laminate on concrete ?
We are considering layind down laminate in our lower level walk-out. The installer has said we should lay down 4 mil poly before laying down the underlayment which would be "quietwalk" sold by ******* which already has a vapor barrier....but he says it is not good enough and he would lay down the poly mil first. will this in anyway not alloy the quiet walk to do its job of dispersing moisture etc. Is this a good idea? Could the poly mil get all stinky or moldy from lying against concrete for many many yrs? Thanks
the 2 in 1 foam is all you need ,the extra plastic is just that. it won't hurt and it wont stink.your installer may have seen a reason why he want's to use it. like i said it won't hurt anything.good luck
