Salt on bricks

[Ollielake88]

I’m hoping someone can give me some advice on a job I’m doing I’ve hacked off a old render the render was a state so water was getting in behind it now some of the wall has salt on bricks I planned to just base it and monocouche it is there something I need to put on top of the salt areas first?
