When it comes to installing a floor covering over concrete or wooden subfloor, the thickness of the material matters. Too thin and the substrate may show through or feel uneven. Too thick and the transition to adjacent surfaces may become problematic, especially if they are already installed. So, what’s the maximum thickness of the floor covering that you can use? Let’s find out.
Consider the substrate.
Before you choose a floor covering, you need to assess the condition of the substrate. Concrete subfloors should be flat, dry, and free of cracks or contaminants that may interfere with adhesion. Wooden (Electric underfloor heating) subfloors should be level, stable, and properly ventilated to avoid moisture build-up. Depending on the type and thickness of the floor covering, you may need to prepare the substrate by smoothing, levelling, or priming it.
Check the manufacturer’s recommendations.
Each type of floor covering has different requirements in terms of thickness, installation method, and underlayment. For example, carpet may need a thin foam pad or tack strip, while tile may need a cement backer board or an uncoupling membrane. Before you buy any materials, read the manufacturer’s specifications carefully and follow them to ensure a proper installation.
Follow the industry standards.
In general, the maximum thickness of the floor covering should not exceed 1 inch (25 mm), including the underlayment, if any. This is the standard set by most flooring associations, such as the National Wood Flooring Association (NWFA), the Ceramic Tile and Stone Association of Arizona (CTSA), or the Carpet and Rug Institute (CRI). Exceeding this limit may result in excessive deflection, or bending, of the subfloor, which can cause cracks, squeaks, or other damage.
Consider alternative solutions.
If you need a thicker floor covering, you may want to consider alternative solutions, such as raising the adjacent surfaces, using a transition strip, or installing a subfloor system. For example, if you want to install hardwood flooring over a concrete slab that is uneven or damp, you can use a plywood subfloor or a self-leveling compound to create a flat and dry surface. If you want to install carpet in a room with different floor heights, you can use a reducer strip or a threshold to create a smooth and safe transition.
