FLOORING WITH UNDERLAYMENT INSTALLATION

SURFACE PREPARATION
NOTE: All concrete floors must be structurally sound, dry, stable and meet the acceptability
requirements of the ASTM F710 standards. In addition to these standards follow the floor
preparation steps on page 2.
*
APPLYING UNDERLAYMENT
NOTE: Use blank connector fillers to protect electrical connections.
NOTE: Do not use OSB product for underlayment as it will swell when wet and ruin
the installation. Use only approved flooring grade underlayment material that has a
thickness of 7/32" (5 mm). Make sure to offset seams in underlayment sheets.
Actual thickness must be between 0.186 and 0.205 inches.
• Ensure that all track components are secured to the floor and carpet ramps have been
removed. Measure and cut underlayment panels to fit required spaces and provide a
1/8" (3.2 mm) gap around the perimeter of the outer wall of trim rings, at track junctions.
TIP: Use trim rings or provided carpet templates to assist plotting radius cuts in
underlayment at Thread junction points.
*
• Apply all underlayment to Thread layout and secure to building floor surface per any
applicable local codes or specifications.
