Abstract
A structural surface such as a wall or pavement related to a building has a patterned layer of stones, which externally retains the texture of the stones. The surface is given a coating of adhesive. A mask of the desired pattern is placed on the adhesive coating. Stones of one characteristics, e.g. color or size, are applied over the mask and adhere to the adhesive layer where the adhesive remains exposed through openings in the mask pattern. Non-adhering stones of the first characteristic are removed; the mask is removed exposing a pattern on the structural surface of said adhesive coating. Stones of a second characteristic are applied to the surface and adhere to the exposed adhesive coating. Excess, non-adhering stones are removed leaving a patterned stony surface, which is then covered with a thin layer of clear plastic material.
