When trying to scrape off the original paint of my bathroom ceiling,I found some areas are quite hard to be scraped off by using the scrapper. I guess it is caused by the moisture or the previous painter applied flat paints straight onto bare gyprock without primer.
You can see on attached photo, the underneath brown paper is shown after I scrapped paint. Did anyone come across this situation? and is there any ways to scrape without damage the gyprock?
Many thanks!

Gyprock ? Is that a name for Sheetrock? If so moisture above could be a problem even if properly sealed and painted.
The year of construction would be helpful also. Green /blue board are forms of water resistant Sheetrock, as the lighting level is low I cannot tell but it may be green board from my best guess.
Many bathrooms that do not have proper ventilation have issues with ceiling paint even with the best preparation every type of wall board can have issues as the moisture if not exhausted can cause bubbling, mold and many other problems.
