Wall Mud or Floor Mud First when shower is hot mopped

[GWB]

Doing a Shower as follows:
- Plywood subfloor
- Pre-sloped with 3/4" ply with cast iron drain
- Hot mopped floor and up 10 " on sides
- Covered walls with greenboard and overlapped hot mop on walls by 3 inches.
- Bottom of green board sits 7" above hot mopped floor
- Was going to cover green board walls with vapor barrier before I mud.
- As well going to apply diamond lath to walls


Now I am read to mud wall and floor. So my questions are:
1) how far above the hot mopped floor should the lath stop?
2) do I mud the wall or floor first ?
3) I am concerned that the greenboard stands proud of the hot mopped walls by 1/2". As I mentioned, the bottom of the greenboard is 7" above the hot mopped floor. Does that mean I need to wrap the lath beyond the bottom of the greend board and downward "x" inches and then backfill in the 7" band with an extra 1/2" of wall mud (in addition to the normal 1/2" wall mud)???

Thanks,

David

David,
Throw a scrap of greenboard into the shower pan to protect the hot mop while you prep and float the walls. Extend the metal lathe to within an inch or two from the pan. You can *attatch* it to the hot mop with dabs of silicone or strips of duct tape if it's too floppy, but not too many as you want the metal to mostly hang plumb. Fill the void under the greenboard with extra fat mud as you are floating the walls. Remember to consider the final height of the shower pan when laying out the final height of the shower walls.
Best of luck,

Shaughnn,

Thanks for your help. Exactly the kind of advice I was looking for. I appreciate the heads up on accounting for the final height of the shower pan for determing the wall layout.

By the way......small world. Saw your from N. California. Oddly enough I am from the Bay Area......small town north of San Francisco called Novato.

Again, I appreciate you taking the time to help me.
