I have about a 200 SF kitchen area with two layers of tile. The bottom
layer is very old, probably installed 40 years ago or more. On top is
a layer of stick-on Armstrong vinyl I installed myself about 15 years

area is sufficiently irregular to make one-piece flooring impractical,
or at least uneconomical, so we're looking at other stuff, such as
the engineered wood products or ceramic tile.
Most of the existing floor is tight & in decent shape, save about 10 SF

Is it likely this will be more easily removed? If so, I'd be
comfortable with a direct application of a thin material on top of the
Lastly, do you have any recommendations as to other flooring products
for application above two layers of tile?
