Hi there, I’m a plasterer if 20 years and never had any callback. I did a job last week and the builder just sent me these pictures after the mist coat. I was going over existing multi finish and green moisture resistant board. I gritted the existing finish. The basement area (not all of job) had a previous problem with damp and the application temp was about 8/10 degrees. I have no idea what has happened here as I’ve never seen plastering that bad in my life. Advice would be greatly appreciated. I didn’t do anything in this job that I haven’t done countless times before……. Apart from making it look f****d
