I am planning to cover the vinyl floor tiles on a small kitchen floor
with granite tiles. Because of the possibility that the vinyl floor
tiles "may" have asbestos in the adhesive, I am thinking tiling over
the existing vinyl tiles. The problem is that the combined thickness
of the granite tiles / cement backer board / thinset is around 1.25".
I am afraid that this may make the kitchen floor too high above the
adjacent floor. Two sides of the kitchen are open to the living room;
therefore, the border is kind of long relatively to the size of the
kitchen. I am afraid that people will keep tripping over the border
I understand that I can install wooden threshold to try to blend in
with the wooden floor in the living room. But I am afraid that this
may not be enough to transition from the living room floor to the
Have anyone tried something like that before? What's your experience
of doing this? How successful that was?

Lived in a house where that was done years ago. Constantly had kids, family
members tripping over it. Most aggravating, dumb, irritating, and sorry looking
mess I've had to put up with. More skinned knees, spilled food, drinks,etc.
Older people and strangers in particular have major problems with such an
approach. If this happened in a business OSHA would be on your case in a
heartbeat, closely followed by the lawyers.
Dont be a wuss about the vinyl tiles. I can't vouch for all the adhesive
makers, but there always were much cheaper things to compound with than
asbestos. Pull up the tiles, find out in detail what lies underneath, and go
down to the subfloor if possible. Use a sensible respirator, keep dust down
with water and you'll be safer than driving cross town. Good luck.
I agree with jbobst4 however,
Checking wheter the tile or adhesive contains asbestos is not a great expense.
Two appoaches are used- the least expensive of which is the "dye method". You
may want to shop around in your area and find out how much it would cost.
I took the conservative approach and found a lab that did it and found out that
neither the tile or the adhesive contained asbestos. Don't recall what the
cost was but if it was high I sure would have remembered it.
I'd take a sample to a lab. You can't just wear a respirator and think your
protected because when you break the tiles you release fibers into the home;
if you have children consider that. If you smoke, exposure to asbestos is
more hazardous than if a non-smoker were exposed. Do it right, if it
contains asbestos you might have to hire a reputable asbestos removal crew.
Thanks for the warning. The suggestion of using a lab to test a sample
is a good one.
The affected area is very small (7'x7'). I think I can contain the
area with the use of plastic sheet, spray water to keep the dust down,
and a respirator that fits my face.
Thanks for sharing your real life experience with me. This surely
confirms what I have been afraid of. OK, this "raised floor" idea is
Thanks for the advice. This surely makes sense. I have watched "This
Old House Classic" about the way professionals went about removing
asbestos materials. Seem like I need to cover the whole area with
sealed plastic sheet. Good thing I have an air cleaner that has HEAP
filters. Keeping the dust down with water is also a good idea.
I have something that I don't quite understand.
I am under the impression that I should put a cement backer board
under granite tiles or ceramic tiles in order to provide a stable
platform regardless if I am going to remove the vinyl floor tiles or
not. The reason is that the sub floor under the vinyl tiles is
plywood, and I assume that plywood is not a very good platform for
granite tiles or ceramic tiles. This means I really cannot cut down
any of the additional thickness that I will put on the kitchen floor
-- I still need to account for the thickness of the granite tiles, the
cement backer board, and the thinset adhesive.
Can I remove the vinyl floor tiles and simply put granite tiles on top
of the plywood sub-floor assuming that the sub-floor is still rigid?
Then at least I can cut down the additional thickness that I will have
to add onto the kitchen floor.
Any idea? Thanks.
Then, this is likely to be "No". I probably need to add cement backer
boards to support the granite tiles if I really need to replace the
vinyl tiles with granite tiles, or I just need to forget about this
whole thing, and leave the vinyl floor alone. Oh well. Thanks for the
