What Underlay is Required For Installing Vinyl on a Concrete Floor

So you’ve just purchased your new vinyl floor to replace your old, worn-out floor. With vinyl, you don’t typically need to install underlayment as it comes with a built-in cushioning effect and can conform to the surface underneath. 

However, instances such as installing vinyl over concrete require special circumstances. Concrete under vinyl can cause several issues, such as mould and mildew growth, warping, and poor insulation.

Stick with Mersey Flooring to explore the best underlayment options for your concrete floor.

The Importance of Correct Underlay

Underlay may seem like an unimportant part of floor installation. However, it has many benefits, providing a high-quality and durable installation for your home.

As previously mentioned, underlay protects your home from moisture build-up, preventing mould and mildew for a healthier home environment. This is especially important for those with respiratory issues. 

Underlay also provides a smooth, even surface for an appealing look, minimising the risk of damage and wear and tear. This protective layer will enhance heat insulation when the months get colder, reducing your bills. 

For those who live in a noisy environment or for buildings which require low-level disruption, underlay can prevent noise pollution and enhance comfort.

The Types of Underlay Suitable for Vinyl Flooring

1. Foam Underlay

Foam underlay is a popular choice for underlay due to its versatility, cushioning effect, and cost-effectiveness. 

If you’re looking for a comfortable underfoot experience, then this is the option for you. With thermal insulation and sound absorption, you gain all the benefits for a low cost!

Ensure that foam underlay is suitable for use with the specific type of vinyl flooring, as excessive cushioning can damage locking mechanisms.

2. Rubber Underlay

Durable and dense rubber underlay is typically used for installing vinyl flooring over concrete. 

Made from natural or synthetic rubber, this option provides robust support and stability for your home, creating a floor you can enjoy for years to come. It can withstand heavy traffic, and similar to foam, it has great sound and thermal insulation. 

However, this may be a more expensive option for those on a budget.

3. Cork Underlay

Cork is an eco-friendly, natural option available in various thicknesses for many installation needs. 

This is a great choice for moisture-prone areas, such as kitchens and bathrooms, with natural resistance to mould and mildew. The natural sponge effect of cork makes for a comfortable floor. 

Similar to the previous options, its sound and thermal insulation make it a great choice for noisy environments. 

4. Plywood Underlay

Plywood creates a smooth, stable surface for your floors, perfect for an elegant and appealing finish. 

This is great for levelling uneven concrete subfloors for seamless vinyl installation. Its thin layers of wood veneer provide a durable surface, minimising damage from wear and tear with its high impact resistance. 

This can be used with various vinyl flooring, such as sheet, plank, and tile. 

5. Vinyl-Backed Underlay

This type of underlay is specifically designed for vinyl flooring.

Its smooth surface provides a stable foundation for vinyl flooring to ensure longevity and durability. This helps to maintain the integrity of vinyl plank and tile locking systems. 

Its moisture and sound resistance make it perfect for areas such as bathrooms and kitchens and for buildings which require minimal noise disruption. With an easy peel-and-stick system and loose-laid installation, this is a simple option for DIY projects. 

6. Moisture Barrier Underlay

Moisture barrier underlay is designed to prevent moisture emanating from the subfloor, protecting it from warping, adhesive failure, and mildew.

This is a popular choice for basements and ground-level buildings. With this option, you will have a healthier home, preventing pores from permeating the floor and causing health issues as a result. 

With this underlay, your vinyl floor will look fresh and new years later, reducing the need for repairs and replacements.
