I am changing use of the single brick outhouse which is attached to the side of the house for a utility room.
Most of it I have tiled but there is an enclosed toilet which I will tile the lower walls and wish to add plaster board to the top half so how do I do it.
I bought plaster nails but my son says I have to dot and dab the boards to the walls and he says I need to buy ready mixed plaster and add water
Is this correct as I will use wallpaper and would hate it to go black with mildew
