ABSTRACT:
A cementitious slab first has generally straight intersecting lines drawn thereon and the surface of the slab is thereafter cut in order to form narrow shallow grooves therein extending along the previously drawn lines. The entire upper surface of the slab is then washed with an acid wash, neutralized and then pressure washed. A first stain coat is then evenly applied to the upper surface of the slab including the grooves and a second stain coat is thereafter applied to at least some of the discrete areas of the upper surface of the slab in an uneven manner with the second stain being darker than the first stain to thereby render a mottled appearance to the upper surface of the slab. Thereafter, the entire upper surface of the slab including the grooves may be sealed.
