PREPARING THE SURFACE
Preparing the surface is one of the most important steps when installing vinyl flooring. Since it's a floating floor, LVT can be installed over a wood subfloor, concrete subfloor, or existing tile, so your subfloor must be solid and sound before moving on with the installation. Whatever you do, don't skip these best practices for luxury vinyl tile installation. Each subfloor type may require a few different preparations, but they all need to be as clean and level as possible so that your floating floor sits nicely on the surface. For rooms with permanent fixtures, put those in place first. Install any cabinets, vanities, or tubs in the space before laying LVT around them.
The Floor must be smooth, dry, dust free, free from oil, wax, adhesives, chemicals and other foreign materials.
