strength, durability and moisture protection up to 4 lbs. of
pressure. In geographic areas where concrete subfloors are
subject to excessive moisture, a calcium chloride moisture test
is required. Vapor emission readings in excess of 4 lbs. per
1,000 square feet in 24 hrs. will require additional protection
such as concrete sealant or polyethylene sheeting.

HVAC operating)
• ¾" interior plywood, OSB flooring, gypcrete (must be primed
before glue down)
• Waterproofing and crack-isolation membranes
• Cement backer units
• Existing vinyl, wood, and laminate floors
FLOOR PREPARATION
• Subfloor should be clean and dry
• Follow the wood manufacturer’s installation instructions for any
additional preparation
QUICK AND EASY INSTALLATION
Requires no additional seaming tape, cuts with a knife.
1. Install Eco-Ultimate Silencer™ Acoustical with film down against
concrete/subfloor.
2. For floating and nail down installations, roll out underlayment
with tape strip next to wall. Roll out next row in same manner
butting underlayment close to first row (do not overlap) and
covering the moisture barrier film. Remove the tape strip and
secure the overlapping moisture barrier film.
3. For double glue down installation for wood flooring, use a
urethane based adhesive (based on the adhesive manufacturer’s
recommendation) with a 1/16" – 3/32” trowel on the subfloor.
Trim off the excess overlapping film. Roll out underlayment
with tape strip next to wall. Roll out next row in same manner
butting underlayment close to first row (do not overlap). Roll with
a 75 -100 lb. roller to smooth out any air pockets and to secure
a good bond to the adhesive.
4. Install flooring according to the laminate/wood manufacturer’s
installation instructions.
