I've never seen anyone wallpaper the face of a brick or concrete block wall. If this is intended to mean anything they should use real wall assemblies. I suspect the cost of the paper would be better spent on upgrading the construction from the typical (sheathing and framing materials you can cut with utility knives and metal snips) to something heavier duty.
