I’m installing one of those “neo-angle” shower stalls over sheetrock, the green stuff. The two front angles and door are aluminum framed glass, the sides against the walls are thin plastic (pvc?) I’ll notch-trowel whatever adhesive the directions recommend, although am open to opinions about the brand I should use. Main question is: should I tape, mud and prime the sheetrock before adhering the plastic the the wall, or will I get better adhesion right against the non-prepped greenrock?
Any other gotch yahs or special techniques from those who do this for a living?
