Can You Install Tile Over Vinyl?

A frequently asked question we hear is, “Can I install porcelain tile over vinyl flooring?” The 
short answer is sometimes, but it depends on the condition of the existing floor. Vinyl must be 
firmly bonded, flat, clean, and free of any cushion or movement. So, this will exclude any of the 
LVT or LVP that is commonly installed with an underlayment. Also, if the vinyl is peeling or
damaged, it should be removed before tile installation.
Even when the vinyl appears to be in good shape, the real goal is creating a stable surface. Even 
though, porcelain tile is incredibly durable, it has very little tolerance for movement 
underneath it. Any flexing in the floor below can eventually lead to cracked grout or loose tiles. 
That's why skilled installers often prefer to remove the vinyl and install directly over a properly 
prepared concrete slab or an approved cement backer board or underlayment on a wood subfloor.
If removal isn't practical, the surface needs to be cleaned properly to remove waxes, grease, or 
polishes that could interfere with adhesion. The installer should also make sure that the 
substrate meets the flatness requirements for large-format porcelain and select a high-quality 
mortar recommended by the mortar manufacturer for the specific application.
Every project is a little different, so following the recommendations of both the tile and settingmaterial manufacturers is always a smart approach. Spending a little extra time to prepare the 
substrate is one of the best investments you can make for the longevity of your installation. 
Beautiful porcelain tile deserves a solid foundation, and when the floor underneath is in proper
condition, you'll enjoy a finished surface that performs for years to come, looking just as great 
as when it was installed.
