Ceramic floor tiles and plywood problem

[Andy Allen]

So we're saying this floor hasn't failed? We are talking about removing tiles etc im guessing not.

Im sort of inclined to agree with Widler. Sounding like im the only one. But IF the floor is deflection free after removing tiles and in reasonable order then id clean up and prime the 6mm ply putting in more 25mm screws to ensure its well fixed to the chipboard. Then i would glue and screw hardie backer over the top. Then tile.

6mm ply is pish for an overlay. But fixing hbb over ply is more preferable than chipboard anyway.

bloody traitor......:lol:

You rebel you 😉

If you can get a driver bit into as many screw heads as possible, that would cut down possible damage to chipboard......as for filling holes/damage........you could use fastflex......but if just a little damage, then you could just use decorators caulk or similar.

Then just use a flexible adhesive (fast flex would be belt & braces, but chuffing expensive) As for screwing/countersinking, 6mm hardi is usually ok, so should countersink in one hit.

Then use the same adhesive for tiling. Also flexi grout.....or better still, wide joint grout with flex additive (sold separately)

That's your job for the weekend sorted.

Thanks very much CJ for the info!

I started removing the plywood and tiles and I will finish removing them on Saturday.

The bathroom installer fitted the plywood with short screws and the plywood is not glued to the chipboard flooring, so that is helping to lift the plywood off easier with a crow bar.

Thanks again for the help!

Personally I'd remove the 6mm ply and replace with 6mm Hardie Backer glued and screwed....

Just bumping some of the older popular (sometimes not so popular) threads. Probably wont be current discussion these days but I just need to do it. So just ignore the thread if it's not current for you.
