Bonding coat onto brick?

I have put a request out to replaster my bathroom in particular to replace old blown plaster and scratch coat round the window which has over the years attracted water ingress from leaky window seals etc.

One plasterer has suggested using bonding directly onto the brick. Would this be correct? I was under the impression that bonding is not waterproof and would therefore not be appropriate for this area.

The walls are double skin without cavity, Victorian semi.
