What is a concrete counter like?
Concrete is an evolving substance. After a month of curing, our concrete has the hardness and impermeability of a granite-like stone. The chemical process that makes concrete hard continues to make it harder for many years. Our concrete can be polished to resemble granite or can have the soft feel of soapstone. As your concrete ages it will subtly change. Over time colors can deepen and intensify and the counter will change to reflect the way you use it.
Is the concrete sealed?
We have sealed your counters against most elements but care should be taken to maintain them. The sealing strategy that we employ allows the concrete to ‘breathe’ as cementious hardening continues for years. As the seal allows for a small amount of vapor transfer, temporary local darkening may occur when steam filled pot lids or hot coffee cups are placed on the counter. This is normal and no cause for alarm.
Will my concrete stain?
We have worked hard to develop a sealer that both maintains the unique look and feel of concrete while providing protection against general fluid contaminants. Concrete’s curing mechanism is alkali in nature, so acids can etch raw concrete. Acids that carry color can stain if they are allowed enough time to penetrate the sealer, so it is wise to clean up spills of red wine, vinegar, lime juice etc. in a timely manner.
How do I clean my concrete?
To clean concrete, use a mild non-abrasive soap. Avoiding amonia, citrus, bleach, and vinegar based cleansers. We recommend Ivory White, Doctor Bronner’s Castile soap, or Simple Green applied with a non-abrasive sponge or cloth. If a stain persists in a localized area, try using a baking soda poultice to remove it. To do this, mix baking soda with water to a peanut butter like consistency. Spread it over the affected area at least 1/4” thick, cover with plastic wrap, and allow to dry. The poultice will extract oil and pigment (like coffee) stains quite effectively. Multiple applications may be required for more stubborn stains.
Can I cut on concrete?
We do not recommend the use of knives on concrete. Although cutting will not affect the function of the concrete, it may scratch the finish, and it will certainly dull the knife. If desired, we can form a place to accept a custom chopping block.
What if the surface becomes scratched?
Should the surface of your concrete become abraded through rough use (from knives or anvils or sandpaper covered bowling balls), we provide a sealer upon delivery of your countertop that can help it restore its sheen. The application is easy and takes only minutes. You can follow the simple instructions on the label for continued maintenance. If you apply a wet sponge to your countertop and notice a darkening or deepening of color it is a good indicator the surface has become porous and should be sealed again. If something more drastic happens, it can always be repaired.
Can I put hot objects on concrete?
We suggest the use of a trivet, yet hot pots may typically be placed on your counters after the concrete has been in place for over 45 days.
Will my concrete crack?
We have developed extremely high strength concrete mixes that nearly eliminate the risk of cracking, however hairline cracks are possible. The majority of cracking, on the rare occasion that is occurs, happens during transportation and can be repaired. While cracking is a possibility, it’s not something we ever hear about happening from our customers.
How much do concrete countertops weigh?
It depends on the thickness and the mix design. At 1.5″ thick typical countertops weigh 18.5 lb per sq ft. At 2″ approximately 24 lb per sq ft. Beyond that we have many ways of reducing weight while maintaining the appearance of a thick slab.
Is concrete appropriate for commercial applications?
Absolutely. Stone Soup has made countertops and bar tops for everything from commercial kitchens to Fenway Park. Concrete is a wonderfully durable material for high traffic commercial applications.
