how to hang plastic behind shower cement board

trying to remodel an old house with rock lath and plaster walls. walls are good so cut it out exactly 5' above tub to screw cement board on. Since I dont have top plate to staple and tape plastic to how do I fasten it to back of rock lath between studs???

Holmes on homes is always talking about "tuck" tape. dont have anything close to that around here,,,,whats most like it???Typar tape,,foil heat duct tape???anything else??

Also asked about red guard or kerdie for waterproofing cement board,,,. One guy said just use basement block waterproofing paint,,,,huh???

Closest was a plastiguard stuff from Mennards that used a mastic and fiberglass sheet, then more mastic goop out of a bucket. think bucket was 30-40 bucks,,,will one be enough for 1 tub??? Is that the best product???

Lastly, whats best method of cutting holes in cement board for tub spout and water valve handle???

If you are using cement board, you don't really need plastic behind it. The Redgard, or whatever that other stuff is, serves as a moisture barrier.

I use a hole saw for making the spout and valve stem holes because it's fast. But since the holes won't be visible when you're done, they don't need to be pretty. You could make them with a hammer and chisel, or even an old screwdriver.

If you are using cement board, you don't really need plastic behind it.
IF, you are using a topical waterproofing product such as Redgard on the surface.

In the case of Menard's...they sell Mapei HPG, basically the same product as Redgard.

Forget the use of any tape product, that is just plain stupid, typical Holmes idea.

The so-called "goop out of the bucket" is also a mistake, don't use that stuff either. Use thinset mortar for the tile.
