Hi,
I have been reading through all the info around No More Ply and your posts on the topic but am still unsure how to level the surface beforehand. Any help much appreciated.
I have old floorboards they are tightly packed however there is some variance in the levels of the boards, and also there is gradual sloping in some areas. Overall the floor is solid and i've secured down lose boards.
I'm not sure if the best thing would be to use a flexible tile adhesive as a filler to level out the unevenness and lay the NMP over the top, or if something else would be needed. How level does the floor need to be?
I am laying in 2 rooms 12 & 14 sq m and a hallway.
thank you

The floor should have less than 3mm deviation over 2 metres..
