hi after starting to tile my bathroom it turned in to more than 1 job, the floor around bath,sink and toilet pan were swollen.
the floor is chipboard,the rest of floor looked ok, so i removed these parts and replaced them with same chipboard.
i lay down my plywood(6mm) and screwed it down at every 200mm distance (boy thats a lot of screws).
ive took door of and when dry laying the tiles , just at corner where door is theres a slight rock,( from top right to bottom left), its about a 2-3 mm ( i can fit a plastic school ruler under it) and its only at 1 corner.
i checked the floor and its where the floor comes in under the wall and joins to the hall floorboard (chipboard t&g)
and to lift al that is a major job. will the adhesive correct the rock if i use a little more or will the recomended spread be ok. the tiles are ceramic and the adhesive is Bal Rapidset Flexible... any advice welcome..
(update) i drylayed a few tiles and without cutting them to shape, they also have a small rock in them, just a few tiles, is this a normal characatristic of dry laying tiles and easy overcome, man if tilers have to pull up floor all times i dont envy yous
