The surface must be structurally sound, clean, dry, and free from dirt, oil sealers, or any contaminants that would prevent a good bond. QuietFloor must acclimatize in its sealed packaging for 48 hours at a temperature of 65 degrees.
Inspect the concrete subfloor for any open cracks and fill with a high-grade patch. Remove any excess concrete lumps or residue that may interfere with the installation of QuiteFloor. The concrete slab should be fully cured, dry, smooth, flat, and accept water penetration. Concrete must be free of efflorescence and not subject to hydrostatic pressure. A good quality concrete waterproof sealer may be required if moisture in the slab is above 10%.
Gypsum substrates must have a PSI greater than 2000 and must be first primed or sealed per the manufacturer’s instructions.
The subfloor should be permanently dry, smooth, flat, and clean free from dirt, grease, wax, paint, oil, or anything that would hinder a good bond. Plywood subflooring should be of a good grade. Variations in floor level over 1/8″ within a 3-foot span should be leveled before installing underlayment. Any nails or other protrusions should be pounded flat or removed. The subfloor should have L360 for deflection.
Set the Installation Instructions Installation Instructions Quietfloor into the adhesive while it is still wet. Do not allow the adhesive to skin over. Lift a corner periodically to see if the adhesive is transferring 100%. If adhesive is not transferring, apply additional adhesive. Flat trowel the QuiteFloor to smooth out air pockets.
Continue to install QuiteFloor sheets making sure to install with edges butted tight to each other, and do not overlap seams. After the first row is completed, roll the mat with a 35 lb roller. Install the second row with staggered seams to the first row and repeat the steps above. It is recommended to wait 8-12 hours before installing tile on top of QuiteFloor.
Installation of Tile, Stone, or Marble
Before installation of the flooring, install QuiteFloor perimeter isolation strips with PSA backer or cut 1″ wide by 4′ lengths off the sheet. Fasten the perimeter strips to the wall of the entire subfloor using T-700 or mastic cutting strips. Make sure to follow applicable ANSI A.108/A.118/A.136 for proper installation of ceramic tile. When applying tiles to QuiteFloor always use a polymer-modified mortar meeting ANSI A118.4 or A118.11 standard. It is recommended to key-in/burn in a thin layer of thin set into the surface of QuiteFloor as the first step to tiling.
After the finished floor is installed and grouted, trim the excess perimeter isolation strip flush with the floor. Prior to installation of cove or base molding seal isolation foam with either Sound Seal acoustic caulk or any waterproof acrylic caulk. Adhere the base or cove to the wall. The base board must not touch the floor to avoid sound/vibration to flank through the walls.
