and brush attachment shall be used. All surface litter such as paper clips, bits of paper, <br />and staples shall be hand-picked from the carpeting and placed in a trash receptacle. <br />Vacuuming must be done in a slow movement for a more thorough pickup. After the <br />carpeted floor has been vacuumed, it shall be free of all visible litter, soil and embedded <br />grit. <br /> <br />G. Spot Carpet <br /> <br />Use a damp cloth or sponge and regular carpet shampoo material. Do not wet the spot <br />itself heavily and rub it back and forth across into the clean area of the carpet; rather, <br />start with a cloth or sponge which is only moderately wet and rub it with a brushing action <br />from the edge of the spot towards the center, so that the size of the spot is reduced rather <br />than spread. <br /> <br />H. Furniture and Equipment Replaced <br /> <br />All furniture and equipment moved during the cleaning operation will be returned to its <br />original position. Portable and tank-type machines will be wiped clean, dust bags <br />emptied, and vacuum hose coiled loosely on machine or hung on racks provided for that <br />purpose. Equipment in view will always appear neat and orderly. <br /> <br />3.5.1 STRIPPING AND REFINISHING RESILIENT TILE FLOORS <br /> <br />A. Stripping <br /> <br />Stripping will be defined as the complete removal, without damage to the floor surface, of all <br />finish and/or sealer from all visible floor surfaces and from those floor surfaces that can be <br />exposed by the removal of non-fixed furnishings. Stripping should also include the complete <br />removal of all marks, scuffs, and stains, etc. except in cases in which there is damage to the <br />floor surface. <br /> <br />The stripping chemical(s) used should meet the specifications given in these bid documents <br />for the type of finish and/or sealer being stripped, and should be used according to the <br />manufacturer’s directions. <br /> <br />The floors should be scrubbed with a single-disc floor machine equipped with a stripping pad, <br />except those areas in which the use of manual scrubbing devices are necessary to completely <br />remove the finish and/or sealer (along walls, in corners, etc.). The stripping solution and rinse <br />water should be picked up with a wet/dry vacuum except in areas where its use is impossible <br />or impractical (very small areas, areas with low amperage circuits, etc.). <br /> <br />All floor surfaces to which stripper has been applied should be thoroughly rinsed with clean <br />water. When a wet/dry vacuum is used, the area should be rinsed at least once after the <br />stripping solution has been removed. If a mop is used to pick up the stripping solution, the <br />area should be rinsed at least twice. <br /> <br />B. Refinishing <br /> <br />
