I am laying a Kährs wood parquet floor in my renovated kitchen and I need a sensible solution to preparing the existing floor heights.
Kährs oak, for support. Single plank. 2420x187x15mm
I am laying this over 2 existing floors. 25 year old linoleum matt and a 70cm strip of wood parquet. And a small strip of concrete filler. (I have moved a wall by 70cm).
The 70cm strip of existing parquet kicks up by about 4mm.
And near to this the lino has an 8mm dip in it over a 1sqm oval shape.
So the total difference is 12mm.
Kährs' online info tells me that there can be a total of 3mm difference over 2m of plank, no more.
What do I do? I'm not taking up either floor.
Do I level the dip with sand?
Or do I level with sheet material, say 3mm ply and 1mm card? Or masonite Or something else? Can these sit ok on the organic lino?
Do I grind down the existing parquet and concrete? (The last thing I want to do) Or leave the 4mm hump, ignoring the Kährs 3mm rule.
Thanks for any tips.
