Concrete kitchen countertops have their own advocates and fans. More and more, I find articles and blog posts about concrete counters, how to cure them, and how it solidifies and ages with a certain alchemy. It can cost the least among the many countertop materials options. But there are tricks and you’ll have to decide whether you want to try making a countertop on your own as part of a remodeling effort, or have a professional pour it.
The San Francisco Chronicle ran an article last year in which the writer claimed to create a three by eight-inch kitchen counter using only $36 in materials. Fu-Tung Cheng, the Bay Area designer quoted in the article, has even published a book and DVD called Concrete Countertops Made Simple. You simply mix up the stuff and when it has the consistency of oatmeal, it’s ready to pour.
Citing the benefits, Cheng reports having the same concrete countertops he first poured in his home more than 30 years ago. On the negative side, Cheng says, if you the concrete isn’t cured correctly, it can be prone to cracks. And, it can stain easily from acidic liquids from vinegar, fruit, or wine.
Estimating the Cost of Concrete Counters
If you choose to have a professional install them, you’ll typically be charged by the square foot for concrete counters. You’ll probably pay between $70 and $150 a square foot, although some contractors include installation in the cost. Curing and polishing must be done in the first three days or so or the concrete will harden to a toughness you won’t be able to work with.
The most exacting job is in creating the mold. It must be smooth and watertight or it will leave unwanted impressions in the countertop, according to Instructables.
