Q&A: Everything you want to know about vinyl flooring underlays

The underlay for vinyl planks is one of the most important and at the same time most underestimated elements of the entire floor. In practice, it largely determines the durability, stability and comfort of use of the floor. An incorrectly selected primer may lead to damage to the locks, deformations and even loss of the warranty.

In this article, we answer the most important questions and explain how to choose the right solution for vinyl panels.

Q&A: Everything you want to know about underlays for vinyl planks

Why is the underlay for vinyl planks so important?

Vinyl panels (LVT/SPC) differ significantly from laminated panels. They are thinner, more precise and have delicate latching systems that require a stable, hard and resistant base.

A good foundation performs several key functions:

  • stabilizes the entire floor structure
  • evens out micro-unevenness of the substrate
  • muffles the sounds of footsteps
  • increases comfort of use
  • protects the lock system against overload

Can I use regular underlayment for vinyl planks?

NO.

This is one of the most common mistakes when installing vinyl panels.

Ordinary foam underlays (intended for laminate) are too soft and elastic. In the case of vinyl, they act like a “trampoline” – they cause the floor to deflect with each step.

Effect?

  • panel micro-movements
  • lock overloads
  • cracking or loosening of joints
  • shortening the life of the floor

Vinyl planks require stability, not flexibility.

What underlay is suitable for vinyl planks?

Only high-density and low-deformability underlays are used for vinyl, such as:

  • PUM underlays (polyurethane-mineral)
  • quartz foundations
  • specialized underlays dedicated to SPC/LVT
  • underlays integrated with panels

Their key feature is stiffness combined with minimal compression – so that the floor works as a uniform surface.

Does thicker foundation mean better?

Not always.

In the case of vinyl planks, thickness is not the most important thing. The key are:

  • material density
  • compression resistance
  • dimensional stability

Too soft, even a thick underlay may be worse than a thin but professional systemic vinyl underlay.

What underlays does Pacific Vinyl Floors use?

At Pacific Vinyl Floors, we focus on solutions tailored to vinyl technology.

Our collections:

they have integrated Silent Step soundproofing underlay (1 mm) in technology IXPE.

This solution provides:

  • stabilization of the entire structure
  • noise reduction
  • walking comfort
  • faster and safer installation

We also offer a collection:

These are vinyl panels without a built-in underlay, which require the use of a dedicated external underlay, adapted to the installation system and type of substrate.

What happens if I use the wrong foundation?

The consequences of incorrect selection of foundation can be serious:

  • damage to click locks
  • formation of gaps between panels
  • floor creaking
  • lack of stability when walking
  • loss of manufacturer’s warranty

Therefore, the selection of the underlay is as important as the selection of the panels themselves.

Summary

The underlay for vinyl planks is not an addition, but the foundation of the entire floor. It requires a technological approach and adaptation to the specificity of the material.

The most important rules:

  • do not use underlays on laminate
  • choose high-density underlays
  • pay attention to stability, not softness
  • use system solutions (e.g. IXPE Silent Step)

At Pacific Vinyl Floors, we design our collections for maximum durability and comfort – from the panel core to the underlayment.
