Hi,
Im planning on tiling my kitchen floor, but am in need of some advice on floor preparation etc. Im planning to use some sort of natural stone tile, and also am planning to install electric underfloor heating.
At the moment the floor is laid with crappy ceramic tiles, which are cracked in several areas and/ or no longer attached to the floor properly. The room has an old concrete sub floor, with no integrated DPM or insulation as it dates from the turn of the century. The previous cowboy who owned the house seems to have applied some sort of (possibly) self levelling bitumen compound which may also have been used as the tile adhesive by the looks of things as theres not much adhesive under the tiles! He claimed this was acting as a DPM, which is interesting as it doesnt even cover the whole floor....
Anyway, main question Im trying to answer is - do I need to try and remove this bitumen stuff before proceeding? My plan for the new tiling was then going to be as follows:
1) fix floor insulation boards to floor with felxible tile adhesive
2) lay out underfloor heating mats
3) use flexible tile adhesive over heating mats to fix new floor tiles
Would it be possible to use a cement based adhesive with quarry tiles, or would this not be a good idea due to the use of the boards? In case anyone asks - despite the lack of a proper in floor dpm - I do not believe the floor to have significant moisture content.
THanks.
