System and method for manufacturing architectural blocks with stone-like appearance

Abstract

Apparatus, systems, and methods for applying plaster compositions to block substrates to yield a product having the appearance of cut stone. An example apparatus includes: a manifold; a mold connected to the manifold with a channel to receive the block substrate; a delivery hose connected to a top of the manifold to deliver plaster composition to the manifold for application to the block substrate; a pressure release hose connected to the manifold; and a vibrating mechanism connected to the mold. A system further includes a conveyor that moves block substrates through the mold. An example method includes: wetting a surface of a block substrate; moving the block substrate through an application apparatus as described, applying a layer of plaster composition to a surface of the block substrate, vibrating the mold and block substrate during application of the plaster composition, and allowing the plaster composition to harden.
