The real probolem is level flooring and the fear it can pool to a base board quick.MDF crap all over here. Cheap crap! I always stay an inch away from the wall and go back on my knees with a brush and wet spotting towel soaked in tile cleaner. It's a glamours life.
I'll buy that.I'm thinking MDF has little or nothing to do with location.
It's simply cheaper for the home builder/developer than finger jointed primed poplar (or other inexpensive hardwood)
and most of it is "finished" .... doesn't need painted like FJ primed
and there are two different kinds of MDF
the saw dust and resin kind and the pressed paper.
The former will take "some" moisture..the latter is garbage and like a sponge
Does the bottom edge ever come pre primed or just the face?
I haven't seen mdf swell like that unless it's been a wdr job
maybe I've been lucky?
guessing 80% of skirting board I see is mdf
