Looking for some advice please, house built in 1906, solid 9" wall. Lime mortar, lime plaster. House has been gutted back to brick.

What is the best way to go about rendering the internal walls, plenty of arguments regarding cement not allowing soft brick to breath ect, what's the alternative. Is lime a pain and more expensive?

Can you get away with sand and cement with a waterproofer and salt inhibitor.

There was areas of the house with cement render and the birck work behind this appears damp in the mortar joints, where the S&C ends and lime plaster starts brickwork and mortar joints is bone dry.

Not sure if dampness behind S&C is partly due to house being empty and not heated for 18 months, even so the original ash lime render and plaster is bone dry behind, so makes you wonder. Practically every old house has S&C render internally now so is it just a case of applying it and forgetting about the damage being done underneath, not a great thought but if you can't beat them.. Cheers

Should also have stated the rear of property is pebble dashed in cement, front bay is original brick, dash above bay up to roof. So not sure how this will affect lime if put inside
