Hey all, I am trying to remove my popcorn ceiling. However it is super hard. I dont know how it was put on or what it is but it is extremely hard to remove. I sprayed it with water and I was able to scrape a a first layer of paint but is not coming off in globs like all those nice you tube videos. Why is this so difficult its almost like cement.

We are renovating a house that had chair rails along the walls and we pulled them off. I was told that we'll have to float sheet work where the chair rails were, otherwise the line where the paint stopped would always be visible. I was also tolf that after floating the new sheetrock, the entire room would have to be re-textured so it would look uniform. It looks like the texture was applied under the chair rails, so if I can avoid having to float new sheetrock, I shouldn't have to apply texture. Is there anything that can bail me out of all the work and expense, or is floating sheetrock and putting on new texture the only option?
