When do you plaster walls

If you have curved walls, the only finishing option available is plastering them. Drywall does not bend. Therefore, you cannot install it on curved walls. Additionally, if you want a premium look on your walls, plaster them. You can also install plaster on already plastered walls to repair or refresh their appearance.
