I just had my shower stall “hot moped”. Just wondering how well thinset sticks to the vertical tarred areas. I have a built in seat in the shower that has been also hot moped and wondering if I need to attach hardiboard to it or can I thinset over the tar and attach my tile. I’ve hardiboarded everything except the vertical portion of the seat.
Tiling over hot mop tar?

How did you secure the hardiboard?

Float it or you'll have problems
I would be concerned with throwing screws into a hot tar job.
a friend of my son says i should use that expanded metal and form it exactly to the shape of the bench then embed it in mortar that i run up the vertical and across the seat, so it's almost like having a concrete seat

If not screws then what should he have used? I'm asking because I don't know and would like to learn the proper way of doing things!!!!
The tar is your water barrier. Throwing in screws defeats its purpose. As mentioned before, floating thinset over the mud makes it tile ready with no screw penetration. It is also your job to taper the floor towards the drain.
So your pan is hot mopped but you are referring to the walls above the tar? Yes, way different... and proper.
Unfortunately, your images are not coming through. How are you posting them?
i don't have all the screws installed yet. I'm trying to decide weather to remove the hardiboard and install felt paper then reinstall the hardiboard - i was going to put felt up but i forgot till now. Or maybe just keep going. looking on u-tube some say to put up a moisture barrier and some say not to regardless. I'm going to seal it with Redguard and don't i see how the moisture will get into the hardiboard
