Centennial Concrete Countertops

Nobody actually lives on concrete. You live on whatever we sealed it with. That's the part of a concrete countertop that decides your Tuesday: whether a lemon wedge left by the sink leaves a mark, whether the spot in front of the range clouds over, whether wiping the thing down is a two-second job or a small negotiation with a bottle of something special.

The concrete is the straightforward part. We control the mix, the steel, the thickness, and the color, and once it has cured it behaves like a slab of stone as far as your kitchen is concerned. The sealer is where the real choices live. It's the difference between a top somebody babies and a top somebody cooks on five nights a week without thinking about it.

The surface you actually touch

Concrete is porous. Left bare it would drink olive oil, red wine, and the water that pools around a faucet, and it would show you every one of them. So every top we build gets sealed, and what we reach for has more to do with how you cook than with how the kitchen photographs.

Two families cover most of the work. Penetrating sealers soak in and leave the surface feeling like honed stone, matte and natural, the texture still under your hand. Film formers cure into a thin, tough layer riding on top and resist stains harder. Both are food safe once cured. They fail in opposite directions, though, and that's the conversation worth having before we cast anything.

Sealer families, and what living with each one is like

Heat, knives, and the short list of things we'd tell you not to do

Set a hot pan down on any sealed concrete and you're testing the sealer, not the concrete. The slab underneath could not care less. The film or the impregnator cares a great deal, and enough get scorched every year that we say it out loud at the estimate: use a trivet, including for the cast iron you just pulled out of the oven.

Cutting is the other one. Concrete is harder than your knives, so the board protects the blade as much as the counter. Past those two, a concrete top is easy company, whether it's a kitchen remodel in Southglenn or a grill island out back in Piney Creek. Warm water, mild soap, a cloth. Wipe acidic spills instead of admiring them. Keep the bleach sprays and abrasive powders under the bathroom sink. Nobody needs a proprietary cleaner, whatever the person selling it says.

From template to the morning you get your kitchen back

• Template after the cabinets are set and level, never off a floor plan
• Sink, faucet, and cooktop cutouts confirmed against the actual boxes
• Molds built upside down so the finished face cures against a hard surface
• Steel and structural fiber placed for the overhangs and around every cutout
• Cast, cured damp, demolded, then ground and filled until the face reads the way you approved
• Sealed, then given real cure time before anything gets set down on it
• Set on shimmed cabinets, with seams filled and colored on site

Every top we've refinished early came back for one of two reasons. A hot pan set down in a hurry, or a lemon wedge that sat by the sink overnight. Never because the concrete gave up.What our crew lead tells homeowners
