Tile Giant Advice.....

[kevg]

some of the floors I'll be tiling in my new home are ply. After a trip to tile Giant today I was advised that I wont need backer board to lay on top of the ply, just use mapei proflex then tile on top.

I'm certainly not an expert and from what I have been reading and the advise I got from this forum, it made me pretty nervous as I thought I knew what I needed.

I had planned to get some hardie backer and my adhesive would be a mix of keraflex with latext plus.

Is there more than one way to tile onto ply ? Have I been given the correct advice but can choose either the tile giant way or the way I was planning myself ?

Depends on the ply and where this ply is laid etc,

BS 5385 Code of practice 3.2.4.2
The use of sheets and boards that are subject to movement from changes in moisture content, e.g. wood-based materials such as plywood, chipboard, wood particle boards, etc. should be avoided if at all possible. If such boards have to be used they should be restricted to small areas and tiles should not bridge joints between boards. It is good practice to seal all exposed edges and the backs, but not the faces, of such boards with a suitable sealer to prevent distortion by atmospheric humidity changes. Care should be taken to ensure such boards are not installed in a condition where their moisture content is higher than the ambient equilibrium moisture content once the tiled installation is in use. Failure to observe this can lead to subsequent warping and distortion of the boards with consequent cracking and delamination of the tiling.

I'm a simpleton lol. I think that means I should use a backer board ? *insert embarassed smilie here lol*

That's what I was thinking, but these guys know a hell of a lot more than me, it threw me off guard though. Sometimes when you think what your doing is correct, all it takes if for different advice to put me back to the start.
