Pergo over old vinyl sheet in basement?
I did some searching but didn't find an exact scenario to match this. In my basement (on this side of the house it's at/above grade) I have some old gaudy vinyl sheeting covering the floor. There's a big old ugly seam cover right down the middle and I was thinking about ways to go about fixing this. I've been looking at floating floors/Pergo and read that you can place Pergo over vinyl sheet but if in a basement you'll still need to lay down a moisture barrier. Is this true?
In addition how would I go about making the seam cover level since it's obviously a good bit higher than the flooring? I was thinking about pulling it up and possibly filling the gap (if it's a big enough one) with maybe a folded over underlayment?
In addition the flooring wraps around a little bar but for some reason they didn't bother completely laying down vinyl for about 3/4 behind the bar. Instead it's a beat up, skinny, gappy carpet. I'm assuming I'd have to tear it up but I'd think I would have to but a reducer in since it would be a bit lower than the rest of the floor. Any thoughts? Thanks!
