Building a wine cellar in the basement and need to put a vapor barrier over the concrete. I need something that will work to cover the area (5' x 5') and not impact the tile mud that will go over it. Any suggestions?

I'm just taking a shot, but plastic, covered with hardi backer? I read a lot on Kerdi when I did my shower, but just bought a fiberglass floor pan and put plastic on the studs before the hardi board.

There are vapor barrier epoxies on the market. Our product VB-5 will protect up to 12 pounds of vapor emissions. When we apply a cementitous overlay over this, we apply a second coat a place #40 rounded quartz sand to rejection. Once dry sweep real well and apply our overlay product. As with other topicals, just a quick sand to abrade the surface and you're good to go.

Thanks for the response, but pretend I have no idea what your talking about.

A topical vapor barrier epoxy is placed on top of a properly prepped concrete slab to hold back vapor (moisture) coming through the concrete. Depending on the amount of emissions will dictate the product used. These are not a wearable surface and needs to be topped with epoxy or tile. There are combination vapor barrier/mastics on the market. If you are installing the tile yourself, call a local tile supplier and pick his brain. (Not a big box store).
Anyone you talk to will want to know just how much moisture you are having. It's measured by pounds or relative humidity. (Two different types of tests). The least expensive test is the calcium chloride test. You basically clean a 20"x20" area of concrete, pre weigh the little dish of calcium chloride. Place it on the cleaned area. Place the plastic dome over the dish. (It has a pretaped edge). Wait 60-70 hours and then re-weigh the dish. The difference is then added into a handy little formula provided. This will give you the pounds of water pressure coming through the concrete. Most epoxies can handle up to 3 pounds of pressure.... Not sure on mastics.
Do a little research, contact your local professionals (Tile stores) that sell these materials and you'll be good to go.

Contacting your local tile outlet will give you the correct product to apply. They will also be helpful on the mastics and what products work with the type of recommended mastic.
