You will find the following tips on drywalls very practical and useful for everyday problems

Popcorn ceilings are not very fashionable these days, but this is not the main reason why you should remove them. In most cases, they contain asbestos which is harmful to the human health. They're also hard to be painted over, and will make a mess if they are cracked since they will fill the room and floor with dust.
