Subfloor preparation is a critical step in flooring installation, providing many benefits. Proper preparation ensures the longevity, durability, and appearance of a floor finishes. Here are the key benefits you can gain from effective subfloor preparation:
Enhanced flooring durability
Subfloor preparation minimises wear and tear. A well-prepared subfloor prevents uneven pressure points that can cause premature damage to floor coverings. It also supports heavy loads, ensuring that the floor can handle furniture, appliances, and foot traffic without sagging or cracking.
Improved flooring adhesion
Subfloor preparation allows for better bonding. For materials like LVT or vinyl, a smooth and clean subfloor allows adhesives to bond better, preventing peeling or lifting. It also reduces failures as irregularities in the subfloor can lead to tile cracks or gaps over time.
Prevention of moisture issues
The subfloor acts as a moisture barrier. Addressing subfloor moisture levels prevents issues like mould growth, warping, or swelling of the flooring materials. It also increases the longevity of flooring by protecting the integrity of sensitive flooring materials.
Smooth and level surface
Preparing a subfloor increases the aesthetic appeal of a floor as it prevents visible bumps, dips, or unevenness. This ensures a polished and professional look. It also improves the ease of installation, making it easier to lay flooring materials to reduce installation time and effort.
Noise reduction
A prepared subfloor can also improve soundproofing. Proper preparation, including the use of underlayment, helps dampen sound and minimise creaks or squeaks.
Prevention of structural problems
It also helps prevent structural problems, such as stability. Fixing issues, such as loose boards or cracks in the subfloor, enhances the structural stability of flooring. It also reduces the risk of injuries due to uneven surfaces.
Cost savings in the long run
Investing in proper subfloor preparation also helps you to save in the long term. It helps prevent the need for expensive fixes due to improper installation or flooring failures. It can also extend flooring life. Proper preparation ensures the floor maintains its appearance and function for years to come.
Compliance with manufacturer warranties
Many flooring warranties require a properly prepared subfloor as a condition for coverage. Skipping this step may void warranties on materials.
Key steps in subfloor preparation:
- Inspection – identifying and addressing structural issues, such as weak spots or moisture.
- Cleaning – removing debris, dirt, and old adhesive.
- Levelling – applying levelling compounds or sanding high spots to create an even surface.
- Moisture testing – ensuring the subfloor is dry enough for the flooring material.
- Installing underlayment – adding a layer to improve insulation, soundproofing, and comfort.
