Hi, I am Aisha and I live in a marlstone house

[Aisha]

Hi plasterers, I just bought a tyrolean flicker machine ( the plastic blue one) and am lookin for techniques to insulate/plaster my dampy marlstone walls of my 250 years old house with a nhl3,5lime/cork/perlite/diatomine mix by hand. No plasterer in my neighbourhood is working with these materials so I want to do it by myself. As I understand, it has to be ‘airy’ and light to add insulating layer onto the wall. Any tip or trick is welcome!
