6mm ply and warm-up underfloor heating-best flexi tile adhesive??

[Hayden Goy]

For what good the ply will do for insulation with the ufh then i would just rip it up and tile onto the floor it's self...

Honestly we are not giving you advice to cause you grief, we are here to make sure you have a long lasting installation....Your tiler needs educating as well i think...

Do yourself a big favour and remove the ply...and just tile the floor ...you will probs need to mechanicaly remove the glue but you want the job done right...

The choice is yours really and we wish you good luck....

that would mean me ripping the kitchen out and i cannot do that.

thanks for your time.

nothing chap only the fitted kitchen

If it was me, I would cut the play at the perifery of the kitchen and the units (leaving them in situ) and lift the ply away completely. Speak to our sponsors Uheat and get some 6mm insulating backer board and glue this down where the ply was originally, with proper tiling adhesive and if possible, as Dave has said, plug and screw it as well. Lay your ufh mats/cable and then cover over with SLC. once the SLC has set tile you floor as you were going to do.

You say cost is an issue here. Any additional cost you incur will be more than made up in savings on running your heating system with the insulating board installed and in addition, your tiling will have a much better chance of survival.

whats the thinest you can get??

Hi

6mm is the thinest, so thats the same as the ply and alot stronger.

Good luck

Why don't you cut up the 6mm plywood where you are going to put the tiles and underfloor heating and replace it with 6mm insulation boards.
You won't have to go under your kitchen units and this way you will get the full benefit of 200watt heating.

You can just do as grumpy say's and cut the ply at the units....and then lay 6mm insulation boards with flexible adhesive.....and NOT screwed and plugged...:lol:..( only ply russ)..

I'am a slow typer - by the time I find my glasses, make myself a drink, read all the comments its 10mins to post.
It just goes to show - great minds think like proper tilers.
