          PART 3EXECUTION
 
          3.1EXAMINATION
 
          A.Site Verification of Conditions:
          1.Building must be fully enclosed including doors, windows and roof.
          2.Interior ambient temperature must be 50 degrees F (10 degrees C) and rising at least one day before installation and maintained at minimum of 50 degrees F (10 degrees C) temperature for a minimum of 5 to 7 days until gypsum underlayment is dry.
          3.Subfloor to have a deflection that does not exceed L/360 or tighter tolerance as per finished flooring system requirements.
          4.Subfloor must be broom swept with all excess wallboard mud removed, and all holes patched.
          5.Wood construction must be with tongue and groove subfloor (OSB or plywood).
          6.Adequate heat and ventilation must be maintained until the moisture in the gypsum underlayment has dried to allow installation of floor covering.
          7.For installation on concrete substrates the subfloor must be fully cured (typically 28 days). Moisture tests should be performed to ensure proper hydration using ASTM F1869 to ensure MVE level is less than 3 lbs (1.4 kg). per 1000 sq ft (92.9 sq m).
          8.For on grade, below grade or applications over a crawl space, vapor barriers must be applied.
 
          3.2REQUIREMENTS
 
          A.Surface Preparation:
          1.Subfloor must be properly primed.
          2.Use Keene Building Products' GSL PRIMER on all surfaces to receive gypsum. underlayment.
          3.All supporting surfaces shall be dry, structurally sound, solid, free of movement and well bonded, and free of dust, oil, grease, tar, or other contaminants that may act as bond breakers.
 
          B.Priming:
          1.Dilute GSL PRIMER before application. Dilute 1-part GSL PRIMER concentrate to 4-parts potable water (1: 4).
          2.Using a long handle roller, soft bristle broom, brush, or sprayer, apply GSL PRIMER at a coverage rate of 270-320 sq ft (25.1-29.7 sq m) per gallon of primer solution.
          3.Ensure a complete and uniform coverage.
          4.Allowed to become very tacky or dry (about 1 hour).
 
          3.3INSTALLATION OF SOUND CONTROL MAT
 
          A.Preparation:
          1.Check wall bottom plate requirements prior to mobilization to job site.
          2.Review elevation changes at doorway entrance and at all interior doors, cabinetry and plumbing for transitions and differences.
          3.Ensure that the floor is clean and level.
          4.Smooth any irregularities in plywood/OSB joints by trowel application of quick setting patching compound.
          5.Patch any holes and fill any joints in the plywood or OSB with quick setting patching compound to prevent leaks.
 
          B.Quiet Qurl Sound Control Mat Installation.
          1.Quiet Qurl is laid directly over the concrete, plywood or OSB subfloor, with the black mesh/entangled net facing down and the fabric side up. The Quiet Qurl should be pushed up tightly to the wall board; the gap between the floor and wall should not exceed 0.25 inch (6.35 mm). After installation of Sound Control Mat, the Perimeter Isolation Barrier should be installed to cover gaps between sound mat and the wall (see below for complete instructions). Alternatively, the Quiet Qurl can be pushed up tightly to the Perimeter Isolation Barrier that was previously installed around the perimeter of the floor. The gap between the floor and wall should not exceed 0.25 inches (6.35 mm).
          2.Quiet Qurl entangled net core edge must be placed adjacent to other pieces without a gap. Remove plastic backing from the Zip-Strip to expose the adhesive edge along the 3 inches (10 cm) fabric overlaps. Firmly press down on the adhesive edge so that the mat remains snug to the fabric on the adjoining Quiet Qurl strip. Adjoin all seams to prevent penetration into the core material during pour. Where necessary, cover seams with tape (2 inches (50.80 mm) wide duct tape, cellophane tape or equal). Alternatively, spray adhesive such as 3M Super 77 may be used to adhere the fabric overlaps.
          3.At all doorways, use extra pieces of scrap Quiet Qurl as reinforcement by flipping the material black core up.
 
          C.Perimeter Isolation Barrier Installation.
          1.Installing Quiet Qurl Sound Control Mats prior to installing perimeter isolation barrier:
          a.Attach Quiet Qurl Perimeter Isolation Barrier with Quik Stik or equivalent to wall.
          b.Attach Quiet Qurl Perimeter Isolation or equivalent with a fast setting adhesive to wall.
          2.Installing Quiet Qurl Sound Control Mats after installing perimeter isolation barrier:
          a.Install Quiet Qurl Perimeter Isolation Barrier with Quik Stick or equivalent, or applied directly to wall with fast setting adhesive before installing the sound control mat.
          b.Seal the penetration where the perimeter isolation meets the Quiet Qurl using approved tape.
          3.Use paper wall board tape as a double lap at all corner seams and tape flat to floor and perimeter isolation per Keene Building Products details.
          4.Wrap the Perimeter Isolation Barrier material around all walls, penetrations, and pipes, including cabinetry, plumbing and electrical junctions.
          5.Provide jams as required at transitions between different areas of gypsum underlayment. Provide Perimeter Isolation Barrier at jams. Jams can be created with wood or "L" termination bar. See Keene Building Products details.
 
          3.4INSTALLATION OF GYPSUM CEMENT UNDERLAYMENT
 
          A.Mixing Proportions:
          1.General Requirements: Mix proportions and use methods in strict accordance with product manufacturer written instructions.
 
          B.Application:
          1.Pour floor topping to recommended thickness. Immediately spread and screed product to a smooth surface. Provide expansion joints in gypsum underlayment assembly where they occur in subflooring.
 
          C.Drying:
          1.Provide and maintain correct environmental conditions to keep the building clean and dry and protect against intrusion of moisture from potential sources. Provide mechanical ventilation and heat as required to remove moisture from the area until the gypsum underlayment is dry.
          2.Protection from Heavy Loads: During construction, place temporary wood planking over gypsum underlayment wherever it will be subject to heavy wheeled or concentrated loads.
 
          3.5PREPARATION FOR INSTALLATION OF GLUE DOWN FLOOR GOODS
 
          A.Sealing:
          1.Seal all areas that receive glue down floor goods with GSL All Purpose Sealer or Dependable, LLC Primer MF as per manufacturer's written instructions. Clean and seal any floor areas where the surface has been damaged before installing floor covering. Install floor covering adhesive and other components per manufacturer's requirements.
 
          B.Moisture Testing:
          1.Test gypsum underlayment to ensure it meets floor covering manufacturer's relative humidity requirements (Reference ASTM F2419).
 
          C.Finished Floor Goods:
          1.Resilient: ASTM F2419.
          2.Ceramic Tile: TCNA F180.
