It's a two bedroom flat and and the whole place is to be done, including the kitchen and bathroom which will be done with lino.
Two of the three quotes have said they will use MDF or "thin line" as a preparation layer for the bathroom and kitchen. One of the quotes - the highest one - says they will use two coats of self-leveling "matrix".
I have checked on the thinline / MDF. The manufacturer *specifically* does not recommend it be used in high-humidity areas like bathroom, kitchens and areas adjacent to kitchens.
So why are these people quoting materials be used in places the manufacturer says they should not?
As it stands, I'm likely going to go with the higher quote as they have proposed an appropriate solution for the situation.
Make sense? Or does everyone just use the wrong materials in the wrong places and let fate decide the outcome?
