Shower Pan Help! Before it's too late!

Hi! We have an acrylic shower pan that cracked. The contractor has removed that, added extra support under it, then placed cement board in the pan.
Then, he placed the cement (mortar) on the cement board, "smoothed it" out, presumably with the proper slope, and left it to dry.
It dried rough, with pits and sharp edged gravel sticking out of it, and did not mud all the way up to the drain.
The attached two pics show the whole shower pan area, and a closer pic of the rough and gravely area around the drain.
My research has me concerned already. I think the next step is to lay the PCV shower pan liner, but as gravely and rough as the cement is, it seems wrong somehow.
The guys is coming back next weekend, and I am certain something is not right, and would like to do this right the first time!
Thoughts appreciated!!! Thea

Welcome to the forums! Before money changes hands, you may want to review the proper manner in which to build a proper pan. Compare it to what your guy did. Your guy obviously has no idea how to do it.

He may have something to make is smooth before he lays the liner. Call him! Don't wait until he returns.

While not exactly the correct way to do it, as long as he is doing the double slope you may be OK. Floor mud is different than mortar mud in that it is mixed fairly dry and pounded into shape. Because of the rough texture it also shaves easier than thinset mortars.

I can't for the life of me figure out how he proceeds from this point to ensure a waterproof finished product. He hasn't removed any wall tile that I can see to accommodate for a pan liner.

My best guess is that your contractor going to use a paint on membrane like hydroban with the divot method to waterproof the pan. Membranes like Hydroban need to go all the way up the walls to the height of the shower head. Obviousely, since the tile is on the wall, he cant do that. If he is going to use a paint on membrane, do not under any circumstances let him do it. There is no way to waterproof that pan correctly in its current state. The contractor needs to pull out enough tile and cement board to put in a proper pan liner. He also needs to put in a proper curb, as he cannot cover that one with a pan liner expanded lathe and mud. He also needs to use the right deck mud for the preslope and final mud bed.

Oh yeah, almost forgot. Cant really see that drain good. If its the same one he was using for the pan that was there, it is not the right drain and its not gonna work.
