EZ-Floor Foam Underlayment Instructions Jobsite Conditions
  • The room, underlayment, flooring materials and adhesives must be maintained at 65 to 85 degrees F and the relative humidity below 60% for 48 hours prior to, during and after the installation.
Subfloor Preparation
  • All subfloor work should be structurally sound, clean and level. The moisture content of the subfloor should not be more than 10 lbs. Per 1000 s/f 24rs as measured via a Calcium Chloride test, before the underlayment is applied.
  • EZ-Floor LVT underlayment must be installed perpendicular to the length of the plank being installed and the moisture barrier must be facing down towards the subfloor.
  • Determine the layout, noting that the seams of the underlay are at least 4” away form the seams of the material being installed.
  • Cut the underlayment to the desired length and position it in the space to be covered.
  • A 1/4” space needs to be maintained between the material and any walls or fixed objects for expansion and contraction.
  • Cut the second sheet of underlay to length and position it with seam butted tightly to the first sheet.
  • Secure the sheets with tape.
  • Proceed to cover the entire room, making sure the sheets are tightly butted together, without gaps.
Note: Gaps in the underlayment may “telegraph” through some resilient floors, so the underlayment should be installed as smoothly and as well seamed as possible.

Foam Underlayment

  • Why foam underlayment?

EZ-Floor foam underlayment is a wonderfully affordable underlay product that provides some sound dampening qualities. This inexpensive solution can be used underneath any floor surface, but may not be idea in situations where you need to add a lot of height, as you are limited on options for thickness. Foam underlay provides excellent moisture protection, is mold and mildew resistant, and is easy to install, however, may not provide the ideal sound resistance compared to other underlay types.

Do I REALLY need underlay?

  • Yes, most definitely.

Underlayment is an amazing invention created by the flooring gods out of necessity. Underlay has an impressive list of benefits, including: adding warmth to your floors so your feet aren’t so cold on new tile flooring, adding comfort and a slight ‘give’ underneath wood or vinyl floors, reduced sound transmission (great for houses with noisy teenagers!), as well as reducing in room step noise. The image to the left is a very simplified example of using underlayment versus not using it, but as you can see the benefits greatly outweigh any reason not to.

Making your house a home

  • Products that work together

Foam underlays are incredibly versatile, since they do not contain any materials that could leak and stain a flooring surface. Foam is the perfect underlay option for virtually any floor, including underneath laminates, vinyl, engineered wood, cork, and bamboo. For tile flooring, a different type of underlayment is typically recommended.


  • What does it mean?

Foam underlayments are typically around 2mm or 3 mm thick. If adding height to your floor is important to your installation, we recommend choosing another product type such as rubber or cork, which come in substantially thicker options for your needs.

IIC / STC Ratings

  • What do they mean?

IIC stands for Impact Insulation Class, which refers to impact sounds such as shoes hitting the ground, dropping a cell phone, or other scenarios where something it dropped or impacts the floor. STC stands for Sound Transmission Class, which refers to any audible noise (not an impact) such as music playing aloud, a conversation, or a loud television, for example. With both of these ratings systems, the higher the number rating is for the underlayment, the better it will suppress sound, and the quieter a room will be. You may want to pay close attention to these ratings when shopping for underlayment if sound reduction is important to you.

Underlayment + Moisture Barrier + Improved Sound Reduction

  • The ultimate option in underlayment

3-in-1 underlayment product really are the best of the best. Not only do they save you time and money on not having to put down yet another product during installation, but they also have improved added sound reduction properties. This product may meet the quality level required by a professional, but it also works wonders in DIY-er or Weekend Warrior home installations as well.

charles b wengreen
We absolutely recommend underlayment for use with vinyl planks that do not already have underlayment attached to them. Be sure to check the manufacturer product specs and PDFs to make sure the use of underlay wouldn't void your warranty.
