1. A method of manufacturing a lightweight block adapted to give the appearance of natural or cut stone, comprising:
providing a lightweight block substrate having a density of less than 1680 kg/m3;
moving the lightweight block substrate on a conveyor under an applicator chute containing a aesthetic coating composition;
the applicator chute applying the aesthetic coating composition to a surface of the lightweight block substrate to form an aesthetic coating layer;
moving the lightweight block substrate with the aesthetic coating layer on the conveyor under a leveler which levels the aesthetic coating layer and removes excess aesthetic coating composition from an outer surface of the aesthetic coating layer; and
allowing the aesthetic coating layer to harden to form a hardened aesthetic coating layer,
the aesthetic coating layer being formulated to resemble natural or cut stone when applied to the surface of the lightweight block substrate and allowed to harden and form the hardened aesthetic coating layer.
