Can I tile over vinyl?
We are often asked if it is OK to tile over sheet vinyl.
The answer requires more than a simple yes or no.
Most manufacturers’ of tile cement (thinset) have
developed a specialty thinset for setting tile that
bonds well to sheet vinyl. However, as with all tile
installations, the entire subfloor below the tile is
important – not only the layer to which the tile
is bonded.
To tile over sheet vinyl the following is generally
recommended by most mortar manufacturers:
1) The sheet vinyl must be clean and free of wax or
other bond breakers
2) The sheet vinyl must be single layer only and well
attached
3) It should not be perimeter glued (it often is!)
and it should not have a cushion or foam back.
4) The subfloor below the sheet vinyl must deflect
less than the industry standard L/360 deflection criteria.
In all cases, we do not recommend straying from manufacturer’s
recommendations – you must check with the mortar
manufacturer for their specific installation and product
advice.
