Laying ceramic floor tiles

[tintin]

just to set the record straight it is possible to tile directly onto chipboard provided it is the water resistant type (green), plywood can also be used 19mm min (correct grade) as like chipboard it is inert and any expansion or contraction is negligable but it is imperative that the correct adhesive is used for the type of surface.

Moisture resistant chip board cannot be guaranteed to tile directly!

If you use flexi adhesive they still lift and crack
If you pva/prime it they still lift and crack.

We have tiled succesfully on moisture resistant mdf but not chip!

not wanting to get into an argument ,"so i shall say this only once" ,use the correct adhesive! you could also use the correct water resistant membrane on top of the chipboard and get an even better adhesion. on a job i worked on this was done in 22 shower rooms and 6 years later still no movement of the tiles.

We could and indeed would use a membrane of some sort in future (the cheapest form of which wouild be 9mm ply) but thats not Tiling on chipboard !
As i said we have TRIED all reccomended adhesives for this type of floor but to no avail. ( despite having built the house we then had to raise the bathroom floors by 9mm, adding a layer of ply, because no adhesive manufacturer could give us a guarantee they wouldn't lift again)
this was about a year ago, since the ply there have been no call backs!

can't get my head round why 41/2 inches is so important , does this mean your car/truck sticks out onto the path ,which i suppose could be classed as an obstruction,can't you angle it to give you more length? i didn't know there was a length stipulation! i know most councils have nominated contractors for doing the work dropping curbs etc but these tend to ring the prices so that they are all about the same cost.

it has to be certain length from house but has to be square/straight line,not to do with kerb drop

i have not got a drive as such, but i live in a house which has an "L" shaped front garden at the end of the bottom leg of the L i have a dropped curb going across the path up to my gates behind which is a graveled area 16 ft deep by 18 ft wide where i keep my 3 vehicles and at no time did length or width come into the planning equation they were only interested in the fencing i was to put between me and next door and its height,so i would think a visit to the planning department might be in order to find out the why's and wherefors of your problem.

Well the floor is still down . Relatives turned up unanouced on drive yesterday morning just as I was about to start !!
They went out today so I made a start . Took off skirting boards and ran a power saw down the joints of chipboard and took one up. There are no joists !! Basically it is a block and beam floor with 50mm of polystyrene and then the chip board floor layed ontop . No wonder the thing is so uneven and moves when you tread on it .
Spoke to a local guy who says this type of floor is no longer recommended by Building Control as the polystyrene breaks down and the floor moves , just like this one .
We have now decided to remove the floor and polysyrene and screw 4x2 studding on its side to the block and beam floor every 600mm and then infill with the polystyrene and then screw the 3/4" ply to it and then tile over .
No need for the under tile heating as the polystyrene will be good enough insulation I think .
