Question 31

Should we use a vapor barrier along with the cork underlayment when installing Wood Wise over concrete? For our current basement remodel, we are seriously considering the Wood Wise flooring option by Amorim. This will be going over a concrete floor (still need to conduct a moisture test). The manufacturer states only a 6 or 8 mil vapor barrier is required as an underlayment, but we won't void the warranty with a 2 mm cork underlayment. Since this project is over concrete, should we install a vapor barrier in addition to the cork underlayment. View answer

Question 32

We are thinking of purchasing strand bamboo flooring (USFloors Ming) and using this underneath. Do we still need a vapor barrier between the concrete and the cork underlayment or can you forgo the plastic underlayment (just cork and flooring)? We live in Florida, a very humid climate if that is relevant. View answer
