Hi all. Has anyone had any luck with taking off cement render and adding lime render to their home outside which has helped with humidity issues? We have tried everything with our 1920s home to stop the humidity levels from being 80. Completely new roof. Added a large extension to back, added a PIV but nothing has helped. Looking at now taking the render back to brick and adding like render. This is super expensive so just wanted to see if there are any positive outcomes from doing this
