What do you do in this situation????

[andy2306]

I have just removed the tiles in my bathroom, ready for some new ones. It appears someone has spread the adhesive straight onto the wood floor.

My question is, what do you do in this situation? its fairly rippled, I was expecting to lift the old ply and put some more down.

Thanks in advance

spreading the adhesive onto the floor is the way most people tile, if its even and a nice floor its adh onto floor tile onto adh, then when you lift the tiles you get the lovely "wavy" pattern.

if your lifting the floor up totally just forget it and lift it all up ash and ply, if your leaving the ply you need to chip away at it.

Its been tiled straight onto the floorboards, I have no plan to lift and replace with ply,

Should i just chip away as much as possible and then overboard with ply? or chip it away as much as poss and then tile onto the floorboards, hoping that the adhesive levels it all out?

Any tips on what the best tool to chip away at it is?

Thanks
Andy

You could over board with 12mm WBP ply but my advice would be take it all up & start again using minimum 18mm WBP ply as a base & use only a quality trade flexible adhesive & grout, not the DIY shed stuff.

if the floorboards are sound enough to tile onto you could level it with latex levelling. then use a flexi adh and flexi grout

That sounds interesting, the floorboards are victorian and very sound, it was crime to just splash adhesive on them in the 1st place, but now its done i just want a level base to start off with.

This stuff sounds like it could be what im after, I dont really want to rip everything up and replace, and getting boards without a van is difficult.

Whats it like to work with? I have 4.2sm to level, do you know how much i will need? Ive knocked all the peaks of? whats the best one to use?

Final question, Im using an undertile heating mat, would this be suitable to use with that? and could i use the leveling compond to secure the underfloor heating mat?

there are a few about, most stores sell a cpl diff types, so depending what type you buy would be how many sq metres per bag, but most will do your small area it depends on what mm you need to apply.

check your instructions on the ufh but i would personally do the latex, then use flexi adhesive to secure the mat.
