Robbie, if your intent is to waterproof the walls, you cannot do that with either product you mentioned over gypsum drywall. Only Schluter and, I think now, Laticrete make a sheet-type waterproofing membrane rated for such application.

You could continue with your GoBoard, I think. I'm not at all familiar with their installation instructions nor whether it would suit your application.

My opinion; worth price charged.
