swmbo wants ceramic tiles on our soon-to-be-new en-suite floor. The floor is
chipboard flooring, and creaks a little.
Is it possible to put tiles on such a floor without them cracking/breaking
If so, must any precautions be taken?
Failing that, it will be laminate.
I tiled the chipboard floor in our en-suite five years ago and there
have been no problems. It is essential that the chipboard is sound and
any areas which have been wet and have 'expanded' are replaced. It
should all be screwed down securely so that it is absolutely rigid and I
ran dilute PVA adhesive into all the joints to be doubly sure that there
would be no residual creaking. The surface was then sealed with a PVA
I used a two-part adhesive specially designed for fixing ceramic floor
tiles to chipboard consisting of a cement based powder and liquid latex.
The grout was a special type as well and seemed to consist of cement and
ground up rubber tyres!
The join between the floor and walls was sealed with an acrylic mastic.
Hope this helps - good luck!

follow the instructions and it is perfect for the job.
Importantly you MUST then also grout with BAl flexible grout.
Suggest for your application the choice would be BAL Flex adhesive - 2 part
and BAL Superflex wide joint grout.
It ain't cheap but it does the job perfectly.
Thanks for the replys so far.
Existing boards are affected by water. The problem is they have been layed
before the partition walls have been built - ie they go under the walls.
Given that there is no way I am moving the walls to lift the boards,
presumably they need to be cut close to the walls. However, they will also
need to be cut above joists, otherwise there would be no support at the ends
of the replacement boards.
Any suggestions on how to best achieve this.

What about just covering the existing floor with 6mm ply and screwing
tight every 6 inches before tiling over, as a previous poster suggested?
- That's what I'd be tempted to do if they were normal floorboards. And
if the floor is particularly non-level in places, use thicker ply
(9mm/12mm) for its rigidity.
If you really want to replace as much of the chipboard as possible then
find the closest joists to each wall, cut out over the joists and
replace with similar thickness of ply. However, you would still need to
seal around the edge of the room where there is still chipboard.
So, unless there is a very good reason for you wanting rid of the
existing floor covering, I'd not bother cutting it out - just cover over
it and be done with it as it just ain't worth the effort.
If the extra floor height is going to be a problem with the existing
door, just shave the necessary amount off the bottom of the door.
