          A.Grout joints in accordance with manufacturer's instructions and ANSI A108.10.
 
          B.Clean sanding water, dust, and foreign substances from joints to be grouted.
 
          C.Clean and dry tile surfaces.
 
          D.After grouting, remove all grout residue promptly.
 
          3.4PROTECTION
          ** NOTE TO SPECIFIER ** The following are general recommendations for protection during construction. Specific applications and products may allow tiled areas to be occupied sooner.
 
          A.Floors: Protect from all traffic for at least 72 hours after installation.
          1.Do not step on floor for at least 24 hours; if traffic is unavoidable after that, use plywood stepping boards.
          2.Protect from heavy traffic for at least 7 days after installation.
          3.When fast-setting materials are used to allow faster occupancy, comply with the manufacturer's recommendations.
 
          B.Walls: Protect from impact, vibration and heavy hammering on adjacent and opposite walls for at least 14 days after installation, unless manufacturer's instructions allow a shorter period.
 
          C.Protect from food products and chemicals which can cause staining for at least 14 days.
          ** NOTE TO SPECIFIER ** When dealing with cement-based products, it should be noted that temperature and humidity during and after installation of tile affect final curing time. That is, low temperatures -- 60 deg F (15 deg C) and under -- and high humidity -- 70 percent and above -- will delay final cure time.
 
          D.Protect from freezing and total water immersion for at least 21 days after installation.
