Healthier Choice OMNICHOICE Acoustical Underlayment - Manual

Installation Instructions
OMNICHOICE VAPOR BLOC TM is a high density polyurethane acoustical underlayment designed to reduce in-room noise and floor-through-ceiling
sound transmission in multi-level construction. The floor coverings listed below are commonly installed over OMNICHOICE VAPOR BLOC. For
underlayment installation instructions, first select the floor covering to be installed and the installation method to be used.
Site Conditions and Floor Preparation
First, follow the floor covering manufacturer’s site conditions and floor preparation instructions. Prior to the installation of OMNICHOICE VAPOR
BLOC, the sub-floor must be clean and dry. When installing OMNICHOICE VAPOR BLOC on a concrete sub-floor, the moisture emission rate may not
exceed 10 lbs. / 1,000 sq. ft. / 24 hrs. per the anhydrous calcium chloride test (ASTM F1869). If moisture emissions exceed this level an additional
moisture or vapor barrier may be required, check the floor covering manufacturer’s guidelines.
ACCLIMATE OMNICHOICE VAPOR BLOC FOR A MINIMUM OF 24 HRS. PRIOR TO INSTALLATION.THE HVAC SYSTEM MUST BE
OPERATIONAL AND THE INSTALLATION SITE MUST BE HEATED TO A MINIMUM OF 65°F FOR AT LEAST 72 HOURS PRIOR TO THE
INSTALLATION. RELATIVE HUMIDITY MAY NOT EXCEED 65%.
Floating Installation
1. Roll out OMNICHOICE VAPOR BLOC underlayment parallel to the wall and perpendicular to the direction the floor covering will be installed. Avoid
placing a floor covering seam directly over an underlayment seam.
2. Use a utility knife to trim the underlayment to fit the sub-floor leaving no gaps.
3. Install the next section of underlayment in the same manner making sure the seams are butted together but not overlapping. Repeat until
the entire installation area is covered.
4. The seams may be taped to hold the underlayment in place during installation.
5. Install the floor covering according to the manufacturer’s installation instructions.
