Concrete kitchen countertops were introduced over a decade ago, and have gained in popularity over the years.They are usually fabricated right in the kitchen.Beware of the overall finish that you are trying to create and realize that creating a consistent finish is hard to achieve with concrete countertops.I’ve seen the same craftsman trying to recreate the same look he achieved the week before for someone else’s kitchen, and the new top is no where near the look of the first kitchen.That is the nature of working with concrete, so you need to know this beforehand.
