Abstract In the cladding, that is coating or lining, a structural surface with a cementitious compound, for example a refractory concrete, there is disposed adjacent said surface a mould open onto said surface and the cementitious compound is filled into said mold while the mould is vibrated to compact said compound. The surface to be clad preferably has secured thereto to project forwardly therefrom nonlinear ties adapted to key into the cladding and the mould is made up of vertical guide members releasably secured to said surface and guiding for upwards displacement parallel to said surface a shutter plate making up with said guide members said mould open onto said surface, the shutter plate being raised, if necessary with mechanical assistance, while the cementitious compound is being filled into said mould and said shutter plate is being vibrated to compact said compound. The apparatus is dismounted from said structural surface, and remounted at another portion of said surface and utilized to form blocks of cementitious material bonded to said surface at small intervals apart in the horizontal direction.
