I just received a sample pack from one of my suppliers with MDF interior moldings (casing, base, chair rail, crown, etc). I am sourcing out material for a high end condo project. Anyone have any experience with MDF moldings? These are factory primed and really look like nice profiles and are less expensive than finger jointed pine! I am concerned with long term calbacks relating to shrinking/expanding and splitting. I have used MDF on many other projects but we milled on site 4 x 8 boards mostly for raised panel applications.
