lipford: The easiest way for a do-it-yourselfer to create concrete countertops is an inverted form. This means the bottom of the form will be the top of the counter.

Melamine material works best for this because it has a vinyl coating that will make it easier to remove when the concrete is dry. It’s also a good idea to coat the melamine with clear shoe polish to improve the release.

Inside the forms, a rebar and reinforcement wire grid is created to give the concrete strength. The thin wires that suspend it can be cut off later when it’s completely dry.

Concrete mixes designed for countertops are the best choice for this project. They’re formulated with plasticizers and contain less aggregate—or rocks—than mixes for general use.

After mixing according to the directions, the concrete is spread out in the forms until it is level with the top of the sides. In order for this to be consistent, it is important that the forms be on a perfectly level surface. Tapping the sides of the mold while the concrete is wet will help release any air bubbles that would mar the finished surface.

After the concrete cures for at least 24 hours, the mold can be removed. At this point the concrete can be sanded to remove rough edges and polish the surface. This counter will be used outside, so we’re only removing the rough edges.

After the concrete has cured for at least 30 days, it will be ready to apply stain and sealer to complete the process.


  1. Love this concrete countertop . Danny, is your show not viewed in the Evansville, Indiana area? It was on channel 7 WTVW and I can’t find it anymore. Please let me know.

    • Hi, Parvin,
      If it’s not exposed to water, indefinitely. Water is the catalyst that will make it hard. (Water or high humidity conditions.)
      Thanks for your question!

  2. Guys – I just did a test for a 24×36 / cast-in place / 2″ thick. I used the Quickcrete countertop mix 110680-lb mix to 1-gallon of water (then added another pint+-ish) and found the mix crumply – dry and hard to work with. Also seemed very tough to level and finish. I saw other posts saying they had used closer to 1.5 gallons to an 80-lb bag. The pour you were using was wonderfully soupy compared to what I dealt with. What was your water to 80-lb that you used for the mix on the video? Again – I was using the Quickcrete Countertop mix – tint base – 18 hour – No. 110680 – similar blue bag shown in video. Thanks, Marc

  3. Very similar comment as Marc below. I used more than the recommended amount of water (3.8L) for each bag and the mix was very dry, crumbly, hard to work with. Definitely did not get a nice “flowable” product as advertised. Just keep adding more and more water?? Too much water can weaken the dried product, no? Thanks for the info!

  4. My husband loves DIY projects, and he wants to make a personalized countertop for our family for Christmas. Your how-to guide will really help him, and it’s especially good to know that we’ll need to let the concrete harden for more than a week before we can sand it. With that plus the 30 days after for curing, maybe it can work as a Valentine’s Day present, instead.
