My parents have asked me to lay some porcelein tile in the kitchen. There
is currently some vinyl tile on the floor (the sheet type, not individual
squares) and I assume it has been glued down. Is it okay to put the tile on
the old flooring? If so, do I need a special type of mortar mix, or will
the standard type work. I was wondering about the mortar bonding properly
with the current flooring.
I would appreciate any help and input. Many thanks!
It wont bond to your floor, find out the thickness of the wood, you may
need cement backerboard or wood underlayment for strength, so the tile
doesnt flex and crack, drill a hole and see how thick it is . Depending
on tile type, 1' is minimum, pick your tile, see what it requires. you
need a subfloor that wont move or the job wont last.
Also be sure your floor joists are strong enough first. Some floors
cant take tile unless completely strengthnd, literaly have someone jump
on it while you look in the basement for movement, it depends on how
well the house was built. But you already know if its well built or
not. Just check it all first.
Actually, the house is on a slab foundation, so directly below the old
lineoleum there is concrete. Would you still recommend using backer board
on this? How to go about fastening it? Hammer drill some holes and use
mollys to anchor it? I thought about 1/4" board if this is the last resort.
It is possible to put down mortar and tile over linoleum as long as
you scuff the linoleum with a sander beforehand to get adhesion. Make
sure you look at things like door clearance, etc. before you go
putting down any additional floor covering, you may find that things
don't work properly when you raise the floor level.
Assuming you really mean porcelain and not ceramic...
Porcelain tile is very brittle. You must remove the vinyl and its
adhesive. Be sure you have those little plastic spacers before you
start and layout very carefully. If you haven't done this before, you
really should hire a pro. If you don't want to, then do a complete
dry layout before starting. Bear in mind, good porcelain tile is very
expensive and easy to ruin.
that's not correct.
you can tile over linoleum if it's well stuck down. if it's loose at all, it
has to come up. rough it up a bit, and use latex modified thinset.
read a good tiling book, or go to a real tile store, not a big box, and ask

You might well be correct, but an acquaintance of mine tiled over
linoleum with porcelain and it has cracked in several places. He
(being more than a little upset) had a pro look at it, and the pro
told him that you should never install porcelain tile over anything
but a very rigid subfloor.
Again, Charlie, you might well be right. I have no direct experience
with the stuff.
First of all, how old is the vinyl floor? If it predates about 1978, DON'T
go sanding it without testing it for asbestos content. Not only did some
vinyl contain asbestos, but the adhesive did as well.
The linoleum may not be glued. Many times just the edges are glued or not
at all. I would pull out an appliance and see if it will come up. That way
you don't rip any of it and create an uneven surface. I would also research
any mortar that sticks to linoleum. Linoleum is a very slick surface and it
may not last. And then you'll have a mess on your hands. You could try
buying some of the mortar and doing a test. Glue down an old tile and then
see if you can pull it off the linoleum. Let us know how this works.
