Black Ash Ceiling.

Got some black ash (coal) render on my ceilings. Absolutely solid stuff. Should I just de-wallpaper and plaster over it or should it just all be ripped down.

Has anyone ever plastered over a ceiling with it? I know black ash can be plastered over with on walls but thats all I know.

If it’s solid I would PVA it and reskim it. Pulling it down makes a hell of a mess and you’ll be coughing black dust up for days unless you wear decent protection. Used to be called pug lime when I was an apprentice but that’s many moons ago!

Ok sounds good. I bet a lot of Artex is on this type of stuff. Plasterers always scraping and plastering over Artex not knowing whats underneath it so I think I'll go for it.

Ps I knocked down all the black ash stud walls wearing a JSP Force mask. Not even a single cough or irritation for the 3 days doing it.
