I am installing cork flooring in my kitchen. Currently, there is a vinyl sheet flooring in the kitchen. Which would be the best course of action:

Leave the vinyl sheeting in place in lieu of vapor barrier?


Remove the vinyl sheeting, clean the concrete, and put down a vapor barrier?

Also, if I install a vapor barrier, (which I really think is necessary) what varieties are there?

Is there a type that you roll on with a paint roller?

I have seen the rolls of vapor barrier in stores. Which would work best? the painted on vapor barrier or the roll of vapor barrier?

Thanks, in advance, for your help.
