Can You Install Vinyl Plank Flooring Over Cement Board?

Installing vinyl plank flooring over cement board is a popular choice for many homeowners due to its durability and ease of installation. Cement board is a cement-based backer board that provides a smooth and stable surface for vinyl plank flooring, and it is often used in areas with moisture or high traffic. However, there are a few important considerations to keep in mind before installing vinyl plank flooring over cement board.

Surface Preparation

It is essential to properly prepare the cement board surface before installing vinyl plank flooring. The surface should be clean, level, and free of any debris or imperfections. Any uneven areas or bumps should be sanded down to create a smooth surface. Additionally, the surface should be primed with a cement board primer to help improve the adhesion of the vinyl plank flooring.

Moisture Barrier

A moisture barrier is crucial to prevent moisture from seeping through the cement board and damaging the vinyl plank flooring. A vapor barrier, such as a polyethylene sheet, should be installed over the cement board before laying down the vinyl plank flooring. The vapor barrier should be overlapped by at least 6 inches and taped together to create a watertight seal.

Adhesive Choice

The type of adhesive used to install vinyl plank flooring over cement board is very important. It is recommended to use a high-quality adhesive that is specifically designed for use with vinyl plank flooring and cement board. The adhesive should be applied evenly to the back of the vinyl planks and pressed firmly into place. Allow the adhesive to dry completely before walking on the floor.

Expansion Gap

Vinyl plank flooring expands and contracts with changes in temperature and humidity. It is essential to leave an expansion gap around the perimeter of the room to allow for this movement. The expansion gap should be approximately 1/4 inch wide and can be filled with a caulk or a foam backer rod.

Other Considerations

In addition to the essential aspects mentioned above, there are a few other considerations to keep in mind when installing vinyl plank flooring over cement board:

Use a sharp utility knife to cut the vinyl plank flooring to size.
Stagger the joints of the vinyl plank flooring to create a more natural look.
Allow the vinyl plank flooring to acclimate to the room temperature for at least 24 hours before installing.
Roll out the vinyl plank flooring and press it firmly into place.
Clean the floor with a damp mop after installation.

By following these steps, you can successfully install vinyl plank flooring over cement board and enjoy a beautiful and durable floor for years to come.
