The foundation of any great flooring installation is not seen at a glance; it lies beneath the surface in the form of the subfloor. This critical component not only supports the visible flooring but also significantly impacts the functionality and longevity of the floor’s surface. As such, choosing the best subfloor material is vital for ensuring that your flooring can withstand the rigors of daily use while maintaining its aesthetic appeal. In this blog, we’ll dive into the essential considerations for selecting materials and steps for subfloor leveling that align with your specific flooring requirements.

 

Why the Right Subfloor Material Matters:

The choice of subfloor material is crucial for the successful installation and long-term performance of any finished flooring. The subfloor serves as the foundation that supports the weight and wear of the floor, so it must be strong, stable, and compatible with the specific flooring type. Using the wrong subfloor can lead to a variety of issues, such as squeaky, uneven, or damaged floors, as well as potential safety hazards. Factors like moisture resistance, dimensional stability, and fastener-holding ability are all important considerations when selecting a subfloor. 

 

Working with a professional to ensure the best subfloor material is chosen and properly installed can help prevent costly problems down the line and ensure the finished floor looks and performs its best for years to come.

 

Best Subfloor Material for Various Projects

The best subfloor material for your project depends on several factors including the type of top flooring, the level of moisture exposure, and your budget. Here are some top contenders:

Plywood:

Renowned for its strength and durability, plywood is one of the best subfloor materials for residential projects where moisture is not a major concern. It’s ideal under hardwood, laminate, and carpet.

Plywood is best used for:

  • Hardwood: Plywood provides a stable and sturdy base that helps prevent the warping and flexing of hardwood planks.
  • Laminate: The smooth surface of plywood is ideal for laminate, which requires a flat substrate to avoid bending and cracking.
  • Carpet: Plywood offers a firm support structure beneath carpet, ensuring even wear and longevity.
  • Vinyl: While not as moisture-resistant as concrete or cement board, plywood can support vinyl installations in dry areas with proper moisture barriers in place.

 

Oriented Strand Board (OSB):

Cost-effective and strong, OSB is made from compressed wood strands and adhesives. It’s become increasingly popular for both commercial and residential buildings under laminate and engineered wood floors.

OBS is best suited for:

  • Engineered Wood: OSB’s dimensional stability and strength make it suitable for engineered wood flooring, which tends to expand and contract less than solid hardwood.
  • Laminate: The uniform and consistent nature of OSB provides a good base for laminate floors.
  • Carpet: Like plywood, OSB offers a solid foundation for carpet, helping to extend its life and maintain its appearance.
  • Vinyl Plank: OSB can also be used under luxury vinyl plank flooring, particularly in residential settings where heavy moisture is not a concern.

 

Concrete:

For projects where moisture might be a concern, such as basements or ground floors, concrete subfloors are ideal. Concrete is durable and offers excellent support for vinyl, ceramic tile, or stone.

Concrete is best suited for:

  • Ceramic and Porcelain Tile: Concrete’s hardness and stability make it an ideal subfloor for tile installations, which require a mortar bed.
  • Vinyl Tiles and Sheets: Concrete subfloors provide a smooth, durable base for vinyl tiles and sheet goods, especially in commercial environments.
  • Stone: Natural stone flooring benefits from the solidity of concrete, minimizing the risk of cracks or movement.
  • Epoxy Coatings: Epoxy floor coatings work well over concrete, often used in garages and industrial settings.

 

Cement Board:

Often used as a subfloor material for tile installations, cement boards provide a stable, water-resistant base that helps protect the floor against moisture.

Cement board is best suited for:

  • Ceramic and Porcelain Tile: Cement board is specifically designed to be a moisture-resistant substrate for tile in high-moisture areas like bathrooms and kitchens.
  • Stone Tile: Stone tiles also benefit from the stability and moisture resistance of cement board, ensuring a long-lasting installation.

 

Particle Board: 

This is an economical choice suitable for light-duty applications in dry areas. It is often used under carpet or laminate flooring in residential settings.

Particle board is best suited for:

  • Carpet: The smooth surface of particle board is suitable under carpet, where high impact resistance is not required.
  • Laminate: Suitable for use under laminate in strictly dry areas, provided that the area remains free of moisture.

 

For specialized applications, materials like magnesium oxide (MgO) boards are emerging as eco-friendly subfloor alternatives to concrete, drywall, and other building materials. The choice of subfloor material should be based on factors such as the type of finished flooring, expected foot traffic, moisture levels, and budget. Working with a professional can help ensure the right subfloor is selected and properly installed for a successful flooring project.

 

Subfloor Leveling: Ensuring a Flat Base for Flooring

Leveling a subfloor is a critical step in preparing for a new flooring installation. An uneven subfloor can lead to flooring damage, such as cracks in tile or gaps in wood planks. Here’s how to achieve a well-leveled subfloor:

  1. Assess the Level and Condition: Begin by checking the subfloor with a long level. Identify low spots or bumps that may need attention.
  2. Use Leveling Compounds for Minor Adjustments: For concrete subfloors, a self-leveling compound can be poured over the existing floor to fill in the dips and create a smooth, level surface. For wood subfloors, shims can be used under the subfloor material to even out small inconsistencies.
  3. Replace Damaged Sections: If significant damage or warping is found, replacing sections of the subfloor may be necessary. This will provide a solid, stable base for any flooring.
  4. Sand High Spots: If you’re dealing with a wood subfloor, use a sander to reduce high spots. This method is simple and effective for minor adjustments.
