Frequently Asked Questions

Do concrete countertops crack?

soliddesigns.com
Not always, but concrete countertops can develop hairline cracks. These cracks are non-structural and result from the natural shrinkage of the concrete. We reinforce our countertops with a high-tech carbon fiber grid developed specifically for concrete countertops. We reinforce all overhangs and any sink or cooktop cutouts with steel rebar. These reinforcements ensure that no structural damage will occur to the countertops.

How thick are concrete countertops?

Liquid Stone Studios
Our counters are generally cast 2” thick, or more, which gives them a pleasing sense of mass and sets them apart from the common 1 1/2” thickness of most other countertops. This thickness also provides enough material for integral drain boards and integral cutting boards. Drop edges of 8 inches or more may be incorporated for a heavier look, without adding appreciably to the weight, while our backsplashes are usually 5/8” thick.

No other material allows for the many choices of color, texture, shape, and style.

Why does concrete crack?

Cement & Concrete FAQs (Frequently Asked Questions) | Po...
Concrete, like all other materials, will slightly change in volume when it dries out. In typical concrete this change amounts to about 500 millionths. Translated into dimensions-this is about 1/16 of an inch in 10 feet (.4 cm in 3 meters). The reason that contractors put joints in concrete pavements and floors is to allow the concrete to crack in a neat, straight line at the joint when the volume of the concrete changes due to shrinkage.

What colors are available for concrete countertops?

soliddesigns.com

One commonly requested upgrade is a 2” slab which weighs approximately 25 pounds per square foot. Standard cabinetry will easily support these concrete slabs as the weight of the countertops is distributed over a large area.

Will concrete countertops stain?

soliddesigns.com
We seal all of our countertops to ensure water and stain resistance. But this does not mean that they are totally stain proof. Acidic substances such as lemon juice, vinegar, or red wine should not be left on the countertop for more than several hours if spilled to avoid staining. Cutting directly on the countertops or placing extremely hot pots on the countertops may compromise the sealer allowing liquids to seep in and stain the concrete.

Can you cut on concrete countertops?

soliddesigns.com
No, you should not. Cutting on the concrete countertop won’t hurt the concrete, but will damage the sealer, which can affect the sealers ability to keep out water and stains. Cutting boards should always be used when chopping or preparing foods.

Can you put Hot pans on concrete countertops?

soliddesigns.com
Placing hot pans on the concrete countertops should be avoided. Concrete is very heat resistant, but the concern (like with cutting on concrete countertops) is damaging and or discoloring the sealer. We can build in trivets of stainless steel, brass, or copper. This common upgrade is both functional and great looking. Otherwise, you should use hot plates or a hot pad.

Will concrete countertops stain if something is spilled on them?

Smoothcrete
Our concrete is a composite product. It is harder and stronger than regular concrete and is sealed in order to prevent staining. We recommend cleaning any spills as soon as possible from the concrete countertops. Sealing concrete countertops is recommended annually.

Can you cut directly on concrete countertops?

Smoothcrete
Yes, but you will scratch the sealer, so it is not recommended to do so. If you prefer, SMOOTHCRETE can inlay cutting surfaces directly into the concrete countertop to provide you with a cutting surface.

Can concrete chip, flake or crack?

Roy Burch Concrete - Countertop FAQ
Answer: Yes. Corners and edges can chip if struck by a hard object. My countertops have a curved edge to minimize chipping. Hairline cracks can also develop. These are not structural failures, they are inherent to the property of the material. They can be easily filled if necessary with an epoxy filler mixed with same pigment as the countertop.

Question: What makes concrete crack?

Century Cement- F.A.Q.
Answer: Concrete "shrinks" slightly as it hardens. A normal shrinkage rate is approximately 1/8" per 10 linear feet. This shrinkage is caused by loss of excess water from the mix. Obviously, the "wetter" the mix, the higher the shrinkage rate. Control joints should be placed in the concrete at intervals equal to 2.5 times (in feet) the thickness of the slab. For example, a slab 4" thick should have control joints every 10 feet.

Ready Mixed Concrete Co. - FAQ
There are different types of concrete cracks. The most common of these is related to the natural shrinkage of concrete as it cures and dries. Shrinkage cracking can be controlled or "hidden" by following proper jointing techniques. Different factors and conditions can contribute to each type of cracking. It is important to understand these potential causes and take appropriate action to prevent cracking.
