Common use of FINISHING UNFORMED SURFACE Clause in Contracts

FINISHING UNFORMED SURFACE. Unformed surface shall be finished by one or more of the operations of screening, floating and trowelling. Working of the surfaces should be done at proper time employing experienced men and should be just sufficient to produce the desired finish. Screeding which gives the surface its approximate shape by striking off surplus concrete immediately after compaction shall be accomplished by moving a straight edge or template with a sawing motion across wood on metal strip that have been established as guides. Where the surface is curved, a special screed should be used. Softly after the concrete is screed the surface should be brought true to form and grade by working in sparingly with wooden float. If a coarse textured finished is desired or if the surface is to be steel troweled, a second or final floating should be performed after some stiffening has occurred and the surface moisture film or shine has disappeared. Where a smooth dense finish is desired, floating shall has disappeared from the floated surface and when the concrete has hardened sufficiently to prevent fine materials and water from being worked out to the surface. Excessive trowelling particularly at an early time shall be avoided.
