Abstract
A block of high density expanded polystyrene is cut into a preselected ornamental shape and one or two layers of a cementitious material are sprayed onto the block to produce a durable article of manufacture having utility as a structural element in the construction industry. Each layer of the cementitious material is about .015 inch thick so that detailed ornamental features are not filled in. The cutting and spraying are accomplished in a factory remote from the job site so that the construction crew at the job site need only attach the finished product to the building when it is delivered to the job site.
