Tranquility Ultra Flooring Underlayment Facts & Installation
TRANQUILITY VINYL PLANK UNDERLAYMENT
ADVANTAGES
- TRANQUILITY TM Ultra Underlayment is made with high-density polyurethane foam using rapidly renewable resources (soybean polyols and vegetable oils).
- Suitable for floating, glue down, LVT and vinyl plank flooring, as well as radiant heat flooring systems.
- New revolutionary moisture barrier film for the best bond strength, durability and moisture protection up to 7 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 7 lbs. per 1,000 square feet in 24 hrs. will require additional protection such as concrete sealant or polyethylene sheeting.
- Contains Ultra-Fresh®, an antimicrobial protection that resists mold and mildew.
- CrushprufTM technology resists indentation that enables your floors to perform to its fullest potential and last a lifetime.
- Eliminates minor subfloor imperfections.
- Offers the industry's best limited lifetime warranty.
- This product exceeds ASTM test for compression strength required for some vinyl plank manufacturers.
APPROVED SUBSTRATES
- Dry, completely cured concrete (at least 14 days old with 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, dry and level
- Follow the manufacturer's installation instructions for any additional preparation

UNDERLAYMENT APPLICATIONS
Floating | (approved sizes) |
Residential: | click vinyl 3mm and greater |
Commercial: | click vinyl 4mm and greater |
- For floating floors, install with film UP. For glue down floors, install with film DOWN.
- Floating installations, roll out underlayment next to wall. Roll out next row in same manner butting underlayment close to first row (do not overlap). Seal the seams with a moisture resistant tape. Install LVT/vinyl plank per manufacturer's instructions.
- Residential glue down installations, same as above, then apply adhesive to the top side of the underlayment per LVT/vinyl plank manufacturer's instructions. Double glue down is optional.
- Commercial glue down installations: Underlayment must first be bonded to the subfloor with adhesive, preventing any movement on the floor. Double glue down is required.
- Double glue installations, use SILENCER QUICKLAY spray adhesive or other pressure-sensitive trowel adhesives (based on the adhesive manufacturer's requirement) using a 1/16" trowel on the subfloor. Roll out underlayment 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. Then apply adhesive to the top side of the underlayment per LVT/vinyl plank manufacturer's instructions. After flooring is installed, roll with a 75-100 lb. roller to secure a good bond to the adhesive.
- Install flooring according to the vinyl manufacturer's installation instructions.
