I'm currently building a green wall / cyclorama room, and one of its properties is that it has an infinity wall (curved walls with an X radius in all the corners).
After a lot of research I decided to go with 3mm HDF for the panels. My question is, considering that the joints between the panels will be filled with mud, sanded down, primed and painted, I cannot afford any kind of movement due to humidity or temperature changes (room will be controlled anyway), as they would crack the paint.
Aside from nailing the panels (I'm using Type C staples), would you also consider glueing them? And if so, wood glue or construction glue?
