What is the best way to achieve a smooth finish on a countertop that has been poured in place?
A. Screed the piece with absolute precision, and have an expert trowel the surface. Timing and “feel” are critical in getting a flat, smooth finish. If you are going to grind lightly and polish after the concrete has cured sufficiently (3 to 4 days or less, depending on your cure time and mix design), a flat surface is imperative to avoid tedious grinding to even out the surface.
