Common use of Surface finishes Clause in Contracts

Surface finishes. After removal of shuttering, unless instructed to the contrary, the face of exposed concrete is to be rubbed down immediately to remove fins or other irregularities. In the events of parts of the concrete being honeycombed, such portions are to be cut to a depth and shape required by the Architect and made up with fine concrete of equal quality in such a manner as shall be directed. The faces of concrete for which shuttering is not provided, other than slabs are to be smoothed with a wooden float to give a finish equal to that of the rubbed- down surface where shuttering is provided. The top face of a slab which it is not intended to cover with other materials is to be leveled and floated before setting to a smooth finish at the levels or falls shown on the drawings or elsewhere. The floating must be carried out in a way as will prevent an excess of mortar being brought to the surface of the concrete. The top of a slab intended to be surfaced with mortar, granolithic, or similar materials is to be brushed with a stiff broom while still green to remove any laitance and to provide a roughened surface.
