Can You Put Vinyl Flooring Over Cement Board Siding

Can Vinyl Flooring Be Installed Over Cement Board Siding?

Vinyl flooring is a popular and affordable flooring option, and it can be installed over various subfloors, including cement board. However, it's crucial to consider essential aspects before embarking on this project to ensure a successful and long-lasting installation.

Subfloor Preparation

Proper subfloor preparation is essential for vinyl flooring installation. Cement board is a suitable subfloor for this purpose, provided it is level, smooth, and free of moisture. Any imperfections in the subfloor can transfer to the vinyl flooring, resulting in unevenness or damage.

Leveling the Subfloor

If the cement board subfloor is uneven, it must be leveled before installing vinyl flooring. This can be achieved using a self-leveling compound or a leveling underlayment. Self-leveling compounds are poured over the subfloor and allowed to flow, smoothing out any unevenness. Leveling underlayment, on the other hand, is installed over the subfloor, providing a smooth and level surface for the vinyl flooring.

Moisture Barrier

Moisture can damage vinyl flooring, so it's essential to install a moisture barrier before the vinyl flooring. This barrier prevents moisture from seeping into the subfloor and causing the vinyl flooring to buckle or warp. Typically, a 6-mil polyethylene sheet is used as a moisture barrier.

Adhesive Selection

Choosing the right adhesive is critical for a secure and durable installation. There are various adhesives specifically designed for vinyl flooring. Select an adhesive compatible with both the vinyl flooring and the cement board subfloor. Follow the manufacturer's instructions carefully when applying the adhesive.

Temperature and Humidity Control

Temperature and humidity play a vital role in vinyl flooring installation. The room temperature should be between 65°F and 85°F (18°C and 29°C), and the relative humidity should be between 35% and 65%. Extreme temperature or humidity fluctuations can cause the vinyl flooring to expand or contract, leading to buckling or warping.

Acclimation

Before installing vinyl flooring, it should be acclimated to the room temperature and humidity conditions. This allows the vinyl flooring to adjust to its new environment and reduces the risk of expansion or contraction after installation. The acclimation period typically ranges from 24 to 48 hours.

Professional Installation

While installing vinyl flooring over cement board siding is possible, it's advisable to hire a professional installer. Professional installers have the experience and expertise to ensure proper subfloor preparation, adhesive application, and vinyl flooring installation, ensuring a flawless and durable result.
