Frequently asked homeowner and designer concrete countertop questions:
Q1: Why consider concrete as a material for interior applications, like my kitchen or bathroom counters?
Concrete is an extraordinary material that is practical, expressive, and aesthetic all at once. From a primal and formless slurry, you can transform it into virtually any shape that becomes a solid mass. The possibilities for creative expression are endless. You can grind, polish, stamp, or stain it. You can embed meaningful objects within it. Learn more about concrete.
Q2: What are the advantages of concrete countertops over marble or granite? How does concrete compare to granite in terms of both cost (per square foot) and surface texture?
The biggest advantage of concrete over natural stones like marble or granite is that it is completely customizable; you can sculpt, mold, and texturize it to your desire. It’s also a material that the average do-it-yourselfer can easily use — creating something original and meaningful while saving money. If you have a concrete kitchen or bathroom counter made for you, the cost will be based on the complexity of the form, the mold-making process, and the desired finish, rather than the size. Material cost comparisons should be done on a project-by-project basis.
Q3: Do concrete countertops have an application in more traditional kitchens?
Yes, absolutely. Style is dictated by design; concrete can adapt to any look and have a “warmer” feel than other natural stones. Edge detailing and decorative inlays can help a concrete counter blend into more traditional environments.
Q4: Can I use concrete countertops in a commercial kitchen?
We are located in California, where concrete counters are allowed in food-service areas, but you should check with your local health department official first before starting any commercial project.
Q5: Would concrete countertops be good for outside use—as in an outdoor barbeque countertop? How will a colored concrete counter hold up in the sunshine?
Concrete is perhaps the most common building material for exterior use on the planet, however polished and pigmented concrete require special consideration when placing outdoors. The effects of freeze/thaw along with the wear and tear from weather and natural elements can degrade the polished surface if proper care is not taken. The UV rays from sunlight can fade some types of pigments, most notably the class of pigments known as “organic.” CX Pro-Formula Concrete Countertop Mix and the NeoMix Original Concrete Countertop System are both safe for use outdoors. Unlike many of our competitors’ products, the synthetic oxide pigments used in our products are color-fast and non-fading, even our reds, greens and blues.
If you live in an area where your concrete countertop will be subject to freeze/thaw conditions, we recommend covering them when not in use during the winter months.
Q6: Can I use concrete countertops as a cutting surface?
As with marble or granite, we do not recommend cutting directly on a concrete surface; it could result in scratches and gouges in the finish of your countertop as well as harm the blades of your knives.
Q7: Can I put a hot pot directly onto a concrete kitchen counter?
Concrete is heat-resistant but is subject to thermal shock if a red-hot object is placed directly upon it. Like granite, the exposed area may flake or chip away if too much heat is applied. In addition, the heat could damage the sealer and wax applied to the concrete surface. We recommend using trivets for hot cookware.
Q8: Can concrete countertops chip, flake, or crack?
Like marble or granite, concrete corners and edges can chip if struck by a hard object. Sealing and rounding the inside corners of a concrete mold, or form, with silicone will ease the edges and prevent chipping. An eased concrete edge is much less likely to chip or flake than a sharp edge.
Q9: Does concrete stain? What type of sealers do you recommend?
Properly sealed concrete should not stain. However, unsealed concrete has approximately the same porosity as limestone and marble. In addition to stain susceptibility, acids (especially red wine, lemon juice, and vinegar) will etch the surface if not cleaned up right away.
Q10: Where can I see more images of concrete countertop work? How can I find a local concrete countertop professional?
You can see a wide range of award-winning and DIY concrete countertop projects in the Concrete Exchange Design Gallery.
