Q: Do concrete countertops stain?
Answer: Yes. Concrete has approximately the same porosity as marble. Acids
can etch the surface -- red wine, lemon juice, and vinegar especially. However,
like aged butcher block or marble, a patina on a cast concrete product can
actually enhance the character of the surface. The nontoxic penetrating
sealer and wax we use will help to resist stains, but are not acid proof.
Cleaning up soon after spills is the best way to minimize staining and etching.
Q: What sort of routine maintenance is required to
keep the finish?
Answer: A light buff with a bit of carnauba paste wax will put a kick back
into the luster.
Q: Can concrete be used as a cutting surface?
Answer: No. Cast concrete is not a substitute for a cutting board. If you
are interested in introducing a cutting surface into the kitchen design
we recommend a removable Poplar cutting board molded into the counter.
Q: Can concrete chip, flake or crack?
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.
Q: Can I put a hot pot directly onto a cast concrete
Answer: Well yes, but-- Concrete is heat resistant but can be 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. We
recommend using trivets for hot cookware.
Q: How do cast concrete countertops compare with granite
Answer: The cost of producing a cast concrete countertop has very little
to do with the size of the piece and everything to do with the complexity
of the form, the mold making process, and the desired finish. Our countertops
are priced for the individual, unique sculptural forms that they are, not
as a commodity product that is priced by the lineal or square foot.
Q: Can I order a countertop in a custom color?
Answer: Yes. When you decide on a color, a sample will be made.
Q: How do I make up for gaps between the countertop
and the wall?
Answer: Backsplashes. Just like a granite installation, rather than scribing
the countertop to the wall, use the depth of a backsplash to make up for
gaps caused by irregularities in the wall. Backsplashes of any material
may rest directly on cast concrete countertops and can be sealed with clear
Q: How are the joints between modules in my countertop
Answer: Clear silicone.
Q: Do you install the countertops?
Answer: Yes. After the countertops have cured for at least 14 days, we will
deliver and install them.
Q: Which sinks and faucet fixtures may I use with
Answer: Under-mounted stainless steel sinks go well with concrete rather
than porcelain. We will need the sink and faucet fixtures at the start of
Q: What is the maximum length for a countertop?
Answer: The longest span that can be made without a control joint is about
eight feet. The joints for longer spans will be precisely located and then
sealed with silicon.
Q: Do I need to reinforce the supporting cabinetry
in order to accommodate the weight of a concrete countertop?
Answer: Generally speaking, no. If the supporting cabinets are single-wall
or particle board, vertical reinforcements may be necessary.
Q: Can I choose the inlays that are cast into the
Answer: Sure, if you provide them. Some people leave it up to us to cast
shells, rocks or other objects into the countertop while others want to
be more involved; it is entirely up to you.
