A method for manufacturing a coated masonry product comprising a body part coated with a coating material, the method comprises: providing a said body part and a quantity of said coating material in liquid form for coating said body part; providing a mould part presenting a moulding surface; applying to the moulding surface a retardant material adapted to retard the curing of said coating material; placing the coating material and the body part within the mould part such that the coating material is simultaneously in contact with the moulding surface and a surface of the body part; curing those parts of the coating material in contact with the body part; separating the moulding surface from the coating material thereby to expose a surface of the coating material which remains uncured by action of the retardant. The core is preferably polystyrene; the coating preferably a cementitious composition. Also claimed is a moulding apparatus suitable for the above method comprises: a sleeve assembly defining an elongated channel having a substantially uniform cross-sectional moulding profile along its elongate length and comprising a concavity defining said moulding profile for receiving said body to be coated therein with masonry-effect coating material; wherein the sleeve assembly comprises an outer sleeve part and an inner sleeve part removeably insertable into the outer sleeve part for support thereby, wherein the inner sleeve part includes a floor portion bounded at two opposite edges thereof by opposing wall portions which collectively define between them said elongated channel. The walls are preferably made from flexible material to aid removal of the mould.
