Here are concrete answers to the questions we get asked the most – and a great way to learn more about our concrete countertop business in Ottawa. From concrete kitchen countertops to kitchen islands and vanities, an Ottawa-made concrete counter can be the smartest (and most stylish) solution for your interior space!
How much does concrete weigh?
Concrete weighs 140 lbs/cubic ft. or 18 lbs/sq ft for a countertop that is 1 1/2” thick. This is very comparable to Marble and Granite so no extra support will be required for your cabinets. We also make GFRC concrete which is glass reinforced, so we can reduce the weight by going down to less than 3/4”. This makes brings the weight down to under 8lbs a square foot!!!! Amazing stuff.
Does concrete stain?
Yes normal concrete will stain, however we take extraneous measures to reduce the chances of this happening. We use very dense concrete that is much less porous than normal concrete. We also treat the concrete surface with reactive sealers that bond to the matrix of the concrete.
Can I put a hot pot on my counter?
Like most other materials, care must be taken as heat will affect the surface by marking, etching or discoloring the sealers used to protect the concrete. A possible solution or alternative to avoid damage would be to use stainless steel trivets that are recessed at key locations into the countertops such as next to the oven and sink.
Can the tops be scratched?
Yes! Because the sealers are sometimes a topical coating of urethane and epoxy it is not advisable to cut directly on the surface. A cutting board should always be used which can be an integral part of the counter design.
What color options do I have?
This is endless!! Any one of Benjamin Moore’s colors can be used to color the concrete. A mix of dry and liquid pigments are used to create the desired effect along with colored aggregates, acid stains and tinted sealers. In other words, the sky is the limit. We don’t guarantee a perfect match, but we will be close!!!
How much will it cost?
Many people think that concrete is inexpensive, which would be true if we were pouring a sidewalk. With the addition of Pozzolans, add mixtures, aggregates, pigments, sealers and decorative elements, it doesn’t take much to drive the material costs of concrete up. But the material is only a small % of the cost. Onsite templating, consultation, forming and pouring along with processing, sealing and installation go into making up a price. A full quotation and contract will be provided for your approval prior to the initiation of any project.
What kind of sink can I use?
Integral sinks can be formed into the concrete and can be based on standard sink designs or customized using your imagination. Vessel sinks can also be used or formed in concrete along with under mount or top mount sinks. We can work with you to come up with the best solution for your needs.
How do I care for my counters?
Countertop care and upkeep is reduced because we use high end Reactive sealers. There is no waxing required as waxes do little to protect against staining and etching. Clean up requires the use of mild soap and warm water only. It is best to avoid abrasive soaps, pads and caustic cleaners that may mar or scratch the surface.
