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.

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:
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?
Vinyl planks require stability, not flexibility.
Only high-density and low-deformability underlays are used for vinyl, such as:
Their key feature is stiffness combined with minimal compression – so that the floor works as a uniform surface.
Not always.
In the case of vinyl planks, thickness is not the most important thing. The key are:
Too soft, even a thick underlay may be worse than a thin but professional systemic vinyl underlay.

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:
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.
The consequences of incorrect selection of foundation can be serious:
Therefore, the selection of the underlay is as important as the selection of the panels themselves.
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:
At Pacific Vinyl Floors, we design our collections for maximum durability and comfort – from the panel core to the underlayment.
