  • Tiling a kitchen floor.
  • Half is covered in bitumen (from parquet floor). Half is a new concrete slab.
  • There is a 35mm level difference across the floor and is fairly lumpy.
Possible solution No.1?:
  • Use latex self-levelling compound such as arditex na.
  • BUT: I am slightly worried the new slab may move and crack along the joint. Which will crack the slc and the tiles.
  • BUT: This solution will offer no insulation and due to the level difference will cost an arm and a leg!
Possible solution No.2?:
  • Lay chipboard tounge and groove flooring. Using an adhesive to take make it level (in a similar fashion to dot and dabbing) then tiling onto that. Maybe screwing it to floor as well
  • BUT: will this stand the test of time?
  • BUT: is there an adhesive available to do this?
Please, please help. Gone round and round in circles with this one. Thank you in advance
