Hello,
I'm soon to be tile my bathroom floor. It was tiled by a previous owner directly on to T&G floorboards, and miraculously no tiles ever cracked. The floor is quite stable and surprisingly level; I've replaced some damaged floorboards and removed the previous flexible https://www.tilersforums.com/forums/tile-adhesive/, and screwed everything down tight.
The floor is perfectly level transverse to the floorboards with very minimal cupping (< 1mm across each board).
The room is small (about 1.7 x 1.3m of floor) and has the corner cut out where a chimney runs through the room. The last joist which butts up to the chimney is lower then the others and therefore the floor level drops next to the chimney, by about 5mm. When I lay a 6ft level along the length of the floorboards,they are perfectly level up to the last "good" joist, then there is a downward taper which causes a drop of about 5mm by the wall. this section is about 600mm wide and ~200mm deep, and it will be located underneath a semi-pedestal basin anyway.
I'm thinking that I may well be able to get away with building up this small section with additional https://www.tilersforums.com/forums/tile-adhesive/ under the hardiebacker board. I'm thinking of using 6mm trowel on the whole floor and then back buttering the hardiebacker in the affected section with a 10mm trowel at the edge, and a strip with an 8mm trowel next to that, and then using a long level to set the board evenly on the https://www.tilersforums.com/forums/tile-adhesive/ bed.
Does that sound realistic for such a small section?
thanks in advance
