Cast in place concrete counter tops are built right on site. We build the mold on top of the cabinets, or, as in this case, on the stone base. This was a split level counter top, with the bar set up higher. Once the mold was built, we placed a wire mesh reinforcement down, mixed in the Kahlua pigment into our cement mix, a process that is called integral coloring, and poured it out. As the concrete was drying, we passed over it repeatedly with a steel hand trowel, smoothing it out. We let it sit and cure for about five days for it to properly harden and push out all of the moisture in the mix then we protected it using a solvent based acrylic sealer which tends to deepen the color and create a glossy finish.
