A neighbour has removed the old tiles from his bathroom walls and much of
the plaster with them
He wants to prepare the wall for tiling.
The bathroom is to be tiled throughout.
The bathroom suite is also to be replaced
Does he need to replaster first or can he tile directly to the brick?
If he does need to replaster could he dry line with plasterboard?
Is there a special board that can be used in bathrooms for this purpose?
