Would anyone care to venture an opinion about which of the materials (if any) listed in http://www.chemisol.com/argp.htm would be most suitable for applying a waterproofing coat to interior walls? The description of these products is not very explicit about this. The room whose walls are to be coated is a bathroom.
The ACC-30 page explicitly mentions bathrooms.
EDIT: Ecnerwal makes the good point that waterproofing an interior wall does not make much sense. So, I guess a followup question (should I make this a separate one) is whether any special coating/treatment is necessary, or should one simply paint the interior walls?
