Fitting of Karndean

[pippala]

Hope someone maybe able to advice?
We have chosen Karndean for our buy to lets.
One has laminate flooring, one has original floor boards.
I understand the Karndean has to be glued on to the floor.
we assumed this could be glued to the laminate or floorboards.
However our kitchen fitter says the laminate has to come up then plyboard laid and the karndean glued to that.
It makes no sense to me as the laminate is a good flat surface.
Is it way of getting another days work/extra money out of us?

he is right, there is movement in any laminate floor and vis a vis the floorboards, just think of the trouble trying to remove the Karndean in future years if it was glued directly to the boards. the surface of the boards is not flat enough anyway, and with time you would be able to see ridges. he is trying to do a good job.
