sorry if this has been covered before i have been reding lots of different forums about this and getting conflicting information!
i want to tile my kitchen diner before fitting a new kitchen so the kitchen units sit ontop of the tiles. i was thinking of using either slate or poreclain tiles ive not decided yet.
the area is 2610mm x 6070mm, the kitchen part has been tiled by the previos owner it looks like they have tiled over 6mm ply, there are a few little cracks in some of those tiles but are generally good. i am going to remove all these old liles. the diner is currently the original 22mm pine (i think) T+G floorboards nailed down with joists at 400mm centres and is in good condition.
i understand i am going to have to board the floor with something (ply/widiboard/aquaboard?) but i am not sure what is best and how thick to use.
