SO I am creating my own coffered ceilings by creating a grid which I will attach to the ceiling. Then I will nail/glue crown moldings onto this grid to create my coffered ceilings. Now I've made a mockup of my grid for testing purposes using MDF and it all seems nice and stable.
Ive never done anything like this before so Im wondering if Im making a horrible mistake and these ceilings will begin to breakdown having used MDF, or if I should use something else?
I chose MDF because it seems relativly light in weight which seemed like a good idea since I am nailing these up to the ceiling
