Floor Muffler LVT Ultraseal Underlayment
It isn’t call ultraseal for no reason! This underlayment not only protects your floor from moisture, but it also makes your flooring quieter. This is a perfect product for silencing your vinyl or LVT floor! It can also be installed on top of concrete, OSB and wood subfloors.

Start the Installation
Step 1: Read Instructions!
Read the detailed Floor Muffler LVT UltraSeal Underlayment Installation information before you install. Reading the manufacturer’s instructions for a proper installation will ensure your warranty will not be voided and your floors will last for years.
Step 2: Prepare, Inspect, and Clean Subfloor
Follow these directions to properly prepare, inspect and clean both wood and concrete subfloors. This must be done prior to starting the underlayment installation. Make sure the subfloor is structurally sound, level and is free of dust and debris. The deflection cannot exceed L/360 of the span under intended live and dead loads. Check for protruding nails and/or defects in the subfloor. If installing over concrete, the concrete must be dry with moisture emission rates that do not exceed 3lbs. per 1000 square feet per 24 hours as measured by the Anhydrous Calcium Chloride Test.
Step 3: Begin Installation
Start in a corner with tape strip side next to wall and overlapping film toward the open room. Install the FloorMuffler® LVT UltraSeal (film side down) parallel to the wall in the opposite direction as you plan to install the flooring planks. When installing the FloorMuffler LVT UltraSeal, leave at least 2” going up the wall.
Step 4: Unfold
Be sure to unfold the film, extending it 3” from the foam.
Step 5: Roll Out
Roll out the next roll of FloorMuffler® LVT UltraSeal in the same manner, making sure that the foam seams are butted together. Be sure to overlap only the moisture barrier lip and not the foam pad.
Step 6: Stick and Repeat
Remove the adhesive liner and adhere the foam to the film overlap. Repeat until you are complete!
