We are putting down resilient vinyl planks on top of concrete. We went to get a vapor barrier from Lowes and the guy there said we don't need to use that with this type of flooring? Does that sound right?

Make sure you get every single tiny little pebble up before you do.

Their should be a vapor barrier under your slab

Not sure if the floor still requires one though

That floor needs to be as smooth as a babies behind otherwise it will look like shite.

Not required under vinyl. Like others said, all blemishes in the concrete will show.

I've never used a vapor barrier on the ones I've put down. No problems yet.

Yes that's right. We hired a professional and had it installed throughout our house

Some people aren't familiar with the vinyl plank. They probably think you mean peel and pray style.
If your doing the half inch stuff that is going to replace laminate floors soon, I would recommend a pad like they use on laminate.
That floor, vinyl plank, is about to get real popular.

If you really mean vapor barrier, it's not necessary. If you are talking about an underlayment, however, that is something totally different. An underlayment is a sound barrier that is useful when installing plank on an upper floor to reduce sound transmission to the lower floor. Since you are installing this in a commercial space, it's probably not needed, either.

If it is glue down, like stated numerous times you don't need a vapor barrier. Just make sure slab is super clean and perfectly smooth or you will have issues. If it is a locking LVT (one that clicks together like laminate a vapor barrier is also not necessary. IF you use an underlayment for sound, use one that is specifically designed for LVT. If you use a laminate underlayment it could make the locking system disengage and your floor with look like shite.

Yes because it's probably a direct glue down or the really cheap stuff is peel and stick.

I put vinyl wood planks in a lot of smaller specs I built and it will show every flaw in your slab so going through with a grinder and self-leveling cement might be a good idea.

Ignore djangochained laughing at you because he plays some big shot on here constantly trying to act like he is a mogul. Only new money with tiny penises or people that live well beyond their means act like he does. I'll let you guess which one he is. He also probably doesn't realize that some vinyl planks get into mid-tier real wood pricing because of the quality. The difference comes in with the installation labor.

No vapor barrier needed.

Make sure slab is good and smooth, imperfect rooms will show thru.

Once that's done you can teach a monkey to lay vinyl.

Yes, no barrier is correcr.

You will have to put down a layer of self leveling thin set, glue then the floor. We've got rid of laminate and put down Vinyl and couldn't be happier.

The guy in Lowes is wrong.

At a min, you need to do a moisture test to determine if it's acceptable. If the moisture content is too high, the glue won't stick and your floor will peel up.

My advice to you is to put down the barrier. Min cost that protects you from having to replace your floor.

Trust me

Edit: Are you talking about a floating floor, or a VCT plank flooring that you glue? If you're putting glue, you need moisture barrier. If this is a stupid cheap version of wood flooring with a pad underneath, then you don't need a moisture barrier. It doesn't matter if the slab is above ground or in a basement. Unless you know for a fact the the concrete guy taped all your seams in the plastic and installed the proper thickness, there is no way to guarantee you won't have problems.
