Existing non-cushioned residential sheet vinyl that is well bonded should be lightly sanded and cleaned. Then ceramic or porcelain tile can be installed using a two-part cement-based mortar and liquid additive such as MAPEI Uncoupling Membrane Mortar mixed with MAPEI Polymer Additive.
Note: MAPEI products are not recommended or warrantied over any substrate that contains asbestos.
