No pipe cutting machine shall be used on the finish floor slab. <br /> <br />4. Steel shall not be placed on the finish slab to avoid rust staining. <br /> <br />5. Acids should not come in contact with slab. Do not charge battery powered <br />equipment on floor areas to be polished. <br /> <br />6. All painters will use drop cloths on the concrete.
