If you walk into old houses with just lime and sand, the walls may be drummy but the walls are still standing so its a proven product. Lime is a proven product so if you rerender (float) using a high lime content say 6 sand 1 cement and 1.5 lime you cant go wrong if all your walls are screeded straight you will have the best proffesional finish and it will look the nicest all your new arches and picture rails will look real nice on straight work

The house is approx. 130 yrs old and yes the brickwork is not straight.
The current footings are sandstone strip blocks and the house has had cracks in the old lime+sand plaster render which I have now stripped back.
I expect that the walls will again crack if I rerender, so I have decided to use plasterboard onto steel furring channels. I am putting in a new dampcourse and going to sel the walls from any lateral damp.......my concern is that air trapped behind the plasterboard will start to create mould just from normal air condensation.......there is no option of putting in ventilation

Provided you have treated the walls for dampness, I cant see that there would be a problem with mould forming. I have stripped a few jobs with this application and have not seen mould forming on the back of the sheets.

I think it would take more than normal condensation in the air to cause mould.
