I highly encourage everyone to use a helper whenever they can. I know it is hard to find good help, but if we don't train the next man up, our trade will slowly die off and be replaced by guys slapping up sheets of thin porcelain on top of acrylic pans.

One thing I like on a two coat is what Davy said, plus you have the option to flush out tile to drywall which he also has steered me on by depressing the wire in the stud bays. You can shim the drywall to plumb or near plumb by having that access behind it and usually a caulked joint will hide minor deviations (if any).

I will definitely have to try it someday. In SoCal they have hot mops, and they often create almost a 1/2" of build-out at the bottom, which creates the high spot in the wall. If I could find a way to get the waterproofing thinner, I would love to be able to flush out a float with the adjacent drywall. I'll have to experiment with the 2-coat, sounds intriguing.

I've worked over a couple hot mops when I was there Isaac, not a bad way to go but our company mostly did liners. The guys I apprenticed from were converted to liners when the military base in 29 Palms, Ca specked for them. Apparently the conclusion was hot mops were more likely to crack then liners in the long haul. I don't know either way which is better. but I can do liners myself so I went that direction.

To flush out to drywall the liner needs to be tight, I either glue my folds or tuck them in a framing gap if possible. I saw a really trick way of folding over the dam not too long ago. He left a gap between his dam and wall and tucked his liner in there and didn't even need a boot or cut the way he folded it. Very slick indeed.

Wish we could see the pic from the outside of the curb. Looks like he created a funnel to the outside of the shower. Also would like to see the wire wrap for the mud sill. My fear is the nailing of cement board to all of this.

The fold directs water back to the shower, I’m not sure I understand the nailing of cement board? The curb gets mud

[tilemanct]

Exactly. I cant tell you how many showers I've torn out due to someone nailing cement board over a liner on a curb.
It happens way more than you think.

Here's the link to a slightly more detailed explanation Dave. https://www.instagram.com/p/Btd16j0F...on_share_sheet

Notice that he left a gap between the bricks and the wall. That way he has room to slide the liner in there.

[Dave Gobis]

Not code compliant but most are not.

[tilemanct]

He didn't show the right side fold being completed. No shot directly from the outside looking in. If the liner is long to the outside when you make that cut you will have that funnel to the outside about 1/2 below the curb. The only way to be sure is the flood test after liner install.

[CaliGrown]

Sure looks cool. What makes it non-compliant?

[Dave Gobis]

Pan has to extend over the face of the curb and extend 3" above the finished curb. No penetrations below that level. Not sure if he has a pitch or not either. Don't care for the folds myself which may or may not be a problem later.

[Just In Tile LLC]

So if one was careful on the first two things (which most on here are) the only problem really is the folds "possibly" being an issue. If the fold returns moisture back to the pan (which it looks to do) I see it being a safer bet than cutting and patching. Of course I have no real data to support my stance on the matter

[John Bridge]

The beauty of using the corner pieces on vinyl shower pans is that the corners do extend flat above the curb on the side walls (as Gobis said). I used to do a fold, but switched when I discovered they made corners (oh so long ago).
